Description

Linkagg port switching method for stacking equipment and Linkagg-based stacking equipment
Technical Field
The invention relates to the technical field of network equipment, in particular to a Linkagg port switching method of stacking equipment and the Linkagg-based stacking equipment.
Background
The link aggregation Linkagg technique allows multiple physical interfaces to be bundled to form a single logical channel, providing enhanced performance and redundancy. When one physical interface fails, other interfaces are normally connected, and the link is not interrupted, and the Linkagg principle is as shown in fig. 8. The Stacking technology allows multiple devices to be combined together to be virtualized into a logical device, and when the master of the main communication device is powered down, the standby communication device stanby is upgraded into the master device to continue forwarding flow. By combining the Stacking technology and the Linkagg technology, the stability of the network can be greatly improved, the problems of traffic obstruction and the like caused by the abnormality of certain interfaces or certain equipment can be avoided, and the principle of combining the Linkagg technology and the Stacking technology is shown in fig. 9.
Linkagg ideally shares the same amount of traffic per physical link during normal forwarding activities. Once a physical link is broken, the table entry in the chip needs to be refreshed and the invalid port needs to be deleted, so that the traffic will be hashed again from the remaining several other physical ports. If the stack environment is not a stack environment, the self-healing technology can be used for rapidly refreshing the chip table entry, and in the stack environment, a large amount of traffic is lost when a down physical port is closed due to the fact that the self-healing technology cannot be used.
In order to solve the problem of switching Linkagg ports of stacking equipment, the prior art mainly depends on reporting a down event of a kernel port, then waiting for correct processing of the kernel, and then sequentially issuing the down event to a network service layer, an adaptation layer, an SDK and a chip, and refreshing table entries layer by layer. The process is long in time consumption, the time consumption is basically in the kernel processing process, the more ports are disconnected at the same time in linkagg, the longer the kernel processing time is, a large amount of flow can be lost, and in addition, the time consumption is also high in tedious message notification processing logic.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a typical module architecture of a stacking apparatus to which the Linkagg port switching method of the present application can be applied is first described.
For the sake of description simplicity, the stacked device is described as including a master communication device and a standby communication device standby. The main communication equipment and the standby communication equipment comprise a kernel, a network service layer, an adaptation layer, an SDK, a chip and a stack module. Wherein,
a network service layer: the device is used for processing the configuration message of the user, and mainly saves the configuration table entry of Linkagg for Linkagg service and sends the table entry to the adaptation layer;
adaptation layer: the SDK table entry is used for converting the configuration sent by the network service layer into the SDK table entry, and for the Linkagg service, the SDK table entry of the Linkagg is mainly stored and sent to the SDK;
and the main communication equipment and the standby communication equipment perform message interaction through the stack module.
In such a stack device, there may be two kinds of port closure situations, i.e., port closure of the primary communication device and port closure of the backup communication device. The following description will specifically describe how to implement the Linkagg port switching method of the stacked device in the present application when the port of the primary communication device is closed and the port of the standby communication device is closed, respectively.
Scene 1: closing member port belonging to Linkagg in standby communication equipment
Referring to fig. 2, a specific embodiment of the method for switching the Linkagg ports of the stacking apparatus at this time is described. In this embodiment, the method comprises:
s11, the adaptation layer of the standby communication device sends the received first interrupt message to the adaptation layer of the main communication device.
The first interrupt message is an interrupt message in which the port of the standby communication device is closed. Specifically, the adaptation layer of the standby communication equipment informs the stack module of the standby communication equipment of the received first interrupt message, and the stack module of the standby communication equipment sends the first interrupt message to the adaptation layer of the main communication equipment through the stack module of the main communication equipment after editing the message.
And S12, before the kernel of the primary communication equipment receives the first interrupt message, the adaptation layer of the primary communication equipment sends the first interrupt message to the SDK of the primary communication equipment and refreshes the chip table entry of the primary communication equipment.
That is, after receiving the first interrupt message, the adaptation layer of the primary communication device preferentially sends the first interrupt message to the SDK of the primary communication device and completes the refreshing of the chip table entry of the primary communication device. Before the chip table entry of the main communication equipment is refreshed, the adaptation layer of the main communication equipment does not send the first interrupt message to the kernel.
For the main communication equipment, a refresh processing link of processing messages through the kernel, informing the network service layer to process the list items of Linkagg, informing the adaptation layer, informing the SDK and the list items of the conventional chip of the chip is avoided. The SDK is directly informed and the chip table entry is refreshed through the adaptation layer, so that the refreshing processing link is shorter and is not limited by the tedious processing time consumption of the kernel.
And S13, before the kernel of the standby communication equipment receives the first interrupt message, the adaptation layer of the main communication equipment sends the first interrupt message to the SDK of the standby communication equipment.
In one embodiment, the adaptation layer of the primary communication device may send the first interrupt message to the SDK of the primary communication device and the SDK of the backup communication device simultaneously. Before this, the adaptation layer of the standby communication device does not send the first interrupt message to the kernel for processing.
And S14, the SDK of the standby communication equipment refreshes the chip table entry of the standby communication equipment according to the first interrupt message.
The SDK of the standby communication device may directly refresh the chip entry of the standby communication device according to the first interrupt message, and the process may be performed before the kernel of the standby communication device receives and processes the first interrupt message. Therefore, the chip table entries of the main communication equipment and the standby communication equipment are refreshed in advance, so that the closed ports are ensured not to be shared continuously, and the traffic loss is avoided.
When or after the adaptation layer of the main communication device sends the first interrupt message to the SDK of the main communication device and the SDK of the standby communication device, the adaptation layer of the main communication device and the adaptation layer of the standby communication device respectively refresh their entries according to the first interrupt message. After the adaptive layer of the main communication equipment refreshes the table entry of the main communication equipment, the kernel of the main communication equipment is informed to trigger the refreshing of the table entry of the network service layer of the main communication equipment; and after the adaptive layer of the standby communication equipment refreshes the self table entry, the kernel of the standby communication equipment is informed to trigger the refreshing of the network service layer table entry of the standby communication equipment.
Therefore, after the member ports belonging to the Linkagg in the standby communication equipment are closed, the stacking equipment completes the refreshing of all the table entries.
With reference to fig. 3, a specific embodiment of the method for switching Linkagg ports of the stacking apparatus according to the present application when the member ports belonging to Linkagg in the backup communication apparatus are closed from the end side of the backup communication apparatus is described below. In this embodiment, the method comprises:
s101, the adaptation layer of the standby communication equipment informs the adaptation layer of the main communication equipment of the received first interrupt message.
S102, before the kernel of the standby communication equipment receives the first interrupt message, the SDK of the standby communication equipment receives the first interrupt message sent by the adaptation layer of the main communication equipment and refreshes the chip table entry of the standby communication equipment.
S103, after the adaptation layer of the standby communication equipment refreshes the table entry of the standby communication equipment according to the first interrupt message, the adaptation layer informs the kernel of the standby communication equipment to trigger the refreshing of the table entry of the network service layer of the standby communication equipment.
With reference to fig. 4, a specific embodiment of the method for switching the Linkagg ports of the stacking apparatus according to the present application when the member ports belonging to Linkagg in the standby communication apparatus are closed will be described below. In this embodiment, the method comprises:
and S111, before the kernel of the main communication equipment receives the first interrupt message, the adaptation layer of the main communication equipment sends the first interrupt message received from the adaptation layer of the standby communication equipment to the SDK of the main communication equipment and refreshes the chip table entry of the main communication equipment.
And S112, before the kernel of the standby communication equipment receives the first interrupt message, the adaptation layer of the main communication equipment sends the first interrupt message to the SDK of the standby communication equipment so as to refresh the chip table entry of the standby communication equipment.
S113, after the adaptation layer of the main communication equipment refreshes the table entry of the adaptation layer according to the first interrupt message, the adaptation layer informs the kernel of the main communication equipment to trigger the refreshing of the table entry of the network service layer of the main communication equipment.
In the foregoing embodiment, from the perspective of cooperation between the primary communication device and the standby communication device, a detailed description has been given of a specific embodiment of the method for switching the Linkagg port of the stacking device according to the present application when the member port belonging to Linkagg in the standby communication device is closed.
Scene 2: linkagg member port closing in main communication equipment
Referring to fig. 5, a specific embodiment of the method for switching the Linkagg ports of the stacking apparatus at this time is described. In this embodiment, the method comprises:
and S21, before the kernel of the primary communication equipment receives the second interrupt message, the adaptation layer of the primary communication equipment sends the second interrupt message to the SDK of the primary communication equipment and refreshes the chip table entry of the primary communication equipment.
The second interrupt message is an interrupt message of the port closing of the primary communication device. The adaptation layer of the main communication device sends the second interrupt message to the SDK of the main communication device before sending the second interrupt message to the kernel, so that the refreshing of the chip table entry of the main communication device does not need to wait for the kernel to process the second interrupt message.
And S22, before the kernel of the standby communication equipment receives the second interrupt message, the adaptation layer of the main communication equipment sends the second interrupt message to the SDK of the standby communication equipment.
Specifically, the adaptation layer of the main communication device notifies the stack module of the main communication device of the second interrupt message, and the stack module of the main communication device edits the message and then sends the second interrupt message to the SDK of the standby communication device through the stack module of the standby communication device.
And S23, the SDK of the standby communication equipment refreshes the chip list item of the standby communication equipment according to the second interrupt message.
Similarly, the chip table entry of the standby communication equipment does not need to wait for the processing of the second interrupt message by the kernel, and the chip table entries of the main communication equipment and the standby communication equipment are refreshed in advance, so that the closed port is ensured not to be shared continuously, and the flow loss is avoided.
And at the same time or after the adaptation layer of the main communication equipment sends the second interrupt message to the SDK of the main communication equipment and the SDK of the standby communication equipment, the adaptation layer of the main communication equipment also sends the second interrupt message to the adaptation layer of the standby communication equipment, and the adaptation layer of the main communication equipment and the adaptation layer of the standby communication equipment respectively refresh the self items according to the second interrupt message. After the adaptive layer of the main communication equipment refreshes the table entry of the main communication equipment, the kernel of the main communication equipment is informed to trigger the refreshing of the network service layer table entry of the main communication equipment; and after the adaptive layer of the standby communication equipment refreshes the self table entry, the kernel of the standby communication equipment is informed to trigger the refreshing of the network service layer table entry of the standby communication equipment.
Therefore, after the member ports belonging to the Linkagg in the main communication equipment are closed, the stack equipment completes the refreshing of all the table entries.
With reference to fig. 6, a specific embodiment of a method for switching Linkagg ports of the stacking apparatus according to the present application when a member port belonging to Linkagg in a master communication apparatus is closed is described below. In this embodiment, the method comprises:
s201, before the kernel of the main communication equipment receives the second interrupt message, the adaptation layer of the main communication equipment sends the second interrupt message to the SDK of the main communication equipment and refreshes the chip table entry of the main communication equipment.
And S202, before the kernel of the standby communication equipment receives the second interrupt message, the adaptation layer of the main communication equipment sends the second interrupt message to the SDK of the standby communication equipment so as to refresh the chip table entry of the standby communication equipment.
S203, after the adaptation layer of the main communication equipment refreshes the table entry of the adaptation layer according to the second interrupt message, the adaptation layer informs the kernel of the main communication equipment to trigger the refreshing of the table entry of the network service layer of the main communication equipment.
With reference to fig. 7, a specific embodiment of a method for switching Linkagg ports of a stacking device according to the present application when a member port belonging to Linkagg in a primary communication device is closed will be described below with reference to an end side of a standby communication device. In this embodiment, the method comprises:
s211, before the kernel of the standby communication equipment receives the second interrupt message, the SDK of the standby communication equipment receives the second interrupt message sent by the main communication equipment, and refreshes the chip table entry of the standby communication equipment.
S212, the adaptation layer of the standby communication equipment receives the second interrupt message sent by the adaptation layer of the main communication equipment, and informs the kernel of the standby communication equipment of refreshing the list item of the network service layer of the standby communication equipment after refreshing the list item of the standby communication equipment according to the second interrupt message.
