Efficient distributed path selection for shared restoration connections
TL;DR: This work proposes an efficient path-selection algorithm for restoration of connections over shared bandwidth in a fully distributedGMPLS architecture and describes how to extend GMPLS signaling protocols to collect the necessary information efficiently.

Method for selecting a restoration path in a mesh network
TL;DR: In this paper, a method of selecting a restoration path in a mesh telecommunication network is disclosed that advantageously is practical and flexible and may be pre-computed along with a service connection path during the setup of the connection.
Journal ArticleDOI
Control plane design for reliable optical networks
TL;DR: A detailed discussion of a number of subtle protocol design and implementation issues that were not addressed in early standardization efforts or published papers are provided.
Proceedings ArticleDOI
Fair and optimal resource allocation for LTE multicast (eMBMS): Group partitioning and dynamics
TL;DR: The tradeoff between improving unicast user rates and improving spectrum efficiency through multicast is demonstrated and it is shown that even if the user deviates from the global solution in a number of scenarios, the number of selfish users that will choose to deviate is bound.
