Description
Technical field
The present invention relates to the networking technology of communication equipment, relate in particular to the method that in communication network, detects many frames equipment connection mode.
Background technology
Along with popularizing of telecommunication service, the surge of number of users is had higher requirement to communication equipment.But the communication equipment that only has high reliability, big capacity, plurality of specifications smooth expansion just more has the market competitiveness.
Fig. 1 shows a kind of schematic diagram of many frames equipment connectivity scenario.As shown in Figure 1, it adopts a main frame to connect some modes from frame, can be according to capacity needs flexible configuration from the quantity of frame.
Main frame is with two classes are professional to be connected from having between the frame.One class is a messaging service, is used for mutual control messages, running status, heartbeat etc. between each frame in the equipment; One class is a bearer service, is used to carry user's data stream.The former size of message is less relatively, and the reliability height of requirement uses the mode of packet switching to transmit usually, and is insensitive to line connection, can discern route automatically, as long as physical connection is arranged, message can arrive smoothly.Simultaneously there is the heartbeat testing mechanism to detect the reliability of connection again.So-called heartbeat detection mechanism is meant that in distributed system, main control module periodically sends query messages to each accessory module, and accessory module is responded a response message after receiving query messages immediately.If main control module do not receive replying of accessory module for a long time, then think accessory module or taken place to take the troubleshooting measure unusually to the communication link of accessory module.If accessory module is not received the query messages of main control module for a long time, also can think main frame module or unusual to the communication link of main control module, also can take corresponding troubleshooting.
For bearer service, be characterized in that size of message is big, real-time requires high, normally adopts Circuit-switched mode, and is strict to connected mode, needs to specify annexation.Main frame with adopt many high capacity communication circuits to be connected (as optical fiber) from bearer service between the frame, be the assurance reliability simultaneously, circuit adopts the mode of active and standby usefulness.
This device interior networking plan has satisfied the requirement of previously described high reliability to communication equipment, big capacity, plurality of specifications, smooth expansion preferably.But the configuration of connection line has no small difficulty in actual use with being connected between a large amount of frames.In beginning or network rebuilding process and since misconnection connection line cause the obstructed accident of bearer service to happen occasionally.
Common way is to plan in advance to be used on the circuit that bearer service connects between frame, the corresponding relation of port at present, and uses the configuration order input equipment on equipment.Be used on the connection line methods such as adhesive label, the mark line alignment.
The shortcoming that such scheme exists is:
1. need delete original configuration when changing net, carry out new configuration again;
2. the correctness of Lian Jieing only relies on the workmen to guarantee with manual method;
3. lack real-time detection means, can not provide alarm and enough locating information timely, be difficult to the guidance technology personnel and in time correct these mistakes situations such as incorrect link, leakage connection, virtual connections occurring.
Summary of the invention
For solving the problems referred to above of prior art, the purpose of this invention is to provide a kind of method that detects the connected mode of many frames equipment, by in the link layer data frame structure of service bearer circuit, inserting identification information, the equipment that makes can carry out detection and Identification to connection line between each frame in real time, and can and then judge the correctness and the availability of annexation.
For achieving the above object, the invention provides a kind of method that detects many frames equipment connection mode, described many frames equipment comprises that main frame connects veneer, main frame control board, with be connected veneer from frame, have at least one communication interface on each described connection veneer, described method comprises: 1) each communication interface sends to its butt joint communication interface with self information, and receives the information of its butt joint communication interface; 2) each described connection veneer handle sends to described main frame control board with its communication interface separately and the information of docking the join dependency of communication interface; 3) described main frame control board is judged described connection status between frame and main frame according to the information of being received.
Described method can further comprise the step that legal annexation is come into force.The described step that comes into force makes it to participate in service bearer for the connection available communication interfaces that will meet following condition comes into force by the automatic or manual mode: 1) configuration available and do not exist from the frame configuration connect the configuration from the frame of conflict or available connection conflict available and do not exist configuration to connect the veneer of conflict or available connection conflict and connect on the available veneer all connect available light mouths; 2) all that connect the available available veneer of connection from frame connect available light mouths.
Preferably, each communication interface sends to its butt joint communication interface with in the spare bits or extension bits in the link layer data frame structure of self-position and state information insertion service bearer circuit, and described butt joint communication interface reads corresponding information in Frame.
Preferably, the positional information of the communication interface of the interface channel of each veneer by messaging service butt joint that positional information, state information and each communication interface of each communication interface are received sends to described main frame control board.
Preferably, the positional information of the communication interface of the butt joint that each veneer is received positional information, state information and each communication interface of each communication interface of sending to described main frame control board (following the transmission of main frame control board is abbreviated veneer as " reporting ") goes to tremble processing.Go to tremble processing and can be keep preceding twice by detected each communication interface link information of veneer and the link information that reported last time, if this detected link information with last time detected link information identical but with to detect information last time different, and different with the link information that reported last time, then report this information.
The connection legitimacy judgement that described main frame control board carries out comprises the judgement of communication interface legitimacy, and veneer connects legitimacy to be judged, connects the legitimacy judgement from frame, and judgement is carried out with the angle of communication interface from the frame veneer.
Method of the present invention allows the user to specify all or part of annexation with configuration order, and the annexation of configuration is carried out verification with actual annexation.For wrong or disabled or provide corresponding alarm prompt, in time correct to instruct engineers and technicians with the situation that is connected that configuration is not inconsistent.For correct available connection, then informing business module bearer service.Workload when having reduced actual networking has improved the reliability that equipment connects, and eliminates network and connects hidden danger, has reduced wrong odds, has significantly improved orientation problem speed.

Embodiment
Below in conjunction with accompanying drawing, preferred implementation of the present invention is elaborated.
Fig. 2 is the main frame and the connection diagram that is connected from the frame bearer service of an embodiment of using many frames equipment of method of the present invention.Need explanation, which kind of enforcement of the present invention communicate by letter irrelevant with application with, essence of the present invention is the connection that is used for Business Stream between each module of high capacity communication device interior, all can use so long as be used for the link-layer frame structure of the high capacity communication circuit of device interior intermodule connection, corresponding frame structure can be expanded voluntarily.Which kind of business the present invention not limiting telecommunication equipment externally provides, and does not also relate to change and expansion to the frame structure in the telecommunication circuit that connects between the communication equipment.
For ease of explanation, give an example with optical fiber interface (hereinafter to be referred as the light mouth) in this specification, but as above illustrated, application of the present invention is not limited to the light mouth.Substantial principle of the present invention, design and the scheme that illustrates in the specific embodiment mode can correspondingly be applied to other high capacity communication interfaces hereinafter.
As shown in Figure 2, be useful on the pair of control plate of the mutual backup of Comprehensive Control in the main frame, a veneer A left side and the A right side with the main and standby relation each other that is used to be connected, a C left side and the C right side, (two active and standby each other veneers are inserted on the groove position adjacent in the equipment frame to be useful on board B connected and main and standby relation each other a left side and the B right side from frame equally, so distinguish with groove position, the left and right sides) many to communication interface (being the light mouth in the present embodiment), the quantity that connects optical fiber can increase and decrease according to the traffic carrying capacity needs.Because it is a plurality of from frame that main frame need connect, so it is many to connecting veneer, with number differentiation of different plates to peg graft.The frame number differentiation of professional frame.
Fig. 3 is the schematic flow diagram of method of many frames of detection equipment connection mode of one embodiment of the invention.As shown in Figure 3, in the preferred embodiment, the method of many frames of detection equipment connection mode of the present invention comprises that each light mouth sends to butt joint light mouth with self-position and state information and receives the information that the timing of information (step 301) that butt joint light mouth sends, link information detects and report (step 302), the arrangement of main frame control board to be received, the legitimacy (also can be described as availability) that forms connection relation information (step 303), annexation is judged (step 304) and made and is judged as the legal connection several steps such as (steps 305) that comes into force.
For realizing the present invention, each light mouth need possess recognition capability to the light mouth that docks with it.This can realize by inserting each light mouth positional information in spare bits in the frame structure of fiber-optic signal or the extension bits.
In step 301, behind single board starting, each the light mouth on the veneer with the frame at own place number, slot number, light slogan, active and standbyly insert in the spare bits of link layer data frame structure or the extension bits and send to the light mouth of its butt joint with position information such as states.This butt joint light mouth reads above-mentioned positional information from the Frame that receives.Should be appreciated that the present invention correspondingly will use the link-layer frame structure in these circuits when being applied to except that optical fiber communication other and being used for high capacity communication line traffic that the device interior intermodule connects.
In this case, the timing that can carry out link information detects and reports (step 302).After the normal operation of each veneer, each single board starting cycle timer regularly reads position, the state information of the butt joint light mouth that each light mouth receives, when changing, information judges whether to satisfy the condition that reports link information, after satisfying report condition, this light mouth positional information, state information whether (connect normally) and detected butt joint light mouth positional information are sent to main frame master board aggregation process by the interface channel of messaging service together.
For avoiding when optical fiber connects instability, frequently reporting link information, need to adopt and go to tremble processing.Specifically, can be set to just think effective link information when detecting identical information double.If detect an error message once in a while, can not report.After through two sense cycle, then this detected once in a while error message has just become the information that detected last last time, this information and above-mentioned latter two cycle detection to information be inconsistent.On the other hand, this latter two cycle detection to information might with that time mistake before detected consistent (just reporting last time), also may be inconsistent, this just need judge and reports.Concrete processing method is: the link information that each veneer keeps preceding twice detected light mouth link information and reported last time, if this detected link information and last time are detected identical but with to detect information last time different, and different with the link information that reported last time, then report this information.
The cycle of timer is set needs to consider two aspect factors:
1) in general in a single day the annexation of equipment determines the back with regard to tenacious of, and too frequent detection can cause the unnecessary wasting of resources and shake.
2) the oversize sensitivity that can reduce perception when annexation changed again of timer.Comprehensive two aspect factors are set to detection in per 5 seconds once in a preferred embodiment of the invention, go to tremble perception connection variation after 10 seconds, in the scope that can bear.
In step 303, the master board on the main frame uses two data forms in the internal memory to be preserved management when collecting the light mouth link information that veneer reports, and to main frame connection veneer be connected the information that veneer reports from frame and handle respectively.Because every optical fiber is unidirectional,, connect an optical fiber respectively so be divided into the Xiao Guangkou of reception (RX) and transmission (TX) both direction under each light mouth again.Owing to be two optical fiber,, but can not know directly that what join with local terminal transmission light mouth is the reception light mouth of which light mouth so each light mouth can only obtain receiving with local terminal the positional information of the transmission light mouth that the light mouth links to each other.Have only the reception light mouth of waiting until that light mouth to detect the positional information that local terminal inserts, and just know this information after being aggregated into master board.
For the link information that reports from frame, its detected opposite end light message breath is directly inserted the Rx position of following table correspondence according to its frame number, groove position, the left and right sides, light slogan:
Table one is from frame light mouth link information table
| From frame number | Groove position, left side veneer | | Rx (reporting) from frame |
| Tx (main frame reports) | |||
| Light mouth 2 | Rx | ||
| Tx | |||
| Light mouth 3 | Rx | ||
| Tx | |||
| Light mouth 4 | Rx | ||
| Tx | |||
| Right groove position veneer | | Rx | |
| Tx | |||
| Light mouth 2 | Rx | ||
| Tx | |||
| Light mouth 3 | Rx | ||
| Tx | |||
| Light mouth 4 | Rx | ||
| Tx | |||
| …… | …… | …… | …… |
The link information that main frame is reported (frame number, slot number, light slogan, the active and standby state of using) is managed with the form of table 1 and following table 2.The judgment processing of back mainly is based in the table 1 being that object carries out from frame, so connect the positional information that veneer receives for main frame, all will convert the link information that sends the light mouth from frame to and insert table 1.But only make the problem that has like this: when optical fiber connects change, same light mouth can report effective link information once more, when receiving the new information that reports, just need also need information is before deleted from table 1 like this except new information is inserted the table 1.Because table 1 to be index object from frame, if directly search and delete the link information that main frame once reported, can cause lower efficient.Therefore introducing table 2 is used for preserving the link information that main frame light mouth last time reported.
In table 2, with main frame connecting plate number is index, after receiving the information that reports, at first find the information that reports before the light mouth according to groove position, the left and right sides, light mouth, and relatively, if change, then remove the Tx information from frame light mouth correspondence position table 1 of butt joint with it of preserving before this, newer information is write table 2.Simultaneously the data from the corresponding Tx of frame light mouth position of new detected butt joint in the table 1 are changed into the positional information that this main frame connects optical interface.When Guang Kou reports fault, need in table 1, remove the positional information that writes before this.
Table 2 exchange frame light mouth receives information table

When the connection veneer breaks down,,, need to remove information corresponding in two tables to the light mouth on the failing single board for guaranteeing the validity of data in above two tables.
According to the present invention, in step 304, the legitimacy (or availability) of annexation is judged and can be finished by equipment manager, equipment manager utilizes the maintenance terminal that equipment provides, and (it links to each other with equipment by network or other modes, finish data configuration to equipment, status poll etc.) annexation to write down in the visual querying method question blank 1, thus the also connection situation of corrective manually checked.In addition, step 304 also can be finished by the automatic connection legitimacy determination methods that equipment utilization the following describes.
The judgement of light mouth annexation legitimacy is mainly carried out according to the data in the table 1.Whether legal connect available (promptly can bearer service) from the light mouth of frame preceding judging one, needs to guarantee the correctness of the annexation of existing configuration, preferably, at first configuration data carried out verification before legitimacy is judged.
According to one embodiment of present invention, the constraints of carrying out above-mentioned judgement can be: if there is the light mouth to have configuration, then configuration preference when the actual connected mode of optical fiber of this light mouth or other light mouths is conflicted therewith, all will be considered to fault.
Main when breaking down with optical fiber that connects or veneer when being used for, it is short more that business switches to the time of the optical fiber of standby connection or veneer, just more little to the influence of business.The master can hand on the standby connection veneer smoothly with the bearer service on the connecting plate when breaking down, the connection line that requires to form main and standby relation is the mirror image connection, both the light mouth on a certain connection veneer must be connected on the optical interface of respective side (being all left side or right side) of main frame from the frame, also must be connected on the veneer that forms main and standby relation on the main frame with the connecting plate of its formation main and standby relation, and link position is identical.Under the situation that bearing capacity meets the demands, a pair of connection veneer of main frame can connect a plurality of from frame.Light mouth from frame can only be connected on the active and standby each other a pair of main frame connecting plate.For example: the light mouth of B left side veneer can be connected on an A left side or the C left side veneer in the prior figures 2, can not be connected on the right veneer of the A right side or C; If it is upper left that a B left side is connected on A, it is upper right that the B right side also can only be connected on A so; If No. 1 light mouth of B left side veneer is connected on No. 2 light mouths in an A left side, No. 1 light mouth of the right veneer of B also must be connected on the right No. 2 light mouths of A so.
Under these conditions, according to the determination methods of connection legitimacy of the present invention can be according to light mouth, veneer, judge successively from small to large from the order of frame:
One, the light mouth is judged:
At first the light mouth is done inspection, and mark each light mouth connection status, the connection status of light mouth comprises:
A. connect unavailable
B. the light mouth receives unavailable
C. the light mouth sends unavailable
D. the light mouth is two-way unavailable
E. dispose unavailable
F. dispose available
G. connect available
Concrete deterministic process is as follows:
1-1) check whether receiving and sending messages of light mouth has a side not report or undesired.In this way, then judge the reception of light mouth, transmission or two-way unavailable, send alarm; Otherwise
Whether what 1-2) the light outlets correspondence was received in inspection is the same light mouth of same connection veneer on the main frame, whether is all left side or right side with this plate, if not then this light mouth connection is unavailable, sends alarm; Otherwise
Whether have configuration exist, have three kinds of situations this moment if 1-3) inquiring about this light mouth:
1-3-1) as if configuration and inconsistent with the information that detects (being that each light mouth of previously described each veneer receives and summarizing and reporting arrives the positional information that main frame is controlled the connected light mouth of veneer) is arranged, then the configuration of light mouth is unavailable, sends alarm;
1-3-2) the light mouth configuration is arranged and the annexation of the light mouth that is provided with the user identical, think that then this light mouth is available for configuration;
1-3-3) do not have configuration as the light mouth, then the light mouth connects available.In other words, getting rid of 1-1) and 1-2) after the both of these case, think that it is good that the light mouth connects.
Two, veneer is judged
According to light mouth check result, veneer is done inspection, and mark veneer connection status and conflict type,
The conflict type comprises:
A. there is not conflict
B. can use to connect conflict, refer to connect exist between the available light mouth and conflict (as not being connected on the same main frame subtending board), two available light mouths of connection all can not bearer service
C. configuration connects conflict, clash (as not being connected on the same main frame cascade veneer) between the light mouth (comprising the available and disabled light mouth of configuration of configuration) that refers to connect the available light mouth and have configuration, disposing available light mouth can bearer service, and connecting available light mouth can not the bearer service deterministic process:
2-1) if endlessly dispose the light mouth of annexation, and all connect available light mouth and are not connected on same main frame and connect on the veneer, think that then there is available connection conflict in this veneer, send alarm, change 2-5 over to)
2-2) if the light mouth that disposes annexation is arranged and is connected available light mouth, be not connected on the same veneer on the main frame but connect available light mouth and the light mouth that configuration is arranged, think that then this veneer exists the configuration connection to conflict, and sends alarm;
2-3) veneer thinks that then the veneer configuration is available if the available light mouth of configuration is arranged, otherwise
2-4) veneer has available connection light mouth if there is not configuration available light mouth, and does not have the conflict of connection, and then veneer is available for connecting, otherwise
It is unavailable 2-5) to judge that veneer connects.
In this manual, " dispose available light mouth " and refer to for all normal light mouth of transmitting-receiving, the user has specified the annexation of this light mouth on configuration interface, if this annexation and the equipment annexation of detected this light mouth automatically match, claim this light mouth to be the available light mouth of configuration.Otherwise promptly be called " disposing disabled light mouth "." dispose available veneer " and refer on this veneer and have " disposing available light mouth ".And " connecting available light mouth " refer to, when not specifying the annexation of this light mouth, Equipment Inspection to light mouth annexation normal." connecting available veneer " refers to, there is not configuration available light mouth (have configuration and can not use up mouth) in this veneer, connect available light mouth but exist, and connect the annexation of available light mouth and other light mouth or configuration relation (can not use up at configuration mouth says) and do not clash, then think to connect available veneer.Otherwise claim this veneer to have " available connection conflict " or " configuration connects conflict ", this veneer connects unavailable." configuration preference " principle that adopts when judging the connection legitimacy that preamble is mentioned is presented as: for the veneer that has configuration available light mouth (user has specified annexation and received and dispatched available light mouth), no matter whether the configuration available light mouth annexation on it clashes with the annexation of other light mouths that do not dispose, think that all this veneer is that configuration is available.The relation of connection status and conflict type shows as: connection status is the available veneer of configuration, may exist configuration to connect conflict or available connection conflict; And connection status is the available veneer of connection, and the conflict type can only be not have conflict.
For example, the same light mouth from the frame veneer of regulation must with main frame on accordingly same be connected veneer and be connected.If detect light mouth 0 (disposing) and be connected veneer A and join, this is to conform in the annexation of configuration interface configuration with the user, thinks that then 0 configuration of light mouth is available, also can think the inserting from connecting veneer A from frame of user expectation light mouth 0 place; If detect light mouth 1 and be connected veneer C and be connected, to conflict mutually with light mouth 0, this and rated condition are not inconsistent, and are not inconsistent with user's original meaning yet, and promptly veneer exists configuration to connect conflict.For whole veneer and since existed user expectation, the available light mouth of configuration, this veneer just can participate in business so, so whole veneer is that configuration is available, being light mouth 1 can not bearer service.
Be top situation equally, if not configuration of light mouth 0 is by inserting from the connection veneer A or inserting by connecting veneer C, so veneer does not have the configuration available port and has available connection conflict because can't determine user's original meaning then, whole veneer connects unavailable, can not participate in business.
Three, judge from frame
According to the veneer check result, check two veneers from about the frame, and mark is from frame connection status and conflict type:
3-1), then should there be available connection conflict (alarm) from frame if the available light mouth of connection of the same position of two veneers is not connected on the port of the same position on the connection veneer on the main frame with main and standby relation;
3-2) if two veneers have at least a configuration available, then should be available from the frame configuration, otherwise change 3-5 over to);
3-3) if the available veneer of configuration exists the configuration of veneer to connect conflict, then judge and to exist configuration to connect conflict from frame; Otherwise
3-4), there is conflict between " connecting available light mouth ", thereby makes and " veneer " to have " available connection conflict ", then judge and to have available connection conflict from frame if there are some " connecting available light mouth " in the available veneer of configuration;
3-5) if two veneers have at least a connection available, and should there be available connection conflict from frame, then should be available from the frame connection, otherwise
3-6) judging should be unavailable for connecting from frame.
According to the present invention, after having carried out above-mentioned judgement, can further make come into force (step 305) that is judged as legal annexation.So-called coming into force is meant through after the legitimacy detection, makes the available light mouth of detected connection participate in the process (dispose available light mouth and all participate in service bearer) of service bearer.This processing procedure has two kinds of methods to select:
Automatically come into force: after detection and satisfying condition, connect available light mouth and just can participate in service bearer automatically, when connection is unavailable, withdraw from service bearer.
Manually come into force: the available light mouth that satisfies condition does not participate in service bearer at once, need wait until that equipment management personnel comes into force it with configuration order on configuration interface, the light mouth that this mode comes into force will deposit in the configuration database, become the part of user's configuration data, connect available light mouth and also just upgrade to configuration available light mouth.Equally also needing the user could remove with configuration order on configuration interface comes into force.
According to one embodiment of present invention,, following any class light mouth is come into force, and participates in service bearer by the automatic or manual mode:
1) configuration available and do not exist from frame configuration connect the configuration from the frame of conflict or available connection conflict available and do not exist configuration to connect the veneer of conflict or available connection conflict and connect on the available veneer all connect available light mouths;
2) all that connect the available available veneer of connection from frame connect available light mouths.
More than the preferred embodiments of the present invention are described in detail for illustrative purposes; but those of ordinary skill in the art is to be appreciated that; in scope and spirit of the present invention; various improvement, interpolation and replacement all are possible, and all in the protection range that claim of the present invention limited.
