Fig. 1 shows a flow chart of an IP address availability detection method of an embodiment of the present invention.
The method comprises the following steps:
s101, analyzing the interface work order, and acquiring the IP address to be checked and the network to be checked in the interface work order.
And analyzing the interface work order to analyze the IP address and the network information, namely the IP address to be verified and the network to be verified.
In this embodiment, the networks capable of implementing IP address verification include a metropolitan area network and a 163 network. The IP address to be checked can be a double stack address, and can also be a single IP address in a V4 or V6 format, or an IP address section in a V4 or V6 format. The availability check can be carried out on V4, V6 and single address or address segment of double stack type.
S102, searching the core equipment group corresponding to the network to be checked in a core equipment table configured in advance; the core device group comprises a plurality of core devices.
The core device table is a configured table input in advance by the system, and is used for recording each core device in the metropolitan area network and each core device in the 163 network.
In step S101, the network to be verified has been analyzed and is matched with the corresponding network in the core device table, that is, the information of each core device in the corresponding network can be matched.
As an embodiment of the present invention, if the network to be verified analyzed in S101 is a metropolitan area network, all core devices and related information thereof corresponding to the metropolitan area network are matched in the core device table.
S103, logging in each core device, verifying the IP address to be verified to obtain a plurality of verification results, and judging the availability of the IP address according to the verification results to obtain detection results.
In step S102, each core device in the core device group corresponding to the network to be verified has been matched, in step S103, each core device needs to be respectively logged in, and the IP address to be verified is verified on each core device, so that a plurality of verification results can be obtained, that is, each core device corresponds to one verification result.
As an embodiment of the present invention, as shown in fig. 2, the IP address to be verified is verified, and according to the different address types of the IP address to be verified, the verification process is also divided into three cases:
the first condition is as follows: the address type of the IP address to be checked is a double-stack address. At this time, the address is required to be split according to the separator, and the split address is used for obtaining the single IP address with the address type to be checked being V4 or V6 format or the IP address of the IP address section with the V4 or V6 format; and checking according to the checking process of the corresponding address type. It should be noted that, when the IP address to be verified is a dual-stack address, it is necessary to simultaneously satisfy that each split address passes verification, and then a list can be returned: the address is available; if one address check fails, returning a list: the address is not available.
Case two: the address type of the IP address to be checked is a single IP address in a V4 or V6 format. At the moment, the IP address to be verified needs to be subjected to ping test, if the ping is successful, the IP address is occupied, and the IP address directly returned is unavailable; if the ping is not connected, further routing detection is needed, and IP address verification is carried out according to the routing detection result.
As an embodiment of the present invention, the ping test is to send an ICMP message and listen to an echo reply packet, and if the echo reply packet can be listened, ping is performed; otherwise ping is not enabled.
Case three: the address type of the IP address to be checked is an IP address section in a V4 or V6 format. At this time, further routing detection is required, and IP address verification is performed according to the routing detection result.
As an embodiment of the present invention, the route detection process includes:
firstly, carrying out long-match routing detection on an IP address to be verified, if a detection result is returned, the IP address is occupied, and the IP address is directly returned and unavailable; and if no detection result is returned, continuing to execute the ordinary route detection.
In this embodiment, long-match route detection. The long-match routing detection can obtain two results, namely return of a detection result and return of no detection result. When a detection result is returned, the IP address to be detected is judged to be occupied, so that the routing detection result, namely the verification result, is as follows: the IP address is not available. When no detection result is returned, the route detection result cannot be obtained, and further ordinary route detection needs to be performed.
In the ordinary routing detection, the next-hop routing address and the exit port need to be checked, and the following three detection results may exist in checking:
the first result is: no unique egress address or multiple egress addresses are found; at the moment, a check result can be obtained, namely the IP address is judged to be abnormal, and the direct address return fails;
the second result is: finding a unique outlet address, wherein the port accords with a corresponding port name rule; at this time, a verification result can be obtained, namely, the IP address detection on the current core equipment is judged to be passed, and the next core equipment verification is started;
the third result is: a unique egress address is found but the port does not comply with the corresponding port name rule.
The invention intelligently utilizes various combination modes such as ping test, long-match route detection, common route detection and the like, and improves the detection accuracy.

Specifically, the metro network verification method includes:
step 1: firstly, an exit address of a next hop route is required to be obtained, and corresponding exit equipment is found according to the exit address of the next hop route, and is marked as first exit equipment at the moment; judging whether the first outlet equipment is metropolitan area network equipment or not, and if so, executing the step 2; otherwise, a check result is obtained, namely the IP address is abnormal, and the direct receipt of the address fails.
Step 2: logging in the first outlet equipment, and carrying out routing detection on the first outlet equipment;
in this embodiment, the route detection process includes:
firstly, carrying out long-match routing detection on an IP address to be verified, if a detection result is returned, the IP address is occupied, and the IP address is directly returned and unavailable; and if no detection result is returned, continuing to execute the ordinary route detection.
In this embodiment, long-match route detection. The long-match routing detection can obtain two results, namely return of a detection result and return of no detection result. When a detection result is returned, the IP address to be detected is judged to be occupied, so that the routing detection result, namely the verification result, is as follows: the IP address is not available. When no detection result is returned, the route detection result cannot be obtained, and further ordinary route detection needs to be performed.
In the ordinary routing detection, the next-hop routing address and the exit port need to be checked, and the following three detection results may exist in checking:
the first result is: no unique egress address or multiple egress addresses are found; at the moment, a check result can be obtained, namely the IP address is judged to be abnormal, and the direct address return fails;
the second result is: finding a unique outlet address, wherein the port accords with a corresponding port name rule; at this time, a verification result can be obtained, namely, the IP address detection on the current core equipment is judged to be passed, and the next core equipment verification is started;
the third result is: a unique egress address is found but the port does not comply with the corresponding port name rule.
And step 3: and if the routing detection result is a third result, namely the unique exit address is found, but the port does not accord with the corresponding port name rule, adding 1 to the cycle number. And setting a counter to count and accumulate the times of executing the route detection process. Setting the initial cycle number as 0, and adding 1 to the cycle number when the routing detection process is performed once and the obtained routing detection result is a third result; the number of cycles after adding 1 is the current number of cycles.
And 4, step 4: judging whether the current cycle number reaches a preset cycle number, if so, executing the step 5; otherwise, returning to the step 1, namely when the current cycle time does not reach the preset cycle time, circularly executing the route detection process until the cycle time reaches the preset cycle time. And when the current cycle number reaches the preset cycle number, the current cycle number is equal to the preset cycle number.
And 5: finding a corresponding second outlet device according to the outlet address of the next hop route, judging whether the second outlet device is in the core device group, if so, obtaining a verification result, namely that the IP address detection on the current core device passes, and starting the next core device verification; otherwise, the check result is: the IP address is not available.
Specifically, the 163-net verification method comprises the following steps:
finding out corresponding outlet equipment according to an outlet address of a next hop route, judging whether the outlet equipment is in the core equipment group, if so, obtaining a verification result, namely that the IP address on the current core equipment passes the detection, and starting the next core equipment to verify; otherwise, the check result is: the IP address is not available.
In step S103, the availability of the IP address is determined according to the verification result.
In S103, there are multiple verification results, including that the IP address detection on the current core device passes, the IP address is unavailable, the IP address is abnormal, the direct receipt of the address fails, and the like; in the three verification results, the IP address can be used only if the IP address detection on all the core equipment passes; otherwise the IP address is not available.
Optionally, when the IP address to be checked is a dual stack address, it is necessary to simultaneously satisfy that each split address passes through the check, and then the list can be returned: the address is available; if one address check fails, returning a list: the address is not available.
