Description

Method, system, equipment and storage medium for avoiding LACP protocol timeout
Technical Field
The present application relates to the field of communications, and in particular, to a method, system, device, and storage medium for avoiding LACP protocol timeout.
Background
The Port Channel (Port Channel) currently established through the LACP (Link Aggregation Control Protocol ) periodically transmits a packet of the LACPDU on each member Port to ensure the state of the Port Channel, once the LACPDU packet sent by the opposite party is not received before three times of timeout time, the member Port will not be included in the load balancing target, and once all the member ports enter the state, the running state (open status) of the Port Channel will become down. In addition to the existing interruption of the service flow, the Port down also means that the routing table may be abnormal and may cause unnecessary routing oscillation, under the scenario of the wall-reboot, software of the upper layer management LACP protocol may be restarted, once the sending of the LACPDU message cannot be started before three times of Timeout, the opposite side may identify that the Port Channel is disconnected and discard the traffic, and regarding this problem, the scheme given in the LACP protocol is to configure the time of Timeout to be long Timeout (30 s), so that the software may restart for 90 s.
There are three problems with the scheme of changing the long timeout configuration: 1. the configuration of the timeout is a requirement transmitted by the opposite party, which represents how long the opposite party expects to receive the LLDP, and is not self-determined; 2. in the model with poor cpu capability, the time of 90s is not necessarily enough for the LACP management software to finish restarting, and the possibility of packet dropping still exists; 3. always configure a long timeout, meaning that when the peer is really out of question, the time switch also perceives this error for 90s and transfers traffic to other normally functioning member ports, the same scenario configures a short timeout for as long as 3s.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the following embodiments of the present application will be described in further detail with reference to the accompanying drawings.
It should be noted that, in the embodiments of the present application, all the expressions "first" and "second" are used to distinguish two entities with the same name but different entities or different parameters, and it is noted that the "first" and "second" are only used for convenience of expression, and should not be construed as limiting the embodiments of the present application, and the following embodiments are not described one by one.
In a first aspect of the embodiment of the present application, an embodiment of a method for avoiding LACP protocol timeout is provided. Fig. 1 is a schematic diagram of an embodiment of a method for avoiding LACP protocol timeout provided by the present application. As shown in fig. 1, the embodiment of the present application includes the following steps:
s1, in response to restarting of port channel management of a transmitting end, checking whether a wall-reboot identifier exists in a database, and in response to the existence of the wall-reboot identifier in the database, transmitting an LACPDU packet to a receiving end;
s2, responding to the receiving end to receive the LACPDU packet, and confirming whether a preset field in the LACPDU packet is zero or not;
s3, responding to the fact that a preset field in the LACPDU packet is not zero, setting a timer according to the number of seconds required by the warm-reboot operation, setting an identifier of the LACP state machine for neglecting the LACP timeout and continuously waiting for the LACPDU packet; and
and S4, in response to receiving a release packet sent by the sending end or the fact that the LACPDU packet is not received by the timer, releasing the identifier of neglecting the LACP timeout and entering a normal timeout judging mode.
PortChannel: the technology of integrating a plurality of physical ports into one logical Port to increase the logical bandwidth is that the traffic transmitted above can be balanced through a load balancing algorithm, and there are two general modes of establishing Port channels, namely static allocation and dynamic establishment through LACP protocol.
LACP is a protocol for implementing link dynamic aggregation and deaggregation based on the ieee802.3ad standard, and is a protocol commonly used in link aggregation. And the member ports in the link aggregation group, which are started with the LACP protocol, interact by sending LACPDU messages, and the two parties agree on the ports capable of sending and receiving the messages to determine the link for bearing the service flow. In addition, when the aggregation condition changes, such as a certain link fails, the LACP mode automatically adjusts the links in the aggregation group, and other available member links in the group take over the failed link to maintain load balance.
The LACP protocol has a Timeout attribute to tell the receiving end how long it has not received the LACP message Wen Jiuhui to determine that the member port is out of connection, and temporarily put the member port in a deselect state to avoid affecting traffic forwarding to the member port, where the current value may have two settings, a long Timeout (30 s) and a short Timeout (1 s), and the member port is determined to be out of connection after three times of the Timeout configuration.
Warm-reboot: in the data center, the offline of the device means that the service is interrupted, especially the affected range is far greater once the switch hosting the network is offline, and the service is interrupted once the software needs to be upgraded and modified, so, unlike the general reboot, there is a restarting technique named wall-reboot, which updates the software in such a way that the software is updated and the service interruption is avoided (because the chip is not affected) by backing up the database, restarting the kernel and upper layer software, and restoring the database.
The configuration of the long timeout in the LACP protocol is unidirectional at present, and a reverse notification mechanism does not exist, and the embodiment of the application ensures that a switch can notify the opposite side switch to temporarily suspend timeout judgment in the period of the warm-reboot by expanding the content of the LACP packet and modifying the LACP internal state machine, and ensures that a Port Channel cannot be closed in the period of the warm-reboot after the warm-reboot is finished.
Firstly, writing a wall-reboot flag (mark) in a database at a transmitting end, wherein the flag is used for identifying whether the process is restarted as a wall-reboot or a normal reboot after the process is restarted. An interrupt signal is sent to each process to tell each process that the ending program is finished, and the embodiment of the application adopts a self-defined signal SIGUSR to represent the norm reboot so as to distinguish SIGTERM signals used in normal reboot. When the singal handler knows that the single ware is a wall-reboot, the signal processor sends a request to the LACP runner, and the LACP runner immediately sends a special LACPDU packet to a Port under the Port Channel for three times, and then the flow of the original interrupt program is executed. Port channel manager (manager) will check if the warm-reboot flag exists in the database first, if so, it will send the special LACPDU packet again, and inform the butt end of the ending procedure of warm-reboot, and return to the normal LACP timeout mode.
The receiving end analyzes the LACPDU packet to determine whether a specific field in the packet is zero, wherein the non-zero represents that the opposite end is about to enter the wave-reboot, and meanwhile, the number of seconds (assumed to be Y seconds) required by the wave-reboot can be known in the packet, the receiving end can do two things at the moment, the first is to start a timer to set for Y seconds and then to set an LACP state machine to temporarily ignore LACP timeout, and the reason for setting the timer is to remind the opposite end of the state of canceling the ignored timeout after the wave-reboot failure. And then the state machine continuously waits for the LACPDU packet, wherein one condition is that the opposite party is actively transmitting the release packet after the warm-reboot is successful, and the other condition is that the LACPDU packet is not received before the Timer is reached, and the system can forcedly release and ignore the identifier of the LACP timeout and enter a normal timeout judging mode.
The LACPDU packet has a reserved field, in which a message to be transmitted is placed in a TLV format, and in the embodiment of the present application, 256 seconds (0 xFF) of ignore timeout is required before the wall-reboot, and after the wall-reboot is completed, an end packet with type 0x02 is sent. The contents contained in the LACPDU packet are as shown in table 1:
TABLE 1
The embodiment of the application can be realized on SONIC switch products at present, especially on the keepalive online of the PortChannel which is frequently used as MCLAG in the standard networking mode of a general data center, and on the basis of using the embodiment of the application, the switch can also avoid the problem of norm-reboot while having the advantage of short timeout, and can be used as a partition function with other manufacturers.
It should be noted that, the steps in the embodiments of the method for avoiding the LACP protocol timeout may be intersected, replaced, added and deleted, so that the method for avoiding the LACP protocol timeout by the reasonable permutation and combination transformation should also belong to the protection scope of the present application, and should not limit the protection scope of the present application to the embodiments.
