Problems solved by technology

If the entire data packet is directly and roughly synchronized between VNFs, this problem can be solved, but it is limited by PCI-E transmission, which will affect the overall performance of the system. Therefore, a heterogeneous VNF service chain data synchronization mechanism is required.

Embodiment

[0041] Such as figure 1 As shown, this embodiment provides a network function virtualization system based on GPU accelerated optimization, the system includes:

[0042] GPU shared buffer: opened in GPU memory;

[0043] Network function service chain: multiple virtual network function modules form a network function service chain, and each virtual network function module operates in one of the following three ways: method 1, use CPU to run, method 2, use GPU to run, method 3. Use the GPU and run with the GPU shared buffer;

[0044] The system designs a multi-pipeline GPU scheduling mode;

[0045] When the network function service chain includes at least two virtual network function modules with different operating modes, the network function service chain is called a heterogeneous network function service chain. Package synchronization.

[0046] The system of the present invention solves the duplicate PCI-E data copy caused when multiple VNFs occupy the GPU alone by providi...

Abstract

The invention relates to a network function virtualization system based on accelerated optimization of a graphics processing unit. The system comprises a GPU shared buffer area which is developed in a GPU video memory; the network function service chain is formed by a plurality of virtual network function modules, and the operation mode of each virtual network function module adopts one of the following three modes: a first mode of operating by using a CPU, a second mode of operating by using a GPU, and a third mode of operating by using the GPU and cooperating with a GPU shared buffer area; according to the system, a multi-pipeline GPU scheduling mode is designed; and when the network function service chain is a heterogeneous network function service chain, the heterogeneous network function service chain performs data packet synchronization based on a heterogeneous service chain synchronization mechanism during operation. Compared with the prior art, the method has the advantages that the data volume copied by the memory among the VNFs is reduced, hardware resources are utilized to the greatest extent, and data synchronization among the heterogeneous VNFs is realized.

Description

technical field [0001] The invention relates to the technical field of network function virtualization, in particular to a network function virtualization system based on graphic processor acceleration optimization. Background technique [0002] Network Function Virtualization (Network Function Virtualization, NFV) technology can virtualize network functions that can only operate on specific hardware on a general-purpose platform, so that software-defined network functions can replace traditional hardware network functions, thus making the network The implementation, deployment and management of functions are more convenient. In the NFV system, a service chain is formed by customizing various virtualized network functions (VNFs), so as to provide customized network services. The input of each VNF on the service chain is the output of the previous VNF, and a service chain can be regarded as a one-way linked list logically. With the improvement of network bandwidth, improvin...
