Abstract

Optical buffering is one of the main obstacles in optical packet switching (OPS) networks. We proposed the network global control strategy to resolve this problem. By introducing the cycled traffic at the edge node and the slot assignment algorithm at the core node, a slotted OPS networks with no contention can be realized. In this network, a good throughput, end to end delay and delay jitter performance can be gotten at high load simultaneously, so it may be a promising candidate for the future optical networks.
光分组交换网络中基于网络全局控制的争用解决
光缓冲是实现光分组交换(OPS)网络的主要障碍之一。为了解决这一问题,我们提出了网络全局控制策略。通过引入边缘节点的循环流量和核心节点的槽位分配算法,可以实现无争用的分槽OPS网络。该网络可以在高负载下同时获得良好的吞吐量、端到端时延和时延抖动性能,是未来光网络的理想选择。
