Global Routing Infrastructure Control And Data Flow Governance

1. Introduction

Global Routing Infrastructure Control and Data Flow Governance concerns the legal and competition-law consequences of controlling the infrastructure that determines how Internet traffic moves between networks, countries, cloud platforms, content providers, data centres, and end users.

At the technical level, Internet routing relies heavily on the Border Gateway Protocol (BGP) and related routing infrastructure. At the economic level, control over routing can determine:

• which network can reach which destination;
• the speed, reliability, and cost of connectivity;
• access to cloud and content services;
• interconnection and peering opportunities;
• resilience against outages and attacks;
• the location and jurisdictional path of data;
• the ability of competitors to reach customers;
• whether traffic is degraded, redirected, blocked, or prioritized.

Consequently, routing infrastructure can become an important bottleneck, essential facility, strategic infrastructure, or gatekeeping layer.

The legal problem is not that operating a routing network is inherently unlawful. The concern arises when a powerful undertaking uses control over routing or interconnection to exclude rivals, discriminate between traffic, foreclose downstream markets, extract excessive terms, or manipulate data flows.

2. Meaning of Global Routing Infrastructure Control

Global routing infrastructure includes several interconnected layers:

1. Backbone networks
2. Internet Service Providers (ISPs)
3. Autonomous Systems (ASes)
4. BGP routing systems
5. Internet Exchange Points (IXPs)
6. Submarine cables
7. Data centres
8. Content Delivery Networks (CDNs)
9. Cloud-network infrastructure
10. DNS and addressing infrastructure
11. Transit providers
12. Peering arrangements
13. Routing-security systems such as RPKI
14. Network-management and traffic-engineering platforms

A company does not necessarily need to own all these components to exercise significant control. Control over a strategically important layer can create substantial leverage over the remainder of the ecosystem.

3. Why Routing Is Economically Important

Routing is not merely a technical function.

Suppose Network A controls a major transit route between several countries and Network B competes with A in cloud services.

If A:

• delays B's traffic,
• imposes discriminatory interconnection charges,
• refuses reasonable peering,
• selectively withdraws routes,
• provides superior routing to its own cloud platform,
• or conditions connectivity on purchasing another service,

the routing decision can affect competition in downstream markets.

Therefore:

Routing control can become a form of infrastructure-based market power.

This is particularly important because users often cannot see routing decisions. A consumer may simply observe that one service is "slow," without knowing that the underlying cause is interconnection or traffic-management conduct.

4. Data Flow Governance

Data-flow governance concerns the rules and mechanisms determining:

• where data travels;
• through which networks it travels;
• who controls the transmission path;
• where data is processed;
• where data is stored;
• which jurisdictions receive the data;
• whether data may cross borders;
• whether particular traffic receives priority;
• and what technical or legal restrictions apply to routing.

It therefore sits at the intersection of:

competition law + telecommunications regulation + data protection + cybersecurity + national security + digital sovereignty.

5. Relevant Competition-Law Theories

A. Abuse of Dominance

A dominant routing or interconnection provider may violate competition law where it uses infrastructure control to exclude competitors.

Possible conduct includes:

• discriminatory access;
• refusal to interconnect;
• discriminatory routing;
• excessive access prices;
• tying;
• bundling;
• margin squeeze;
• self-preferencing;
• degradation of rival services.

B. Essential-Facilities Theory

A routing infrastructure may potentially qualify as an essential facility where:

1. access is indispensable;
2. duplication is economically or technically impracticable;
3. denial eliminates or seriously restricts competition;
4. access can reasonably be provided.

However, courts generally apply this doctrine cautiously.

The mere fact that infrastructure is important does not automatically create a legal duty to provide access.

6. Refusal to Deal and Interconnection

Interconnection is particularly important.

A network may theoretically refuse to connect with another network. Competition concerns become stronger where:

• the refusing party is dominant;
• the connection is indispensable;
• refusal excludes a competitor;
• there is no legitimate technical justification;
• access was previously provided;
• the refusal is designed to protect an adjacent market.

This makes routing governance closely related to traditional refusal-to-deal doctrine.

7. Discriminatory Routing

A powerful network could theoretically distinguish between:

• its own traffic;
• affiliated companies;
• competing platforms;
• enterprise customers;
• content providers;
• specific geographic regions.

For competition law, the central question is whether such differentiation produces anticompetitive foreclosure.

Technical differentiation is not automatically unlawful.

For example, traffic engineering may legitimately respond to:

• congestion;
• latency;
• cybersecurity;
• reliability;
• network capacity;
• emergency conditions.

The legal problem arises where technical justification becomes a mechanism for commercial exclusion.

8. Self-Preferencing Through Routing

Suppose an integrated digital company owns:

• a backbone network,
• cloud infrastructure,
• CDN services,
• a search engine,
• and an advertising platform.

It could potentially route its own services through faster or more reliable infrastructure while rivals receive inferior connectivity.

This creates a form of infrastructure-level self-preferencing.

The competitive theory resembles self-preferencing concerns in digital platforms, but the bottleneck exists deeper in the technical stack.

9. Margin Squeeze

A vertically integrated routing provider may supply wholesale connectivity to competitors while competing against them downstream.

A potential margin squeeze occurs where:

wholesale access prices + unavoidable downstream costs > economically viable retail price.

The provider can therefore make downstream competition unprofitable without formally refusing access.

This is particularly relevant where the upstream routing infrastructure is difficult to duplicate.

10. Traffic Prioritisation

Traffic prioritisation can produce competition concerns where the infrastructure owner gives preferential treatment to:

• affiliated services;
• preferred content providers;
• paying platforms;
• vertically integrated cloud services.

The assessment must distinguish legitimate network management from commercially motivated discrimination.

11. BGP and Competitive Governance

BGP permits autonomous systems to announce routes and select paths.

Its decentralized architecture creates both benefits and vulnerabilities.

Potential competitive problems include:

Route manipulation

A dominant network could manipulate route announcements to influence traffic flows.

Route withdrawal

Withdrawal can make rival services less reachable.

Selective routing

Specific destinations may receive inferior routes.

Interconnection leverage

Control over strategically important connections can affect rivals' costs.

Information asymmetry

The infrastructure operator may possess superior information concerning:

• traffic volumes;
• destinations;
• network congestion;
• latency;
• customer relationships;
• route availability.

This information advantage can itself become strategically valuable.

12. Six Important Case Laws

Because there are relatively few reported judgments directly addressing BGP manipulation as a competition-law violation, the most useful authorities come from telecommunications, essential facilities, Internet infrastructure, interoperability, and digital-platform cases.

Case 1: United States v. AT&T

United States v. AT&T Co., 524 F. Supp. 1336 (D.D.C. 1981)

The historic AT&T litigation is fundamental to understanding infrastructure control.

AT&T controlled significant telecommunications infrastructure and used its position to structure access to the network and related telecommunications markets.

Relevance

The case demonstrates how control over communications infrastructure can create competitive concerns where an infrastructure owner can disadvantage downstream competitors.

Principle

Infrastructure ownership cannot necessarily be separated from competition in markets dependent upon that infrastructure.

Application to routing

A dominant backbone or interconnection operator that controls access to an indispensable communications network may attract similar structural scrutiny.

13. Case 2: MCI Communications Corp. v. AT&T

MCI Communications Corp. v. AT&T, 708 F.2d 1081 (7th Cir. 1983)

This is one of the leading American essential-facilities cases.

The dispute concerned AT&T's telecommunications network and MCI's access to the infrastructure required to compete.

The Seventh Circuit articulated important considerations concerning essential facilities, including whether:

• the facility is controlled by a monopolist;
• competitors cannot reasonably duplicate it;
• access is necessary for competition;
• access can feasibly be provided.

Importance

The case provides a classic framework for analyzing infrastructure bottlenecks.

Routing application

A globally dominant routing/interconnection facility could potentially raise similar questions where:

• alternative routes are unavailable or economically impracticable;
• denial prevents effective competition;
• the infrastructure owner has no legitimate technical justification.

14. Case 3: Bronner v. Mediaprint

Oscar Bronner GmbH & Co. KG v. Mediaprint Zeitungs und Zeitschriftenverlag GmbH & Co. KG, C-7/97

The Court of Justice of the European Union adopted a restrictive approach to essential-facilities/refusal-to-deal doctrine.

The Court emphasized the importance of demonstrating that the infrastructure is genuinely indispensable and that there is no real or potential substitute.

Importance

This prevents competition law from turning every commercially useful infrastructure into a mandatory-access facility.

Routing application

A company seeking access to a particular international routing network would need to establish more than convenience.

It would have to demonstrate something approaching indispensability.

15. Case 4: IMS Health

IMS Health GmbH & Co. OHG v. NDC Health GmbH & Co. KG, Joined Cases C-418/01

The CJEU considered when refusal to license or provide access to a protected system could constitute an abuse of dominance.

The Court identified strict conditions concerning:

• indispensability;
• elimination of competition;
• prevention of a new product or service;
• absence of objective justification.

Routing significance

This reasoning is relevant to proprietary routing systems, network databases, technical interfaces, and infrastructure-control systems.

A dominant operator cannot automatically be required to disclose or provide access to every proprietary technical asset.

16. Case 5: Slovak Telekom

Slovak Telekom a.s. v. European Commission, Joined Cases C-165/19 P and C-166/19 P

This case involved access to telecommunications infrastructure and abusive conduct involving access conditions and margin squeeze.

The Court upheld important aspects of the Commission's competition-law analysis.

Significance

The case illustrates that infrastructure-related dominance can generate competition problems even where access is technically offered.

The issue can therefore be:

not merely whether access exists, but whether the terms of access permit effective competition.

Routing application

A dominant transit provider could theoretically provide access while imposing:

• discriminatory charges;
• restrictive technical conditions;
• unreasonable capacity requirements;
• discriminatory quality levels.

Such conduct may substantially impair competitors without constituting an outright refusal.

17. Case 6: Deutsche Telekom

Deutsche Telekom AG v. European Commission, C-280/08 P

The case concerned telecommunications infrastructure and margin squeeze.

The CJEU confirmed that a dominant vertically integrated undertaking may abuse its position by setting upstream and downstream prices in a manner that makes effective downstream competition impossible.

Routing relevance

The same economic structure can arise in Internet infrastructure.

For example:

Wholesale routing access → downstream cloud/content market

If a dominant operator supplies routing capacity to competitors but simultaneously competes downstream, discriminatory pricing can create foreclosure.

18. Case 7: Google Shopping

Google LLC and Alphabet Inc. v. European Commission, Case C-48/22 P

The Google Shopping litigation concerns the relationship between dominance in one digital layer and competitive advantages obtained in an adjacent market.

Although it does not concern BGP directly, it is highly relevant to digital infrastructure self-preferencing.

Routing analogy

If an infrastructure operator controls a critical routing layer and gives preferential routing to its affiliated services, competition authorities may examine whether the conduct advantages the integrated service over rivals.

The critical question becomes whether the infrastructure is being used to extend market power into an adjacent market.

19. Case 8: Android

Google LLC v. European Commission, Case T-604/18

The General Court examined Google's contractual and ecosystem practices involving Android.

The case illustrates how control over one technological layer can be leveraged across interconnected digital markets.

Routing significance

Global routing infrastructure similarly creates an ecosystem effect:

network control → connectivity advantage → platform advantage → user foreclosure.

The more layers controlled by the same undertaking, the greater the possibility of leveraging infrastructure power.

20. Synthesis of the Case Law

21. Data Localization and Routing

Routing governance also intersects with data localization.

Governments may require certain categories of data to:

• remain within national borders;
• be processed domestically;
• be stored in designated jurisdictions;
• pass through approved gateways.

These requirements can affect competition by increasing the cost of serving a market.

A large incumbent with domestic infrastructure may benefit disproportionately from localization requirements because smaller foreign competitors must construct new infrastructure.

Thus:

Data sovereignty can unintentionally become a source of structural competitive advantage.

22. National-Security Routing Controls

Governments increasingly view routing infrastructure as critical infrastructure.

Possible measures include:

• blocking particular routes;
• restricting foreign network operators;
• requiring domestic routing;
• controlling submarine cable access;
• mandating cybersecurity standards;
• restricting foreign ownership;
• requiring lawful interception capabilities.

Such measures may be legitimate for national security.

However, competition concerns arise where ostensibly security-based measures are designed or applied in a discriminatory manner to protect domestic incumbents.

23. Cybersecurity and Competition

Routing security technologies such as RPKI can improve network integrity.

But technical standards may also create competitive effects.

If compliance with a routing-security standard requires:

• proprietary technology;
• access to a closed registry;
• licensing from one supplier;
• expensive certification;

smaller competitors may face higher barriers to entry.

Therefore, routing-security governance should distinguish:

genuine security requirements

from

strategic technical barriers to competition.

24. Internet Exchange Points

IXPs allow networks to exchange traffic directly.

They can reduce dependence on expensive transit providers.

Consequently, control over a strategically important IXP may affect:

• transit costs;
• latency;
• network resilience;
• local content delivery;
• market entry.

A dominant operator that controls an IXP could potentially disadvantage competitors through:

• discriminatory membership rules;
• exclusionary pricing;
• preferential port allocation;
• refusal of interconnection;
• unequal technical treatment.

25. Submarine Cables

Submarine cables are particularly significant for global routing.

A limited number of cable systems connect many regions.

Control over:

• cable ownership;
• landing stations;
• capacity allocation;
• maintenance;
• repair;
• access rights

can produce substantial strategic power.

Competition authorities therefore need to examine cable infrastructure not merely as telecommunications infrastructure but as a possible cross-border competitive bottleneck.

26. Cloud and CDN Routing

Cloud providers increasingly operate private global networks.

A cloud provider can combine:

compute + storage + CDN + backbone + DNS + security + routing.

This creates substantial vertical integration.

A competitor may technically be able to access the Internet but still face disadvantages because the integrated provider controls:

• latency;
• caching;
• network paths;
• edge locations;
• security layers;
• cloud interconnection.

This creates a new category of infrastructure-mediated digital foreclosure.

27. Data Flow as a Competitive Input

Data movement itself can be treated as an economically significant input.

Examples include:

• financial transactions;
• cloud workloads;
• AI inference requests;
• advertising requests;
• video streams;
• autonomous-vehicle data;
• IoT communications;
• industrial-control information.

If an infrastructure provider can determine how these flows reach their destination, it may influence competition in downstream markets.

28. AI and Autonomous Routing

The problem becomes more complicated when routing is controlled by AI.

An AI routing system may dynamically determine:

• network paths;
• congestion responses;
• capacity allocation;
• priority;
• latency optimization;
• interconnection choices.

Suppose the algorithm consistently routes an affiliated company's traffic through premium infrastructure while degrading competing traffic.

The legal question becomes:

Who is responsible for an algorithmically produced exclusionary routing outcome?

Potential responsibility can attach to:

• the infrastructure owner;
• the algorithm designer;
• the network operator;
• the vertically integrated platform;
• potentially multiple entities depending on the legal framework.

29. Algorithmic Collusion

Routing systems also create potential coordination risks.

Multiple network operators could use automated systems that:

• observe competitors' routing decisions;
• rapidly respond to pricing;
• coordinate transit prices;
• stabilize market shares.

Even without direct human communication, competition authorities may examine whether algorithmic systems facilitate coordinated conduct.

The difficulty is distinguishing:

independent algorithmic adaptation

from

concerted conduct or intentionally designed coordination.

30. Cross-Border Regulatory Conflict

Global routing inherently crosses jurisdictions.

One country may require:

Data must remain inside the country.

Another may require:

Certain information must be accessible to domestic authorities.

A third may impose:

Routing must use approved national infrastructure.

The resulting obligations can conflict.

This creates the possibility of:

• regulatory fragmentation;
• increased compliance costs;
• discriminatory routing;
• duplicate infrastructure;
• slower cross-border services;
• barriers to market entry.

31. Competition-Neutral Routing Governance

A sound regulatory framework should establish principles such as:

1. Non-discrimination

Equivalent networks should receive equivalent technical treatment unless objective differences justify different treatment.

2. Transparency

Material routing policies should be sufficiently transparent to permit regulatory and commercial scrutiny.

3. Interoperability

Routing systems should support open technical standards.

4. Proportionality

Security and sovereignty restrictions should not exceed what is necessary.

5. Access

Where infrastructure is genuinely indispensable, appropriate access obligations may be considered.

6. Security

Competition policy should not compromise legitimate cybersecurity requirements.

7. Accountability

AI-driven routing decisions should be auditable.

32. Regulatory Remedies

Competition authorities could employ several remedies.

Structural remedies

In extreme circumstances:

• separation of network and downstream operations;
• divestiture;
• independent infrastructure governance.

Behavioural remedies

More commonly:

• non-discrimination obligations;
• access commitments;
• transparent interconnection terms;
• interoperability;
• monitoring;
• audit rights.

Algorithmic remedies

For AI-controlled routing:

• audit logs;
• explainability requirements;
• independent testing;
• anti-discrimination monitoring;
• algorithm-change notification.

33. Economic Vulnerability

Routing concentration can create systemic economic vulnerability.

If a small number of operators control critical routes, failure or abuse can affect:

• financial markets;
• hospitals;
• governments;
• cloud platforms;
• supply chains;
• communications;
• transportation systems.

Thus, routing infrastructure presents a dual problem:

competition risk + systemic infrastructure risk.

A network can therefore be competitively important even where conventional market-share statistics underestimate its significance.

34. Market Definition Problems

Traditional competition analysis may define markets around:

• Internet access;
• transit;
• telecommunications;
• cloud services.

But global routing requires more granular analysis.

Possible relevant markets include:

• international IP transit;
• regional transit;
• interconnection;
• IXP services;
• submarine-cable capacity;
• CDN services;
• edge-routing services;
• cloud-network connectivity.

Market definition must consider:

• latency;
• geographic coverage;
• redundancy;
• switching costs;
• capacity;
• technical compatibility;
• resilience.

35. Key Legal Questions

When investigating global routing infrastructure, regulators should ask:

1. Who controls the infrastructure?
2. What percentage of traffic depends on it?
3. Are alternatives realistically available?
4. Can competitors replicate the infrastructure?
5. Is access technically indispensable?
6. Are access conditions discriminatory?
7. Is the operator vertically integrated?
8. Does it compete downstream?
9. Does it favour affiliated services?
10. Are routing algorithms independently auditable?
11. Are security justifications objectively supported?
12. Do national regulations create artificial entry barriers?
13. Does routing control facilitate coordinated conduct?
14. Could disruption create systemic economic consequences?

36. Conclusion

Global Routing Infrastructure Control and Data Flow Governance represents an emerging competition-law problem at the intersection of telecommunications, digital markets, cybersecurity, data sovereignty and infrastructure regulation.

The principal concern is not routing itself. Rather, it is the possibility that control over routing becomes control over competitive access to the digital economy.

The traditional principles from AT&T, MCI, Bronner, IMS Health, Slovak Telekom and Deutsche Telekom remain particularly useful because they provide frameworks for analysing:

• infrastructure bottlenecks;
• indispensability;
• refusal to deal;
• discriminatory access;
• margin squeeze;
• vertical foreclosure.

Modern cases such as Google Shopping and Android extend the analysis toward ecosystem leverage and self-preferencing.

The central regulatory principle should therefore be:

Control over the physical and logical pathways through which data flows should not be allowed to become an invisible mechanism for controlling competition in downstream digital markets.

In the future, competition law will increasingly need to examine not merely who owns data or platforms, but who controls the pathways through which data, users, transactions and digital services reach one another.
