A congestion control method and network element equipment

Abstract

Embodiments of the present invention provide a congestion control method and network element equipment, which relate to the communication field. The method includes: receiving a capacity expansion request message, where the capacity expansion request message carries a resource used to indicate the resource size required by a congested base station Parameters; send the expansion request message to the network function virtualization orchestrator NFVO, the expansion request message is used to request the NFVO to determine the virtualization infrastructure manager VIM that can provide the resources required by the base station; receive the NFVO A resource reservation success message sent, the resource reservation success message carrying the identification information of the VIM; according to the resource parameters and the identification information of the VIM, requesting the VIM to allocate resources required by the base station and The allocated resources are configured on the base station to implement congestion control on the base station. The invention can improve the quality of service transmission or ensure that users normally request services.

Description

technical field [0001] The invention relates to the communication field, in particular to a congestion control method and network element equipment. Background technique [0002] NFV (Network Function Virtulization, Network Function Virtualization) network is a network that can decouple hardware and software, so that the functions of network devices no longer depend on dedicated hardware resources, and network resources can be shared flexibly. It is precisely because of this flexible sharing of network resources that a large number of new services can be quickly developed or deployed on the NFV network. As more services are deployed, more users access the NFV network. A large number of users accessing the NFV network often leads to congestion on the data plane of the NFV network. [0003] At present, when congestion occurs in the NFV network, it is necessary to control the congestion to eliminate the congestion. The implementation process can be as follows: eNB (evolved Nod...

Problems solved by technology

[0005] When PCRF controls congestion, the strategies adopted are to prevent new users from accessing or reduce the code rate of services. Reducing the service code rate will reduce the quality of service transmission, and preventing new users from accessing the NFV network will cause users to be unable to request services.
