Description

数据发送的方法、装置、系统、物理家庭网关及接入节点 技术领域
本文涉及但不限于通信领域，尤其涉及一种数据发送的方法、装置、系统、物理家庭网关及接入节点。
背景技术
家庭网关(Residential Gateway，简称为RG)是宽带接入家庭内部网络与外部网络连接的主要设备，随着网关功能的不断丰富，比如支持物联网功能，支持更为灵活的家庭设备发现等功能，但是运营商在之前部署的家庭网受到网关的处理能力限制而不能通过软件升级来支持新的功能。运营商将需要通过设备更新来支持新的业务，这个过程需要更换时间和花费更多的资源。
为了实现不更换原有网关，可以把较为复杂的功能在网络侧实现，包括通过把网关的部分功能虚拟化，在网络侧把多个用户的功能实现在一个物理设备上，上面运行家庭网关的虚拟功能部分，形成虚拟家庭网关功能，它与家庭内部的物理家庭网关设备一同形成一个完整的网关功能。如图1所示，在家庭内部的物理家庭网关设备与虚拟家庭网关之间建立一个连接通道来承载相关数据，机顶盒(Set Top Box，简称为STB)1到n连接到物理家庭网关设备，每个物理家庭网关设备与虚拟家庭网关之间建立一个通道，通道标识为1到n，通道标识可以依照建立通道技术而定，比如使用虚拟扩展局域网(Virtual eXtensible Local Area Network，简称为VXLAN)建立连接，则可以从VXLAN信息中得到通道标识，从而可以把家庭内部的物理家庭网关设备和虚拟家庭网关通过网络连接在一起，这个通道是从物理家庭网关通过接入节点、汇聚节点等设备到达虚拟家庭网关设备，每个用户一个单独的通道。
不管原有的物理家庭网关还是虚拟家庭网关，原有的相关功能还是需要支持的，比如上网，视频业务等。对于视频业务，为了节省带宽，组播技术被广泛采用，如果组播业务通过家庭内部的物理家庭网关设备和虚拟家庭网关之间的承载通道来传递，如图2所示，组播数据和组播协议都通过组播协议和数据流通道传递，虚拟家庭网关根据组播协议生成组播成员表，并从组播服务器接收到组播数据，通过组播协议和数据流通道1到n复制给物理家 庭网关。对于从物理家庭网关设备到虚拟家庭网关之间承载通道上的设备而言，组播业务就变成了单播业务了，这样对网络的带宽将带来巨大的压力。
针对上述问题，相关技术中并未提出有效的解决方案。

在一个可选的实施例中，利用预先建立的与组播服务器之间的第一组播数据通道接收来自组播服务器的组播数据包括：
利用预先建立的与第一组播服务器之间的组播数据通道接收的通过接入节点根据第一组播控制列表转发的来自组播服务器的组播数据；其中，第一组播数据通道通过接入节点连接物理家庭网关和虚拟家庭网关。在本实施例中，所有物理家庭网关与虚拟家庭网关之间都有一一对应的第一组播数据通道，且每条组播数据通道都会经过中间节点(包括上述的接入节点，可能还包括接入节点上游的汇聚节点等)。
在一个可选的实施例中，将上述组播数据发送给上述终端包括：确定配置的第二组播控制列表；根据第二组播控制列表将组播数据发送给上述终端。在本实施例中，第二组播控制列表可以包括组播成员控制列表和转发复制列表，其中，组播成员控制列表可以用于表示哪些成员是合法的组播成员(即，开通了组播权限的终端(例如，机顶盒))，转发复制列表可以用于表示组播数据的复制信息，即，需要复制几份。需要说明的是，开通组播权限的终端可以是变化的，开通了组播权限的终端请求播放组播节目的情况也是多变的，相应的，需要复制的组播数据的数量也是变化的，因此，上述第二组播控制列表可以根据终端的变化实时更新的。
在一个可选的实施例中，上述第二组播控制列表包括以下一种或多种：由配置服务器根据组播权限信息以及点播情况配置的第二组播控制列表；由上述虚拟家庭网关根据组播权限信息以及点播情况配置的第二组播控制列表；由虚拟家庭网关在根据组播权限信息以及点播情况确定了第二组播控制列表后发送给配置服务器，并由配置服务器配置的第二组播控制列表；其中，上述组播权限信息设置为表示两个以上终端的组播节目的点播权限，上述点播情况设置为表示两个以上终端点播组播节目的点播情况。在本实施例中，第二组播控制列表可以是由配置服务器配置的，可以是由虚拟家庭网关配置的，也可以是由配置服务器和虚拟家庭网关联合配置的。当然，在实际应用中，还可以通过其他合理的方式进行配置。
在一个可选的实施例中，根据上述第二组播控制列表将组播数据发送给上述终端包括：根据第二组播控制列表对组播数据进行复制；将复制后的组播数据发送给上述终端。在本实施例中，可以根据第二组播控制列表包括的组播控制成员列表确定哪些终端是合法的，即，哪些终端是具有组播节目的点播权限，再根据第二组播控制列表包括的转发复制列表确定组播数据需要复制的份数，在对组播数据进行了复制之后，便可以将复制后的组播数据发送给请求播放组播节目的终端。
由上述的实施例可知，第二组播控制列表可以根据终端的变化实时更新，下面对第二组播控制列表的更新进行举例说明：根据来自虚拟家庭网关和/或配置服务器的第一更新指示更新上述第二组播控制列表。在本实施例中，虚拟家庭网关可以接收到来自不同的终端的组播节目请求，虚拟家庭网关可以自己判断或者将不同的终端的组播节目请求发送给配置服务器进行判断是否需要更新物理家庭网关中的第二组播控制列表，以及在确定需要更新第二组播控制列表时，由虚拟家庭网关和/或配置服务器指示物理家庭网关更新第二组播控制列表。其中，判断的原则可以是与已有组播节目的转发复制列表判断物理家庭网关下的除请求播放组播节目的终端之外的别的终端是否点播过该组播节目，在判断结果为点播过的情况下，仅仅更新物理家庭网关的第二组播控制列表包括的转发复制列表即可。需要说明的是，当上述判断结果为其他终端没有点播过上述组播节目时，需要更新物理家庭网关上游节点的 组播控制列表。
在一个可选的实施例中，上述可承载组播协议的通道可以包括：基于媒体接入控制(MAC)层的二层通道、基于互联网网络之间互联协议(IP)层的三层通道。
本发明实施例还提供一种计算机存储介质，计算机存储介质中存储有计算机可执行指令，计算机可执行指令用于执行上述数据发送的方法。
在本实施例中还提供了一种数据发送的方法，图4是本发明实施例的数据发送的方法的流程图二，如图4所示，包括：
步骤402，利用预先建立的物理家庭网关与虚拟家庭网关之间的第二可承载组播协议的通道向组播服务器发送来自物理家庭网关的第三组播协议数据，和/或接收来自组播服务器的第四组播协议数据并将第四组播协议数据发送给物理家庭网关；
步骤404，利用预先建立的上述物理家庭网关与组播服务器之间的第二组播数据通道接收来自组播服务器的组播数据并将上述组播数据发送给物理家庭网关；其中，上述第二可承载组播协议的通道与第二组播数据通道是相互独立的。
其中，执行上述操作的可以是接入节点，上述步骤402和404的执行顺序可以是互换的。
通过上述步骤，由于传输组播协议数据(第三组播协议数据和第四组播协议数据)和传输组播数据的通道是互相独立的通道，因此，可以避免在同一条通道上发送组播协议数据和组播数据，降低了网络的带宽的压力，解决了相关技术中存在的网络带宽压力大的问题，进而达到了降低网络的带宽压力的效果。
在一个可选的实施例中，将上述组播数据发送给物理家庭网关包括：确定配置的第一组播控制列表；根据第一组播控制列表将上述组播数据发送给物理家庭网关。在本实施例中，第一组播控制列表可以包括组播成员控制列 表和转发复制列表，其中，组播成员控制列表可以用于表示哪些成员是合法的组播成员(即，开通了组播权限的终端(例如，机顶盒))，转发复制列表可以用于表示组播数据的复制信息，即，需要复制几份。需要说明的是，开通组播权限的终端可以是变化的，开通了组播权限的终端请求播放组播节目的情况也是多变的，相应的，需要复制的组播数据的数量也是变化的，因此，上述第一组播控制列表可以根据终端的变化实时更新的。
在一个可选的实施例中，上述第一组播控制列表包括以下一种或多种：由配置服务器根据组播服务器与物理家庭网关之间的网络连接情况配置的第一组播控制列表；由虚拟家庭网关根据组播服务器与物理家庭网关之间的网络连接情况配置的第一组播控制列表；由虚拟家庭网关在根据组播服务器与物理家庭网关之间的网络连接情况确定了第一组播控制列表后发送给配置服务器，并由配置服务器配置的第一组播控制列表。在本实施例中，第一组播控制列表可以是由配置服务器配置的，可以是由虚拟家庭网关配置的，也可以是由配置服务器和虚拟家庭网关联合配置的。当然，在实际应用中，还可以通过其他合理的方式进行配置。
在一个可选的实施例中，根据上述第一组播控制列表将组播数据发送给物理家庭网关包括：根据上述第一组播控制列表对组播数据进行复制；将复制后的组播数据发送给物理家庭网关。在本实施例中，可以根据第一组播控制列表包括的组播控制成员列表确定哪些终端是合法的，即，哪些终端是具有组播节目的点播权限，再根据第一组播控制列表包括的转发复制列表确定组播数据需要复制的份数，在对组播数据进行了复制之后，便可以将复制后的组播数据发送给物理家庭网关，之后物理家庭网关可以根据自己的第二组播控制列表将组播数据发送到连接的终端中。
在一个可选的实施例中，第一组播控制列表可以根据终端的变化实时更新，下面对第一组播控制列表的更新进行举例说明：根据来自虚拟家庭网关和/或配置服务器的第二更新指示更新第一组播控制列表。在本实施例中，虚拟家庭网关可以接收到来自不同的终端的组播节目请求，虚拟家庭网关可以自己判断或者将不同的终端的组播节目请求发送给配置服务器进行判断是否需要更新接入节点中的第一组播控制列表，以及在确定需要更新第一组播控 制列表时，由虚拟家庭网关和/或配置服务器指示物理家庭网关更新第一组播控制列表。其中，判断的原则可以是与已有组播节目的转发复制列表判断接入节点下的除请求播放组播节目的物理家庭网关之外，别的物理家庭网关是否请求点播过该组播节目，在判断结果为点播过的情况下，仅仅更新接入节点的第一组播控制列表包括的转发复制列表即可。需要说明的是，当上述判断结果为其他物理家庭网关没有点播过上述组播节目时，需要更新接入节点上游节点的组播控制列表。
在一个可选的实施例中，上述第二可承载组播协议的通道包括以下通道任意组合：基于媒体接入控制(MAC)层的二层通道、基于互联网IP层的三层通道。可以包括其中至少一个。
下面结合实施例对本发明进行说明：
在本发明实施例中提出了一种虚拟家庭网关的组播转发控制的方法，在该方法中，在物理家庭网关和虚拟家庭网关之间建立相对应的数据承载通道(对应于上述的可承载组播协议的通道)，从物理家庭网关连接的设备(例如，机顶盒)发出的组播协议包(即，组播协议数据)通过上述数据承载通道发送到虚拟家庭网关。
虚拟家庭网关与配置服务器交换组播成员控制列表相关信息，配置服务器根据标识信息来配置组播数据在转发路径上的设备的组播控制列表(其中，为物理家庭网关配置的组播控制列表对应于上述的第二组播控制列表，为接入节点配置的组播控制列表对应于上述的第一组播控制列表)；
或虚拟家庭网关形成物理家庭网关的组播成员控制列表，虚拟家庭网关为物理家庭网关配置组播控制列表；
或虚拟家庭网关发送组播控制列表给配置服务器，配置服务器为物理家庭网关配置对应的组播成员控制列表。
上述的数据承载通道可以是基于MAC层的二层或基于IP层的三层通道，同时承载数据业务和组播协议。
上述在物理家庭网关和虚拟家庭网关之间建立的数据承载通道(对应于上述的第二组播数据通道)与组播数据转发路径(对应于上述的第二组播数 据通道)可以不同(即，互相独立)，组播数据不承载在上述物理家庭网关和虚拟家庭网关之间建立的数据承载通道中，可以通过组播数据通道从组播服务器复制组播数据到接入节点并进一步复制到物理家庭网关。
配置服务器可以通过控制协议将配置的转发路径上的设备(例如，接入节点)的组播控制列表配置给转发路径上的设备，其中，上述的控制协议包括简单网络管理协议(SNMP)，客户终端设备(CPE)广域网管理协议(TR069)，OPENFLOW等其中的一个或多个协议。
配置服务器可以根据组播协议关联或添加的虚拟家庭网关的标识信息确定组播数据的复制节点，并更新组播的复制列表。
通过组播协议数据和组播数据的复制转发分离，并通过动态配置组播复制列表的方式，将有利于降低组播数据占用带宽的需求，并能够动态的控制组播的数据的复制转发。
本发明实施例还提供一种计算机存储介质，计算机存储介质中存储有计算机可执行指令，计算机可执行指令用于执行上述数据发送的方法。
实施例1：
如图5所示，在物理家庭网关和虚拟家庭网关之间建立相应的数据承载通道(即，建立物理家庭网关和虚拟家庭网关一对一的数据承载通道(第二可承载组播协议的通道))，这个通道穿越在物理家庭网关和虚拟家庭网关之间的网络节点(包括接入节点)，形成点到点的通道，从物理家庭网关连接的设备发出的组播协议包(对应于上述的第一组播协议数据)通过上述承载通道发送到虚拟家庭网关。
本发明实施例组播数据转发配置流程可以包括，由虚拟家庭网关把从组播服务器发送来的组播协议(对应于上述的第二组播协议数据)通过上述承载通道(第二可承载组播协议的通道)发送给物理家庭网关连接的设备，比如机顶盒，并记录组播成员信息的变化；虚拟家庭网关把从物理家庭网关连接的设备上接收的组播协议报文(对应于上述的第一组播协议数据)发送到 连接的上行接口给组播服务器，并记录组播成员信息的变化。或者，虚拟家庭网关与配置服务器一起根据本地组播权限列表(对应于上述的组播权限信息)以及对应组播节目被点播的情况(对应于上述的点播情况)确定组播数据如何复制，从而确定相应网络节点的组播成员控制列表。以机顶盒为例，图6是本发明实施例的组播数据转发配置流程图一；如图6所示，包括：
步骤602、机顶盒(STB)与组播服务器之间的组播协议在物理家庭网关和虚拟网关之间通道发送，由虚拟网关生成组播成员控制列表的信息；
步骤604、虚拟网关和配置服务器之间的交互包含组播成员控制列表的信息；
步骤606、配置服务器配置组播服务器和机顶盒之间的设备的组播成员控制列表。
虚拟家庭网关可以与配置服务器交换组播成员控制列表相关信息，比如某个物理家庭网关连接的机顶盒1申请加入了某个组播组，那么虚拟家庭网关可以根据虚拟家庭网关与物理家庭网关之间的组播协议通道(也就是图5中的通道1)的信息可以确定组播复制目标设备，比如根据组播协议接收的通道1可以确定连接的是接入节点(Access Node，简称为AN)对应的端口1，并进一步确定了端口1连接的目标设备是连接物理家庭网关的设备，知道这些信息后，虚拟家庭网关把包含组播成员控制列表的信息发送给配置服务器，组播成员控制列表的信息包括比如接入节点1的端口1连接的物理家庭网关，配置服务器根据组播服务器与物理家庭网关设备的位置确定组播数据的转发路径，并生成从组播服务器到物理家庭网关设备之间个设备的组播数据的转发复制列表。从而，组播数据就从组播服务器复制到物理家庭网关，并进一步复制到连接的机顶盒。
一个接入节点可以连接多个物理家庭网关设备，以及物理家庭网关设备后连接的机顶盒，如果机顶盒1准备点播一个组播节目，那么如果机顶盒n已经点播过这个节目，虚拟家庭网关设备接收到组播节目请求后，发送给配置服务器，配置服务器可以对比相关技术中的组播节目的转发复制列表(该列表可以位于配置服务器中，该列表用于记录所有的组播数据的复制情况)，发现机顶盒n已经点播过该节目，那么配置服务器只是更新接入节点的组播 复制列表即可。如果该接入节点连接的物理家庭网关都没有点播过该节目，则需要更新接入节点上连设备的组播数据的转发复制列表。
组播数据将从组播服务器到机顶盒进行逐级的复制，从而实现组播的数据有效复制，组播数据的转发路径是根据组播数据流的合理节省带宽的方式构建，而不是到虚拟家庭网关处集中复制，节省网络带宽。
其中的组播协议承载通道(对应于上述的组播协议通道，第二可承载组播协议的通道)可以是基于MAC层的二层或基于IP层的三层通道。
上述组播协议承载通道与组播数据转发路径不同，组播数据不承载在组播协议承载通道中。
配置服务器可以使用控制协议将配置的组播成员控制列表配置给转发路径上的每一个设备，上述控制协议可以包括SNMP，TR069，OPENFLOW等协议的任意组合，可以包括其中至少之一。
实施例2：
如图5所示，在物理家庭网关和虚拟家庭网关之间建立相应的数据承载通道(第二可承载组播协议的通道)，这个通道穿越在物理家庭网关和虚拟家庭网关之间的网络节点，形成点到点的通道，从物理家庭网关连接的设备(如机顶盒)发出的组播协议包通过上述承载通道发送到虚拟家庭网关。
图7是本发明实施例的组播数据转发配置流程图二；如图7所示，包括：包括：
步骤702、机顶盒与组播服务器之间的组播协议在物理家庭网关与虚拟家庭网关之间的通道进行发送，由虚拟网关生成组播成员控制列表的信息；
步骤704、虚拟家庭形成物理家庭网关的组播成员控制列表；可以包括：虚拟家庭网关接收到组播协议报文后，可以完成互联网组播管理协议探测(IGMP Snooping)的功能，形成物理家庭网关的组播成员控制列表。
这个列表可以通过两种方式配置到物理家庭网关上，第一种方法参照步骤7062；第二种方法参照7082；
步骤7062、虚拟网关配置物理家庭网关对应的组播成员控制列表；
步骤7082、虚拟网关把组播转发成员控制列表发送给配置服务器；
步骤7084、配置服务器配置物理家庭网关对应的组播成员控制列表等列表。
在组播服务器和机顶盒之间的网络节点，除了物理家庭网关，相应的网络节点具备识别IGMP等组播协议报文的能力，形成该节点的组播复制列表信息，如果组播成员控制列表，从而完成组播数据的复制，由于物理家庭网关不识别组播协议包，所以物理家庭网关上的组播复制控制是通过外部控制或配置实现的，如图7的方式。
虚拟家庭网关与配置服务器可以交换组播成员控制列表相关信息，比如某个物理家庭网关连接的机顶盒申请加入了某个组播组，那么虚拟家庭网关根据物理家庭网关的那个接口加入了某个组播来决定组播数据的转发复制行为。
组播数据将从组播服务器到机顶盒进行逐级的复制，从而实现组播的数据有效复制，组播数据的转发路径是根据组播数据流的合理节省带宽的方式构建，而不是到虚拟家庭网关处集中复制，节省网络带宽。
其中的组播协议承载通道(第二可承载组播协议的通道)可以包括基于MAC层的二层或基于IP层的三层通道。
上述组播协议承载通道(第二可承载组播协议的通道)与组播数据转发路径可以不同，组播数据不承载在组播协议承载通道中。
上述配置服务器可以通过控制协议将配置的组播成员控制列表配置给物理家庭网关，上述的控制协议包括简单网络管理协议(SNMP)，TR069，OPENFLOW等协议的任意组合，可以包括其中至少一个。
