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 s

Embodiment Construction

[0027] refer to figure 1 , shows a schematic diagram of a networking of an application scenario of the present invention, including: multiple clients, switches, network devices, and servers. The request messages sent by each client are unified through the switch to form a request stream and sent to the network device. The network device processes the protocol message in the above request stream and returns the processing result to the client, and sends the request data in the above request stream to The file is forwarded to the server for processing. Correspondingly, after the server processes the request data packets in the above request flow, it returns a return flow consisting of return packets, which is forwarded to the corresponding client through the network device.

[0028] When the traffic load forwarding method provided by the present invention is applied to the above-mentioned network device, the above-mentioned network device may be a frame-type tightly coupled dev...

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...
