Abstract :
The performance of optical networks which carry traffic with a wide range of requirements is greatly influenced by the scheduling disciplines present in the routers and switches. In this work performance of scheduling disciplines like FIFO (first in first out), PQ (parity queuing), WFQ (weighted fairness queuing), MWRR (multiclass weighted round robin), CQ (custom queuing) and DWRR (deficit weighted round robin) in packet dropping and reception for a high speed network is simulated. OPNET IT GURU a network simulator from OPNET Technologies has been used for simulation. It has been observed that PQ, WFQ, MWRR, DWRR perform alike in dropping packets. The bursty nature of WFQ doesn´t make it to receive any voice traffic over all intervals of time. Regarding video conferencing traffic a sharp fall in received data was observed for PQ and CQ
