Detailed Description
The invention will be described in detail with reference to the following drawings and examples, it being understood that the preferred examples are set forth to illustrate and explain the invention, and are not to be construed as limiting the invention.
Example one
Fig. 1 is a flowchart of a service alarm processing method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
step S102, setting a source object and a destination object of multicast service of a three-layer virtual private network L3VPN configured on a network element, wherein the network element is bridged over a first network and the L3VPN network, and the source object and the destination object are respectively connected with the first network and the L3VPN network;
step S104, establishing an alarm mapping relation between the source object and the destination object;
step S106, the alarm mapping relation is sent to the equipment corresponding to the network element.
The steps S102 and S104 are configuration operations on the network manager, and the step S106 is to use the device corresponding to the configured information issued on the network manager for establishing the actual mapping relationship.
Under the condition that the first network is a third-party network, the source object is an input interface on a network element and is connected with the third-party network, and the destination object is an output interface on the network element and is connected with the L3VPN network; and under the condition that the first network is the L2VPN network, the source object is an output interface on the network element and is connected with the L3VPN network, and the destination object is a pseudo wire on the network element and is connected with the L3VPN network and the L2VPN network.
By the method, once the network connection fails and transmission link switching is required, and the connection between the main and standby network elements fails, so that the network on the other side cannot know the failure, the failure message can be transmitted to the network on the other side by establishing the mapping relation of the source and destination objects, so as to realize subsequent operations of switching the main and standby transmission links and the like.
Further, setting the source object and the destination object of the multicast service of the L3VPN configured on the network element includes: setting a virtual private network route forwarding VRF as a multicast VRF, and inquiring an access port of the multicast service according to the multicast VRF; setting the node type of the network element according to the access port; and setting the source object and the sink object according to the node type.
Further, setting the node type of the network element according to the access port includes: when the access port does not comprise a virtual Ethernet type interface, setting the node type of the network element as a three-layer core ground node; and when the access port comprises the interface of the virtual Ethernet type, setting the node type of the network element as a bridging node.
Further, setting the source object and the sink object according to the node type includes: when the node type is the three-layer core ground node, acquiring an input interface of static multicast configuration information of the multicast service according to the multicast VRF, and setting the source object as the input interface; acquiring an output interface of the static multicast configuration information according to the multicast VRF, and setting the host object as the output interface;
when the node type is the bridge node, acquiring an output interface of multicast routing configuration information of the multicast service according to the multicast VRF, and setting the source object as the output interface; and acquiring the pseudo wire of the L2VPN according to the access port of the multicast service and the service association relationship between the L3VPN and the L2VPN, and setting the host object as the pseudo wire.
Further, establishing the alarm mapping relationship between the source object and the sink object includes:
acquiring a detection session of the source object, and generating a source tracking detection group according to the detection session; adding the source object into the source tracking detection group, and binding the host object and the source tracking detection group to generate a corresponding binding relationship; judging whether the tunnel of the source object and the tunnel or the pseudo wire of the destination object have the configuration of multi-protocol label switching transmission application operation, management and maintenance (MPLS-TP-OAM); and under the condition that the configuration exists, establishing the alarm mapping relation between the source object and the destination object according to the binding relation.
Further, obtaining the detection session of the source object includes: when the node type is the three-layer core ground node, setting a three-layer Ethernet interface or a three-layer aggregation port according to the access interface; acquiring a detection session of the source object according to the three-layer Ethernet interface or the three-layer aggregation port, wherein the detection session is an interface type detection session; when the node type is the bridge node, acquiring the tunnel information of the network element according to the output interface; and acquiring the detection session of the source object according to the tunnel information, wherein the detection session is a multicast tunnel type detection session.
The detection session is a detection means, and whether the source object can normally communicate or not and whether the sink object can normally communicate or not can be judged by acquiring information of the detection session.
The detection session of the source object carries the information of the source object, and adding the source object into the source tracking detection group is represented as adding the detection session of the source object into the source tracking detection group in the actual operation. The binding of the host object and the source tracking detection group is indirectly the binding of the host object and the source object. The binding strategy can be that after all source objects in the source tracking detection group are invalid, the bound host object starts working; or the bound host object starts working after the source tracking detects that part of the source objects in the group fail.
All source objects can be set to be added into the source tracking detection group, and all the destination objects are bound with the source tracking detection group; or selecting a part of source objects to be added into the source tracking detection group, and binding a part of host objects with the source tracking detection group. The tracking detection group may be an existing detection group in the queried network element, or a detection group set and generated by the network manager.
Further, obtaining the detection session of the source object includes: when the node type is the three-layer core ground node, setting a three-layer Ethernet interface or a three-layer aggregation port according to the access interface; acquiring a detection session of the source object according to the three-layer Ethernet interface or the three-layer aggregation port, wherein the detection session is an interface type detection session; when the node type is the bridge node, acquiring the tunnel information of the network element according to the output interface; and acquiring the detection session of the source object according to the tunnel information, wherein the detection session is a multicast tunnel type detection session.
Further, setting the three-layer ethernet interface or the three-layer aggregation port according to the ingress interface includes:
when the input interface comprises an Ethernet interface or an aggregation port, maintaining the Ethernet interface or the aggregation port unchanged; when the incoming interface includes an ethernet subinterface or an aggregation subport, the ethernet subinterface or the aggregation subport is converted into a corresponding ethernet interface or an aggregation port.
Through the operation, the same incoming interface can be filtered, and the same incoming interface is prevented from creating the same detection session, so that the detection session is redundant.
Further, determining whether the MPLS-TP-OAM configuration exists between the tunnel of the source object and the tunnel or the pseudo wire of the destination object includes: when the node type is the three-layer core landing node, judging whether the tunnel of the host object has the configuration of the MPLS-TP-OAM; and when the node type is the bridge node, judging whether the MPLS-TP-OAM configuration exists between the tunnel of the source object and the pseudo wire of the destination object.
When the node type is the three-layer core ground node, if the source object, that is, the ingress interface of the network element further includes a tunnel interface, it needs to determine whether the tunnel corresponding to the source object has the configuration of the MPLS-TP-OAM.
Further, before determining whether the MPLS-TP-OAM configuration exists between the tunnel of the source object and the tunnel and the pseudowire of the destination object, the method further includes: when the node type is the three-layer core ground node, acquiring the configuration information of the tunnel corresponding to the host object; when the node type is the bridge node, acquiring the configuration information of the tunnel corresponding to the source object; and acquiring the configuration information of the pseudo wire according to the host object.
Wherein the tunnel is a point-to-multipoint P2MP tunnel.
Further, after sending the alarm mapping relationship to the device corresponding to the network element, the method further includes:
and under the condition that the detection session of the source object fails, setting the continuity and connectivity detection message which is configured in the MPLS-TP-OAM of the host object and stops sending as enabled, and transmitting fault messages according to the alarm mapping relation.
Through the steps, once the network fails and the connection between the main network element and the standby network element fails, the opposite end network connected with the host object knows that the network connected with the source object fails and needs to carry out service switching by setting the host object
Further, when the node type is the three-layer core landing node, the ingress interface of the network element includes an ethernet interface, an ethernet subinterface, an aggregation port or an aggregation subinterface, or a P2MP tunnel interface, the egress interface is a P2MP tunnel interface, and the first network is a third-party network; when the node type is the bridge node, the outgoing interface of the network element is the P2MP tunnel interface, and the first network is an L2VPN network.
