A virtual network function and its method for realizing business processing

Abstract

The invention discloses a virtual network function and a method for realizing service processing thereof, comprising: the VNF divides the acquired VNF service resource capabilities into several unit granularity resources; the VNF creates and forwards routing information, and forwards the divided unit granularity resources The routing information is transmitted to the external router or interconnected device; when receiving the service data of the interconnected device, the VNF performs service processing according to the selected business processing logic. The present invention realizes the load balancing function of the VNF by sending the forwarding routing information determined according to the unit granular resource decision to the router or the docking device, and reduces the occupation of computing resources and increases the data transmission efficiency; due to the cancellation of the special load balancing function , to avoid traffic bottlenecks and delays in computing and data exchange, improve the efficiency of computing resources, ensure the performance of network data processing, enhance business experience, and support high-throughput services.

AI Technical Summary

Problems solved by technology

However, for businesses with a large amount of business data, this deployment scheme has many constraints and deficiencies

First, due to the use of virtual computing capabilities and virtual network cards, the network throughput of the load balancing function is limited

Secondly, the data forwarding between the load balancing function and the business processing function can only rely on Ethernet switches and / or virtual switches, and the data exchange capability becomes a bottleneck

In addition, the data is forwarded multiple times through the virtual switch, and the delay is relatively large, which not only affects the service experience, but also cannot meet and guarantee the basic needs of business functions for services with high delay requirements such as autonomous driving and Internet of Vehicles.
