Abstract
The invention provides a method for online safely upgrading a networking equipment firmware, belonging to the application field of software technology. During upgrading, first, signing an upgrading communication protocol with a party requiring firmware upgrading, and determining data packet format, beginning marker, finishing marker, equipment number and upgrading code, then, running upgrading software on a control host, with the upgrading method comprising the following steps: 1) the host is started to detect that whether the upgrading code of the firmware is valid or not, and the upgrading software is sound or not; 2) if the upgrading code is valid and the upgrading software is sound, the upgrading software opens an appointed port, a host computer transmits a firmware upgrading identification data packet to be communicated with a lower computer, and the upgraded lower computer in the network returns the information after the upgraded lower computer determines the firmware upgrading identification; 3) communication is successful, the host computer partitions and transmits the firmware upgrading code to upgrading equipment to start a firmware upgrading process; 4) all codes complete transmission, the upgrading software transmits an upgrade complete command packet to inform restoration of the upgraded equipment so as to start normal operation.
Description
Technical field
The present invention relates to a kind of safety on-line upgrade method of networking equipment firmware, belong to the software engineering application.
Background technology
The method of electronic equipment firmware upgrade mainly contains following several in the existing group network system: the mode of A, employing special use or multi-functional programmable device, need open device housings, and take off microprocessor and carry out firmware upgrade; B, employing ISP are the mode of in-system programming, need equipment to reserve special-purpose upgrade interface; C, employing 1AP can not need dismantle the existing communication interface of equipment utilization and carry out the upgrading of firmware promptly in the mode of application programming.More than several modes with IAP mode optimum when carrying out firmware upgrade, but if in the networked system several at least, the firmware upgrade of tens up to a hundred equipment at most, wasting time and energy is the comparison distinct issues.
Summary of the invention
At the defective of prior art, the invention provides a kind of safety on-line upgrade method of networking equipment firmware.
A kind of safety on-line upgrade method of networking equipment firmware at first carries out firmware upgrade side's signature upgrading communications protocol with needs, and is clear and definite: data packet format, opening flag, end mark, device number, upgrade code; Be to move upgrade software on the host computer at main control system then, upgrade method is as follows:
1) start, whether detection firmware upgrade code is effective, whether upgrade software is intact;
2) upgrade code is effective, upgrade software is intact, and upgrade software is promptly opened designated port, and host computer sends the firmware upgrade identification data packet and slave computer is promptly got in touch with, and the slave computer that is upgraded in the network is confirmed firmware upgrade sign back return information;
3) get in touch with successfully, host computer sends to the equipment of being upgraded successively with firmware upgrade code piecemeal, the beginning firmware upgrade process;
4) all codes all are sent completely, and upgrade software can send upgrading and finish order bag notice and be upgraded device reset, the beginning operate as normal.
The present invention has the following advantages:
1, need not dismantle device housings, save the trouble of dismounting casing.
2, need not take out microprocessor, can prevent to contact other chips because of carelessness, cause electrostatic damage.
When 3, certain equipment carries out firmware upgrade, can not influence the operate as normal of other equipment.
4, if main control device is arranged,, can save all firmware upgrade equipment as host computer.
5, can realize the telesecurity upgrading, issue the client, get final product, greatly reduce volume of services by client's upgrading with encrypting good upgrade code.Because code is encrypted, does not worry that code is plagiarized in the distribution procedure.

Embodiment
Embodiment:
A kind of safety on-line upgrade method of networking equipment firmware, network structure as shown in Figure 1, the upgrade software program flow diagram is as shown in Figure 2.During upgrading, at first carry out firmware upgrade side's signature upgrading communications protocol with needs, clear and definite: data packet format, opening flag, end mark, device number, upgrade code; Move upgrade software then on main control system, step is as follows:
1) start, whether detection firmware upgrade code is effective, whether upgrade software is intact;
2) upgrade code is effective, upgrade software is intact, and upgrade software is promptly opened designated port, and host computer sends the firmware upgrade identification data packet and slave computer is got in touch with, and the slave computer that is upgraded in the network is confirmed firmware upgrade sign back return information;
3) get in touch with successfully, host computer sends to the equipment of being upgraded successively with firmware upgrade code piecemeal, the beginning firmware upgrade process;
4) all codes all are sent completely, and upgrade software can send upgrading and finish order bag notice and be upgraded device reset, the beginning operate as normal.
Claims (1)
1. the safety on-line upgrade method of a networking equipment firmware at first carries out firmware upgrade side's signature upgrading communications protocol with needs, and is clear and definite: data packet format, opening flag, end mark, device number, upgrade code; On main control system, move upgrade software then, it is characterized in that upgrade method is as follows:
1) start, whether detection firmware upgrade code is effective, whether upgrade software is intact;
2) upgrade code is effective, upgrade software is intact, and upgrade software is promptly opened designated port, and host computer sends the firmware upgrade identification data packet and slave computer is got in touch with, and the slave computer that is upgraded in the network is confirmed firmware upgrade sign back return information;
3) get in touch with successfully, host computer sends to the equipment of being upgraded successively with firmware upgrade code piecemeal, the beginning firmware upgrade process;
4) all codes all are sent completely, and upgrade software can send upgrading and finish order bag notice and be upgraded device reset, the beginning operate as normal.
