Distributed network apparatus

Abstract

The invention provides a distributed network apparatus. The distributed network apparatus includes a main control board card, service board cards and an inter-board channel; the CPU of the main control board card is used for generating network forwarding table entries for the service board cards, and issuing the network forwarding table entries to the service board cards, and issuing corresponding flow-splitting strategy table entries to flow-splitting hardware and CPUs of the service board cards according to flow control strategies issued by a management side; and the flow-splitting hardware of the service board cards is used for storing the flow-splitting strategy table entries in flow-splitting strategy tables of the flow-splitting hardware, and transmitting messages which enter from network ports to the CPUs of corresponding service board cards according to the flow-splitting strategy tables of the flow-splitting hardware; and the CPUs of the service board cards are used for storing the flow-splitting strategy table entries in flow-splitting strategy tables of the CPUs, and performing application processing and network forwarding processing on the messages according to the flow-splitting strategy tables of the CPUs. With the distributed network apparatus of the invention adopted, problems brought about by requirements for configuring static routing or strategy routing for flow guiding can be solved, management is simpler, and management IP addresses can be saved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a distributed network device. Background technique [0002] With the expansion of network scale and the increase of network traffic, networking becomes increasingly complex. For the management and operation of the network, it is necessary to provide high-speed network and ensure the security of the network. The traditional network architecture is gradually challenged by practical applications. [0003] In a large network, the backbone link must guarantee the network forwarding, network application processing and network security processing of the message at the same time, each of which requires special equipment or functional modules to realize. The so-called network forwarding coverage usually refers to the packet forwarding of data link layer and network layer packets composed of routing entries, access control rules, packet filtering rules, ARP entries, etc. in the net...

Problems solved by technology

In addition to the complex configuration, this technical solution also has the following disadvantages: each service board operates independently, and they are simply connected together in series. Logically, there is no difference in the networking mode of the first solution. Many problems of the first solution are the same. inherit

In addition, since the physical form is already different from Solution 1, in Solution 3, each board needs to be configured with static routing or policy routing for traffic diversion, which requires administrators to manually operate, and it is difficult to maintain when there are a large number of boards
