Embodiment 1

[0056] This embodiment provides a service implementation method. This embodiment combines the above embodiments and preferred implementation modes therein. The method includes the following steps:

[0057] Step 1: Configure the logical UNI interface on the OLT side, and configure the service type: E-LINE, E-LAN, E-TREE.

[0058] Step 2: Establish a mapping relationship between the logical UNI interface of the OLT and the service bearer channel between the OLT / ONU.

[0059] Step 3: The ONU establishes a mapping relationship between the user-side UNI interface and the logical UNI interface of the OLT.

[0060] Preferably, the above-mentioned logical UNI interface can use a VLAN or a MAC address as an identifier. A logical UNI interface can include one VLAN or MAC address, or multiple VLANs or multiple MAC addresses.

[0061] Preferably, the service bearer channel between OLT / ONU includes: GEM PORT of GPON technology, LLID of EPON technology, or VLAN+LLID, VLAN+GEMPORT.

Embodiment 2

[0079] This embodiment provides a method for implementing a service. This embodiment combines the above embodiments and preferred implementation modes therein. Figure 7 It is ELINE according to the embodiment of the present invention: EPL service realization mapping diagram (per EVC per SF multiple LLID), such as Figure 7 As shown, the present embodiment describes the EPL (Ethernet Private Line) service, realizes UNI1 to UNI2 port-level point-to-point (P2P, Point-to-Point) service transmission, and the method includes the following steps:

[0080] Step 1: Create a virtual connection VC between UNI1 and the logical UNI port on the OLT side, identified as VC1, and the IDs of the UNI ports on both sides of VC1 are the port ID of UNI1 and native vlan1 respectively. VC1 is a P2P type.

[0081] Step 2: Configure the intermediate association attribute of VC1 as tls vlan1, and for EPON, share the link LLID1.

[0082] Step 3: Configure a virtual private line instance (vII1) on the ...

Embodiment 3

[0097] This embodiment provides a method for implementing a service. This embodiment combines the above embodiments and preferred implementation modes therein. Figure 8 It is ELINE according to the embodiment of the present invention: EVPL service realization map (per EVC per SF multiple LLID), such as Figure 8 As shown, the present embodiment describes the EVPL (Ethernet Virtual Private Line) service, realizes P2P service transmission from vlan1 on UNI1 to UNI3 and P2P service transmission from vlan2 to UNI4 on UNI1, the method includes the following steps:

[0098] Step 1: Create two VC connections between UNI1 on the ONU and the logical UNI port on the OLT side, VC1 and VC2 respectively. The two UNI port identifiers of VC1 are respectively vlan1 and native vlan1, and the two UNI port identifiers of VC2 are respectively vlan2 and native vlan2. VC1 and VC2 are P2P types.

[0099] Step 2: Configure the intermediate association attributes of VC1 and VC2 as pon vlan1 and pon...

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 ...
