VIRTUALIZATION BASED DYNAMIC CIRCUIT NETWORK ARCHITECTURE FOR EFFICIENT PATH COMPUTAION

摘要

PURPOSE: A system and a method for offering efficient route computation between virtualization-based domains in a dynamic circuit based-network are provided to configure various DCNs(Digital Cellular Networks) with one system without purchasing computer for a plurality of NARBs(Network Aware Resource Brokers). CONSTITUTION: A virtualization-based NARB/RCE(Resource Computation Element)(131,132) administrates VLSRs(Virtual Label Switched Path)(111~113,121~123). A virtual bridge connects the NARB/RCE with a network. The VLSR offers mechanism for integrating non GMPLS(Generalized Multi-Protocol Label Switching) equipment and provided services to a network domain. The VLSR configures network topology for a corresponding domain. The network topology of each domain is transmitted to a corresponding to NARB/RCE.
