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.
