基于信元交换的分组光传送网系统设计与实现
Design and implementation of cell switchingbased packet optical transport network systems
摘要
基于OIF (光互联论坛)协议标准,在业界首次建立了基于信元交换、能同时支持ODUk (k阶光通路的数据单元)交叉分组交换(交换容量大于10 Tbit/s)的POTN(分组光传送网)系统,并进行了实际测试。测试结果满足POTN系统的ODUk抖动、时延和误码要求,以及数据业务的丢包和时延要求,验证了该技术的可行性和实用性。
Abstract
On the basis of the Optical Internetworking Forum (OIF) protocol standards, we establish for the first in the industry a cell switchingbased Packet Optical Transport Network (POTN) system, which simultaneously supports the crossconnect and packet switching of the Optical Channel Data Unit k (ODUk) with a switching capacity of over 10 Tbit/s, and have it tested in practical projects. The test results indicate that this technology meet the requirements of POTN system in ODUk jitter, latency and bit error rate, and of data services in packet loss and latency, verifying its feasibility and practical applicability.
