Detailed Description
In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the following description of the prior art and the technical solutions in the embodiments of the present invention with reference to the accompanying drawings is provided.
The frame device may be generally inserted into a main control board, a service board and an interface board, where the service board may also implement a forwarding function. When the frame device communicates with the peer device through link aggregation, the aggregation member port of the aggregation group may be a port of each service board.
Referring to fig. 1, for a network architecture diagram shown in this application, as shown in fig. 1, a plurality of boards are inserted into a frame-type device, where a board a, a board B, a board C, and a board D are service boards, the frame-type device communicates with an opposite-end device through link aggregation, and aggregation member ports in an aggregation group of the frame-type device are a port 1 on the board a, a port 2 on the board B, a port 3 on the board C, and a port 4 on the board D; the aggregation member ports in the aggregation group of the peer device are port 5, port 6, port 7, and port 8.
When the version of the operating system or software on the frame device is upgraded, the service board may interrupt the service and restart to complete the upgrade. In order to ensure that the flow of the frame device and the opposite-end device is not interrupted during the restart process, the ISSU technology can be generally used to upgrade each service board respectively.
Specifically, when each service board is upgraded, the aggregation member port on the service board may be closed in sequence before restarting each service board. After the aggregation member port is closed, reporting a message to a main control board of the frame type equipment, so that the main control board deletes the aggregation member port from the aggregation group according to the message. When detecting that the aggregation member port of the frame device is closed, the peer device may close a port on the peer device corresponding to the aggregation member port, and then delete the port from the local aggregation group. At this time, the boxed device may communicate with the peer device based on the other aggregation member ports.
However, after the aggregation member port is closed, the port reports a message to the main control board, and the main control board deletes the aggregation member port from the aggregation group to update the aggregation group, so that the convergence time is long, and packet loss may occur within the convergence time.
In view of this, in this embodiment of the present application, before upgrading a target service board, a frame device may send an LACP packet corresponding to a port of the target service board to an opposite end device, so that the opposite end device deletes the port corresponding to the port of the target service board from a local aggregation group according to the LACP packet, and the frame device may delete the port of the target service board from the local aggregation group according to the LACP packet, and may then switch traffic communicated with the opposite end device to other aggregation member ports in the local aggregation group. Therefore, the flow can be switched rapidly, and the problem of packet loss in the convergence time due to long convergence time after the port of the aggregation member is closed is solved.
Referring to fig. 2, which is a flowchart of a method for switching traffic of an aggregation member port shown in the present application, the method is applied to a frame device, where the frame device is docked with an opposite device through link aggregation, where an aggregation member port of the frame device is a port of each service board, and the method includes the following steps:
step 201: and sending an LACP message corresponding to a port of a target service board to the opposite terminal device, wherein the LACP message carries first information and second information, and the opposite terminal device deletes the port corresponding to the port of the target service board from a local aggregation group based on the second information of the LACP message.
Step 202: and deleting the port of the target service board from a local aggregation group based on the first information of the LACP message.
Step 203: and switching the traffic communicated with the opposite terminal equipment to other aggregation member ports in the local aggregation group.
The frame device may include a frame Switch (e.g., a deep service switching gateway), or may include a VSM device that virtualizes a plurality of frame devices based on a VSM (Virtual Switch Matrix) technology.
In this embodiment, when a frame device needs to delete a port of a target service board from a local aggregation group, an LACP message corresponding to the port of the target service board may be sent to an opposite device through the port of the target service board, where the LACP message carries first information and second information. After receiving the LACP message, the peer device may delete the port corresponding to the port of the target service board from the local aggregation group based on the second information of the LACP message.
In an embodiment shown in the above, the first information may be a first preset value of an operator key field of an LACP message, and the second information may be a second preset value of a Synchronization field in an operator state of the LACP message. When the frame device needs to delete a port of a target service board, an LACP message corresponding to the port of the target service board may be constructed, and an operator key field therein may be set to a first preset value, where the first preset value may be 0; and setting a Synchronization field in the operator state to be a second preset value, wherein the second preset value can be NO.
After receiving the LACP message, the peer device may delete the port corresponding to the port of the target service board from the local aggregation group based on the second information in the LACP message.
Specifically, after receiving the LACP message, the peer device determines, based on the operator port field of the message and the Synchronization field in the operator state, that the port of the target service board is to be deleted from the aggregation group by the frame device, and further determines, based on the partner port field of the message, a port corresponding to the port of the target service board, and deletes the port from the local aggregation group.
Taking fig. 1 as an example, before upgrading the service board a, the frame device may construct an LACP packet of the port 1, set an operator key field of the LACP packet to 0, set a Synchronization field in an operator state to NO, and then send the LACP packet to the opposite-end device. After the opposite-end device receives the LACP message, it is determined that the port 1 will be deleted from the aggregation group by the frame device based on the operator port field of the message and the Synchronization field in the operator state, and then it is determined that the port 5 corresponding to the port 1 is determined based on the partner port field of the message, and then the port 5 is deleted from the local aggregation group.
In this embodiment of the present application, after the frame device sends the LACP packet corresponding to the port of the target service board to the opposite device, the port of the target service board may be deleted from the local aggregation group based on the first information of the LACP packet.
In an embodiment shown, the first information may be a first preset value of an operator key field of the LACP message, where the first preset value may be 0. The frame device may elect a aggregation member port in a local aggregation group after periodically sending the LACP packet, and when an operator key field of the LACP packet corresponding to the port of the target service board is set to 0, the port of the target service board is no longer elected as the aggregation member port in the election process in the current period. Therefore, after the frame device sends the LACP packet carrying the first information, the port of the target service board may be deleted from the local aggregation group. For a specific election process, reference may be made to the related art, and details are not described herein.
In this embodiment of the present application, after deleting, by the frame device, the port of the target service board from the local aggregation group, the traffic communicated with the peer device may be switched to another aggregation member port in the local aggregation group.
Still taking fig. 1 as an example, after the frame device deletes the port 1 from the aggregation group, the aggregation member ports in the local aggregation group are port 2, port 3, and port 4, and the frame device may send the packet to the opposite device through the aggregation member ports. And the opposite device deletes the port 5 corresponding to the port 1 from the local aggregation group, so that the opposite device sends the data packet to the boxed device through the port 6, the port 7 and the port 8. In this case, the traffic of the boxed device communicating with the peer device is switched to other aggregation member ports in the aggregation group of the boxed device.
By the measures, after the frame type equipment sends the LACP message corresponding to the port of the target service board, the frame type equipment and the opposite terminal equipment can quickly update the aggregation member port in the aggregation group, so that the convergence time is greatly reduced, and the problem of packet loss in the convergence time is avoided.
In this embodiment of the present application, if the frame device needs to upgrade the target service board, the port of the target service board may be deleted from the local aggregation group, and after completing the traffic switching, the target service board may be upgraded.
By the aid of the method, when the frame type equipment upgrades the local service board, packet loss caused by restarting of the service board is avoided, and influence of upgrading of the service board on service is reduced.
In this embodiment of the present application, after the frame device has upgraded the target service board, an LACP packet corresponding to a port of the target service board may be sent to an opposite device, where the LACP packet carries third information and fourth information. After receiving the LACP message, the peer device may add a port corresponding to the port of the target service board to a local aggregation group based on the third information of the LACP message.
In an embodiment shown in the above, the third information may be a third preset value of an operator key field of an LACP message, and the fourth information may be a fourth preset value of a Synchronization field in an operator state of the LACP message. When the frame device needs to add the port of the target service board to the local aggregation group, an LACP message corresponding to the port of the target service board may be constructed, a third preset value of the port of the target service board is obtained through calculation based on the rate and the working mode (for example, duplex) of the port of the target service board, and then the operator key field of the LACP message is filled with the third preset value; and setting a Synchronization field in an operator state of the LACP message as a fourth preset value, wherein the fourth preset value can be YES.
It should be noted that, in the embodiment of the frame device calculating and obtaining the third preset value based on the rate and the operating mode of the port of the target service board, reference may be made to the prior art, where the third preset value is consistent with values in the operator key fields of other aggregation member ports in the local aggregation group.
After receiving the LACP message, the peer device may add a port corresponding to the port of the target service board to a local aggregation group based on the fourth information in the LACP message.
Specifically, it is determined that the port of the target service board is to be added to the aggregation group by the frame device based on the operator port field of the packet and the Synchronization field in the operator state, and then it is determined that the port corresponding to the port of the target service board is determined based on the partner port field of the packet and added to the local aggregation group.
Taking fig. 1 as an example, after the frame device finishes upgrading the service board a, it may construct an LACP packet of the port 1, calculate and obtain a third preset value based on the rate and the working mode of the port 1, fill the operator key field of the LACP packet with the third preset value, set the Synchronization field in the operator state of the LACP packet to YES, and then send the LACP packet to the opposite device. After the opposite-end device receives the LACP message, it is determined that the port 1 will be added to the aggregation group by the frame device based on the operator port field of the message and the Synchronization field in the operator state, and then it is determined that the port 5 corresponding to the port 1 is determined based on the partner port field of the message, and then the port 5 is added to the local aggregation group.
In this embodiment, after the frame device sends the LACP packet to the peer device, the port of the target service board may be added to the local aggregation group based on the third information of the LACP packet.
In an embodiment shown in the present invention, the third information may be a third preset value of an operator key field of an LACP message, where the third preset value is calculated based on a rate and a working mode of a port of the target service board. The frame device may elect a aggregation member port in a local aggregation group after periodically sending the LACP message, and when a third preset value of an operator field of the LACP message corresponding to the port of the target service board is consistent with values of operator key field values of other local ports, the port of the target service board may be elected as the aggregation member port in the election process in the current period. Therefore, after the frame device sends the LACP packet carrying the third information, the port of the target service board may be added to the local aggregation group. For a specific election process, reference may be made to the related art, and details are not described herein.
In this embodiment, after adding the port of the target service board to the local aggregation group, the frame device may allocate a traffic for communicating with the peer device to the port of the target service board.
Still taking fig. 1 as an example, after the frame device adds the port 1 to the aggregation group, the aggregation member ports in the local aggregation group are the port 1, the port 2, the port 3, and the port 4, and the frame device may send the packet to the opposite device through the aggregation member ports. And the opposite device has added the port 5 corresponding to the port 1 to the local aggregation group, so that the opposite device sends the data packet to the frame device through the port 5, the port 6, the port 7 and the port 8. In this case, the port of the target service board participates in communication between the frame device and the opposite-end device, and further, the upgraded target service board participates in communication between the frame device and the opposite-end device.
In this embodiment of the present application, when the frame device needs to update the local service boards, the local service boards may be sequentially selected as target service boards based on a preset sequence, and then the process of switching and updating the traffic of the aggregation member port is performed.
In summary, in the technical solution of the present application, the frame device may send an LACP packet corresponding to a port of a target service board to an opposite device, where the LACP packet carries first information and second information; the opposite terminal device receives the LACP message, and may delete the port corresponding to the port of the target service board from the local aggregation group based on the second information in the LACP message; the frame device may delete the port of the target service board from the local aggregation group based on the first information of the LACP packet, and then switch the traffic communicated with the opposite end device to another aggregation member port in the local aggregation group;
in the application, after the frame device sends the LACP message, the port of the target service board can be directly deleted from the aggregation group, the opposite device can delete the port corresponding to the port of the target service board from the aggregation group based on the LACP message, and the frame device and the opposite device do not need to update the aggregation group when the reported message is reported after the port is closed, so that the convergence time is greatly shortened, and the problem of packet loss in the convergence time is avoided.
