Problems solved by technology
[0003] At present, there are many kinds of business in power distribution communication network, and the networked, interactive, and open levels of power distribution business are gradually increasing. It can only be in static operation mode, which brings serious challenges to the requirements of power network isolation, reliability, security and multicast management
In addition, the complexity of the traditional power communication network increases the difficulty of network management, which in turn leads to the vulnerability of the network
For example, if policies are issued across the entire network, administrators usually need to configure countless network devices and policy mechanisms. Consistent, so it is very easy to have policy non-compliance, network security degradation, etc. These are fatal factors for the operation of the smart grid, and have a great impact on the multi-service bearing and QoS guarantee capabilities, centralized and unified operation and maintenance and management and control capabilities of the distribution network communication system. , interface standardization and open capabilities put forward higher requirements

The invention discloses a virtual network mapping method for distribution network communication network fault self-healing, and the method comprises the steps: 1, calculating an alternative set CS (x,h) according to a physical topological structure of a distribution network communication network, and calculating the recoverability R (x) of a preset fault node x according to the state of a candidate node r in the alternative set CS (x, h); and step 2, generating a self-healing mapping rule by using a mixed integer rule according to the alternative set CS (x, h) and the recoverability R (x). The technical scheme of the invention is adopted; according to the invention, the method achieves the purpose of power distribution network optimization operation and self-healing control, enables backup resources to be shared in a power distribution network communication network, reduces the backup expenditure, improves the utilization rate of the backup resources, improves the survivability of thepower distribution network communication network to cope with multi-node faults, and achieves the purpose of minimizing the physical resources required by the mapping of a survivability virtual network.
Description
technical field [0001] The present application relates to the technical field of distribution network communication, in particular, to a virtual network mapping method for fault self-healing of distribution network communication network. Background technique [0002] The power distribution communication network is an important part of the smart grid construction of the State Grid Corporation of China. By promoting the construction of the appropriate distribution network communication system, especially the Ethernet Passive Optical Network (EPON), it effectively supports the operation of various smart power distribution services. . [0003] At present, there are many kinds of business in power distribution communication network, and the networked, interactive, and open levels of power distribution business are gradually increasing. It can only be in a static operation mode, which brings serious challenges to the requirements of power network isolation, reliability, security ...
