A daughter card unit dynamic adaptation method and line card board

Abstract

The invention discloses a method for dynamic adaptation of a sub-card unit and a line card board, which are applied to the dynamic adaptation of a routing device and a sub-card unit. The host unit is provided with a line card board, and the line card board includes a first static area and a line card board. In the reconfiguration area, the data in the first static area remains unchanged after loading, and the data in the reconfiguration area dynamically changes according to the type of the sub-card unit corresponding to the reconfiguration area, the method includes: loading The first static area; identifying the type of the currently inserted daughter card unit, respectively loading the reconfiguration area corresponding to the daughter card unit according to the type of the daughter card unit; through the first static area and the The reconfiguration area corresponding to the daughter card unit communicates with the daughter card unit. By adopting the present invention, the dynamic adaptation of the host unit and different types of sub-card units can be realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a dynamic adaptation method for a daughter card unit and a line card board. Background technique [0002] Routing equipment is a network equipment that works on the third layer of the open system interconnection protocol model, that is, a packet switching equipment at the network layer. It has the ability to connect different types of networks and can select data transmission paths. Routing devices usually connect two or more IP (Internet Protocol, Internet Protocol) subnets or logical ports identified by point-to-point protocols, and have multiple physical interfaces. The physical interface of the routing device is rich in types, which can provide various Ethernet network interfaces with different interface rates and different service characteristics, SDH / SONET (Synchronous Digital Hierarchy / Synchronous Optical Network, Synchronous Digital Hierarchy / Synchronous Optical Ne...

Problems solved by technology

[0006] In the prior art, in order to meet the adaptation of various types of sub-card units, the host unit of the routing device is fixedly configured with a bus with specific protocols and physical interfaces, and each sub-card unit is connected to the host unit of the routing device. The bus is processed into the same type of bus to achieve communication with the host unit of the routing device. It can be seen that in the prior art, the host unit of the routing device cannot dynamically adapt to the sub-card units of different bus types
