The block on the hotel rooms ends Wednesday, 5/6. Be sure to reserve your room. All attendees need to register via the website, if you are unable to do this please contact me. The attendee list is current. The following is the agenda so far: SUNDAY AFTERNOON TUTORIAL: Introduction to RPSL (Cengiz Alaettinoglu, ISI, Curtis Villamizar, ANS) Find out about Routing Policy Specification Language, which will succeed RIPE-181 as the language used to express policy in the Internet Routing Registry. A description of the tutorial is available HERE. SUNDAY EVENING TUTORIALS Introduction to Multicast (Dave Meyer, Cisco) Interesting Things You Can Do With OSPF (Howard Berkowitz) After an introductory overview of the OSPF interior routing protocol, Berkowitz presents some interesting case studies of useful but non-obvious things one can do with OSPF, if one is willing to think "outside the box." The tutorial concentrates on determining requirements and network design, rather than detailed configuration, emphasizing ways that a high-powered OSPF domain can be a viable alternative to BGP for many customer and internal ISP applications. Also includes information about practical address management with OSPF. QoS and Ebone: Issues and Potential Solutions (Sean Doran, Ebone) Discussion of RED/QoS issues for the Ebone. Click here for a detailed overview of the talk. Network-based Denial of Service Attacks: Descriptions and How to Protect Your Network (Craig Huegen, Cisco) Recommendations on Queue Management and Congestion Avoidance in the Internet (Van Jacobson, Lawrence Berkeley National Laboratory) What Is a VPN? (Paul Ferguson, Cisco Systems) Definition of Virtual Private Networks and overview of approaches to building VPNs. Read the paper, by Ferguson and Geoff Huston, HERE. Dial-in VPN Using Layer 3 Tunneling (Gary Malkin, Bay Networks) Review of the Virtual Private Networking topology and problem space, overview of encapsulation and tunneling, and Bay Networks's DVS solution. Broadband VPNs - Outsourcing ISP services to Cable TV and XDSL Providers (Bruce Perlmutter, Bay Networks) Data over cable TV and xDSL are technologies that are experiencing enormous growth as a means to provide high speed Internet access to consumers. Most implementations of these technologies require the cable provider to become an Internet Service Provider (ISP) - a business for which they are often ill prepared. This presentation describes an architecture that allows cable providers to outsource the ISP function to a number of partner service providers. The cable provider installs and manages the physical plant, and bills the customer for services (voice, video, data) delivered over this plant. Data traffic from these customers arrives at the cable provider head end and is routed to an Internet Service Provider (or other data network) selected by the customer. Even though the customers are connected to a common access infrastructure (XDSL or cable TV), they appear as though they are connected only to their selected ISP. This approach can be called a Virtual Private Network. Issues discussed include: IP address allocation and packet routing, accounting and authorization mechanisms, and encryption and privacy issues. Roadmap to a Distributed Registry: Transition to RPSL (Routing Policy System Language) (Cengiz Alaettinoglu, ISI, Curtis Villamizar, ANS) Differentiated Services Panel: Working Group Update and Viewpoints From the Community (Kathleen Nichols, Bay Networks, moderator; Van Jacobson, Lawrence Berkeley National Laboratory, Fred Baker. Cisco, Peter Ford, Microsoft Building Large-Scale Internet Measurement Infrastructure (Vern Paxson, Lawrence Berkeley National Laboratory) Scaling and Other New BGP Features (Mark Turner, Cisco) Recent work on BGP scaling issues, including support for peer groups over multiple IP subnets, prefix lists, neighbor route count limits, and Cisco Express Forwarding/QoS interactions. ARIN Update (Kim Hubbard, ARIN) InterNIC Update (Mark Kosters, InterNIC) Path and Round-Trip Time Measurements: a New Project at CAIDA (Daniel McRobb) Implementing Simplex IP Bandwidth Augmentation and IP-Based News and HTTP Broadcast Services via Geosynchronous Satellite (Avi Freedman, Net Access) Covers details of implementing half-duplex satellite bandwidth augmentation and news/web cache broadcast over satellite. Net Access does all three on one signal; for bandwidth augmentation, a Cascade-based solution and a Cisco IP-tunneling-based solution will be presented. Introduction to the NETPERF.NET Inter-Provider Network Performance Monitoring Project (Avi Freedman, Net Access) Sponsored by Net Access, the project deploys pairs of servers (one web server, one query box) at each provider being studied, and generates semi-real-time NxN graphs of packet loss, latency, and throughput between the various providers.
