Abstract

Passive Optical Network (PON) is a crucial access network which is widely deployed in modern society. With the development of network convergence, PON carries many differentiated services from not only the Internet, but also the telecom, TV broadcasting and smart grid. However, there exists different Quality of Service (QoS) requirements for the different services and it challenges our network on both the routing strategy and network management. Aiming at achieving load balance when there exists multiple services on network, we propose HTA-ToS algorithm, which provides load-balanced routing strategy for every type of service (ToS) while discriminating them according to their QoS requirements in routing process. To verify our algorithm, we design the scheme and implement it in the software defined network (SDN) controller Floodlight. The results show that the algorithms can improve the efficiency of load balance, and fulfill the QoS requirements of ToS to some extent.
