Embodiment two,
See also Fig. 2, another embodiment of the annexation acquisition methods of LA Management Room comprises in the embodiment of the invention:
201, server sends to equipment in telecom network and gathers indication, and to gather title and the address information of bearer network equipment, this bearer network equipment comprises interface IP address information, and this interface IP address information comprises the default gateway address information of this equipment in telecom network;
As shown in Figure 3, server can use transmission control protocol (TCP, Transmission Control Protocol) with the management ip address IP1 of the equipment in telecom network passage that connects, this passage is called " maintenance channel ", use IP2 to communicate by letter between equipment in telecom network A and the equipment in telecom network B, IP2 is called " service IP address " of equipment in telecom network A.In the present embodiment, in the total interface IP address with equipment in telecom network, the corresponding interface IP of the interface that is connected with server address is called the management ip address of this equipment in telecom network.
Can preserve in advance title and the address information of each equipment in telecom network at server.
If the address information of the equipment in telecom network of preserving in server in advance includes only management address information (the IP address that namely links to each other with server), the service address information (the IP address that namely links to each other with bearer network) of equipment in telecom network, before execution in step 201, server can obtain by " maintenance channel " other address information of equipment in telecom network, for example, the default gateway address information IP address of the direct-connected bearer network equipment of equipment in telecom network (namely with).For example, can adopt snmp protocol to send to equipment in telecom network by server gathers indication, carries the OID (for example OID of default gateway address) of the address information that will gather in this collection indication.Before the title and address information of obtaining bearer network equipment from equipment in telecom network, in the uncertain whole network of server which bearer network equipment is arranged, therefore, the title and the address information that need the direct-connected bearer network equipment of first collection and equipment in telecom network, gather title and address information with the direct-connected bearer network equipment of this bearer network equipment according to this address information again, until gathered title and the address information of all bearer network equipment.
In the present embodiment, server is as follows from the specific implementation that equipment in telecom network obtains the title of bearer network equipment and address information:
Before the explanation specific implementation, need to make an explanation to next hop address.The next hop address of router one refers to the interface IP address with the direct-connected router two of router one, and this interface IP address place port is the port direct-connected with router one.As shown in Figure 3, the next-hop address information of router-A is IP5, and the next-hop address information of router B is IP7 and IP4, and the next-hop address information of router C is IP6.
As shown in Figure 3, because the default gateway address information IP3 of equipment in telecom network A is one of interface IP address information with the direct-connected router-A of equipment in telecom network A, so can be sent to equipment in telecom network A by server first and gather indication, comprise IP3 in this indication, to gather title and the address information of bearer network equipment, this bearer network equipment is the bearer network equipment (being router-A) that interface IP address information comprises IP3, and this address information comprises the next-hop address information of router-A at least.
Because the next-hop address information IP5 of router-A is one of interface IP address information with direct-connected another router of router-A, so after the title that collects router-A and address information, server can judge first whether the next-hop address information IP5 of router-A preserves, if do not preserve, another router (being router B) that server is also found and router-A is direct-connected is described, need to after the title and address information of preserving router-A, gather title and the address information of router B.
Until gathered after the title and address information of router C, because router C only has a next hop address IP6, and server judges that IP6 has preserved, determine that interface IP address information comprises that title and the address information of the router (being router B) of IP6 gather, after the title and address information of preserving router C, finish the collection to all-router title and address information.
As shown in Figure 3, the service address information of equipment in telecom network A is IP2, and the default gateway address information is IP3.Because the interface IP address information of router-A comprises IP3, therefore, in step 201, what server will gather is title and the address information (can comprise total interface address information, next-hop address information or physical address information) of router-A.
Server can adopt snmp protocol to send to equipment in telecom network and gather indication.Can preset between server and the telecommunication apparatus internal command code that is used for transmitting snmp message, for example: 0x01 represents to gather the command word of the address information of bearer network equipment, and 0x02 represents to return the command word of the address information of bearer network equipment.
SNMP collection Indication message packet format can define multiple, and the below by the situation that equipment in telecom network A gathers the address information of router-A, illustrates that a kind of SNMP gathers the form of Indication message bag with the server among Fig. 3:
As shown in Figure 4, the form of snmp message bag is followed successively by IP 1 from outside to inside, TCP head, command code, IP 2, User Datagram Protocol (UDP, User Datagram Protocol) head and snmp message, the below is to the explanation that makes an explanation of the form of snmp message bag:
(1) major parameter among the IP 1 comprises: purpose IP address, i.e. and the management ip address of equipment in telecom network A (IP1 among Fig. 3), source IP address is the interface IP address (IP0 among Fig. 3) of server.
(2) the TCP head is to fill in according to Request for Comment (RFC, Request For Comments) 793 standards.
(3) command code is the sign that " maintenance channel " uses between server and the equipment in telecom network, and for example: 0x01 represents to gather the command word of the address information of bearer network equipment, and 0x02 represents to return the command word of the address information of bearer network equipment.Owing to be Information Monitoring, the command code that server is filled at maintenance channel is acquisition code 0x01.Equipment in telecom network A can peel off after IP 1, TCP head, the command code after receiving the snmp message bag that server sends, and then the information according to IP 2 is transmitted to bearer network equipment gathering request.
(4) major parameter among the IP 2 comprises: the interface IP address of the bearer network equipment that gather, the i.e. direct-connected interface IP address of router-A and equipment in telecom network A, namely the default gateway address ip 3 of equipment in telecom network A.
(5) snmp message fill in the consensus standard of following SNMP, comprise title that needs gather and the object identifier (OID, Object IDentifier) of address information, for example, the OID of router rs name is 1.3.6.1.2.1.1.5.0; The OID1.3.6.1.2.1.4.21.1.7 of next-hop ip address; The OID1.3.6.1.2.1.4.20.1.1 of interface IP address.
202, server receives title and the address information of the bearer network equipment that equipment in telecom network returns according to indication, and this address information comprises all next-hop address informations and the interface IP address information of the bearer network equipment that gathers;
For example, router-A among Fig. 3 receives SNMP and gathers after the indication, return title, next-hop address information (being IP5) and the interface IP address information (being IP3 and IP4) of router-A to equipment in telecom network A, equipment in telecom network A returns to server with these address informations again.
Whether all next-hop address informations that 203, receive in the server determining step 202 are all preserved, if the next-hop address information of not preserving is arranged, then execution in step 204, otherwise execution in step 205;
As shown in Figure 3, server is connected with equipment in telecom network A, equipment in telecom network B simultaneously, in this case, can only gather the information of router by equipment in telecom network A or equipment in telecom network B, also can gather simultaneously the information of router by equipment in telecom network A and equipment in telecom network B, in the present embodiment, set forth as an example of the former example.
As shown in Figure 3, server collects after the address information of router-A by equipment in telecom network A, whether all next-hop address informations (only having IP5 here) of the router-A that can receive by judgement are all preserved, if the next-hop address information of not preserving is arranged, then the specification interface address information comprises that the address information of the router B of the next-hop address information that this is not preserved does not also gather execution in step 204.
204, server is preserved title and the address information of the bearer network equipment that receives in the step 202, and to equipment in telecom network transmission collection indication, to gather title and the address information of bearer network equipment, the interface IP address information of the bearer network equipment that this need to gather comprises the next-hop address information of not preserving of judging in the step 203, and execution in step 202;
After the title and address information of collection of server end router A, obtain the next-hop address information IP5 of router-A, and judge that IP5 does not preserve, because IP5 is the interface IP address information of router B, title and address information that router B is described also do not gather, therefore, server continues to gather title and the address information of router B.As shown in Figure 3, gather title and the address information of router B, because the interface IP address information of router B comprises IP5, the SNMP in the step 201 be gathered IP3 among the IP 2 in the Indication message bag change IP5 into and get final product.
After the indication of the title that sends collection router B to equipment in telecom network and address information, server can receive title, next-hop address information (being IP7) and the interface IP address information (being IP5 and IP6) of router B, and judge that IP7 does not preserve, server is preserved title and the address information of router B, and to equipment in telecom network transmission collection indication, to gather title and the address information of bearer network equipment, this bearer network equipment is the bearer network equipment (being router C) that interface IP address information comprises IP7.
205, preserve title and the address information of the bearer network equipment that receives in the step 202, and trigger step 206;
After the indication of the title that sends collection router C to equipment in telecom network and address information, server can receive title, next-hop address information (being IP6) and the interface IP address information (being IP7 and IP8) of router C, and judge that IP6 preserves, all bearer network equipment are described, the title and the address information that are router-A, B, C all gather, preserve title and the address information of router C.
206, according to the title of equipment in telecom network and title and the interface IP address information of default gateway address information and bearer network equipment, determine the annexation between equipment in telecom network and the bearer network equipment;
As shown in Figure 3, server all is connected with equipment in telecom network A, equipment in telecom network B, and server preserves the default gateway address information of equipment in telecom network A, B, is respectively IP3 and IP8.After the title, next-hop address information and the interface IP address information that have gathered router-A, B, C, server can judge whether the default gateway address information of equipment in telecom network is the interface IP address information of router, if determine that then this router and this equipment in telecom network are direct-connected.For example, server is judged the default gateway address information of equipment in telecom network B, and namely IP8 is the interface IP address information of router C, determines that equipment in telecom network B and router C are direct-connected.
Can preserve the service address information of each equipment in telecom network on the server, in this case, step 205 specifically can comprise: send service path according to the service address information of equipment in telecom network corresponding to the 5th title to equipment in telecom network corresponding to the 6th title and detect request, to obtain the first address information of jumping from the service path of equipment in telecom network corresponding to equipment in telecom network to the five titles corresponding to the 6th title, the address information of the last two jump; If the interface IP address information of the bearer network equipment that the 7th title is corresponding comprises the first address information of jumping, determine that then this bearer network equipment equipment in telecom network corresponding with the 6th title is direct-connected; If the interface IP address information of the bearer network equipment that the 8th title is corresponding comprises the address information of the last two jump, determine that then this bearer network equipment equipment in telecom network corresponding with the 5th title is direct-connected.
The order of address information that defines each jumping of the service path from equipment in telecom network A to equipment in telecom network B herein is: as shown in Figure 3, the first address information of jumping is the interface IP address information IP3 with the direct-connected router-A of equipment in telecom network A, the second address information of jumping is the interface IP address information IP5 of router B, the 3rd address information of jumping is the interface IP address information IP7 of router C, the forth jump, the i.e. address information of final jump are the interface IP address information IP9 of equipment in telecom network B.
For example, if server is preserved the service address information of equipment in telecom network A, B among Fig. 3, be respectively IP2 and IP9.Server is after the title, next-hop address information and the interface IP address information that have gathered router-A, B, C by equipment in telecom network A, can send service path to equipment in telecom network A and detect request, carry IP9 in this request, to obtain the address information of each bar on the service path from equipment in telecom network A to equipment in telecom network B, be IP3, IP5, IP7, IP9, thereby obtain the address information (being IP3) of the jumping of first on this service path, the address information (being IP7) of the last two jump; Determine that interface IP address information comprises that router-A and the equipment in telecom network A of the first address information (being IP3) of jumping are direct-connected; Determine that interface IP address information comprises that router C and the equipment in telecom network B of address information (being IP7) of the last two jump is direct-connected.
Be understandable that step 205 can also adopt other implementation, for example the mode in the step 102 (2).
207, determine the annexation of bearer network equipment room according to title, next-hop address information and the interface IP address information of bearer network equipment;
As shown in Figure 3, server is after the title, next-hop address information and the interface IP address information that have gathered router-A, B, C by equipment in telecom network A, can judge that the next-hop address information IP5 of router-A is the interface IP address information of router B, determines that router-A and router B are direct-connected; Judge that the next-hop address information IP7 of router B is the interface IP address information of router C, determines that router B and router C are direct-connected.
Need to prove herein, also can not adopt the interface IP address information of bearer network equipment in the step 206,207, and other address information of employing bearer network equipment (for example, the physical address information of bearer network equipment, and the corresponding relation of the physical address information of preserving in the bearer network equipment and interface IP address information), therefore, can not gather the interface IP address information of bearer network equipment among the step 201-205, and gather other address information of bearer network equipment.
Need to prove herein, server can also obtain service path (service path refers to two paths between the equipment in telecom network) according to title and the address information of bearer network equipment and equipment in telecom network after the title and address information of having obtained all bearer network equipment from equipment in telecom network.
As shown in Figure 3, server is gathering router-A, B, after the title of C and the interface IP address information, can send service path to equipment in telecom network A according to the service address information IP9 of equipment in telecom network B and detect request, to obtain the address information of each jumping on the service path from equipment in telecom network A to equipment in telecom network B, be followed successively by IP3, IP5, IP7, IP9, because IP3, IP5, IP7 is respectively router-A, B, the interface IP address information of C, therefore, can determine that the service path from equipment in telecom network A to equipment in telecom network B passes through equipment in telecom network A successively, router-A, B, C, equipment in telecom network B.After the service path that obtains between the equipment in telecom network, unusual if the service path between the equipment in telecom network occurs, then can detect the unusual concrete equipment of appearance on the service path, delimit the time thereby shorten fault, reduce maintenance difficulties.
