Interlink (network) is a global meshed packet-switched infrastructure conceived to interconnect heterogeneous access domains, backbone carriers, and cloud providers. It emerged from collaborations among legacy carriers, startup exchanges, and standards bodies to provide high-availability peering and transit across metropolitan, national, and submarine segments. Interlink positions itself at the intersection of legacy telephony, Internet exchange fabrics, and content delivery ecosystems, aiming to bridge disparate routing, signaling, and policy regimes.

Overview

Interlink traces conceptual lineage to initiatives like the Internet Protocol Suite, Border Gateway Protocol, and regional exchange points such as the AMS-IX, LINX, and DE-CIX. Early deployments referenced technologies standardized by the IETF, specifications from the IEEE, and recommendations from the ITU. Its governance model drew on multistakeholder frameworks exemplified by the Internet Society and the World Wide Web Consortium, while operational practice incorporated lessons from Level 3 Communications, AT&T, NTT Communications, and neutral host operators such as Equinix and Digital Realty. Strategic partners have included content platforms like Netflix, cloud providers such as Amazon Web Services, Google Cloud Platform, and Microsoft Azure, and transit carriers like Cogent Communications.

Architecture and Components

Interlink's architecture uses layered fabrics combining carrier-grade switching arrays, route reflectors, and software-defined control planes influenced by OpenFlow and Segment Routing. Core components include metropolitan aggregation nodes, submarine cable landing stations similar to Marea and FASTER, PoP sites co-located at data centers operated by Equinix, and edge caches akin to Akamai deployments. Control elements reference designs from Juniper Networks, Cisco Systems, and open-source projects such as FRRouting and Quagga. Management stacks integrate orchestration frameworks like Kubernetes for VNFs, configuration tools inspired by Ansible and SaltStack, and telemetry inspired by NetFlow and sFlow. Interconnect agreements parallel models used by PeeringDB, bilateral arrangements seen at LINX, and multilateral IX frameworks comparable to Euro-IX.

Protocols and Standards

Interlink implements routing based on extensions to Border Gateway Protocol with route-policy templates and flow-spec adaptations used by carriers including Verizon and BT Group. For service chaining and VPN overlays it adopts Multiprotocol Label Switching and Virtual Extensible LAN semantics, and leverages Resource Reservation Protocol in specialized enterprise slices. Control and orchestration utilize APIs aligned with Representational State Transfer practices, while security and keying incorporate standards from IETF RFCs and IEEE 802.1X for port-based network access. Transport sections have employed MPLS-TP trials, Carrier Ethernet profiles defined by the Metro Ethernet Forum, and timing sync tied to Precision Time Protocol used in financial exchanges like NASDAQ. Interlink’s telemetry conforms to formats championed by OpenConfig and monitoring paradigms deployed by platforms such as Prometheus.

Deployment and Use Cases

Operators deploy Interlink in contexts ranging from content delivery acceleration for platforms like Spotify and YouTube to low-latency financial trading corridors connecting exchanges such as NYSE and CME Group. Enterprises use it for hybrid cloud interconnects between campuses and cloud regions of Oracle Cloud and Alibaba Cloud, and public sector agencies have piloted implementations for disaster-resilient communications modeled after systems used by Red Cross and FEMA. Mobile network operators including Verizon Wireless and Vodafone have experimented with Interlink for mobile backhaul and 5G fronthaul scenarios akin to initiatives by 3GPP and GSMA. Research networks such as Internet2 and GEANT have also engaged in testbeds to validate multicast and high-bandwidth science flows similar to collaborations with CERN and LIGO.

Performance and Scalability

Interlink emphasizes metrics familiar to carriers and hyperscalers: throughput observed in terabit-scale trunks akin to deployments by NTT and CenturyLink, jitter and latency comparable to microwave corridors used by Xetra traders, and availability SLAs paralleling those of Cloudflare and Fastly. Scalability strategies include hierarchical route distribution resembling practices at Amazon backbone, traffic engineering via SDN controllers inspired by ONOS and OpenDaylight, and elastic capacity achieved through virtualized network functions as seen in NFV rollouts by Deutsche Telekom. Benchmarking exercises often reference testbeds created by ETSI and performance studies published by IEEE Communications Society.

Security and Privacy

Security posture in Interlink integrates measures adopted across major operators: prefix filtering and RPKI validation advocated by the IETF and deployed by registries like ARIN, RIPE NCC, and APNIC; DDoS mitigation techniques employed by Akamai and Cloudflare; and encryption for control planes drawing on IPsec and TLS implementations used by OpenVPN and WireGuard. Privacy controls follow consent and data-handling practices referenced in regulatory regimes such as the European Union directives and interactions with authorities like FCC in the United States. Incident response aligns with frameworks from FIRST and coordination channels used by US-CERT and national CERTs. Policy debates involve stakeholders including ICANN, the OECD, and national ministries of communications.
