This paper evaluates power efficiency of TE link dormant mode in optical transport network, considering daily traffic variability and GMPLS protocol. The proposed TE link dormant mode tries to let data links comprised the TE link transfer into the dormant state according to several selection criteria considering either the power consumption parameter of each link and their positioning in the network...
Pre-configured protection cycles (p-cycles) have drawn many attentions due to the fully pre-connected cyclic structures, ring-like speed, mesh-like spare capacity efficiencies and fast switching characteristics. In this paper, we propose a novel removal of loop back (RLB) approach with standard protocol extension (the flooding based distributed cycle pre-configuration (F-DCPC)) to solve the resource...
Generalized Multi-Protocol Label Switching (GMPLS) based optical networks are viewed as a promising network infrastructure for the next generation network (NGN) development. By pre-configuring the resources of dynamic optical networks, we can reconstruct the physical topology, thus increase the number of direct routes between potentially heavily loaded physical node pairs and optimize the performance...
As most of the carriers have extended their circuit transport networks with packet transport capabilities due to the inefficient transport network architecture, the controlling manner developed silently. Multiple service transport platform is the newly proposed packet based transport technology and the standardization process is very fast. GMPLS is considered to be the future controlling technologies...
As the scalability of network grows rapidly, multiple carriers can interoperate under a common control plane and operate separately. A large network is often composed of a lot of network nodes which incurs great burdens for network management and controlling bandwidth spending. Networks comprised of LSRs with different data plane switching layers controlled by a single GMPLS control plane instance...
