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.
First embodiment
Fig. 1 is a schematic flowchart of a communication method based on a dual link management interface according to a first embodiment of the present application. In fig. 1, the communication method based on the dual link management interface includes the following steps:
in step 140, the management port is in a fault state.
Specifically, the management ports of the master device and the slave device report their normal state (UP) or fault state (DOWN) on their respective devices through interrupts, and summarize through Inter-Process Communication (IPC) messages. According to the reporting conditions of the main equipment and the standby equipment, the position information (the equipment ID) of a main management port corresponding to the main equipment and the position information (the equipment ID) of a standby management port corresponding to the standby equipment and the state information (UP/DOWN) are obtained.
And judging whether a management port in a normal state exists in the main management port and the standby management port according to the acquired port state, and if so, selecting one management port in the normal state as a logic management port to process communication data.
Optionally, in this embodiment, after acquiring port states of a main management port and a standby management port corresponding to the main device and the standby device, the method further includes:
and reporting the state of the management port to an upper layer.
Specifically, the rule for reporting the status of the management port is as follows: if the states of the management ports of the main device and the standby device are both DOWN, the state of the management port is considered to be DOWN, and if any one of the states of the main management port and the standby management port is UP, the state of the management port is considered to be UP, that is, for the upper layer, the two management ports are virtualized to be a logic management port. And constructing IPC message to send to upper layer to inform the management interface state. As shown in fig. 2, for the structure of reporting a message, the reported message content includes: a master management port state, a standby management port state, a master device ID, and a standby device ID.
Optionally, as shown in fig. 3, the step 130 specifically includes the following steps:
Specifically, when the physical states of the main device and the standby device management port are both UP states, the main device management port sends the received message to a Central Processing Unit (CPU) for Processing, and sends the message to the outside normally. If the standby device receives the message, the standby device does not perform any processing on the message and does not send the message to the outside. And the switching device in the network learns the Media Access Control (MAC) address exit port of the management port as the port (a) connected to the management port of the master device.
When the state of the main management port is DOWN, the message cannot be received, the main equipment and the standby equipment record the current state, and the MAC outlet end is switched from the port a of the main equipment management port to the port b of the standby equipment management port. Because the state of the main management port is DOWN, the MAC table entry on the switching equipment in the network is deleted.
Optionally, the IP Address and the MAC Address of the main/standby management port are set to be the same Address, so that for the switching device in the network, an Address Resolution Protocol (ARP) entry does not need to be refreshed after the state of the main management port is DOWN, thereby ensuring fast link switching.
Optionally, as shown in fig. 4, when the primary management port is in a failure state and receives a message, the method further includes:
and 430, sending the analyzed message to a processor of the main equipment for processing.
Specifically, after receiving the control message, the standby management port sends the control message to the main device through the stack port by the IPC message, so that the main device analyzes the message received by the standby management port, and then sends the analyzed message to the CPU of the main device for processing, thereby shielding the event of the main management port DOWN from the upper layer.
Optionally, as shown in fig. 5, after step 430, the method further includes:
Specifically, the broadcast control message is switched to the message of the standby device to the switching device, and the MAC information is updated through the response message, so that all the subsequent messages are switched to the link where the standby device management port is located. As shown in fig. 6, the MAC update information of the switching device having a different connection relationship with the standby device is different, and the MAC update information is specifically implemented in the following manner:
Specifically, a message is sent through the standby management port of the standby device, whether the switching device is directly connected with the standby device is judged according to a corresponding message of the switching device, if the switching device is directly connected with the standby device, the switching device updates an MAC address table of the directly connected switching device after receiving the message, and switches an address output port from a port a connected with the main device management port to a port b of the standby device management port compared with the MAC address table under a normal condition. If the switching device is not directly connected with the standby device, the MAC table entry of the switching device is not changed.
Optionally, as shown in fig. 7, the method further includes the following steps:
When the master management port is in a normal state and the standby device receives a message, the method further comprises:
and the closing message is uploaded and sent through an IPC message, so that the standby equipment does not process the received control message any more.
Specifically, because the received messages need to be sent to the CPU of the main device through the IPC message when the communication is performed using the management port of the standby device, the IPC message is increased, and when the flow of the control message is large, congestion may be caused to the original inter-board communication between the stacked devices, so that the message needs to be switched back to the main link after the main link is recovered. When detecting that the state of the main management port is restored to UP, broadcasting a message for controlling message switching to the main device to the switching device, and judging whether the switching device is directly connected with the main device, if the switching device is directly connected with the main device, on the main device, because the standby management port is always in the UP state, an MAC table item on the directly connected switching device cannot be updated, the main device management port needs to actively send a message to update the MAC table item, so that an output port corresponding to the MAC table item of the stacking system management port on the switching device directly connected with the main device is transferred to a port a of the main device management port through a port b, and an uplink Software Defined Network (SDN) control flow can be sent to the device through a port a. After the standby equipment receives the state information, the closing message is sent and sent through the IPC information, the received control message is not processed any more, and the SDN control flow is completely switched to the main equipment management port. If the switching device is not directly connected with the main device, the MAC table entry of the switching device is kept unchanged.
In the communication method based on the dual-link management port of this embodiment, port states of a main management port and a standby management port corresponding to the main device and the standby device are obtained, and according to the port states, when it is determined that a management port in a normal state exists in the main management port and the standby management port, a management port in a normal state is selected from the main management port and the standby management port as a logic management port to process communication data. The invention uses the management port on the standby device which is not used in the stacking system as the backup of the management port of the main device, and when the main link fails, the standby device management port can be quickly and effectively switched to so as to ensure that the control plane is not disconnected.

and reporting the state of the management port to an upper layer.
Specifically, the rule for reporting the status of the management port is as follows: if the states of the management ports of the main device and the standby device are both DOWN, the state of the management port is considered to be DOWN, and if any one of the states of the main management port and the standby management port is UP, the state of the management port is considered to be UP, that is, for the upper layer, the two management ports are virtualized to be a logic management port. And constructing IPC message to send to upper layer to inform the management interface state. As shown in fig. 2, for the structure of reporting a message, the reported message content includes: a master management port state, a standby management port state, a master device ID, and a standby device ID.
The determining module 920 is further configured to determine whether the main management port is in a normal state or a fault state; if the status is normal, the management port selection module 930 selects the main management port as a logic management port, and if the status is failure, the management port selection module 930 selects the standby management port as a logic management port;

Specifically, when the physical states of the main device and the standby device management port are both UP states, the main device management port sends the received message to a Central Processing Unit (CPU) for Processing, and sends the message to the outside normally. If the standby device receives the message, the standby device does not perform any processing on the message and does not send the message to the outside. And the switching device in the network learns the Media Access Control (MAC) address exit port of the management port as the port (a) connected to the management port of the master device.
When the state of the main management port is DOWN, the message cannot be received, the main equipment and the standby equipment record the current state, and the MAC outlet end is switched from the port a of the main equipment management port to the port b of the standby equipment management port. Because the state of the main management port is DOWN, the MAC table entry on the switching equipment in the network is deleted.
Optionally, the IP Address and the MAC Address of the main/standby management port are set to be the same Address, so that for the switching device in the network, an Address Resolution Protocol (ARP) entry does not need to be refreshed after the state of the main management port is DOWN, thereby ensuring fast link switching.

A broadcasting module 970, configured to broadcast, to the switching device, a message for controlling the message to be switched to the standby device;
a receiving module 980, configured to receive the response message of the switching device.
Specifically, the broadcast module 970 broadcasts a message for controlling switching of the message to the standby device to the switching device, and updates the MAC information through the response message received by the receiving module 980, so that all the following messages are switched to the link where the standby device management port is located. The switching device with different connection relation with the standby device has different MAC updating information, and is specifically realized by the following modes:

Specifically, because the received messages need to be sent to the CPU of the main device through the IPC message when the communication is performed using the management port of the standby device, the IPC message is increased, and when the flow of the control message is large, congestion may be caused to the original inter-board communication between the stacked devices, so that the message needs to be switched back to the main link after the main link is recovered. When the obtaining module 910 detects that the state of the main management port is restored to UP, a message for controlling switching of a message to the main device is broadcast to the switching device, and the determining module 920 determines whether the switching device is directly connected to the main device, if the switching device is directly connected to the main device, because the standby management port is always in the UP state on the main device, an MAC table entry on the directly connected switching device is not updated, and the main device management port needs to actively send a message to update the MAC table entry, so that an output port corresponding to an MAC table entry of a stacked system management port on the switching device directly connected to the main device is migrated from a port b connected to the standby device management port to a port a connected to the main device management port, and an uplink Software Defined Network (SDN) control stream can be sent to the device through an a port.
