Abstract

The present invention provides a hardware acceleration method and a communications system. The hardware acceleration method includes: 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; 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.

2 . The communications system according to claim 1 , wherein a size of the hardware resource of the host is greater than the size of the required hardware acceleration resource in the to-be-accelerated VNF, and a type of the hardware resource is consistent with the type of the required hardware acceleration resource in the to-be-accelerated VNF.

3 . The communications system according to claim 1 , wherein the VIM is further configured to:
send hardware acceleration information to the NFVO, wherein the hardware acceleration information comprises information indicating a size of a hardware resource reported by the VIM, wherein the size the of the hardware resource is a size of a hardware resource of a host having a largest hardware resource in the management domain of the VIM; and the NFVO is further configured to: receive the hardware acceleration information.

4 . The communications system according to claim 3 , wherein the size of the hardware resource reported by the VIM is the largest among hardware resource sizes reported by each VIM in the management domain of the NFVO.

5 . 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.

6 .
