Title:ResearchontheStabilityofCloudCommunicationSoftswitchSlicingDeploymentBasedonSDNandNFV
Introduction:
Cloudcommunicationserviceshavebecomeparamountintoday'sdigitalworld,leveragingthecapabilitiesofSoftware-DefinedNetworking(SDN)andNetworkFunctionVirtualization(NFV).Thesetechnologiesenablethevirtualizationandcentralizationofnetworkfunctions,leadingtomoreflexibility,scalability,andefficiency.Asthedemandfordiversecommunicationservicescontinuestogrow,itbecomesvitaltoexplorethestabilityofdeployingcloudcommunicationsoftswitchcapabilitiesthroughslicingusingSDNandNFV.
