实施例一
图1为本公开实施例一提供的一种视频流获取方法的流程图，本实施例可适用于每个内网中的多个用户端同时获取视频流，以使多个用户同时观看视频的情况，尤其是可以用于在直播场景或者点播场景中，处于同一内网的多个用户端获取视频流的应用场景。例如，可以应用于企业内部培训时，需求每个员工同时观看同一直播视频或者同一点播视频的场景中。该方法可以由视频流获 取装置来执行，该装置可以由软件和/或硬件的方式来实现，集成于用户端中。如图1所示，该方法包括以下步骤：
S110、向媒体服务器发送拉流信息获取请求，以使媒体服务器基于拉流信息获取请求中的目标出口IP地址确定目标内网边缘服务器IP地址，并基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息。
媒体服务器可以是指位于外网的后台服务器。外网是指广域网、公网。用户端是指位于内网中的视频观看端。内网是指局域网，即在一定区域内由多台用户端互联形成的设备组。例如，内网可以由公司内的上千台用户端组成。内网可以为一个或多个。同一内网中的多个用户端可以共同使用一根公共线路与外网的媒体服务器进行通信。同一内网中的多个用户端对应同一个出口IP地址。内网中的每个用户端对应一个内网IP地址，内网IP地址是内网内部分配的，不同内网的IP地址可以重复，不会相互影响。
本公开实施例可以将多个用户端所在区域视为一个工区，并基于网络拓扑结构，可以确定工区与出口IP地址之间的对应关系。例如，一个工区对应一个内网，比如，企业的每个楼层(相当于每个工区)使用不同的内网，也就是说同一内网中的多个用户端分配到同一工区，此时一个工区对应一个出口IP地址。或者，多个工区对应一个内网，比如企业的3楼层和4楼层这两个工区共用同一个内网，也就是说同一内网中的多个用户端分配到多个工区，此时多个工区对应同一个出口IP地址。例如，相关技术中，若工区中的1000个用户端同时观看外网的一场直播或者点播，直播或者点播的默认码率是1Mbps，则该工区对应的出口带宽需要不小于1000Mbps，如果出口带宽过小，就会导致视频发生卡顿，甚至不可观看的情况。
内网边缘服务器可以是指部署在内网中的内容分发网络(Content Delivery Network，CDN)节点，设置为缓存用户端拉取的视频流，以使用户端可以从内网边缘服务器中拉取视频流，无需从外网中拉取，从而节省了视频出口带宽，解决了出口带宽不足的情况。内网边缘服务器可以基于内网拓扑结构和业务需求进行部署。例如，若每个内网中存在一个工区，即一个工区对应一个出口IP地址，则可以针对每个内网(即每个工区)部署相应的一个内网边缘服务器。若每个内网中存在多个工区，即多个工区对应同一个出口IP地址，则可以针对每个内网部署相应的一个内网边缘服务器，也可以针对每个内网中的每个工区部署一个内网边缘服务器，以便节省内网带宽。目标内网边缘服务器可以是指当前待拉流的用户端所对应的内网边缘服务器，以使该用户端可以从该内网边缘服务器中进行拉流。
预设域名生成方式可以是预先设置的，用于将目标内网边缘服务器IP地址添加至域名中的方式，以便通过域名的方式可以将目标内网边缘服务器IP地址传递给用户端，从而告知用户端可以从目标内网边缘服务器IP地址对应的目标内网边缘服务器中进行拉流。
用户端可以向媒体服务器发送拉流信息获取请求，该拉流信息获取请求可以包括该用户端对应的目标出口IP地址和该用户端待拉取的视频流标识，比如视频流名称等。媒体服务器接收到该拉流信息获取请求后，可以基于拉流信息获取请求中的目标出口IP地址确定出相应的目标内网边缘服务器IP地址，并基于预设域名生成方式，生成目标内网边缘服务器IP地址对应的拉流域名，根据该拉流域名获得包含目标内网边缘服务器IP地址信息的目标拉流信息。
S120、获取目标拉流信息，并基于预设域名解析方式，对目标拉流信息进行域名解析，获得目标内网边缘服务器IP地址。
预设域名解析方式可以是指与预设域名生成方式相应的域名泛解析方式，以使用户端可以获得目标拉流信息中的目标内网边缘服务器IP地址。例如，本公开实施例可以在用户端本地进行域名解析操作，以使用户端可以快速获得解析后的目标内网边缘服务器IP地址，提高解析效率；也可以利用位于内网中的域名解析服务器进行域名解析操作，以便内网中的域名解析服务器可以统一处理同一内网中的多个用户端的域名解析操作；还可以利用位于外网中的域名解析服务器进行域名解析操作，以便外网中的域名解析服务器可以统一处理所有内网中的用户端的域名解析操作，节省了设备资源。
示例性地，目标拉流信息的获取操作可以至少通过如下方式进行实现：
作为一种实现方式，S120中的“获取目标拉流信息”，可以包括：接收媒体服务器发送的目标拉流信息。
图2给出了一种视频流获取过程的示例。如图2所示，媒体服务器可以基于用户端发送的拉流信息获取请求中的目标出口IP地址，根据预先配置的出口IP地址与内网边缘服务器IP地址之间的对应关系，直接确定出目标内网边缘服务器IP地址，并基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息，并将目标拉流信息发送至用户端，使得用户端可以通过接收媒体服务器发送的目标拉流信息的方式，获得目标拉流信息。
针对于通过媒体服务器直接获得目标内网边缘服务器IP地址的情况(如图2所示)，可以将同一内网中的多个用户端均对应同一个内网边缘服务器IP地址，从而使得同一内网中的多个用户端均从同一内网边缘服务器中进行拉流。 例如，若一个出口IP地址对应一个工区，即一个内网对应一个工区，则该工区中的用户端可以从同一个内网边缘服务器中进行拉流。若一个出口IP地址对应多个工区，即一个内网对应多个工区，则该内网的所有工区中的用户端也是从同一个内网边缘服务器中进行拉流。
作为另一种实现方式，S120中的“获取目标拉流信息”，可以包括：接收媒体服务器发送的拉流管理信息，其中，拉流管理信息是媒体服务器基于拉流信息获取请求中的目标出口IP地址确定目标内网管理服务器IP地址，并基于预设域名生成方式，根据目标内网管理服务器IP地址进行域名生成确定的；基于预设域名解析方式，对拉流管理信息进行域名解析，获得目标内网管理服务器IP地址；基于目标内网管理服务器IP地址，向目标内网管理服务器发送拉流地址获取请求，以使目标内网管理服务器基于拉流地址获取请求中的目标内网IP地址确定目标内网边缘服务器IP地址，并基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息；接收目标内网管理服务器发送的目标拉流信息。
内网管理服务器可以是预先部署在内网中的，设置为管理该内网中的内网边缘服务器与该内网中的用户端之间的对应关系的设备。在一个出口IP地址对应多个工区时，可以针对每个工区设置一个内网边缘服务器，以便在同一内网中，不同工区中的用户端可以从不同内网边缘服务器中进行拉流，避免了位于该内网的所有工区中的用户端均从同一个内网边缘服务器中进行拉流的情况，节省了内网带宽。本实施例可以在同一内网中部署一个内网管理服务器以及与内网所包含的工区数量相同的内网边缘服务器，从而同一内网中的不同工区可以对应不同的内网边缘服务器。在同一内网中，不同用户端的内网IP地址是不同的，从而可以基于用户端的内网IP地址确定出该用户端所在工区，并基于工区与内网边缘服务器IP地址之间的对应关系，确定出该用户端对应的目标内网边缘服务器IP地址；或者可以基于用户端的内网IP地址与内网边缘服务器IP地址之间的多对一的对应关系，直接确定出该用户端对应的目标内网边缘服务器IP地址。
图3给出了另一种视频流获取过程的示例。如图3所示，媒体服务器可以基于用户端发送的拉流信息获取请求中的目标出口IP地址，根据预先配置的出口IP地址与内网管理服务器IP地址之间的对应关系，确定出目标内网管理服务器IP地址，并基于预设域名生成方式，根据目标内网管理服务器IP地址进行域名生成，并根据生成的域名确定拉流管理信息，并将拉流管理信息发送至用户端。用户端可以基于预设域名解析方式，对接收到的拉流管理信息进行域名解析，获得目标内网管理服务器IP地址，并基于目标内网管理服务器IP地址，向目标内网管理服务器发送拉流地址获取请求，该拉流地址获取请求可以包括该 用户端对应的目标内网IP地址和该用户端待拉取的视频流标识，比如视频流名称等。目标内网管理服务器可以基于接收到的拉流地址获取请求中的目标内网IP地址，根据预先配置的内网IP地址与内网边缘服务器IP地址之间的对应关系，确定出目标内网边缘服务器IP地址，并基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息，并将目标拉流信息发送至用户端，使得用户端可以通过接收目标内网管理服务器发送的目标拉流信息的方式，获得目标拉流信息。
针对于通过利用内网管理服务器间接获得目标内网边缘服务器IP地址的情况(如图3所示)，同一内网中的不同工区中的用户端可以对应不同的内网边缘服务器IP地址，从而使得同一内网中的不同工区中的用户端可以从不同的内网边缘服务器中进行拉流，避免了位于该内网的所有工区中的用户端均从同一个内网边缘服务器中进行拉流的情况，即解决了一个出口IP地址对应多个工区的情况，从而节省了内网带宽。
示例性地，S120中的“基于预设域名解析方式，对目标拉流信息进行域名解析，获得目标内网边缘服务器IP地址”，可以包括：将目标拉流信息发送至域名解析服务器，以使域名解析服务器基于预设域名解析方式，对目标拉流信息进行域名解析，获得目标内网边缘服务器IP地址，其中，域名解析服务器为处于内网的域名解析服务器或者处于外网的域名解析服务器；接收域名解析服务器返回的目标内网边缘服务器IP地址。
用户端可以通过将目标拉流信息发送至位于内网的域名解析服务器，利用位于内网的域名解析服务器可以统一处理同一内网中的多个用户端的域名解析操作。用户端还可以将目标拉流信息发送至位于外网的域名解析服务器，利用位于外网的域名解析服务器可以统一处理所有内网中的用户端的域名解析操作，从而节省了设备资源。
示例性地，基于预设域名解析方式，对目标拉流信息进行域名解析，获得目标内网边缘服务器IP地址，可以包括：提取出目标拉流信息中的具有预设域名格式的目标内网边缘服务器地址信息；将目标内网边缘服务器地址信息解析为IP地址格式，获得目标内网边缘服务器IP地址。
预设域名格式可以是利用预设域名生成方式所生成的域名格式。例如，目标内网边缘服务器IP地址为：10.95.3.11，具有预设域名格式的目标内网边缘服务器地址信息可以为：10-95-3-11。
用户端本地或者位于内网或者外网的域名解析服务器可以提取出所接收到的目标拉流信息中的目标内网边缘服务器地址信息。例如，目标拉流信息中的拉流地址为：https://10-95-3-11.xx.com/yy.m3u8？domain＝aaa.bbb.cn，则提取出的 目标内网边缘服务器地址信息为：10-95-3-11，此时可以将目标内网边缘服务器地址信息解析为IP地址格式，获得目标内网边缘服务器IP地址，比如，10.95.3.11，从而利用域名解析的方式可以实现访问指定的内网边缘服务器的情况。
示例性地，针对于通过利用内网管理服务器间接获得目标内网边缘服务器IP地址的情况(如图3所示)，“基于预设域名解析方式，对拉流管理信息进行域名解析，获得目标内网管理服务器IP地址”，可以包括：提取出拉流管理信息中的具有预设域名格式的目标内网管理服务器地址信息；将目标内管理服务器地址信息解析为IP地址格式，获得目标内网管理服务器IP地址。
可以基于相同域名解析方式，对拉流管理信息进行解析，获得目标内网管理服务器IP地址。例如，拉流管理信息中的目标内网管理服务器地址为：https://10-225-70-182.xx.com:9755/live/stream_config，则提取出的目标内网管理服务器地址信息为：10-225-70-182，此时可以将目标内网管理服务器地址信息解析为IP地址格式，获得目标内网管理服务器IP地址，比如，10.225.70.182，从而利用域名解析的方式可以实现访问指定的内网管理服务器的情况。
S130、基于目标内网边缘服务器IP地址，向目标内网边缘服务器发送目标拉流请求，获取目标内网边缘服务器基于目标拉流请求返回的目标视频流。
用户端可以基于目标内网边缘服务器IP地址，从位于内网的目标内网边缘服务器中进行拉流，该目标内网边缘服务器中可以预先缓存待拉取的视频流；或者，针对接收到的首个用于拉取目标视频流的拉流请求，可以基于拉流请求中的外网拉流地址(比如aaa.bbb.cn)，从外网边缘服务器(比如外网CDN节点)中进行拉流，并将拉取的目标视频流进行缓存，以便针对后续拉取请求可以直接返回所缓存的目标视频流，此时可以将N路视频流需要使用的出口带宽变成只需要一路视频流使用的出口带宽，大大节省了视频出口带宽，避免了因出口带宽不足而导致的视频播放流畅度差的情况，提高了视频流获取效率，同时也提高了视频播放流畅度，大大提升了用户观看体验。
本公开实施例的技术方案，用户端向媒体服务器发送拉流信息获取请求。媒体服务器基于拉流信息获取请求中的目标出口IP地址确定出目标内网边缘服务器IP地址，并基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息。用户端获取目标拉流信息，并基于预设域名解析方式，对目标拉流信息进行域名解析，获得目标内网边缘服务器IP地址，从而可以基于目标内网边缘服务器IP地址，向位于内网中的目标内网边缘服务器发送目标拉流请求，获取目标内网边缘服务器基于目标拉流请求返回的目标视频流。通过在内网中部署内网边缘服务器，并通过域名解析的方式，用户端可以直接从指定的目标内网边缘服务器中拉取视频流，无需从 外网拉取视频流，从而大大节省了出口带宽，并且提高了视频流获取效率，进而保证了视频播放流畅度，提升了用户观看体验。

图4为本公开实施例二提供的一种视频流获取方法的流程图，本实施例可适用于每个内网中的多个用户端同时获取视频流，以使多个用户同时观看视频的情况，尤其是可以用于在直播场景或者点播场景中，处于同一内网的多个用户端获取视频流的应用场景。该方法可以由视频流获取装置来执行，该装置可以由软件和/或硬件的方式来实现，集成于媒体服务器中。如图4所示，该方法包括以下步骤：
S410、接收用户端发送的拉流信息获取请求。
S420、基于拉流信息获取请求中的目标出口IP地址确定目标内网边缘服务器IP地址。
S430、基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息，以使用户端获取目标拉流信息，基于预设域名解析方式，对目标拉流信息进行域名解析，获得目标内网边缘服务器IP地址，并基于目标内网边缘服务器IP地址，向目标内网边缘服务器发送目标拉流请求，获取目标内网边缘服务器基于目标拉流请求返回的视频流。
示例性地，S420可以包括：基于预先配置的出口IP地址与内网边缘服务器IP地址之间的对应关系和拉流信息获取请求中的目标出口IP地址，确定目标内网边缘服务器IP地址；相应地，在S430之后还包括：将目标拉流信息发送至用户端。
针对于通过媒体服务器直接获得目标内网边缘服务器IP地址的情况(如上述实施例中的图2所示)，可以基于业务需求预先在媒体服务器中配置出每个内网对应的出口IP地址与每个内网对应的内网边缘服务器IP地址之间的对应关系，从而在实际使用中，媒体服务器基于该对应关系和拉流信息获取请求中的目标出口IP地址，可以直接确定出该目标出口IP地址对应的目标内网边缘服务器IP地址，并将基于该目标内网边缘服务器IP地址确定的目标拉流信息发送至用户端，从而使得用户端可以获得媒体服务器发送的目标拉流信息。
示例性地，S420和S430可以包括：基于拉流信息获取请求中的目标出口IP地址确定目标内网管理服务器IP地址，并基于预设域名生成方式，根据目标内网管理服务器IP地址进行域名生成，并根据生成的域名确定拉流管理信息；将拉流管理信息发送至用户端，以使用户端基于预设域名解析方式，对拉流管 理信息进行域名解析，获得目标内网管理服务器IP地址，并基于目标内网管理服务器IP地址，向目标内网管理服务器发送拉流地址获取请求，以使目标内网管理服务器基于拉流地址获取请求中的目标内网IP地址确定目标内网边缘服务器IP地址，并基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息并进行返回。
内网管理服务器可以参见上述实施例的相关描述，此处不再赘述。
示例性地，目标内网管理服务器基于拉流地址获取请求中的目标内网IP地址确定目标内网边缘服务器IP地址，可以包括：目标内网管理服务器基于预先配置的内网IP地址与内网边缘服务器IP地址之间的对应关系和拉流地址获取请求中的目标内网IP地址，确定目标内网边缘服务器IP地址。
针对于通过利用内网管理服务器间接获得目标内网边缘服务器IP地址的情况(如上述实施例中的图3所示)，可以基于业务需求预先在媒体服务器中配置出每个内网对应的出口IP地址与每个内网对应的内网管理服务器IP地址之间的对应关系，以及基于内网的网络拓扑结构，预先在每个内网管理服务器中配置出每个工区中的每个用户端对应的内网IP地址与该工区对应的内网边缘服务器IP地址之间的对应关系。在实际使用中，媒体服务器可以基于拉流信息获取请求中的目标出口IP地址和预先配置的出口IP地址与内网管理服务器IP地址之间的对应关系，确定出该目标出口IP地址对应的目标内网管理服务器IP地址，并将基于该目标内网管理服务器IP地址确定的拉流管理信息发送至用户端。用户端基于预设域名解析方式，对拉流管理信息进行域名解析，获得目标内网管理服务器IP地址，并基于目标内网管理服务器IP地址，向位于内网的目标内网管理服务器发送拉流地址获取请求。目标内网管理服务器可以基于拉流地址获取请求中的目标内网IP地址和先预配置的内网IP地址与内网边缘服务器IP地址之间的对应关系，确定出目标内网IP地址对应的目标内网边缘服务器IP地址，并基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息并进行返回，从而使得用户端可以获得目标内网管理服务器发送的目标拉流信息。
用户端在接收到媒体服务器发送的目标拉流信息，或者目标内网管理服务器发送的目标拉流信息后，可以基于预设域名解析方式，对目标拉流信息进行域名解析，获得目标内网边缘服务器IP地址，从而利用域名解析的方式可以实现访问指定的内网边缘服务器的情况。其中，域名解决的过程可以参见上述实施例的相关描述，此处不再赘述。用户端可以基于目标内网边缘服务器IP地址，从位于内网的目标内网边缘服务器中进行拉流，无需从外网拉取视频流，从而大大节省了视频出口带宽，避免了因出口带宽不足而导致的视频播放流畅度差 的情况，提高了视频流获取效率，同时也提高了视频播放流畅度，大大提升了用户观看体验。
示例性地，S430中的“基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息”，可以包括：基于预设域名格式，将目标内网边缘服务器IP地址进行格式变换，并将变换后的目标内网边缘服务器地址信息添加至拉流地址中，确定目标拉流信息。
预设域名格式可以是预先设置的，域名所允许的字符格式。例如，目标内网边缘服务器IP地址为：10.95.3.11，利用预设域名格式变换后获得的目标内网边缘服务器地址信息为：10-95-3-11，并可以将该目标内网边缘服务器地址信息拼接到拉流地址中，比如添加到待拉取的目标视频流标识的前面。而且，还可以将实际的外网拉流地址拼接到目标拉流信息中，以使针对首个拉流请求可以从外网拉流地址拉取目标视频流。例如，目标拉流信息对应的拉流地址为：https://10-95-3-11.xx.com/yy.m3u8？domain＝aaa.bbb.cn，其中，xx.com为待拉取的目标视频流标识，aaa.bbb.cn为外网拉流地址。
示例性地，针对于通过利用内网管理服务器间接获得目标内网边缘服务器IP地址的情况(如上述实施例中的图3所示)，“基于预设域名生成方式，根据目标内网管理服务器IP地址进行域名生成，确定拉流管理信息”，可以包括：基于预设域名格式，将目标内网管理服务器IP地址进行格式变换，获得目标内网管理服务器地址信息，并基于目标内网管理服务器地址信息确定拉流管理信息。拉流管理信息除了包括目标内网管理服务器地址之外，还可以包括外网拉流地址，以便在内网边缘服务器的缓存中不存在目标视频流时，可以针对首个拉流请求从外网拉流地址拉取目标视频流并进行缓存。
媒体服务器可以基于与上述目标拉流信息类似的确定方式，确定出拉流管理信息。例如，目标内网管理服务器IP地址为：10.225.70.182，利用预设域名格式变换后获得的目标内网管理服务器地址信息为：10-225-70-182，基于该目标内网管理服务器地址信息生成的拉流管理信息中的目标内网管理服务器地址为：https://10-225-70-182.xx.com:9755/live/stream_config。若用户端需要获取外网拉流地址，则可以将确定的外网拉流地址，比如：https://aaa.bbb.cn/yy.m3u8？domain＝aaa.bbb.cn也添加至拉流管理信息发送至用户端。
本实施例的技术方案，用户端向媒体服务器发送拉流信息获取请求。媒体服务器基于拉流信息获取请求中的目标出口IP地址确定出目标内网边缘服务器IP地址，并基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息。用户端获取目标拉流信息，并基 于预设域名解析方式，对目标拉流信息进行域名解析，获得目标内网边缘服务器IP地址，从而可以基于目标内网边缘服务器IP地址，向位于内网中的目标内网边缘服务器发送目标拉流请求，获取目标内网边缘服务器基于目标拉流请求返回的目标视频流。通过在内网中部署内网边缘服务器，并通过域名解析的方式，用户端可以直接从指定的目标内网边缘服务器中拉取视频流，无需从外网拉取视频流，从而大大节省了出口带宽，并且提高了视频流获取效率，进而保证了视频播放流畅度，提升了用户观看体验。
实施例三
图5为本公开实施例三提供的一种视频流获取方法的流程图，本实施例可适用于每个内网中的多个用户端同时获取视频流，以使多个用户同时观看视频的情况，尤其是可以用于在直播场景或者点播场景中，处于同一内网的多个用户端获取视频流的应用场景。该方法可以由视频流获取装置来执行，该装置可以由软件和/或硬件的方式来实现，集成于内网边缘服务器中。如图5所示，该方法包括以下步骤：
S510、接收用户端基于内网边缘服务器IP地址发送的目标拉流请求，其中，内网边缘服务器IP地址是用户端基于预设域名解析方式，对利用媒体服务器获取到的目标拉流信息进行域名解析获得的。
用户端可以基于待拉取的目标视频流对应的目标视频流标识生成目标拉流请求，或者基于待拉取的目标视频流对应的目标视频流标识和实际的外网拉流地址生成目标拉流请求，并基于通过媒体服务器直接获得的内网边缘服务器IP地址或者通过内网管理服务器间接获得的内网边缘服务器IP地址，向所指定的内网边缘服务器发送目标拉流请求，从而使得内网边缘服务器可以接收到用户端发送的目标拉流请求。
S520、确定目标拉取请求对应的目标视频流，并将目标视频流进行返回，以使用户端获取目标视频流。
内网边缘服务器可以基于用户端发送的目标拉取请求中的目标视频流标识确定出缓存的目标视频流，并将缓存的目标视频流发送至用户端，从而用户端可以直接从位于内网的边缘服务器中进行拉流，无需从外网拉取视频流，从而大大节省了视频出口带宽，避免了因出口带宽不足而导致的视频播放流畅度差的情况，提高了视频流获取效率，同时也提高了视频播放流畅度，大大提升了用户观看体验。
示例性地，S520可以包括：基于目标拉取请求中的目标视频流标识，从预 先缓存的缓存视频流中确定目标视频流。
在点播场景中，可以将每个点播视频预先缓存至每个内网边缘服务器中，从而内网边缘服务器在接收到目标拉取请求时，可以基于待拉取的目目标视频流标识，从缓存的多个视频流中确定出目标视频流，从而同一内网的多个用户端在需要同时观看同一点播视频时，可以直接获得内网边缘服务器缓存的该点播视频，无需从外网拉取视频流，大大节省了出口带宽，并且提高了视频流获取效率，进而保证了视频播放流畅度，提升了用户观看体验。
示例性地，S520可以包括：基于目标拉取请求中的目标视频流标识，检测当前缓存的缓存视频流中是否存在目标视频流；若当前缓存的缓存视频流中存在目标视频流，则将该缓存视频流确定为目标视频流；若当前缓存的缓存视频流中不存在目标视频流，则基于目标拉取请求中的外网拉流地址，向外网边缘服务器拉取目标视频流，并将拉取的目标视频流进行缓存。
在直播场景中，由于直播视频是实时产生的，无法预先缓存直播视频，从而内网边缘服务器在接收到首个用于拉取目标视频流的目标拉流请求时，可以基于拉流请求中的外网拉流地址，从外网边缘服务器(比如外网CDN节点)中进行拉流，并将拉取的目标视频流进行缓存，以便针对后续接收到目标拉取请求时，可以直接返回当前缓存的目标视频流，无需再从外网拉取，从而可以将N路视频流需要使用的出口带宽变成只需要一路视频流使用的出口带宽，大大节省了视频出口带宽，避免了因出口带宽不足而导致的视频播放流畅度差的情况，提高了视频流获取效率，同时也提高了视频播放流畅度，大大提升了用户观看体验。
本公开实施例的技术方案，用户端向媒体服务器发送拉流信息获取请求。媒体服务器基于拉流信息获取请求中的目标出口IP地址确定出目标内网边缘服务器IP地址，并基于预设域名生成方式，根据目标内网边缘服务器IP地址进行域名生成，并根据生成的域名确定目标拉流信息。用户端获取目标拉流信息，并基于预设域名解析方式，对目标拉流信息进行域名解析，获得目标内网边缘服务器IP地址，从而可以基于目标内网边缘服务器IP地址，向位于内网中的目标内网边缘服务器发送目标拉流请求，获取目标内网边缘服务器基于目标拉流请求返回的目标视频流。通过在内网中部署内网边缘服务器，并通过域名解析的方式，用户端可以直接从指定的目标内网边缘服务器中拉取视频流，无需从外网拉取视频流，从而大大节省了出口带宽，并且提高了视频流获取效率，进而保证了视频播放流畅度，提升了用户观看体验。
