Description

Method, device, equipment and storage medium for determining service message forwarding mode
Technical Field
The embodiment of the invention relates to the technical field of computer communication, in particular to a method, a device, equipment and a storage medium for determining a service message forwarding mode.
Background
Fig. 1a is a schematic diagram of a scenario of a message recording method in the prior art, where a recording device is used to record all messages passing through a network device a and a network device B. Connected to network device a and network device B are 3 network systems, represented by networks C, D and E, respectively. The connection line is a solid line indicating a link currently available for data transmission, and the connection line is a broken line indicating a link currently unavailable for data transmission (i.e., a blocked link). If the current link for data transmission fails, the network and the recording device can switch to another link to transmit data. In the figure, the networks C, D and E all have communication with each other, so that the communication between the networks D and E only passes through the network device a, and the communication between the networks D and C only passes through the network device a and the network device B, so that the recording device needs to mirror the messages on the network devices a and B to the port 10 of the network device B and the port 5 of the network device a at the same time when recording the messages of the whole network.
Referring to fig. 1a, ports 5, 1 and 2 on network device a and ports 3, 10 and 13 on network device B are scribed into virtual local area network N1, port 4 on network device a and port 14 on network device B are scribed into virtual local area network N2. The ports 6, 7 and 8 on the network device a are used as mirror sources and mirror the received/transmitted messages to the port 4, and the messages on the network device a are broadcast to the port 5 and the port 10 of the network device B in the virtual local area network N1 through the ports 4-2. Similarly, the ports 9, 11 and 12 on the network device B are used as mirror sources and mirror the received/transmitted messages to the port 14, so that the messages on the network device B reach the virtual local area network N1 through the link between the port 14 and the port 13 and are broadcast to the port 10 and the port 5 of the network device a in the virtual local area network N1. In fig. 1a, the link between the network device a and the recording device is not in operation, but in order to receive the entire network message after the link between the recording device and the network device is switched, the messages on the network devices a and B are still mirrored to the port 4 on the network device a in real time.
The inventor finds that the following defects exist in the prior art in the process of realizing the invention: since the links between the recording device and the two network devices are active at the same time and only one link is active, it is unnecessary to mirror the messages in the network to the device where the inactive link is located, which is not useful and wasteful of network resources until the link between the network device and the recording device is not switched.

Example 1
Fig. 1b is a flowchart of a method for determining a service packet forwarding manner according to a first embodiment of the present invention, where the method may be applied to a first network device, and the embodiment may be applicable to a case of determining a service packet forwarding manner in a network system, where the method may be performed by a device for determining a service packet forwarding manner, and the device may be implemented by software and/or hardware, and may generally be integrated in a network switching device. Referring to fig. 1b, the method specifically comprises the steps of:

In this embodiment, the state of the network port of the first network device may be obtained by detecting the network port of the first network device by means of periodic polling.
S120, acquiring a state of a network port of a second network device, wherein the second network device is in communication connection with the first network device, and redundancy backup is performed between the second network device and the first network device.
The first network device and the second network device may refer to switching devices in a network system, and may be used to forward a message transmitted in a communication process between other devices in the network system. The network system may include a first network device, a second network device, a recording device, and a plurality of networks. The recording device may be configured to record all messages passing through the first network device and the second network device. Each network may include a plurality of network devices, and the networks may communicate with each other, and the communication may be implemented by the first network device and/or the second network device.
The network port may refer to an outlet where the first network device and the second network device communicate with the outside world, and the network port may include a physical port and a virtual port, which is not limited in this embodiment of the present invention. The network ports may include backup ports, traffic ports, and link ports. The backup port may refer to a port where the first network device and the second network device are respectively connected with the recording device in a communication manner, the service port may refer to a port for receiving or sending a message transmitted during communication between other devices in the network system, and the link port may refer to a port where the first network device and the second network device are connected in a communication manner.
Fig. 1C is a schematic diagram of a specific topology of a network system according to a first embodiment of the present invention, where the network system includes a network device a, a network device B, a recording device, a network C, a network D, and a network E. The network equipment A is first network equipment and comprises a backup port 5, service ports 6, 7 and 8 and a link port 1; the network device B is a second network device comprising a backup port 10, traffic ports 9, 11 and 12, and a link port 3. Specifically, the recording device is respectively in communication connection with the network device A and the network device B through ports 5 and 10; communication between networks C, D and E may be achieved through ports 6, 7 and 8 of network device A and ports 9, 11 and 12 of network device B; network device a and network device B are communicatively coupled via port 1 and port 3.
In this embodiment, in the process of the recording device recording the service packet in the network system, the first network device may acquire the network port state of the second network device.
In an optional embodiment of the present invention, the acquiring the state of the network port of the second network device may include: receiving a first LLDP (Link Layer DiscoveryProtocol ) message sent by the second network device; and determining the state of the network port of the second network equipment according to the field value matched with the reserved field in the designated frame of the first link layer discovery protocol LLDP message.
The first LLDP packet may refer to a packet generated by each network port of the second network device by opening an LLDP protocol. The designated frame may refer to a frame in the first LLDP message that can determine a current processing network port status, and typically, the designated frame may refer to a link layer discovery protocol data unit LLDPDU. The reserved field may contain identification information of the current processing network port state, typically such as Up information or Down information. The states of the network ports may include an on state and an off state. Specifically, when the information is Up, it may indicate that the current processing network port may transmit a message, that is, the current processing network port state is an on state; and in the case of Down information, it may indicate that the current processing network port may not transmit a message, i.e., the current processing network port state is in a closed state.
In this embodiment, the first network device may receive the first LLDP packet sent by the second network device, and determine the state of the port of the second network device by identifying the identification information matched with the reserved field in the specified frame of the first LLDP packet.
S130, acquiring a service message transmitted by the network system.
The service message may refer to a message generated in a process that devices under multiple networks communicate with each other through the first network device and/or the second network device.
In this embodiment, the first network device may further obtain a service packet transmitted through the own service port. Wherein, the state of the self service port is an open state.
Correspondingly, when the first network device determines that the state of at least one self service port is the on state, the first network device can acquire the service message transmitted through the self service port in the network system.
And S140, determining a forwarding mode for the service message according to the state of the network port of the first network device and the state of the network port of the second network device.
The forwarding mode may include port mirror forwarding or port mirror suspension forwarding. If the backup port state of the first network device is closed and the backup port state of the second network device is open, in this embodiment, port mirror forwarding may refer to that the first network device sends a service message of itself to the second network device, and after mirror imaging, the video recording device realizes the recording backup of the service message through the backup port of the second network device. If the backup port state of the second network device is closed, in this embodiment, the port mirror image suspension forwarding may refer to that the first network device does not send the service message of itself to the second network device for mirror image and then recording and backup.
In an optional implementation manner of this embodiment, the determining, according to the state of the network port of the second network device, a forwarding manner for the service packet may include: when the state of the backup port of the first network device is in a closed state, and the state of the link port of the first network device and the state of the service port of at least one first network device are in an open state, acquiring the state of the backup port in the second network device; judging whether the state of the backup port in the second network equipment is an opening state, if so, determining that the forwarding mode for the service message is port mirror forwarding; otherwise, determining the forwarding mode aiming at the service message as port mirror image suspension forwarding.
The closed state can be determined by the Down information, which indicates that the backup port can not transmit the message. The on state may be determined by the Up information, which indicates that the own link port and at least one own service port may transmit a message.
Specifically, when the state of the backup port of the first network device is in the closed state, and the state of the link port of the first network device and the state of the service port of at least one first network device are in the open state, the first network device may determine, according to the first LLDP message sent by the second network device, whether the state of the backup port in the second network device is in the open state, that is, whether a message can be transmitted, if so, may determine that the forwarding manner of the acquired self service message is port mirror forwarding, or may determine that the forwarding manner of the acquired self service message is port mirror suspension forwarding.
Optionally, after determining the forwarding manner for the service packet according to the state of the first network device network port and the state of the second network device network port, the method further includes:
when the forwarding mode is determined to be port mirror image forwarding, the service message is sent to the link port of the second network device through the link port of the first network device, so that the second network device mirrors the message and then sends the message to the video device through the backup port of the second network device; the video recording device is in communication connection with the first network device and the second network device.
According to the technical scheme, the state of the network port of the first network equipment is obtained; acquiring a state of a network port of a second network device in communication connection with the first network device; acquiring a service message transmitted by a network system; determining a forwarding mode aiming at the service message according to the state of the network port of the first network device and the state of the network port of the second network device, wherein the forwarding mode comprises port mirror image forwarding or port mirror image suspension forwarding, so that the problem of network resource waste caused by mirror image of message data to equipment where an unworked link is located when the prior art is used for recording and backing up the message in a network system is solved, and a novel method for controlling the message forwarding mode in the network system in real time based on the state change of the network port of the device is provided, thereby achieving the aim of saving network resources.
On the basis of the above technical solution, after detecting the network port of the first network device by means of periodic polling, obtaining the state of the network port of the first network device may further include: storing the state of the network port of the first network device in a reserved field of the second LLDP message; and sending the second LLDP message to the second network device through a link port of the second LLDP message.
The advantage of this arrangement is that the second network device can be made to determine the status of each network port of the first network device, and thus determine the forwarding manner of the service message in the second network device.
Fig. 1d is a flowchart of a specific application scenario of a method for determining a forwarding manner of a service packet according to a first embodiment of the present invention. The network device may store Up/Down information of its own network port state in a reserved field in the LLDPDU, send the Up/Down information in the form of an LLDP message to an opposite network device matched with the network device, where the opposite network device determines a backup port state of the network device according to the received LLDP message, if the Up state is the Up state, the port mirror purpose may be forwarded, and if the Down state is the Down state, the port mirror purpose may be terminated.
