In the above embodiment of the present invention, the maintenance of polymerization forward table comprises determining that the available physical ports that aggregated links port is corresponding, and calculate this member device to the distance value in the path of member device belonging to each available physical ports, generate according to distance value and safeguard polymerization forward table.
In a particular embodiment of the present invention, each member device before generating and safeguard respective polymerization forward table according to distance value, can first judge whether the physical port of configuration belongs to same member device, if the physical port of configuration is the aggregated links port of striding equipment, the distance value in the path of each member device is then arrived with this member device that concrete physical port is this device storage of keyword query, and according to distance value mode from small to large, the physical port of each member device is ranked up, each member device creates according to the physical port order after sequence and fills in polymerization forward table, if the physical port of configuration is not the aggregated links port of striding equipment, then this physical port is not ranked up.
Further, in the above embodiment of the present invention, it is determined that the step of the available physical ports that aggregated links port is corresponding includes: obtain the Fisrt fault information of the member device that pile system detects；The available physical ports that aggregated links port is corresponding is determined according to Fisrt fault information.
In a particular embodiment of the present invention, the faults itself testing mechanism of pile system can detect whether that member device breaks down, if detecting, certain member device breaks down, whether the polymerization forward table of all member devices inquiry oneself then exists the physical port of the member device broken down, if there is the physical port of the member device broken down, then all physical ports of the member device broken down all are deleted, so that it is determined that go out the available physical ports that aggregated links port is corresponding, recalculate this member device again and arrive the distance value in the path of member device belonging to each available physical ports, and according to distance value order from small to large, residue physical port is ranked up, thus generating and safeguard new polymerization forward table.
In the above embodiment of the present invention, the maintenance of polymerization forward table also includes: obtain the second fault message of the physical port that pile system detects；According to the second fault message, update the available physical ports that aggregated links port is corresponding, and the distance value in the path of member device generates and safeguard polymerization forward table belonging to each available physical ports after this member device to renewal.
In a particular embodiment of the present invention, the faults itself testing mechanism of pile system can detect whether that physical port breaks down, if there being physical port to break down, then whether the polymerization forward table of all member devices inquiry oneself exists the physical port broken down, if occurring the physical port of fault, then this physical port broken down is deleted from polymerization forward table, and according to distance value order from small to large, each physical port remaining is ranked up, thus generating and safeguard new polymerization forward table.
In the above embodiment of the present invention, the maintenance of polymerization forward table also includes: record the precedence information that each available physical ports is corresponding；Polymerization forward table according to this plant maintenance, selects the first physical port that shortest path is corresponding, including: according to the precedence information of available physical ports, select the first kind physical port with limit priority；The first physical port that shortest path is corresponding is selected from first kind physical port.
In a particular embodiment of the present invention, the precedence information of user's whether configuration member's device forwards can be detected, if being configured with the precedence information of forwarding, will according to user configured precedence information, according to priority order from high to low, each available physical ports is ranked up, certainly, for being configured without the physical port of priority, according to the distance value in above-mentioned path order from small to large, physical port can be ranked up, thus obtaining new polymerization forward table, data message forwarding can be gone out by member device according to user configured precedence information.Certainly, if the first kind physical port of limit priority has multiple physical port, it is possible to select the first physical port that shortest path is corresponding to carry out forwarding data packets from first kind physical port.
In a particular embodiment of the present invention, also illustrating for examples detailed above, when user is in order to accurately control converting flow, realize by configuring the forwarding priority of each member device on member device, number is more big, and priority is more high.Assuming that it is 2 that user configures the priority of device A on device B, the priority of equipment B is 3, and equipment C priority is 1, then on device A, equipment B and equipment C, Trunk table is arranged respectively as shown in table 8, table 9 and table 10.Trunk table on member device A and C is still the Trunk table above calculated according to shortest path, and the Trunk table on equipment B is first according to prioritization, according still further to the Trunk table that shortest path sequence draws.So when the outgoing interface of the flow of access arrangement B is aggregated links port, first calculating interface from high priority physical port, obtaining outgoing interface is B1 or B2, and flow from then on interface forwards.After B1 and B2 link breaks down, the Trunk table of device A, equipment B and equipment C arranges respectively as shown in table 11, table 12 and table 13, at this moment the flow of access arrangement B finds out interface from the equipment that priority is 2 and obtains A1, flow forwards from A1, thus having reached the purpose forwarded according to priority accurate flow control.Simultaneously the flow on device A and C forwards and still forwards according to shortest path, decreases taking stacking bandwidth.
