specific example

[0095] Give a specific example to intuitively illustrate the principle of the above method:

[0096] First traverse each host to get all possible paths from node N1 to node N16:

[0097] D(N1-N2-N3-N5-N6-N11-N16)

[0098] D(N1-N2-N3-N4-N6-N11-N16)

[0099] D(N1-N2-N3-N4-N10-N16)

[0100] D(N1-N2-N3-N4-N10-N15-N16)

[0101] D(N1-N2-N3-N4-N10-N11-N16)

[0102] D(N1-N2-N9-N14-N10-N16)

[0103] D(N1-N2-N9-N14-N10-N11-N16)

[0104] D(N1-N2-N19-N18-N20-N15-N16)

[0105] D(N1-N7-N12-N17-N19-N18-N20-N15-N16)

[0106] D(N1-N7-N12-N8-N9-N14-N10-N15-N16)

[0108] D(N1-N2-N8-N19-N18-N20-N15-N16)

[0109] D(N1-N7-N12-N8-N9-N14-N10-N16)

[0110] ...

[0111] Among them, the two paths with the least number of nodes:

[0112] D(N1-N2-N9-N14-N10-N16)

[0113] D(N1-N2-N3-N4-N10-N16)

[0114] Assume that combined with the screening of the aforementioned feasible paths, it is found that the link N9-N14 cannot bear a large load, and th...

Abstract

The invention discloses a service path selection method, an SDN controller, a storage medium and electronic equipment, which are applied to an optical transmission network of an SDN architecture. Themethod comprises the following steps of traversing the optical transmission network according to a predetermined source node and a predetermined destination node in order to obtain a corresponding network topology; determining the communication capability of a direct connection link between every two adjacent nodes in the optical transmission network according to the network topology, and calculating a weight value of the direct connection link; screening a feasible path from each path between the source node and the destination node, wherein the weight value of each direct connection link contained in the feasible path meets the service load requirement; and selecting the shortest path in each feasible path as a service path. The whole network topology resources are effectively managed through the SDN architecture, the communication capability is expressed through the weight value of the calculated link, and the available path can be further screened through the weight value, so thatthe consumption resources of the routing calculation are reduced, and the network operation speed is improved; and the weight value can also be used for load balancing to achieve a purpose of balancing the load of the whole network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a service path selection method, an SDN controller, a storage medium and electronic equipment. Background technique [0002] Nowadays, people are facing tens of types and millions of devices in the network system, and the network devices are still multiplying. Therefore, it is necessary to solve problems such as different services, access methods, quality, and security to alleviate network pressure. Binding a large number of control protocols to specific forwarding protocols is a common pattern in traditional networks, thus forming the integration of control and forwarding. This method will lead to more bloated equipment, slow performance improvement, and difficulties in business development. [0003] On the other hand, there are many types of MAN services (10 / 40 / 100 / 200 / 400G or higher transmission speed network, not limited to this), and the network layer and topology a...
