Problems solved by technology

[0007] The defect of the prior art is that: as the performance of mid-to-high-end network equipment is getting higher and higher, the management information capacity is also increasing. However, due to the limitation of the management channel capacity of the FE interface, the management between the interface card and the main control card Packet interaction becomes more tense
[0008] Further, in the prior art, the main control card is connected to the FE interface of each interface card through the HUB chip. Since the HUB is a bus sharing method, that is, the communication resources of the bus are occupied by a group of link information at a certain moment, due to the bus sharing method Occupancy is limited, thus, reducing the efficiency of transferring effective management data

Embodiment Construction

[0023] The present invention provides a management information interaction system in network equipment. The main purpose of the system is to provide a higher-speed physical channel on the basis of the existing system structure, and further provide a larger management channel between the main control card and the interface card. channel capacity.

[0024] Restricted by the architecture of mid-to-high-end network equipment, in this field, the basic requirements to be met by the implementation of the management channel are:

[0025] 1) The management data packets between the main control card and each interface card are transmitted in the management channel, so the capacity of the management channel (the amount of data transmitted per second) directly affects the interaction ability of management data between the main control card and each interface card, Therefore, a large-capacity management channel should be provided between the main control card and the interface card;

Abstract

An interactive system of managed data in network device comprises main control card and interface card. It is featured as setting CUP and physical layer interface chip on two said cards, connecting two said cards to rear panel through Ethernet GE interface of 1000 mega for achieving data interacting between main control card and physical interface chip on interface card physical layer by utilizing rear panel wiring, setting GE interface as optical interface mode for realizing interconnection of main control card to interface card by using SerDes signal wire on rear panel.

Description

technical field [0001] The invention relates to the communication field, in particular to a data interaction system in a high-end router or an Ethernet switch in the network communication field, and an interface card and a main control card dedicated to the data interaction system. Background technique [0002] Most of the existing mid-to-high-end routers and Ethernet switches (hereinafter collectively referred to as mid-to-high-end network devices) are composed of a main control card, an interface card, a backplane and a power supply. The main control card is responsible for initialization, dynamic configuration, and routing management of the interface card; the interface card is responsible for forwarding data packets of different services (such as ATM, POS); Cards and interface cards are connected to the backplane and interconnected through the backplane to realize data interaction. [0003] According to logical division, the connection between the main control card and ...
