A virtual backup capacity invulnerability protection method in energy-saving optical network

Abstract

The invention discloses a virtual backup capacity destroy-resistance protection method of an energy-saving optical network and belongs to the technical field of communication networks. The virtual backup capacity destroy-resistance protection method of the energy-saving optical network is based on the optical network sharing access protection mechanism. Each operating access and each protection (backup) access are respectively converged into different optical fibers in the energy-saving optical network with a sleep mode. Aiming at contradiction between access convergence restraint and link separating sharing restraint between operating accesses, the backup capacity of relevant links is expanded through a method that a virtual link capacity is arranged in the network. On the basis that requirements for network energy conservation and service protection average reliability are met, the blocking rate index of the destroy-resistant protection method of the energy-saving optical network can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of communication networks, and in particular relates to an anti-destruction protection method for virtual backup capacity in an energy-saving optical network. Background technique [0002] With the rapid development of communication and information technology and the explosive growth of Internet services, various communication devices with ultra-large capacity, ultra-high transmission rate, and ultra-fast processing speed have been continuously developed and applied to communication networks, which makes communication and information Energy consumption in the field continues to grow at an alarming rate.

Problems solved by technology

However, in an energy-saving optical network using sleep mode, in order to put as many non-working resources as possible into low-power sleep mode, the working channel and the protection channel are usually aggregated in different optical fibers, which will reduce the workload. The separation of links between channels reduces the chance of resource sharing, thereby degrading the resource utilization and blocking rate performance of the network, such as image 3 Shown: Using the energy-saving path protection method to establish two source nodes to the target node service connection, occupying 6 working wavelengths, 6 backup wavelengths, and 3 working mode optical fibers (which can be regarded as consuming 3 power units)
