Internet Capacity Sharing: Fairer, Simpler, Faster?

The idea that TCP shares out Internet capacity fairly is a dangerous myth. The same applies to fair queuing. The danger? While we continue to pretend that wildy unfair solutions are fair enough, Internet service providers increasingly override them with kludges like deep packet inspection. Then the Internet gradually snarls up with bizarre feature interactions. This talk offers a path out of this cul de sac, solving multiple problems at once, including:

  • Fair capacity sharing that is robust against self-interest and malice;
  • Shifting to a performance regime that will continue to scale
  • Taking account of the interests of each stakeholder (?)
  • Simplicity

Strategic changes to host network stacks are central to the story. The talk will end with time to discuss: “Would Microsoft set aside development effort to revisit these fundamentals?”

Speaker Details

Bob Briscoe is Chief Researcher in BT’s Networks Research Centre and leads research in BT’s Future Communications Architecture programme. He joined BT in 1980 attaining a degree in engineering from the University of Cambridge in 1984, specialising in economics and industrial sociology. Through part-time study, in 2009 he attained a Computer Science PhD from UCL. The thesis concerned freedom with accountability on the Internet. In the late-1980s he managed the transition to IP of many of BT’s R&D networks and systems. In the mid-1990s he represented BT on the HTTP working group of the IETF and in the ANSA distributed systems research consortium, which led to the creation of the OMG and CORBA. In 2000 he initiated and was technical director of the Market Managed Multi-service Internet (M3I) consortium, a successful European collaboration that solved the problem of controlling Internet quality using dynamic wholesale pricing, but with flat retail pricing. He also helped incubate Qariba, an on-demand bandwidth start-up that was ultimately re-absorbed into BT to form BT’s new Internet access products. In 2003 he initiated the Communications Research Network (CRN), a collaborative initiative to remove technical, commercial and regulatory blockages to the future health of the communications industry. He also continues to be heavily involved in standardizing research results, mainly through the IETF. His published research, standards contributions and patent filings are in the fields of Internet architecture, loosely coupled distributed systems, scalable network QoS, group security &charging solutions, managing fixed and wireless network loading using pricing, denial of service resistance, the economic structure of communications markets and lately slaying myths about network economics.
