Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In an embodiment of the present invention, a method for monitoring an ip ran network loop is provided, as shown in fig. 1, the method includes:
step 102: configuring a convergence device to form a convergence device pair, and hanging an access device under the convergence device pair;
step 104: collecting port information of convergence equipment and access equipment;
step 106: based on the port information, obtaining a loop formed by the convergence equipment pair and the access equipment;
step 108: analyzing the port information to generate loop health state information, wherein the loop health state information comprises loop fault information;
step 110: and counting the looping rate according to different statistical dimensions based on the loop health state information.
In the embodiment of the present invention, step 102 is specifically executed as follows:
(1) first, appointing: the convergence device is represented by Bn, wherein n is a natural number, such as B1, B2 and the like; the access device is represented by Am, and m is a natural number, such as A1, A2 and the like. Configuring convergence B equipment to form a BB pair (two B equipment are directly connected to form a convergence layer, an OSPF protocol is adopted between the two B equipment, and the OSPF protocol is generally defaulted to area0), and an access A equipment is hung under the BB pair. OSPF (Open short path first, Open Shortest path first) is an Interior Gateway Protocol (IGP) used for routing decision in a single Autonomous System (AS). The method is an implementation of a link state routing protocol, which belongs to an Interior Gateway Protocol (IGP), and therefore operates in an autonomous system. The OSPF routing protocol is a typical Link-state (Link-state) routing protocol, and is generally used in the same routing domain.
(2) Setting a trap log information sending address of the B device as a system server S, and receiving and converging an on-line trap log on the access device triggered and sent by the B device when the access A device is powered on;
(3) analyzing the online trap log of the access A equipment to obtain the topology parameters of the access A equipment;
(4) and generating corresponding configuration information according to the topology parameters of the access A equipment (namely, calling a corresponding management instruction set by the system server S for configuration and issuing), and issuing the configuration information to the access equipment for configuration so that the access A equipment can manage.
In the embodiment of the present invention, step 104 specifically includes:
collecting port information of convergence equipment and access equipment through an SNMP (simple network management protocol);
the port information includes: one or more of ingress rate, egress rate, port bandwidth, remote device ip, remote device port, port physical state, port subinterface (31 is used by the invention) OSPF state.
In this embodiment of the present invention, step 106 specifically includes:
obtaining the relationship between the convergence equipment and the access equipment, and the relationship between the access equipment and the access equipment according to the far-end equipment ip and the far-end equipment port;
and obtaining a loop formed by the convergence device pair and the access device based on the relationship between the convergence device and the access device and the relationship between the access device and the access device.
For example, sink device B1 port 1/1 is physically linked directly to remote device a1 port 1/2 (from the ip-associated device table of remote device a 1) resulting in a B1(1/1) -a 1(1/2) relationship. A1-A2, A2-An, An-B2, in this way, a complete loop B1-A1-A2-An-B2 is obtained.
Specifically, the device B can automatically receive a trap log on the device, and the system server S can obtain a neip address (neighbor address) of the new on-line device a by analyzing the log; then logging in the new device from the device B, and executing to view lldp (Link layer Discovery Protocol) information to obtain a device association relation and a port relation, so as to obtain topology data relation information; acquiring neighbor neip information, neighbor home end port information and neighbor opposite end port information through snmp according to the availability of left and right devices of the new device, and further acquiring topological relation data information; according to the neighbor analysis result, the program automatically and recursively presents a BB pair complete topology data information, and displays the program through the client topology, as shown in fig. 2.
In an embodiment of the present invention, the fault model includes: congestion faults, interruption faults, false ring faults.
The congestion fault is: the flow of the interconnection port of the ring network element equipment exceeds 80 percent of the bandwidth.
The interrupt failure means: and (4) a down fault of the interconnection port of the ring network element equipment.
The false ring failure is: and the OSpf protocol of the interconnection port of the ring network element equipment fails.
(1) Step 108 specifically includes: determining inflow occupancy rate according to the inflow rate and the port bandwidth, comparing the inflow occupancy rate with an inflow occupancy rate threshold value, and determining whether congestion faults exist according to a comparison result; or, determining the outflow occupancy rate according to the outflow rate and the port bandwidth, comparing the outflow occupancy rate with the outflow occupancy rate threshold value, and determining whether congestion faults exist according to the comparison result.
And (3) detecting a congestion fault: based on the inspection port flow rate + predetermined threshold mode, the detection criteria are: a port flow rate exceeding 80% of the port bandwidth is abnormal.
For example, the ingress and egress traffic of the B1 device 1/1 port is divided by the port bandwidth to obtain ingress occupancy B1_ inR and egress occupancy B1_ outR, respectively, and B1_ inR and B1_ outR are compared with the congestion threshold, and if the congestion threshold is exceeded, an alarm color is displayed. A1-A2, A2-An, An-B2.
(2) Step 108 specifically includes: determining whether an interrupt fault exists between the convergence equipment and the access equipment according to the port physical state of the convergence equipment and the port physical state of the access equipment; or, determining whether an interrupt fault exists between the access equipment and the access equipment according to the port physical states of different access equipment.
And (3) interrupt fault detection: based on the LLDP state check and the predetermined threshold mode, the detection criteria are: the neighbor state shows that the neighbor ip is 0.0.0.0 as abnormal.
LLDP (Link Layer Discovery Protocol) is generated under such a background, and provides a standard Link Layer Discovery manner, which can organize information such as main capability, Management address, device identifier, interface identifier, etc. of a local device into different TLVs (Type/Length/Value), encapsulate the TLVs into LLDPDU (Link Layer Discovery Protocol Data Unit) and distribute the information to neighbors directly connected to the neighbor, and store the information in a form of standard MIB (Management information base) after the neighbor receives the information, so as to allow a network Management system to query and determine a communication status of a Link.
Under normal network conditions, for example, in the lldp information of the a1 device port P1, the remote port displays P2, and the management address displays the remote device a2 directly connected to P1 to manage ip. If port P2 has down fault, the management address displayed in the lldp information of port P of the a network element will be displayed as 0.0.0.0. The present invention judges that a fault has occurred between a1 and a2 based on this situation.
For example, according to the physical state of the 1/1 port of the B1 device and the physical state of the 1/2 port of the a1 device, as long as one of the satisfaction is down, an interrupt fault is indicated. All access a devices on the ring are identified as not being in the ring. A1-A2, A2-An, An-B2.
(3) Step 108 specifically includes: determining whether a false ring fault exists according to the OSPF state of the port subinterface of the convergence device and the OSPF state of the port subinterface of the access device; or, determining whether a false ring fault exists according to port sub-interface OSPF states of different access devices.
The detection standard is realized by checking OSPF neighbor state, and is as follows: the OSPF state is not Full, and its corresponding port protocol up is abnormal, as shown in FIG. 3.
The false ring detection probe simultaneously monitors port flows and port states of all mounted equipment A and port subinterfaces (31 used in the invention) OSPF process states of the BB pairs and B1 and B2 through distributed multithreading, and data information is quickly and efficiently processed through a memory database redis to obtain related congestion, interruption and false ring results of each ring of the BB pairs.
For example, according to the 1/1 port subinterface (31 used in the present invention) OSPF state of the B1 device and the 1/2 port subinterface (31 used in the present invention) OSPF state of the a1 device, a false ring failure is indicated as long as one of the satisfied conditions is not full. All access a devices on the ring are identified as fake rings. A1-A2, A2-An, An-B2.
In addition, other fault detection is provided as follows:
(1) BFD pseudowire detection
According to data configuration, routing protocol and port state detection BFD (Binary File Descriptor) pseudo wires. The detection standard is as follows: the BFD pseudowire state is DOWN.
The BFD for LDP LSP refers to establishing a BFD session on an LSP link and binding the session with BFD. And (4) rapidly detecting the LSP link failure by using BFD (bidirectional forwarding detection), and triggering the flow switching of the LSP. In a network configured with LDP fast reroute functionality, the LDP fast reroute functionality will fast switch traffic onto a backup LDP LSP when an interface fails (the interface will sense or incorporate BFD detection) or the primary LSP is not up (incorporate BFD detection). The protection of the main LSP is realized, the flow interruption time is ensured to be less than a certain time (the requirement of a telecommunication operator is generally 50ms), and the switching within the required time limit is realized.
(2) Error code switching fault detection
In a scenario where an IPRAN is used to carry a broadband service, a line error may cause a serious problem such as a base station stopping service or reducing a service level, and under the existing detection mechanism, an error event cannot trigger protection switching of a network. In order to solve the above problems, the error code switching function can be configured, so that the error code event triggers the network protection switching, and the influence of the error code on the service is reduced as much as possible.
After the function IS configured, if the error rate detected by the interface exceeds the configured threshold, the quality grade of the link IS changed into LOW, and a routing protocol (OSPF, IS-IS) IS triggered to adjust the cost value of the route, so that the route with a lower error rate IS selected. Therefore, the LDP LSP can be successfully established all the time, and a link with a smaller error rate is selected, so that the influence of error codes on services is reduced as much as possible.
The invention detects the mode of port error code rate + predetermined threshold value, and the detection standard is as follows: and detecting a port error code rate value according to a scheduling strategy, comparing the port error code rate value with a preset threshold value, and if the port error code rate value exceeds the preset threshold value, judging that the port error code rate value is abnormal.
