Abstract

The invention discloses a service forwarding method and a service forwarding system. The service forwarding method comprises the following steps that: an optical network unit (ONU) maps the received service to a logical channel of a passive optical network (PON) through an Ethernet identifier and / or a port identifier of a user network interface (UNI) of the ONU, wherein the logical channel of the PON is a logical channel for connecting the ONU and a corresponding optical line terminal (OLT); the OLT establishes a mapping relationship between the logical channel of the PON and a multiple protocol label switching (MPLS) instance through the logical UNI port; and the OLT forwards the service mapped to the logical channel of the PON through the MPLS instance. By the method, the effect of reducing the complexity of the ONU and the cost is achieved.

Description

technical field

[0001] The present invention relates to the communication field, in particular, to a service forwarding method and system. Background technique

[0002] The Metro Ethernet Forum (MEF for short) defines the Ethernet-based line service (Ethernet Line Service, referred to as E-Line), the Ethernet-based local area network service (Ethernet LAN Service, referred to as E-LAN) ), Ethernet-based tree service (EthernetTree Service, referred to as E-Tree) three types of Ethernet services to support end-to-end services. E-line, E-LAN, and E-TREE services are established based on the User Network Interface (UNI for short), and each interface corresponds to a corresponding physical port or a logical port of a physical port. (Passive Optical Network, referred to as PON) system to achieve these business models demand is increasing, for the PON system, the UNI interface is the physical port of the ONU connected to the user, can be an Ethernet interface or a logical port of ...
