System and method for optimizing data forwarding performance of NFV

Abstract

The invention relates to a system and a method for optimizing data forwarding performance of NFV. The system comprises hardware accelerator equipment, wherein a Qos function module is arranged in thehardware accelerator equipment, and the NFV generates Qos parameters through the Qos function module, so that the Qos function of the NFV is achieved. Through adoption of the system and method for optimizing the data forwarding performance of the NFV, the hardware accelerator is added, and the Qos is sunk into the hardware accelerator, so that the influence of the Qos function on the performance of a DP layer is reduced. A CP layer issues Qos configuration parameters to the hardware accelerator equipment, and the hardware accelerator realizes the Qos function according to the configuration parameters. Due to the fact that the forwarding performance of the hardware accelerator is superior to the forwarding performance of a CPU, the data forwarding performance of the NFV is integrally improved, and meanwhile, due to the fact that the Qos function is not realized through the DP layer, the load of the DP layer is reduced.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to the QoS function field of NFV, and in particular to a system and method for optimizing NFV data forwarding performance. Background technique [0002] NFV (Network Function Virtualization) is a method that uses general-purpose hardware such as X86 and virtualization technology to carry software processing of many functions, thereby reducing the cost of expensive network equipment. NFV can decouple hardware and software and abstract functions. The functions of network equipment no longer depend on dedicated hardware, and resources can be fully and flexibly shared, enabling rapid development and deployment of new services, and automatic deployment, elastic scaling, fault isolation, and self-healing based on actual business needs. [0003] NFV is generally divided into forwarding plane and control plane (hereinafter referred to as DP and CP respectively). Genera...

AI Technical Summary

Problems solved by technology

[0005] In the existing technology, the NFV software forwarding architecture increases as the DP side functions increase and the packet processing process increases, resulting in more serious performance degradation

see figure 1 , 2 , the traditional NFV QoS function is implemented at the DP level. Adding the QoS function will increase the packet delay and reduce the packet transmission bandwidth, especially the impact of multi-level QoS on forwarding performance.
