Virtual resource slice management method and apparatus of power optical fiber access network

Abstract

The invention provides a virtual resource slice management method and apparatus of a power optical fiber access network. The method includes: receiving slice requests generated for users according tobusiness requests of different users by an optical network unit ONU; dividing an optical line terminal OLT of the power optical fiber access network into a plurality of virtual OLTs based on resourceinformation of the slice requests and the business requests of the users, and performing slice resource configuration according to the plurality of virtual OLTs to obtain a plurality of slice resources; and respectively distributing the plurality of slice resources to the users and / or businesses corresponding to the business requests of the different users. According to the method and apparatus, the physical OLT is divided into the plurality of virtual OLTs to realize slice configuration, different users or different businesses are divided into different network slices according to user requirements to satisfy differentiated network requirements of the users, business isolation is realized, the network reliability is improved, and the maximization of the utilization rate of the resources of the electric power optical fiber access network is realized.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a virtual resource slice management method and device for an electric optical fiber access network. Background technique [0002] While providing power transmission for users, power fiber-to-the-home can also transmit various control signals and network signals for users. Power Fiber To The Home (PFTTH) is an effective solution for four-network integration. The solution is to use the optical fiber medium in the optical fiber composite low-voltage cable OPLC to connect the communication office and users. OPLC is a composite cable with dual transmission capabilities of low-voltage power and optical communication, which can provide users with huge bandwidth access capacity. PFTTH's existing technical solutions include engineering construction of power fiber optic systems, power and information transmission on the same network based on OPLC power fiber optics,...
