Abstract

The invention discloses an IP over wavelength division multiplexing (WDM) network energy saving method for a router card under protection of SBPP. The method comprises the steps of performing traffic grooming on an IP over WDM network of the router card under the protection of SBPP, thus acquiring work light channels and protection light channels; and distributing each work light channel and each protection light channel to the router card, wherein a traffic grooming algorithm comprises respectively building idle virtual topologies Gw and Gp for a work virtual link and a protection virtual link in an IP layer, and then acquiring a business request DR from a request list; building a work path in the Gw; and building a protection path in the Gp until the protection channel meets all protection business requirements. The steps of distributing each work light channel and each protection light channel to the router card comprises distributing each working light channel and each protection light channel to the router card in a mixed mode and a dedicated mode. According to the method provided by the invention, sharing of united standby resources of an optical layer and the IP layer is achieved, and maximization of energy saving is achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing IP over WDM network energy saving based on router card sleep. Background technique [0002] Driven by the widespread deployment of electronic devices, information and communication technology activities (ICT) consume 2%-10% of the world's electricity output. The power consumption generated by the communication network cannot be ignored, so emphasizing energy saving is of great significance to the communication network. [0003] In addition, since the backbone network carries huge traffic, network protection is particularly important. Various protection techniques (eg, SBPP, 1+1 and p-cycles) have been applied in wavelength division multiplexing (WDM) optical networks. Among them, SBPP protection technology is considered as one of the most promising technologies because of its simple operation, fast recovery rate, and efficient spare capacity sharing...
