Thereby, the method is adopted, the data on the optical network unit or the optical network terminal can be operated, managed and maintained only after authorization of the optical line terminal, thereby lawful management operations can be allowed, and the safety of the operations can be guaranteed.
Description
Technical field
The present invention relates to a kind of to EPON (Passive Optical Network, PON) optical network unit in (optical network unit, ONU)/(opticalnetwork terminal ONT) carries out the method for safety management to Optical Network Terminal.
Background technology
Much be provided with current, for example, DSL (Digital Subscriber Line, Digital Subscriber Line) terminal equipment, various home gateways, wireless router, and the terminal equipment of PON or the like, nearly all support directly to log on the configuration management of carrying out data the equipment etc. from this locality.
A because common OLT (Optical Line Terminal in the PON system, optical line terminal) by optical distribution network (ODN, Optical Distribution Network) connects a plurality of ONT/ONU, 1:32 is generally arranged, 1:64 or 1:128 etc., it is a kind of natural broadcasting tree, each ONT/ONU of data that issues from OLT all can receive, only in the PON system, pass through to distribute different GEM (G-PON Encapsulation Method to each ONT/ONU, the GPON method for packing) PORT ID modes such as (GEM port-marks), the GEM PORT ID that ONT/ONU distributes according to OLT waits and distinguishes whether the data flow that issues is one's own, if oneself then accept this data, if not then abandoning of oneself.If certain ONT/ONU realizes that not according to the handling process of standard code perhaps it creates not one's own GEM PORTID in this locality, can accept not to be one's own data like this.For upstream data, be to authorize for each ONT/ONU by OLT, ONT/ONU just allows to send data at the time slot of its mandate then, if certain ONT/ONU sends data not according to the mandate of OLT, then can cause the upstream data conflict, and influence is normally used.
In addition, in the PON system, ONT/ONU is passive response fully, is in the status of subordinate, and all configuration datas etc. all should be that OLT issues; And OLT is the status that has the initiative, and initiates all configuration datas.
Therefore, if at any time, can log on ONT/ONU equipment from ONT/ONU this locality gets on, operation ONT/ONU is provided with, then being configured to data on the ONT/ONU etc. is modified probably, fail safe to the data of whole PON system etc. has very big threat, even can cause whole PON system paralysis to occur.
Summary of the invention
In view of the problems referred to above of the prior art, the present invention proposes the scheme of a kind of control and managing network unit/optical network terminal, be used for the simple and practical safety management that realizes the network unit/optical network terminal of EPON feasiblely.
The invention provides a kind of method of controlling the network unit/optical network terminal management, may further comprise the steps: step 1, after network unit/optical network terminal succeeded in registration, optical line terminal obtained the managing control information of network unit/optical network terminal; And step 2, described optical line terminal is described network unit/optical network terminal configuration management authority information, and sends to described network unit/optical network terminal, thereby revises the administration authority of described network unit/optical network terminal.
The method according to this invention also comprised the described managing control information of configuration on network unit/optical network terminal in the following manner: load or the unloading administration module before described step 1; Or adopt the variable mode to control.
Wherein, managing control information comprises: represent in the band that described network unit/optical network terminal supports and/or the information of outband management mode; Whether expression allows described network unit/optical network terminal to open in its band and/or the information of outband management mode; The upper united mouth that the expression network unit/optical network terminal is supported and/or with the information of registered permanent residence way to manage; Whether expression allows network unit/optical network terminal to open its upper united mouth and/or with the information of registered permanent residence way to manage; The information of representing the concrete way to manage that described network unit/optical network terminal is supported; Whether expression allows described network unit/optical network terminal to open the information of its concrete way to manage; Represent the username and password under the described concrete way to manage.
Wherein, concrete way to manage comprises: local serial ports lands that connections, telnet connect, browser interface lands connection, oam OAM channel management mode, Optical Network Termination Management and Control Interface (OMCI) protocol mode in the gigabit passive optical network (GPON), physical layer operations management maintenance (Physical Layer OAM, PLOAM) message mode or self-defined management agreement mode in the Simple Network Management Protocol connection, Ethernet passive optical network (EPON).
The mode that the method according to this invention, optical line terminal are obtained managing control information comprises: upload or directly inquiry.
Can adopt branch/leaf (Branch/Leaf) mode in the EPON system, (Managed Entity, ME) mode realizes can to adopt managed entity in the GPON system.In the EPON system, can adopt and carry out PLOAM inquiry/setting, in the GPON system, can adopt by OMCI passage or PLOAM message and inquire about/be provided with by the OAM passage.

Action comprises:
Obtain (GET): obtain one or more attributes;
Be provided with (SET): one or more attributes are set.
Notice comprises:
The property value change: this notice is used for the automatic updating record of managed entity management controlled attribute.Notice should be able to recognition property and new value thereof.AVC (property value change) tabulation of managed entity management control sees Table 1.
The AVC tabulation of table 1 management control
| Numbering | The property value change | Describe |
| 1 | Way to manage | Report the way to manage of current support |
