Description
Technical field
It is suitable more particularly to one kind the present invention relates to a kind of method and system for realizing more boards and multiple data channel management
For the more boards of realization of data communication field and the method and system of multiple data channel management.
Background technique
High capacity communication equipment such as SDH, OTN, PTN etc. uses rack and panel construction substantially at present, and a subrack includes multiple plates
Card, for the ease of managing and maintaining, it is desirable to provide local and remote administration function.Administrative unit is responsible for acquiring and handling local pipe
Reason information is simultaneously uploaded to administrative center, while administrative unit is also responsible for receiving and handling the administration order that network management center issues, and
Corresponding board is assigned to execute.Since network structure becomes increasingly complex, bandwidth resources are in short supply, therefore most of communication equipment mentions
For multi-direction, embedded management data channel, to transmit management information to remote management center.Embedded management data channel
Using the fractional bandwidth of system line transmission channel, physical interface is distributed on respective lines interface processing board, and information
Processing is then completed by administrative unit.
1, current communication equipment is handled by the way of Fig. 1 substantially:
2, acquisition or received management information are mainly stored in management information storage area, generally with database, file or other
Data format exists.
3, the data format that data packet mainly uses both sides to appoint carries out information transmitting, can use reference format such as IP
User-defined format can also be used in message；Group is wrapped when transmission, and when reception unpacks.
4, data link layer mainly guarantees the transmission of data within the physical layer in a manner of frame, its completion data block identification,
Demarcation, error checking and correction and certain transmission control, can use reference format such as HDLC, user-defined format can also be used；When transmission
Framing, frame decoding when reception.
5, the main adaptation for completing physical media of physical layer signal processing, as level translation, power control, clock recovery,
Encoding and decoding etc..
6, multiplex/demultiplex is that embedded management passage information is mixed/separated with customer information in transmission channel, is embedded
Management passage uses reserved overhead byte, management data packet or wavelet length etc.；Receiving end is out of in minor channel information stream extract
Embedding management passage information.
There are mainly three types of transmission modes for management category information at present:
1, active upload information: the embedded management passage information for such as alerting, receiving, generally from board to administrative unit
Card application is sent, and is retransmited after being allowed, and sends confirmation message by administrative unit card after receiving.
2, query information: such as performance number, status information send data sending request from administrative unit card to board, then
It is sent by board, confirmation message is sent by administrative unit card after receiving.
3, lower photos and sending messages: the embedded management passage information such as prepared, control, sent is sent out from administrative unit card to board
It send data to send order, is sent by administrative unit card, confirmation message is sent by plate after receiving.
Current mechanism there are the shortcomings that:
1, all data transmission and reception needs group packets and unpacking, and need to send the corresponding command and carry out hand shaking, such as
Request, response；Process flow is complex, and occupying system resources are more, efficiency of transmission is lower, as shown in Figure 2.
2, data transfer procedure needs the side's of sending and receiving host to participate in jointly, and information is transmitted by data packet, wraps at one
Transmit process cannot terminate, and cannot respond to higher priority data transmission requests at this time, influence manage card host processing power and
Management quality.
3, embedded management data channel is unified is completed by administrative unit, and administrative unit card is needed to increase when system upgrade
Hardware interface circuit increases board type, is unfavorable for producing and safeguard.
The reason of formation:
Since the serial ports such as 485,232 and ethernet technology are more mature, most of CPU are provided which serial line interface and network interface,
And support multiple access, therefore between the business board and administrative unit of most of producer's communication equipments data communication frequently with serial ports
Or network interface connection.Since serial ports and embedded management data channel only provide bit transmission information, each producer using standard or
Off-gauge frame encapsulation and data packet format, to meet big data quantity communication.Since network becomes increasingly complex, embedded management number
Multiple directions are connected as main channel according to channel, the communication products route mouth of early stage is less, and middle and high end CPU can provide multiple
Data channel interface is often individually connected using each embedded data channel with administrative unit, and board management passage uses serial ports
Bus is connect with administrative unit, system structure can be made relatively simple in this way, therefore this design method has followed in many producers.
As route number increases, when cpu data channel interface cannot be met the requirements, often carried out using programming device or special chip
Extension.
