Latency Analysis of TCP on an ATM Network

In this paper we characterize the latency of the BSD 4.4 alpha implementation of TCP on an ATM network. Latency reduction is a difficult task, and careful analysis is the first step towards reduction. We investigate the impact of both the network controller and the protocol implementation on latency. We find that a low latency network controller has a significant impact on the overall latency of TCP. We also characterize the impact on latency of some widely discussed improvements to TCP, such as header prediction and the combination of the checksum calculation with data copying.

An experimental study of VBR video over various ATM switch architectures

One of the most important components of an Asynchronous Transfer Mode (ATM) network is the switch. Switch design is not a part of the ATM standards so vendors use a wide variety of techniques to build their switches. In this paper, the authors present experimental results of switching and multiplexing real-time Variable Bit Rate (VBR) video traffic (JPEG, MPEG-1, and MPEG-2) through two different ATM switch architectures. Real-time VBR traffic, such as digital video, is particularly interesting due to its high demands in terms of bandwidth, real-time delivery and processing requirements. The experiments show that the fastest switches, i.e., lowest latencies, do not necessarily perform better when transmitting VBR video. The impact of the high speed network components; characteristics, such as switch fabric architecture, buffering strategies, and higher layer transport protocols (i.e., UDP, TCP/IP), are illustrated through the experimental results
