Description

一种直播视频的播放方法、装置及系统 技术领域
本发明实施例涉及计算机技术领域,尤其涉及一种直播视频的播放方法、装置及系统。
背景技术
内容分发网络,即CDN,全称为Content Delivery Network。其目的是通过在现有的Internet中增加一层新的网络架构,将网站的内容发布到最接近客户端的网络"边缘",使用户可以就近取得所需的内容,解决Internet网络拥塞状况,提高用户访问网站的响应速度。CDN网络架构主要由两大部分,分为中心和边缘两部分,中心指CDN网管中心和DNS重定向解析中心,负责全局负载均衡,设备系统安装在管理中心机房,边缘主要指异地节点,CDN分发的载体,主要由高速缓存Cache和负载均衡器等组成。
视频直播是指利用互联网及流媒体技术进行直播,视频因融合了图像、文字、声音等丰富元素,声形并茂,效果极佳,逐渐成为互联网的主流表达方式。视频通过真实、生动的传播,营造出强烈的现场感,吸引眼球,达成印象深刻、记忆持久的传播效果。目前,通过CDN网络播放直播视频时,一般是由观看用户提出请求,通过边缘服务器处理该请求,并根据该边缘服务器配置的下载路径从直播平台上获取直播视频的数据并发送给用户所在的客户端,以供网友在线直播观看。由于直播视频所要求的实时性较高,因此,对于视频播放路径的数据传输性有较高的要求,在现有的直播视频播放技术中,对于播放路径的选择主要是由边缘服务器根据本地配置的固定路径进行直播视频的下载与播放。由于播放路径的选择相对单一、固定,当传输路径中的某个节点出现网络故障时,要避开故障节点就需要人工修改边缘服务器中的播放路径的配置规则或配置脚本。显然,这种方式并不适合对时效性要求较高的直播视频数据进行下载与播放。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例提供了一种直播视频的播放方法,如图1所示,该方法应用于CDN系统中的边缘服务器,具体步骤包括:
101、接收观看直播视频客户端的播放请求。
用户要观看直播视频需要在页面中选中所要观看的视频连接,即向服务器发送观看视频的播放请求,而接受播放请求的服务器在CDN系统中被称为边缘服务器,该边缘服务器是CDN系统面向用户的窗口,根据系统的设置方式,不同地区或不同网络的用户都会有与之对应的一台或多台边缘服务器为其服务,因此,边缘服务器所服务的对象相对固定,其与用户所在客户端的数据传输性能也较高。在用户有多台边缘服务器可供选择时,一般是选择负载最轻的一台发送播放请求。
102、将播放请求发送至控制中心。
当边缘服务器接收到客户端的播放请求后,会将该播放请求发送给控制中心处理。由控制中心根据当前网络的数据传输情况来配置最优的数据下载路径并返回给边缘服务器。其中,本发明实施例中的控制中心可是位于CDN系统中继设备层的服务器,能够监控CDN系统中所有节点服务器的数据传输状态,以此判断各个节点服务器当前的工作状态以及负载情况。相对于现有的在边缘服务器的本地为播放请求配置数据下载路径的方式,本发明实施例能够动态的配置路径信息,将当前网络中的故障节点避开。同时,边缘服务器由于不再处理配置数据下载路径的操作,可以将节省出的处理资源用于处理其他用户的操作,如接收用户上传的直播视频数据或者是其他用户的播放请求等。从而提高了该边缘服务器的处理效率。
103、接收控制中心返回的数据下载路径信息。
控制中心将数据下载路径信息作为播放请求的相应信息反馈给边缘服务器。该下载路径信息中的路径是根据控制中心中预置的路径配置策略实时计算得到的由存储有直播视频数据的服务器到边缘服务器的一条数据传输路径。该路径由CDN系统中的多个节点服务器组成,控制中心通过预置策略选出一条传输效率最高,且距离较短的传输路径,以提高用户观看直播视频的流畅性。
104、根据数据下载路径信息向直播平台获取播放请求对应的直播视频数据。
边缘服务器在得到数据下载路径信息后,会将用户的播放请求按照配置好的路径再发送到存储有该直播视频数据的服务器中,并由该服务器将直播视频数据按照原路径发送给边缘服务器。
进一步的,也可以由控制中心向存储有该直播视频数据的服务器发送播放请求和数据下载路径信息,并由该服务器根据配置的路径直接将对应的直播视频数据发送至边缘服务器。
105、将直播视频数据发送至客户端。
边缘服务器将得到的直播视频数据发送给客户端以响应该客户端所发送的播放请求。客户端根据接收到的数据播放直播视频。
与上述方法相对应地,本发明实施例还提供了一种直播视频的播放方法, 如图2所示,该方法应用于CDN系统中的控制中心,具体步骤包括:
201、接收边缘服务器发送的直播视频播放请求。
本发明实施例中的控制中心可以设置在边缘服务器中,也可以设置在系统中继设备层中的服务器中,具体的设置方式本发明实施例不做具体限定。但由于中继设备层的服务器具有与系统中所有的边缘服务器进行更好的数据传输性能,因此,控制中心较多的是设置在中继设备层的服务器中,接收并处理边缘服务器发送的直播视频播放请求。
202、根据预置的路径配置策略为播放请求实时计算数据下载路径信息。
控制中心在接收到直播视频播放请求后,将根据预置的路径配置策略,配置一条传输速率最优的数据传输路径,该路径由多个CDN系统中的节点服务器所组成。其中,预置的路径配置策略是由管理员根据直播平台以及边缘服务器的具体配置情况设置的配置策略,通过监控CDN系统中各个节点服务器当前的数据传输性能,计算出一条从直播平台中存储有直播视频数据的服务器到边缘服务器的数据传输速率最高的路径,此外,该策略中还会考虑到距离,是否跨区、跨运营商等因素,对路径的规划进行综合配置,得到兼顾传输速率与传输成本的最优化路径。由于在这些参数的采集与计算过程中需要占用较大的处理资源,因此,将路径规划的功能从边缘服务器中分离出来,可以减少边缘服务器的处理压力,将整个系统的路径规划功能集中到控制中心,集中处理直播平台到各个边缘服务器的路径配置计算。
203、将数据下载路径信息发送至边缘服务器。
当控制中心为播放请求计算出最优的数据下载路径后,将得到的数据下载路径信息作为相应边缘服务器所发送的播放请求的响应信息反馈给边缘服务器。
结合上述的实现方式可以看出,本发明实施例所采用的直播视频的上传方法,通过边缘服务器接收客户端观看直播视频的播放请求,并将该请求上报给控制中心,由控制中心根据整个CDN系统网络的当前状态为该播放请求配置一个直播视频的数据下载路径信息,并将该数据下载路径信息反馈给边缘服务器,由边缘服务器根据该数据下载路径信息制定的路径向直播平台获取对应的直播视频的视频数据,并转发至该客户端进行播放。相比现有的播放直播视频的方法,本发明实施例所采用的播放方法是根据整个CDN系统网络的数据传输状态动态计算出的数据传输路径,而非固定在边缘服务器中的固定路径,能够有效的避开网络中拥堵或者故障的问题节点,使得直播视频播放的更加流畅。同时,在需要修改配置路径的策略时,也只需要在控制中心进行策略的调整即可,省去了到各个边缘服务器中修改路径配置文件的步骤,简化了配置流程,提高了路径配置的响应效率。
为了更加详细地说明本发明实施例所提出的直播视频的播放方法,以下将综合上述的两种方法加以说明,如图3所示,该方法所包括的具体步骤为:
301、边缘服务器接收观看直播视频客户端的播放请求。
边缘服务器在CDN系统中为分布式设置,不同地域或不同运营商的用户所发送播放请求会发送到不同的边缘服务器中。而边缘服务器自身也会根据处理能力的大小利用CDN系统中的负载均衡系统将部分用户的请求转给其他的边缘服务器处理。在用户的角度看,就是在直播平台中选择想要观看的频道或者是直播视频。
302、由边缘服务器将播放请求发送至控制中心。
边缘服务器在收到客户端的播放请求后,会将该播放请求发送至控制中心,并且在发送前会将边缘服务器的地址信息添加到播放请求中,以便控制中心能够确认该播放请求是由哪一个边缘服务器所发送的。同时,也便于将该边缘服务器的地址确定为数据下载路径的终点地址。边缘服务器的地址信息可以为该节点的IP地址,将该IP地址与播放请求组成下载路径请求发送给控制中心,由控制中心为该客户端计算直播视频的数据下载路径。
303、控制中心根据接收到的播放请求以及预置的路径配置策略实时计算数据下载路径信息。
控制中心在接收到边缘服务器发送的下载路径请求后,将解析该下载路径请求,得到边缘服务器的地址信息和客户端发送的播放请求,再根据播放请求提取该客户端的用户信息。其中,用户信息的内容包括有用户名、用户的IP地址等基本信息。通过对客户端信息的识别与判断,能够确定该客户端是否有权限观看其请求的直播视频,例如,判断该用户是否在直播平台中已注册,判断该用户的注册账号中的费用是否够支付观看直播视频的费用等。确认该用户具有观看直播视频的权限后,会根据预置的路径配置策略进行路径的规划。其中,具体的策略是由管理员根据实际的需求设置,本发明实施例在此不做具体限制。而该策略的主要目标是要配置一条数据传输速率高,且成本相对低的数据传输路径,例如,根据系统中各个节点服务器的数据传输状态先确定哪些节点是可用的节点,再在这些节点中选择一条节点数量最少且为同运营商的传输路径以降低数据传送的成本。
其中,控制中心在确定系统中各个节点服务器的数据传输状态时所采用的方式可以是通过与CDN系统中的各个节点通过发送保活报文的方式,由控制中心周期性的向节点服务器发送消息,并接受各节点的响应消息,以此来确定各节点服务器的数据传输状态。
进一步的,由于根据预置策略所计算出的数据下载路径是由多个CDN系统中的节点服务器所组成的,因此,该数据下载路径信息可以由节点服务器的IP地址以列表的形式展现,根据路径中经过节点服务器的顺序依次排列出相对应的IP地址,生成一个节点地址列表。其中,该节点地址列表中的首节点地址为直播平台中存储直播视频的资源服务器的地址,终节点地址为发送播放请求的边缘服务器的地址,而中间为多个数据传输速率较高的节点服务器的地址。通过这个节点地址列表,直播视频的数据就可以快速的传递到边缘服务器中。
为了便于将该节点地址列表发送给边缘服务器,可以对该节点地址列表进行压缩,得到压缩后的数据下载路径信息。
304、由边缘服务器接收控制中心返回的数据下载路径信息。
边缘服务器在接收到303中计算得到的数据下载路径信息后,根据该数据下载路径信息的具体格式进行解析,得到其中的节点地址列表。
305、根据数据下载路径信息向直播平台获取播放请求对应的直播视频数据。
边缘服务器根据304中解析得到的节点地址列表,查找在路径中与该边缘服务相邻的上一级节点服务器,并根据该节点服务器的IP地址将播放请求以及数据下载路径信息一同发送至该节点服务器。再有该节点服务器根据解析出的节点地址列表查找上一级节点服务器,以此类推,直至将播放请求发送至节点地址列表中的首节点为止,即发送到直播平台中存储有直播视频数据的资源服务器。由该资源服务器将对应的直播视频数据按照上述播放请求的传输路径反向的发送至边缘服务器。
306、边缘服务器向客户端发送直播视频数据。
以用户的角度看,边缘服务器向用户所在客户端发送直播视频数据就是响应该客户端在301中选择的频道或直播视频,客户端根据接收到的数据播放直播视频。
进一步的,作为对上述方法的实现,本发明实施例提供了一种直播视频的播放装置,该装置设置在CDN网络系统中的资源服务器内,如图4所示,该装置包括:
