According to the number of IP addresses requested by MAC, the IP addresses within a specific IP address field are automatically assigned, and moreover, the IP addresses assigned for the same device are continuous IP addresses; the continuity of the IP addresses assigned for each device is ensured, and the assigned IP addresses can be manually reassigned or deleted, i.e. later-stage management.
Description
Technical field
The present invention relates to the automatic allocation manager technology of network ip address; In particular; Be that a kind of technology that is used for being implemented in the automatic allocation manager in IP address that realizes management equipment on the network realizes, native system is particularly useful for the IP address of the various device in this particular system of Network Video Surveillance and distributes automatically and management.
Background technology
Video monitoring system is the important component part of safety and protection system, is a kind of powerful general defensive character in all files.Video monitoring is widely used in many occasions so that it is directly perceived, convenient, the information content is abundant.In recent years; Along with the particularly rapid raising of the network bandwidth, computer process ability and memory capacity and the appearance of the various usable video information processing technologies of the continuous development of modern science and technology; The video monitoring technology also has significant progress; Video monitoring has got into totally digitilized cybertimes, receives people's attention and concern day by day.
Future video supervisory control system development trend is that the monitoring scale is increasing; Networking requirement is more and more; Business is more and more abundanter; This just needs supervisory control system to turn to the basis with digitlization, networking, intelligence to make up monitoring network platform, and can solve safety, QoS, the Media Stream multicast that extensive networking brings and problem, meaningful marginalisation and network integration trend such as interconnect.
Based on network video monitoring system is the phase III of video monitoring development, the promptly digital monitoring epoch.Video is digital signal when the front end image capture device is exported; And be transmission medium with the network; Based on international ICP/IP protocol; Adopt stream media technology to realize video multiplexed transmission on the net, and through being located at online network virtual (numeral) matrix main control system (IPM), realize functions such as commander, scheduling, storage, authorization control the whole video supervisory control system.。
Just be based on international ICP/IP protocol standard, so third generation network video monitor and control system is very high for the requirement of IP address, each equipment in the network all needs independent IP address just can work normally.And along with the continuous expansion of supervisory control system scale, intrasystem various device is more and more, uniform and effective management is carried out in the IP address of intrasystem each equipment will become particularly important.
Present LAN IP address distributorship agreement mainly is the DHCP agreement; In the local area network (LAN) all need the equipment of distributing IP address; After powering on, will get in touch through DHCP agreement and Dynamic Host Configuration Protocol server, distribute corresponding IP address information to give equipment by Dynamic Host Configuration Protocol server.
Because general DHCP service agreement must start server program earlier before each device start, and equipment is each all need ask the distributing IP address when starting, and each IP address allocated maybe be different.And the process of distributing IP address all is automatic completion, after the distribution, and manual work have no idea to carry out again secondary distribution and management.Simultaneously, if Dynamic Host Configuration Protocol server paralysis in a single day, all devices in the whole system can not be worked.On the other hand, because the comfortable particular requirement of present networks video monitoring system itself, each MAC Address possibly need a plurality of IP of distribution address, and same equipment institute IP address allocated need keep relative continuity.Based on above-mentioned various reasons, traditional DHCP service can not be satisfied the IP address assignment and the management of this particular system of network video monitor and control system.So,, develop the IP address assignment of this particular system of adaptation Network Video Surveillance and the system of management and just arisen at the historic moment according to existing DHCP agreement.

Technical scheme: the automatic allocation manager in IP of the present invention address system comprises following technical essential:
IP number of addresses according to the MAC request is distributed the IP address of particular ip address section automatically, and same equipment institute IP address allocated is one section continuous IP address; Guarantee the continuity of each equipment institute distributing IP address, for the IP address of having distributed, manual work is reallocated and is adjusted or deletion i.e. final-period management.
After the IP address assignment success,, then read original IP address allocated and return to the request end if ask IP address assignment once more;
If there is not continuous assignable IP address, when perhaps available IP number of addresses is not enough, system will point out the user to need artificial adjustment to redistribute;
The IP address of system assignment will write background data base, if write failure, system provides manual work to write database manipulation, can preserve miss data automatically simultaneously;
Write the IP address information of database, system can automatically preserve backup, simultaneously, the artificial function that imports derived data storehouse IP address information is provided also, prevents that system crash IP address information from losing;
For the IP address of having distributed, the IP number of addresses of having distributed can be freely adjusted in manual work, in the time of adjustment, also is that an all IP address of equipment is adjusted together, guarantees the continuity of the IP address of an equipment;
For the IP address that need not use,, delete unnecessary IP address information through manual type.
The step of handling automatic distribution of various terminal device IP address and later stage labor management is following:
Steps A .IP address allocation system is received the IP address request;
Whether step B.IP address allocation system see and distribute according to the content search database in the request message, if distribute, reading database then sends IP address allocated information once more and gives the request end;
If step C. does not distribute, then Query Database sees whether have in available continuous IP address or the database whether have enough IP available number of addresses;
If step D. does not exist available continuous IP address information or available IP number of addresses not enough, system will point out the user to distribute failure, need artificial adjustment before IP address allocated carry out manual allocation again;
If step e. there is available IP address information, then distributes the IP address automatically and form to receive the response accordingly and send to the request end;
Step F. send after the completion of IP address assignment message, system will carry out database and write operation, and IP address allocated information is write background data base;
Step G. reads the database information that has just write, and whether writes success with the inspection database;
If step H. writes failure, then carry out F, two step 3 of G are inferior;
If step I. fails for three times, then point out customer data base to write failure, need artificial warehouse-in;
Step J. system will distribute the IP address of success to be presented at the interface in real time automatically, when the user double-clicks a certain IP address of equipment, can revise the IP address of having distributed once more through manual type;
Step K. if a certain device damage, its IP address are not being used, and the user deletes the IP address information of having distributed through successful IP address allocated interface;
Step L. is for the IP address information of automatic distribution failure, and system is shown to the interface of automatic distribution failure in real time with request message, when the user double-clicks a certain message, and will be through manual type distributing IP address information;
Step M. is if automatic IP address allocation the time; Write failed database; System will be shown to this IP address information the interface of warehouse-in failure in real time, when the user double-clicks a certain IP address information, will this IP address be put in storage once more through the mode of manual work.
Beneficial effect: compared with prior art; The present invention has introduced a MAC Address can distribute a plurality of IP addressing mechanisms simultaneously, simultaneously, and to the IP address of same devices allocation; Guarantee its continuity; And in a single day after distributing successfully, relative fixed, this has well adapted to the video network supervisory control system.
In addition; The present invention also provides the artificial operation of redistributing the IP address; Help can revising IP address allocated easily when later upgrading of system and networking mode change, provide automatic distribution failure to need the interface of distributing manually simultaneously, the warehouse-in failure needs the interface of artificial in-stockroom operation; Improved the degree of flexibility of system to a certain extent greatly; Can be according to the subsequent user different demands, the upgrade requirement of system, the change of networking mode is from new settings IP address and unified IP address maintenance management.
And, in case after the maximum benefit of the present invention is to distribute successfully, will ask the IP address no longer again in the time of device start, so, also do not influence the normal operation of the equipment of having distributed the IP address even service end IP address assignment system does not move.Guaranteed the relative independentability of system.Simultaneously, the IP address of IP address of having distributed and warehouse-in failure, system will be saved in file automatically, and when collapse takes place in system, system will be written into the IP address information of backup automatically.
