| Abstract: | With the development of power optical transmission network, the network structure is more and more big, more and more complex, according to the common network faults and existing survival technology, combined with the development needs of network survivability, we analyze 1 ＋ 1 and 1： 1 linear protection and P-Cycle protection scheme, and describe the protection and restoration of OTN network. With the rapid development of grid service, IP service presents the fast growth, the protection ofOTN multi domain network restoration has become a hot topic. |
