Description
Technical field
The present invention relates to the method and relevant device of the communications field, more particularly to a kind of Message processing.
Background technology
In communications network, data are transmitted in the form of message, message include heading and
Data division (being also load) beyond heading, data division is used to carry the number that transmitting terminal needs to send
It is believed that breath, heading part is used for transmission address and the destination address for carrying the message；Message is from transmission
End is to receiving terminal, it is necessary to which by one or more message forwarding equipments, message forwarding equipment is provided with route
Principle is forwarded, such as is forwarded according to shortest path first so that the shortest path that message passes through.
In network layer transport mechanism, multiple transmitting terminals can send message simultaneously, and multiple transmitting terminals utilize identical report
Literary forwarding unit resource carries out the transmission of different messages, then in whole transmission mechanism, then may have big
The message of amount is being forwarded simultaneously, is likely to result in more pending of some message forwarding equipment accumulation
Deliver newspaper text, then network congestion occur.When queue is accumulated, message forwarding equipment is by congestion mechanism to right
Queue is managed, and need to maintain less queue length, so as to reduce the queueing delay of message, and is needed
Larger queue space is maintained to absorb paroxysmal message, it is ensured that the handling capacity of queue.When queue accumulation
When length is more than certain length, the high latency and poor throughput caused can influence the effect of whole transmission mechanism
Rate and performance, in this case, message forwarding equipment can then be abandoned to segment message.
And in existing packet loss scheme, to message all in the data flow of same transmission services using flat
Deng drop mechanism.When the network is congested, multiple messages have been accumulated in the queue of message forwarding equipment, according to
The principle of queue first in first out, the message of advanced enqueue will preferentially be transferred the queue, then be entered
The message of queue may be then dropped, therefore, in network congestion, each message quilt of laggard enqueue
The probability of discarding is equality, then is likely to result in important loss of data and insignificant data reservation, from
And reduce the quality of business transmission.
The content of the invention
This application provides a kind of method of Message processing and relevant device, by preferential loss priority
Low message, so as to improve the quality of business transmission.
The application first aspect receives message there is provided a kind of method of Message processing, message forwarding equipment
Send the message set of the frame of video for the same video traffic that equipment is sent, each message in the message set
Include priority tag, and the priority that priority tag is identified is higher, then regarding in the message
The importance of frequency frame is also bigger；When the network is congested, message forwarding equipment is docked according to message control strategy
The message set received carries out packet loss, the low message of priority in preferential dropping packets set；The report
Literary control strategy can be arranged on message forwarding equipment, and message can also be sent to by SDN controllers and is turned
Send out equipment.
When the network is congested, the queue on message forwarding equipment will accumulate, when the queue length of accumulation surpasses
When crossing the threshold length that message forwarding equipment is set by dispatching algorithm, then subsequently enter the message of enqueue then
It may be dropped, in this method, when needing dropping packets, the low message of preferential loss priority, this
Sample, the accumulating amount of queue will be reduced, and team can then be entered by more including the high message of priority
Arrange and successfully forwarded, so that the high message of more priority reaches receiving terminal message receiving device,
Because the priority of message is higher, then the importance of the frame of video in the message is bigger, then receiving terminal report
The quality for the video that literary receiving device can decode that is higher.
In a kind of possible implementation, numbering letter of each message also including the message group where the message
Breath, and one group of message it is corresponding be same frame of video data message, if message forwarding equipment has abandoned one
Individual message, then other messages in the group where the message will also be abandoned by message forwarding equipment.
Because a frame of video is packaged by multiple messages, a message group is formed, when in the message group
Some message is dropped, if the message being dropped can not be resumed, then the frame of video can not be complete
Decoding, so other messages can not recover original video frame completely in receiving terminal in the message group.
So, in the case of network not congestion, message forwarding equipment can also will be other in the message group
Message carry out active discarding, so, then reduce the accumulating amount of queue in message forwarding equipment so that
Improve the handling capacity of message forwarding equipment so that message forwarding equipment can transmit more other messages.
In alternatively possible implementation, message forwarding equipment is by the message group where the message abandoned
Number information be sent to SDN controllers so that the forwarding of other messages is set on SDN control forward-paths
It is standby that active discarding is carried out to other messages in the message group.
Be the same as those described above it is similar, if being dropped a message in same group of message, then reorganization message
Possibly frame of video can not be decoded, then other messages also will be nonsensical in this group of message, SDN controls
The other message forwarding equipments of device controller are actively abandoned in reorganization message after other messages, then there is provided other
The handling capacity of router so that other message forwarding equipments can transmit more other messages.
In alternatively possible implementation, message group of each message also including place and other message groups
Between dependency information, reference the pass that the dependence is used to indicate between frame of video in message group
System；If message forwarding equipment has abandoned one group of message, then also will dependent on the other message groups of this group of message
Abandoned by message forwarding equipment.
If the message group being relied on, which is dropped, can not be sent to receiving terminal message receiving device, then depend on
Even if all messages of message in the message group of the message group all reach message receiving device, its is corresponding
Frame of video still can not be decoded, so this group of message is meaningless message group, message forwarding equipment is abandoned should
Group message, that is, improve the handling capacity of message forwarding equipment so that message forwarding equipment can transmit more
Other messages, also improve the solution bit rate of receiving terminal message receiving device.
The application second aspect is there is provided a kind of method of Message processing, and message sends equipment according to message
Labelling strategies to each its priority tag of packet labeling to be sent of frame of video in same video traffic, and
The importance of frame of video is bigger in message, and the priority that it is marked is higher；Optionally, the packet labeling
Strategy can be arranged at message and send in equipment, can also set on the application server, then be taken by application
Business device is sent to message and sends equipment；Message after mark is sent to message forwarding and set by message transmission equipment
It is standby.
Message sends equipment and message is sent to after message forwarding equipment, and message forwarding equipment then being capable of basis
The priority of message carries out forwarding control, and it can specifically include the high message of preferential forwarding priority, or
Person when the network is congested, the low message of preferential loss priority.So, then make it that more multipriority is high
Message reaches receiving terminal message receiving device, and the importance of frame of video in the higher message of priority is more
Greatly, so message receiving device can then receive the big frame of video of more importance, video is improved
The quality of business transmission.
It is multiple because a frame of video may be packaged into multiple messages in a kind of possible implementation
Message then constitutes a message group, so message sends equipment and the message institute can also be added for each message
Message group number information.
, then can be according to the report when message forwarding equipment determines to abandon messages all in a certain group of message
The number information of text group checks that all messages number information identical message is same group of message,
It will then be abandoned by message forwarding equipment, so as to improve the handling capacity of message forwarding equipment.
In alternatively possible implementation, referring-to relation is there may be between different video frame, so report
Text send equipment can also be added for each message between message group where the message and other message groups according to
The relation of relying.
After message forwarding equipment has abandoned a certain group of message, then other messages dependent on the message group
Frame of video in group will be unable to be decoded, so message forwarding equipment can then be judged by the dependence
Whether other message groups depend on the message group that this is dropped, if relying on, carry out active discarding, so,
Both the handling capacity of message forwarding equipment had been improved, receiving terminal message receiving device has been also improved and carries out frame of video

The extended field that can not be included in heading, priority tag can also be added in metadata, or
Carried in the extended field of message IP, the technology that heading extension carries information has a variety of, herein not
Do concrete restriction.Priority tag can represent by two binary systems, its table of the higher binary system of numerical value
The priority shown is higher.Such as " 00 ", " 01 ", " 11 " represent three kinds of priority respectively, wherein, " 11 "
Highest priority, the priority of " 01 " is medium, and the priority of " 00 " is minimum.
Optionally, packet labeling strategy can be arranged on message and send in equipment.
Optionally, packet labeling strategy can also be set on the application server, then will by application server
The packet labeling strategy is sent to message and sends equipment, and message sends equipment further according to the packet labeling strategy
For packet labeling priority tag.
Optionally, message, which sends equipment, to add priority tag for message, and in messages
The information of other forms is carried, such as importance field, the field can be added in metadata, should
Field can embody the importance of frame of video in the message, then read the importance by message forwarding equipment
Field, the priority tag being then converted into according to the mapping relations of packet labeling strategy.
402nd, message sends equipment and the message is sent into message forwarding equipment.
403rd, message forwarding equipment receives message and sends the message that equipment is sent.
404th, message forwarding equipment preferentially abandons the first message according to the priority tag of the message, described
First message is the low message of priority in the message.
When the network is congested, multiple messages have been accumulated in the queue of message forwarding equipment, it is advanced according to queue
The principle first gone out, the message of advanced enqueue will preferentially be transferred the queue, then enter the report of enqueue
It is literary then may be dropped.In real-time video traffic, the importance of the corresponding frame of video of different messages can
Can be different, in order to improve the transmission quality of business, the frame of video for making more importance big is transferred to message
Receiving device, then need to set message control strategy, the message control strategy can be arranged directly on message
On forwarding unit.When the network is congested, message forwarding equipment preferentially abandons excellent according to the message control strategy
The low message of first level, and the importance of the frame of video corresponding to the higher message of priority is bigger, then report
Literary forwarding unit is after the low message of loss priority, then the queue of message forwarding equipment then has more skies
Between store other messages high including priority so that the high message of more multipriority is transferred to and connect
On receiving end message receiving device.
Optionally, message forwarding equipment is received before the message that message transmission equipment is sent is received, and may be used also
First to receive the message control strategy of software defined network SDN controllers transmission, the message control strategy
For indicate dropping packets order be according to the message priority from low to high；
Optionally, the message control strategy can also be sent to message forwarding by upper layer device SDN controllers
Equipment.The message control strategy can be arranged on control strategy center, reported this by control strategy center
Literary control strategy is sent to SDN controllers；Or, the message control strategy can also be arranged on using clothes
It is engaged on device, the message control strategy is sent to control strategy center by application server, in control strategy
The heart is transmitted to SDN controllers.
Optionally, SDN controllers, which are able to detect that on all some message forwarding equipments, there occurs congestion, be
The transmission of guarantee low delay business, can send to other message forwarding equipments and abandon instruction, it is desirable to this
A little message forwarding equipments are according to the low message of priority tag active loss priority.
Based on shown in Fig. 4 embodiments, in actual applications, message sends equipment and sent by the message
Before message forwarding equipment, the number information of the message group where can also being added for the message, its
In, the data message of the same frame of video of message correspondence in one group of message.
Because a frame of video may be packaged into one or more messages, such as one frame of video is sealed
Dress up 8 messages, then 8 messages are that the data message in one group of message, this group of message is same
The information of frame of video.In order to allow message forwarding equipment to can recognize that the message group where each message, report
Text sends equipment can also add the numbering of the message group where the message in the heading of message.Specifically
, the numbering can be indicated with numeral, such as, and the priority of a message is " 01 ", its place
Message group be " 100 ".
When message forwarding equipment receives message, if the second message is identical with the number information of the first message,
It is same group of message then to represent the first message and the second message, and corresponding this group of message is same frame of video
Data message, due to having abandoned a message by message forwarding equipment in the group, then in the group
Other messages be able to not may also be decoded, then message forwarding equipment then can be by other messages in the group
Also abandoned, so, then reduce the accumulating amount of queue in message forwarding equipment so that message is forwarded
Equipment has bigger handling capacity, can accommodate more messages, reduces dropping packets when the network is congested
Quantity.
Optionally, in actual applications, transmitting terminal message transmission equipment can be to same group of message, the group
Message includes M data message, passes through forward error correction (English full name：Forward Error Correction,
English abbreviation：FEC) generate N number of checking prediction message, when and report that receiving terminal message receiving device is received
When literary sum reaches M, then the data message lost in this group of message can be replied by FEC.Therefore,
Optionally, in the case of network not congestion, message forwarding equipment is other in same group of message is abandoned
During message, the message amount that this group of message is abandoned can be first judged, if the message amount abandoned is super
Cross predetermined threshold value, then it represents that receiving terminal message receiving device can not possibly recover the data message abandoned,
So message forwarding equipment then can also discard other messages in this group of message.
Optionally, in actual applications, the numbering of message group can be recycled, such as, message group
The scope of numbering is 1-200, then after No. 200 numberings are by use, then message transmission equipment is then by under
The numbering of one group of message is labeled as 1, and the frame per second for transmitting frame of video may also detect that.So it is optional,
Message forwarding equipment can detect the number information of the message group where the second message and the in predetermined period
Whether the number information of the message group where one message is identical.The specific cycle regards according to transmission per second is how many
Depending on the length of frequency frame and numbering.
Optionally, message forwarding equipment can also send the number information of the message group of first message
Software defined network SDN controllers are given, for report of the SDN controllers according to first message
The number information of text group, which is sent, abandons instruction to other message forwarding equipments, other message forwarding equipments
For the message forwarding equipment on the forward-path of the video traffic so that other message forwarding equipments
Abandon the number information identical message with the message group of first message.
After message forwarding equipment has abandoned the first message, then in the message group where first message
Other messages may also will be unable to decoding, and other messages in the message group just may turn in other messages
