Description
Technical field
The present invention relates to point-to-multipoint smooth access technology field, relate in particular to the method, apparatus and system that realize a kind of point-to-multi-point system trunking management in EPON.
Background technology
PON due to low cost, safeguard simply, and technology reaches its maturity and becomes one of mainstream technology of optical access network.Existing PON comprises broadband passive optical network (Broad Passive Optical Network, BPON), gigabit passive optical network (Gigabit Passive Optical Network, GPON), and ethernet passive optical network (Ethernet Passive Optical Network, EPON).Referring to Fig. 1, structural representation for the PON network architecture, PON is by optical line terminal (Optical Line Terminals, OLT), optical distribution network (Optical Distribution Network, ODN) and a plurality of optical network unit (Optical Network Unit, ONU) three parts form.OLT is for central office, and ONU is positioned at subscriber household, roadside or building.Trunk optical fiber between OLT and ONU, optical branching device and branch optical fiber are referred to as ODN.Direction from OLT to ONU is called down direction, and the direction from ONU to OLT is called up direction.
Up direction adopts the mode of time division multiple access (Time Division Multiple Address, TDMA) access, and each ONU only sends the data of oneself at the time slot of OLT appointment.Down direction adopts time division multiplexing (Telemetric Data Monitor, TDM) mode of broadcast sends data to each ONU, the optical branching device place of optical signal power in ODN that is loaded with all ONU total datas is divided into some parts, arrive each ONU through each branch optical fiber, each ONU collects one's own downlink data according to corresponding sign.
In existing PON system, the radius that OLT covers ONU is no more than 20km, and the ONU negligible amounts that OLT docks by optical branching device causes in traditional PON network architecture OLT quantity more.And the OLT band of position is remote, disperse, very inconvenient to the administering and maintaining of OLT, cause plant investment and maintenance cost higher.In order to simplify the PON network architecture, reduce plant investment and maintenance cost, produce PON and zoomed out (Long reach PON, LR-PON) technology, this technology is to zoom out the radius that OLT covers ONU, to reduce the quantity of OLT.Increased the PON system construction drawing of Extender Box as shown in Figure 2, this PON system in the industry cycle is known as long distance P ON (Long Reach PON).In Long ReachPON, Extender Box is EB ANI interface near the interface of OLT side, and Extender Box is the EB uni interface near the interface of optical splitter side.Distance between OLT and Extender Box can reach 40Km, and the distance between Extender Box and ONU can reach 20km, and after introducing Extender Box, the coverage of Long Reach PON can reach 60Km.
Wherein Extender Box mainly realizes the enlarging function of uplink and downlink signals, it has multiple different implementation methods, a kind of is with the form of light signal, to send after upper and lower provisional capital is converted to light signal the signal of telecommunication and carries out shaping again, i.e. OEO mode (as shown in Figure 3); Another kind is that the employing of upper and lower provisional capital is directly amplified rear transmission to light signal, i.e. OA mode (as shown in Figure 4).In addition, also have the mixing application of these two kinds of modes, as descending employing OEO mode, and up employing OA mode (as shown in Figure 5); Or descending employing OA mode, and (as shown in Figure 6) such as up employing OEO modes.
For the management of Extender Box, industry proposition at present is a kind of to be managed Extender Box as stand-alone network elements, and the agreement adopted is Simple Network Management Protocol (Simple NetworkManagement Protocol, SNMP).Due in existing PON system, snmp protocol is the agreement that network management system is supported, be mainly used between network management system and managed device, between OLT and ONU, usually do not adopt snmp protocol to manage, but realize the management of ONU by the terminal management agreement as optical network terminal management and control interface (ONT Management and Control Interface, the OMCI) agreement of GPON standard.Like this, manage Extender Box if adopt snmp protocol in the PON system, user's side of OLT adopts two kinds of management agreements simultaneously, increased the difficulty of network design, during simultaneously due to the employing snmp protocol, can only directly to Extender Box, be managed by network management system, OLT is out of hand to Extender Box.

Owing between the EB ANI interface module of each Extender Box and EB uni interface module, having one-to-one relationship, so, for the managed entity EB ANI ME that manages EB ANI interface module with between the managed entity EB UNI ME that manages EB uni interface module, also setting up one-to-one relationship, specifically can carry out association by explicit or implicit.Wherein, explicit association is associated EB UNI ME entity pointer attribute to be set in EB ANI interface module managed entity EB ANI ME or associated EB UNI ME entity pointer attribute is set in EB uni interface module managed entity EB UNI ME, when setting up between EB ANI ME and EB UNI ME incidence relation, associated EB UNIME example ID is inserted in the EB UNI ME entity pointer attribute of the association in corresponding EB ANI ME, or associated EB ANI ME example ID is inserted in the EB ANI ME entity pointer attribute of the association in corresponding EB UNI ME, the implicit expression association is to adopt identical sign by the example of the EB ANI ME that will be mutually related and the example of EBANI ME.
Due to every couple of EB ANI, EB uni interface module is positioned at same circuit board (Circuit pack) upper (as shown in Figure 7), also can lay respectively at two different circuit boards (Circuit pack) upper (as shown in Figure 8), so need equally to set up for managing each EB ANI, the EBANI ME of EB uni interface module, EB UNI ME and incidence relation for the Circuit Pack ME (this ME quotes G984.4) that manages each circuit board, when EB ANI and EB uni interface module were positioned at same circuit board (Circuit Pack) when upper, because EB ANI ME and EB UNI ME have set up incidence relation, the Circuit Pack ME that only in EB ANI ME and EB UNI ME need be associated with to the circuit board (Circuit Pack) for managing its place gets final product (as shown in Figure 9), when EB ANI and EB uni interface module were positioned at various boards (Circuit Pack) when upper, need respectively EB ANI ME and EB UNI ME to be associated with respectively for managing the Circuit Pack ME (as shown in figure 10) of the circuit board at place (Circuit Pack) separately.Specifically can carry out association by explicit way or implicit.Wherein, explicit association concrete mode associated with implicit expression is same as described above.
Wherein, can be carried out the difference numbering by EB ANI interface module, the EB uni interface module of this Extender Box between different Extender Box is distinguished.
Like this, by administration module in trunking, for realizing ONU GTC and OMCI function, EB ANI ME and EB UNI ME that OLT just can be corresponding by each Extender Box manage trunking, and detailed process is as follows:
1, trunking automatically creates for managing Cardhold ME, the Circuit Pack ME of groove position, circuit board, and sets up their corresponding relation according to actual groove position, circuit board arrangement after starting;
2, trunking creates EB ANI ME example and the EBUNI ME example of EB ANI interface module and EB uni interface module for managing Extender Box automatically according to the Extender Box of actual disposition after starting, and sets up incidence relation between EB ANI ME example and EB UNI ME example and the incidence relation between EB ANI ME example, EB UNI ME example and place circuit board managed entity Circuit Pack ME example
