Study on survivability mechanism of military optical fiber communication transmission network

摘要

Survivability and survivability mechanism of military optical fiber communication transmission network were studied. Three protection modes were discussed in detail and channel/link based restoration mechanisms were compared. Lastly, a harmonization strategy including the lower layer principle, fault type based restoration and selective protecting idle capacity design, was proposed to improve the network survivability. Experimental results show an improved survivability and a higher utilization ratio of the network resources than the traditional protecting approach.
