Fig. 6 is an exemplary diagram of a segment routing information transmission method according to a second embodiment of the present invention, and referring to fig. 6, taking a communication network of a virtual power plant as a software defined network as an example, a process of performing information based on segment routing in the communication network may include the following steps:
step a: defining some QoS requirements needed by the virtual power plant frequency modulation service, wherein the QoS requirements comprise: delay, bandwidth, hop count, and jitter. Delaying: the time required to propagate through the network may affect the QoS from one host to another. Bandwidth: the traffic is forwarded to the requesting host's maximum bandwidth without reducing the traffic rate in the path. Hop count: the minimum number of paths between the source node and the destination node. Dithering: one of the quality problems that affects the quality of the data packets.
Step b: and searching a communication path meeting the QoS requirement of the virtual power plant frequency modulation service in the SDN. Firstly, when a virtual power plant user needs bandwidth, a user identifier, a destination and the bandwidth requirement can be sent to an SDN controller by using a bandwidth request data packet, and determining a communication path specifically includes the following steps:
step b-1: given a virtual power plant network graph G (V, E), the tolerance C of a storage edge in the network graphEV denotes nodes in the virtual power plant, E denotes communication links between the nodes, and BwuIs bandwidth delay amount in bandwidth request data packet, edge utilization rate mECan be obtained by the formula (1).
Step b-2: determining the minimum bandwidth B of the link according to the formula (2)wpFor each communication link E, its corresponding available bandwidth resource is CE-Bwu. May be based on a minimum bandwidth BwpAnd equation (3) determines the maximum available bandwidth B between the source node Ps and the destination DwaThe maximum available bandwidth BwaThe corresponding path serves as a communication path.
Bwp＝min1≤i≤n(CE-Bwu) (2)
Bwa＝maxp∈Ps→Dmin1≤i≤n(CE-Bwu) (3)
And C: the SDN controller maps the communication path to a segment network. Segment routing provides efficient packet forwarding in a network path by specifying a segment list. An IGP protocol is set in the segment routing local network, and after the segment routing is configured, the segment routing label is obtained according to the IGP protocol and is redistributed in the segment routing local network. Assume that the maximum available bandwidth path calculated by the SDN controller is R3-R5-R6-R7. The node R3 uses the 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 from the packet header. It forwards only the packet with the label 107 to node R7. The exchanger informs the controller of the requested frequency modulation service flow, and the controller acquires the network topology and determines the forwarding rule on the exchanger. The controller periodically notifies the switch of a message provided by the OpenFlow protocol to acquire available bandwidth information.
The communication network carries out information process based on segment routing, under the condition that the QoS requirement of the frequency modulation service of the virtual power plant is met, the optimal path is obtained according to the maximum available bandwidth, the optimal path is mapped to the segment, and the forwarding of effective data packets in the network is guaranteed.
