Example Embodiment
[0147] (1) Example 1: When a service exists in the network
[0148] Suppose that the client C1 initiates a service request to the server S1, and S1 provides services to the client C1 through the forwarding group. Use wireshark to capture and analyze service data packets on ports N7-eth3, N7-eth4, and N7-eth5. The result showed that only the data packet sent to C1 was captured in N7-eth5. N7-eth5 is connected to the N4-eth2 interface, and there is only one single link from the routing component N4 to the client C1 that can transmit data, so the route adapted by the resource manager for the (S1, C1) service is [N7, N4, N2, N1].
Example Embodiment
[0149] (2) Embodiment 2: When the service path fails
[0150] When the (S1, C1) service is in the transmission process, if the link fails, the link needs to be restored as soon as possible or find a backup path in the shortest time to ensure the stability and reliability of service transmission. In this flexible transmission method, because the resource manager calculates the K shortest paths in the routing adaptation stage before the service transmission, in addition to sending the optimal path to the routing component, the remaining K-1 edges are stored in In paths, when the link is disconnected, the resource manager will issue the optimal path among the K-1 paths to the routing component, and there is no need to calculate the path through state awareness. On the one hand, it reduces the burden on the resource manager. On the other hand, it also minimizes the impact of failures on services.
[0151] Through the functional test in the previous step, it is known that the transmiss...
Example Embodiment
[0152] (3) Embodiment 3: When there are two services in the network
[0153] If (S1, C1) services already exist in the network, C2 also initiates a service request to server S2 at this time, and S2 provides services to C2 by adapting to the network group. Because the path [N7, N4, N2, N1] is already occupied by (S1, C1), the resource manager will calculate the optimal path according to the current network status. By capturing packets on the N7-eth3, N7-eth4, and N7-eth5 ports, the data packets sent to C2 are captured on the N7-eth3 port. Because there is only one link between the routing components N7 and N6, it can be determined that S2 is sending The service data to C2 is transmitted through the path [N7, N6, N3, N1], and the resource manager is (S2, C2). The service adaptation path is [N7, N6, N3, N1].
[0154] (4) Embodiment 4: When there are three services in the network
[0155] Two services (S1, C1) and (S2, C2) already exist in the network. At this time, C3 initiates a serv...
