Architecting an Evolvable Internet with XIA

1 Apr

John Byers, Professor of Computer Science & Fellow of the Rafik B. Hariri Institute for Computing and Computational Science & Engineering, Boston University, USA

External Presentation (External Speaker)

Motivated by limitations in today’s host-centric IP network, several recent “clean-slate” network architectures have proposed alternate first-class principals, such as content, services, or users. However, much like the host-centric IP design, elevating one principal type above the rest hinders communication between other principals and inhibits the network’s capability to evolve. In this talk, we present the design philosophy, prototype Linux implementation, and applications of the eXpressive Internet Architecture (XIA) that we have developed in a large collaboration between CMU, BU, and U. Wisconsin.  Focusing on the XIA data plane, we show how XIA’s addressing and forwarding semantics support multiple principals in tandem, facilitating flexibility yet keeping core network functions simple, secure, and efficient.  We then demonstrate XIA’s ability to evolve, by describing our experiences porting several distinct and unrelated network architectures onto Linux XIA, notably NDN and Serval, neither of which were designed for interoperability with our platform.

John Byers is a Professor of Computer Science at Boston University, where he joined the faculty in 1999 after completing his Ph.D. at U.C. Berkeley. He is also Chief Scientist and a member of the Board of Directors at Cogo Labs (formerly Adverplex, Inc.), a quantitative online advertising firm based in Cambridge, MA, where he has held an executive role since the company’s founding in 2005. Professor Byers’ research interests are broadly focused on algorithmic and economic aspects of networking, e-commerce and large-scale data management. He received the ACM SIGCOMM Test of Time Award in 2009 for his work on scalable loss-resilient multicast, the IEEE ICDE Best Paper Award in 2004 and the ICDE Influential Paper Award in 2014 for his work on sensor databases, and a National Science Foundation CAREER Award. He served terms on the editorial board of IEEE/ACM Transactions on Networking and on the executive committee of ACM SIGCOMM. He was co-chair of the ACM SIGCOMM ’11 Technical Program Committee and General Co-Chair for the 2012 ACM Internet Measurement Conference held at Boston University.
