Description
Technical field
The present invention relates to field of computer technology, specifically a kind of business scheduling method and device.
Background technology
With Internet high speed development, IP network needs to support various time delays and the real-time industry sensitive to delay variation
Business, and when there is sudden high non-real-time service on network, real-time service performance can receive very big influence.
In the prior art, mostly using PQ (priority query, Priority Queuing) dispatching algorithm, because PQ is dispatched
Algorithm is based on data frame, can not be interrupted in data frame transmission process.Sent for elongated bag, if one it is long
Lower-priority data frame (non-real-time service) has begun to send, while receives a high-priority data frame for being badly in need of sending
(real time business), then high-priority data frame can only wait it is to be sent, this adds increased the forward delay interval of high-priority data frame,
And lower-priority data frame is longer, the jitter performance of system is poorer.
The content of the invention
In order to solve the above problems, there is provided a kind of business scheduling method and device, can significantly lift real time business clothes
Business quality, reduces time delay, and improve delay variation performance.
The embodiments of the invention provide a kind of business scheduling method, described method includes：
S1：Transmitting terminal is that different types of service adds different control information respectively；
S2：Transmitting terminal sends the business datum with control information according to priority successively；
S3：Receiving terminal is by identifying control information, difference storage service data.
Further, step S1 specific implementation process is：Transmitting terminal obtains each business in transmit queue, and divides
The other data to each business are packaged, and add control information.
Further, in step S1, described type of service includes real time business and non-real-time service.
Further, for real time business, described control information is the K29.7 and postamble of real time traffic data frame head
K27.7 codes.
Further, for non-real-time service, described control information is the K28.0 and frame of non-real-time service data frame head
The K28.7 codes of tail.
Further, in step S2, if the priority of non-real-time service is higher than real time business, when non-real-time data not
, it is necessary to suspend non-real-time service data frame when sending real time business when having sent, after treating real time traffic data frame scheduling, after
Continuous scheduling non-real-time service data frame.
Further, step S3 specific implementation process is：When receiving terminal receives data, detection is first synchronized, works as knowledge
When not being real time traffic data frame, delimit postamble and completely receive data frame, deposit real time traffic data caching；When identification right and wrong
During real time traffic data frame, non-real-time service data buffer storage is stored in, and delimits the reception that postamble completes non-real-time service data frame.
The embodiment of the present invention additionally provides a kind of traffic scheduling device, and described device includes：
Transmitting terminal, for identifying and sending business datum；
Information embedded unit, for being embedded in different control information for different types of business datum；
Information reading unit, for reading control information in business datum, identify complete business datum；
Receiving terminal, for receiving simultaneously storage service data.
The effect provided in the content of the invention is only the effect of embodiment, rather than whole effects that invention is all, above-mentioned
A technical scheme in technical scheme has the following advantages that or beneficial effect：
1st, when transmitting terminal needs to transmit urgent high-priority data frame, by lower-priority data frame temporary suspension, by height
Priority data frame is sent to data receiver, can significantly lift quality of real-time service, reduces time delay, and improve
Delay variation performance.
2nd, data receiver carries out data frame identification and demarcation according to using K codes, and lower-priority data can be effectively ensured
The integrality of frame, prevents loss of data.
