ISMA Dec '01 Routing and Topology Analysis
On December 17-19, 2001, CAIDA will host an Internet Statistics and Metrics Analysis (ISMA) workshop concerning the analysis of core routing tables and macroscopic topology data sets. This meeting is intended for researchers and practitioners experienced in data analysis, data visualization, and Internet operations fields.

Workshop Research Questions

  • How accurately does a typical core routing table reflect paths that traffic will actually take through the infrastructure? Can we account for all types of incongruities?
  • What causes routing table growth? What data supports or refutes previous or current assumptions? Is routing table growth scalable? Does table growth correlate to table churn?
  • What options are available for route filtering at boundaries and how do they impact routing system architecture? What are potential effects of filtering announcements from peers on RIR allocation boundaries? Does implementing such a policy potentially penalize providers who conserve address space and/or utilize NAT?
  • How can multihoming be provided at an equitable cost to those customers who benefit from it? Are measures to restrict sizes or frequency of route announcements from multihoming sites warranted?
  • Can we accurately characterize BGP convergence times? What is the best we can expect from BGP?
  • What is the impact of denial-of-service (DoS) and other security attacks on the routing system? What countermeasures are possible?
  • What routing paradigm supports forseeable Internet growth? Is a new routing system needed? If so, when? What are its requirements?
  • Have we figured out what the Internet "looks" like yet? When do we really need to model the Internet versus simulating generic types of networks?
