Problems solved by technology

[0003] However, when users use the switching network, they usually gradually expand the capacity. In the initial configuration, only a few LPUs need to be configured, and it may take several years to expand the capacity to increase the number of LPUs. Then, if the SFU is fully configured in the initial configuration , SFU is a very expensive device, which makes the cost of initial configuration higher

Abstract

The present invention provides a line processing unit and a switch fabric system. The line processing unit includes an FIC and an FE, where the FIC is connected to the FE through a first connection line. In embodiments of the present invention, an LPU and a switching capability can be configured in demand, thereby reducing initial configuration costs.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a line processing board and a switching network system. Background technique [0002] The packet can be switched and processed through a switching network access controller (Fabric Interface Controller, FIC) and a switching fabric element (Fabric Element, FE). The FIC is generally located on a line processing unit (Line Processing Unit, LPU), and the FE is generally located on a switching fabric unit (Switch Fabric Unit, SFU) independent of the LPU. In the prior art, in a large-capacity switching system, each FIC on the LPU is respectively connected to each FE on all SFUs. According to the connection relationship above, in order to switch packets from one port of the LPU to any other port, no matter how many LPUs there are, the SFU must be fully configured. For example, if the number of fully configured SFUs is 3, no matter whether there are 1, 2 or more LPUs, 3 S...
