Embodiment Construction

[0028] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0029] figure 1 Schematic diagram of the structure of the streaming media cloud service system. The streaming media cloud includes four media edge clouds (sub-clouds) distributed in different regions A, B, C and D; in terms of network topology, in order to reduce service delay, streaming media The cloud pushes the service to each sub-cloud at the edge of the cloud. Each sub-cloud is oriented to users who use different terminal access in their respective regions; Nodes and different sub-clouds are organized and managed in a distributed manner.

[0030] In order to solve the problem of mutual transparency between the streaming media cloud and the client in the streaming media cloud service system, this paper designs a streaming media cloud transparent service device with the help of OpenFlow technology. Combine below figure 2 The princi...

Abstract

The invention discloses an OpenFlow-based streaming media cloud transparent service device, including a streaming media business management unit, a transparent service control unit and an OpenFlow network forwarding unit, which realizes the mutual transparency between the streaming media cloud and the user end, and provides Media services provide technical support for the transition to the cloud form. The content of the present invention can be used for the service transparency problem in the streaming media cloud service system, specifically including node failure, unbalanced load distribution, mobile automatic switching problems and the transparency of the client terminal to the streaming media cloud in the streaming media cloud service transparency problem The user terminal switching problem in the performance problem; the present invention can also flexibly control the forwarding path of the service flow, so as to play the role of network optimization. Therefore, the present invention can be applicable to the streaming media cloud service system of wide area, certainly also applicable to the streaming media service system of local area; And utilize the principle of the present invention, combine SDN technology and also can realize a kind of streaming media cloud transparent based on SDN service device.

Description

technical field [0001] The invention relates to the field of multimedia network communication, in particular to a device for realizing streaming media cloud transparent service based on OpenFlow technology. Background technique [0002] With the development of computer technology, the improvement of network technology and the increase in the number of network users, streaming media services have developed rapidly, such as video-on-demand services. Traditional streaming media service system is mainly composed of streaming media server, traditional distribution network and client. In order to improve the quality of streaming media services, some technologies have been successfully applied to traditional streaming media service systems, such as CDN technology, P2P technology and cluster technology, etc., but these technologies also have some limitations, such as scalability, reliability, service packaging capabilities, etc. Therefore, it is difficult to perfectly solve the ex...
