It should be noted that the present invention is described to the processing procedure of message with the first router, institute
State each router at least two routers identical to the processing procedure of message, no longer repeat one by one.
S103, the first router determine the congestion state of the first router.
Wherein, described congestion state can be whether congestion to occur, or, described congestion state is permissible
For there is congestion.
Specifically, described the first router judges whether content occurs congestion, may include that
If the first router buffer queue length is not less than predetermined threshold value it is determined that the first router
Congestion state is that congestion occurs；
If the first router buffer queue length is less than predetermined threshold value it is determined that the gathering around of the first router
Plug-like state is that congestion does not occur.
Wherein, described predetermined threshold value can set value according to the actual requirements, and the present invention is not carried out to this
Concrete value；It is higher that predetermined threshold value is arranged, and router is difficult to judge congestion, but through passing by one's way
May be reduced by the efficiency of device transmitting message, network performance will also decrease；It is lower that predetermined threshold value is arranged,
Router easily determines generation congestion, it is possible that there is the too early speed limit to data flow, equally may be used
The reduction of network utilization can be led to.
Preferably, described predetermined threshold value can be the 80% of buffer length.
It should be noted that foregoing description merely depict in a kind of described router of detection whether occurring
The method of congestion, is not concrete restriction.It is, of course, also possible to there be other schemes to be used for detecting router
Inside whether there is congestion, such as idle queues quantity, packet pass through delay of port etc..This
The method of congestion whether is occurred specifically not limited in the bright router for detection.
S104, the first router record in the congestion marking position of the first router in the second message
The congestion state of described the first router.
Optionally, each router arranges each self-corresponding congestion marking position particular location in messages
Can consult to determine at the beginning of communication.
Optionally, each router arranges each self-corresponding congestion marking position particular location in messages
Determination, the scheme that can adopt include but is not limited to following two schemes:
Scheme 1, can communication at the beginning of consult determine each router corresponding congestion marking position tool
Body position is arranged in order through the order of router according to message.
Exemplary it is assumed that in a message transmissions path, sequentially pass through router 1, router 2,
These three routers of router 3, can communication at the beginning of consult determine, according to message transmissions path according to
The order of the router of secondary process sets gradually each router corresponding congestion marking position, so, should
Congestion marking position in message can adopt 3bit, wherein high-order congestion marking position as router 1,
Next it is the congestion marking position of router 2, last low level is the congestion marking position of router 3.
Exemplary it is assumed that in a message transmissions path, sequentially pass through router a, router b,
These three routers of router c, can consult to determine, the corresponding mark of each router at the beginning of communication
Note sequence of positions is from low level to a high position, and so, the high position in congestion marking position is then router c
Congestion marking position, next be router b congestion marking position, low level is the congestion of router 1
Marker bit.
It should be noted that above two example is merely illustrative gathering around of each router in message
The position relationship of plug marker bit, is not the restriction to particular content and form；In actual applications,
The position relationship of the congestion marking position of each router in message can be set according to the actual requirements.
Scheme 2, can also communication at the beginning of consult determine message in each router corresponding congestion mark
The particular location of note position.
Exemplary it is assumed that in a message transmissions path, sequentially pass through router 5, router 6,
This four routers of router 7, router 8, can consult to determine each in message at the beginning of communication
The particular location of router corresponding congestion marking position is as shown in table 1:
Table 1
| Position in congestion marking position in message | Router for labelling |
| 1 | 5 |
| 2 | 8 |
| 3 | 7 |
| 4 | 6 |
So, position 1 is then the congestion marking position of router 5, position 2 then gathering around for router 8
Plug marker bit, position 3 are then the congestion marking position of router 7, position 4 is then gathering around of router 6
Plug marker bit.
It should be noted that table 1 simply describes such scheme 2 by way of example, it is not other side
The restriction being embodied as means of case 2.In actual application, can according to the actual requirements, really
That determines scheme 2 is embodied as means.
Certainly, described the first router is remembered in the congestion marking position of the first router in the second message
The congestion state of record the first router, can also realize by other means, for example, it is possible to pass through word
Token records congestion state of each router etc..The present invention is not specifically limited to this, every passes through
In the scheme of the congestion state of each router of labelling, broadly fall into protection scope of the present invention.
Further, the particular content of congestion marking can determine, the present invention is to this according to the actual requirements
Specifically do not limited.
Exemplary, when router judges itself congestion, can be in the congestion marking position of this router
Labelling " 1 ", for indicating this router congestion；And when judging that router does not have congestion, at this
Congestion marking position labelling " 0 " of router, for indicating that this router do not occur congestion.
Exemplary, when router judges itself congestion, can be by the congestion marking position of this router
It is updated to " 1 ", for indicating this router congestion；And when router judges itself non-congestion,
Can not be updated in the congestion marking position of this router, for indicating the non-congestion of this router.
Certainly, in congestion marking position, the particular content of labelling may be implemented in a variety of ways, specifically real
During applying, can determine according to the actual requirements, above-mentioned example is not the concrete restriction to this.
Exemplary it is assumed that main frame (host) a sends packet to host b, according to route letter
Breath, packet need to sequentially pass through router a, router b and reach host b.
Assume that the packet that host a sends is as shown in table 2.
Table 2
It should be noted that table 2 only example describes a packet, be not in packet
Appearance and the restriction of form.
Assume in transmitting procedure, when the packet shown in when table 2 transmits to router a, router
A determines that the congestion state of itself is that congestion has occurred, then by the congestion mark of router a in packet
Note position (highest order in current transmission direction) is updated to 1, and now packet is as shown in table 3.
Table 3
Assume in transmitting procedure, when the packet shown in when table 3 transmits to router b, router
B determines that the congestion state of itself is that congestion does not occur, then by the congestion mark of router b in packet
Note position (lowest order in current transmission direction) is not updated, and now packet is still as shown in table 3.
Therefore, the packet shown in table 3 will reach host b.
S105, the first router forward record to have gathering around of described the first router according to the first routing iinformation
Second message of plug-like state.
Specifically, described message is carried out next-hop forwarding according to the first routing iinformation by the first router
When, next-hop may be for router it is also possible to be receiving device, specific repeating process is herein not
It is described in detail again.
S106, receiving device receive the first message after described at least two routers forward.
Wherein, include the congestion state letter of described at least two routers in the first message after described forwarding
Breath.
Specifically, in the transmitting procedure of the first message, the first message is sent by sending ending equipment first,
Afterwards according to the first routing iinformation, reach receiving terminal after the forwarding of described at least two routers and set
Standby place, because each router is when E-Packeting, all right at the congestion marking position of itself in messages
The congestion state of itself has carried out labelling, therefore, after described at least two routers forward the
The jam state information of described at least two routers is included in one message.
The jam state information of described at least two routers is returned to described by s107, receiving device
Sending ending equipment.
Specifically, the jam state information of described at least two routers is returned by described receiving device
To described sending ending equipment, following two steps can be included:
Step a, generation confirm bag, and described confirmation bag is used for confirming that described receiving device has been received by
Described first message, includes the congestion state letter of described at least two routers in described confirmation bag

Comprise congestion marking position in messages, the congestion shape of the router to pass through in the transmission of registration confirmed bag
State.
Further, when message is to confirm bag, except including described at least two in described confirmation bag
The jam state information of router, can also comprise the congestion marking position of itself, with registration confirmed bag
The congestion state of the router passing through in transmission；Now, contain gathering around of two transmission directions in message
Plug marker bit.
Optionally, when including the congestion marking position of two transmission directions in message simultaneously, can adopt
Two parts of one congestion marking position are realized, it would however also be possible to employ two congestion marking positions are realized respectively,
The present invention is not specifically limited to this.
Further, when the congestion marking position including two transmission directions in message simultaneously, and adopt one
When two parts of individual congestion marking position are realized, two row of congestion marking position can be adopted real respectively
Existing.
Exemplary, table 4 illustrates to include the congestion marking of two transmission directions in a kind of message simultaneously
Position.
Table 4
Wherein, different row in congestion marking position, identifies the congestion marking position of different transmission directions.
It should be noted that table 4 simply illustrates what a kind of message included in table form
Congestion marking position, is not the concrete limit of the form of the congestion marking bit field and content that message is included
Fixed.In actual applications, the shape of congestion marking position that message includes can be determined according to the actual requirements
Formula and content, the present invention is not specifically limited to this.
Further, after s102, methods described can also include: described the first router will
The value of the router marking position in described second message adds one.
Wherein, described router marking position is used for what record passed through in the transmitting procedure of current transmission direction
