Embodiment Construction

[0035] In order to facilitate a further understanding of the method and achieved effects of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] The hardware architecture of middle and high-end routers and switches based on distributed architecture such as figure 1 As shown, the whole system includes a main control module, a switching network module, an interface processing unit, and a service processing unit. The main control module of the system adopts 1+1 redundant backup. The main control module focuses on the internal transmission of business control protocols (such as routing protocols), and provides control information transmission through independent channels; the switching network adopts a multi-level switching matrix structure to realize distributed switching. ; The interface unit realizes high-speed message processing; there are many types of business processing units, such as IPv4 / IPv...

Abstract

The invention discloses a distributed many-to-many equipment communication and management method. The method comprises the following steps of (1) starting two background tasks after each printed-circuit board of a rack type router or exchange equipment are started; (2) causing each printed-circuit board to recording the state of other printed-circuit boards; (3) packaging data needing to be transmitted by an application layer through a private protocol, setting a corresponding destination MAC (Multi-Access Computer) address and a corresponding source MAC address according to a destination printed-circuit board and a sent printed-circuit board, and sending to the destination printed-circuit board in a reliable transmission mode; (4) through a timer mechanism, realizing the retransmission of a data message and the status checkout of the printed-circuit board; (5) sending packets; and (6) receiving the packets. The method adopts a transmission mechanism based on two layers of Ethernets to realize the reliable transmission and management among multiple master cards, various line interface cards and various business processing cards in the rack type router through reliable multipoint-to-multipoint transmission among the printed-circuit boards of the rack type equipment, so that the high reliability of core equipment in a network layer is ensured.

Description

technical field [0001] The present invention relates to a distributed multi-to-many device communication and management method, in particular to a communication mechanism and communication mechanism between a main control card, various line interface cards, and various service processing boards in a rack-type multi-service router. mutual management methods. Background technique [0002] In mid-to-high-end routers or switches, the main communication mechanism between various types of cards is as follows: the main control card must be able to sense other cards in time, and send relevant user configuration information to other interface cards or service cards, so as to realize the router Or enable the switch function. Various interface line cards must be able to sense the status of multiple business processing cards and switching cards and related load information in a timely manner, so as to perform appropriate scheduling and realize load balancing and business processing. ...
