Tony Bates
1991 – Self-taught network engineer from West London who helped carry Britain’s academic network onto TCP/IP, helped build Europe’s IP registry at the RIPE NCC, co-authored the multiprotocol BGP extensions still routing the Internet, and created the CIDR Report that policed the global routing table’s growth.
Summary of Contributions (50 words)
Tony Bates helped run the UK end of the ARPANET gateway, helped move JANET from Coloured Book protocols to IP, joined the RIPE NCC’s founding effort on Europe’s address registry and routing registry, co-authored RFC 2283 and RFC 4760 on multiprotocol BGP, and originated the CIDR Report.
Impact (200 words)
Bates’s impact runs through the plumbing that let the Internet scale across borders and address families. A hairdresser’s son from Teddington who dropped out of South Bank Polytechnic, he taught himself C and Unix on the commute to the University of London Computer Centre, where from 1986 he operated international links including the ARPANET gateway between the United States and the United Kingdom. He then helped move JANET, Britain’s academic network, off its X.25 Coloured Book protocols and onto TCP/IP through the JANET IP Service, the transition that put an entire nation’s universities onto the Internet’s protocol suite.
In 1992 he moved to Amsterdam to work on the RIPE NCC effort, building the registry infrastructure through which Europe’s IP addresses and routing policies were recorded, including the routing registry work that became RPSL, RFC 2622, of which he is a co-author. He co-wrote RFC 1930, the guidelines for creating and registering Autonomous Systems, and at MCI in Virginia began the CIDR Report, the weekly public accounting of routing table growth and aggregation that pressured every operator on earth toward address discipline.
At Cisco he co-authored RFC 2283, later RFC 4760, Multiprotocol Extensions for BGP-4, the mechanism that lets one BGP carry IPv6, VPNs, and more.
Influence (200 words)
Bates’s influence works through instruments of coordination rather than decree. The CIDR Report was a social technology disguised as a statistics page: by publicly ranking the networks announcing the most unaggregated routes, it made routing table hygiene a matter of visible reputation, and the global table’s survivable growth through the 1990s owes something real to that weekly pressure. The routing registry and RPSL work gave operators a shared language for publishing routing policy, the basis on which peers could filter, verify, and trust one another’s announcements.
The multiprotocol BGP extensions carry his influence forward structurally. RFC 2283 and its successor RFC 4760 made BGP address-family agnostic, which is why the Internet did not need a new routing protocol for IPv6, and why MPLS VPNs, multicast routing, and EVPNs all ride today on the same BGP sessions. Nearly every service provider network on earth runs configurations descending from that design.
His influence extends across:
- global routing table discipline, through the CIDR Report
- inter-provider trust and filtering, through the routing registry and RPSL
- AS number practice, through RFC 1930
- IPv6 and VPN deployment, through multiprotocol BGP
- the UK’s Internet transition, through JIPS
- Europe’s address administration, through the RIPE NCC’s early build-out
Reach (200 words)
Bates’s reach spans every BGP session carrying more than plain IPv4. Multiprotocol BGP is implemented in every serious router operating system, and the extensions he co-authored are the vehicle for IPv6 routing, layer 3 VPNs serving enterprises worldwide, and much of the modern data center fabric. The routing registries he helped design still operate: the RIPE database and its sibling registries on other continents remain the reference infrastructure for routing policy on tens of thousands of networks.
His earlier work reaches everyone who used a British university network after 1991, when JANET’s IP service opened the country’s academic community to the Internet proper, and everyone whose addresses were allocated through the European registry system he helped stand up in Amsterdam.
His reach extends through:
- every IPv6 route and MPLS VPN announced via multiprotocol BGP
- the RIPE NCC, now serving thousands of member networks across Europe, the Middle East, and Central Asia
- routing registry data used daily for filter generation worldwide
- decades of CIDR Report editions read by the global operator community
- JANET’s IP transition, ancestor of UK Internet access at scale
His later executive arc, fourteen years at Cisco rising to senior vice president, CEO of Skype through its 8.5 billion dollar sale to Microsoft, president of GoPro, chairman and CEO of Genesys, carried a routing engineer’s sensibility into the industry’s boardrooms.
Innovation (200 words)
Bates’s innovations include:
- co-authorship of RFC 2283 and RFC 4760, Multiprotocol Extensions for BGP-4, with Chandra, Katz, and Rekhter
- the CIDR Report, public measurement as an instrument of routing table governance
- co-authorship of RPSL, RFC 2622, and the routing registry practice behind it
- RFC 1930, with John Hawkinson, the guidelines governing Autonomous System creation and registration
- the JANET IP Service transition, moving a national network between protocol worlds without stopping it
The multiprotocol BGP work is the deepest cut. In the mid-1990s the obvious path was a new routing protocol for each new address family, an operational nightmare multiplied across every provider. The Bates, Chandra, Katz, and Rekhter design instead made the existing protocol carry arbitrary address families as attributes, preserving BGP’s deployed base, its operational knowledge, and its peering relationships while opening it to everything that came next. Thirty years on, no successor has been needed.
The CIDR Report deserves equal note as a governance invention: no authority could order independent networks to aggregate their routes, but a trusted weekly measurement, naming names, could shame them into it. Measurement as regulation, registry as trust fabric, one protocol made extensible instead of many: that is infrastructure statesmanship performed in engineering documents.
