Description
Technical Field
The invention relates to the field of network communication, in particular to a method for improving readability of BGP peer jitter alarm information in an IP network.
Background
The Border Gateway Protocol (BGP) is a routing Protocol for an autonomous system running on TCP. The BGP protocol is currently the only protocol used to handle internet-sized networks and is the only protocol that can properly handle multiple connections between unrelated routing domains, and is widely used across the global internet.
The jitter of a BGP protocol may be accompanied by the routing convergence of a large-scale data center and thousands of devices, so that it is always very important to monitor the state of the BGP protocol, and in almost all networks running the BGP protocol, the network monitoring system monitors the state of the BGP protocol, so that a network manager can sense whether the state of the BGP protocol changes at the first time. BGP jitter is usually given as alarm information of BGP peer state change (see fig. 1), such as an alarm reflecting which name and IP correspond device, when and which IP address correspond BGP peer state is changed from OPENCONFIRM to ESTABLISHED; the BGP state change alarm is a common alarm in the network, but the BGP state change alarm in the above example causes convergence of routes in the BGP network, because the back of the BGP generally means a large-scale cluster or data center, and one BGP peer jitter may affect over hundreds of servers or key services, and the impact is large, so a network manager needs to know this type of convergence in time.
In the existing scheme, the warning information of the BGP peer state change can only provide the following information: (1) the local terminal equipment name and equipment IP with BGP peer state change; (2) a target IP address (management IP of non-peer equipment) where a BGP peer state change occurs; (3) the changing process of the BGP peer state (i.e., from which state to which state); (4) point in time when a BGP peer state change occurs. However, in general, a device may have a plurality of BGP peers, which may be different devices, and since the state of a BGP peer changes, only the corresponding IP address of a specific peer is output, but the IP address usually does not have an obvious identifier, which device cannot be directly determined according to the IP address, at this time, a network manager cannot know which device has a changed peer state at the first time by visually reading alarm information, and needs to know and confirm the influence range of the current fault by experience or by logging in the device after receiving the BGP peer alarm information, so that when a device has a large number of BGP peers, after receiving a BGP jitter alarm, the manager needs to further confirm which device has a changed peer state by using the alarm information, the method not only consumes labor, but also causes a blank period for fault processing and information notification, and the application scene of the BGP protocol determines that the influence of the BGP protocol after the fault is wide, so that the blank period causes very bad influence on network service due to incapability of rapidly processing when a BGP peer jitter alarm occurs in a network applying the BGP protocol.

The method realizes the perfection of the alarm information, and enables the network management personnel to directly determine which BGP peer of the equipment is jittered in the alarm information received when the fault occurs, thereby timely knowing the influence surface of the fault, enabling the network management personnel to focus on shortening the fault recovery time instead of spending precious time to confirm the fault influence range, and further reducing the influence of BGP jitter on the network, which causes route convergence.
The embodiments of the present invention are described in further detail below.
The embodiment provides a method for improving the readability of BGP peer jitter alarm in an IP network, which can realize that when a BGP peer jitters, relevant information is inquired through dynamic linkage, and then BGP peer jitter alarm information which is convenient for network management personnel to visually read out which BGP peer of a device jitters is obtained.
Referring to fig. 2, the specific process of the method is as follows:
when the network operates normally, no BGP jitter alarm exists, and no equipment sends corresponding alarm information to the network management platform;
when the network is abnormal, such as a line fault or an opposite terminal equipment fault, the BGP jitter of the equipment is triggered, and at the moment, the equipment sends alarm information of the BGP jitter to the network management platform through a protocol channel between the equipment and the network management platform;
after receiving BGP jitter alarm information sent by equipment, a network management platform intercepts and captures the BGP jitter alarm information, formats the captured BGP jitter alarm information and unifies the BGP jitter alarm information into a consistent data structure, and the processing is mainly characterized in that the formats of the BGP jitter alarm information sent by the equipment of different manufacturers may be different, so that the BGP jitter alarm information sent by the equipment of different manufacturers is processed to enable the data structures of the BGP jitter alarm information to be unified in order to ensure subsequent processing;
preferably, the formatted BGP jitter alarm information has the same data structure, that is, as follows:
(A) the local terminal equipment name and equipment IP with BGP peer state change;
(B) a target IP address (management IP of non-peer equipment) where a BGP peer state change occurs;
(C) the changing process of the BGP peer state (i.e., from which state to which state);
(D) a point in time when a BGP peer state change occurs;
after the processing of step 2, extracting a target IP address with a BGP peer state change from the formatted BGP peer jitter alarm information, and inquiring in a pre-established dynamically updated network equipment interface IP and network equipment information association relation table by taking the target IP address with the BGP peer state change as an inquiry condition to obtain an opposite terminal equipment name and an equipment management IP with the IP address in the network;
step 4, backfilling the content of the warning information:
and (3) replacing the target IP address with the BGP peer state change in the BGP peer jitter alarm information by the opposite terminal equipment name obtained after the processing in the step (3), keeping other contents unchanged, and obtaining the BGP peer jitter alarm information after the replacement, namely the BGP peer jitter alarm information for improving the readability.
Further, the method further comprises the step 5: and pushing the BGP peer jitter alarm information for improving the readability to a notification medium.
The method is based on a pre-established network equipment interface IP and network equipment information association relation table, realizes that when BGP jitter alarm sends the alarm information to a network management platform from equipment triggering the event, the alarm event and the alarm information content thereof are automatically captured, and then the specific alarm information content reaches network management personnel after processes of formatting, table look-up, replacing, pushing to a notification medium and the like, thereby realizing the replacement of the original alarm content and achieving the purpose of improving the readability of the alarm information.
The pre-established dynamically updated network device interface IP and network device information association table used in step 3 of the method is to establish a dynamically collected and updated network device interface IP and network device information association table for all devices in the whole network, the table is established by dynamically obtaining a northbound API interface provided by the network device itself, the northbound interface of the device may be CLI/SNMP/NETCONF/REST API or the like, all interface IP information on each network device can be obtained by combining the interfaces and the one or more interfaces in a timing task or manual triggering manner, then the information is respectively associated with the device itself, and finally the network device interface IP and network device information association table is obtained by falling database persistent storage.
Specifically, the way of the pre-established association table of the dynamically updated network device interface IP and the network device information is as follows: the method comprises the following steps:
the device information table is exemplified as follows:
"node_ip":"10.254.13.143"；
"login_method":"snmp"；
"login_key":"Snmp_Key_123"；
after the interface of the device and the IP on the interface are collected in step 31, because the data formats obtained by different northbound interfaces are different, the formatting operation is performed uniformly in order to facilitate subsequent data processing, and the purpose of formatting is to make the table entry structures finally obtained by all devices consistent.
after the formatting operation, the storage can be performed according to a unified structure, and a final network device interface IP and network device information association table is formed, where an example of the table structure is as follows:
"log_time":"2020-06-12 05:30:05",
"node_hostname":"B3.IAAS.RT.LF.H01",
"node_ip":"10.254.13.143",
"interface":"10GE1/0/16",
"ip_address":"192.168.1.254",
this example shows: on a device with system name b3.iaas. rt. lf. h01, management IP 10.254.13.154, there is an interface 10GE1/0/16 with IP 192.168.1.254 on the interface.
According to the method for pre-establishing the network equipment interface IP and network equipment information association relation table, all interfaces of the whole network equipment and IP information on the interfaces are associated with the current network equipment in a mode of combining periodicity and event triggering, and the method is convenient to use in perfecting alarm information processing.
The following shows the difference between the prior art scheme and the BGP peer jitter short message alarm information improved by the method of the present invention, taking BGP jitter alarm pushed to the short message platform as an example, see table 1:
TABLE 1 BGP Peer jitter SMS alarm information comparison before and after improvement
The comparison shows that the BGP peer jitter short message alarm information obtained by the method has better readability, and can be convenient for network management personnel to visually read which equipment has jitter faults.
Fig. 4 illustrates the state of the BGP jitter alarm information obtained by the method of the present invention corresponding to the network device, from which it can be seen that the alarm information obtained by the method of the present invention carries a specific name of the opposite end device, and the device name is as the same as the name of the user in life, which has a visual identification meaning, so that the network manager can know the device information at both ends of the peer jitter very visually, and the IP of the opposite end device in the original alarm information given by the prior art is as the personal identity number in life, although it is accurate and unique, but it is not visual for the network manager, and it cannot read out the specific network device visually, which affects the range of quickly determining the influence of the network fault.
The method of the invention replaces the original warning information with poor readability by checking the incidence relation table, improves the readability of BGP jitter warning content, ensures that network management personnel can confirm the specific fault peer equipment information after directly checking the warning information after BGP peers in the network are jittered, can immediately intervene to carry out fault recovery work, can know which specific peer is faulted without inquiring on the equipment for one time, and thus concentrates on fault recovery, shortens the fault processing time, eliminates the blank period of faults, improves the sustainable working time and the operation and maintenance efficiency of services, and reduces the cost of secondary inquiry and confirmation of operation and maintenance personnel.
Those of ordinary skill in the art will understand that: all or part of the processes in the method according to the embodiments of the present invention may be implemented by a program that can be stored in a computer-readable storage medium and that, when executed, can include the processes according to the embodiments of the methods described above. The storage medium may be a magnetic disk, an optical disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), or the like.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
