MAE-East

MAE-East. The Metropolitan Area Ethernet East, commonly known as MAE-East, was a foundational Internet exchange point established in the early 1990s. It served as a critical interconnection hub for Internet service providers and network service providers, facilitating the exchange of Internet traffic primarily on the East Coast of the United States. Its creation and operation were pivotal during the period of commercialization of the Internet, helping to shape the modern Internet backbone infrastructure.

Overview

MAE-East was one of the original major Internet exchange points in the United States, operated by MCI Communications. It was strategically located in the Washington, D.C. metropolitan area, a key nexus for telecommunications and federal government networks. The facility enabled disparate autonomous systems to peer directly, bypassing the NSFNET backbone as the Internet transitioned from a government-academic project to a commercial entity. Alongside its counterpart MAE-West in California, it formed the backbone of early North American Internet infrastructure.

History

MAE-East was established in 1992 by the MCI subsidiary MFS Communications Company, initially as a FDDI ring. Its creation was a direct response to the evolving needs of the Internet following the Acceptable Use Policy of the NSFNET, which restricted commercial traffic. Key early participants included UUNET, PSINet, and SprintLink, who sought efficient ways to exchange data. The exchange grew rapidly, becoming a congested but vital choke point, famously described as the "Grand Central Station" of the early Internet. Its operational history reflects the broader history of Internet governance and the shift toward private peering agreements, eventually leading to its decommissioning in the late 1990s as newer, more distributed exchanges like Equinix and MAE-LA emerged.

Technical specifications

The original MAE-East implementation utilized a FDDI ring operating at 100 Mbit/s, a standard championed by the ANSI. This shared media architecture, while revolutionary for its time, became a significant bottleneck as traffic volumes exploded. The physical infrastructure was housed in a MFS Communications Company facility, with connections to major carrier hotels and telecommunications conduits in the Washington, D.C. area. Network access was governed by specific technical policies and routing policies set by the operator, influencing the development of the BGP and practices documented in RFCs by the IETF.

Services and connectivity

MAE-East provided a neutral Layer 2 Ethernet switching fabric for public peering, allowing members to establish bilateral peering or participate in a multilateral peering arrangement. Its primary service was the exchange of IPv4 traffic, though it also carried early IPv6 experimental traffic. Connectivity was offered to a wide array of entities, including ISPs like GTE and Netcom, academic networks such as SURAnet, and commercial content providers. The exchange also facilitated connections to major transatlantic cables and other IXPs, indirectly linking to European hubs like LINX and AMS-IX.

Impact and significance

MAE-East played a decisive role in the commercialization of the Internet by providing a vital marketplace for Internet traffic exchange. Its operational challenges, including chronic congestion, directly informed the design of next-generation Internet exchange points and the evolution of Internet architecture. The exchange is historically significant as a case study in the transition from a centralized NSFNET model to a distributed, competitive Internet backbone ecosystem. It influenced key figures and organizations within the Internet Society and shaped early discussions on network neutrality and interconnection economics. Its legacy is evident in the global, robust mesh of modern Tier 1 networks and carrier-neutral facilities.
