Embodiment
Below in conjunction with Fig. 1～Fig. 2 the embodiment of the invention is described in detail.Fig. 1 is two network diagram that the networking unit connects.These two networking unit are used for connecting different monitoring territories.Fig. 2 is the network building-block of logic of the device of a kind of IP of renewal address in the unit of the present invention.The device of this renewal IP address comprises NetBIOS processing module, foreign lands address processing module, self address processing module.The detailed execution mode of the embodiment of the invention is described below.
The NetBIOS logon message of transmission self territory coding and IP address supplies the corresponding relation of this territory coding of Wins server record and IP address to the Wins server after reaching the standard grade in step 1, networking unit.Step 1 is carried out by the NetBIOS processing module.
Like Fig. 1, unit A is an example with networking, and this networking unit is arranged in cross-domain video surveillance network, and networking is after unit A reaches the standard grade, and sends the NetBIOS logon message of self territory coding and self IP address.The territory coding that Wins server in the network receives the unit A that will network behind this logon message is recorded in local for other networking unit (like the networking unit B) the IP address lookup through NetBIOS name initiation distich net unit A with IP address corresponding relation.After the networking unit B is reached the standard grade also as networking send the NetBIOS logon message of self territory coding and self IP address the unit A so that encode and IP address in its territory of Wins server record.Territory coding is as the unique identification of networking unit in the cross-domain video monitoring system, and the netbios name that is used to constitute the networking unit is registered on the Wins server.
The reach the standard grade territory coding of inquiry foreign lands networking unit in the outer domain list of self, back of step 2, networking unit initiates to be encoded to networking territory, unit, foreign lands the NetBIOS inquiry of NetBIOS name, with the IP address of this networking unit, foreign lands of obtaining the Wins server feedback.Step 2 is also carried out by the NetBIOS processing module.
The territory coded message of networking unit, foreign lands is preserved in the networking unit in the domain list outside this locality, this information generally is pre-configured.Networking is after unit A reaches the standard grade, and inquires about the territory coding of self networking unit, territory, outer domain list China and foreign countries, such as inquires the territory coding of networking unit B, and networking unit A just is encoded to NetBIOS name initiation NetBIOS with the territory of networking unit B and inquires about.If networking unit A also inquires the territory coding of networking unit C except encoding in the territory that inquires the networking unit B certainly, the territory with networking unit C is encoded to NetBIOS name initiation NetBIOS inquiry equally.The corresponding IP address of coding, territory of Wins server feedback networking unit B.Networking unit A has just obtained the IP address of networking unit B like this.
Step 3, networking unit upgrade the IP address of the networking unit, foreign lands in the outer domain list.Step 3 is carried out by the foreign lands address processing module.
Networking unit A adds the IP address of networking unit B in the outer domain list of self behind the IP address that obtains the networking unit B.If networking unit A is positioned at the subordinate territory, the networking unit B is positioned at the higher level territory, and the unit A that perhaps networks belongs to territory at the same level with the networking unit B, and networking unit A is that purpose IP registers to the networking unit B with the IP address of networking unit B.After registration was accomplished, networking unit A just was in interconnected state with the networking unit B.Follow-up, when change takes place in the address of networking unit A, be purpose IP directly just with the IP address of the networking unit B in self outer domain list, send address change and notify message.
After step 4, networking unit and networking unit, foreign lands are not set up interconnecting relation and are inquired the IP address of networking unit, foreign lands; Transmission is purpose IP with the IP address of this networking unit, foreign lands; Self IP address is the notice message of source IP, and this notice message carries the territory coding of this networking unit self.Step 4 is by self address processing module execution.
Still be that example is set forth with networking unit A with the networking unit B.The IP address that the networking unit B also can step 1 when reaching the standard grade, the mode of step 2 is obtained networking unit A.If but networking unit A online after power-down rebooting again, preserved the IP address before the networking unit A power-down rebooting on the networking unit B, and networking unit A is restarted IP address, back variation possibly taken place, but the unit B of networking is not known also.So; In order to let the networking unit B know this situation; The networking unit A back (take place interconnected with the networking unit B this moment) of reaching the standard grade, behind the IP address that obtains foreign lands networking unit B, sending with this IP address is purpose IP through the NetBIOS mode; Self IP address is the notice message of source IP, and this notice message carries the territory coding of networking unit A; The networking unit B is received this notice message; Judge that earlier whether the territory of carrying in this message encode outside self in the domain list; If, obtain the IP address of the networking unit A of Wins server feedback thereby the territory in the transmission notice message is encoded to the NetBIOS inquiry of NetBIOS name, otherwise do not handle.Judge whether this IP address is consistent with the source IP address of notice message behind the IP address of the networking unit A of networking unit B acquisition Wins server feedback; If it is consistent; The networking unit B changes to the source IP address of notifying message with the corresponding IP address of coding, networking A territory, unit in self outer domain list; Further, the networking unit B can be sent confirmation message to networking unit A; If inconsistent, then do not handle.
When interconnecting relation is set up in step 5, networking unit and networking unit, foreign lands and the IP address, unit of self networking changes; The NetBIOS logon message that sends self territory coding and after changing IP address is to upgrade the record on the Wins server; And after outside self, inquiring the IP address of networking unit, foreign lands the domain list; Transmission is purpose IP with the IP address that inquires; With IP address after changing, this networking unit is the notice message of source IP, and this notice message carries the territory coding of this networking unit self.Step 4 is by self address processing module execution.
Is example with networking unit A with the networking unit B; Take place when interconnected with the networking unit B at networking unit A; All preserve the other side's IP address in the outer domain list of networking unit A and networking unit B; The I P address of networking unit A because certain reason change taken place variation (such as, the DHCP lease of networking unit A is expired, Dynamic Host Configuration Protocol server has distributed a new IP address for networking unit A); The NetBIOS logon message that networking unit A sends self territory coding and after changing IP address to be upgrading the record on the Wins server, is the correct IP address of networking unit A with what guarantee that other inquiry inquires; In addition; Networking unit A need be with the message informing networking unit B of self IP address change: networking unit A inquires foreign lands and networks behind the IP address of unit B the domain list from self outside; Transmission is purpose IP with the IP address of networking unit B; A IP address after changing, this networking unit is the notice message of source IP, and this notice message carries the territory coding of networking unit A.If networking unit A also possibly find the IP address of other networking unit, foreign lands from the outer domain list of self, send the notice message for equally these networking unit, foreign lands.The networking unit B is received this notice message; Judge that earlier whether the territory of carrying in this message encode outside self in the domain list; If; Thereby transmission obtains the IP address of the networking unit A of Wins server feedback with the NetBIOS inquiry that the territory in the notice message is encoded to the NetBIOS name, otherwise does not handle.Judge whether this IP address is consistent with the source IP address of notice message behind the IP address of the networking unit A of networking unit B acquisition Wins server feedback; If it is consistent; The networking unit B changes to the source IP address of notifying message with coding corresponding I P address in networking A territory, unit in self outer domain list; Further, the networking unit B can be sent confirmation message to networking unit A; If inconsistent, then do not handle.
Step 6, networking unit confirm after sending the notice message, in the preset time, whether to receive the affirmation message that networking unit, foreign lands sends; If do not receive, this networking unit resends the notice message.Step 6 is also by self address processing module execution.
Be that to send when notifying message (might this IP not be up-to-date IP to purpose IP in the IP address of the networking unit, foreign lands that networking unit A inquires in domain list self outside; Change has also taken place in the IP address such as the unit B of networking this moment), the networking unit B might can not receive the notice message of networking unit A.After so networking unit A sends above-mentioned notice message; Need to confirm whether this notice message is received by the networking unit B; So just whether monitoring has the affirmation message of receiving networking unit B feedback; If do not receive, networking unit A resends the notice message behind the IP address through NetBIOS inquiry networking unit B territory coding correspondence.In general, the last IP address of NetBIOS is up-to-date.Certainly,, still do not receive confirmation message, then send the notice message once more if the IP address of the networking unit B that networking unit A inquires with NetBIOS is that purpose IP resends the notice message.
After step 7, networking unit receive the notice message that sends networking unit, foreign lands; Whether the territory coding of judging the networking unit, foreign lands that this notice message carries is in the outer domain list of self; The purpose IP of this notice message is the IP address of this networking unit, and source IP address is the IP address of networking unit, foreign lands; If initiate to be encoded to the Net BIOS inquiry of title, with the IP address of this networking unit, foreign lands of obtaining the Wins server feedback with this networking territory, unit, foreign lands; Upgrade the network IP address of unit, this foreign lands in self outer domain list if the IP address of networking unit, this foreign lands of Wins server feedback is identical with source IP address in the notice message that networking unit, foreign lands sends.Step 7 is handled the address by foreign lands networking unit IP and is carried out.
The order of above-mentioned steps 1～step 7 can be adjusted to some extent, in fact describes just with the mode of step and understands for ease, does not represent ordinal relation inevitable between the step.Belong to processing modes different under the different situations such as step 4 and step 5, the actual ordinal relation that does not have strictness.
Networking unit A in the above-mentioned example belongs to reciprocity relation in the present invention with the networking unit B; In the present invention promptly; The execution action of networking unit A can take place on the networking unit B; The execution action of networking unit B also can take place on networking unit A, and the functional module networking unit B that networking unit A has in logic has, and the functional module networking unit A that the networking unit B has in logic also has.Certainly.Just introduced the situation of two networking unit in the example, a plurality of networkings unit can be carried out with reference to the situation of two networking unit equally in the reality.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope that the present invention protects.
