Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a neighbor establishment method and apparatus.
Background
ENDP (Enhanced Neighbor Discovery Protocol) is a Protocol for automatically discovering neighbors. The use of the protocol can greatly simplify the network configuration and reduce the maintenance workload of network management staff. For example, a VTEP (VXLAN Tunnel End Point) in VXLAN (Virtual eXtensible Local Area Network) may automatically discover a neighbor VTEP through ENDP and automatically establish a neighbor relationship.
In practical application, after discovering the neighbor network device and establishing the neighbor relationship, a Tunnel may be automatically established between the home network device and the neighbor network device, so as to perform message interaction between the network devices. The tunnel is a virtual point-to-point connection, and both ends of the tunnel need to encapsulate and decapsulate the data packet.
Specifically, after the home network device learns the neighbor network device through the neighbor protocol module and establishes the neighbor relationship, the tunnel module may be notified according to the neighbor network device information to create the tunnel corresponding to the neighbor network device. And when the local network device and the neighbor network device are disconnected from the neighbor relationship, the neighbor protocol module also informs the tunnel module to delete the tunnel corresponding to the neighbor network device. After receiving the tunnel deleting message sent by the neighbor protocol module, the tunnel module deletes the corresponding tunnel.
It can be seen that, in the prior art, tunnel creation or deletion by the tunnel module is performed according to the notification message sent by the neighbor protocol module. However, in some cases, such as during a short network oscillation, the network device may need to perform procedures of deleting a tunnel, learning neighbors, and establishing a tunnel, which take a long time. This may result in the network device being shut down for a longer period of time and thus unable to provide normal network service.
Disclosure of Invention
The embodiment of the invention aims to provide a neighbor establishing method and a neighbor establishing device so as to improve the efficiency of neighbor establishment and enable network equipment to provide normal network service. The specific technical scheme is as follows:
in a first aspect, an embodiment of the present invention provides a neighbor establishment method, which is applied to a tunnel module of any network device, and the method includes:
when a tunnel deleting message is received, acquiring a destination address of a tunnel to be deleted;
judging whether the connection to the opposite terminal network equipment can be carried out or not according to the destination address;
if not, deleting the tunnel to be deleted; if yes, according to the destination address of the tunnel to be deleted, a neighbor protocol module is informed to establish a neighbor relation with the opposite terminal network equipment.
In a second aspect, an embodiment of the present invention provides a neighbor establishing apparatus, which is applied to a tunnel module of any network device, where the apparatus includes:
the device comprises an acquisition unit, a processing unit and a processing unit, wherein the acquisition unit is used for acquiring a destination address of a tunnel to be deleted when a tunnel deletion message is received;
a judging unit, configured to judge whether the connection to the peer network device is possible according to the destination address;
the processing unit is used for deleting the tunnel to be deleted when the judgment result of the judging unit is that the tunnel cannot be deleted; and when the judgment result of the judgment unit is yes, informing a neighbor protocol module to establish a neighbor relation with the opposite terminal network equipment according to the destination address of the tunnel to be deleted.
The embodiment of the invention provides a neighbor establishing method and a neighbor establishing device, when a tunnel module receives a tunnel deleting message, the tunnel module does not directly delete the tunnel to be deleted, but judges whether the tunnel to be deleted can be connected to opposite-end network equipment, and if the tunnel to be deleted can not be connected to the opposite-end network equipment, the tunnel to be deleted is deleted; if it can, it indicates that the neighbor relation may be disconnected only briefly before, the home network device should still maintain the neighbor relation with the peer network device. In this case, the tunnel module may not delete the tunnel to be deleted, and may notify the neighbor protocol module to establish a neighbor relationship with the peer network device according to the destination address of the tunnel to be deleted. That is to say, when transient network oscillation occurs, the local network device does not need to delete the tunnel, learn the neighbor and establish the tunnel, and can directly establish the neighbor relationship with the opposite network device, so that the efficiency of neighbor establishment can be improved, and the network device can provide normal network service.

Detailed Description
In order to improve the efficiency of neighbor establishment and enable network equipment to provide normal network services, the embodiment of the invention provides a neighbor establishment method and a neighbor establishment device.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
In the embodiment of the present invention, in order to improve the efficiency of neighbor establishment and enable a network device to provide a normal network service, an embodiment of the present invention provides a neighbor establishment method, which is applied to a tunnel module of any network device, and as shown in fig. 1, the process may include the following steps:
s101, when receiving the tunnel deleting message, acquiring the destination address of the tunnel to be deleted.
In practical applications, the tunnel module of the network device may receive the tunnel deletion message. In particular, the tunnel deletion message may be sent by a neighbor protocol module.
For example, when network oscillation occurs and the network device disconnects the neighbor relationship with any neighbor network device, the neighbor protocol module sends a tunnel deletion message to the tunnel module to notify the tunnel module to delete the tunnel corresponding to the neighbor network device.
Or, when the main/standby switch occurs, that is, when the main/standby switch occurs between the main board and the back board in the network device, or when the main/standby process is switched, in order to ensure that the data between the neighbor protocol module of the network device and the tunnel module after the main/standby switch is consistent, thereby ensuring the accuracy of establishing the neighbor relationship, the neighbor protocol module of the main board after the switch will be smooth with the tunnel module.
Specifically, when the neighbor protocol module notifies the tunnel module to start smoothly, the neighbor protocol module may notify the tunnel module to re-create the tunnel according to its own neighbor information, for example, the neighbor information synchronized by the previous motherboard, or the neighbor information acquired from the database by itself. After receiving the message of creating the tunnel, the tunnel module checks whether the tunnel is already created locally, if so, the tunnel is set with a piece of mark information and returned; if not, a tunnel is newly created and a flag information is set. That is, tunnels that are consistent with the neighbor protocol modules will contain flag information, rather than tunnels created from a neighbor protocol module, such as automatic tunnels created before the tunnel module and by a particular neighbor protocol module, will not contain flag information.
After the tunnel module completes the establishment of the tunnel concatenation flag information according to the notification message sent by the neighbor protocol module, a response message of the completion of the establishment can be sent to the neighbor protocol module. After receiving the response message, the neighbor protocol module may notify the tunnel module of the end of smoothing. And the tunnel module receives the smoothing end message, can traverse all locally established tunnels, acquires the mark information of each tunnel, and determines the tunnel without the mark information as the tunnel to be deleted.
Therefore, in the embodiment of the present invention, the tunnel deletion message received by the tunnel module may be a message sent by the neighbor protocol module to delete a certain tunnel. Or receiving a smoothing end message sent by the neighbor protocol module in the smoothing process.
In the embodiment of the invention, after receiving the tunnel deletion message, the network equipment can acquire the destination address of the tunnel to be deleted. Specifically, the network device receives the tunnel deletion message, and obtains the destination address of the tunnel to be deleted, which may be implemented as follows:
for example, a tunnel deletion message received by the network device may carry a destination address of a tunnel to be deleted; or, the tunnel deletion message may carry identification information of the tunnel to be deleted, and the network device may search a destination address corresponding to the identification information of the tunnel to be deleted according to a correspondence between each locally stored tunnel identification information and the destination address, and determine the found destination address as the destination address of the tunnel to be deleted.
Since one tunnel corresponds to one neighbor network device, when the network device acquires the destination address of the tunnel to be deleted, that is, the network device acquires the address of the opposite-end network device corresponding to the tunnel to be deleted.
S102, judging whether the connection to the opposite terminal network equipment can be carried out or not according to the destination address; if not, step S103 is executed, and if so, step S104 is executed.
In practical applications, when the neighbor protocol module sends the tunnel deletion message to the tunnel module, it may be only because of a short network oscillation. In fact, after a period of time, when the tunnel module receives the tunnel deletion message, the network may have recovered to normal, and the peer network device corresponding to the tunnel to be deleted may have been connected.
In this case, if the tunnel module deletes the tunnel to be deleted, the subsequent neighbor protocol module learns the peer network device corresponding to the tunnel to be deleted again, and needs to establish a neighbor relationship with the peer network device again and reestablish the tunnel.
In the embodiment of the invention, in order to improve the efficiency of neighbor establishment and enable the network device to provide normal network service, after receiving the tunnel deletion message, the tunnel module does not immediately delete the tunnel to be deleted, but can judge whether the tunnel to be deleted can be connected to the opposite-end network device according to the destination address and the source address of the tunnel to be deleted.
If the connection to the opposite-end network device cannot be achieved, the fact that the opposite-end network device is possibly offline or the network failure is not recovered is indicated, and in this case, the tunnel module may delete the tunnel to be deleted.
If the connection to the peer network device is possible, it indicates that the neighbor protocol module sends the tunnel deletion message, which may be because the local network device and the peer network device are disconnected from the neighbor relation due to transient network oscillation. In this case, it indicates that the home network device may establish a neighbor relationship with the peer network device, and in order to quickly establish a neighbor relationship with the peer network device and avoid performing tunnel deletion, neighbor learning, and tunnel establishment, the difference from the establishment of a corresponding tunnel according to a neighbor relationship is that, in this embodiment, the tunnel module may notify the neighbor protocol module to establish a neighbor relationship with the peer network device according to a destination address of a tunnel to be deleted, that is, establish a corresponding neighbor relationship according to tunnel information.
In an implementation manner, when the tunnel module determines whether the tunnel module can be connected to the peer network device according to the destination address and the source address of the tunnel to be deleted, the tunnel module may send a detection packet to the peer network device according to the destination address and the source address. After receiving the detection message, the opposite-end network device may send a response message to the home-end network device, so that when the tunnel module receives the response message sent by the opposite-end network device, it is determined that the tunnel module can be connected to the opposite-end network device.
The detection Message sent by the tunnel module may be an ICMP (Internet Control Message Protocol) Message. ICMP is a sub-protocol of the TCP/IP protocol family that is used to pass control messages between IP hosts and routers. Control messages refer to messages of the network itself, such as network traffic down, whether a host is reachable, whether routing is available, etc.
For example, the tunnel module may send the detection packet to the peer network device according to the destination address and the source address of the tunnel to be deleted. And then detecting whether a response message sent by the opposite terminal network equipment is received, and if so, determining that the opposite terminal network equipment can be connected.
Optionally, in order to avoid that the detection packet sent by the local network device cannot be received by the opposite network device due to failure of timely recovery due to network failure, the local network device may send the packet multiple times. For example, the home network device may send a detection packet to the peer network device according to a set time interval, such as 1 millisecond, 2 milliseconds, 5 milliseconds, and the like, so as to improve the possibility that the peer network device receives the packet. Wherein, in order to detect whether the connection to the opposite terminal network device is possible as soon as possible, a shorter time interval may be set. On the basis of the above embodiment, the tunnel module may send the detection packet to the peer network device according to a preset time interval, and determine whether the number of times of sending the detection packet reaches a preset maximum number of times of sending.
If the response message sent by the opposite terminal network equipment is not received within a certain time interval and the preset maximum sending times is reached, determining that the opposite terminal network equipment cannot be connected.
Specifically, the tunnel module may preset a time interval and detect the maximum number of times of sending a message, and after sending a detection message, the tunnel module may detect whether a response message sent by the peer network device is received within a time interval, and if the response message is received, it is determined that the tunnel module can be connected to the peer network device, and the detection message is not sent to the peer network device. If not, sending the detection message to the opposite terminal network equipment again, continuously detecting whether a response message sent by the opposite terminal network equipment is received in the time interval, meanwhile, judging whether the number of times of the sent detection message reaches the set maximum sending number, and if the response message sent by the opposite terminal network equipment is not received in any time interval and the set maximum sending number is reached, determining that the connection to the opposite terminal network equipment cannot be realized.
In order to improve the efficiency of detecting whether the network device can be connected to the opposite terminal, avoid the detection process from occupying too long time, and serve as a replacement scheme for judging whether the number of times of detecting messages reaches the set maximum sending number, optionally, the tunnel module can preset the maximum time length, and when a response message is received within the maximum time length, the tunnel module can be determined to be connected to the opposite terminal network device; when the response message is not received within the maximum duration, the tunnel module will not continue to detect, and may determine that the connection to the peer network device is not possible, the peer network device may indeed be offline, or the network has not been recovered.
Wherein the preset maximum duration is greater than the set time interval. Of course, the tunnel module may only send the detection message once within the preset maximum duration range, or may send the detection message multiple times according to the set time interval.
In another implementation, when the home network device determines whether to connect to the peer network device according to the destination address and the source address, it may also create a Bidirectional Forwarding Detection (BFD) session with the peer network device according to the destination address and the source address; and when the BFD session is UP, determining that the opposite terminal network equipment can be connected.
BFD (Bidirectional Forwarding Detection) is a general, standardized, media independent and protocol independent fast fault Detection mechanism, and can be used for detecting link states in a network, and ensuring that communication faults between network devices can be detected fast, so that measures can be taken in time, and service continuous operation is ensured.
After the home terminal network device creates the BFD session with the opposite terminal network device, it can further detect whether the BFD session is in the UP state. Specifically, the home network device may periodically detect whether the BFD session is in the UP state.
S103, deleting the tunnel to be deleted.
When the home network device determines that the home network device cannot be connected to the peer network device, it indicates that the peer network device may indeed be offline or the network failure is not recovered, in which case, the tunnel module may delete the tunnel to be deleted.
S104, according to the destination address of the tunnel to be deleted, notifying a neighbor protocol module to establish a neighbor relation with the opposite terminal network equipment.
When the home network device determines that the home network device can be connected to the peer network device, it indicates that the neighbor protocol module sends the tunnel deletion message, which may be because the home network device and the peer network device are disconnected from each other due to network oscillation. In this case, it indicates that the home network device may establish a neighbor relationship with the peer network device, and in order to quickly establish a neighbor relationship with the peer network device and avoid performing tunnel deletion, neighbor learning, and tunnel establishment, the tunnel module may notify the neighbor protocol module of establishing a neighbor relationship with the peer network device according to a destination address of a tunnel to be deleted.
The embodiment of the invention provides a neighbor establishing method, when a tunnel module receives a tunnel deleting message, the tunnel module does not directly delete the tunnel to be deleted, but judges whether the tunnel to be deleted can be connected to opposite-end network equipment, if not, the tunnel to be deleted is deleted; if it can, it indicates that the neighbor relation may be disconnected only briefly before, the home network device should still maintain the neighbor relation with the peer network device. In this case, the tunnel module may not delete the tunnel to be deleted, and may notify the neighbor protocol module to establish a neighbor relationship with the peer network device according to the destination address of the tunnel to be deleted. That is to say, when transient network oscillation occurs, the local network device does not need to delete the tunnel, learn the neighbor and establish the tunnel, and can directly establish the neighbor relationship with the opposite network device, so that the efficiency of neighbor establishment can be improved, and the network device can provide normal network service.
