  • Virtual optical network-oriented spectrum resource trading method and system
    Patent number: 11451890
    Abstract: The invention provides a virtual optical network-oriented spectrum resource trading method and system. The method includes: after virtual optical networks are constructed according to a preset topological structure, in different time slots, controlling, based on capacity demand information of virtual links of the virtual networks, cumulative credit values of the virtual optical networks, and a preset credit threshold, the virtual links between the virtual optical networks to trade spectrum resources of a common physical link, to implement that the virtual optical networks trade spectrum resources according to a real-time capacity demand.
