Traffic load forwarding method, main control board, service board and network equipment

Abstract

The invention provides a traffic load forwarding method, a main control board, service boards and network equipment. The traffic load forwarding method comprises the steps of: configuring an address information list including corresponding relationships between different service boards and network segments IP; issuing the address information list to an interface of a cloud board, so that the interface of the cloud board configures an access control list ACL according to the address information list; receiving protocol messages which are used for requesting IP addresses and forwarded by the service boards; allocating the IP addresses to a client which sends the protocol messages according to the address information list, so that the interface of the cloud board matches data messages containing the IP addresses according to the access control list ACL, and forwards the successfully-matched data message to the corresponding service boards. With the adoption of the traffic load forwarding method provided by the invention, the burden of the service boards and the main control board can be effectively alleviated, the CPU loss can be reduced, and the service processing performance of a single service board can be improved, thereby improving the processing performance of the cloud board.

Description

technical field [0001] The invention relates to the technical field of network applications, in particular to a flow load forwarding method, a main control board, a service board and network equipment. Background technique [0002] With the convergence of networks and the rapid growth of high-speed network access requirements, cloud board technology emerged as the times require. The cloud board technology abstracts multiple service boards into one logic board to realize load sharing and forwarding of traffic. [0003] In the implementation of cloud board technology, how to achieve efficient traffic load sharing is the key. The existing cloud board technology implements traffic load sharing through the quintuple separation algorithm of the bond port. The so-called bond refers to binding multiple physical network cards into one logical network card. However, in the prior art, when the quintuple separation algorithm of the bond interface is used to realize traffic load sharin...

Problems solved by technology

However, in the prior art, when the quintuple separation algorithm of the bond interface is used to realize traffic load sharing, because the quintuples of the protocol packets and data packets of the same flow are different, and the request data packets and the quintuple of the same flow are different. The five-tuple of the return data message is just the opposite, and the distribution results calculated from this must be different, so there is often a problem that the protocol message and data message sent by the same client cannot be sent to the same service board for processing

If the data packet and protocol packet sent by the same client are sent to different service boards through the bond port, the data packet needs to be forwarded to the service board that processes the corresponding protocol packet through the main control board, resulting in data packet The processing delay increases the burden on the service board and the main control board, and reduces the forwarding performance of data packets
