    In this paper congestion control over different time scales has been investigated to support data transport over a switched optical packet LAN. An innovative local access control protocol has been designed to shape different traffic sources to produce smoothed optical packet traffic which has a constant inter-arrival time. This protocol employs a centralized scheduling and resource allocation scheme, coupled with congestion control distributed to the edges. To cope with bursty traffic the network utilizes a feedback-based technique to implement service re-negotiation. This congestion control in the lower network layers operates synergistically with the TCP window-sized end-to-end admission control to deliver good traffic management and network efficiency. Network models have been built and the simulations carried out to validate the research and evaluate the network performance.
