Technical field
The present invention relates to EPON (PON, Passive Optical Networks) in the system to the technology of user side equipment telemanagement, relate in particular to a kind of in the PON system, to the method for Optical Network Terminal (ONT)/these two kinds of user side equipment telemanagement of optical network unit (ONU).
Background technology
Along with the progress of society, also in progress constantly, means of communication is more and more abundanter for mechanics of communication, supports the equipment of these means of communications also constantly increasing.All can relate to the problem of management to all devices.
At present, in the system based on digital subscriber line (xDSL), the management method that this user side equipment administrative institute of modulator-demodulator (MODEM) is adopted is: manage by WEB (browser) management/TELENT (telnet) management or SNMP (Simple Network Management Protocol) way to manage etc.And, above-mentioned way to manage both can adopt the outband management mode, promptly realize Network Management by special network management path, network management data and business datum are separated, for network management data is set up the autonomous channel, for example can realize management from the direct login system of the user side interface of user side equipment to it; Can adopt the in-band management mode again, be about to management information and transmit in identical passage with business information, the user side equipment for the needs management must have an IP address, thereby realizes telemanagement.
Development along with mechanics of communication, in order to improve the transmission rate of data, introduced the PON technology, comprised Ethernet passive optical network (EPON) system, gigabit passive optical network (GPON) system based on the PON system of PON technology, and Wave division multiplexing passive optical network (WPON) system.Network element device in any PON (xPON) system all comprises the optical line terminal (OLT) of innings side and the ONU/ONT of user side.And, in the xPON system, both can adopt above-mentioned existing management method to manage to the management of its user side equipment, also can adopt new management method to manage.
Wherein, at new management method, such as in the EPON system, the management method that these two kinds of user side equipment management are adopted usually to ONT/ONU is: earlier each object that need manage is all defined a type branch (Branch)/leaf node (Leaf); Then, will be encapsulated into according to the management object that this definition sets in oam (OAM, Operations, the Administration and Maintenance) frame, send to ONT/ONU; At last, ONT/ONU resolves each Branch/Leaf, obtains management object.And in the GPON system, be managed entity (ME according to definition, ManagedEntity) management object is set, and manages by Optical Network Termination Management and Control Interface (OMCI, ONTManagement and Control Interface) frame transfer management object; Be different from the EPON system, according to the Branch/Leaf that defines management object be set, and manage by OAM frame transfer management object.
Existing management method of contrast and new management method if in the PON system, adopt existing management method, and inherit the way to manage in the existing management method as can be known, then must save R﹠D costs.But, adopt existing management method leading subscriber side apparatus, such as each ONU is managed, need be each different IP address of ONU distribution, so, when ONU quantity is huge, need a lot of IP address, cause nervous originally IP address resource nervous more.
If in the PON system, adopt new management method, then for existing all objects that need manage, all need to reset a whole set of management object according to the Branch/Leaf or the ME of definition, and the quantity of these management objects may be very huge, and what have just translates existing management object simply, cause the unnecessary duplication of labour, improved R﹠D costs.In addition, the management object of resetting also needs to carry out standardization, and still, standardized process is not only very long but also complicated.
In sum, the shortcoming that prior art exists is: owing in the existing standard, also be not the management object in the PON standard with the cura generalis object definition, therefore, in the PON system, need redefine management object, can't utilize the object of existing standardization to bring managerial inconvenience.
