Abstract

The present application provides a method, apparatus and server for replacing a hardware accelerator, wherein, the method comprises: receiving a hardware accelerator replacement request, wherein, thehardware accelerator replacement request is used for instructing to replace a first hardware accelerator used by a target virtual machine on a front-end server with a second hardware accelerator; sending a notification message for replacing the first hardware accelerator to the front-end server; Converting the pre-acquired virtual network service VNF configuration information corresponding to thetarget virtual machine into configuration information corresponding to the second hardware accelerator when a notification message indicating that the first hardware accelerator can be replaced is received; configuring the second hardware accelerator based on the configuration information corresponding to the second hardware accelerator. The application can realize the dynamic replacement of the hardware accelerator, which enables the hardware accelerator to be shared among a plurality of VNF virtual machines, that is, the utilization rate of the hardware accelerator is greatly improved, and accordingly, the hardware cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of network function virtualization, in particular to a hardware accelerator replacement method, device and server. Background technique [0002] Network Functions Virtualization (NFV) uses virtualization technology to divide the functions of the network node layer into several functional blocks, which are implemented in software, and are no longer limited to the hardware architecture. At the heart of Network Functions Virtualization (NFV) is the Virtual Network Feature (VNF), which provides network functions that can only be found in hardware. [0003] Hardware accelerator is an important hardware resource in NFV, which can significantly improve the performance of VNF services. However, the hardware accelerator costs are relatively high, and if the hardware accelerator can be shared among multiple VNF virtual machines, the hardware cost will be greatly reduced. [0004] If hardware accelerators are shared ...
