End-to-end jitter analysis in networks of periodic flows
Kazem Sohraby, A. Privalov · 1999
Constant bit rate (CBR) traffic is expected to be an important traffic source in high-speed networks. Such sources usually have stringent delay and loss requirements and in many cases they should be delivered exactly as they were generated. A simple delay priority scheme in the network nodes will bound the delay and delay jitter for CBR traffic so that the CBR flows with stringent QoS will only compete with similar traffic flows within the network. We extend the work of Privalov and Sohraby (see IEEE/ACM Trans. on Networking, 1998) to a networking environment and provide the end-to-end jitter analysis of feed-forward connection-oriented networks supporting multiplexed CBR connections. The impact of the traffic mix in each node and the number of nodes in the network on the end-to-end jitter of individual flows are examined.
