Description
Technical field
The present invention relates to networking technology area, particularly to a kind of port status method to set up, the selecting party of port priority
Method and device.
Background technology
Link Aggregation Control Protocol based on IEEE802.3ad standard (LACP, Link Aggregation Control
Protocol) it is a kind of agreement realizing link dynamic aggregation and depolymerize.LACP passes through Link Aggregation Control Protocol data sheet
Unit (LACPDU, Link Aggregation Control Protocol Data Unit) and opposite end interactive information.In static state
After adding member interface in the Trunk of lacp mode, these interfaces will notice the system of oneself by sending LACPDU to opposite end
Priority, system media Access Control (MAC, Media Access Control) address, interface priority, interface number and operation
The information such as key (Key).After opposite end receives these information, the information these information and its own interfaces preserved compares
Relatively, to select the interface that can be polymerized, both sides jointly using these interfaces that can be polymerized as Active Interface, and determine correspondence
Active link, then, LACP protocol state machine, after the normal transmitting-receiving of three protocol massages and consulting, carries out choosing activity
Interface, and forward data by this Active Interface chosen.
At present, when data forward, if the quality of this Active Interface respective links is the best, when such as link leads to when occurring
Obstructed situation, the Active Interface chosen is had no progeny in a link, becomes again non-selected state, particularly, if in networking being
Situation about being interconnected by transmission equipment, such as router 1 and router 2 are interconnected by transmission equipment, if transmission
Second-rate, now on router 1, physical interface does not break down, but link is the most obstructed, and now, router 1 needs
Want LACP to be detected by three message cycles, recognize when can not receive the protocol massages of this router 2 within three message cycles
For link failure, the Interface status of this link is set to non-selected state.But in the process, router 1 may proceed to this
The individual selected state that is in, but the obstructed interface of physical link E-Packets, this will cause sending three message cycles and (such as, join
Being set to during fast fast pattern is 3 seconds, is 90 seconds during slow Slow pattern) the substantial amounts of packet loss of interior appearance, thus reduce customer experience.
It addition, in existing LACP technology, also support the backup mode of N:M, i.e. for being in same link aggregation group
(Eth-Trunk), for N+M physical interface, can arrange and at most choose N number of interface to be in forwarding state, and other M are individual
Physical interface is in non-selected Status of Backups, and only certain link failure in the middle of the interface chosen, can allow and be in
The interface of Status of Backups replaces the interface of fault, enters selected state.Currently for specifically choosing which interface, which not being chosen
A little interfaces determine according to interface priority.And the priority of interface is human configuration, it is static attribute, the most true
Surely the priority choosing which interface is high, and as choosing interface, the priority of which interface is low, as backup interface.And in reality
In the application of border, owing to link exists dynamically change, it is impossible to determine which interface needs preferably according to artificial prediction, which
Interface need not preferably.
Therefore, in prior art, after link failure recovery, the interface of fault is quickly chosen again, if link matter
Amount instability, easy appearance is shaken repeatedly；And under LACP link aggregation N:M backup instances, port priority is that static state is joined
Put, it is impossible to dynamically adjust according to link actual motion quality, thus reduce the link-quality of selected state.

Additionally, receiving terminal is after receiving the LACP message carrying this delay selection information, ring to described transmitting terminal
Should the confirmation message of a described LACP message, to inform transmitting terminal, what receiving terminal had been received by that transmitting terminal sends includes prolonging
Time select information a LACP message.
S102: described transmitting terminal is receiving the confirmation message responding a described LACP message that described receiving terminal sends
Time, trigger timing, and by described transmitting terminal to the state of port of link being set to resting state；
In this S102, if transmitting terminal receives the confirmation message responding a described LACP message that receiving terminal sends,
Then start-up study timer trigger timing, and by transmitting terminal to should port (the i.e. end of the link of transmitting terminal of link
Mouthful) state be set to resting state.Wherein, this default delay value, it is that user preset is arranged, can be 50 seconds, it is also possible to
It it is 60 seconds, it is also possible to be 30 seconds etc., specifically can carry out adaptation according to practical situation.
Optionally, in this embodiment, transmitting terminal is after sending a described LACP message, if do not had in Preset Time
Have and receive the confirmation message responding a described LACP message that receiving terminal sends, then by described link corresponding on transmitting terminal
The state of port is set to non-selected state.It is to say, both sides consult, to set up link unsuccessful, or the port of receiving terminal
Abnormal etc..
It is of course also possible to be under " delay selection " state, if the LACP message sent occurs that (time-out is labeled as time-out
TRUE), or when sync mark position is FALSE, the non-normal negotiations of this port being described, now this port enters UNSELECTED shape
State, stops the time delay timing of " delay selection " timer.
S103: when the time of described time delay timing reaches to preset delay value, if described transmitting terminal to should link
Port normal, by described transmitting terminal to the state of port of link being set to selected state, and to described receiving terminal
Send the 2nd LACP information receiving described confirmation message, in order to described receiving terminal is receiving described 2nd LACP information
Time, arrange on described receiving terminal should the state of port of link be selected state.
Reach to preset on delay value and this transmitting terminal to should the port of link at the time delay timing time of delay timer
Time normal, transmitting terminal by this self to the state of port of link being set to selected state, and send to receiving terminal and receive
The 2nd LACP information to described confirmation message, in order to inform that receiving terminal can be set up and be connected to, and receiving terminal is receiving
After the 2nd LACP information that transmitting terminal sends, by receiving terminal to the state of port of link being also configured as selected state,
And then both sides can carry out data forwarding.
It is to say, when delay counter meets or exceeds default delay value, if this transmitting terminal to should link
Port normal, then remove " delay selection " labelling, the port of this transmitting terminal enters Selection Logic and selects, as
Fruit is chosen, then enter SELECTED state, to carry out data forwarding.
In the embodiment of the present invention, when link failure just recovers, the delay selection information of port is chosen in delay by transmitting terminal
It is sent to receiving terminal, in order to receiving terminal postpones to choose the port of this link, and is reaching default delay value and this transmitting terminal
To should the port of link normal time, reinform receiving terminal and choose the port of this link, carry out the forwarding of data.Namely
Saying, the embodiment of the present invention has just been recovered at link and before non-complete stability, has chosen port by time delay, reduces link and repeatedly shakes
Probability, improve link-quality.
Refer to the flow chart of the method to set up of a kind of port status that Fig. 2, Fig. 2 provide for the embodiment of the present invention, described
Method includes:
S201: when link failure recovery, the first Link Aggregation Control Protocol LACP that receiving terminal receiving end/sending end sends
Message, a described LACP message includes: delay selection information.
Wherein, described delay selection information is used for illustrating to postpone to choose the information of port；Described delay selection information is permissible
It is added in the reservation Reserved field of a described LACP message.
When link failure recovery, if receiving terminal receive transmitting terminal send with the first of delay selection information
LACP message, then illustrate, receiving terminal to should the port of link be normal condition.
S202: described receiving terminal to described transmitting terminal send respond a described LACP message confirmation message, and according to
It is resting state that described delay selection information arranges the state of the port of respective links on described receiving terminal；
Receiving terminal is after receiving a LACP message, and the confirmation sending the described LACP message of response to transmitting terminal disappears
Breath, this confirmation message is used for informing transmitting terminal, and this receiving terminal have received a LACP message.Then, receiving terminal by self
To the state of port of link being set to resting state, and not it is set to choose shape by the state of the port of this link
State.Now, the state of the two ends port of this link is in resting state.
S203: described receiving terminal receives the 2nd LACP information responding described confirmation message that described transmitting terminal sends；
It is to say, after transmitting terminal receives described confirmation message, be considered as receiving terminal by the port of this link
State is set to resting state, with start-up study timer trigger timing, and until (i.e. can reach at the end of delay time
To this default delay time value) on this transmitting terminal to should the port of link normal, transmitting terminal sends to receiving terminal and receives institute
State the 2nd LACP information confirming message, in order to inform receiving terminal, can by receiving terminal to should the shape of port of link
State is set to selected state.

Mouthful, reduce the probability that link shakes repeatedly, improve link-quality.
At the backup mode of existing N:M, i.e. for being in N+M thing of same link aggregation group (Eth-Trunk)
For reason port, can arrange and at most choose N number of port to be in forwarding state, and other M physical port is in and does not chooses
Status of Backups, only in the middle of the port chosen, there is link failure in certain, and the port being in Status of Backups can be allowed to replace event
The port of barrier, enters selected state.And in prior art, for specifically choosing which port, not choose which port be root
Determine according to port priority.Port priority is currently human configuration, is static attribute, is equivalent to artificial determining
Which Port Priority selects, and which port is as backup.And in actual applications, port priority seldom enters when existing network is applied
Row configuration, often uses its default value, and reason is that link often exists dynamic, it is impossible to by which port of artificial prediction needed
Wanting preferably, which bad choosing, this makes LACP when existing network is applied, it is impossible to automatically select the link of better quality.
And based on this, embodiments provide the system of selection of a kind of port priority, its flow chart such as Fig. 3 institute
Show, in this embodiment, on the basis of the interface priority (being referred to as port priority) of user's static configuration, foundation
The link informations such as port Down event, the delay variation of the duration of link down, even link, packet loss, enter port priority
Mobile state adjusts, and such as every Down once reduces 100 (recovering 50 during port UP), often interrupts within 1 minute, reducing 10 (every normal communications
Within 1 hour, recover 10).The port priority of link-quality difference can be allowed dynamically to be reduced by this means, thus select at port
It is in a disadvantageous position in selecting and avoids choosing such that it is able to ensure that the link-quality automatically choosing link is the most more preferable.Described method
