Problems solved by technology

[0002] Traditional distributed control based on synchronous digital sequences cannot meet the needs of fine-grained traffic monitoring in power communication networks
In addition, traditional smart grid routing path calculation methods seldom consider the application scenarios and requirements of power communication network expansion and survivability
When the power communication network needs to be expanded or fails, the forwarding path is still manually configured, resulting in a high configuration error rate, excessive human resources consumption, and slow expansion speed and failure recovery.

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The software-defined network for power data communication in this embodiment, such as figure 1 As shown, it includes client terminal host 1 and host 2, and also includes a centralized controller and 9 switches supporting the OpenFlow protocol; host 1 is responsible for sending data packets and host 2 is responsible for receiving data packets. Host 1 is equivalent to a substation in the power communication network, and host 2 is equivalent to a master station in the power communication network. Host 1 and host 2 are used to simulate the communication between the master station and the substation in the power communication network. Wherein, the centralized controller of this embodiment adopts NOX; adopts OpenvSwitch, combines with KVM virtualization platform to generate nine virtual switches supporting OpenFlow protocol. The IP ...

Abstract

The invention discloses a power communication network and a capacity expansion and destroy-resistant routing path determination method thereof, and belongs to the technical field of communication. The power communication network comprises a client terminal, a centralized controller and multiple switches which support an OpenFlow protocol. Application of a software defined network enables power data communication to obtain a global network view, so that high quality of service is ensured. Information interaction is carried out between the centralized controller and the switches which support the OpenFlow protocol; when the power communication network requires capacity expansion or is in fault, a forwarding path is configured automatically, a processing delay is reduced, the capacity expansion speed and fault recovery are speeded up, the configuration error rate is decreased greatly, and consumption of the manpower resource is reduced.

Description

technical field [0001] The invention belongs to the communication technology, in particular to an electric power communication network and a method for determining its capacity expansion and anti-destroy routing path. Background technique [0002] Traditional distributed control based on synchronous digital sequences cannot meet the needs of fine-grained traffic monitoring in power communication networks. In addition, traditional smart grid routing path calculation methods rarely consider the application scenarios and requirements of power communication network expansion and survivability. When the power communication network needs to be expanded or fails, the forwarding path is still manually configured, resulting in a high configuration error rate, excessive human resources consumption, and slow expansion speed and failure recovery. [0003] Software-defined networking enables administrators to conduct global control and monitoring of the power communication network throu...
