Abstract

The invention relates to a virtual optical network reconfiguration method and system. The virtual optical network reconfiguration method includes: using the optical layer controller to obtain a bandwidth demand matrix; aiming at satisfying the bandwidth demand matrix, configuring the optical network equipment to determine an optimal topology structure with management objectives; The optimal topology structure with management objectives is recommended to the IP network controller; determine whether the IP network controller accepts the optimal topology structure with management objectives, and if so, execute the optimal topology structure with management objectives ; If not, use the optical layer controller to re-estimate the bandwidth requirement matrix until the IP network controller accepts the optimal topology structure with management objectives. The invention can improve resource utilization rate.

Description

technical field

[0001] The invention relates to the field of virtual optical network reconfiguration, in particular to a virtual optical network reconfiguration method and system. Background technique

[0002] Thanks to the advantages of low cost, large capacity, and low latency of optical networks, optical networks are widely used in telecommunication networks. Network topology represents the connection relationship between network nodes and the maximum carrying capacity of each connection. figure 1 It is the structural diagram of the telecommunication network, such as figure 1 As shown, the Internet Service Provider (Internet Service Provider, ISP) abstracts the complex underlying hardware facilities into a simple virtual optical network topology through the virtual optical network technology to provide transport services for the tenant's IP network, carry the tenant's IP traffic, and make the Multiple tenants can share the same physical optical network; in order to avoid...
