Internet links operate at high speeds, and past trends predict that these speeds will continue to increase rapidly. Routers and Intrusion Detection Systems that operate at up to OC-768 speeds (40 Gigabits/second) are currently being developed. In this ...

Recently there has been renewed interest in circuit switching because of the ease of building very high capacity optical circuit switches. This poster studies the performance, as seen by the end user, of an Internet that uses circuit switching instead ...

This poster describes the results of a 500 million packet trace of a popular on-line, multiplayer, game server. The results show that the traffic behavior of this heavily loaded game server is highly predictable and can be attributed to the fact that ...

With increasing demand for multimedia applications, local area network (LAN) technologies are rapidly being upgraded to provide support for quality of service (QoS). In a network that consists of an interconnection of multiple LANs via bridges, the QoS ...

Most of the end-to-end congestion control schemes are "voluntary" in nature and critically depend on end-user cooperation. We show that in the presence of selfish users, all such schemes will inevitably lead to a congestion collapse. Router and switch ...

The current Internet infrastructure has very few built-in protection mechanisms, and is therefore vulnerable to attacks and failures. In particular, recent events have illustrated the Internet's vulnerability to both denial of service (DoS) attacks and ...

We propose and evaluate a passive measurement methodology that estimates the distribution of Round-Trip Times (RTTs) for the TCP connections that flow through a network link. Such an RTT distribution is important in buffer provisioning, configuration of ...
