In order to object of the present invention, technical scheme and beneficial effect are described better, below based on above-described embodiment, composition graphs 8 ~ 10 introduces three application examples of the present invention, is described in further detail the enforcement of technical solution of the present invention.

Region breeding needs attendant first to determine a key territory, then distribute by networking planning the region that in key territory, all network element device MCC interfaces connect, then by opening ABR(Area Border Router in key territory, Area Border Router) the region breeding function of MCC interface that network element is connected with non-key territory, from this ABR network element (the border network element namely in above-described embodiment), all network elements in non-key territory from the close-by examples to those far off configure automatically, layoutprocedure hop-by-hop carries out, and whole process is without the need to manual intervention.

Application example one

For the NE1 network element in territory key in Fig. 9 to connected non-key territory AREA2, set forth region reproductive process.For the convenient PTN device opening function of support, all devices acquiescence opens DCN(data communication network, Data Communication Network) function, and when physical port be connected and after being in up state, DCN function will create MCC interface automatically.Each MCC interface acquiescence on a network element device is in same territory.As shown in Figure 8, the non-key territory breeding flow process of this application example is as follows:

The first step, determines a key territory, for network elements all in key territory distribute key territory MCC interface and non-key territory MCC interface, as step S201:

Step S201, backbone area is disposed.

Concrete, for key domain network element NE1 ~ NE4 distributes each MCC interface area respectively.For network element NE1, because the MCC13 interface of network element NE1, MCC20 interface are connected with the network element device in key territory, the region ID of these two MCC interfaces is configured to 0.0.0.0, representative be key territory; Because MCC1 interface, MCC12 interface are all connected with AREA2, the region ID of these two MCC interfaces is configured to 0.0.0.2, representative be non-key territory.

According to said method configure the region ID of each MCC interface of network element NE2 ~ NE4 successively.

Second step, opens the region breeding function of the non-key territory MCC interface of ABR network element in backbone network, and the MCC interface having opened region breeding function breeds request message from neighbours' network element sending zone, trend connected non-key territory, as step S205:

Step S205, opens the region breeding function of the MCC interface of ABR network element.

Concrete, the region breeding function of the non-key territory MCC interface of network element NE1 is opened.Because MCC1 interface, MCC12 interface are all connected with same non-key territory, so the region breeding function under only needing to open one of them MCC interface.Here to open the region breeding function under MCC1 interface, control area is not needed to breed nodes herein, need region to be bred nodes and be configured to an infinite value, after region breeding function is opened, MCC1 interface is to its neighbours' network element NE5 sending zone breeding request message, payload segment carries the information such as this MCC interface area ID, area type, and area type refers to the area type information of defined in ospf protocol, does not describe in detail herein.

3rd step, after non-key territory neighbours' network element receives region breeding request message, ROUTER-ID in first checking prediction message is non-after oneself, this network element each MCC interface affiliated area is determined according to this request message, open except with upstream network element interface except the region breeding function of all MCC interfaces, and sending zone breeding request message, simultaneously upstream network element return response message.After upstream network element receives response message, close self global area breeding function and MCC interface area breeding function.

Step S210, S215, S220, S225 are shown in step decomposition.

Step S210, neighbours' network element completes the territory configuration of MCC interface.

Concrete, the region ID of MCC interfaces all on this network element is revised as 0.0.0.2 according to load information after receiving region breeding request message by network element NE5.

Step S215, neighbours' network element opens the region breeding function of MCC interface.

Concrete, network element NE5 opens the region breeding function of all MCC interfaces on this network element except MCC2 interface, namely automatically opens the region breeding function of MCC3, MCC10 interface.After this region breeding function is opened, network element NE5 breeds request message by MCC3, MCC10 interface to its downstream neighbor network element NE8, NE6 sending zone immediately, the payload content of the region breeding request message that request message payload segment adopts the MCC1 interface copying network element NE1 to send.Meanwhile, network element NE5 return response message is to network element NE1, and response message payload content is the territory configuration information of network element NE5.After the response message that network element NE1 receives, it is verified, if confirm, territory has been disposed, and closes global area breeding function (see step S230), if configuration information verification in territory is not passed through, then while the breeding function of closedown global area, also will notify attendant (see step S235) with alarm form

Step S220, downstream neighbor network element completes territory configuration.

Concrete, after network element NE8, network element NE6 receive the region breeding request message of network element NE5, the region ID of all MCC interfaces of this network element of amendment is 0.0.0.2 separately.

Step S225, downstream neighbor network element opens the region breeding function of MCC interface.

Concrete, network element NE8, network element NE6 open corresponding MCC interface area breeding function separately.Concrete, the region breeding function of network element NE8 unlatching MCC5 interface, network element NE6 open the region breeding function of MCC8 interface, MCC11 interface.Network element NE6 breeds request message to network element NE7, network element NE1 by the automatic sending zone of breeding function interface of opening, and to network element NE5 return response message, after the response message that network element NE5 receives, it is verified, if confirm, territory has been disposed, and closes global area breeding function (see step S240), if configuration information verification in territory is not passed through, then while the breeding function of closedown global area, also will notify attendant (see step S245) with alarm form.

The ROUTER-ID verified in the region breeding request message that network element NE6 sends due to network element NE1 be oneself ID, and network element NE1 does not do territory configuration modification, directly replys response and offers network element NE6, network element NE6 closedown global area breeding function;

Because network element NE6, network element NE8 can to network element NE7 sending zone breeding request messages, can respectively to network element NE8, network element NE6 return response message after follow-up network element NE7 processes based on the request message received, NE8, NE6 close respective global area breeding function.When network element NE7 again by the MCC interface opening region breeding function of local terminal to respective network elements (i.e. network element NE8, network element NE6) sending zone breeding request message time, because network element NE8, network element NE6 global area breeding function are closed, network element NE8, network element NE6 directly reply response message, require the global area breeding function of closing NE7, in AREA2 territory, the area information of all network elements has configured automatically.

Present networks also needs the area information configuring all network elements in AREA3 territory, non-key territory, opens the MCC21 interface area breeding function of network element NE3, automatically completes the area information configuration of all network elements in this region.

So far, in Fig. 9, all non-key domain network element regions reproductive process terminates, and all non-key domain network element territories have been disposed.

Application example two

In this application example, to elaborate in Figure 10 each network element region reproductive process in AREA2 ~ AREA5, the network scenarios comprised in Figure 10 has:

An ABR network element band more than 2 non-key territories, as network element NE1, network element NE3;

Two ABR network elements are connected with same non-key territory, as network element NE1, network element NE2 are connected with non-key territory AREA4;

Non-backbone area is a strand;

Non-backbone area is a closed loop, and this topology is described in application example one;

Dilatation is carried out to existing network.

The non-key territory breeding flow process of this application example is as follows:

The first step, determines backbone area, for network elements all in backbone area distribute key territory MCC interface and non-key territory MCC interface, distributes backbone area network element NE1 ~ NE4 each MCC interface area.For network element NE1, MCC2 interface, the MCC3 interface of network element NE1 are connected with key territory equipment, be configured to the region ID:0.0.0.0 representing key territory, MCC9 interface, MCC20 interface are all connected with AREA2, these two MCC interface configuration are the region ID:0.0.0.2 representing non-key territory, MCC36 interface is connected with AREA4, and the region ID of its interface is set to 0.0.0.4.

According to said method dispose the region ID of each MCC interface of network element NE2 ~ NE4 successively.

Second step, starts to breed AREA2 region.First open the region breeding function under the non-key MCC9 interface of network element NE1, region breeding NE quantity is configured to infinite value, MCC9 interface is from its neighbours' network element NE5 sending zone, non-key territory of trend breeding request message, and payload segment carries the information such as the region ID of this MCC interface, the area type of this network element.

3rd step, after network element NE5 receives region breeding request message, according to all MCC interface area ID on load information amendment network element, consistent with the region ID of the MCC interface in load information, and open the region breeding function of all MCC interfaces except MCC10 interface, then return response message is to network element NE1, response message payload content is the territory configuration information of network element NE5, after network element NE1 receives response message, confirm that territory has been disposed and then close global area breeding function, if configuration information verification in territory is not passed through, then while the breeding function of closedown global area, also to notify attendant with alarm form,

Network element NE5 opens the MCC interface of region breeding function to its downstream neighbor network element NE8, NE6 sending zone breeding request message, the request message payload content that request message payload segment sends under adopting and copying the MCC interface of network element NE1.The region that the operation that network element NE8 and network element NE6 repeats network element NE5 completes all network elements in AREA2 is bred.This process application example one is just the same.

4th step, starts to breed AREA4 region.Because AREA4 is connected with ABR network element NE1, NE2 simultaneously, when breeding AREA4, needing the global area breeding function of manually first closing one of them ABR network element, closing the global area breeding function of network element NE2 herein.Open the region breeding function under the MCC36 interface of network element NE1, because network element NE1 once performed region breeding operation, so now need to check whether network element NE1 global area breeding function closes, if be closed, need manually global area breeding function to be opened; MCC36 interface is to network element NE10 sending zone breeding request message, network element NE10 revises each MCC interface region ID after receiving request message is 0.0.0.4, namely consistent with the region ID of MCC36 interface, open the region breeding function of MCC30 interface, return response message is to network element NE1 simultaneously, after network element NE1 receives response message, after carrying out associated check, close closed region breeding function.

5th step, the MCC30 interface of network element NE10 sends request message to network element NE9, after network element NE9 receives request message, revise the area configurations of each MCC interface, open the region breeding function of MCC34 interface, return response message is to network element NE10 simultaneously, after network element NE10 receives response message, after carrying out associated check, close global area breeding function.MCC34 interface sends request message to network element NE2, because network element NE2 global area breeding function is closed, network element NE2 is not to request message response, and directly reply response message to network element NE9, network element NE9 closes the global area breeding function of this network element after receiving response message.

6th step, starts to breed AREA3 region.AREA3 region reproductive process is identical with AREA2 region reproductive process.

7th step, starts to breed AREA5 region.Check whether network element NE3 global area breeding function is closed, if be closed, needs manually opened.Open the region breeding function of MCC31 interface, MCC31 is to network element NE14 sending zone breeding request message, after network element NE14 receives request message, revise the area configurations of each MCC interface, open the region breeding function of MCC33 interface, return response message is to network element NE3 simultaneously, after network element NE3 receives response message, after carrying out associated check, close closed region breeding function.

8th step, the MCC33 interface of network element NE14 sends request message to network element NE15, after network element NE15 receives request message, the region ID revising each MCC interface is consistent with the region ID of MCC33 interface, because this network element only has a MCC interface, so do not need the region breeding function of opening other MCC interfaces, direct return response message is to network element NE14, after network element NE14 receives response message, after carrying out associated check, close closed region breeding function.

In addition, dilatation network element region reproductive process in AREA5 is in Fig. 10 as follows:

The first step, disposes physical connection by network element NE16, network element NE17 by between planning network topology and network element NE15;

Second step, opens the global area breeding function of network element NE14 and network element NE15, and opens the region breeding function of the MCC33 interface of network element NE14;

3rd step, message is sent request to network element NE15 by MCC33 interface, network element NE15 revises the region ID of all MCC interfaces, comprise the area configurations of MCC37 interface, MCC39 interface, open the region breeding function of these two MCC interfaces, these two MCC interfaces send request message respectively to network element NE17, network element NE16; Network element NE15 return response message, network element NE14 receives the laggard line correlation process of response message;

4th step, network element NE17, network element NE16 revise the region ID of respective all MCC interfaces after receiving request message, and open MCC41 interface, MCC42 interface area breeding function respectively, message is sent request respectively to network element NE16, network element NE17, simultaneously to network element NE15 return response message, network element NE15 closes global area breeding function, namely closes the region breeding function of MCC37 interface, MCC39 interface;

5th step, after network element NE16, network element NE17 receive the request message of opposite end, amendment territory configuration information, and reply response message mutually, then close oneself global area breeding function and MCC interface area breeding function, region reproductive process terminates, and completes the dilatation of new log equipment.

So far in accompanying drawing 10, all non-key regional network units region reproductive process terminates, and all non-key domain network element territories have been disposed.

The embodiment of the present invention described realizes method that non-backbone area breeds automatically and relevant device, improve and conveniently open the efficiency opened with PTN network under plug and play scene, compared with existing method regional deployment can only having been gone to operate by manual type, save a large amount of manpower and financial cost, greatly shorten network opening required time, improve efficiency and operator's satisfaction of network opening.Example lifted in the introduction, manual operation needs about 7 hours, according to the method for breeding automatically, only need the region breeding function of manually opened 17 MCC interfaces on the network element of border, if open a MCC interface area breeding function to need 30 second time, the Region dividing then completing 850 network elements disposes the time only needing about 8 minutes, and efficiency comparatively manual operation improves nearly 60 times, and when network size is larger, its advantage is more obvious.

By the explanation of embodiment, should to the present invention for the technological means reaching predetermined object and take and effect be able to more deeply and concrete understanding, but appended diagram be only to provide with reference to and the use of explanation, be not used for being limited the present invention.
