Description
本申请基于巴黎公约申明享有2017年12月13日递交的申请号为201711323476.9、名称为“推流服务器的调度装置、方法及计算机可读存储介质”的中国专利申请的优先权,该中国专利申请的整体内容以参考的方式结合在本申请中。
本申请涉及直播技术领域,尤其涉及一种推流服务器的调度装置、方法及计算机可读存储介质。
在进行网络直播时,推流客户端(主播用户)以流媒体的形式将直播视频推送到源服务器,直播视频的典型特征是把连续的视频信息压缩后放到流媒体服务器上,用户边下载边观看,而不必等待整个文件下载完毕。直播客户端(直播观众)发出观看请求,由直播平台中的源服务器将直播视频文件流拉到观看方的客户端。
核心节点的源服务器在接收到推流客户端的推流请求后,直接将请求分配给服务器群组中负载较小的服务器处理,这种方式通过采集各服务器的状态信息等数据计算负载情况,但是这种分配方式存在下述缺陷:一台服务器同时负担较多的推流任务,各个推流任务的参数、状态等不相同,导致数据采集延时或者不准确;由于该缺陷的存在,导致推流服务器的调度精确度低,进而导致视频流的上传速率不稳定。

应当理解,此处所描述的具体实施例仅仅用以解释本申请,并不用于限定本申请。
本申请提供一种推流服务器的调度装置。参照图1所示,为本申请推流服务器的调度装置较佳实施例的示意图。
在本实施例中,该推流服务器的调度装置至少包括存储器11、处理器12,通信总线13,以及网络接口14。
其中,存储器11至少包括一种类型的可读存储介质,所述可读存储介质包括闪存、硬盘、多媒体卡、卡型存储器(例如,SD或DX存储器等)、磁性存储器、磁盘、光盘等。存储器11在一些实施例中可以是推流服务器的调度装置的内部存储单元,例如该推流服务器的调度装置的硬盘。存储器11在另一些实施例中也可以是推流服务器的调度装置的外部存储设备,例如推流服务器的调度装置上配备的插接式硬盘,智能存储卡(Smart Media Card,SMC),安全数字(Secure Digital,SD)卡,闪存卡(Flash Card)等。进一步地,存储器11还可以既包括推流服务器的调度装置的内部存储单元也包括外部存储设备。存储器11不仅可以用于存储安装于推流服务器的调度装置的应用软件及各类数据,例如推流服务器的调度程序的代码等,还可以用于暂时地存储已经输出或者将要输出的数据。
处理器12在一些实施例中可以是一中央处理器(Central Processing Unit,CPU)、控制器、微控制器、微处理器或其他数据处理芯片,用于运行存储器11中存储的程序代码或处理数据,例如执行推流服务器的调度程序等。
通信总线13用于实现这些组件之间的连接通信。
网络接口14可选的可以包括标准的有线接口、无线接口(如WI-FI接口),通常用于在该装置与其他电子设备之间建立通信连接。
图1仅示出了具有组件11-14以及推流服务器的调度程序的推流服务器的调度装置,但是应理解的是,并不要求实施所有示出的组件,可以替代的实施更多或者更少的组件。
可选地,该装置还可以包括用户接口,用户接口可以包括显示器(Display)、输入单元比如键盘(Keyboard),可选的用户接口还可以包括标准的有线接口、无线接口。可选地,在一些实施例中,显示器可以是LED显示器、液晶显示器、触控式液晶显示器以及OLED(Organic Light-Emitting Diode,有机发光二极管)触摸器等。其中,显示器也可以适当的称为显示屏或显示单元,用于显示在推流服务器的调度装置中处理的信息以及用于显示可视化的用户界面。
在图1所示的装置实施例中,存储器11中存储有推流服务器的调度程序;处理器12执行存储器11中存储的推流服务器的调度程序时实现如下步骤:
当接收到推流客户端发送的推流请求时,根据所述推流请求确定所述推流客户端所在的地理区域。
根据预先设置的服务器的层级分布,获取服务器群组中与所述地理区域对应的第一级节点服务器的IP地址,其中,所述服务器群组中的服务器的层级分布与其所在的地理区域的层级分布一致,所述第一级节点服务器为边缘节点服务器且所述地理区域的层级呈树形分布。
预先设地理区域的层级划分,地理区域至少分为两个层级,也可以根据需要设置为更多的层级,以下以三个层级为例进行说明。例如,将地理区域设置分为如下三个层级:第三层级为最高层级,该层级的地理区域包括全国区域范围,第三层级地理区域包括多个第二层级地理区域,如华北区域、东南区域、华南区域、西南区域等,每一个第二层级地理区域又可以划分为多个第一层级地理区域,以华南区域为例,该区域又可以划分为广东区域、广西区域、海南区域等,需要说明的是,上述区域的划分只是举例说明,实际应用时可以根据需要设置区域的划分规则,不一定按照行政区域划分。下一层级地理区域覆盖范围的总和等于上一层级区域的覆盖范围。
按照上述地理区域的层级分布设置服务器群组中服务器的层级分布。在第一层级地理区域部署第一级节点服务器,每一个第一层级地理区域设置至少一台第一级节点服务器,以下内容中以一个第一层级地理区域设置一台第一级节点服务器为例,在广东区域、广西区域、海南区域等分别设置一台第一级节点服务器,在华南区域设置一台第二级节点服务器,则该第二级节点服务器为以上几台第一级节点服务器的上级节点服务器,以此类推,完成各个地理区域的服务器的部署。上述分布在各个区域的服务器构成服务器群组,该服务器群组的层级分布也呈树形,参照图2所示,为服务器群组中的服务器层级分布示意图。此外,可以将服务器群组中的任意一台服务器作为本实施例中的推流服务器的调度装置,可选地,将最高层级的服务器作为本实施例中的推流服务器的调度装置。
为服务器群组中各台服务器分配有IP地址,并且各台服务器的IP地址及其所在地理区域等数据均存储在调度服务器中。
将所述第一级节点服务器作为所述推流客户端的推流服务器。
用户登录推流客户端后,与上述调度装置建立连接,在其发送推流请求,调度装置根据该推流请求,从服务器群组中选择合适的服务器作为其推流服务器。具体地,调度装置根据推流请求确定推流客户端所在的地理区域,按照上述服务器的层级分布,将与该地理区域对应的第一节点服务器作为该推流客户端的推流服务器。关于推流客户端所在的地理区域的确定,参照以下方式:当调度装置接收到推流客户端发送的推流请求时,从推流请求中获取推流客户端的IP地址,根据IP地址确定推流客户端所在的地理区域。推流客户端的推流请求中携带有客户端的IP地址,调度装置根据IP地址确定其所在区域,例如,推流客户端的IP地址位于广东区域,则将广东区域中的第一级节点服务器作为该推流客户端的推流服务器。
将获取的IP地址发送至所述推流客户端,以供所述推流客户端根据所述IP地址将直播的流媒体文件推流至所述IP地址对应的第一级节点服务器。
将该第一级节点服务器的IP地址发送给推流客户端,推流客户端根据接收到的IP地址与上述第一级节点服务器建立连接,将直播的流媒体文件推流到该第一级节点服务器。观众观看该直播时,观众客户端直接从该服务器拉流。
本实施例提出的推流服务器的调度装置,预先配置服务器群组中服务器的层级分布,该服务器群组中的服务器的层级分布与其所在的地理区域的层级分布一致,当接收到推流客户端的推流请求时,确定该推流客户端所在的地理区域,按照上述层级分布,获取服务器群组中与该地理区域对应的第一级节点服务器的IP地址,将该第一级节点服务器作为上述推流客户端的推流服务器,将上述IP地址发送给该推流客户端,该推流客户端将直播的流媒体文件推流至上述第一级节点服务器,上述推流服务器的调度方案按照地理区域的分布合理设置各级节点服务器的分布,能够根据该分布实现对推流服务器的快速调度,该方案就近将推流任务分配到各个地理区域的边缘节点服务器中,提高了推流服务器的调度精确度,进而提高了流媒体文件的上传速率的稳定性。
基于第一实施例提出本申请推流服务器的调度装置的第二实施例。在本 实施例中,推流服务器的调度程序还可被所述处理器执行,以实现如下步骤:
在所述流媒体文件的直播过程中,对所述流媒体文件的观众数量以及观众所在的地理区域进行监测;
当检测到有预设数量的观众所在的地理区域不属于该流媒体文件的推流服务器所在的地理区域时,将所述流媒体文件迁移至该推流服务器的上一级节点服务器,并由该上一级节点服务器接收观众客户端发送的拉流请求。
本实施例中,观众客户端直接从推流服务器拉流,对于一个直播的流媒体文件来说,其观众可能分布在全国各地,当一个直播的观众大部分都不是分布在该直播的推流服务器所在的地理区域时,为了提高观众的下载流媒体文件的效率,将流媒体文件迁移至当前的徒留服务器的上一级节点服务器,迁移之后,有两个层级节点的服务器同时进行推流。迁移之前的观众仍然继续从原来的推理服务器上拉流,不影响观看直播,迁移后,由上述上一级节点服务器接收观众客户端发送的拉流请求。
基于第一实施例或者第二实施例提出本申请推流服务器的调度装置的第三实施例。在本实施例中,推流服务器的调度程序还可被所述处理器执行,以实现如下步骤:
对所述服务器群组中的各台服务器的负载进行实时监测;
以及,在所述根据预先设置的服务器的层级分布,获取服务器群组中与所述地理区域对应的第一级节点服务器的IP地址的步骤之后,还实现如下步骤:
获取所述第一级节点服务器的运行参数,根据所述运行参数判断所述第一级节点服务器的负载是否大于预设阈值;
若否,则执行将所述第一级节点服务器作为所述推流客户端的推流服务器的步骤;
若是,则查找与确定的第一级节点服务器位于同一层级、且靠近该第一级节点服务器的其他第一级节点服务器中负载小于所述预设阈值的第一级节点服务器;获取查找到的第一级节点服务器作为所述推流客户端的推流服务器,并将该第一级节点服务器的IP地址并发送至所述推流客户端。
在该实施例中,结合服务器的层级分布和各台服务器的负载来分配推流 服务器。对服务器群组中的各台服务器的负载进行实时监测。在根据预先设置的服务器的层级分布,获取服务器群组中与地理区域对应的第一级节点服务器的IP地址之后,获取该服务器的运行参数,判断其负载是否大于预设阈值,如果负载小于或等于预设阈值,则将该第一级节点服务器分配给上述推流客户端作为推流服务器。否则,从与其位于同一层级、且靠近该第一级节点服务器的其他第一级节点服务器中负载小于预设阈值的第一级节点服务器分配给上述推流客户端作为推流服务器。进一步地,若与确定的第一级节点服务器位于同一层级的其他第一级节点服务器的负载均大于预设阈值,则获取确定的第一级节点服务器的上一级节点服务器作为推流客户端的推流服务器,并获取其IP地址发送至推流客户端。该方案在考虑服务器的层级分布的基础上,进一步根据服务器的负载情况,为推流客户端分配合理的服务器进行推流,进一步提高了流媒体文件的上传速率的稳定性。
可选地,在其他的实施例中,推流服务器的调度程序还可以被分割为一个或者多个模块,一个或者多个模块被存储于存储器11中,并由一个或多个处理器(本实施例为处理器12)所执行以完成本申请,本申请所称的模块是指能够完成特定功能的一系列计算机程序指令段,用于描述推流服务器的调度程序在推流服务器的调度装置中的执行过程。
例如,参照图3所示,为本申请推流服务器的调度装置一实施例中的推流服务器的调度程序的程序模块示意图,该实施例中,推流服务器的调度程序可以被分割为区域确定模块10、地址获取模块20、服务器分配模块30和信息发送模块40,示例性地:
区域确定模块10用于:当接收到推流客户端发送的推流请求时,根据所述推流请求确定所述推流客户端所在的地理区域;
地址获取模块20用于:根据预先设置的服务器的层级分布,获取服务器群组中与所述地理区域对应的第一级节点服务器的IP地址,其中,所述服务器群组中的服务器的层级分布与其所在的地理区域的层级分布一致,所述第一级节点服务器为边缘节点服务器且所述地理区域的层级呈树形分布;
服务器分配模块30用于:将所述第一级节点服务器作为所述推流客户端的推流服务器;
信息发送模块40用于:将获取的IP地址发送至所述推流客户端,以供所述推流客户端根据所述IP地址将直播的流媒体文件推流至所述IP地址对应的第一级节点服务器。
上述区域确定模块10、地址获取模块20、服务器分配模块30和信息发送模块40等程序模块被执行时所实现的功能或操作步骤与上述实施例大体相同,在此不再赘述。
此外,本申请还提供一种推流服务器的调度方法。参照图4所示,为本申请推流服务器的调度方法第一实施例的流程图。该方法可以由一个装置执行,该装置可以由软件和/或硬件实现。
在本实施例中,推流服务器的调度方法包括:
步骤S10,当接收到推流客户端发送的推流请求时,根据所述推流请求确定所述推流客户端所在的地理区域。

以下内容中,以推流服务器的调度装置作为执行主体对本实施例的方法进行说明,该调度装置可以是下述服务器群组中的服务器中的任意一台。预先设地理区域的层级划分,地理区域至少分为两个层级,也可以根据需要设置为更多的层级,以下以三个层级为例进行说明。例如,将地理区域设置分为如下三个层级:第三层级为最高层级,该层级的地理区域包括全国区域范围,第三层级地理区域包括多个第二层级地理区域,如华北区域、东南区域、华南区域、西南区域等,每一个第二层级地理区域又可以划分为多个第一层级地理区域,以华南区域为例,该区域又可以划分为广东区域、广西区域、海南区域等,需要说明的是,上述区域的划分只是举例说明,实际应用时可以根据需要设置区域的划分规则,不一定按照行政区域划分。下一层级地理区域覆盖范围的总和等于上一层级区域的覆盖范围。
按照上述地理区域的层级分布设置服务器群组中服务器的层级分布。在第一层级地理区域部署第一级节点服务器,每一个第一层级地理区域设置至 少一台第一级节点服务器,以下内容中以一个第一层级地理区域设置一台第一级节点服务器为例,在广东区域、广西区域、海南区域等分别设置一台第一级节点服务器,在华南区域设置一台第二级节点服务器,则该第二级节点服务器为以上几台第一级节点服务器的上级节点服务器,以此类推,完成各个地理区域的服务器的部署。上述分布在各个区域的服务器构成服务器群组,该服务器群组的层级分布也呈树形,参照图2所示,为服务器群组中的服务器层级分布示意图。此外,可以将服务器群组中的任意一台服务器作为本实施例中的推流服务器的调度装置,可选地,将最高层级的服务器作为本实施例中的推流服务器的调度装置。
为服务器群组中各台服务器分配有IP地址,并且各台服务器的IP地址及其所在地理区域等数据均存储在调度服务器中。

步骤S40,将获取的IP地址发送至所述推流客户端,以供所述推流客户端根据所述IP地址将直播的流媒体文件推流至所述IP地址对应的第一级节点服务器。
将该第一级节点服务器的IP地址发送给推流客户端,推流客户端根据接收到的IP地址与上述第一级节点服务器建立连接,将直播的流媒体文件推流到该第一级节点服务器。观众观看该直播时,观众客户端直接从该服务器拉流。
本实施例提出的推流服务器的调度装置,预先配置服务器群组中服务器 的层级分布,该服务器群组中的服务器的层级分布与其所在的地理区域的层级分布一致,当接收到推流客户端的推流请求时,确定该推流客户端所在的地理区域,按照上述层级分布,获取服务器群组中与该地理区域对应的第一级节点服务器的IP地址,将该第一级节点服务器作为上述推流客户端的推流服务器,将上述IP地址发送给该推流客户端,该推流客户端将直播的流媒体文件推流至上述第一级节点服务器,上述推流服务器的调度方案按照地理区域的分布合理设置各级节点服务器的分布,能够根据该分布实现对推流服务器的快速调度,该方案就近将推流任务分配到各个地理区域的边缘节点服务器中,提高了推流服务器的调度精确度,进而提高了流媒体文件的上传速率的稳定性。

当检测到有预设数量的观众所在的地理区域不属于该流媒体文件的推流服务器所在的地理区域时,将所述流媒体文件迁移至该推流服务器的上一级节点服务器,并由该上一级节点服务器接收观众客户端发送的拉流请求。
本实施例中,观众客户端直接从推流服务器拉流,对于一个直播的流媒体文件来说,其观众可能分布在全国各地,当一个直播的观众大部分都不是分布在该直播的推流服务器所在的地理区域时,为了提高观众的下载流媒体文件的效率,将流媒体文件迁移至当前的徒留服务器的上一级节点服务器,迁移之后,有两个层级节点的服务器同时进行推流。迁移之前的观众仍然继续从原来的推理服务器上拉流,不影响观看直播,迁移后,由上述上一级节点服务器接收观众客户端发送的拉流请求。
