OPS (optical packet switching) is a promising technology for high-speed networks. In this paper, impact of ingress packet size on QoS (quality of service) of survivable networks is investigated. DV (distance vector) and LS (link state) dynamic routing techniques are applied to ensure survivability. Analysis is performed on 10-, 50-, and 100-node mesh networks for ingress packet size of 500, 1000, 1500, and 2000 bytes. Using the results obtained, it is observed that maximum percentage deviation of 2.45% in average E2E (end-to-end) delay and 14.71% in average jitter is obtained with respect to packet size variation in the network with 10 nodes and DV routing. As network size increases, average E2E delay and jitter variation with packet size are reduced. Throughput is almost constant with packet size variation under DV routing. This framework provides deep understanding about impact of network and packet size on QoS of high-speed networks.
