Step 230, determining at least one communication path in the communication network diagram according to the frequency modulated service.

Specifically, the source node and the target node may be determined in the communication network diagram according to the fm service, and paths respectively connecting the source node and the target node in the communication network diagram may be used as communication paths, which may be understood that, due to the complexity of the structure of the communication network diagram, the number of communication paths determined according to the fm service may be multiple.

Where the segment stack may be a routing tag in the form of a stack data structure, each layer of the segment stack may store a node in the transmission path, and each time a communication node is reached based on the segment stack, the segment stack may pop information of the communication node from the segment stack.
In the embodiment of the invention, the information transmission paths can be respectively stored in each layer in the segment stack in the form of communication nodes, and the segment stack stored with the information transmission paths can be used as a routing label. For example, the information transmission path may be R1- > R3- > R5- > R2, see fig. 4, and one communication node may be stored per layer of the segment stack as a routing label.
Step 270, the service request is sent to each communication node along the information transmission path according to the routing label, so as to realize the transmission of the service request.
Specifically, the service request may be sequentially sent to the corresponding communication node according to the information in the routing label, and the service request may be sent along the information transmission path. Fig. 5 is an exemplary diagram of a segment route provided in the second embodiment of the present invention, referring to fig. 5, the information transmission path saved in the segment route in the embodiment of the present invention is specifically R1- > R3- > R5- > R6- > R7, and the service request may be forwarded sequentially along the communication node in the information transmission path, when the service request reaches the R3 node, the segment route pops R3 from the segment stack, uses the information of R5 to send the service request to R5, and repeats this process until the service request reaches the destination node R7, thereby implementing the transmission process of the service request.

Fig. 6 is an exemplary diagram of a segment routing information transmission method according to a second embodiment of the present invention, referring to fig. 6, taking a communication network of a virtual power plant as a software-defined network as an example, a process for performing information based on segment routing in the communication network may include the following steps:
step a: defining some QoS requirements required by the virtual power plant frequency modulation service, wherein the QoS requirements comprise: delay, bandwidth, hop count, and jitter. Delay: the time required to propagate through the network may affect QoS from one host to another. Bandwidth: traffic is forwarded to the maximum bandwidth of the requesting host without reducing the traffic rate in the path. Hop count: a minimum number of paths between the source node and the destination node. Dithering: one of the quality problems affecting the quality of the data packets.
Step b: and searching a communication path meeting QoS requirements of the frequency modulation service of the virtual power plant in the SDN. Firstly, when a virtual power plant user needs bandwidth, the user identification, the destination and the bandwidth requirement can be sent to an SDN controller through a bandwidth request data packet, and the method for determining the communication path specifically comprises the following steps:
step b-1: given a virtual power plant network graph G (V, E), in whichCapacity C of storage edge E V represents nodes in the virtual power plant, E represents communication links between the nodes, and B wu Is the bandwidth delay in the bandwidth request data packet and the edge utilization m E Can be obtained by the formula (1).
Step b-2: determining the minimum bandwidth B of the link according to the formula (2) wp For each communication link E, its corresponding available bandwidth resource is C E -B wu . Can be based on the minimum bandwidth B wp And equation (3) determining the maximum available bandwidth B between the source node Ps and the destination D wa Available will maximum available bandwidth B wa The corresponding path serves as a communication path.
B wp ＝min 1≤i≤n (C E -B wu ) (2)
B wa ＝max p∈Ps→D min 1≤i≤n (C E -B wu ) (3)
Step C: the SDN controller maps communication paths to segment networks. Segment routing provides efficient packet forwarding in a network path by specifying a list of segments. And after the segment route is configured, acquiring the segment route label according to the IGP protocol and redistributing the label in the segment route local network. Assume that the maximum available bandwidth path calculated by the SDN controller is R3-R5-R6-R7. Node R3 uses node SID 103 and sends the packet to R5. R5 pops up label 103 and sends the packet with label stack 105, 106, 107 to node R6. Node R6 knows that SID 105 is requested at its node. Thus, node R6 performs the requested service and pops the tag 105 out of the header. It forwards only packets with one label {107} to node R7. The switch informs the controller of the requested traffic of the frequency modulated service, and the controller obtains the network topology and determines the forwarding rules on the switch. The controller periodically notifies the switch of a message provided by the OpenFlow protocol to obtain available bandwidth information.
The communication network obtains the optimal path according to the maximum available bandwidth under the condition that the QoS requirement of the frequency modulation service of the virtual power plant is met in the process of carrying out information based on the segment route, and maps the optimal path to the segment, so that the forwarding of effective data packets in the network is ensured.
