Embodiment

[0113] Following the above technical solution, this embodiment provides a matching game-based multi-domain optical network traffic grooming method. Specifically, in a dynamic multicast environment, the multi-domain optical network traffic grooming method formed by the proposed MDMTG method is implemented through an example. The method is described by taking the communication networks of three different units as three different autonomous domains. Assuming that temporary video conferences are required between three units, given a multipoint-to-multipoint dynamic multicast request R = {2, 3, 9, 18; 4, 11, 17, 20}, it is required to guarantee the entire conference network smooth and reduce network costs as much as possible. Figure 4(a) shows the topological structure G=(23, 45) of the multi-domain optical network. According to the traffic size of each link in the optical network, a matching game is performed between the source node and the destination node in the multicast reques...

Abstract

The invention provides a multi-domain optical network traffic grooming method based on matching game, which comprises the following steps of: for a known multicast traffic request, performing a matching game by taking a source node and a destination node as game players to form optimal matching meeting preferences, and combining a game result with an optimized heuristic method, routing the trafficrequests on the constructed virtual topology, and finally obtaining a topological structure which meets all the traffic requests and enables the number of transceivers in the multi-domain optical network to be minimum. Under the condition of a multi-domain optical network, for the problem of processing a dynamic multicast flow request, especially under the conditions that the optical network structure is relatively complex, the multicast flow request is relatively large and the network cost needs to be reduced as much as possible, the smoothness of multi-domain optical network services can beeffectively guaranteed, and the resource utilization rate is improved.

Description

technical field [0001] The invention belongs to the field of optical networks, relates to multi-domain optical network flow grooming, and in particular to a matching game-based multi-domain optical network traffic grooming method. Background technique [0002] Existing IP traffic applications consume large amounts of bandwidth, forcing network operators to develop advanced technologies to overcome the inefficiencies of traditional wavelength division multiplexing (WDM) networks. These defects are caused by the allocation of the entire wavelength capacity without considering the bandwidth required for the connection, and the traffic grooming method is an effective way to solve this problem. Routing and Spectrum Allocation (RSA) occupies a very important position in optical networks, and it also faces routing, modulation level and spectrum allocation (RMSA) issues. Both static and dynamic traffic classifications are used in the RSA and RMSA methods. The goal of static traffi...
