Description:
TECHNICAL FIELD 
       [0001]    The disclosure relates to the field of communications, and particularly to a service scheduling system, a service scheduling method, and a control device. 
       BACKGROUND 
       [0002]    A communication system comprises a plurality of service processing devices for processing services; after a certain service processing device has processed the service, it may need to schedule the processed service to other service processing devices for subsequent processing; in the prior art, a service scheduling device is generally adopted to schedule the service. 
         [0003]    As shown in  FIG. 1 , an existing service scheduling system comprises a service scheduling device  11  and at least two service processing devices  12 ; after the service processing device  12  has processed a service, it sends the service to the service scheduling device  11 , wherein the service is a service to be scheduled. The service scheduling device  11  is connected with the service processing devices  12  via a plurality of buses, and ports for connecting the buses on the service scheduling device  11  and the service processing devices  12  are called bus ports. 
         [0004]    One bus port comprises a plurality of transfer units, which are in one to one corresponding to transfer units in a connected bus port, so that the corresponding transfer unit can be determined as long as two connected bus ports are determined; for example, a service processing device A is connected with a service scheduling device a via two buses, comprising a bus  1  and a bus  2 , wherein a bus port A 1  in the service processing device A is connected with a bus port a 1  in the service scheduling device a via the bus  1 , and a bus port A 2  in the service processing device A is connected with a bus port a 2  in the service scheduling device a via the bus  2 ; all of the bus ports A 1 , A 2 , a 1  and a 2  comprise two transfer units respectively, wherein the bus port A 1  comprises a transfer unit A 11  and a transfer unit A 12 , the bus port A 2  comprises a transfer unit A 21  and a transfer unit A 22 , the bus port a 1  comprises a transfer unit a 11  and a transfer unit a 12 , and the bus port a 2  comprises a transfer unit a 21  and a transfer unit a 22 , then a corresponding relationship among the transfer units is shown in Table 1:

                 TABLE 1 
               
               
                   
                   
               
             
             
               
                   
                 Transfer unit A11 
                 Transfer unit a11 
               
               
                   
                 Transfer unit A12 
                 Transfer unit a12 
               
               
                   
                 Transfer unit A21 
                 Transfer unit a21 
               
               
                   
                 Transfer unit A22 
                 Transfer unit a22 
               
               
                   
                   
               
             
          
         
       
     
         [0005]    that is, the transfer unit A 11  in the service processing device A sends the service to be scheduled to the transfer unit a 11  in the service scheduling device a via the bus  1 , the transfer unit A 12  in the service processing device A sends the service to be scheduled to the transfer unit a 12  in the service scheduling device a via the bus  1 , and the rest may be deduced by analogy. 
         [0006]    In addition, a scheduling rule for the service scheduling device to schedule the services can be pre-configured, for example, the following rule is preset: 
         [0007]    a service to be scheduled sent by the transfer unit A 11  in the bus port A 1  of the service processing device A is scheduled to a transfer unit B 24  in a bus port B 2  of a service processing device B. 
         [0008]    If the service scheduling device a receives the service to be scheduled from the transfer unit A 11  in the bus port A 1  of the service processing device A, it can be seen from the above-mentioned preset scheduling rule that, the service needs to be scheduled to the transfer unit B 24  in the bus port B 2  of the service processing device B, at the moment, the service scheduling device a needs to send the service to be scheduled to the transfer unit B 24 , so the service scheduling device a must learn from which transfer unit of the service scheduling device a the service is sent, that is, it needs to determine the transfer unit corresponding to the transfer unit B 24  from all the transfer units of the service scheduling device a; therefore, the service scheduling device a needs to learn the corresponding relationship among the transfer units of the service scheduling device a and the transfer units in the service processing devices, i.e., the corresponding relationship among the transfer units in the service scheduling system. 
         [0009]    In the prior art, the corresponding relationship among the transfer units is generally written into software codes of the service scheduling device; when scheduling a service, the service scheduling device can directly search the corresponding relationship for a transfer unit of the service scheduling device to send the service according to the transfer unit to which the service needs to be scheduled, and then the service scheduling device sends the service to the transfer unit to which the service needs to be scheduled based on the searched transfer unit; if a connection status of the bus ports in the service scheduling system is changed, for example service processing devices are added, bus ports of the service processing devices or service scheduling devices are added, connection relationship among bus ports are changed and the like, the corresponding relationship among transfer units stored in the service scheduling devices needs to be updated at the moment, so the software codes of the service scheduling device must be modified, however, it needs to consume many resources to modify the codes due to a large number of software codes stored in the service scheduling device, which results in poorer expansibility of the service scheduling system and lower processing efficiency of the system.

       [0010]    In view of the above problem, embodiments of the disclosure provide a service scheduling system, a service scheduling method and a control device so as to solve the problem in the prior art that modifying software codes when a corresponding relationship among transfer units is updated thereby resulting in poorer expansibility of the service scheduling system and lower processing efficiency of the system.

     DETAILED DESCRIPTION 
       [0038]    The main implementation principle, a specific implementation method and beneficial effects that can be achieved correspondingly by technical solutions of embodiments of the disclosure will be described in detail with reference to the drawings. 
         [0039]      FIG. 2  shows a schematic diagram of a structure of a service scheduling system in an embodiment of the disclosure, wherein the service scheduling system comprises a control device  21 , a service scheduling device  22  and at least two service processing devices  23 , and the service scheduling device  22  is connected with the service processing devices  23  via bus ports, wherein 
         [0040]    the control device  21  is configured to obtain connection status information of each bus port in the service scheduling system respectively, update a first corresponding relationship among transfer units in the service scheduling device  22  and transfer units in the service processing devices  23  according to the obtained connection status information of the bus port when judging that the changed connection status information is obtained, and send the updated first corresponding relationship to the service scheduling device  22 ; 
         [0041]    the service scheduling device  22  is configured to receive the updated first corresponding relationship sent from the control device  21 , and schedule services to be scheduled sent from the service processing devices  23  respectively according to the updated first corresponding relationship; and 
         [0042]    the service processing device  23  is configured to send the services to be scheduled to the service scheduling device  22 , and process the services scheduled by the service scheduling device  22 . 
         [0043]    It can be seen from the above processing procedure that, in the technical solutions of the embodiments of the disclosure, the control device is added to the service scheduling system, and the control device obtains the connection status information of the bus port in the service scheduling system respectively, updates the first corresponding relationship among the transfer units in the service scheduling device and the transfer units in service processing devices according to the obtained connection status information of the bus port when judging that the changed connection status information is obtained, and sends the updated first corresponding relationship to the service scheduling device to enable the service scheduling device to schedule the services to be scheduled without modifying software codes in the service scheduling device anymore according to the updated first corresponding relationship, so that expansibility of the service scheduling system and processing efficiency of the system are effectively improved. 
         [0044]    Based on the service scheduling system as shown in  FIG. 2 , an embodiment of the disclosure provides a service scheduling method, as shown in  FIG. 3 ; the specific processing procedure is as follows. 
         [0045]    Step  31 : the control device obtains connection status information of each bus port in the service scheduling system respectively; 
         [0046]    wherein the bus port can be in either a working status or an idle status; if the bus port is in the idle status, the connection status information of the bus port comprises information for identifying that the bus port is in the idle status; if the bus port is in the working status, the connection status information of the bus port comprises information for identifying that the bus port is in the working status, and identification information of a bus port connected with the bus port. 
         [0047]    For example, if a bus port A 3  is in the working status and is connected with a bus port a 4 , the connection status information of the bus port A 3  can be: the bus port being in the working status and connected with the bus port a 4 ; and the connection status information of the bus port a 4  is: the bus port being in the working status and connected with the bus port A 3 . 
         [0048]    In an embodiment of the disclosure, the control device can directly detect the connection status information of the bus port in the service scheduling system, or can receive passively, for example, a network manager sends the connection status information of the bus port in the service scheduling system to the control device. 
         [0049]    Step  32 : the control device judges whether the changed connection status information is obtained in step  31 ; 
         [0050]    if the bus port A 3  of the service processing device A is connected with the bus port a 4  of the service scheduling device before the control device obtains the connection status information, but the bus port A 3  is no longer connected with the bus port a 4  and connected with the bus port a 3  after the control device obtains the connection status information, then the connection status information of the bus port A 3  at the moment is: the bus port being in the working status and connected with the bus port a 3 , therefore, the connection status information of the bus port A 3  is changed, and meanwhile the connection status information of both the bus port a 4  and the bus port a 3  is changed. 
         [0051]    Step  33 : if the judging result of step  32  is yes, the first corresponding relationship among the transfer units in the service scheduling device and the transfer units in the service processing devices is updated according to the obtained connection status information of the bus port; 
         [0052]    wherein the process that the control device updates the first corresponding relationship can be and not intended to limit the follows: 
         [0053]    the control device firstly obtains a second corresponding relationship among the transfer units in the service processing devices and the bus ports in the service scheduling system, determines a third corresponding relationship among the bus ports in the service scheduling system according to the obtained connection status information of the bus ports, and updates the first corresponding relationship among the transfer units in the service scheduling device and the transfer units in the service processing devices according to the second corresponding relationship and the third corresponding relationship. 
         [0054]    For example, if the connection status information of the bus port obtained by the control device is: the service processing device A and the service processing device B being connected with the service scheduling device a respectively, the bus ports A 1  and A 2  of the service processing device A being connected with the bus ports a 2  and a 3  of the service scheduling device respectively, and the bus ports B 1  and B 2  of the service processing device B being connected with the bus ports a 1  and a 4  of the service scheduling device respectively, then the third corresponding relationship among the bus ports in the service scheduling system can be and not intended to limit Table 2.

         [0055]    If the control device needs to determine the corresponding relationship among the transfer units, it also needs to learn the second corresponding relationship among the transfer units in the service processing devices and the bus ports in the service scheduling system, that is, it needs to obtain the corresponding relationship among the transfer units in the service processing device A and the bus ports A 1  and A 2 , and the corresponding relationship among the transfer units in the service processing device B and the bus ports B 1  and B 2 . The corresponding relationship among the transfer units in the service processing device A and the bus ports can be and not intended to limit Table 3.
