Embodiment
As shown in Figure 1, in switching system, with message switching equipment 1 is that the center is connected with a plurality of switching equipment 2, each switching equipment 2 can carry out information exchange by switch 1, according to system and method for the present invention, each equipment 2 to link information switch 1 distributes a unique real address for example A, B, C, D and E respectively, and for example a1, a2, a3, c label with a virtual address respectively to each application in the switching system.Connection solid line among the figure is represented being connected of switching equipment and switch, and dotted line is represented real address equipment and the virtual address corresponding relation between using.When a real address is distributed in a virtual address, then expression applications (switching task) appointment that this virtual address is represented is finished by a switching equipment of real address correspondence, when several virtual addresses being distributed to a real address, mean that then the several switching tasks that the virtual address is represented specify an equipment of being represented by this real address to finish.In other words, between virtual address and the real address can be the mapping relations of many-one, one-to-many and multi-to-multi.At any time, virtual address can corresponding a plurality of real addresses, and real address can corresponding a plurality of virtual addresses, like this, have just formed the mapping relations of corresponding a plurality of virtual addresses, a plurality of real addresses in this system.As shown in Figure 1, the real address is to have three to use a1, a2, a3 on the switching equipment of A, and exchange use a1 corresponding simultaneously switching equipment A and switching equipment D, use a2, a3 except that being connected in the represented switching equipment of real address A, also be connected in the represented switching equipment of real address C, use c and also finish by real address B and the represented switching equipment of D simultaneously.Can understand the situation of equipment and application in order to make switch, be provided with an exchange record sheet at switch, this table stores the real address of all switching equipment that are connected in message switching equipment 1 and corresponding with it passes through the virtual address that message switching equipment 1 carries out the application of information exchange, and corresponding relation and the busy-idle condition of virtual address and the normal/abnormal state of real address between real address and the virtual address have been shown, as shown in the table, following table has been listed the example of the exchange record sheet that concerns between real address among Fig. 1 and virtual address.
| The real address | The virtual address | The virtual address state | The real address state |
| A | a1 | Idle | Normally |
| A | a2 | Busy | Normally |
| A | a3 | Idle | Normally |
| B | c | Idle | Normally |
| C | a2 | Idle | Normally |
| C | a3 | Busy | Normally |
| D | a1 | Idle | Normally |
| D | c | Busy | Normally |
| E | a3 | - | Unusually |
Particularly, each in the above-mentioned table comprises whether real address, virtual address and virtual address be busy/idle state and real address normal state whether.Switch when operation, can institute move the virtual address of using and the real address of moving the equipment of this application according to the configuration of switching system and be added to together and exchange in the record sheet.More particularly, when the exchange of the application of the application of a virtual address a1 of switch operation and another one virtual address c, switch is at first checked the exchange record of virtual address c in the exchange record sheet, message switching equipment is checked through record two that comprise virtual address c in the table, respectively to there being the real address that B and D are arranged, and B pairing virtual address c in real address is in idle condition, and D pairing virtual address c in real address is in busy state, therefore, the application that message switching equipment will be represented virtual address a1 according to this state exchanges by the represented application of the represented switching equipment of real address B and virtual address c, and does not carry out exchange (because it is busy) between the represented application of virtual address a1 and c by the represented switching equipment of real address D.Certainly, pairing virtual address c all is in idle condition if message switching equipment is checked through real address B, D, then the exchange between the represented application of virtual address a1, c both can exchange by the represented switching equipment of real address B, also can exchange by the represented switching equipment of real address D.For can being detected, switch exchanges unusually and makes alignment processing; also keep a normal or unusual operating status record of each real address corresponding device of record; occur when unusual when detecting certain real address corresponding device; to the information translation of exchange be comprised the represented switching equipment in the real address that is in normal condition of this virtual address to other according to the operating status record in the described exchange record sheet.In the time of will carrying out information exchange with the represented application of virtual address a3 such as the represented application of virtual address a2, message switching equipment is checked through the pairing virtual address a3 of real address A and is in idle condition, C pairing virtual address a3 in real address is in busy state, and the real address E that virtual address a3 should be arranged is in abnormality, therefore, message switching equipment will be arranged the represented application of the represented application of virtual address a2 and virtual address a3 is carried out information exchange by real address A.
The speed buffering bunkerage that has the exchange message deposited in the message switching equipment, this speed buffering bunkerage is divided into each speed buffering storage area that group is empty, the real address indicates, be that each has a speed buffering storage area to empty, real address combination, be equivalent to each constituting the slow storage area of a high speed between void, the real address; The idle busy state of the application that the virtual address is represented is then judged according to data volume size in the speed buffering storage area or message number.When exchanging, decision maker in the message switching equipment is then judged data quantity stored size or message number in the high-speed buffer of each void, real address correspondence, therefrom select the high-speed buffer that data volume is few or the message number is less, promptly comparatively idle virtual address, the information that will exchange is put into this idle speed buffering storage area, and reset state and revise the exchange record sheet according to the situation of speed buffering storage area, from this speed buffering storage area, information exchange is given the application of the virtual address correspondence on this real address then.The idle busy state of virtual address can be provided with a boundary to the amount of information size of its corresponding high-speed buffer or message number to be determined, is busy on this boundary, then is idle condition under boundary.As previously mentioned when the application of the application of virtual address a1 and virtual address c exchanges, message switching equipment finds the corresponding of virtual address c and the corresponding of real address B and virtual address c and real address D, and judge the amount of information or the message number of the cache memory section between these two correspondences, amount of information in cache memory section corresponding between virtual address c and the real address B is less or the message number is less, and the big or message number of the amount of information in the corresponding cache memory section is more for a long time between virtual address c and the real address D, message switching equipment will be put into corresponding cache memory section between virtual address c and the real address B to the information that will exchange between virtual address a1 and the virtual address c, information be sent to the application of the virtual address c correspondence on the B of real address then from this speed buffering storage area.By this actual situation address designation, thereby realized load balancing, make that message switching equipment can be according to virtual address and application (equipment) state (busy not busy), from a plurality of real addresses of virtual address correspondence, select suitable device to exchange, reach the equipment of link information switch or the load balancing of application.
