Abstract

The use of EPON for network allocation is gradually becoming the main stream for broadband network. This technology makes full use of the features of optical network and passive optical splitter to reduce equipment costs, operation and maintenance costs for network operators and to provide faster and more stable broadband network for users. The article introduces the working principle of EPON, establishes EPON system based on OPNET technology, analyzes the current bandwidth allocation algorithm, and proposes improvement to the algorithm. Experimental emulation finds that the new algorithm can provide good QOS service and is greatly improved in the aspects of packet delay, average queue and bandwidth utilization rate.
