摘要
介绍了弹性分组环异步网络中发送速率同步功能的特点和实现同步的方式·结合弹性分组环环网中的带宽分配原则提出了一种能够适用于弹性分组环异步环网的同步传输机制:动态加权发送速率·该机制依据节点主传送队列深度动态改变接收数据流的转发权值来实现同步传输·研究结果表明该机制能够实现弹性分组环异步环网中的同步传输,节点主传送队列不会溢出·
The characteristic and method of the synchronous transmitting function in RPR asynchronous network was introduced. Then a new synchronous transmitting mechanism for RPR asynchronous network according to the principle of allocating bandwidth was proposed. The new mechanism was named as Dynamic Weighted Transporting Rate. The synchronous transmitting wass based on dynamic altered transmitting weight of the received data stream according to the PTQ depth. Simulation results show that the mechanism can achieve synchronous transmitting in RPR asynchronous network, and the PTQ will not overflow.
