Description
Technical Field
The present invention relates to ethernet communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for collaborative aggregation of ports.
Background
Port aggregation provides a port binding technique for a switching device, i.e., a plurality of physical ports are virtualized into one port, which is also called an aggregation port. The aggregation port has the functions of improving the bandwidth, sharing the load, increasing the redundant link and the like.
Two switching devices can communicate through their respective deployed aggregation ports, and when an aggregation member port on one switching device is closed (i.e., a DOWN event occurs), the aggregation member port needs to be controlled to move out of the aggregation port on the switching device, and an opposite port corresponding to the aggregation member port is controlled to move out of the aggregation port on the other switching device; when the aggregation member port on the switching device at one end returns to normal and can receive a matched physical signal (i.e., an UP event occurs), the aggregation member port needs to be added to the aggregation port on the switching device, and the opposite end port corresponding to the aggregation member port needs to be added to the aggregation port on the switching device at the other end.
However, when a UP event occurs in a certain aggregation member port, switching devices at two ends may detect that the times of the UP event occurring in the port are not consistent, so that the switching devices at two ends cannot configure the aggregation port at the same time, and thus, a port at one end is in an aggregation state, and a port corresponding to the other end is in a non-aggregation state, which causes a connection error in a link where the port is located, and a data packet is lost.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1a is a flowchart of a port cooperative aggregation method according to an embodiment of the present invention, where this embodiment is applicable to a situation that switching devices at two ends of communication perform cooperative aggregation on respective corresponding ports in a transmission link, and the method may be executed by a port cooperative aggregation apparatus, where the apparatus may be implemented by software and/or hardware, and may generally be integrated in a source switching device, and specifically includes the following steps:
In this embodiment, when two switching devices perform communication, a switching device, which detects that a port satisfies a port re-aggregation condition in the two switching devices first, is used as a source switching device, and a switching device that performs communication with the source switching device is used as an opposite-end switching device.
Fig. 1B is a schematic diagram of a switch device, and as shown in fig. 1B, assuming that when the switch device a communicates with the switch device B, the switch device a first detects a port provided by itself, and a port meeting a port re-aggregation condition exists in the ports provided by the switch device B, the switch device a is used as a source switch device, and a corresponding switch device B is used as an opposite switch device. The switching device is a device having functions of signal switching, data forwarding and the like, such as an exchange.
In this embodiment, taking the source switching device as the switching device a as an example, when there is no aggregation port on the source switching device and the peer switching device, the source port is a port used for sending and receiving data on the source switching device, such as port a1 and port a2 in fig. 1c, and the peer port is a port used for receiving and sending data corresponding to the source port on the peer switching device, such as port B1 and port B2 in fig. 1 c. When there are aggregation ports (e.g., port a0 and port B0 in fig. 1 d) on the source switching device and the peer switching device, the source port is an independent port on the source switching device, e.g., port A3 in fig. 1d, and the peer port is a port on the peer switching device corresponding to the source port, e.g., port B3 in fig. 1 d.
In this step, optionally, the working states of each source port and the opposite port may be queried according to a preset query instruction and a port number corresponding to each port, if the working state of the source port or the opposite port is an enabled state, it is determined that the port meets a port re-aggregation condition, then the port is used as an effective port, a target port matched with the effective port is obtained, and the cooperative interaction information is constructed according to port information of the effective port and port information of the target port.
In a specific embodiment, as shown in fig. 1c, assuming that the working states of the source port a1 and the source port a2 are always enabled, when it is detected that the port re-aggregation condition is satisfied by the peer port B1 and the peer port B2, the peer port B1 and the peer port B2 are taken as valid ports, and the target ports matching the valid ports are the source port a1 and the source port a 2. Correspondingly, assuming that the working states of the opposite port B1 and the opposite port B2 are always enabled, when it is detected that the source port a1 and the source port a2 satisfy the port re-aggregation condition, the source port a1 and the source port a2 are taken as valid ports, and the target ports matching the valid ports are the opposite port B1 and the opposite port B2.
The cooperative interaction information may include port information of an effective port and port information of a target port, where the port information may include a port number, port state information, a port address, and the like. Specifically, the port address may be a Media Access Control (MAC) address of the port.
And step 120, performing at least one information interaction with the opposite terminal port through each piece of collaborative interaction information, and controlling the source terminal port and the opposite terminal port to perform collaborative re-aggregation configuration according to an information interaction result.
In this embodiment, optionally, when the valid port is a source port and the destination port is an opposite port (or the valid port is an opposite port and the destination port is a source port), the source switching device may send the cooperative interaction information to the opposite port according to an address of the opposite port, and after the opposite port receives the cooperative interaction information, the opposite port may send a confirmation message to the source port according to the source port address in the cooperative interaction information, so that when the source switching device receives the confirmation message, the source port is controlled to perform aggregation configuration, and meanwhile, the opposite port is also controlled to perform aggregation configuration.
In this embodiment, because the time consumed by the peer port to send the acknowledgment message to the source port is short, and the time when the source switching device configures the source port is almost the same as the time when the peer switching device configures the peer port, it can be ensured that the switching devices at both ends configure the aggregation port at the same time, thereby avoiding a transmission link between the switching devices from being in error, and reducing a packet loss rate of data.
In a specific embodiment, as shown in fig. 1c, it is assumed that, after receiving the acknowledgment message sent by the peer port, the source switching device may control the source ports a1 and a2 to perform aggregation configuration to generate a source aggregation port on the source switching device, and at the same time, the peer switching device also controls the peer ports B1 and B2 to perform aggregation configuration to generate a peer aggregation port on the peer switching device.
In this embodiment, after the source port and the peer port are aggregated, a transmission link between the source switching device and the peer switching device is formed. The transmission link is a transmission link between the source aggregation port and the opposite aggregation port.
The technical scheme of the embodiment of the invention constructs the cooperative interaction information pointing to the opposite terminal port by detecting whether the source port or the opposite terminal port meets the port re-aggregation condition or not, performs at least one time of information interaction with the opposite terminal port through each cooperative interaction information and controls the source port and the opposite terminal port to perform cooperative re-aggregation configuration according to the information interaction result. The technical scheme of the embodiment of the invention can ensure that the switching equipment at two ends simultaneously configures the aggregation port, avoid transmission link errors between the switching equipment and reduce the packet loss rate of data.
Example two
This embodiment is a further refinement of the above embodiment, and the same or corresponding terms as those of the above embodiment are explained, and this embodiment is not described again. Fig. 2 is a flowchart of a method for collaborative aggregation of ports provided in the second embodiment, in this embodiment, the technical solution of this embodiment may be combined with one or more methods in the solutions of the foregoing embodiments, as shown in fig. 2, the method provided in this embodiment may further include:
In an embodiment of the present invention, optionally, detecting that the source port or an opposite port in the opposite switching device satisfies the port re-aggregation condition includes: when detecting that an event of switching from closed to open occurs to a source port or an opposite port, determining that the source port or the opposite port meets a port re-aggregation condition.
The method includes the steps of querying events occurring in each port according to a preset query instruction and port numbers corresponding to the ports, and determining that the source port or the opposite port meets a port re-aggregation condition when detecting that the source port or the opposite port has an event of switching from closed (DOWN) to open (UP). Optionally, if the source port or the opposite port meets the port re-aggregation condition, the source port or the opposite port may be used as an effective port, a target port matched with the effective port is obtained, and the cooperative interaction information is constructed according to the port information of the effective port and the port information of the target port.
In this embodiment, optionally, the collaborative interaction information may include notification information and an acknowledgement message. The notification message may include port information of the valid port, port information of the target port, and a preset identifier for indicating the notification instruction. The confirmation message may include port information of the valid port, port information of the target port, and a preset identifier for indicating the confirmation instruction.

The source switching device may send a first notification message to peer port B3 based on the address of peer port B3 in the first notification message.
In this step, after receiving the first notification message, the opposite port may send, to the source port, first acknowledgement information according to an address of the source port in the first notification message, where the first acknowledgement information is used to instruct the source switching device to perform the re-aggregation configuration on the source port. When receiving the first acknowledgement information, the source port sends second acknowledgement information to the peer port, where the second acknowledgement information may be used to indicate that preparation work before the source switching device performs the re-aggregation configuration on the source port has been completed, so as to indicate that the peer switching device performs the coordinated re-aggregation configuration on the peer port.
In this embodiment, because the time consumed by the source port to send the second acknowledgement message to the peer port is short, the time when the source switching device configures the source port is almost the same as the time when the peer switching device configures the peer port, and the second acknowledgement message may also indicate that the preparation work before the source switching device performs the re-aggregation configuration on the source port has been completed, thereby ensuring that the configurations of the aggregation ports by the switching devices at the two ends are performed smoothly at the same time, and reducing errors occurring in the configuration process.
In an implementation manner of the embodiment of the present invention, performing a re-aggregation configuration on a source port includes: and aggregating the source port and the current aggregation port corresponding to the source switching equipment.
In a specific embodiment, as shown in fig. 1d, it is assumed that, after receiving the first acknowledgement message, the source switching device may control the source port A3 and the current aggregation port a0 on the source switching device to perform aggregation configuration to generate a source aggregation port on the source switching device, and at the same time, the peer switching device also controls the peer port B3 and the current aggregation port B0 on the peer switching device to perform aggregation configuration to generate a peer aggregation port on the peer switching device.
In this embodiment, after the source port and the peer port are aggregated, a transmission link between the source switching device and the peer switching device is formed. The transmission link is a transmission link between the source aggregation port and the opposite aggregation port.
In this embodiment, optionally, when the source switching device and the peer switching device detect that the source port or the peer port meets the port re-aggregation condition at the same time, the source switching device and the peer switching device may send the first notification message to the peer switching device at the same time, and control the source port and the peer port to perform cooperative re-aggregation configuration when receiving the first confirmation message sent by the peer switching device.
The technical scheme of the embodiment of the invention constructs the cooperative interaction information pointing to the opposite terminal port in the opposite terminal switching equipment by detecting whether the source port or the opposite terminal port meets the port re-aggregation condition or not, when the source port or the opposite terminal port meets the port re-aggregation condition, the cooperative interaction information can comprise notification information and confirmation information, then the first notification information is sent to the opposite terminal port, when the first confirmation information aiming at the opposite terminal port is received, the second confirmation information is sent to the opposite terminal port, and the re-aggregation configuration is carried out on the source port. The embodiment of the invention can ensure that the configuration of the switching equipment at the two ends to the aggregation port is simultaneously and smoothly carried out, avoids the transmission link between the switching equipment from generating errors and reduces the packet loss rate of data.
EXAMPLE III
This embodiment is a further refinement of the above embodiment, and the same or corresponding terms as those of the above embodiment are explained, and this embodiment is not described again. Fig. 3 is a flowchart of a cooperative aggregation method for ports provided in the third embodiment, in this embodiment, the technical solution of this embodiment may be combined with one or more methods in the solutions of the foregoing embodiments, as shown in fig. 3, the method provided in this embodiment may further include:
After the source port and the opposite port are re-aggregated, a transmission link between the source switching device and the opposite switching device is formed.
And step 320, sending first notification information to the opposite port.
In this embodiment, optionally, information interaction during the port configuration process may be performed between the source switching device and the peer switching device through a predefined data frame format, where a type information of the information interaction between the source switching device and the peer switching device is defined in the data frame format.
Specifically, the source switching device may send the first notification information to the peer port according to the data frame format, and a data frame sent by the source switching device to the peer port may include the MAC address of the source port, the MAC address of the peer port, the EtherType field, the message type, and the padding field. The EtherType field is used to specify the protocol to be applied in the data frame. The padding field may include port numbers of the source port and the peer port, port state information, and the like.
In a specific embodiment, when the source switching device sends the first notification information to the peer port, the message type is defined as 0x00, which is used to indicate that the message is a notification message.
In a specific embodiment, when the source switching device sends the second acknowledgement information to the peer port, the message type is defined as 0x01, which is used to indicate that the message is an acknowledgement message.
Wherein the second acknowledgement information is used to instruct the peer switching device to perform collaborative re-aggregation configuration on the peer port.
And 340, identifying port information included in the first confirmation information and a preset first configuration waiting duration.
In this embodiment, the first acknowledgement message includes port information that the switching devices at both ends need to configure and a preset first configuration waiting duration, and optionally, the port information and the preset first configuration waiting duration may be identified in the first acknowledgement message according to a preset delimiter.
And step 350, taking the current moment as a time starting point, and after waiting for the first configuration duration, performing re-aggregation configuration on the source port according to the port information.
In this embodiment, optionally, the second acknowledgement information includes port information that the switching devices at both ends need to configure, and a preset second configuration waiting duration, where the second configuration duration is matched with the first configuration duration. Correspondingly, after the peer port receives the second acknowledgement message, the peer switching device may use the current time as a time starting point, wait for the second configuration duration, and perform the re-aggregation configuration on the peer port according to the port information.
In this embodiment, because the switching devices at the two ends start to configure the corresponding ports after receiving the acknowledgment messages respectively, and the source switching device sends the second acknowledgment message to the peer port when receiving the first acknowledgment message, the time difference between the first configuration waiting time and the second configuration waiting time can be determined according to the time consumed by the source switching device sending the second acknowledgment message to the peer port. Specifically, assuming that the time consumed for the source switch device to send the second acknowledgement message to the peer port is 2ms, the first configured waiting duration may be set to 5ms, and the second configured waiting duration may be set to 3 ms. Therefore, the simultaneous configuration of the aggregation ports by the two-end switching equipment can be better ensured.
The technical scheme of the embodiment of the invention constructs the cooperative interaction information pointing to the opposite end port in the opposite end switching equipment by detecting whether the source port or the opposite end port meets the port re-aggregation condition or not, when the source port or the opposite end port meets the port re-aggregation condition, the cooperative interaction information can comprise notification information and confirmation information, then the first notification information is sent to the opposite end port, when the first confirmation information aiming at the opposite end port is received, the second confirmation information is sent to the opposite end port, the port information and the first configuration waiting time length included in the first confirmation information are identified, and the re-aggregation configuration is carried out on the source port according to the port information after the current time is taken as the time starting point and the first configuration waiting time length is waited. The embodiment of the invention can ensure that the switching equipment at two ends simultaneously configures the aggregation port, avoid transmission link errors between the switching equipment and reduce the packet loss rate of data.

In this embodiment, optionally, the source switching device may query the working states of each source port and the opposite port according to a preset query instruction and the port number corresponding to each port, if the working state of the source port or the opposite port is the enabled state, it is determined that the port meets the port re-aggregation condition, then the port is used as an effective port, a target port matched with the effective port is obtained, and the cooperative interaction information is constructed according to the port information of the effective port and the port information of the target port.
The cooperative interaction information may include port information of an effective port and port information of a target port, where the port information may include a port number, port state information, a port address, and the like. Specifically, the port address may be a Media Access Control (MAC) address of the port.
In this step, optionally, when the valid port is the source port and the destination port is the opposite port (or the valid port is the opposite port and the destination port is the source port), the source switching device may send the cooperative interaction information to the opposite port according to the address of the opposite port.
And step 420, performing at least one information interaction with the source port according to each piece of collaborative interaction information, and controlling the opposite port and the source port to perform collaborative re-aggregation configuration according to an information interaction result.
In this embodiment, after receiving the cooperative interaction information, the peer port may send a confirmation message to the source port according to the source port address in the cooperative interaction information, so that when the source switching device receives the confirmation message, the source port is controlled to perform aggregation configuration, and meanwhile, the peer switching device also controls the peer port to perform aggregation configuration.
In this embodiment, because the time consumed by the peer port to send the acknowledgment message to the source port is short, and the time when the source switching device configures the source port is almost the same as the time when the peer switching device configures the peer port, it can be ensured that the switching devices at both ends configure the aggregation port at the same time, thereby avoiding a transmission link between the switching devices from being in error, and reducing a packet loss rate of data.
The technical scheme of the embodiment of the invention receives at least one item of cooperative interaction information sent by source exchange equipment through the opposite terminal port, then carries out at least one information interaction with the source port according to each cooperative interaction information, and controls the opposite terminal port and the source port to carry out cooperative re-aggregation configuration according to the information interaction result. The technical scheme of the embodiment of the invention can ensure that the switching equipment at two ends simultaneously configures the aggregation port, avoid transmission link errors between the switching equipment and reduce the packet loss rate of data.

The first notification message is used for notifying the port information of the valid port to the opposite port.
In this embodiment, the confirmation message may include port information of the valid port, port information of the target port, and a preset identifier for indicating the confirmation instruction. Optionally, after receiving the first notification message, the opposite end port may send first confirmation information to the source port according to the address of the source port in the first notification message, where the first confirmation information is used to instruct the source switching device to perform the re-aggregation configuration on the source port. The peer switching device may send the first acknowledgement information to the source port according to a preset data frame format.
In this embodiment, when receiving the first acknowledgement information, the source port further sends second acknowledgement information to the peer port, where the second acknowledgement information may be used to indicate that preparation work before the source switching device performs the re-aggregation configuration on the source port is completed, so as to indicate that the peer switching device performs the coordinated re-aggregation configuration on the peer port.
In this embodiment, because the time consumed by the source port to send the second acknowledgement message to the peer port is short, the time when the source switching device configures the source port is almost the same as the time when the peer switching device configures the peer port, and the second acknowledgement message may also indicate that the preparation work before the source switching device performs the re-aggregation configuration on the source port has been completed, thereby ensuring that the configurations of the aggregation ports by the switching devices at the two ends are performed smoothly at the same time, and reducing errors occurring in the configuration process.

In this scenario, the switch device a first sends first notification information to the switch device B to notify the switch device B of port information meeting the port re-aggregation condition; after receiving the first notification message, the switching device B sends a first confirmation message to the switching device a to instruct the switching device a to perform the reaggregation configuration on the source port, and simultaneously, the switching device B also sends a second notification message to the switching device a to confirm that the switching device B starts to perform the preparation work of performing the reaggregation configuration on the peer port; after receiving the first acknowledgement message and the second notification message, the switching device a sends a second acknowledgement message to the switching device B, where the second acknowledgement message is used to indicate that preparation work before the switching device a performs the re-aggregation configuration on the source port is completed, so as to indicate that the switching device B performs the coordinated re-aggregation configuration on the peer port.
