Background technique

In a data communication network (Data Communication Network, DCN) network, multiple network element devices can be set, and two network element devices can be selected from the multiple network element devices as the main network element device and the standby network element device, respectively. Other network element devices in multiple network element devices can be managed through the main network element device or the standby network element device.

For example, multiple network element devices are partitioned to obtain a partition area 1 and a partition area 2, and the primary network element device and the backup network element device belong to both the partition area 1 and the partition area 2.

For the main network element device and the backup network element device, in addition to establishing the routing table in the entire divided area based on the received network element device ID and IP address sent by different network element devices, it is also necessary to In the device ID and IP address, check whether the same network element device ID or the same IP address exists. If different network element devices are set with the same network element device ID or the same IP address, it means that there is a conflicting network element device ID or IP address, and then it is necessary to send a message carrying the conflicting network element device ID or IP address to the designated terminal. Conflict warning message for conflicting IP addresses. The network administrator can view the conflict warning prompt message in the terminal, and based on the conflict warning prompt message, modify the network element device identifier or IP address of any one of the conflicting network element devices.

In the process of realizing the present disclosure, the inventors found at least the following problems:

The active network element device and the standby network element device need to send local network element device identifiers and IP addresses to neighbor network element devices in all divided areas at the same time. Furthermore, since the primary network element device and the standby network element device belong to all divided areas at the same time, the primary network element device can receive at least two network element device identifiers and at least two IP addresses sent by the standby network element device, and at least two network element The device identifiers are the same, and at least two IP addresses are also the same, so the main network element device will perform alarm processing, but this belongs to false alarm processing.

By means of the above-mentioned drawings, certain embodiments of the present disclosure have been shown and will be described in more detail hereinafter. These drawings and written description are not intended to limit the scope of the disclosed concept in any way, but to illustrate the disclosed concept for those skilled in the art by referring to specific embodiments.

detailed description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

An exemplary embodiment of the present disclosure provides a method for alerting, which can be executed in a DCN. DCNs include single-domain DCNs and multi-domain DCNs. Among them, as shown in Figure 1, the DCN of the multi-domain type includes multiple regional networks, and different regional networks communicate through the main gateway network element device (Gateway Network Element, GNE) and the standby GNE, and other network elements in different regional networks The device (Network Element, NE) cannot communicate. In this way, each area network can maintain its own routing table, and the size of the routing table is small.

When the operator needs to manage devices in multiple area networks, if the main GNE and the standby GNE need to be managed, the main GNE and the standby GNE can be managed directly through the terminal. If other NEs need to be managed, you can firstly establish a connection between the terminal and the main GNE and the standby GNE, and manage other NEs through the main GNE and the standby GNE.

An exemplary embodiment of the present disclosure provides a method for alerting, as shown in FIG. 2 , the processing flow of the method may include the following steps:

In step S210, the first network element device acquires a local network element device identifier, an IP address, and a Media Access Control Address (MAC) address.

In implementation, the network element device identifier can also be called NEID (Network Element Identifier), and the IP address can also be called NEIP (Network Element IP). The NEID and NEIP can be configured by the operator for each network element device, and can be stored In the memory of each network element device.

The first network element device in the embodiment of the present disclosure may be the active GNE, the standby GNE, or other NEs. The second network element device may be the active GNE or the standby GNE. The first network element device can obtain a local network element device identifier and IP address, and the first network element device can also obtain a local MAC address.

Step S220, the first network element device sends the network element device identifier, IP address and MAC address to the second network element device.

Step S230, the second network element device receives the network element device identifier, IP address and MAC address of the first network element device.

In an implementation, the first network element device may send the obtained network element device identifier, IP address, and MAC address to the second network element device.

Optionally, the first network element device may send the obtained network element device identifier, IP address, and MAC address to the second network element device in a flooding manner.

In practical application, as shown in FIG. 1 , the first network element device may be NE1, and NE1 belongs to area network A, and there are NE2, NE3, primary GNE, and backup GNE in area network A. Area network B includes NE4, NE5, NE6, active GNE, and standby GNE.

In area network A, the device adjacent to NE1 is NE2, and the device adjacent to NE2 is the master GNE. Therefore, NE1 can obtain NE1's NEID and NEIP, and then send NE1's NEID and NEIP to NE2. NE2 can receive NE1's NEID and NEIP sent by NE1, store the received NE1's NEID and NEIP, and forward the received NE1's NEID and NEIP to the master GNE. The master GNE can receive the NEID and NEIP of NE1 forwarded by NE2, and store the received NEID and NEIP of NE1. Similarly, NE2 also sends NE2's NEID and NEIP to other devices, and all devices in area network A send their NEIDs and NEIPs to other devices in area network A. Furthermore, all devices in the area network A can receive the NEID and NEIP of other devices in the area network A. For each device in the area network A, a routing table corresponding to the area network A can be established based on the local NEID and NEIP, and the NEID and NEIP of other devices.

For the active GNE and the standby GNE, in addition to establishing the routing table corresponding to the area network A, the routing table corresponding to the area network B can also be established based on the same method.

For the active GNE and the standby GNE, in addition to establishing the routing table corresponding to each area network, it can also detect whether conflicting NEIDs and NEIPs are set in all devices in each area network.

Optionally, step S220 may include: the first network element device sends a first packet carrying the network element device identifier and IP address to the second network element device; the first network element device sends a packet carrying the The second packet of the MAC address. Correspondingly, step S230 may include: the second network element device receives the first message, and acquires the network element device identifier, IP address and first routing identifier carried in the first message; the second network element device receives the second message to acquire the MAC address and the second routing identifier carried in the second packet.

In an implementation, the first network element device may send the network element device identifier, the IP address and the MAC address to the second network element device through two messages respectively. Specifically, the network element device identifier and IP address may be sent to the second network element device through the first message, and the MAC address may be sent to the second network element device through the second message. Wherein, the first message may be a type of LSA in Data Communication Network Opaque Link-State Advertisement (DCN Opaque LSA). The second packet may be a type 10 LSA in the DCN Opaque LSA. In practical applications, the Type 10 LSA can be extended, and the MAC address can be added to the extension position of the Type 10 LSA to obtain a second message, which can also be called a DCN SysMac Opaque LSA. A MAC address can take up 6 bytes of space.

The second network element device may receive DCNOpaque LSAs sent by network element devices in different area networks from different processes, and the second network element device may isolate network element devices in different area networks through different processes. For example, there are two area networks, including area network A and area network B, and their corresponding processes are DCN OSPF (OpenShortest Path First, open shortest path first protocol) 65534 and DCN OSPF 65535 respectively.

Since the network element device identifier, IP address, and MAC address are sent to the second network element device through two packets respectively, in order to determine whether the network element device identifier, IP address, and MAC address carried in different packets correspond to the same network element The meta-device can be judged by the routing identifier in the packet. Wherein, the router identifier may also be referred to as a Router-ID (Router-Identifier).

Optionally, if the first routing identifier is the same as the second routing identifier, the network element device identifier, IP address and MAC address carried in the second message are determined as the first network element device The NE device ID, IP address, and MAC address of the network element.

In implementation, if the first routing identifier is the same as the second routing identifier, and the first routing identifier or the second routing identifier corresponds to the first network element device, the network element device identifier, IP The address and the MAC address carried in the second message are determined as the network element device identifier, IP address and MAC address of the first network element device. Alternatively, if the first route identifier is the same as the second route identifier, the network element device identifier, IP address and MAC address carried in the second message may be determined as the same network element device. Meta-device ID, IP address and MAC address. The network element device identifier, IP address, and MAC address of the same network element device may be used as a triplet.

Step S240, if the network element device identifier currently received by the second network element device is the same as any network element device identifier in other received network element device identifiers, the second network element device determines that any network element device identifier corresponds to Whether the MAC address of the network element device is different from the currently received MAC address; if the MAC address corresponding to any network element device identifier is not the same as the currently received MAC address, the second network element device sends a A warning message for conflicting device IDs.

In an implementation, after determining the multiple triplets, the second network element device can compare whether there are any at least two network element device identifiers in the multiple triplets that are the same, and if there are any at least two network element device identifiers in the multiple triplets. If the two network element device identifiers are the same, it may be further compared whether the MAC addresses in the triplets to which they belong are the same. If the MAC addresses in the triplets to which they belong are the same, it means that the same network element device identifiers correspond to the same network element device, such as the active GNE or the standby GNE, and there is no conflict in fact, and you do not need to report the conflict at this time . If the MAC addresses in the triplets they belong to are different, it means that these same network element device identifiers correspond to different network element devices, and a conflict occurs. At this time, the second network element device can send Conflict warning message of meta-device ID. Specifically, a conflict warning prompt message carrying the currently received network element device identifier can be sent to the terminal, so that the operator can view the conflict warning prompt message in the terminal, and check which network element device settings are made for the conflict warning prompt message one by one. have the same network element device ID, and then the network element device ID of the detected network element device can be modified.

Step S250, if the IP address currently received by the second network element device is the same as any IP address among other received IP addresses, the second network element device determines whether the MAC address corresponding to any IP address is the same as the currently received IP address If the MAC address corresponding to any IP address is different from the currently received MAC address, the second network element device sends a conflict warning message carrying the currently received IP address.

In the implementation, based on the same method as the identification of the network element device, if the IP address currently received by the second network element device is the same as any IP address among other received IP addresses, the second network element device determines that either Whether the MAC address corresponding to the IP address is different from the currently received MAC address; if the MAC address corresponding to any IP address is different from the currently received MAC address, the second network element device sends a Address conflict warning message. If the IP address currently received by the second network element device is the same as any IP address in other received IP addresses, the second network element device determines whether the MAC address corresponding to any IP address is the same as the currently received MAC address Not the same; if the MAC address corresponding to any IP address is the same as the currently received MAC address, the second network element device is prohibited from sending a conflict warning prompt message carrying the currently received IP address.

In practical applications, if the NE device ID and IP address of the same NE device conflict with those of other NE devices at the same time, the conflicting NE device ID and IP address can be reported at the same time.

Optionally, in order to further determine whether the same network element device identifier or IP address corresponds to the same network element device, in addition to sending the MAC address to the second network element device, the first network element device, when the first network element device obtains When the local network element device identifier, IP address, and MAC address are used, the first network element device can also obtain the current time stamp information, and send the time stamp information to the second network element device.

Correspondingly, the second network element device receives the time stamp information sent by the first network element device; If the identifiers are the same, the second network element device determines whether the timestamp information corresponding to any network element device identifier is different from the currently received timestamp information; if the MAC address corresponding to any network element device identifier is the same as the currently received MAC address If the addresses are not the same, or the time stamp information corresponding to any network element device ID is different from the currently received time stamp information, the second network element device sends a conflict warning prompt message carrying the currently received network element device ID.

If the IP address currently received by the second network element device is the same as any IP address in the other received IP addresses, the second network element device determines whether the timestamp information corresponding to any network element device identifier is the same as the currently received The time stamp information is different; if the MAC address corresponding to any IP address is different from the currently received MAC address, or the time stamp information corresponding to any network element device identifier is different from the currently received time stamp information, the second The network element device then sends a conflict warning prompt message carrying the currently received IP address.

In implementation, the first network element device can obtain the local MAC address and current timestamp information, combine the MAC address and current timestamp information to obtain a 12-byte identifier, and combine the combined MAC address and The current time stamp information is sent to the second network element device.

If the network element device identifier currently received by the second network element device is the same as any network element device identifier in other received network element device identifiers, the second network element device can determine the currently received combined MAC address Whether the combined MAC address corresponding to the current time stamp information and any network element device identifier is the same as the current time stamp information. If the currently received combined MAC address and current timestamp information are the same as the combined MAC address and current timestamp information corresponding to any network element device identifier, it means that these same network element device identifiers correspond to The same network element device, such as the active GNE or the standby GNE, does not actually conflict, so it is not necessary to report the conflict at this time. If they are different, it means that the same network element device identifiers correspond to different network element devices, and a conflict occurs. At this time, the second network element device can send a conflict warning prompt message carrying the currently received network element device identifier.

Similarly, if the IP address currently received by the second network element device is the same as any one of the received other IP addresses, the second network element device can determine the currently received combined MAC address and the current IP address. Whether the combined MAC address corresponding to the time stamp information and any IP address is the same as the current time stamp information. If the currently received combined MAC address and current timestamp information are the same as the combined MAC address and current timestamp information corresponding to any IP address, it means that these same IP addresses correspond to the same network element The equipment, such as the active GNE or the standby GNE, does not actually have a conflict, so it is not necessary to report the conflict at this time. If they are different, it means that the same IP addresses correspond to different network element devices, and a conflict occurs. At this time, the second network element device may send a conflict warning prompt message carrying the currently received IP address.

Through the method provided by the embodiments of the present disclosure, it is possible to determine whether the same network element device identifier or IP address corresponds to a different network element device by means of the MAC address of the network element device. If the same network element device identifier or IP address is determined to be The conflict alarm message is sent only corresponding to different network element devices, so as to avoid false positives.
