Problems solved by technology

[0006] In the process of realizing the present invention, the inventor finds that the prior art has at least the following disadvantages: since the SC module and the SMi sub-module are usually arranged on two different boards, software between different boards is required to communicate to configure the SMi Sub-modules increase system complexity and slow response

Embodiment 1

[0048] Such as figure 2 Shown is a flow chart of Embodiment 1 of the port fault handling method of the present invention, including:

[0049] Step 101, when the SMe sub-module detects that a downlink sub-port between the SC module and the SMe sub-module fails, the SMe sub-module sends information that the downlink sub-port fails to the SMe sub-module The SMi submodule in the SM module where it is located.

[0050] Step 102, the SMi sub-module sends a cell to the SC module, and the cell carries information that the downlink sub-port fails.

[0051] Step 104, the SC module sends a request from the SMi sub-module to transmit cells through the downlink sub-port that has failed, and the SC module refuses to reply to the authorization; Other downlink sub-ports other than the port request to transmit cells, and reply authorization.

[0052] In this embodiment, for the request sent by the SMi sub-module to transmit cells through the downlink sub-port that has failed, the SC module...

Embodiment 2

[0058] Such as image 3 Shown is the flow chart of Embodiment 2 of the port fault handling method of the present invention, including:

[0059] Step 201, when the SC module detects that an uplink sub-port between itself and each SMi sub-module fails, when the SC module receives a request from the uplink sub-port, it refuses to reply to the authorization, and sends a cell to the sending request For the SMe submodule in the SM module where the SMi submodule is located, the cell carries the failure information of the uplink subport.

[0060] Step 202, the SMe sub-module sends the failure information of the uplink sub-port to the SMi sub-module.

[0061] Step 204, the SMi sub-module selects another uplink sub-port to send a request to the SC module.

[0062] Step 206: After receiving the request sent by the SMi sub-module through the other uplink sub-port, the SC module sends the authorization to the SMi sub-module through the SMe sub-module in the SM module where the SMi sub-mo...

Embodiment 3

[0067] Such as Figure 4 Shown is the flow chart of Embodiment 3 of the port failure processing method of the present invention, including:

[0068] Step 301, when the SC module detects that the first uplink sub-port fails, the SC module sends a cell to the first SMe sub-module through at least two downlink sub-ports connected to the SC module, and the cell carries the occurrence of the first uplink sub-port Fault information, in this embodiment, the at least two downlink sub-ports include the first downlink sub-port and other downlink sub-ports, the SC module does not know whether the first downlink sub-port fails, therefore, the SC module passes the first downlink sub-port A downlink subport and other downlink subports except the first downlink subport send cells to the first SMe submodule, so as to prevent that when the first downlink subport also fails, the first SMe submodule can Cells are received through other downlink subports except the first downlink subport.

Abstract

The invention discloses a port fault treatment method and system, wherein the method includes that when a first up sub-port between a SMi sub-module and the SC module is in trouble, the SC module transmits a information of the first up sub-port fault to the SMi sub-module through a SMe sub-module to make the SMi sub-module transmit request through other up sub-module except the first up sub-port;the SC module replies authorization to the request received through other up sub-ports except the first up sub-port. By using the technical solution provided by the present invention, when port is introuble, other ports are used for transmitting request, SMi sub-module is not needed to configure, thereby reducing system complexity and increasing response speed.

Description

technical field [0001] The invention relates to switching network technology, in particular to a port fault processing method and system. Background technique [0002] A switch matrix (Crossbar) structure is a switching network structure, usually including multiple uplink switching memory ingress (SMi for short) submodules, multiple downlink switching memory egress (SMe for short) submodules and Switching Crossbar (SC for short) module, the SMi and SMe sub-modules are used to complete the switching buffer and scheduling of cells, the SC module is used to complete the arbitration of cell requests, and the SMi sub-module and SMe sub-module are connected to the SC module Connect via port. The SMi sub-module and the SMe sub-module together form a switching memory (Switching Memory, SM for short) module. [0003] The cell interaction between the SMi sub-module and the SMe sub-module is realized through a request-authorization method. For example, both SMi sub-modules send a req...
