Problems solved by technology

Since the length and content of the actual data added to the queue changes at any time, it is difficult to predict in advance, and if the existing traffic scheduling scheme needs to accurately control the business flow of each user, the number of queues that need to be established may be large. There are 4k users, and each user has 8 streams, then the existing traffic scheduling scheme needs to set up 32k queues to realize traffic scheduling, and to perform traffic scheduling on such a large number of queues, the complexity of the implementation circuit is bound to be high , and it is difficult to achieve high-speed scheduling
However, if the complexity of the circuit is simplified as much as possible by simplifying the second, third, or fourth-level scheduling measures, then the obtained scheduling effect will hardly meet the requirements of the network.
[0007] Therefore, the problem existing in the existing traffic scheduling scheme is that the traffic scheduling based on the received data leads to high complexity of circuit implementation

Embodiment 1

[0054] Referring to FIG. 4 , FIG. 4 is a schematic diagram of traffic scheduling based on specific services in Embodiment 1 of the present invention. The traffic scheduling in this embodiment is three-level scheduling, and the reference factors for scheduling are users and specific services, total queue bandwidth, and queue priority. Since the five-level scheduling in the subsequent embodiment 2 is carried out by adding two-level scheduling on the basis of the three-level scheduling in embodiment 1, in order to correspond to embodiment 2, the reference factors in embodiment 1 and embodiment 2 are kept The numbers of the same scheduling levels are also the same. In this embodiment, it is assumed that the information flow provided by the operator includes: video flow, audio flow and data flow, wherein the specific services of the provided video flow include: 1Mb / s, 2Mb / s and 4Mb / s; The specific services include: 64k bytes / second (b / s), 128kb / s and 256kb / s; the specific services...

Embodiment 2

[0070] Referring to FIG. 6, FIG. 6 is a schematic diagram of traffic scheduling according to Embodiment 2 of the present invention. In order to provide better scheduling performance and parameters, this embodiment is based on the embodiment shown in FIG. 4 , and on the basis of the above-mentioned three-level scheduling, a third-level scheduling and a second-level scheduling are added to form a five-level scheduling optimization scheme. Wherein, since the fifth-level, fourth-level and first-level scheduling shown in FIG. 5 are the same as the scheduling of the same level numbers shown in FIG. The second level of scheduling is described in detail.

[0071] Third level scheduling:

[0072] The reference factor for scheduling at this level is the user's valid data. It can be seen from the above text description about the fourth-level scheduling that the scheduling result of the fourth-level scheduling is to provide users with the opportunity to send data by sending user IDs at ...

Abstract

The disclosed flow-schedule method in this case comprises: taking the user information of exact business in information flow as the sequence element to configure into queue of exact business, wherein, one queue matching one exact business; according to the exact business and user information in queue, allocating bandwidth for element in queue. It also discloses a flow-schedule device. This invention simplifies circuit and management work well, reduces data error, and improves schedule efficiency.

Description

technical field [0001] The invention relates to the technical field of network traffic scheduling, in particular to a traffic scheduling method and device. Background technique [0002] The rapid development of the Internet (Internet) and the ever-increasing demands of users influence each other and promote each other. Today, users' demand for communication has gradually extended from traditional low-speed services such as telephone, fax, and telegraph to high-speed broadband services such as Internet access, video telephony, and video-on-demand. Therefore, the ever-increasing network traffic and users' higher and higher requirements for service quality all put forward higher and higher requirements for the performance and quality of service (QoS) of routers as Internet core equipment. [0003] In the prior art, in order to ensure the QoS performance of the Internet, traffic scheduling (TM) technology is currently used to schedule network traffic, so as to reduce packet los...
