PTN services are divided into three layers: tunnel, pseudo wire, service, wherein, a tunnel can bear many pseudo wires, can bear many services in a pseudo wire.
In the invention, the network management system obtains and analyzes all service attribute information in each PTN network element under the management of the network management system to obtain the topology information of the tunnel (including the pseudo wire borne by the tunnel, the service borne by the pseudo wire and the like), so that when a user performs topology query on the tunnel, the pseudo wire or the service, the relationship among the three layers of the tunnel, the pseudo wire and the service can be visually displayed.
It should be noted that, in the present application, the network element and the PTN network element have the same meaning.
Referring to fig. 1, fig. 1 is a flowchart of a topology display method according to an embodiment of the present invention, which is applied to a network management system, and as shown in fig. 1, the method mainly includes the following steps:
step 101, acquiring all service attribute information in each PTN network element under management of a network management system, and determining topology information corresponding to a tunnel established between any two PTN network elements according to all the service attribute information.
In the existing implementation, each network element bearing the PTN service stores a segment of topology of the PTN service, which is described by service attribute information, and specifically includes: the network element information, the bearer information for service transmission, and the specific service information, etc. Wherein,
the network element information comprises the equipment type, the network element name and the like of the network element; the bearer information includes tunnel information and pseudowire information, wherein the pseudowire bears the PTN service, and the tunnel bears the pseudowire. The tunnel information includes tunnel identification and interface information, etc., the interface information is the corresponding interface of the network element in the tunnel, when the network element is the equipment at both ends of the tunnel, only one interface is included, and when the network element is the equipment in the middle of the tunnel, two interfaces are included, etc. The pseudowire information includes pseudowire identification and label information (including in-label and out-label), among others.
The network management system can actively send a request to each PTN network element under management so as to obtain all service attribute information in each PTN network element, and each PTN network element can actively report all the service attribute information of the network management system.
The network management system can determine the topology information of any tunnel by using all the acquired service attribute information of each PTN network element. In this embodiment, the method for determining topology information corresponding to a tunnel established between any two PTN network elements according to all the service attribute information specifically includes the following steps:
finding out all service attribute information with the same tunnel identifier, and recording as a set;
determining all PTN network elements through which the tunnel passes and interface information of the tunnel in each PTN network element according to the network element information and the interface information in each service attribute information in the set, and determining the connection relation between all PTN network elements through which the tunnel passes according to the label information of each service attribute information;
and determining all pseudo wires borne by the tunnels represented by the same tunnel identifier according to pseudo wire information in the service attribute information in the set, and determining all services borne by each pseudo wire based on the pseudo wire identifiers.
The following description is made with reference to fig. 2 as an example:
referring to fig. 2, fig. 2 is a schematic diagram of PTN networking in the implementation of the present invention, which includes a network element A, P, Z, where a tunnel 1 (not shown, but described as the standard) through a network element P and a tunnel 2 (not shown, but described as the standard) through a network element D are established between a network element a and a network element C, where the tunnel 2 is a protection tunnel of the tunnel 1, the tunnel 1 carries a plurality of pseudo wires, and taking the PTN service 1 carried on one of the pseudo wires as an example, service attribute information of the PTN service 1 exists in a network element A, P, Z, where,
in the network element a, the service attribute information of the PTN service 1 has the following contents: network element information (network element name NE 1); the bearer information includes tunnel information (tunnel identification: TE # 1; interface: if # 12; label information corresponding to if # 12: out-label P1 and in-label P4) and pseudowire information (pseudowire identification: PW # 1). In addition, since tunnel 1 also has a corresponding protection tunnel: tunnel 2, therefore, the tunnel information of the service attribute information may further include protection tunnel information (tunnel identifier: TE # 2; interface if # 14; label information corresponding to if # 14: out-label P5 and in-label P8);
in the network element P, the service attribute information of the PTN service 1 has the following contents: network element information (network element name NE 2); the bearer information includes tunnel information (tunnel id: TE # 1; interface on the side of connecting network element a: if #21, tag information corresponding to if # 21: out-tag P4 and in-tag P1, and interface on the side of connecting network element Z: if #23, tag information corresponding to if # 23: out-tag P2 and in-tag P3). Since the network element P is a tunnel middleware, there is no pseudo wire information.
The network element D is used as a device through which a protection tunnel passes, and the service attribute information of the PTN service 1 has the following contents: the service attribute information includes: in addition, network element information (network element name is NE 4); the bearer information includes tunnel information (tunnel id: TE # 2; interface: interface if #41 on the side of the connection network element a, label information corresponding to if # 41: out-label P8 and in-label P5; interface if #43 on the side of the connection network element Z, label information corresponding to if # 43: out-label P6 and in-label P7). Since the network element D is a protection tunnel intermediate device, there is no pseudo wire information.
In the network element Z, the service attribute information of the PTN service 1 has the following contents: network element information (network element name NE 3); the bearer information includes tunnel information (tunnel identification: TE # 1; interface: if #32, label information corresponding to if # 32: out-label P3 and in-label P2) and pseudowire information (pseudowire identification: PW # 1). In addition, since tunnel 1 also has a corresponding protection tunnel: tunnel 2, therefore, the tunnel information of the service attribute information may further include protection tunnel information (tunnel identifier: TE # 2; interface if #32, label information corresponding to if # 32: out label P7 and in label P6).
After the network management system obtains all the service attribute information of each PTN network element, determining the topology information of a tunnel according to the following steps:
firstly, all service attribute information with a tunnel identifier of TE #1 is found, and the service attribute information with the tunnel identifier of TE #1 is recorded as a set;
then, determining, according to the network element information in each service attribute information in the set, that the PTN network element through which the tunnel with the tunnel identifier TE #1 passes includes: network element A, network element P, and network element Z; determining that the tunnel with the tunnel identifier TE #1 has an interface on the network element A according to the interface information of each service attribute information in the set: if #12, there are two interfaces if #21 and if #23 on net element P, and one interface if #32 on net element Z; according to the label information in the service attribute information in the set, the following steps can be determined: interface if #12 at network element a is connected to interface if #21 at network element P and interface if #23 at network element P is connected to interface if #32 at network element Z. To this end, the tunnel identified as TE #1 is known to pass through network element A, P, Z and the connection relationship is A-P-Z.
Finally, according to the pseudowire identifier in the service attribute information in the set, it can be determined that the pseudowire PW #1 is carried in the tunnel with the tunnel identifier TE #1, and the PTN service 1 is carried in the pseudowire PW # 1.
Based on the same procedure as described above, it can be determined that the tunnel identified as TE #21 passes through the network element A, D, Z and the connection relationship is a-D-Z. In addition, pseudowires carried in the tunnel with the tunnel identification TE #21 can also be determined, and PTN traffic carried in the pseudowires.
And 102, when receiving a topology display request, performing topology display based on the topology display request according to topology information corresponding to a tunnel established between any two PTN network elements.
In practical application, a user can perform topology query on a tunnel layer, perform topology query on a pseudo wire layer, and perform service query on a service layer.
When a user needs to perform topology query at a tunnel level, a topology display request for a certain tunnel may be sent, and in this case, the specific steps of performing topology display based on the topology display request according to topology information corresponding to a tunnel established between any two PTN network elements are as follows:

then, searching the topology information of the tunnel, and determining all PTN network elements through which the tunnel passes, interface information of the tunnel in each PTN network element, connection relations among all PTN network elements through which the tunnel passes, and all pseudo wires borne by the tunnel according to the topology information of the tunnel;
then, sequentially outputting topology display information corresponding to each PTN network element passed by the tunnel according to the connection relation among all PTN network elements passed by the tunnel; the topology display information corresponding to each PTN network element comprises: the network element name of the PTN network element, the interface information of the tunnel in the PTN network element and the tunnel identifier.
Finally, because a plurality of pseudowires are carried in the tunnel, all pseudowire information carried by the tunnel can be output to a user in a list or other forms.
Taking tunnel 1 with tunnel identifier TE #1 in fig. 2 as an example, when a user sends a topology display request for tunnel 1, the finally output topology map (in which the outgoing label and the incoming label are not specifically drawn) may be specifically as shown in fig. 3.
When a user needs to perform topology query on a pseudowire layer, a topology display request for a pseudowire can be sent, and in this case, the specific steps of performing topology display based on the topology display request according to topology information corresponding to a tunnel established between any two PTN network elements are as follows:
firstly, determining a pseudo wire for which a topology display request aims, and determining a tunnel for bearing the pseudo wire;
then, searching the topology information of the tunnel, and determining all PTN network elements through which the tunnel passes, interface information of the tunnel in each PTN network element, connection relations among all PTN network elements through which the tunnel passes, and all services borne by the pseudo wire according to the topology information of the tunnel;
then, sequentially outputting topology display information corresponding to each PTN network element passed by the tunnel according to the connection relation among all PTN network elements passed by the tunnel; the topology display information corresponding to each PTN network element comprises: the network element name of the PTN network element, the interface information of the tunnel in the PTN network element, the tunnel identifier and the pseudo wire identifier;
finally, since the pseudowire can carry a plurality of services, all the service information carried by the pseudowire can be output to the user in a list or other forms.
Taking the pseudowire PW #1 carried by tunnel 1 with the tunnel identifier TE #1 in fig. 2 as an example, when a user sends a topology display request for PW #1, a finally output topology map (in which an outgoing label and an incoming label are not specifically drawn) may be specifically as shown in fig. 4.
When a user needs to perform topology query on a service level, a topology display request for a certain service may be sent, and in this case, the specific steps of performing topology display based on the topology display request according to topology information corresponding to a tunnel established between any two PTN network elements are as follows:
firstly, determining a service for which a topology display request is directed, and determining a pseudo wire bearing the service and a tunnel bearing the pseudo wire;
then, searching the topology information of the tunnel, and determining the connection relationship among all PTN network elements through which the tunnel passes, the interface information of the tunnel in each PTN network element and all PTN network elements through which the tunnel passes according to the topology information of the tunnel;
then, sequentially outputting topology display information corresponding to each PTN network element passed by the tunnel according to the connection relation among all PTN network elements passed by the tunnel; the topology display information corresponding to each PTN network element comprises: the network element name of the PTN network element, the interface information of the tunnel in the PTN network element, the tunnel identifier, the pseudo wire identifier and the service information;
