Distribution method of network traffic, main control board, interface board and gateway device

Abstract

The invention provides a network traffic shunting method, a main control board, an interface board and a gateway device. The method includes the following steps that: interface division settings of a user for the interfaces of a gateway device are received, and interface configuration information is generated; and the interface configuration information is sent to the interface board, so that the interface board can set internal network-domain interfaces according to the interface configuration information and can carry out intra-domain forwarding on network traffic of network-domain interfaces simultaneously comprises an incoming interface and an outgoing interface. With the network traffic shunting method provided by the invention adopted, network traffic exchanged between internal network interfaces are directly forwarded to other network elements in the internal network domain at the interface board, and the network traffic is not required to be forwarded to other business boards, so that software loaded by CPUs on the other business boards does not need to search routing table entries to realize the forwarding of the network traffic, and therefore, the load of the CPUs of the other business boards can be decreased, the traffic forwarding speed of the business boards can be improved, and the performance of the whole gateway can be improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network flow distribution method, a main control board, an interface board and a gateway device. Background technique [0002] At present, network applications and network requirements are becoming more and more complex. Users are constantly adding business traffic to realize network intelligence, and are no longer limited to "internal network access to external network", and gradually require each region to realize two-way interworking or single communication. [0003] For the intranet, that is, the networking situation of interactive traffic between network elements in different regions in the intranet domain, the main implementation methods of the prior art are as follows: the gateways of the intranet domain network elements such as terminals and servers all point to the core gateway, and All interactive traffic is routed and forwarded by the software loaded on...

AI Technical Summary

Problems solved by technology

However, the existing technology uses the software loaded on the core gateway CPU to forward traffic, which consumes CPU resources of the device, and it is necessary to configure forwarding for all traffic including intranet access to the intranet, intranet access to the extranet, and extranet access to the intranet. Policies, due to the mixed configuration policies, the configuration of the core gateway is complicated, the forwarding pressure is high, and cumbersome, etc.
