Multi-processing unit route system

Abstract

The present invention proposes a multi-processing unit routing system, including multiple processing units, a virtual routing kernel and a resource allocation / reservation control management module; the virtual routing kernel is connected to each processing unit through a data channel; the processing unit includes a service module and forwarding module; the resource allocation / reservation control management module is connected to each processing unit, responsible for the allocation, recycling, reservation and other control and management of resources required by different data forwarding classes, and establishes the corresponding export mapping relationship, And distribute the corresponding relationship between the forwarding class and the export to each processing unit; the present invention makes full use of the processing performance of each processing unit to avoid data exchange bottlenecks; ensure the reliable transmission of data between each processing unit inside the device; due to the The interface of the routing system of the multi-processing unit adopts a global description, so that the system can perform one-time routing for data forwarding and forward it immediately, and there is no need to centrally forward data by a certain processing unit.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a system for realizing high-efficiency routing and forwarding of datagrams on devices with multiple processing units in the current Internet. Background technique [0002] With the continuous development of information technology, the Internet has gradually penetrated into all aspects of people's lives, and the amount of data transmitted on the Internet has exploded. have put forward higher and higher demands. From the perspective of current network equipment, there are three ways to implement datagram routing and forwarding as follows: [0003] Mode 1: The device has only one CPU processing unit, which is used to implement routing and forwarding among multiple ports on the processing unit. The advantage of this method is that the structure is simple, but the disadvantage is that the number of ports, packet forwarding rate and throughput are limited. ...

AI Technical Summary

Problems solved by technology

[0006] Due to their respective defects, these three methods do not support data forwarding with QoS requirements in the routing table; the data forwarding channel between the processing units in methods 2 and 3 does not have QoS characteristics, which may cause data loss inside the device; the three methods None of the methods can meet the high-speed and large-capacity data exchange, and cannot guarantee the reliable transmission of data

From the perspective of existing technologies, there is no way to improve the forwarding speed and increase the forwarding efficiency by improving the datagram routing process or processing method, improving the forwarding table, improving the internal data forwarding channel, etc., so as to ensure the QoS of data transmission Features, a technical solution to optimize the overall forwarding performance of the device
