[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

The invention discloses a daughter card unit dynamic adaptation method and a line-card board, and is applied to dynamic adaption between a routing device and daughter cards. The line-card board is arranged in a host machine unit. The line-card board comprises a first static domain and a reconfiguration domain. Data in the first static domain are kept unchanged after being loaded. Data in the reconfiguration domain are dynamically changed according to the types of the daughter cards corresponding to the reconfiguration domain. The daughter card unit dynamic adaptation method comprises the following steps: the first static domain is loaded; the types of the daughter cards inserted at present are identified, and the reconfiguration domain corresponding to the daughter cards is loaded respectively according to the types of the daughter cards; the routing device is in communication with the daughter cards through the first static domain and the reconfiguration domain corresponding to the daughter cards. The daughter card unit dynamic adaptation method and the line-card board are adopted to realize the dynamic adaption between the host machine unit and different types of daughter cards.
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. There are many types of physical interfaces of routing equipment, 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...
