Identifying, translating and filtering shared risk groups in communications networks

摘要

A method, apparatus, and computer-readable storage medium are disclosed for processing shared risk group (SRG) information in communications networks. The method includes obtaining at least one SRG identifier by processing SRG information included in network information received at a first network layer from a second network layer, and processing the at least one SRG identifier using one or more operations configured to ensure that the SRG identifier is unique among a plurality of SRG identifiers. The apparatus includes a network interface adapted to receive network information comprising SRG information, a processor coupled to the network interface, and a memory coupled to the processor and adapted to obtain at least one SRG identifier by processing the SRG information and to process the at least one SRG identifier. The computer-readable storage medium is configured to store program instructions that when executed are configured to cause a processor to perform the method.

1. A method, comprising:
receiving network information from a network server layer at a network client layer, the network information comprising shared risk group (SRG) information, wherein
the network client layer and the network server layer are comprised in a communications network; obtaining at least one SRG identifier by processing the SRG information; and processing the at least one SRG identifier, wherein
the processing the at least one SRG identifier comprises one or more operations configured to ensure that the at least one SRG identifier is unique among a plurality of SRG identifiers,the plurality of SRG identifiers comprises the at least one SRG identifier, andthe processing the at least one SRG identifier comprises at least one of translating the at least one SRG identifier into at least one client-layer SRG identifier, filtering a plurality of server-layer SRG identifiers assigned at the server layer, or summarizing the plurality of server-layer SRG identifiers assigned at the server layer.
