Hardware acceleration method and related device

A communications system, comprising a virtualized network function manager (VNFM) and a virtualized infrastructure manager (VIM);

• wherein
• the VNFM is configured to:
• send a second request message to a VIM, wherein the second request message is configured to cause the VIM to deploy a to-be-accelerated virtualized network function (VNF) onto a host in a management domain of the VIM, wherein a hardware resource of the host meets a requirement of the to-be-accelerated VNF, and the requirement of the to-be-accelerated VNF includes information indicating a type of a required hardware acceleration resource and a size of the required hardware acceleration resource in the to-be-accelerated VNF;
• the VIM is configured to:
• receive the second request message from the VNFM;
• and deploy the to-be-accelerated VNF onto the host in the management domain of the target VIM.

A hardware acceleration method, comprising:

• sending, by a network functions virtualization orchestrator (NFVO), first request information to a virtualized infrastructure manager (VIM), wherein the first request information is configured to request the VIM to deploy the to-be-accelerated VNF onto a host in a management domain of the VIM, wherein a hardware resource of the host meets a requirement of the to-be-accelerated VNF, and the requirement of the to-be-accelerated VNF includes information indicating a type of a required hardware acceleration resource and a size of the required hardware acceleration resource in the to-be-accelerated VNF;
• and
• receiving, by the VIM, the first request information from the NFVO;
• and
• deploying, by the VIM, the to-be-accelerated VNF onto the host in the management domain of the VIM.
