Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Be illustrated in figure 1 as the three grades of switching network structural representations of Crossbar that relate in the embodiment of the invention, the first order comprises a SMi submodule 11 and the 2nd SMi submodule 21, the second level is SC module 3, the third level comprises a SMe submodule 12 and the 2nd SMe submodule 22, the one a SMi submodule 11 and a SMe submodule 12 form one the one SM module 7, the two SMi submodules 21 and the 2nd SMe submodule 22 is formed one the 2nd SM module 8.Usually the SM module is a chip, SMi submodule and SMe submodule are two submodules in the SM chip, connect by port between SMi submodule and the SMe submodule, specific to Fig. 1, connect by port 4 between the one a SMi submodule 11 and the SMe submodule 12, connect by port 5 between the 2nd SMi submodule 21 and the 2nd SMe submodule 22.
Connect by first up subport 111, the second up subport 112 between the one SMi submodule 11 and the SC module 3, be connected with the 4th up subport 212 by the 3rd up subport 211 between the 2nd SMi submodule 21 and the SC module 3, connect by first descending subport 121, the second descending subport 122 between a SC module 3 and the SMe submodule 12, connect by the 3rd descending subport the 221, the 4th descending subport 222 between SC module 3 and the 2nd SMe submodule 22.Because cell is to send to SC module 3 from each SMi submodule, be called up subport so connect each port of SMi submodule and SC module 3, cell is to send to the SMe submodule from SC module 3, is called descending subport so connect each port of SC module 3 and each SMe submodule.Because SMi submodule and SMe submodule are formed a SM module, connectivity port between SM module and the SC module comprises descending subport and up subport, descending subport and up subport are formed a port, for example, the first up subport 111 and the first descending subport 121 are formed first port, the second up subport 112 and the second descending subport 122 are formed second port, the 3rd up subport 211 and the 3rd descending subport 221 are formed the 3rd port, the 4th up subport 221 and the 4th descending subport 222 are formed the 4th port, and each descending subport is corresponding to a up subport.First port or the second port transmission cell can be passed through between SM module 7 that the one a SMi submodule 11 and a SMe submodule 12 are formed and the SC module 3, the 3rd port or the 4th port transmission cell can be passed through between the 2nd SM module 8 that the 2nd SMi submodule 21 and the 2nd SMe submodule 22 are formed and the SC module 3.
The Crossbar switch network architecture can also have other multistage exchanged form usually; be that example describes only in the embodiment of the invention with as shown in Figure 1 mechanism; in addition for the ease of statement; two SM modules have only been provided among Fig. 1; port between SM module and the SC module also provides two, can have a plurality of in actual applications.
Among Fig. 1, the port between SC module and each the SM module has a plurality of, the situation difference that port breaks down, and the situation of then handling port failure is also different.
One, breaks down when descending subport
For switching network structure as shown in Figure 1, for the fault of SC module to the descending subport of each SMe submodule, itself can't detect port failure the SC module, need be detected by each SMe submodule.
Be illustrated in figure 2 as port fault processing method embodiment one flow chart of the present invention, comprise:
The requirement that step 104, this SC module send over for the SMi submodule is by the request of the descending subport transmit cell that breaks down, and SC module refusal is replied and authorized; The requirement that sends over for the SMi submodule is replied mandate by the request of other the descending subport transmit cells except that the described first descending subport.
In the present embodiment, the requirement that this SC module sends over for the SMi submodule is by the request of the descending subport transmit cell that breaks down, SC module refusal is replied and is authorized, so just can mask the descending subport that breaks down, do not re-use the descending subport transmit cell that breaks down, can avoid cell to be dropped.
For embodiment one better is described, with structure shown in Figure 1 is example, when a SMe submodule 12 detects the first descending subport 121 and breaks down, the information that the first descending subport 121 that sends the one SMe submodule 12 breaks down is to a SMi submodule 11, the one SMi submodule 11 sends cell to SC module 3, carry the information that the first descending subport breaks down in the overhead byte of described cell, SC module 3 can know that fault has taken place the first descending subport 121.In the present embodiment, a SMi submodule 11 can pass through the first up subport 111, also can send cell to SC module 3 by the first up subport 121.
After the request of first descending subport 121 transmit cells was passed through in the requirement that receives a SMi submodule 11 transmissions, SC module 3 refusals sent and license to a SMe submodule 12.Because a SMi submodule 11 receives a SMe submodule 12 and sends the information that the first descending subport 121 breaks down, therefore, the one SMi submodule sends and requires to pass through the request of other the descending subport transmit cells that are connected with SC module 3 except that the first descending subport 121 to SC module 3, for example require to send cell by the second descending subport 122, SC module 3 sends then and licenses to a SMe submodule 12, the one SMe submodule 12 sends to a SMi submodule 11 with mandate, the one SMi submodule 11 sends cell to SC module 3, and SC module 3 sends to a SMe submodule 12 with the cell that receives by the second descending subport 122.
Need to prove, answer mandate involved in the embodiment of the invention refers to, the SMi submodule sends request to the SC module, if the SC module allows described SMi submodule to send cell to purpose SMe submodule, then the SC module sends the SMe submodule that the SMi submodule that licenses to and send request belongs to same SM module, and the SMe submodule that receives mandate then sends the SMi submodule that licenses to and send request.
Two, break down when up subport
For switching network structure as shown in Figure 1, for the fault of each SMi submodule to the up subport of SC module, SC module 3 itself can detect port failure.Whether promptly detect up subport breaks down.
Be illustrated in figure 3 as port fault processing method embodiment two flow charts of the present invention, comprise:
With structure shown in Figure 1 is example, and after SC module 3 detected the 3rd up subport 211 and breaks down, for the request that the 2nd SMi submodule 21 sends by the 3rd up subport 211, SC module 3 refusals were replied and authorized.Simultaneously SC module 3 is after detecting the 3rd up subport 211 and breaking down, send cell to the 2nd SMe submodule 22, carry the information that the 3rd up subport 211 breaks down in the cell, in the present embodiment, SC module 3 can be passed through the 3rd descending subport 221, also can pass through the 4th descending subport 222, send cell to the two SMe submodules 22.The 2nd SMe submodule 22 sends to the 2nd SMi submodule 21 with the information that the 3rd up subport 211 breaks down, the 2nd SMi submodule 21 shieldings the 3rd up subport 211, select to send request to SC module 3, for example can send request to SC module 3 by the 4th up subport 212 by other the up subports that are connected with the 2nd SMi submodule 21 except that the 3rd up subport 211.
Three, all break down when up subport and descending subport
For switching network structure as shown in Figure 1, when the up subport of a port and descending subport all break down, because the SC module is different with negotiation mode between the SM module, the method difference of troubleshooting then.Consult to be meant herein, pass through the process of cell transfer port status information between SMi submodule, SMe submodule and the SC module.Negotiation mode between SC module and the SM module can have following two kinds: the state information that the cell that (1) each port sends can only carry described port self; (2) cell that sends of each port state information that all can carry all of the port.
Be illustrated in figure 4 as port fault processing method embodiment three flow charts of the present invention, comprise:
Step 301, when the SC module detects the first up subport and breaks down, the SC module sends cell to a SMe submodule by at least two descending subports that are connected with the SC module, carry the information that the first up subport breaks down in the cell, in the present embodiment, these at least two descending subports comprise the first descending subport and other descending subport, the SC module does not know whether the first descending subport breaks down, therefore, the SC module sends a SMe submodule by the first descending subport and other the descending subport except that the first descending subport with cell, to prevent that when the first descending subport also breaks down a SMe submodule can be received cell by other the descending subport except that the first descending subport.
Step 302, when a SMe submodule detects the first descending subport and breaks down, the information that the first descending subport is broken down sends to a SMi submodule, and the information that the first up subport breaks down is sent to a SMi submodule.
Step 303, a SMi submodule send cell to the SC module by other the up subports except that the first up subport, carry the information that the first descending subport breaks down in the cell, make the SC module for the request that sends by the first up subport, SC module refusal is replied and is authorized, and for the request that requires to send by the first descending subport cell, the SC module is also refused to reply and is authorized.
Embodiment three is applicable to that (2) plants negotiation mode.Plant negotiation mode for (2), because the state information that the cell that each port sends all can carry all of the port, so when the up subport of some ports and descending subport all break down, for example fault has all taken place in first of the first port up subport 111 and the first descending subport 121, SC module 3 can detect the first up subport 111 and break down, and a SMe submodule 12 can detect the first descending subport 121 and break down.After SC module 3 detects the first up subport 111 and breaks down, SC module 3 sends cell to a SMe submodule 12 by the first descending subport 121 and the second descending subport 122 that is connected with SC module 3, carry the information that the first up subport 111 breaks down in the cell, the one SMe submodule 12 sends to a SMi submodule 11 with the information that the first up subport 111 breaks down, and such SMi submodule can know that the first up subport breaks down.At this moment, when a SMe submodule 12 detects the first descending subport 121 and breaks down, the information that the first descending subport 121 is broken down sends to a SMi submodule 11, the one SMi submodule 11 sends cell to SC module 3 by other the up subports that are connected with a SMi submodule 11 except that the first up subport, carry the information that the first descending subport breaks down in the cell, the information that notice SC module 3 first descending subports 121 break down.Like this, SC module 3 just can know that the first descending son end fault has taken place also by 121 mouthfuls.For the SMi submodule that sends request by the first up subport 111, SC module 3 refusals are replied and are authorized.For sending the SMi submodule that requires to send by the first descending subport 121 cell, SC module 3 is also refused to reply and is authorized.
Be illustrated in figure 5 as port fault processing method embodiment four flow charts of the present invention, comprise:
Step 402, the requirement that sends for the SMi submodule are by the request of the first descending subport transmit cell, and SC module refusal is replied and authorized.For the request that sends by the first up subport, SC module refusal is replied and is authorized.
Embodiment four described methods are applicable to that (1) plants negotiation mode.Plant negotiation mode for (1), because the state information that the cell that each port sends all can only carry port self, the state information that the cell that sends by each port can not carry other ports except that described port self, at this moment, if fault has all taken place in the up subport of a certain port and descending subport, the SC module can detect up subport fault has taken place, the SMe submodule that links to each other with descending subport can detect descending subport fault has taken place, but the information that the SMe submodule can't mode through consultation breaks down descending subport sends to the SC module.For this situation, fault has taken place when the SC module detects up subport, think simultaneously that then fault has also taken place the descending subport of described port, the requirement that sends for the SMi submodule is by the request of described descending subport transmit cell, the SC module is also refused to reply and is authorized, for the request that the SMi submodule sends by the up subport that breaks down, also refusal is replied and is authorized.
Particularly, for structure as shown in Figure 1, if fault has all taken place in the first up subport 111 and the first descending subport 121, at this moment SC module 3 can detect the first up subport 111 fault has taken place, the one SMe submodule 12 can detect the first descending subport 121 fault has taken place, but a SMe submodule 12 can't mode through consultation be notified the SC module information that 3 first descending subports 121 break down, and then fault has also taken place the SC module 3 acquiescences first descending subport 121.If a SMi submodule 11 sends request to SC module 3 by the first up subport 111, then because fault has taken place SC module 3 known first up subports 111, SC module 3 refusals are replied and are licensed to a SMi submodule 11.If when the 2nd SMi module 11 sends the request that requires by first descending subport 121 transmit cells to SC module 3 by the 3rd up subport 211, because fault has taken place the SC module 3 acquiescences first descending subport 121, SC module 3 is also refused to reply and is licensed to the 2nd SMi submodule 12.The 2nd SMi submodule 12 can not receive the mandate of SC module, then the 2nd SMi submodule 12 can judge that fault has taken place the 3rd up subport 211, or first descending subport 111 fault has taken place, or fault has all taken place in the two, then the 2nd SMi submodule 12 is selected to send request to SC module 3 by other the up subports that are connected with the 2nd SMi submodule 12 except that the 3rd up subport 211, and requires to adopt other the descending subport transmit cells that are connected with the SC module except that the first descending subport 111 in described request.Wherein, other up subport should be the up subport that is connected with the 2nd SMi submodule 12, for example can be the 4th up subport 212; Other descending subport can be the descending subport that is connected with SC module 3, for example the second descending subport 122 or the 3rd descending subport 222 or the 4th descending subport 221.
For aforementioned first and second kinds of situations, owing to have only one to break down in up subport and the descending subport, so no matter adopt which kind of negotiation mode, the SC module can be known the information that up subport and descending subport break down, so processing method that is adopted and negotiation mode are irrelevant.For the third situation, because fault has all taken place in up subport and descending subport, adopt (1) kind negotiation mode can cause the SC module can't know the information that descending subport breaks down, so at different negotiation modes, the processing method difference of employing.
Among the method embodiment provided by the invention, for the Crossbar port that breaks down, for the request that sends by the port that breaks down, perhaps require to use the request of the port transmission cell that breaks down, the SC module is all refused to reply and is authorized, the SMi submodule is after the mandate that can not receive from the SC module, can select other port to send request, or transmission requires to use the request of other port transmission cells, so just the portmask that breaks down can be fallen, do not re-use the Crossbar port that breaks down, thereby need not dispose the SMi submodule, reduced system complexity, and the information that port breaks down can improve response speed by the transmission of the hardware port that does not break down between SC module and SMe submodule or SC module and the SMi submodule.
The embodiment of the invention also provides a kind of port failure treatment system, be illustrated in figure 6 as port failure treatment system embodiment one structural representation of the present invention, described system comprises: SC module 3, SMi submodule 1 and SMe submodule 2, connect by at least two up subports between SC module 3 and the SMi submodule 1, connect by at least two descending subports between SC module 3 and the SMe submodule 2, for convenience of explanation, two up subports and two descending subports shown in Fig. 2 are respectively the first up subports 111, the second up subport 112, the first descending subport 121 and the second descending subport 122.A kind of operation principle of described system is:
When SC module 3 detects the first up subport 111 between SMi submodule 1 and the described SC module 3 and breaks down, the request that SC module 3 receives by the described first up subport 111 for SMi submodule 1, refusal is replied and is authorized; The request that SC module 3 receives by other the up subports that are connected with described SMi submodule 1 (i.e. the second up subport 112) except that the described first up subport 111 for SMi submodule 1 is replied and is authorized.
The another kind of operation principle of system shown in Figure 6 is:
When SMe submodule 2 detected the first descending subport 121 and breaks down, SMe submodule 2 sent information that the first descending subport 121 breaks down to SMi submodule 1; SMi submodule 1 sends cell to SC module 3, carries the information that the first descending subport 121 breaks down in the cell; For the request of the requirement that receives by first descending subport 121 transmit cells, SC module 3 refusals are replied and are authorized; For the request of the requirement that receives by other the descending subport transmit cells that are connected with SC module 3 except that the first descending subport 121, SC module 3 is replied and is authorized.
Another operation principle of system shown in Figure 6 is:
