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

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The invention proposes a brand-new distributed network device to solve the bottleneck faced by the prior art. Please refer to Figure 5 , in the distributed network device of the present invention, it includes a main control board, one or more types of service boards and switching boards; each board is connected through an internal switching network (Fabric). The switch board is not a necessary component, and the switch board can be introduced when the network device has more network access requirements. Both the main control board and the service board generally include a CPU, a memory and a non-volatile memory. In the present invention, the service board also includes a network interface (hereinafter referred to as "network port") and distribution hardware connected to the network port. The main function of the distribution hardware is to distribute the m...

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...
