OTN通道保护时间与路由器路由收敛时间的配合测试

Collaboration Measure of OTN Path Protection Time and Router Network Convergence Time

光传送网(OTN)虽然能够提供海量的带宽,但与数据网络设备(如路由器)互联时,如果OTN网络的通道保护时间与数据网的收敛时间不同,会导致2个网络的保护具有震荡性。为此,研究OTN设备与路由器互联互通时的保护时间及测试方法,以便找到解决震荡的应对方法。

Although Optical Transport Network can provide massive amounts of bandwidth, the protection convergence time of the OTN networks channel is not equal to the convergence time of the data network when a OTN is inter-connected to a data network equipment ,. e. g. a router, interconnected, thus leading to the oscillation of the protection for the two network. Therefore, we studied the protection time and its measure methods in the case of the OTN equipment being interconnected with routers.
