Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of system and method for realizing that board software loads.
Background technology
Along with the development of network service, various network communication equipment is arisen at the historic moment, comprising the multi-service transfer equipment, such as MSTP (Multi-service Transport Platform, multi-service transport platform) equipment.The multi-service transfer equipment not only supports to handle the professional veneer of traditional TDM (Time Division Multiplexing, time division multiplexing), also supports to handle ether, the veneer of ATM data services such as (Asynchronous TransferMode, asynchronous transfer modes).
CPU on the service board (hereinafter to be referred as business board) of multi-service transfer equipments such as MSTP and FPGA (Field Programmable Gate Array, field programmable gate array) etc. multiple device all needs software to work, therefore need on the business board to store for the software of CPU and FPGA use and some configuration files etc., below be referred to as board software.
Because the type of multi-service transfer equipment business boards such as MSTP is many, some data class board software is also huger, and the software kit of whole communication equipment (being the set of all types of board softwares) is usually more than tens Mbytes.Owing to the increase of new features and revise multiple reasons such as original software defect, often need upgrade to board software.Yet transmission room spreads all over wider, distance is very far away between each machine room, and on-the-spot one by one equipment to be carried out updating operation to each machine room be unusual labor intensive material resources.Therefore, can adopt in the mode of the long-range loading of central machine room generally speaking and operate.
We know that the ITU-T suggestion has defined the passage of overhead byte D1～D12 as maintenance management information to the frame structure of SDH (Synchronous Digital Hierarchy, digital synchronous sequence).These D bytes of equipment producer general using constitute physical layer DCC (Data Communication Channel, data communication channel), move ECC (Embedded Communication Channel in the above, the embedded communication passage) agreement or IP agreement, so that transmit the management maintenance information between each network element, the long-range loading of board software is also undertaken by the DCC passage.
In network communicating system, we can be referred to as network element device with the network device unit with master control borad and business board, and its schematic network structure as shown in Figure 1.
Wherein, the network element device that is connected with network management system is called Gateway Network Element usually.In general network management system directly is connected by Ethernet with Gateway Network Element, uses ICP/IP protocol; The webmaster network element is connected by optical fiber with other network element devices.Gateway Network Element has also played functions such as protocol conversion and route, such as, the ICP/IP protocol of Network Management Equipment is changed into ECC agreement or the IP agreement that communication is used between network element, the information that network management system is issued is forwarded to the purpose network element device.
Shown in 2, network element device generally also possesses a veneer (this veneer is commonly referred to as master control borad) of being responsible for communication and system's control except possessing various types of business boards.In the time of loading monoboard software, network management system splits into packet with the software that loads, and is sent to by DCC on the master control borad of purpose network element device, and master control borad is forwarded on the corresponding business plate by communication bus more then.Business board is saved in board software in the Flash memory devices such as (flash memories) of this plate, and then with software loading in the function corresponding device.Like this, business board resets or when re-powering, just can obtain software and start from this plate Flash and move.
Simply introduce the technical scheme that two kinds of existing board softwares load below.
Technical scheme one: all board softwares that network management system is supported all network element devices in the network earlier break into a software kit, this software kit is issued in the master control borad of each network element device respectively by DCC then, master control borad is according to network element device current business plate kind and business board hardware version numbers, the software that choosing each business board from software kit needs is issued in the business board, business board with software loading in the function corresponding device.
Be not difficult to find out that technical scheme one has following shortcoming:
1, because all board softwares that all network element devices in the network will be supported leave in the master control borad as a software kit, therefore the master control borad memory space is required often to need tens space than higher, cause the anxiety of master control borad memory space;
2,, therefore increased the cost of master control borad because master control borad need use jumbo memory device;
3, network management system need be issued to the whole software bag in the master control borad of each network element device, so the software loading time is very long.
Technical scheme two:, in the master control borad of each network element device, increase a CF (Compact Flash, tight type flash memory) card in order not take the memory space of each network element device master control borad.Like this during loading monoboard software, the software kit that all board softwares that network management system can be supported product break into is issued in the CF card of network element master control borad by DCC, master control borad carries out corresponding software upgrading operation to business board automatically again according to network element current business plate kind and business board hardware version numbers.
Be not difficult to find out, to have following shortcoming though technical scheme two has reduced the requirement of master control borad memory space:
1, the master control borad owing to each network element all needs to support the CF card, so cost is higher;
2, long not solution of problem of software loading time;
3, the CF card is too high to the master control borad dependence, when the software kit increase needs expansion CF card capacity, need take off master control borad and can change the CF card, may impact business like this; Because the prematurity still of CF card technique, the CF card is short useful life in addition, and it is wrong, unstable read-write to occur through regular meeting, so the fail safe of software loading, reliability can't be guaranteed.
