Description

A kind of method that realizes ADSL CPE telemanagement by SNMP

Technical field

The present invention relates to the method for network remote management, be specifically related to a kind of method that in access net system, realizes ADSL (Asymmetric Digital Subscriber Line) adsl communication treatment facility CPE telemanagement by the SNMP mode.

Background technology

In recent years, Chinese broadband access market steps into fast-developing track, and in all broadband users, ADSL user rises gradually, and the ADSL access way becomes the absolute main flow mode of broadband access.But the userbase of DSL broadband access network constantly enlarges, the operation of DSL network, the also corresponding increase of the workload of maintenance and management.In the flow process that at present broadband services of operator is opened an account, the user terminal configuration, the overwhelming majority of the work that accounted for is installed in the user family; When customer service fault or terminal configuration were revised by user error, the staff of operator must arrive and carry out fault location and recovery in the user family.Current, how to realize DSL professional dispose fast, user's fault is located compactly fast and problems such as solution, user terminal data configuration, software upgrading, has become the vital problem that the restriction broadband access market continues fast development.According to statistics, present most of DSL fault all occurs in user side, and this makes that the operation cost in broadband is high.In order to improve user satisfaction, reduce O﹠M cost, provide technical guarantee, realize the sustainable development of DSL broadband access for carrying out broadband services smoothly, be necessary to realize long-range centralized management, thereby reach the runing of DSL network whole process, manageable purpose DSL CPE terminal.

And the management of the CPE that present operator provides mainly contains three kinds of modes: 1, CPE is managed for configuration to CPE by TELNET; 2, by snmp protocol (Simple Network Management Protocol, Simple Network ManagementProtocol), at remote side administration network C PE.3, directly sign in on the CPE by the WEB page and be managed for configuration.This several method all can only manage CPE under the IP that clearly knows present CPE and disposed is and so on situation, otherwise cannot dispose; In addition for can only be point-to-point to the CPE direct control CPE one by one being configured respectively.But each must be furnished with public network IP address by the modem of pipe these three kinds of way to manages, and administrative staff must know that each is managed the public network IP of long-range CPE, because the IP address resource more and more lacks at present, require must the distributing IP address to become the mortal wound of this way to manage, particularly in telecommunication public network, because CPE quantity is very big, administrative staff cannot remember so many CPE IP addresses at all.

Our equipment provides two kinds of way to manages at present: 1, by the serial ports equipment that is directly connected to equipment is managed for configuration; 2, by snmp protocol (Simple Network Management Protocol, Simple Network Management Protocol) or use TELENET agreement (Telnet), at the remote side administration network equipment.For two kinds of way to manages of equipment, major advantage is that management means is relatively simple, does not need additional other equipment, and (personal computer PersonalComputer) just can be finished all configuration efforts only to need 1 PC.And, do not need to dispose corresponding managing I P (procotol, Intranet Protocol) address during therefore for configure network devices owing to directly connect managed device by serial ports, saved the IP resource.The problem that exists is that this dual mode all manages the local side information of equipment only, and just can not manage for remote subscriber CPE information.

Chinese invention patent ZL200217 has announced a kind of " based on the network device management method of ethernet technology ".Although this scheme provides a kind of new network device management method.Many the network equipments as a cluster unified management, except command facility, other managed devices are externally transparent, whole cluster only takies single publicly-owned IP address resource, but it can only use a plurality of managed devices a unified IP to manage, but it and equipment user's managing I P is layering, and promptly it can't manage by this unified IP terminal use ADSL CPE.Be its technology at equipment itself, do not manage the information of the long-range ADSL CPE of user side.Can carry out the remote centralized management to CPE by the equipment webmaster and just solve this problem.Promptly network equipment local side and remote subscriber can be carried out unified management by means of the publicly-owned IP that gives devices allocation.

Summary of the invention

The objective of the invention is deficiency and defective, provide a kind of new Simple Network Management Protocol SNMP that passes through to realize method that ADSL (Asymmetric Digital Subscriber Line) adsl communication treatment facility CPE is carried out telemanagement at above-mentioned conventional network equipment Managed Solution.

This method may further comprise the steps: management station to it is assigned with the order of active user's information and the current operation of carrying out in the interface, and wherein active user's information comprises slot number and port numbers; The long-distance user of the current needs management of clicking according to the interface, obtain its slot number and port numbers, obtain the current community's name of current graphic network manager, account for two bytes by slot number respectively, the order of port numbers two bytes is formed the string of one 4 byte, to go here and there suffix as community's name of being obtained then, by the community of pipe CPE, be put in community's field of current SNMP message as current; Agent receives the request message from management station, earlier according to the source IP address that receives, judge and determine that this message is from ply-yarn drill or management station, be defined as from management station, with regard to analytic message, obtain the field S1 of community according to current message characteristic, slave unit obtains the S2 of community of current managed device Agent, judges whether the suffix of back 4 bytes of the current message that receives is numeral and the limited field that satisfies equipment slots item and port numbers; And community's content of removing outside these 4 bytes is kept at S3, if S2=S3, so just preceding two bytes of 4 byte suffix of this message are taken out, and obtain the IP of corresponding ply-yarn drill, obtain with current that message is intact issues corresponding ply-yarn drill by these two fields; Ply-yarn drill receives the request command from the SNMP CPE management of core dish, after definite current message is legal, latter two field in the 4 byte suffix of the community of this message is taken out, locate the CPE of current management and preserve corresponding information by this two field information, then back 4 bytes of this message community field are removed, again group is wrapped, and will be somebody's turn to do the CPE that the new message of forming is sent to current management; CPE receives the request message from ply-yarn drill, judges the legitimacy of current message, carries out normal response and handles.

When ply-yarn drill receives message from CPE, according to the station location marker port numbers of modulator-demodulator on this ply-yarn drill, and this station location marker slot number on equipment of ply-yarn drill, this two information is pressed slot number 2 bytes, port numbers 2 bytes are formed the string of one 4 byte, take out the community of the current message that receives then, this 4 byte serial is added to the back of community as suffix, replace community in the message that receives with new community then, form new message, and be sent to the core swapdisk; The core swapdisk receives the message from ply-yarn drill, if this message is a response message, then directly is sent to the management station of its request, if the warning message that CPE initiatively reports, then directly is sent to the management station of the receiving alarm message of equipment disposition; Management station receives the message from the core swapdisk, and its back 4 byte suffix according to the community of this message obtain the positional information of the current CPE that will manage, then corresponding positional information slot number and card number and corresponding management information is sent to the interface; The interface receives the message from management station, determines to be shown to user's content according to response contents; If just carrying out corresponding warning information, handles warning message.

This scheme is all remote subscribers of many network equipments, and with respect to managed devices, all users are externally transparent, whole management system except the IP of managed device be disclosed, the remote subscriber public network IP all is sightless for the user.

Advantage of the present invention is: the mode that adopts two-stage to transmit does not need to preserve any message content, does not need the organize content of message is carried out any processing yet, both can save the space, can save time yet.This method is simple, and directly, workload is little, does not need what expense substantially, and cost is low.The most important advantage of another one is that this management method is not wanted the public network IP that the manager knows long-distance user CPE, and promptly user's public network IP is opaque for the manager, does not need to know.

In addition, adopt long-range ADSL CPE Managed Solution, for the keeper, its operation does not have any difference with mode of operation of other webmaster order, therefore uses very easyly, need not expend time in and grasp and be familiar with how new instruction.

Embodiment

Describedly a kind ofly realize the method for ADSL CPE telemanagement by SNMP, its control procedure of utilizing community's name in the snmp protocol to identify and discern ADSL CPE comprises:

The process of interface request downward message:

The order of management CPE is assigned at the interface according to user's request: management station to it is assigned with the order of active user's information (slot number and port numbers) and the current operation of carrying out in the interface.

Manager sends the module of get/set/get-next/get-bulk message: the long-distance user of the current needs management of clicking according to the interface, obtain the position (slot number) and the position (port numbers) of this port on this card of the card at its place, obtain the current community's name of current graphic network manager, according to agreement, account for two bytes by slot number respectively, the order of port numbers two bytes is formed the string of one or four bytes, to go here and there suffix as community's name of being obtained then,, be put in community's field of current SNMP message by the community of pipe CPE as current.

The core swapdisk receives and the module of the get/set/get-next/get-bulk message that processing management station sends: Agent receives the request message from management station, according to the source IP address that receives, judge and determine that this message is from ply-yarn drill (now block the IP address feature is arranged) or management station earlier.Be defined as from management station, with regard to analytic message (if processing being arranged below then) from ply-yarn drill.Obtain the field S1 of community according to current message characteristic, slave unit obtains the S2 of community of current managed device Agent, judges whether the suffix of back 4 bytes of the current message that receives is numeral and the limited field that satisfies equipment slots item and port numbers; And remove the community's content outside these 4 bytes] be kept at S3, if S2=S3, so just preceding two bytes of 4 byte suffix of this message are taken out, and obtain the IP of corresponding ply-yarn drill, obtain with current that message is intact issues corresponding ply-yarn drill by these two fields.

Ply-yarn drill receives the module from the message of core swapdisk: ply-yarn drill receives the request command from the SNMP CPE management of core dish, after definite current message is legal, latter two field in the 4 byte suffix of the community of this message is taken out, locate the CPE of current management and preserve corresponding information by this two field information, then back 4 bytes of this message community field are removed, again group is wrapped, and will be somebody's turn to do the CPE that the new message of forming is sent to current management.

CPE receiver module: CPE receives the request message from ply-yarn drill, judges the legitimacy of current message, carries out normal response and handles.

The up handling process of CPE message:

Ply-yarn drill receives the module of handling from the message of CPE: when ply-yarn drill receives message from CPE, according to the station location marker port numbers of modem on this ply-yarn drill, and this station location marker slot number on equipment of ply-yarn drill, this two information is pressed slot number 2 bytes, port numbers 2 bytes are formed the string of one 4 byte, take out the community of the current message that receives then, this 4 byte serial is added to the back of community as suffix, replace community in the message that receives with new community then, form new message, and be sent to the core swapdisk.

The core swapdisk receives the processing module from the message of ply-yarn drill: the core swapdisk receives the message from ply-yarn drill (source IP address according to message is judged), if this message is a response message, then directly be sent to the management station of its request, if warning message, then directly be sent to the management station of the receiving alarm message of equipment disposition.

Management station receives the processing module from the message of core swapdisk: management station receives the message from the core swapdisk, its back 4 byte suffix according to the community of this message obtain the positional information of the current CPE that will manage, then corresponding positional information slot number and card number and corresponding management information are sent to the interface.

The interface receives the processing module from management station's message: the interface receives the message from management station, determines to be shown to user's content according to response contents; If just carrying out corresponding warning information, handles warning message.

Described a kind of method by SNMP realization ADSL CPE telemanagement, its message all is the way to manage of accepted standard SNMP message, just its identification is by means of community in the SNMP message managed object to be carried out flexible positioning.

Described a kind of method that realizes ADSL CPE telemanagement by SNMP, be used for realizing that the mode of its management is to transmit the purpose that reaches management by two-stage, core swapdisk and ply-yarn drill are when transmitting, do not need to preserve current information of managing, more do not need the organize content of message is handled, just core swapdisk and ply-yarn drill are used as two passages and manage.It has reached by a public IP address manages simultaneously to local side apparatus and remote subscriber.

Advantage of the present invention is: the mode that adopts two-stage to transmit does not need to preserve any message content, does not need the organize content of message is carried out any processing yet, both can save the space, can save time yet.This method is simple, and directly, workload is little, does not need what expense substantially, and cost is low.The most important advantage of another one is that this management method is not managed the public network IP of knowing long-distance user modem, and user's public network IP is opaque for the manager, does not need to know.

For example need manage No. 12 CPE on No. 3 groove positions now, community's conversion process is as follows:

The interface assign that the CPE to No. 3 groove position 12 ports manages order (this moment, community was the adsl of community of management station's configuration)---management station receives the order that CPE is managed, slot number (2 byte) will be added after the community, port numbers (2 byte) information, the group bag is sent to core swapdisk (community in the message is adsl0312 at this moment)---the groove position information 03 in the community of the message that core swapdisk basis obtains then, know that the current CPE that will manage is No. 3 ports on the groove position, just corresponding message is remained untouched and issue that No. 3 groove positions (community in this moment message still is adsl0312)---ply-yarn drill receives the request message from the core swapdisk, the port information 12 by pipe CPE is wherein taken out, and the suffix 0312 of the community in the message removed, again group bag sends to that No. 12 CPE (community in this moment message is adsl)---CPE receives correct solicited message, carry out the respective request message response (this moment, the community in the response message was adsl)---ply-yarn drill is received corresponding response message, take out the community of this message, in the locating information port numbers of locating information slot number that adds self equipment of living in thereafter and the CPE that received back to community, again group bag and message sent to core swapdisk (this moment, the community of message was adsl0312)---the core swapdisk receives the response message from ply-yarn drill, the IP address of the management station of the request of the request message of the correspondence of this response message is taken out, this response message is issued corresponding management station (community in the message is adsl0312 at this moment)---management station's modification response message, relevant response information is passed to the interface, for demonstration.The technical problem that solves during ADSL CPE management design comprises: whole system, comprise local side and far-end, and only need a public network IP to manage; All long-range ADSL CPE information all are transparent for the keeper; SNMP message by standard manages; Can satisfy the demand to ADSL CPE of operator; The demand of the ADSL CPE that increases newly for operator, equipment does not need to increase any content, just can satisfy.
