Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method, a device, equipment and a storage medium for switching interface configuration information.
Background
OSPF (Open Shortest Path First) is a dynamic routing protocol in the autonomous system based on link state, and the protocol forms a link state database by exchanging link state information between three layers of switches, and then generates a routing table by using Shortest Path First algorithm based on the database.
The OSPF protocol supports networks of various sizes, up to several hundred three-layer switches. OSPF can send link state update packets immediately after a change in the routing topology of a network. In the existing application environment, the networking environment is generally fixed, and therefore, configuration information about OSPF is also unchanged for the switching device. Because a certain interface belongs to a certain area and is planned in advance, when the networking environment changes and the network topology changes, the interface configuration information of the OSPF can be modified manually.
In the process of implementing the invention, the inventor finds that the prior art has the following defects:
for a flexible network, such as a vehicle-mounted switching device, when a vehicle enters an unknown area from one area, if the interface configuration information of the OSPF is manually modified each time, a problem of high maintenance cost is caused. Meanwhile, the interface configuration information of the OSPF is modified manually, which is easy to make mistakes, thereby causing the network to be disconnected and being difficult to ensure that the switching equipment can access the network quickly.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of an interface configuration information switching method according to an embodiment of the present invention, where the embodiment is applicable to a case of automatically switching interface configuration information of a network device, and the method may be executed by an interface configuration information switching apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a network device (typically, various interactive devices, such as a vehicle-mounted switch, and the like). Illustratively, the interface configuration information switching method is performed by software built in a vehicle-mounted switch. Accordingly, as shown in fig. 1, the method comprises the following operations:
s110, receiving an OSPF protocol message; wherein the OSPF protocol packet includes a first area ID.
The first area ID may be an area ID included in an OSPF protocol packet received by the current network device.
In the embodiment of the present invention, during the operation process of the network device, the network device receives an OSPF protocol packet from other devices. The OSPF protocol packet sent by each device will carry its own first area ID. The first area ID is also the area ID where the OSPF protocol packet sending device is located.
And S120, if the first area ID is determined not to be consistent with the second area ID of the local record and the current network equipment meets the automatic switching condition in the first area, switching the interface configuration information of the local record according to the interface configuration information of the first area.
The automatic switching condition that the current network device satisfies in the first area may be multiple, and specifically, the automatic switching condition that the current network device satisfies in the first area may be that the number of neighbors of the current network device in the first area satisfies the automatic switching condition, for example, the number of source IPs of OSPF protocol packets that are stored in the current network device and have the same first area ID is greater than or equal to a first preset threshold.
The second area ID may be an area ID in the interface configuration information locally recorded by the current network device. The interface configuration information may be OSPF configuration information of the interface. Alternatively, the interface configuration information may include, but is not limited to, interface IP (Internet Protocol, Protocol for interconnection between networks) and interface area. The interface area is also the network area where the interface is located. The first area is also the area where the network device that sends the OSPF protocol packet to the current network device is located. The auto-switching condition may be a condition for the current network device to automatically switch interface configuration information.
It will be appreciated that each network device will store the corresponding interface configuration information locally. After receiving the OSPF protocol packet sent by the other network device, the current network device may match the first area ID in the OSPF protocol packet with the second area ID of the local record. If the first area ID is determined not to be consistent with the second area ID of the local record and the current network equipment meets the automatic switching condition in the first area, the interface configuration information of the local record can be automatically switched according to the interface configuration information of the first area without manually modifying the interface configuration information of the local record.
In the embodiment of the present invention, when the first area ID in the OSPF protocol message received by the current network device does not match the second area ID recorded locally, it may be determined that the current network device may move to a new area, that is, the first area, in this case, if the current network device determines that the automatic handover condition is satisfied in the new area, it may be determined that the current network device has moved to the new area, and the current network device is triggered to switch the interface configuration information recorded locally, so that the current network device is quickly accessed to the new area. Therefore, the invention solves the problems of high maintenance cost, low efficiency and the like of the prior manual switching of the interface configuration information of the network equipment, realizes the purpose of automatically switching the interface configuration information of the network equipment to access a new area after the network equipment moves to the new network environment area, reduces the maintenance cost of the network equipment and improves the network access speed of the network equipment.
Example two
Fig. 2a is a flowchart of an interface configuration information switching method according to a second embodiment of the present invention, which is embodied based on the foregoing embodiment, and in this embodiment, a specific implementation manner of switching locally recorded interface configuration information according to the interface configuration information of the first area is provided. Accordingly, as shown in fig. 2a, the method of the present embodiment may include:
s210, receiving an OSPF protocol message; wherein the OSPF protocol packet includes a first area ID.
S220, judging whether the first area ID is consistent with a second area ID recorded locally, if so, executing S230; otherwise, S240 is performed.
And S230, normally processing the OSPF protocol message.
In the embodiment of the present invention, if the current network device determines that the first area ID matches the second area ID recorded locally, it indicates that the network area where the current network device is located has not changed, and at this time, the current network device may normally process the received OSPF protocol packet.
S240, classifying the OSPF protocol message according to the first area ID, and storing the OSPF protocol message with the same first area ID according to the classification result.
In the embodiment of the present invention, before the current network device automatically switches the locally recorded interface configuration information according to the interface configuration information of the first area, the received OSPF protocol packet may be statistically stored first. Specifically, OSPF protocol packets with the same first area ID may be stored as one type.
S250, counting and storing the quantity of source IPs of the OSPF protocol messages with the same first area ID and the receiving time of the OSPF protocol messages.
Meanwhile, the current network device can also count and store the number of source IPs of OSPF protocol messages with the same first area ID, and record the receiving time of each OSPF protocol message.
And S260, judging whether the current network equipment meets the automatic switching condition in the first area, if so, executing S270, and otherwise, executing S290.
In an optional embodiment of the present invention, the automatic switching condition may include: the number of source IPs of the OSPF protocol messages with the same first area ID is greater than or equal to a first preset threshold.
The first preset threshold may be set according to an actual requirement, such as 3, 4, or 5, and the embodiment of the present invention does not limit a specific value of the first preset threshold. In general, the first preset threshold value avoids taking an integer of 1, so as to avoid frequent switching of interface configuration information by the current network device. When the current network equipment meets the automatic switching condition in the first area, the current network equipment enters a new network area, and the interface configuration information can be automatically switched.
Correspondingly, whether the current network device meets the automatic switching condition in the first area is judged, that is, whether the number of the source IPs of the OSPF protocol packets with the same first area ID stored by the current network device is greater than or equal to a first preset threshold value is judged. Further, whether the number of valid neighbors of the current network device in the first area is greater than or equal to a first preset threshold value is judged. The valid neighbor is also the network device that successfully sends the OSPF protocol packet to the current network device.
S270, the interface IP recorded locally is replaced by the IP of the network segment where the first area is located, and the interface area recorded locally is replaced by the interface area of the first area.
Specifically, when the current network device automatically switches the interface configuration information, the locally recorded interface IP may be replaced with the IP of the network segment where the first area is located, and the locally recorded interface area may be replaced with the interface area of the first area. It should be noted that the IP after the handover is to avoid overlapping with the IP of other network devices in the first area.
In an optional embodiment of the present invention, the interface configuration information switching method may further include: and if the time difference between the receiving time of the OSPF protocol messages with the same first area ID and the current time is greater than or equal to a second preset threshold value, and the number of the source IPs of the OSPF protocol messages with the same first area ID does not meet the automatic switching condition, deleting all information recorded corresponding to the first area ID.
The second preset threshold may be a time difference threshold set according to actual requirements, such as 40s, and may be specifically set according to the transceiving characteristics of the OSPF protocol packet, and the embodiment of the present invention does not limit a specific numerical value of the second preset threshold.
It is understood that some network devices in the first area may stop sending OSPF protocol packets to the current network device for various reasons, for example, the network device fails, or the network device has left the first area. Therefore, the current network device can delete the locally recorded redundant information sent by the network device. Specifically, the current network device may determine the receiving time of the OSPF protocol packets with the same first area ID, and if it is determined that the time difference between the receiving time of the OSPF protocol packets with the same first area ID and the current time is greater than or equal to a second preset threshold, and the number of source IPs of the OSPF protocol packets with the same first area ID does not satisfy the automatic switching condition, that is, the number of source IPs of the OSPF protocol packets with the same first area ID is less than the first preset threshold, may delete all information recorded corresponding to the first area ID.
And S280, deleting all stored information.
Correspondingly, after the current network device completes the automatic switching of the interface configuration information, the OSPF can establish a neighbor relation with other network devices in the current network area, and can delete all stored information, so as to re-receive the OSPF protocol message sent by other devices, and judge whether the locally recorded interface configuration information needs to be automatically switched according to the received OSPF protocol message.
S290, carrying out packet loss processing on the OSPF protocol message.
In the embodiment of the present invention, if the current network device determines that the current network device does not satisfy the automatic handover condition in the first area, the packet loss processing may be performed on the received OSPF protocol packet.
Fig. 2b is a schematic structural diagram of a vehicle-mounted network domain according to a second embodiment of the present invention. Fig. 2c is a schematic structural diagram of a vehicle-mounted network domain according to a second embodiment of the present invention. In one specific example, as shown in fig. 2b, the networking environment of the simulated fleet includes a total of 3 general areas, area 0, area 1, and area 2. Wherein, the team command car belongs to zone 0, cars 1, 2 and 3 belong to zone 1, and cars 4, 5 and 6 belong to zone 2. Wireless communication connection is adopted in each area. The interfaces connected with each other in each area are in the same network segment, and the vehicles in each area can establish a neighbor relation between each two vehicles. Wherein, the area 1 and the area 2 are respectively connected with different command cars. Taking the car 3 in the area 1 as an example, the interface IP of the car 3 to the outside is 10.11.3.3/24, and the interface area is the area 1. As shown in fig. 2c, when the cart 3 leaves the wireless coverage of area 1 and enters the wireless coverage of area 2, the cart 3 cannot access the wireless network of area 2 without manually modifying the interface configuration information for the cart 3. When the area ID carried in the OSPF protocol message received by the vehicle 3 is found to be inconsistent with the area ID in the interface configuration information recorded locally by the original OSPF protocol, the received OSPF protocol message is directly treated as a bad packet. If the external interface IP of the vehicle in the area 2 is 10.12.3.0 network segments, the interface area is the area 2. When the vehicle 3 enters the coverage area of the wireless network of the area 2 after starting the function of automatically switching the interface configuration information, the vehicle 3 receives HELLO messages respectively sent from the vehicle 4, the vehicle 5 and the vehicle 6 in 3 areas 2. The vehicle 3 determines that the area 2 has 3 neighbors according to the received HELLO message, and meets the automatic switching condition (the number of source IPs of the OSPF protocol message with the same first area ID is greater than or equal to 3), the external interface IP of the vehicle 3 is automatically switched to 10.12.3.3/24, and the interface area is switched to the area 2. At this time, the vehicle 3 may establish a neighbor relationship with other vehicles in the area 2, and simultaneously automatically access the wireless network of the area 2. It should be noted that the vehicles in each area may start the automatic domain switching function to automatically switch the interface configuration information.
Fig. 2d is a schematic diagram of a flow of interface configuration information switching according to a second embodiment of the present invention. Correspondingly, as shown in fig. 2d, the interface configuration information switching process of the vehicle 3 is specifically as follows: firstly, classifying and storing the received OSPF protocol message, and then checking whether a first area ID in the OSPF protocol message is equal to a second area ID in interface configuration information of a local record. If the vehicle is determined to be equal, the message is processed normally, and if the vehicle is not equal, whether the automatic domain switching function is started or not is checked. If the vehicle is confirmed to start the automatic domain switching function, checking whether a neighbor exists in the first area; otherwise, the packet loss processing is carried out on the received OSPF protocol message. If the neighbor is determined to exist, the vehicle 3 is shown to be accessed into the first area (namely the area 2), and the interface configuration information does not need to be automatically switched at the moment; otherwise, checking whether the receiving time of the OSPF protocol message is more than 40 s. If the receiving time of the OSPF protocol message is determined to be more than 40s, deleting the storage information corresponding to the first area ID; otherwise, continuously checking whether the source IP in the OSPF protocol message is recorded in the local record. If the source IP in the OSPF protocol message is not recorded locally, recording can be performed, otherwise, packet loss processing can be performed on the OSPF protocol message. Then, the vehicle 3 may check whether the recorded neighbor information reaches 3, that is, whether the number of the interfaces IP reaches 3. If the number of the recorded neighbor information is determined to reach 3, the vehicle 3 is considered to meet the automatic switching condition in the first area, the interface IP address and the interface area can be changed according to the interface configuration information of the first area to realize automatic switching of the interface configuration information, and all stored information is cleared to accept the OSPF protocol message of the current area again; otherwise, the OSPF protocol message can be subjected to packet loss processing.
In the embodiment of the present invention, when the first area ID in the OSPF protocol message received by the current network device does not match the second area ID recorded locally, it may be determined that the current network device may move to a new area, that is, the first area, in this case, if the current network device determines that the automatic handover condition is satisfied in the new area, it may be determined that the current network device has moved to the new area, and the current network device is triggered to switch the interface configuration information recorded locally, so that the current network device is quickly accessed to the new area. Therefore, the invention solves the problems of high maintenance cost, low efficiency and the like of the prior manual switching of the interface configuration information of the network equipment, realizes the purpose of automatically switching the interface configuration information of the network equipment to access a new area after the network equipment moves to the new network environment area, reduces the maintenance cost of the network equipment and improves the network access speed of the network equipment. It should be noted that any permutation and combination between the technical features in the above embodiments also belong to the scope of the present invention.
