Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a self-loop processing method based on a spanning tree protocol, and referring to fig. 1, fig. 1 is a flow diagram of a first embodiment of the self-loop processing method based on the spanning tree protocol.
While a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in a different order than that shown or described.
The self-loop processing method based on the spanning tree protocol comprises the following steps:
step S10, starting a spanning tree protocol of the first device port, and detecting whether the second device port has a self-loop through the spanning tree protocol.
After the first device is powered on, a spanning tree protocol of a port of the first device is started, then a port state of a port of the second device is detected through an application module of a software layer in the spanning tree protocol, and whether a self-loop exists in the port of the second device is judged.
The spanning tree protocol is a communication protocol of a data link layer in an OSI (Open System Interconnection) network model. The port status of the second device port includes the presence and absence of a self-loop. The software layer of the spanning tree protocol has a plurality of application modules, and the different modules have different functions, and the application modules include, but are not limited to, a detection application module, a receiving application module and a sending application module.
It should be noted that the self-loop circuit includes an open loop circuit and a dark loop circuit, where the open loop circuit refers to a circuit generated by connecting the device ports through solid lines, and the dark loop circuit refers to a circuit generated by a message data stream at the device ports, and the embodiment does not limit the form of the self-loop circuit.
Further, the step S10 includes:
step a, starting a spanning tree protocol of a first equipment port, and detecting whether a message data flow loop exists in a second equipment port or not through the spanning tree protocol;
b, if the message data flow loop does not exist, determining that the self-loop does not exist at the second equipment port;
and c, if the message data flow loop is detected to exist, determining that the self-loop exists at the second equipment port.
Specifically, the first device starts a spanning tree protocol of a first device port, detects whether a second device port repeatedly sends and receives the same message within a preset time through a detection application module of the spanning tree protocol, if the second device port repeatedly sends and receives the same message within the preset time, the second device port is indicated to have a message data flow loop, the first device determines that a self-loop exists at the second device port, if the second device port does not repeatedly send and receive the same message within the preset time, the second device port is indicated to not have the message data flow loop, and the first device determines that the self-loop does not exist at the second device port.
The message is a Data Unit exchanged and transmitted in the network, and the message types include, but are not limited to, a BPDU (bridge protocol Data Unit) message, an LSP (Link State PUD) message, and a SNP (Sequence Number PUD) message. The message sent from the second device port returns to the second device port in a very short time, and the message data flow is formed by the process of repeated circulation of the message at the second device port. The preset time is a millisecond time unit, which can be set according to the requirement, and this embodiment is not limited.
In this embodiment, for example, the preset time is 1 millisecond, 100 messages sent by the second device port are A1 to a100, within 1 millisecond, A1 to a50 messages in the 100 messages return to the second device port, after the second device receives the returned A1 to a50 messages, the second device sends the returned A1 to a50 messages, and the messages from A1 to a50 return to the second device port, and the process is repeated, so that A1 to a50 message data flow loop is formed.
Step S20, if it is detected that the self-loop exists, setting the state of the spanning tree protocol as a defined state, and setting the state of the first device port as a speed-limited transmission state.
And if the first equipment detects that the second equipment port has a self-loop circuit, setting the original definition state of the spanning tree protocol as a new definition state, and setting the original speed-limiting transmission state of the first equipment port as a new speed-limiting transmission state.
The defined states of the spanning tree protocol include a Discarding state, a Blocking state, a Listening state, a Learning state, and a Forwarding state. The discard state is to discard all messages of the first device port, the blocking state is to receive messages but not send messages by the first device port, the listening state is to receive and send messages by the first device port, the learning state is to receive and send messages and learn an MAC (media Access Control Address) Address, and the forwarding state is to receive and send messages by the first device port and learn the MAC Address.
Further, the step S20 includes:
and d, if the self-loop is detected to exist, setting the defined state as a discarding state, and setting the bandwidth transmission state of the first equipment port as a speed-limiting transmission state.
Specifically, if the first device detects that the second device port has a self-loop, the original definition state in the spanning tree protocol and the original bandwidth transmission state in the first device port are cancelled, the original definition state in the spanning tree protocol is set to be a discard state, the original bandwidth transmission state of the first device port is set to be a speed-limiting transmission state, and the original port flag state of the first device port is set to be a loop port flag.
The loopback port mark is prompt information indicating that the first device port detects that a self-loop is arranged at the second device port. The speed limit transmission state is a state that the data transmission speed of the hardware bandwidth in the first device port is limited within a certain range. The speed-limited transmission state is determined by the capability of the switching chip and the capability of a Central Processing Unit (CPU) of the first device, and the speed-limited transmission states of different devices are different, which is not limited in this embodiment.
In this embodiment, for example, the original defined state of the spanning tree protocol is a forwarding state, the original port flag state of the first device port is a loopback-free port flag, the original bandwidth transmission state of the first device port is 100Mbps, and when the first device detects that the second device port has a self-loop, the forwarding state is set to a discarding state, the loopback-free port flag is set to a loopback port flag, and 100Mbps is set to 30 Mbps.
Step S30, detecting a receiving state of a return packet in the first device port, and adjusting the definition state and the speed-limited transmission state according to the receiving state.
The first device detects the receiving state of the returned message in the first device port, adjusts the current definition state and the current speed limit transmission state according to the receiving state, and can switch the current definition state and the current speed limit transmission state to the original definition state and the original speed limit transmission state or continuously maintain the current definition state and the current speed limit transmission state.
The return message includes many messages, including native message and non-native message. The receiving state may be that a return message is received or that no return message is received.
Further, the step S30 includes:
step e, detecting whether the first equipment port receives the return message;
step f, if the return message is not received, adjusting the definition state to a preset definition state, and adjusting the speed-limiting transmission state to a preset bandwidth transmission state;
and g, if the return message is received, adjusting a definition state and the speed-limiting transmission state according to the message type in the return message.
Specifically, the first device detects whether the first device port receives a return message of the second device, and if the return message is not received, the first device adjusts the current definition state to a preset definition state and adjusts the current speed-limiting transmission state to a preset bandwidth transmission state. If the return message is received, judging the type of the return message, correspondingly adjusting the current definition state and the current speed limit transmission state according to the type of the return message, switching the current definition state and the current speed limit transmission state to a preset definition state and a preset bandwidth transmission state, or keeping the current definition state and the current speed limit transmission state.
The preset definition state comprises a discarding state, a listening state, a learning state and a forwarding state. The return message types include a native message and a non-native message, and the preset bandwidth transmission state is not limited to the preset definition state and the return message form in this embodiment. The preset bandwidth transmission state is determined by the capability of the switch chip and the capability of the CPU of the first device, the speed-limited transmission states of different devices are different, and this embodiment is not limited.
Further, the step g includes:
step h, if receiving the return message, detecting whether a local message sent by the first equipment port exists in the return message;
step i, if detecting that the local message does not exist in the return message, adjusting the definition state to the preset definition state, and adjusting the speed-limiting transmission state to the preset bandwidth transmission state.
Specifically, if the first device receives a return message, comparing a message port address in the return message with a port address of a first device port, if the message port address is the same as the port address of the first device port, determining that a local message sent by the first device port exists in the return message, and if the message port address is different from the port address of the first device port, determining that the local message sent by the first device port does not exist in the return message. If the local message is detected to exist in the returned message, the first device correspondingly adjusts the current definition state and the current speed limit transmission state, keeps the current definition state as a discarding state, keeps the current bandwidth transmission state of the port of the first device as a speed limit transmission state, and if the local message does not exist in the returned message, the first device correspondingly adjusts the current definition state and the current speed limit transmission state, switches the current definition state to a preset definition state, and switches the current speed limit transmission state to a preset speed limit transmission state.
The message port address format includes, but is not limited to, decimal addresses, network endian addresses, and host endian addresses. The message port address is in the same expression form as the port address of the first device port, namely the message port address is corresponding to the port address of the first device port. In this embodiment, for example, if the message port address is a decimal address, the port address of the first device port is the same as the decimal address.
Further, the step h includes:
step j, if receiving the return message, detecting whether the message port bridge in the return message is consistent with the port bridge of the first equipment port;
step k, if the port bridge of the message port is detected to be consistent with the port bridge of the first equipment port, determining that a local message sent by the first equipment port exists in the returned message;
step i, if it is detected that the port bridge of the message port is inconsistent with the port bridge of the first device port, it is determined that the local message does not exist in the return message.
Specifically, after receiving a return message, the first device determines whether key information such as a bridge root, an appointed bridge, and an appointed end in a port bridge of a port of the first device port in the return message is consistent, detects whether a root bridge of the port of the return message is consistent with a root bridge of a port bridge of the first device port, whether an appointed bridge of a port bridge in the return message is consistent with an appointed bridge of a port bridge in the first device port, and whether an appointed end of a port bridge in the return message is consistent with an appointed end of a port bridge in the first device port, determines that a local message sent by the first device port exists in the return message if the root bridge, the appointed bridge, and the appointed end of the port bridge in the return message are all consistent with the root bridge, the appointed bridge, and the appointed end of the port bridge in the first device port, and detects that the root bridge, the appointed bridge, and the appointed end of the port of the return message are all consistent with each other, Any one of the designated bridge and the designated end is not consistent with the root bridge, the designated bridge and the designated end of the port bridge in the first equipment port, and the first equipment determines that the local message sent by the first equipment port does not exist in the return message.
The invention realizes that whether a self-loop exists in the second equipment port is detected through the spanning tree protocol of the first equipment port, if the self-loop exists, the state of the spanning tree protocol is set to be a defined state, the state of the first equipment port is set to be a speed-limiting transmission state, and then the defined state and the speed-limiting transmission state are adjusted according to the receiving state of the returned message. Therefore, when the device performs message communication through the spanning tree protocol, the device port of the opposite device connected with the device is detected to be a self-loop through a software layer in the spanning tree protocol, so that the port self-loop detection is realized. If the existence of the self-loop circuit is detected, setting a definition state of a spanning tree protocol and a speed-limiting transmission state of an equipment port, limiting the receiving rate of a return message by the equipment port through the speed-limiting transmission state, discarding the return message in the self-loop circuit through the definition state when the receiving rate is exceeded, so as to reduce the number of the return messages in the self-loop circuit, and then adjusting the definition state of the spanning tree protocol and the speed-limiting transmission state of the equipment port according to the detected receiving state of the return message, so that the problem generated by the self-loop of the port is solved.
Furthermore, a second embodiment of the self-loop processing method based on the spanning tree protocol is provided.
The second embodiment of the self-loop processing method based on the spanning tree protocol is different from the first embodiment of the self-loop processing method based on the spanning tree protocol in that the self-loop processing method based on the spanning tree protocol further comprises the following steps:
m, detecting whether the port state of the second equipment port is abnormal or not at intervals of preset duration;
and n, if the port state of the second equipment port is detected to be not abnormal, performing message communication with the second equipment through the first equipment port.
Specifically, the first device detects the port state of the second device port at a preset time interval through the spanning tree protocol of the first device port, and determines whether the port state is abnormal, that is, whether a self-loop circuit exists, if the self-loop circuit exists, the steps of the first embodiment are executed, and if the self-loop circuit does not exist, the first device performs normal message communication with the second device through the first device port.
It should be noted that the preset time period may be set according to a requirement, and the embodiment is not limited. The detection may be real-time detection or timing monitoring, and this embodiment is not limited.
In this embodiment, a preset time interval is used to detect whether the port state of the port of the second device is abnormal, and if it is detected that the port state of the port of the second device is not abnormal, message communication is performed with the second device through the port of the first device. Therefore, in the process of message communication of the equipment, the port state of the first equipment port is continuously detected by the first equipment port, so that normal message communication can be carried out between the equipment in the whole process, and the efficiency of message communication of the equipment is improved.
