Abstract

The invention discloses a monitoring trail generation joint optimization method in consideration of wavelength allocation in an all-optical network. In the design process of a link failure monitoring system based on monitoring trails, the number of monitors is considered, the consumption of a wavelength resource is brought into the calculation of the total cost, and the number of monitoring trails borne by a single link is added to the constraint condition of monitoring trail generation, so that for the monitoring trails, the links bearing a few monitoring trails are preferably selected; meanwhile, the algorithm is further combined with a layered graph model, and an alternative monitoring set is increased, so that the learnt search space is enlarged, the number of monitoring trails borne by the single link is obviously lowered, and the total cost of the monitoring system is further reduced after the resource optimization algorithm. Under the condition that the cost ratio of the wavelength resource is high, the optimization effect is more obvious, and the total cost of the link failure monitoring system can be furthest reduced.

Description

technical field [0001] The invention belongs to the technical field of all-optical networks with wavelength division multiplexing, and more specifically relates to a combined optimization method for generating monitoring traces combined with wavelength distribution in all-optical networks. Background technique [0002] Since the development of the communication network, the all-optical network using wavelength division multiplexing technology has become the main trend of the current communication network development. However, all-optical networks have a very big disadvantage, that is, they are easily damaged and are very sensitive to damage. Then we must study a set of effective solutions for this situation, in order to achieve the goal of quickly locating the failed link. In an all-optical network, a traditional method for monitoring a failed link is a channel-based or link-based method. Subsequently, the researchers proposed a design that uses a monitoring cycle at the p...
