Abstract

The invention provides a traffic scheduling method and system based on a time window. The traffic scheduling method based on the time window comprises the steps of: receiving a data transmission service request, and, according to the network resource data of a data centre, pre-distributing network resources needing to be used by the data transmission service request through a K-way shortest path algorithm, so that a pre-distribution result is obtained; according to the pre-distribution result, performing optical layer reconstruction on the network of the data centre, so that the topology of adata transmission link in the data transmission service at this time is obtained; according to the topology of the data transmission link, distributing service data in the current time slot in the data transmission service, and calculating the remaining resources in the topology of the data transmission link in the data transmission service at this time in the current time slot; and, if the fact that the remaining resources exist in the data transmission service at this time in the current time slot is obtained by calculation, distributing to-be-transmitted data distributed to the subsequent time slot in the data transmission service request to the current time slot, so that transmission is carried out. By means of the method provided in the invention, the wide area network resource utilization rate between data centres is increased.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of wide area networks, and in particular to a method and system for traffic scheduling based on a time window. Background technique [0002] With the rapid development of the Internet and the emergence of new applications, the service guarantee for the large-bandwidth transmission of the wide area network between data centers has become more and more important. The wide area network between data centers is a key part of online service providers. In this network, traffic has obvious distinguishing characteristics. One type is user-oriented high-priority interactive traffic, which requires strict delays, but does not account for traffic. Large; One type belongs to large-capacity transmission traffic, such as massive business data synchronization, etc., which requires long transmission time and high throughput. Although it is not sensitive to delay, a large part of it has a time limit, that...
