Abstract

The invention discloses a method for accelerating the first distribution of data packets by using the FDir function of the network card on the NFV platform, and using the FDir function to cache the mapping relationship between the quintuple of the active flow and the hardware receiving queue bound to the target VNF ​​into PMFT table, and then the network card can directly send the data packet to the target VNF ​​without CPU intervention; due to the capacity limitation of the PMFT table, for inactive flows, it is not cached to the PMFT table, Instead, the CPU is used in combination with the network policy to calculate the target VNF ​​and then complete the distribution; the activity of each network flow can also be counted through a user-defined algorithm, and the PMFT table is periodically updated to maximize the acceleration benefit. The present invention can save the CPU resources of the host computer without introducing special hardware, and further enhance the overall performance of the NFV platform framework.

Description

technical field [0001] The invention relates to the NFV platform, in particular to the first distribution technology of data packets. Background technique [0002] Network function virtualization (NFV) is a technology that builds virtual machines based on cheap general-purpose servers, and replaces traditional hardware NF such as switches, routers, and firewalls through software programs that perform corresponding functions. The emergence and development of NFV have greatly alleviated the shortcomings of traditional hardware solutions in cloud environments, such as long integration cycles, high deployment costs, and lack of unified management mechanisms. However, there is a natural gap between general-purpose hardware and special-purpose hardware in specific tasks. How to make the performance of NFV platform comparable to that of physical hardware clusters is a constant challenge on the road to commercialization. To this end, researchers have proposed a variety of NFV frame...
