相关的视频流数据获取方法，例如，通过在移动终端和拉流业务集群中间增加一个七层负载均衡网关和一个四层网关实现连接迁移等经常会存在如下技术问题：在移动终端和拉流业务集群中间增加两个多层网关，增加了拉流数据包从移动终端到达到拉流业务集群的时间，导致拉流数据包延时；同时，拉流数据包经过两个多层网关时共需要经过两次解包，增加了硬件成本及服务器的负担。
为了解决以上所阐述的问题，本公开的一些实施例提出了视频流数据获取方法及装置，可以在一定程度上避免拉流数据包的延时，同时，拉流数据包无需经过多次解包，减轻了服务器负担。
下面将参考附图并结合实施例来详细说明本公开。
图1是本公开的一些实施例的视频流数据获取方法的一个应用场景的示意图。
在图1的应用场景中，首先，计算设备101可以响应于接收到目标终端102发送的拉流数据包103，确定接收上述拉流数据包103的通信机房的机房标识104与上述拉流数据包103中的连接标识包括的目标机房标识105是否相同，其中，上述拉流数据包103是上述目标终端102在播放视频流时所产生的，上述目标机房标识105是接收上述目标终端102在播放上述视频流时产生的首个拉流数据包的通信机房的机房标识。然后，计算设备101可以响应于确定上述目标机房标识105与接收到上述拉流数据包103的通信机房的机房标识104不同，将上述拉流数据包103转发至上述目标机房标识105对应的目标通信机房106。最后，计算设备101可以通过上述目标通信机房106获取视频流数据107。

应该理解，图1中的计算设备的数目仅仅是示意性的。根据实现需要，可以具有任意数目的计算设备。
继续参考图2，示出了根据本公开的视频流数据获取方法的一些实施例的流程200。该视频流数据获取方法，包括以下步骤：
步骤201，响应于接收到目标终端发送的拉流数据包，确定接收拉流数据包的通信机房的机房标识与拉流数据包中的连接标识包括的目标机房标识是否相同。
在一些实施例中，视频流数据获取方法的执行主体(如图1所示的计算设备101)可以响应于接收到目标终端发送的拉流数据包，确定接收上述拉流数据包的通信机房的机房标识与上述拉流数据包中的连接标识包括的目标机房标识是否相同。其中，上述拉流数据包可以是上述目标终端在播放视频流时所产生的，上述目标机房标识可以是 接收上述目标终端在播放上述视频流时产生的首个拉流数据包的通信机房的机房标识。上述视频流可以是直播视频流，也可以是点播视频流。上述拉流数据包可以是QUIC(Quick UDP Internet Connection，快速UDP(User Datagram Protocol，用户数据报协议)互联网连接)数据包。上述目标终端可以是移动终端，例如，手机、平板电脑等。
接收上述拉流数据包的通信机房可以是上述目标终端发送上述拉流数据包时，所连接的网络所对应的通信机房。上述目标终端在播放上述视频流的过程中，所连接的网络可以是移动网络或无线网络。上述目标终端在播放上述视频流的过程中，所连接的网络也可以在移动网络和无线网络之间切换。
上述目标终端可以在发送上述首个拉流数据包时，将当前所连接的网络对应的通信机房作为目标通信机房。并将该目标通信机房的通信机房标识作为目标通信机房标识写入上述首个拉流数据包的连接标识中。并在播放上述视频流的过程中，将上述目标通信机房标识写入后续产生的拉流数据包的连接标识中。
若上述拉流数据包的通信机房的机房标识与上述拉流数据包中的连接标识包括的目标机房标识相同，则表明接收上述拉流数据包的通信机房与接收上述首个拉流数据包的通信机房是同一通信机房。因此，无需进行连接迁移，可直接通过接收上述拉流数据包的通信机房获取视频流数据。
若上述拉流数据包的通信机房的机房标识与上述拉流数据包中的连接标识包括的目标机房标识不相同，则表明接收上述拉流数据包的通信机房与接收上述首个拉流数据包的通信机房是不同的通信机房，即，上述目标终端在播放上述直播视频流的过程中，所连接的网络在移动网络和无线网络之间发生了切换。因此，为了确保在网络发生切换时，上述目标终端可以继续顺畅的播放上述视频流，需要通过连接回源操作将上述拉流数据包转发至上述目标通信机房。
由此，可以通过上述拉流数据包的中的连接标识包括的目标机房标识确定当前接收拉流数据包的通信机房是否为目标通信机房。从而，实现拉流数据包的快速路由。
作为示例，若上述目标终端发送上述拉流数据包时所连接的网络是长春移动的5G网络，则接收上述拉流数据包的通信机房可以是长春移动机房。
在一些实施例的一些可选的实现方式中，上述目标通信机房可以通过以下步骤确定：
将上述目标终端在播放上述视频流的过程中产生首个拉流数据包时，所连接的网络所对应的通信机房确定为目标通信机房。
由此，可以将产生首个拉流数据包时，上述目标终端所连接的网络所对应的通信机房确定为目标通信机房。进而，在后续网络发生切换时，实现拉流数据包的快速路由。
步骤202，响应于确定目标机房标识与接收到拉流数据包的通信机房的机房标识不同，将拉流数据包转发至目标机房标识对应的目标通信机房。
在一些实施例中，上述执行主体可以响应于确定上述目标机房标识与接收到上述拉流数据包的通信机房的机房标识不同，将上述拉流数据包转发至上述目标机房标识对应的目标通信机房。
步骤203，通过目标通信机房获取视频流数据。
在一些实施例中，上述执行主体可以在将上述拉流数据包转发至上述目标通信机房后，获取上述目标通信机房返回的视频流数据。
在一些实施例的一些可选的实现方式中，上述执行主体还可以执行以下步骤：
第一步，利用目标内部网关协议将上述拉流数据包发送至上述通信机房中的任一协议转换服务器。其中，上述目标内部网关协议可以是OSPF(Open Shortest Path First开放式最短路径优先)。上述协议转换服务器可以是QUIC服务器集群中的任一QUIC服务器。上述QUIC服务器可以将QUIC协议转换为HTTP(Hyper Text Transfer Protocol，超文本传输协议)协议后从内容分发网络边缘节点中获取视频流数据。
由此，可以利用上述目标内部网关协议将上述拉流数据包通过至少一条最短路由路径发送至上述通信机房中的任一协议转换服务器，加快拉流数据包的路由速度。
第二步，利用上述任一协议转换服务器中的单机负载服务为上述拉流数据包分配拉流服务实例。其中，上述单机负载服务可以是操作系统内核级别的负载服务。例如，nftable。
从而，通过操作系统内核级别的负载服务减轻服务器的压力。
第三步，响应于确定上述目标机房标识与上述通信机房的机房标识相同，利用上述拉流服务实例，通过上述通信机房获取视频流数据。其中，上述拉流服务实例可以首先将上述拉流数据包转换为HTTP协议数据包，然后，从上述通信机房中的CDN(Content Delivery Network，内容分发网络)服务器获取视频流数据。
本公开的上述各个实施例具有如下有益效果：通过本公开的一些实施例的视频流数据获取方法，可以在一定程度上避免拉流数据包的延时，同时，拉流数据包无需经过多次解包，减轻了服务器负担。具体来说，造成拉流数据包延时，且服务器负担较重的原因在于：在移动终端和拉流业务集群中间增加一个七层的网关和一个四层的网关。基于此，本公开的一些实施例的视频流数据获取方法，在拉流数据包中的连接标识中增加一个字节用于保存目标机房信息，根据目标机房信息直接对数据包进行转发回源。由此，在移动终端和拉流业务集群中无需存在七层的网关，在一定程度上避免了拉流数据包的延时，缓解了服务器的负担，同时加快了拉流数据包的路由速度。
参考图3，其示出了视频流数据获取方法的另一些实施例的流程300。该视频流数据获取方法的流程300，包括以下步骤：
步骤301，响应于接收到目标终端发送的拉流数据包，确定接收拉流数据包的通信机房的机房标识与拉流数据包中的连接标识包括的目标机房标识是否相同。
在一些实施例中，步骤301的具体实现方式及所带来的技术效果可以参考图2对应的那些实施例中的步骤201，在此不再赘述。
步骤302，利用目标内部网关协议将拉流数据包发送至通信机房中的任一协议转换服务器。
在一些实施例中，视频流数据获取方法的执行主体(如图1所示 的计算设备101)可以利用目标内部网关协议将上述拉流数据包发送至上述通信机房中的任一协议转换服务器。其中，上述目标内部网关协议可以是OSPF。上述协议转换服务器可以是QUIC服务器集群中的任一QUIC服务器。上述QUIC服务器可以将QUIC协议转换为HTTP协议后从内容分发网络边缘节点中获取视频流数据。
由此，可以利用上述目标内部网关协议将上述拉流数据包通过至少一条最短路由路径发送至上述通信机房中的任一协议转换服务器，加快拉流数据包的路由速度。
步骤303，利用任一协议转换服务器中的单机负载服务为拉流数据包分配拉流服务实例。
在一些实施例中，上述执行主体可以利用上述任一协议转换服务器中的单机负载服务为上述拉流数据包分配拉流服务实例。其中，上述单机负载服务可以是操作系统内核级别的负载服务。例如，nftable。由此，可以通过操作系统内核级别的负载服务减轻服务器的压力。
步骤304，响应于确定目标机房标识与通信机房的机房标识不同，利用拉流服务实例，将拉流数据包转发至目标机房标识对应的目标通信机房。
在一些实施例中，上述执行主体可以响应于确定上述目标机房标识与上述通信机房的机房标识不同，利用上述拉流服务实例，将上述拉流数据包转发至上述目标机房标识对应的目标通信机房。
由此，将转发回源功能集成到拉流服务实例中，不再单独存在7层负载均衡网关，减少了数据延迟。同时，减少了由于7层负载均衡网关的单点故障。且由于无需部署7层负载均衡网关也可以降低成本。
步骤305，确定目标通信机房中的目标协议转换服务器中与拉流数据包相匹配的目标拉流服务实例。
在一些实施例中，上述执行主体可以确定上述目标通信机房中的目标协议转换服务器中与上述拉流数据包相匹配的目标拉流服务实例。
上述目标通信机房可以在接收到上述目标终端在播放上述视频流的过程中产生的首个拉流数据包后，将上述目标通信机房中接收上述 首个拉流数据包的协议转换服务器的协议转换服务器标识，和在上述协议转换服务器中为上述首个拉流数据包分配的拉流服务实例的拉流服务实例标识发送给上述目标终端，以供上述目标终端将上述协议转换服务器标识和上述拉流服务实例标识写入后续产生的拉流数据包中。由此，上述执行主体可以根据上述拉流数据包中包括的协议转换服务器标识和拉流服务实例标识确定目标协议转换服务器，以及上述目标协议转换服务器中的目标拉流服务实例。
在一些实施例的一些可选的实现方式中，上述执行主体确定上述目标通信机房中的目标协议转换服务器中与上述拉流数据包相匹配的目标拉流服务实例，可以包括以下步骤：
第一步，从上述目标通信机房中的协议转换服务器集群的缓存服务器中获取映射表。其中，上述映射表中包括映射信息，上述映射信息包括：连接标识，协议转换服务器标识和拉流服务实例标识。上述缓存服务器存储的数据可以是上述协议转换服务器集群共享的数据。
作为示例，上述缓存服务器可以是Redis服务器。
第二步，从上述映射表中选择出包括的连接标识与上述拉流数据包中的连接标识相同的映射信息作为目标映射信息。
第三步，将上述目标映射信息中协议转换服务器标识对应的协议转换服务器确定为目标协议转换服务器。
第四步，将上述目标协议转换服务器中与上述目标映射信息中拉流服务实例标识对应的拉流服务实例，确定为与上述拉流数据包相匹配的目标拉流服务实例。
可选的，上述映射表中的映射信息通过以下步骤确定：
第一步，将上述首个拉流数据包中的连接标识、上述目标协议转换服务器的协议转换服务器标识和上述目标拉流服务实例的拉流服务实例标识确定为映射信息。
第二步，将上述映射信息记录在上述缓存服务器中的映射表中。
可选的，上述目标协议转换服务器和目标拉流服务实例可以通过以下步骤确定：
第一步，响应于确定上述目标通信机房接收到上述首个拉流数据 包，从上述目标通信机房中的协议转换服务器集群中选取一个协议转换服务器作为目标协议转换服务器。其中，上述目标协议转换服务器可以是从上述协议转换服务器集群中随机选取的。
第二步，利用上述目标协议转换服务器中的单机负载服务为上述首个拉流数据包分配拉流服务实例，以及将上述拉流服务实例作为目标拉流服务实例。其中，可以利用单机负载服务为上述首个拉流数据包创建一个拉流服务实例。
作为示例，参考图4，首先，可以响应于确定上述目标通信机房401接收到上述首个拉流数据包402，从上述目标通信机房401中的协议转换服务器集群403中选取一个协议转换服务器作为目标协议转换服务器404。然后，可以利用上述目标协议转换服务器404中的单机负载服务为上述首个拉流数据包402分配拉流服务实例405，以及将上述拉流服务实例作为目标拉流服务实例。
步骤306，利用目标拉流服务实例，从内容分发网络边缘节点获取视频流数据。
在一些实施例中，上述执行主体可以首先利用上述目标拉流服务实例，将上述拉流数据包转换为HTTP协议数据包。然后，从上述通信机房中的内容分发网络边缘节点获取视频流数据。
在一些实施例的一些可选的实现方式中，上述执行主体可以将上述视频流数据发送至上述目标终端。
从图3中可以看出，与图2对应的一些实施例的描述相比，图3对应的一些实施例中的视频流数据获取方法的流程300体现了对拉流数据包进行转发以及获取视频流数据的详细步骤。由此，这些实施例描述的方案可以利用目标内部网关协议和单机负载服加快拉流数据包路由速度，并减轻服务器的压力。
