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: GEMPORT 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 ELINE according to the embodiment of the present invention: EPL service realization map (perEVCperSFmultipleLLID), such as Figure 7 As shown, the present embodiment has described EPL (EthernetPrivateLine) service, realizes UNI1 to UNI2 port level point-to-point (P2P, Point-to-Point) service transmission, and this method comprises 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 nativevlan1 respectively. VC1 is a P2P type.

[0081] Step 2: Configure the intermediate association attribute of VC1 as tlsvlan1, for EPON, share the link LLID1.

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

[0083] Step 4: Config...

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 ELINE according to the embodiment of the present invention: EVPL service realization map (perEVCperSFmultipleLLID), such as Figure 8 As shown, the present embodiment describes the EVPL (EthernetVirtualPrivateLine) 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 vlan1 and nativevlan1 respectively, and the two UNI port identifiers of VC2 are vlan2 and nativevlan2 respectively. VC1 and VC2 are P2P types.

[0099] Step 2: Configure the intermediate association attributes of VC1 and VC2 as ponvlan1 and ponvlan2 respectivel...

Abstract

Disclosed in the present invention are a method and a system for service forwarding. The method comprises: ONU maps received service to the PON logical channel by Ethernet ID and / or UNI port ID of ONU user network interface, wherein the PON logical channel is a logical channel connecting the ONU and its corresponding OLT; OLT establishes mapping relations between the PON logical channel and MPLS instance through the logical UNI port thereon; and OLT forwards the service mapped onto the PON logical channel through the MPLS instance. By implementing the present invention, reduction in ONU complexity and cost can be 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 Ethernet-based line services (EthernetLineService, referred to as E-Line), Ethernet-based local area network services (EthernetLANService, referred to as E-LAN), Ethernet-based There are three types of Ethernet services (Ethernet Tree Service, E-Tree for short) to support end-to-end services. E-line, E-LAN, and E-TREE services are established on the basis of UserNetworkInterface (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, it can be an Ethernet interface or a logical port of the Ethernet int...
