New applications are likely to ask for a more flexible bandwidth, large bandwidth for limited amount of time. In order to meet these new requirements, flexible optical transport networks in which connections could be set up and released on dynamic short-term basis have to be introduced. We propose a distributed Holding-Time-Aware provisioning framework based on intelligent destination routing to assign...
In transparent optical mesh networks, different protection schemes can be used to satisfy the service availability against network failures. However, in order to satisfy a connection's service availability requirement in distributed controlled optical networks with no global information, we need a framework to provision a working path with the appropriate level of protection for each connection request...
In optical mesh networks, different protection schemes can be used to satisfy the service availability against network failures. However, in order to satisfy a connectionpsilas service-availability requirement in a distributed controlled WDM with dynamic traffic and no wavelength converters, we need a framework to manage the provisioning process and to select a proper protection scheme. In this paper,...
This paper presents a novel shared protection framework for online provisioning in distributed controlled survivable wavelength-division multiplexed (WDM) mesh networks. This framework contains two integrated protocols. The protocol is the signaling technique that probes each path as both a candidate working path and a candidate shared protection path at the same time. The second protocol is the routing...
This paper presents a novel distributed protocol for online provisioning in survivable mesh-based wavelength-division multiplexed (WDM) networks. This protocol examines each of the k link disjoint shortest paths as a candidate working path and as a candidate shared protection path at the same time, in parallel which gives the destination node the ability to apply an intelligent adaptive routing and...
