We introduce structural transformations that allow simplifying a given network while preserving its original “bandwidth” and “routing” capabilities, transparently to specific allocations. We minimize a certain objective such as the aggregate capacity of network links, number of nodes, or number of links, in such a way that all the bandwidth that could be routed in the original network can also be...
This paper introduces a new implementation of Shared Segment Protection (SSP) in mesh communication networks, in which a novel Integer Linear Program (ILP) is proposed under a reduced amount of routing information. In particular, the scheme of Distributed Partial Information Management with Sufficient and Aggregated Information (DPIM-SAM) [1] will be adopted for trading the optimality with the reduction...
The Department of Electronic Engineering of Beijing Institute of Technology is integrating emerging interconnect technologies with other high-performance technologies to meet the demanding requirement of future, real-time signal processing applications. For next-generation, scalable, modular and adaptable signal-processing system, a universal, flexible and high-performance signal processing module...
This paper describes a new path computation model in Multi-protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. It introduces a path computation element (PCE), which is functionally separate from label switching routers (LSRs). The Path Computation Element (PCE) is an entity that is capable of computing a network path or route based on a network graph, and applying computational...
