The sequence of steps involved in the embodiments is for illustrative purposes to illustrate the implementation of the present application, and the sequence of steps is not limited and can be adjusted as needed.
An embodiment of the present invention provides a method for monitoring routing information, and fig. 1 is a flowchart of a method for monitoring routing information provided in an embodiment of the present invention, and as shown in fig. 1, the method may include the following steps:
s101, route information of each routing device in the data network is periodically collected and stored as a corresponding route snapshot file.
It should be noted that the data network in the embodiment of the present invention may be, but is not limited to, a core network, a bearer network, and the like.
Optionally, the embodiment of the present invention may log in each routing device in the data network periodically in a manner of a command line, collect routing information of each routing device, and store the routing information as a corresponding routing snapshot file.
And S102, comparing the next hop network addresses corresponding to the same target network segment according to the route snapshot files of two adjacent periods.
Since the routing information includes the destination IP address, when comparing the two-cycle route snapshot files, it is only necessary to compare whether the next-hop network address (i.e., the next-hop IP address) corresponding to the same destination network segment changes.
S103, determining the route change information of each routing device in the data network according to the comparison result.
In an optional implementation manner, in the above S103, new, reduced, or modified route change information in the data network may be determined according to a comparison result of the route information of all the routing devices in two adjacent cycles.
In another alternative embodiment, in the above S103, the route change information of the single routing device may be determined according to a comparison result of the route information of the single routing device in two adjacent cycles.
And S104, outputting the route change information of each routing device in the data network.
It should be noted that, for different requirements of a scenario, the route change information of each routing device in the data network may be output in multiple ways, for example, the route change information may be the total route change information of the data network, or the route change information of a single routing device in the data network.
As an alternative implementation, the S104 may include the following steps: receiving a route query instruction, wherein the route query instruction is used for specifying any one of the following query conditions: data network information, routing equipment information, routing change types and comparison time; and outputting the route change information of each routing device in the data network according to the route query instruction.
As can be seen from the above, the method for monitoring routing information provided in the embodiment of the present invention can compare the next-hop network addresses corresponding to the same destination network segment according to the routing snapshot files in two adjacent periods by periodically acquiring the routing information of each routing device in the data network and storing the routing information as the corresponding routing snapshot file, so as to determine the routing change information of each routing device in the data network according to the comparison result, and finally output the routing change information of each routing device in the data network.
The method for monitoring the routing information provided by the embodiment of the invention monitors the routing change information of each routing device in the data network based on the routing information snapshot file which is periodically acquired and stored, does not need to deploy the routing receiving device which specially acquires the routing information, and can greatly reduce the equipment investment cost.
In an optional embodiment, the method for monitoring routing information provided in the embodiment of the present invention may further include the following steps: collecting the routing information of each routing device at the current moment, and storing the routing information as a corresponding routing snapshot file; obtaining a route snapshot file of each routing device at the same historical time; comparing a target network segment and a next hop network address corresponding to each routing device at two moments according to the routing snapshot file of each routing device at the current moment and the same historical moment; determining real-time routing change information of each routing device in the data network according to the comparison result; and outputting the real-time route change information of each routing device in the data network. By the embodiment, the routing information of each routing device in the data network is monitored in real time.
The following describes embodiments of the present invention in detail by taking a core network and a bearer network as examples.
Because many routing devices are in the data network, in the specific implementation process, for a core network (CMNET) and a bearer network, the concerned routing information can be combed by taking a service as a unit, the concerned routing information is periodically collected (for example, by taking one hour as a unit), and is stored in a storage as a routing snapshot, the latest routing snapshot is compared with the routing snapshot collected and stored in the previous storage, whether a new, reduced or changed routing device exists or not is judged, and the related information of the specific new, reduced or changed routing device can be output. Optionally, manual intervention may be supported for the key monitoring routes, requiring manual confirmation of the process and recording of the corresponding process personnel.

The first difference case: the route changes.
The next IP address of the segment of the routing table today is compared with the next IP address of the segment of the routing table yesterday. That is, NextHop for today's routing table Destination/Mask is compared to NextHop for yesterday routing table Destination/Mask, and if there is a change in NextHop (the number of Nexthop addresses to the same Destination segment is reduced or changed), then the route is considered changed. FIG. 9 illustrates a situation where the number of next hop addresses for the same destination network segment is reduced; fig. 10 shows a schematic diagram of routing information with changed next hop addresses of the same destination network segment.

The comparison is made by daily stored routes, such as yesterday's route table versus today's route table. During comparison, only the difference comparison of the Network information and the Next Hop information in the routing table is needed.
The first difference case: route change
Next Hop of today's routing table network is compared with Next Hop of yesterday's routing table network, and if the Next Hop address changes, the route is considered to have changed. Fig. 15 shows a situation where the next hop address of the same destination network segment changes.
The second difference case: route loss
Comparing the network segment under the yesterday routing table network with the network segment of the network today, finding that the network segment of the network today is lost, and considering that the route is changed at the moment.

Tables 1 to 3 show the structure of the relevant tables, and table 1 shows the device full routing table (DevRouteInfo table); table 2 shows a device route change table (DevRouteChangeH table) at hour granularity; table 3 shows an immediate acquisition device route change table (DevRouteChangeIM table).
Table 1 device full routing table (DevRouteInfo table)
TABLE 2 hours granularity Equipment routing Change Table (DevRouteChangeH Table)
For the route snapshot comparison of hour granularity, the collection processing logic is as follows:
for example, route collection is performed once for a device (bearer network, CMNET) at an interval of one hour (time point is normalized to hour) (because the route collection command is single but output time is long, concurrent execution can be considered, and the number of concurrent execution is according to actual conditions), and route comparison is performed by taking a single unit as a unit (following a previous hour result, the previous hour result is obtained from a DevRouteInfo table, and a corresponding device value of the previous day is obtained), and if the comparison result is found to be increased or decreased, data is inserted into the DevRouteChangeH table (state 1). And finally updates the DevRouteInfo table into the current result (acquisition time is normalized to the current hour).
Special case processing:
firstly, if the device has no data in the previous hour, the DevRouteInfo is directly updated without comparison.
Supporting multiple executions within one hour, comparing the current hour, and entering data after the data of the current hour are cleared by the DevRouteInfo and the DevRouteChangeH.
③ the full scale table reserves seven days data at most, deletes seven days before DevRouteInfo information, the change table reserves one month data
And fourthly, adding, reducing and modifying the change types. The modification is that the route is not changed but the corresponding next hop is changed (the new and the next hop are reduced).
Judging the professional and city information according to the node where the equipment is located.
Table 3 instant acquisition device route change table (DevRouteChangeIM table)
For the instant route acquisition comparison, the acquisition processing logic is as follows:
acquiring according to needs, receiving the scheduling parameters of the foreground: the time of acquisition (to the nearest second) device ID, the route information from the device instant login device was acquired and compared to this device route information at 22:00 yesterday. The comparison result information is input into a DevRouteChangeIM table, the table has no state, the information of the person is processed, and only the comparison result needs to be fed back. And the acquisition time enters the foreground scheduling time. The collection logic is the same as the demand one. The collected route full result is also put into the DevRouteInfo table.
