Embodiment Construction

[0018] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0019] figure 1 It is a schematic diagram of an application scenario of an embodiment of the present invention. Such as figure 1 As shown, the OBT ring network in the data center includes n network nodes and one main controller. Wherein, n is an integer greater than 1, and the number of network nodes can be set as required. Among them, the main controller is responsible for centralized control and management such as bandwidth allocation. Each network node is a rack equipped with m servers in the data center (actually, the number of servers can be set as required), and each network node is configured with k transmitters. machine and k receivers, where m and k are both inte...

Abstract

The invention discloses a bandwidth scheduling method and device for associated streams in a data center. The bandwidth scheduling method comprises the following steps: a master controller selects bottleneck data streams of each associated stream according to a collected associated stream bandwidth request; the master controller allocates a transmission bandwidth which meets a first condition to each bottleneck data stream, and determines an estimated deadline of the associated stream to which each bottleneck data stream belongs according to the transmission bandwidth allocated to each bottleneck data stream; and the master controller allocates the transmission bandwidths to non-bottleneck data streams in each associated stream according to the estimated deadline of each associated stream, and when the transmission bandwidths allocated to the non-bottleneck data streams in all associated streams meet a second condition, determines the estimated deadline of each associated stream and the transmission bandwidth allocated to each data stream in each associated stream. According to the bandwidth scheduling method and device for the associated streams in the data center disclosed by the invention, the bandwidth dynamic scheduling for an all-optical network in the optical burst switching data center can be realized in combination with the associated streams of an application in the data center.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a bandwidth scheduling method and device for associated flows in a data center. Background technique [0002] Information services represented by mobile Internet and cloud computing increasingly rely on high-performance and scalable data centers. Usually, the data center carries many user-oriented applications such as web servers, file services, online games, enterprise applications, etc., and there are also computing-intensive tasks such as big data mining. These application tasks have caused a large number of concurrent communication flows between servers (between virtual machines). Special latency requirements are required to ensure upper-layer application performance. Therefore, how to design the corresponding data exchange bearer network to support various applications and complex communication modes in the data center, while providing the advantages of green...
