Description of the drawings
Fig. 1 is the flow chart of present invention method；
Fig. 2 is the structural schematic diagram of apparatus of the present invention.
Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention
Embodiment be described in detail.It should be noted that in the absence of conflict, in the embodiment and embodiment in the application
Feature mutually can arbitrarily combine.
Ethernet delay shake is to have passed through buffering (buffer) caching during transmission because of Ethernet data, this
The depth cached a bit is inconsistent at different times, therefore time delay is also just different, and the difference of time delay is exactly delay variation.This reality
Apply example makes the variation range of caching depth reduce to achieve the purpose that delay of control is shaken by control.
As shown in Figure 1, the control method of the present embodiment Ethernet service air interface transmission delay variation includes：
Step 110, the Ethernet data bag forwarded from switch is decapsulated, obtained Ethernet data
It is stored in buffering；
Obtain Ethernet data after the Ethernet data bag decapsulation forwarded to switch such as exchange chip and be with
The too payload data of network service.
Step 120, it according to the relationship of the buffer water levels of Ethernet data and the critical groundwater table of setting, is sent out to switch
The instruction for controlling the transmission of switch data packet is sent, by the buffer water level controls within the scope of requiring；
Buffer water levels in text are the parameters for indicating data buffer storage depth in buffer.The higher expression of buffer water levels
The depth of data buffer storage is bigger in buffer.
In one example, critical groundwater table may include high water level and low water level, this step includes then：
If the buffer water levels of Ethernet data rise to high water level, speed limit instruction is sent (such as to switch
PAUSE frames), the transmission of instruction switch pause Ethernet data bag.Switch stops Ethernet after receiving speed limit instruction
The transmission of data packet；
If after sending limitation instruction, the buffer water level decreasings of Ethernet data are to low water level, then to switch
It sends and releases speed limit instruction, instruction switch can retransmit Ethernet data bag.Switch receives releasing speed limit and refers to
After order, the transmission of Ethernet data bag can be restarted.
For different bandwidth of air-interface, the critical groundwater table of setting is different or not exactly the same.For example, as bandwidth of air-interface compared with
Greatly, the value of high water level can be arranged larger, on the contrary then can be arranged smaller.
Step 130, after the Ethernet data being Resealed, it is scheduled be multiplexed into eat dishes without rice or wine frame in send.
In one example, be stored in buffering in Ethernet data reach it is complete one packet after can by protocol encapsulation at
Novel ether network packet, convenient for being positioned in frame of eating dishes without rice or wine.Sending device is according to the priority of various businesses and each business
Scheduling request is scheduled the data of each business, and multiplexing generates final frame of eating dishes without rice or wine.
It should be noted that each step can be with parallel processing, in addition step numbers are intended merely to convenience and attached drawing above
Control.
The speed that the present embodiment method sends switch according to buffer water levels Ethernet data bag controls, can
Buffer water level controls in a certain range, and then are controlled the delay by the Ethernet data of buffer, so as to
Reduce shake time delay.
As shown in Fig. 2, the present embodiment can be to sending device that Ethernet service air interface transmission delay variation is controlled
Including：
Unpack module 10, for being decapsulated to the Ethernet data bag forwarded from switch, obtain with
Too network data is stored in buffering.
Buffer module 20, for caching Ethernet data；
Control module 30 is used for the relationship according to the buffer water levels of Ethernet data and the critical groundwater table of setting, to friendship
Changing device send for control switch data packet transmission instruction, by the buffer water level controls setting range
It is interior.In one example, critical groundwater table includes high water level and low water level, if it is determined that the buffer water levels rise supreme water
Position then sends speed limit instruction, the transmission of instruction switch pause Ethernet data bag to switch.If it is determined that sending
After limitation instruction, the buffer water level decreasings then send to switch to low water level and release speed limit instruction, instruction exchanges dress
Ethernet data bag can be retransmitted by setting.Critical groundwater table can be accordingly arranged according to current bandwidth of air-interface, different skies
Different critical groundwater tables can be set under port band width, and when as larger such as bandwidth of air-interface, the value of high water level can be arranged larger, on the contrary
It then can be arranged smaller.
Package module 40, for the Ethernet data of caching to be re-packaged into new format by agreement.
Sending module 50, for being scheduled to packaged various businesses data, generation eats dishes without rice or wine frame and to send.
In receiving side, frame parsing module of eating dishes without rice or wine parses the frame of eating dishes without rice or wine received, the ether that will wherein Reseal
Network data packet distinguishes, and gives decapsulation module；Decapsulation module decapsulates the Ethernet data bag Resealed,
It obtains Ethernet data and is stored in cache module；Ethernet data packing in cache module is reverted to original by packetization module
Begin the format encapsulated, exports to switch.
