背景技术
通信领域，例如涉及一种宽带接入网中，宽带接入网关设备(Broadcast Network Gateway/Virtual Broadcast Network Gateway，BNG/vBNG)用户流量灵活调度的处理方法、装置和系统
随着软件定义网络(Software Defined Network，SDN)技术和网络功能虚拟化(Network Function Virtualization，NFV)技术的发展，城域网从传统以网络为核心的架构向以数据中心为核心的网络架构演进。传统的网元设备也从专业化朝着通用化演进。传统网元设备从专业化朝着通用化演进主要解决两个解耦：控制与转发的解耦、软件与硬件的解耦。
BNG在用户宽带接入业务和场景中非常重要。对BNG设备在用户接入上的主要要求是用户认证、接入控制、以及流量调度等。随着各种互联网业务的层出不穷，对BNG设备支持的用户的会话数要求不断提高、对用户接入带宽不断提高、例如对BNG设备对外提供业务开放、可编程的能力的要求越来越高。基于这些因素，BNG设备非常有必要基于SDN/NFV的架构实现上文提到的两个解耦。
BNG转发与控制的解耦是一种趋势，转发与控制解耦后，控制面可以管理多个转发面，进行多个转发面之间用户、流量、以及资源的灵活调度，和单机相比设备的利用率和可靠性都能得到大幅的提升。但是，在BNG转发与控制解耦后如何通过简化的用户接入端口配置实现用户宽带接入处理，是亟待解决的技术问题。

在控制与转发分离的BNG环境下，一个BNG/vBNG控制面管理几十、上百个BNG/vBNG转发面，一个BNG/vBNG转发面上的用户接入端口平均可以达到100个，那么一个BNG/vBNG控制面就需要管理几千甚至上万个用户接入端口，这些接口的配置量巨大，因此，如何在用户宽带接入时简化控制面用户接入端口配置是亟待解决的技术问题。针对该技术问题，本申请提出了如下的技术方案，可通过简化的BNG/vBNG用户接入端口配置实现用户宽带接入处理。

下面对本申请技术方案进行详细说明。
实施例一
本实施例提供一种用户宽带接入处理的方法，可通过BNG/vBNG实现，可适用于支持用户宽带接入业务的网络架构。
如图2所示，所述用户宽带接入处理的方法可以包括：步骤201和步骤202。
在步骤201中，在BNG/vBNG-C预先配置VLAN模板接口，所述VLAN模板接口包含至少一个VLAN模板子接口，所述至少一个VLAN模板子接口与宽带接入的业务类型一一对应。
在步骤202中，利用所述VLAN模板接口对来自BNG/vBNG-U的协议报文进行接入处理。
在本实施例中，通过在BNG/vBNG-C配置虚拟局域网(Virtual Local Area Network，VLAN)模板接口完成用户宽带接入的业务处理，从而简化了BNG/vBNG控制面用户接入端口配置，实现了BNG/vBNG-U用户接入端口的免配置，并以此配置实现了BNG/vBNG对用户带宽接入过程中相关协议报文的处理，不仅简化了宽带接入端口配置，而且可实现BNG/vBNG上用户接入端口配置与用户宽带接入业务的自适应，对周边网络没有额外的要求，成本低，同时又提升了运维效率。
在本实施例中，VLAN模板接口是一种配置，VLAN模板接口与物理接口没有任何关联。VLAN接口是在物理接口下创建的子接口。
在本实施例中，利用所述VLAN模板接口对来自BNG/vBNG-U的协议报文进行接入处理的方式可以有多种。
一种实现方式中，所述利用所述VLAN模板接口对来自BNG/vBNG-U的协议报文进行接入处理，包括：将来自BNG/vBNG转发面BNG/vBNG-U的协议报文与所述至少一个VLAN模板子接口进行匹配处理；针对与所述至少一个VLAN模板子接口相匹配的所述协议报文，进行接入处理。这里，所述利用所述VLAN模板接口对来自BNG/vBNG-U的协议报文进行接入处理，还可以包括：在所述协议报文与所述至少一个所述VLAN模板子接口中的每一个不匹配时，丢弃所述协议报文。
这里，协议报文与所述VLAN模板子接口的匹配处理可以包括但不限于：将协议报文内的VLAN标签(tag)与VLAN模板子接口的覆盖范围进行匹配，如果协议报文内的VLAN tag在VLAN模板子接口的覆盖范围内则表示两者匹配，如果协议报文内的VLAN tag不在VLAN模板子接口的覆盖范围内则表示 两者不匹配。
在本实施例中，所述针对与所述至少一个VLAN模板子接口相匹配的所述协议报文进行接入处理，可以包括：在所述协议报文与任意所述VLAN模板子接口相匹配时，对所述协议报文执行所述VLAN模板子接口对应业务类型的接入处理。比如，所述协议报文相匹配的VLAN模板子接口对应HSI时，则将所述协议报文执行HSI的接入处理。再比如，所述协议报文相匹配的VLAN模板子接口对应IPTV时，则将所述协议报文执行IPTV的接入处理。
在本实施例中，所述利用所述VLAN模板接口对来自BNG/vBNG-U的协议报文进行接入处理之前，还可以包括：在协议报文与所述BNG/vBNG-U上其他所有VLAN子接口都不匹配时，所述BNG/vBNG-U通过在用户接入端口上预置的子接口接收所述协议报文，并将所述协议报文送至所述BNG/vBNG-C。
实际应用中，BNG/vBNG-U的端口上设置有VLAN子接口，可以通过这些VLAN子接口传送协议报文。在本实施例中，在BNG/vBNG-U上的用户接入端口上预先生成一个默认的子接口，该子接口设置为将与其他所有VLAN子接口都不匹配的协议报文送至BNG/vBNG-C，该子接口覆盖其他VLAN接口之外的VLAN范围。如此，对于用户宽带接入处理相关的协议报文都会通过该子接口传送到BNG/vBNG-C，BNG/vBNG-C即可针对这些协议报文执行相应的接入处理。
一种实现方式中，所述将所述协议报文送至所述BNG/vBNG-C，可以包括：所述BNG/vBNG-U将所述协议报文封装在虚拟可扩展局域网(virtual Extensible LAN，vxlan)隧道并通过所述vxlan隧道将所述协议报文送到所述BNG/vBNG-C。实际应用中，通过vxlan可透传二层报文。
一种实现方式中，所述利用所述VLAN模板接口对来自BNG/vBNG-U的协议报文进行接入处理之前，还包括：在所述BNG/vBNG-C上针对所述BNG/vBNG-U指定端口上的指定VLAN进行单独配置，并将所述协议报文与所述指定VLAN的单独配置进行匹配处理；所述利用所述VLAN模板接口对来自BNG/vBNG-U的协议报文进行接入处理，包括：在所述协议报文与所述指定VLAN的单独配置不匹配时，利用所述VLAN模板接口对来自BNG/vBNG-U的协议报文进行接入处理。
这里，针对所述BNG/vBNG-U指定端口上的指定VLAN进行单独配置是指对所述BNG/vBNG-U指定端口上的指定VLAN单独配置相应的VLAN子接口， 该VLAN子接口是在所述BNG/vBNG-U指定端口下创建的子接口，其VLAN范围与所述指定VLAN匹配。
如图3所示，为本实施例上述方法的示例性实现流程。一种实现方式中，如图3所示，本实施例用户宽带接入处理方法的执行过程可以包括如下步骤301至步骤304。
在步骤301中，BNG/vBNG-U在所有用户接入物理端口默认生成一个子接口，该子接口用于宽带业务接入。用户基于以太网的点对点协议(Point to Point Protocol over Ethernet，PPPoE)、基于上网用户的物理位置(Internet Protocol over Ethernet，IPoE)拨号协议报文在接入网络OLT/SW打上VLAN/QinQ tag，BNG/vBNG-U转发面根据PPPoE、IPoE协议报文中的VLAN/QinQ tag进行VLAN查找匹配，未匹配用户接入端口上其他子接口VLAN的PPPoE、IPoE协议报文将匹配该默认生成的子接口，封装vxlan隧道发送给BNG/vBNG-C控制面。
在步骤302中，BNG/vBNG-C根据预先设置的VLAN模板接口，根据宽带接入业务类型创建VLAN模板子接口，每个VLAN模板子接口匹配一种业务，并设置该业务的VLAN范围。
在步骤303中，BNG/vBNG-C针对BNG/vBNG-U某些用户接入端口的特殊VLAN接入，在BNG/BNG-C控制面针对该转发面的接口做单独配置。
在步骤304中，BNG/vBNG-C收到的协议报文优先匹配为特定用户面(User Plane，UP)单独配置的子接口VLAN，如果匹配不到则继续匹配VLAN模板子接口，匹配到的报文进行该宽带业务的处理，未匹配到的协议报文丢弃。
这里，对于匹配到单独配置的子接口VLAN的协议报文，可以直接根据该子接口VLAN对应的指定VLAN配置进行协议处理，不再继续匹配vlan模板子接口。
如图4所示，为本实施例中用户宽带接入处理方法的示例性交互时序图。
其中，BNG/vBNG-C包括用户表管理模块、控制报文解封装模块、PPPoE/DHCP协议处理模块、以及VLAN查找模块。用户表管理模块设置为实现BNG/vBNG-C上的用户表管理，控制报文解封装模块设置为实现BNG/vBNG-C上控制报文的解封装等处理，PPPoE/DHCP协议处理模块设置为实现BNG/vBNG-C上的PPPoE/DHCP协议处理，VLAN查找模块设置为实现BNG/vBNG-C上VLAN子接口或VLAN模板子接口与协议报文(如，控制报文) 的匹配处理。
其中，BNG/vBNG-U包括用户表管理模块、控制报文封装模块、以及VLAN查找模块。用户表管理模块设置为实现BNG/vBNG-U上的用户表管理，VLAN查找模块设置为实现BNG/vBNG-U上接口VLAN与协议报文(如，控制报文)的匹配处理，控制报文封装模块设置为实现BNG/vBNG-U上控制报文的封装等处理。
其中，用户设备通过OLT/SW发送PADI/DHCP DiscoverV到BNG/vBNG-U-1，BNG/vBNG-U的VLAN查找模块对该PADI/DHCP Discovery进行匹配处理找到合适的接口VLAN、再由控制报文封装模块封装到VxLAN隧道，经由VxLAN隧道送至BNG/vBNG-C，BNG/vBNG-C的控制报文解封装模块对该PADI/DHCP Discovery进行解封装、在由VLAN查找模块进行匹配处理，最后得到PADI/DHCP-Offer，PADI/DHCP-Offer经由VxLAN隧道送至BNG/vBNG-U，BNG/vBNG-U将PADI/DHCP-Offer再返回给用户设备。
一种实现方式中，基于图4所示的时序图，本实施例用户宽带接入处理方法的示例性执行过程可以包括如下步骤一至步骤七。
步骤一，BNG/vBNG-U用户接入端口默认生成子接口，该子接口用于宽带接入。
步骤二，BNG/vBNG-C预先设置VLAN模板接口，根据宽带接入的业务类型创建VLAN模板子接口，每个VLAN模板子接口匹配一种业务，并设置该业务的VLAN范围；此外，BNG/vBNG-C针对BNG/vBNG-U某些用户接入端口的特殊VLAN接入，在BNG/BNG-C控制面针对该转发面的接口做单独配置。
步骤三，BNG/vBNG-U对用户接入端口收到的控制报文进行接口VLAN匹配，未匹配到子接口VLAN的控制报文通过所述默认的子接口走隧道封装发送给BNG/vBNG-C。
其中，BNG/vBNG-U与BNG/vBNG-C之间的隧道为VxLAN隧道。在BNG/vBNG-U需要进行隧道的封装。
步骤四，BNG/vBNG-C通过VxLAN隧道收到从BNG/vBNG-U发送过来的控制报文，解封装。
步骤五，BNG/vBNG-C根据特定UP接入端口子接口VLAN对接收到的控制报文进行VLAN匹配，对匹配到的控制报文进行相应协议的接入处理；对未匹配的报文再进行VLAN模板子接口匹配。
步骤六，BNG/vBNG-C根据VLAN模板子接口，对接收到的控制报文进行VLAN匹配，只回应匹配到VLAN的控制报文。
步骤七，BNG/vBNG-C通过openflow向BNG/vBNG-U下发用户表项，接入后续的用户。
下面以一个示例为例说明本实施例用户宽带接入方法的示例性实现方式。需要说明的是，下文实例仅为示例性说明，并非用于限制本申请，实际应用中，本实施例用户带宽接入方法还可以有其他的实现方式。
示例1
如图5所示，为本示例的网络架构示意图，该网络架构中BNG/vBNG通过简化后的用户接入端口配置实现用户宽带接入处理。如图5所示，在BNG/vBNG-C上预先配置有VLAN模板接口vlantemp1，VLAN模板接口vlantemp1配置为如下：
子接口模板1(Interface vlantemp1)
绑定BNG转发面名称(bind BNG-U)name/all
子接口模板1.1(Interface vlantemp1.1)
接入高速上网业务(description for his-service)
VLAN范围：内层VLAN范围，外层VLAN范围(qinq range internal...external...)
子接口模板1.2(Interface vlantemp1.2)
接入交互式网络电视(Internet Protocol Television，IPTV)业务(description for iptv)
VLAN范围：内层VLAN范围，外层VLAN范围(qinq range internal...external...)
其中，根据宽带接入业务类型，该VLAN模板接口vlantemp1上创建有两个VLAN模板子接口，分别是：Interface vlantemp1.1和Interface vlantemp1.2。其中，Interface vlantemp1.1与高速宽带上网(High Speed Internet，HSI)业务相对应，Interface vlantemp1.2与IPTV业务相对应，如上文中VLAN模板接口vlantemp1的配置中包含了这些VLAN模板子接口对应的业务、以及业务范围。
如图5所示的网络架构中，BNG/vBNG转发面池化场景中包含多个BNG/vBNG-U，分别为：BNG/vBNG-U-1、BNG/vBNG-U-2、......、BNG/vBNG-N，N为不小于2的整数。其中，每个BNG/vBNG-U上都包含两个用户接入端口， 分别为：P 1、P 2、P 3、P 4、......、P N-1、P N。P 1、P 2为BNG/vBNG-U-1的用户接入端口，P 3、P 4为BNG/vBNG-U-2的用户接入端口，P N-1、P N为BNG/vBNG-N的用户接入端口。
如口图5所示，BNG/vBNG-U-1～BNG/vBNG-U-N的用户接入端口为P 1～P N，每个用户接入端口均默认生成一个子接口，该子接口用于传送用户宽带接入业务相关的协议报文。
如图5所示的网络架构中，当BNG/vBNG-U用户接入端口收到控制报文，先进行其他子接口VLAN(即除所述默认的子接口之外的子接口)匹配，如果匹配到就走非用户接入流程，如果没有匹配到，就进行默认子接口匹配，走用户接入流程。
如图5所示的网络架构中，BNG/vBNG-U对匹配默认子接口的控制报文进行vxlan隧道封装，发送给BNG/vBNG-C控制面；
如图5所示的网络架构中，当BNG/vBNG-C收到控制报文，可以根据特定UP接入端口子接口VLAN对接收到的控制报文进行VLAN匹配，对匹配到的控制报文进行相应协议的接入处理；对未匹配的报文再进行VLAN模板子接口匹配。
如图5所示的网络架构中，BNG/vBNG-C对未匹配特定UP接入端口子接口VLAN的控制报文根据VLAN模板子接口进行VLAN匹配，回应匹配到VLAN的控制报文，未匹配的报文丢弃。
如图6所示，为本示例的用户宽带接入处理流程示意图，适用转发面池化场景。如图6所示，本示例中用户宽带接入处理的过程可以包括：步骤601至步骤605。
在步骤601中，BNG/vBNG-U-1在用户接入端口P 1和用户接入端口P 2上分别默认生成一个子接口，该子接口用于用户宽带接入业务。
在步骤602中，BNG/vBNG-C针对BNG/vBNG-U-1预先配置VLAN模板接口，并根据BNG/vBNG-U-1承载的宽带业务类型设置两个VLAN模板子接口，分别负责高速上网(HSI)和IPTV业务接入，设置对应的VLAN范围。
在步骤603中，BNG/vBNG-U-1的用户接入端口P 1和用户接入端口P 2收到PPPoE和IPoE协议报文，可以进行用户接入端口P 1和用户接入端口P 2上其余子接口VLAN匹配，未匹配的报文封装为vxlan报文送到BNG/vBNG-C。
在步骤604中，BNG/vBNG-C对协议报文进行VLAN模板子接口的VLAN 匹配。匹配vlantemp1.1接口VLAN的报文进行HSI业务接入，匹配vlantemp1.2接口VLAN的报文进行因特网协议电视(Internet Protocol Television，IPTV)业务接入。
在步骤605中，BNG/vBNG-C对未匹配VLAN模板子接口VLAN的协议报文进行丢弃。
