NANOG 12 (Albuquerque): Speaker Abstracts

The North American Network Operators Group (NANOG)


Abstracts of February 1998 NANOG presentations appear below. This isn't a complete list - other summaries will be added in the coming weeks. Stay tuned! 

Recent Events in Inter-Provider Multicast (Dave Meyer, Univ. of Oregon)
The advent of BGP4 (multi-protocol BGP-4) has enabled rational inter-domain multicast routing. This talk reports on the new technology, transition stragegies from the existing MBone, and related ongoing projects.

SprintLink Backbone Architecture Evolution: IP Over Sonet 
(Ted Studwell, Vab Goel, and Jian Li, Sprint)
Describes aspects of SONET Protection Switching, including 1:1 fiber backup capacity for backbone circuits and IP packet switching at Oc-12 line rates.

Massively Parallel Routing
(Vadim Antonov and David Bernstein, Pluris)
Today's demand for backbone speed is outpacing conventional routing technologies. Projections show that the Internet will reach the terabit-per-second threshold in just a few years, and Internet Service Providers, especially backbone operators, will need to run networks using advanced routers that can support up to terabit performance. Conventional router manufacturers as well as other startups in the gigabit and terabit routing technology arena hope to rely simply on faster electronics. 

Although aggregate data rates of Internet traffic are skyrocketing, the bandwidth of individual communication sessions remains relatively small (in fact, this bandwidth cannot grow faster than the performance of host computers). Antonov believes that terabit-level aggregate routing capacity can be achieved by distributing the paths of packets in those connections between a large number of medium-performance routing engines interconnected using massively parallel packet routing architecture. Massively parallel routing technologies will transcend the power of conventional technology by as much as 4 orders of magnitude (10,000 times) by making large numbers of routing engines work in parallel.

A Route-Filtering Model for Improving Global Internet Routing: An IOPS Proposal 
(Jessica Yu, ANS)
The proposed model, if implemented by ISPs, will help reduce, if not eliminate, the injection of bad routing information into the Internet routing system. It can also help prevent incidents such as the intentional injection of unassigned addresses into the routing mesh for the purpose of sending spam.

Next-Generation NAS Architecture for Predictable and Reliable Network Access Services
(Shuang Deng, Aptis)
Users and operators are increasingly demanding predictable and reliable network access server (NAS) solutions. Many NAS products were designed for the enterprise market, and cannot scale up to today's Internet. Some high-density NAS products were designed with Internet access in mind, but have exhibited various scalabilty and performance problems. Meanwhile, the user community and the general public have begun to pay attention to network performance - both backbone and access included. In this presentation, we will examine the architecture of existing NAS solutions and identify the performance and reliability implications of various design decisions. A new architecture will be presented as the next-generation of true carrier-class access service that promises to meet the performance and reliability requirements of business and large-scale consumer applications.
