[0016] 为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。 [0016] To make the objectives, technical solutions and advantages of the present invention will become more apparent hereinafter in conjunction with the accompanying drawings and embodiments of the present invention will be further described in detail. 应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。 It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the present invention.

[0017] 如图2所示,本发明多点优化的云技术IaaS操作系统平台100,包括注入服务器10、云传输服务器20、客户端30以及数据源40。 [0017] 2, the present invention is to optimize the multi-point cloud IaaS platform operating system 100, the server 10 includes an injection, the cloud transmission server 20, client 30 and the data source 40.

[0018] 注入服务器10,用于接收数据源40上传的流媒体数据,并将流媒体数据传输到云传输网络,该云传输网络包括多个云传输服务器20。 [0018] The injection server 10 for streaming media data source 40 receives the upload data, and transmitting streaming media data to the cloud transmission network, the transmission network comprises a plurality of cloud cloud transmission server 20.

[0019] 云传输服务器20,用于接收来自客户端30的流媒体传输请求,确定最佳上游云传输服务器,并从最佳上游云传输服务器接收流媒体数据并转发至客户端30。 [0019] Cloud transmission server 20, for receiving a request from the streaming client 30 to determine the best cloud upstream transmission server, and receiving streaming media data transmitted from the optimal cloud upstream server and forwarded to the client 30. 云传输服务器20包括路径长度限制模块21、成本测定模块22、服务器状态检测模块23以及云传输引擎24,路径长度限制模块21用于接收用户或者系统指定的最长路径;成本测定模块22用于根据云传输服务器20之间的路劲长度来确定传输成本;服务器状态检测模块23用于检测上游云传输服务器的状态,也即检测云传输服务器20的连接状态以及云传输服务器20的传输状态;云传输引擎24用于接收客户端30发来的请求,并根据路径长度限制模块21、成本测定模块22、服务器状态检测模块23发来的信息确定最佳上游云传输服务器。 Cloud server 20 includes a transmission module 21 limits the path length, the cost determination module 22, the server status detection module 23 and the maximum engine transmission path cloud 24, the path length limit module 21 is configured to receive a user or system specified; cost determination module 22 the determined transmission cost path length 20 between the cloud King transmission server; status detection module 23 for detecting a state of the upstream transport server cloud, i.e. a connection state detection server 20 the cloud transmission and cloud transmission state of the transmission server 20; cloud transport engine configured to receive a client request 24 sent by the terminal 30, and according to the path length limitation module 21, the cost determination module 22, the server status check unit 23 determines the best information sent by the upstream transport server cloud.

[0020] 客户端30,用于向云传输服务器20发送流媒体传输请求以及从云传输服务器20接收流媒体数据。 [0020] The client 30, a server 20 transmits to the cloud transmission and cloud streaming media transmission request transmitted from the server 20 receives the streaming media data.

[0021] 本发明的核心是云传输引擎24,它接受用户的要求并与其他组件进行交互,然后决定最佳的上游流媒体服务器(上游云传输服务器)。 Core [0021] The present invention is a cloud transfer engine 24 which accepts the user's requirements and interact with other components, and then determine the best streaming server upstream (upstream transmission server cloud). 路径长度限制模块21接受用户或者系统的指定而确定最长路径。 Module 21 receives the path length limitation specified user or the system to determine the longest path. 服务器到服务器的成本是由成本测定模块22完成。 Server to server cost determined by the cost of the module 22 is completed. 流媒体服务器的状态是由服务器状态检测模块23决定,每一个内容分发网络的服务器之间的连接被安装或拆除都会导致状态的更新。 Status of the streaming server module 23 is determined by detecting the state of the server, the server is connected between each of the content distribution network is installed or removed results in an update state.

[0022] 在一个实施例中,当一个新的直播开始播放流,客户端30通过附加的DNS确定第一个云传输服务器20,若该第一个云传输服务器20正在传输流媒体,则从该第一个云传输服务器20接收流媒体数据。 [0022] In one embodiment, when a new live stream starts playing, the client 30 determines that the first cloud transmission of the DNS server 20 by an additional, if the first cloud transmission 20 is transmitting streaming media server, from the first cloud server 20 receives the transmitted streaming data. 否则,云传输引擎24将确定最佳的上游云传输服务器20,云传输引擎24通过查询各种服务器状态来确定所有候选上游云传输服务器20。 Otherwise, the cloud will determine the best transport engine 24 upstream transmission server 20 the cloud, the cloud transmission by querying various server engine 24 to determine the status of all candidate cloud upstream transmission server 20. 其中,所有的候选上游云传输服务器20都在传输该媒体流。 Wherein all candidate cloud upstream transmission server 20 in transmitting the media stream.

[0023] 本发明多点优化的云技术IaaS操作系统平台的一个具体应用实施例如图3所示,在图3中,注入服务器I用于接收数据源S上传的流媒体数据,并将流媒体数据传输到云传输网络,云传输服务器SI从注入服务器I获得流媒体数据,而云传输服务器S2从云传输服务器SI获得流媒体数据,而不是从注入服务器I获得。 [0023] One particular application embodiment of the present invention, the multi-point cloud IaaS optimized operating system platform, for example, as shown in FIG. 3, in FIG. 3, I injected server for streaming media data received upload data source S, and streaming media data transmission to the transport network cloud, the cloud server SI I obtained transmission data from the streaming server injection, and the cloud transmission server S2 to obtain the streaming media data transmission from the cloud the SI server, instead of from the server injection I. 这样两条媒体传输路径是由注入服务器I至云传输服务器SI和由云传输服务器SI至云传输服务器S2。 Such two transmission paths from the injected media server I transmitted to the cloud server cloud SI and SI transmitted by the transmission server to the cloud server S2. 在云传输服务器S2到云传输服务器SI的路径长度小于云传输服务器S2到注入服务器I的路径长度的情况下,相对于图1中的现有技术,本发明的路径长度和比较小,网络传输成本更低,同时注入服务器的网络压力也较小,不影响最终用户体验。 In the case where the transmission path length of the cloud to a cloud server S2 transport server SI is less than the cloud server S2 transmitted to the server I injection path length with respect to the prior art FIG. 1, according to the present invention and the path length is relatively small, the transmission network lower cost, while injecting pressure on the network server is small, does not affect the end user experience. 尽管在图3中显示的例子仅有单一媒体流和两台流媒体服务器的简单场景,如果网络规模很大(比如数百台流媒体服务器),传输的媒体流很多(比如数千个媒体流),本发明的优化系统结构相对于现有技术显然更加节省网络成本。 Although simple scenario example shown in Figure 3 only a single media stream and two streaming media server, if the network is very large (for example, hundreds of streaming media server), a lot of transmission media stream (such as thousands of media streams ), optimization of the system structure of the present invention over the prior art is clearly more network cost savings.

[0024] 本发明每个云传输服务器20可以根据具体的媒体流的播放情况而选择合适的上游服务器,如果一个服务器上已经开始传送某个实时媒体流,则它可以向其他服务器提供转发服务。 [0024] The present invention each cloud transmission server 20 may select an appropriate upstream server according to the specific case of playing the media stream, if a server has a real-time media stream begins transmitting, it may provide a service to forward to other servers. 从而减小了传输路径长度,提高了流媒体传输效率,节省网络传输成本,避免网络传输资源传输浪费。 Thereby reducing the length of the transmission path, the streaming media transmission to improve efficiency and save network transmission costs, avoid the waste of network transmission resources for a transmission.

[0025] 如图4所示,本发明相应提供一种流媒体传输方法,其通过如图2所示的平台100实现,该方法包括:步骤S401,注入服务器接收数据源上传的流媒体数据,并将流媒体数据传输到云传输网络,该云传输网络包括多个云传输服务器。 [0025] As shown in FIG 4, the present invention provides a corresponding method of streaming media transmission, which is realized by the platform 100 shown in FIG. 2, the method comprising: step S401, the server receives streaming media data injection source upload data, and transmitting streaming data to the cloud transmission network, the transmission network comprises a plurality of cloud server cloud transmission. 本步骤通过注入服务器10及数据源40共同实现。 This step is achieved by co-injection server 10 and the data source 40.

[0026] 步骤S402,云传输服务器接收来自客户端的流媒体传输请求,确定最佳上游云传输服务器。 [0026] step S402, the transmission of the cloud server receives a request from the streaming client, the server to determine the optimal transmit upstream cloud. 本步骤通过云传输服务器20实现。 This step 20 to cloud transmission server.

[0027] 步骤S403,云传输服务器从最佳上游云传输服务器接收流媒体数据并转发至客户端。 [0027] step S403, the transmission of the cloud server cloud upstream from the optimum transport server receives streaming media data and forwarded to the client. 本步骤通过云传输服务器20实现。 This step 20 to cloud transmission server.

[0028] 优选的是,步骤S402中,确定最佳上游云传输服务器的步骤包括:云传输服务器根据用户或者系统指定的最长路径、服务器到服务器的成本以及上游云传输服务器的状态来确定最佳上游云传输服务器。 [0028] Preferably, the step S402, the step of determining the optimal cloud upstream transmission server comprising: a cloud server specifies a transmission system according to a user or the longest path, the cost and the server state of the upstream transport server cloud server to determine the most best server cloud upstream transmission. 上游云传输服务器的状态包括:云传输服务器的连接状态以及云传输服务器的传输状态。 Cloud state of the upstream transmission server comprising: a connection state of the server cloud transmission and cloud transmission state of the transmission server.

[0029] 优选的是,流媒体传输方法还包括:客户端通过附加的DNS确定第一个云传输服务器,若该第一个云传输服务器正在传输流媒体,则从该第一个云传输服务器接收流媒体数据。 [0029] Preferably, the streaming media transmission method further comprising: determining the first cloud client transport server the DNS by an additional, if the first server is a cloud transmission media transport stream, transmitted from the first server cloud receiving streaming media data.

[0030] 本发明提供了一个专为实时流媒体应用而设计的服务器选择机制,它的目的是节省传输成本,但不影响最终用户体验。 [0030] The present invention provides a mechanism for selecting a server for real-time streaming media applications designed, its purpose is to save transmission costs, but not affect the end user experience. 技术核心是通过把云传输服务器组成动态的树状,而非传统的层状结构。 The core technology is the cloud by transmitting a dynamic tree of servers, rather than the traditional layered structure. 每个云传输服务器可以根据具体的媒体流的播放情况而选择合适的上游服务器。 Each transport server cloud can be selected according to the appropriate upstream server specific media stream playing conditions. 如果一个服务器上已经开始传送某个实时媒体流,则它可以向其他服务器提供转发服务。 If a server has begun to transmit a real-time media stream, it can provide forwarding services to other servers. 在上述实施例中,为了描述方便,采用路径长度来代表传输成本,但这种简化不会影响具体的应用,因为传输成本可以同时考虑其他因素,比如地理位置等。 In the above embodiment, for convenience of description, the path length is represented using transmission costs, but this simplification will not affect the specific application, because transmission costs may be considered at the same time other factors, such as geographic location.

[0031] 综上所述,本发明通过注入服务器将数据源上传的流媒体数据传输到云传输网络,云传输网络中的云传输服务器接收来自客户端的流媒体传输请求,确定最佳上游云传输服务器;再从最佳上游云传输服务器上游的接收流媒体数据并转发至客户端。 [0031] In summary, the present invention, the cloud transmission network cloud transport streaming server receives requests from clients by implantation server uploading a data source to transmit streaming media data transmission network cloud, cloud upstream transmission to determine the best server; then receive streaming media data from the server cloud upstream of best upstream transmission and forwarded to the client. 相对于现有技术中所有的云传输服务器必须从注入服务器来获取流媒体数据的方式,本发明每个云传输服务器可以根据具体的媒体流的播放情况而选择合适的上游服务器,如果一个服务器上已经开始传送某个实时媒体流,则它可以向其他服务器提供转发服务。 All prior art cloud server must be transmitted Obtaining streaming media data from the server with respect to the injection, each transport server cloud the present invention can be selected according to the appropriate upstream server specific case of playing media streams, if a server has begun transmitting a real-time media stream, it can provide forwarding services to other servers. 从而减小了传输路径长度,提高了流媒体传输效率,节省网络传输成本,避免网络传输资源传输浪费。 Thereby reducing the length of the transmission path, the streaming media transmission to improve efficiency and save network transmission costs, avoid the waste of network transmission resources for a transmission.

[0032]当然,本发明还可有其它多种实施例,在不背离本发明精神及其实质的情况下,熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形,但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 [0032] Of course, the present invention may have a variety of other embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding modifications and variations according to the present invention, but these corresponding changes and variations should fall within the scope of the appended claims.
