Sizing Router Buffers for Large-Scale TCP/IP Networks

Abstract (in Japanese) (See Japanese page) 
(in English) We investigate the validity of reducing core router buffer size in a
large-scale network that includes both core networks and edge
networks. We have presented a novel mathematical analysis method of
estimating the average behavior of TCP connections in a network with
100/1,000/10,000 routers/endhosts/links and 100,000 concurrent TCP
connections. By applying our analysis method to the Abilene-inspired
network, we demonstrate the influence of small buffer on link
utilization, packet loss ratio and the performance of TCP connections
passing through the router. One important result is that, especially
when the edge network becomes faster, decreasing buffer size at core
routers causes unfairness between TCP connections that traverse the
core network and those do not traverse the core network.
