A method and device for establishing a virtual access node in an optical access network

Abstract

The invention discloses a method and equipment for establishing a virtual access node in an optical access network, which helps to realize that the InP access node can be configured according to service requirements and improves configuration flexibility. The method includes: after receiving the first message from the user equipment, the access device in the first network acquires the identifier of the virtual line corresponding to the physical line, where the physical line is the physical line between the user equipment and the first network. A physical line between access nodes AN, the virtual line is a logical line between the user equipment and the virtual AN; the access device acquires the virtual line from the configuration server of the second network according to the identifier of the virtual line Configuration information, where the configuration information is used to create the virtual AN; the access device creates the virtual AN according to the configuration information.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and equipment for establishing a virtual access node in an optical access network. Background technique [0002] figure 1 It is a schematic diagram of a scene of an optical access network (Optical Access Network, OAN for short). The OAN includes: Customer Premises Network (CPN for short), Access Network (Access Network) and Service Node Function (Service Node Function). The access network includes: Optical Line Termination (OLT for short), Optical Distribution Network (ODN for short), Optical Network Unit (ONU for short) / Optical Network Terminal (ONT for short) ) and Access Function (AF for short). The AF mainly provides mutual conversion between an ONU / ONT interface and a user network interface (UserNetworks Interface, UNI for short). If AF is built into the ONU, then figure 1 The access network in may omit the reference point identified with (a). If the AF ...

Problems solved by technology

[0004] At present, if an infrastructure operator (Infrustracture Provider, InP for short) opens up its access network and wholesales the access network to a Virtual Network Operator (VNO for short), the physical access nodes in the InP access network (Access Node, referred to as AN) cannot meet the service requirements of user equipment in the VNO network
