Virtual optical network reconfiguration method and system

Abstract

The invention relates to a virtual optical network reconfiguration method and system. The virtual optical network reconfiguration method comprises the following steps: acquiring a bandwidth demand matrix by using the optical layer controller; configuring the optical network device by taking meeting the bandwidth requirement matrix as a target, and determining an optimal topological structure with a management target; recommending the optimal topological structure with the management target to the IP network controller; judging whether the IP network controller accepts the optimal topological structure with the management target or not, and if so, executing the optimal topological structure with the management target; and if not, re-estimating the bandwidth demand matrix by using the optical layer controller until the IP network controller accepts the optimal topological structure with the management target. The resource utilization rate can be improved.

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...

[0008] The purpose of the present invention is to provide a virtual optical network reconfiguration method and system to solve tenants’ lack of understanding of the flexibility of the optical layer. Tenants often regard the flexible optical network as a static pipeline and cannot use the flexibility of the optical network, resulting in Low utilization of network resources caused by static network topology in virtual optical network
