Description

一种推送视频流的方法、装置、设备和存储介质 技术领域
本申请涉及内容分发网络和数据传输技术，尤其涉及一种推送视频流的方法、装置、设备和存储介质。
背景技术
随着互联网的发展，用户的增长，内容分发网络(CDN)技术有了快速的发展。
内容分发网络(CDN)是一种新型网络内容服务体系，其基本思路是尽可能避开互联网上有可能影响数据传输速度和稳定性的瓶颈和环节，使内容传输的更快、更稳定。通过在网络各处放置节点服务器，构成在现有的互联网基础之上的一层智能虚拟网络，CDN系统能够实时地根据网络流量和各节点的连接、负载状况以及到用户的距离和响应时间等综合信息将用户的请求重新导向离用户最近的服务节点上。其目的是使用户可就近取得所需内容，解决网络拥挤的状况，提高用户访问网站的响应速度。
从2016年进入直播元年后，直播行业也进入快速发展的阶段。直播行业的快速发展同时对网络内容服务体系也提出了更高的要求。由于至今CDN的技术相对稳定和成熟，对于直播行业中用户的多种自建和私有化定制需求的支持程度较低。为了提高支持程度，在CDN的基础上，引进了边缘计算的技术。
在直播行业中，传统的推送视频流的方案是：通过CDN根据域名系统(服务)协议(DNS)进行调度和覆盖。这会导致视频流从边缘 计算到CDN机房的转发无法精确定位，只能通过公网传输。而公网的不稳定性进而影响推流质量和时延，同时，通过公网向CDN进行转推流容易出现路由绕路和路由不通的情况。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
一台服务器，本身具有主机号、IP地址等固有的信息。当这台服务器被设置为内容分发网络(CDN)的节点的时候，会附带有CDN特有的信息，比如，它在哪个层级，地理位置是什么等。
在直播行业中，通常是主播客户端产生视频流，主播客户端推流到CDN，CDN内部进行转推流，观众客户端再从CDN进行拉流。
直播平台为了提高主播推流、用户拉流和转推流的质量，一般会部署自己的服务器和边缘计算方式。那么就可能出现公用的边缘计算、专门的边缘计算(直播平台自己部署的边缘计算)、公用的计算节点和专门的计算节点(直播平台自己部署的边缘计算)。理论上，直播平台会对专门的边缘计算和专门的计算节点之间的交互进行优化。当一个地区对服务器的需求量较大时，会在该地区布置多个服务器。多个服务器通过局域网连接，通常叫做同机房，同机房之间的传输速度比公用的CDN更快，也更加稳定。
但是，公用的边缘计算和公用的计算节点是一个独立的产品，专门的边缘计算和专门的计算节点是一个独立的产品。同时，二者均采用资源透明化调度的方案，即，用户使用边缘计算资源和CDN资源都无法触及底层资源，不知道底层资源用的什么配置，机房在什么地方。这就导致较难同时利用二者的优势，如：公用的边缘计算和公用的计算节点的覆盖面全，而专门的边缘计算和专门的计算节点传输速度快、时延低，信息稳定。
因此，本申请根据提供一种推送视频流的方法，以实现智能识别是否需要进行同机房转推流，从而将公用资源与专门资源进行无缝衔接。
图1为本申请提供的一种推送视频流的系统结构。参考图1，该结构包括调度模块和资源管理模块。
资源管理模块通过自身管理功能，将节点机进行属性标记，即该节点机作为专门的计算节点的节点属性和作为内容分发网络(CDN)的节点的服务器属性。这样可以实现对节点机的横向管理，即不管视频流的来源是公用的边缘计算还是专门的边缘计算，均可以通过资源管理模块进行中转管理，上层业务平台，尤其是直播平台这种业务的平台，可以无缝跨平台实现资源管理。
资源管理模块还可以对专门的计算节点中的节点机按质量和成本进行监控，更新健康度和可用性。根据更新健康度和可用性进行分档，以支持针对用户需求提供和匹配对应档位的资源，并支持优先级。
因此，当CDN的节点机和边缘计算的节点机同机房时，采用本方案的推送视频流的方法，可以使用机房内的局域网进行视频流的传输，获得比通过外网传输更加快速和稳定的传输效果。
图2为本申请实施例提供的一种推送视频流的方法的流程图。本实施例可适用于一台设备在接入了互联网的同时，还接入了局域网的场景。该方法可以由一种推送视频流的装置来执行，该装置可以由软件和/或硬件的方式实现，通常配置于推送视频流的系统中的调度模块中。参考图2，该方法具体包括：
S1、接收第一节点机发出的查询请求，所述第一节点机接收视频流时产生所述查询请求。
节点机一般是一台服务器，本身具有主机号、IP地址等固有信息。当一台节点机被设置为CDN的节点时，会附带CDN特有的信息，如该节点所在的层级、该节点所在的地理位置。当该节点同时又属于一边缘计算节点时，还具有属于边缘计算节点的标识。这里所说的第一节点机与后文提到的第二节点机均为节点机，是为了在说明书中便于指代和区分而且做的名称上的区别。
节点机关联有主播客户端，当主播客户端产生视频流时，与之关联的节点机接收该视频流，将接收主播客户端产生的视频流的节点机称为第一节点机。
节点机与调度模块相关联，当第一节点机接收到视频流，产生查询信息。该查询信息包括第一节点机的各种信息，如：主机号、IP地址、所在的层级、所在的地理位置等。
第一节点机将查询信息发送给调度模块。
S2、根据所述查询请求确定第二节点机，所述第二节点机与所述第一节点机同机房，或者，所述第二节点机符合对所述第一节点机进行域名解析的结果。
查询信息中携带有第一节点机的各种信息，调度模块根据查询信息中携带的各种信息，判断第一节点机是否有同机房的节点机。如果第一节点机存在同机房的节点机，那么从同机房的节点机中选择一台节点机作为第二节点机。如果第一节点机不存在同机房的节点机，那么就根据一般的域名解析规则从互联网中确定一台地理位置相近的节点机作为第二节点机。
在一具体的实现方式中，如图3所示，可以通过如下步骤根据所述查询请求确定第二节点机：
S201、解析所述查询请求。
调度模块对查询请求进行解析，获得解析结果。判断该解析结果中是否具有标识信息。标识信息是标识第一节点机是否属于某一局域网的标志。由于局域网一般是直播平台为了优化对视频流的处理而设置的，因此，一般会有直播平台设定的标识。可以通过标识直接确定过第一节点机是否存在同机房的其他节点机。
具体的，一主播客户端通过一直播平台上传视频流，该视频流具有该直播平台的标识。当第一节点机收到该视频流时，向调度模块发起的查询请求中，会携带这一标识。
S202、当所述查询请求携带有所述第一节点机的标识信息，确定所述第一节点机所在的机房。
调度模块从解析结果中查询到标识信息后，通过资源管理模块确定第一节点机所在的机房。
S203、从所述机房中确定第二节点机。
调度模块通过资源管理模块确定第一节点机所在的机房，同时确定该机房中的其他节点机，从其他节点机中确定一台节点机作为第二节点机。
步骤S201-S203是通过客户端与直播平台的关系来对视频流进行打标识的处理。当调度模块查询到该标识后进行同机房的推流操作，节约了视频流的传输时间，增加了视频流的稳定性。
在一具体的实现方式中，如图4所示，可以通过如下步骤根据所述查询请求确定第二节点机：
S211、解析所述查询请求。
调度模块对查询请求进行解析，获得解析结果。解析结果中包括第一节点机的身份信息。由于局域网一般是直播平台为了优化对视频流的处理而设置的，因此，可以通过身份信息确定过第一节点机是否存某一直播平台可用的同机房的其他节点机。
S212、从所述查询请求中确定所述第一节点机的身份信息,述身份信息表示所述第一节点机的归属。
调度模块从解析结果中查询第一节点机的身份信息，身份信息表示所述第一节点机的归属。第一节点机可能归属于某一直播平台，也可能归属于提供CDN服务的运营商。
S213、当所述身份信息符合预设条件时，确定所述第一节点机所在的机房。
当第一节点机的身份信息属于部署机房的直播平台时，通过资源管理模块确定第一节点机所在的机房。
S214、从所述机房中确定第二节点机。
调度模块通过资源管理模块确定第一节点机所在的机房，同时确定该机房中的其他节点机，从其他节点机中确定一台节点机作为第二节点机。
S215、当所述身份信息不符合预设条件时，则确定所述第一节点机的IP地址。
当第一节点机的身份信息不属于部署机房的直播平台时，则直接在解析结果中确定第一节点机的IP地址。
S216、根据所述IP地址和域名解析规则确定第二节点机。
域名解析(DNS)是一个与数字匹配的名称目录。在这种情况下，数字是IP地址，计算机用它们相互通信。DNS服务器分布在世界各地，存储在域名服务器上，这些域名服务器定期相互通信以提供更新。每个指定的站点可以对应多个IP地址。
步骤S211-S216是通过第一节点机与直播平台的关系来确定是否可以进行同机房转推流。如果可以，则优先选择同机房转推流，节约了视频流的传输时间，增加了视频流的稳定性。如果不可以，则根据域名解析规则进行转推流，兼容传统和同机房两种转推流调度方案。
在上述实施例的基础上，步骤S203与步骤S214提到的从所述机房中确定第二节点机，参考图5，可以通过如下步骤进行：
S221、确定所述机房中的候选节点机的性能，所述候选节点机为所述机房中、除第一节点机以外的其他节点机。
当确定第一节点机所在的机房后，将该机房中除第一节点机以外的其他节点机确定为候选节点机。
一般的，候选节点机的性能至少包括如下的一种：候选节点机的网络质量、候选节点机的网路时延、候选节点机的资源信息。
在此基础上，节点机的属性信息还可以包括状态信息、资源信息、内存使用率以及CPU状态。状态信息包括：硬件故障、软件故障、正 常。资源信息包括：资源冗余、资源不足。可以对节点机的属性进行权重的确定，然后根据每个节点机的具体情况对节点机进行评分处理，或者排序处理。
S222、对所述候选节点机的性能进行统计，以从所述候选节点机中确定第二节点机。
对所述候选节点机的性能进行统计，选择排序最靠前或者得分最高的节点机作为第二节点机。
通过丰富调度模块的控制层级，实现节点和服务器双层多维度调度(节点网络质量、节点网路时延、服务器性能等维度)，保障转推流的最优质量。
S3、向所述第一节点机发送所述第二节点机的地址，以使所述第一节点机向所述第二节点机推送视频流。
调度模块确定所述第二节点机的地址后，将该地址按照预设的格式发送给第一节点机。第一节点机接收该地址，并向该地址推送视频流。
图6为本申请实施例提供的一种同机房推送视频流的示意图。参考图6对同机房推送视频流进行说明。主播在主播客户端产生视频流，主播客户端定义有私有协议，一般是基于RTMP(Real Time Messaging Protocol，实时消息传输协议)去定制的，主要是一些传输上面的优化。主播客户端将视频流通过私有协议推流到第一节点机。第一节点机接收到视频流后，向调度模块发出查询信息。查询信息中携带有第一节点机的各种信息。调度模块关联有资源管理模块，调度模块根据查询信息和资源调度模块中的信息，确定与第一节点机同机房的第二节点机。即第一节点机向调度模块发起查询，以获得与第一节点机同机房的第二节点机的IP地址。调度模块按照预设的格式返回第二节点机的IP地址。第一节点机接收到该IP地址后，向该IP地址指向的第二节点机推送视频流。客户端则从第二节点机进行拉流，以实现整个视 频流的传输。
本实施例通过根据接收视频流的第一节点机的属性信息，确定采用同机房推流还是采用域名解析的方式进行推流。通过这样的方式实现了业务下沉，从而提升推送视频流的稳定性。当视频流是实时产生的直播视频流时，还降低了直播转推流的时延。
