Description

一种自适应流表的处理方法及装置 技术领域
本申请涉及无线通信技术领域，更具体的说是涉及一种自适应流表的处理方法及装置。
背景技术
软件定义网络(Software Defined Network,SDN)，是一种新型网络架构，其通过将网络设备的控制层与转发层分离开来，实现了网络流量的灵活控制，提高了网络的管理效率，为核心网络及应用的创新提供了良好的平台。
OpenFlow是实现软件定义网络的典型技术之一。基于OpenFlow技术的软件定义网络中的网元设备主要包括OpenFlow控制器(OpenFlow Controller)以及OpenFlow交换机(OpenFlow Switch)。其中OpenFlow交换机是核心组件，由OpenFlow协议、安全通道和流表三部分组成。OpenFlow交换机中可以包括一个或多个流表，流表由很多流表项组成，每一流表项即为一条流规则。流规则由控制器生成并下发至交换机中，交换机接收到数据时，通过将接收数据在流表中查询，进行流表匹配，根据匹配的流规则对数据执行相应的操作。
在未来通信网络中，数据业务种类越来越多，随之而来的是，各种不同的数据业务所需要的最有效的处理过程也各不相同，未来网络中的数据处理设备需要识别出不同的数据流，进而执行不同的处理过程。在无线通信网络中，可以借助Openflow的灵活性来扩展基站数据处理的灵活性。在数据处理中，引入了基于流表的数据处理技术，将接收到的数据包与流表中的规则进行匹配，进而寻址到合适的处理过程。
依照当前的流表规则匹配能力，在数据流达到6000～7000的时候，流表规则匹配的时间会耗时到达毫秒级，可能达到5毫秒。
在未来网络海量数据连接的场景下，例如：一个基站下，可能同时存在数以百万计的数据连接。在基站内部，这数以百万计的数据连接，会对应到相同 数量的数据流匹配规则，如果大量的流规则都保存在流表中等待数据包进行规则匹配，会造成时延，不能满足无线通信系统对数据处理时延的要求。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
由于现有的流表机制是基于互联网设计的，互联网中，数据包的到达时间是不可控的，流表只能预先在交换机保存，交换机被动的等待数据包达到，数据包到达之后再进行流规则匹配。
现有的无线通信网络的流表处理方法中，需要匹配的用户终端连接信息都完整的保存在流表中，例如：如图1A所示，在数据包到达基站的时候，从这个时间点开始，进行全局用户终端级流表的查询，在识别出该数据包所属的用户终端后，再查询该用户终端对应的业务级流表，从而识别出该数据包所属的业务流。然而，未来无线通信网络中，基站支持的用户终端连接数量非常庞大，而造成流表中的流规则数量巨大，在流规则匹配的过程中造成的时延无法满足无线通信的时延要求。
无线通信网络中，由于上行数据的传输是经过精密的控制的，在数据包达 到之前，网络中的设备，如：基站或基站控制器，可以获知下一时间段将传输的数据包的信息，例如：数据包所属的用户终端的信息；本发明提出了一种自适应流表的技术方案，将空口的资源调度过程与流表的调整进行结合，基于上行资源调度的结果，对流表中的流规则进行快速的更新调整。
一个具体实施例中，本发明自适应流表的处理方法包括：
无线接入设备进行资源调度，确定在被调度的时间段进行上行数据传输的用户终端或者数据流；
无线接入设备查询所述用户终端或者数据流的相应流规则，并将所述查询到的流规则更新到流表中；
当无线接入设备在所述被调度的时间段接收到数据包时，在所述流表中查询所述数据包对应的流规则，并根据所述数据包对应的流规则，对所述数据包进行相应的处理。
另一个具体实施例中，本发明自适应流表的处理方法包括：
无线接入设备接收无线接入设备控制器发送的流规则，所述流规则为无线接入设备控制器进行资源调度，确定在被调度的时间段进行上行数据传输的用户终端或者数据流后，查询的所述用户终端或者数据流的相应流规则；
所述无线接入设备将所述流规则更新到流表中；
当无线接入设备在所述被调度的时间段接收到数据包时，在所述流表中查询所述数据包对应的流规则，并根据所述数据包对应的流规则，对所述数据包进行相应的处理。
又一个具体实施例中，本发明自适应流表的处理方法包括：
无线接入设备接收无线接入设备控制器发送的用户终端或数据流的标识，所述用户终端或数据流的标识为无线接入设备控制器进行资源调度，确定的在被调度的时间段进行上行数据传输的用户终端或者数据流的标识；
无线接入设备根据所述用户终端或数据流的标识查询所述用户终端或者数据流的相应流规则，并将所述查询到的流规则更新到流表中；
当无线接入设备在所述被调度时间段接收到数据包时，在所述流表中查询所述数据包对应的流规则，并根据所述数据包对应的流规则，对所述数据包进 行相应的处理。
再一个具体实施例中，本发明自适应流表的处理方法包括：
无线接入设备控制器进行资源调度，确定在被调度的时间段进行上行数据传输的用户终端或者数据流后，查询所述用户终端或者数据流的相应流规则；
无线接入设备控制器向无线接入设备发送所述查询的流规则；以使得所述无线接入设备将所述流规则更新到流表中，当无线接入设备在所述被调度的时间段接收到数据包时，在所述流表中查询所述数据包对应的流规则，并根据所述数据包对应的流规则，对所述数据包进行相应的处理。
本发明实施例的自适应流规则处理系统包括流表、规则池和调度器三个功能单元，与现有技术不同的是，全部流规则放置于规则池中，并非全部放置到流表中；如图1B所示：在调度器完成上一次资源调度后，根据调度器调度的结果，确定被调度的传输时间段进行数据传输的用户终端或数据流，将所述用户终端或数据流对应的流规则从规则池中查询出来并更新到流表中，从而形成一个小规模的流表。而后当接收到数据包时，只根据形成的流表中的流规则进行查询，匹配到相应的流规则，进而对数据包进行相应的处理，由于流表规模较小，从而减少了数据在流表匹配过程中的时延。调度器每次调度完成后，基于规则池和调度器的调度结果，流表可以不断的进行更新，数据处理完成后，将上一次更新的流规则删除，从而保证流表不会过大。
无线通信系统主要包括无线接入设备及无线接入设备控制器，例如：基站BS(Base Station)及基站控制器BSC(Base Station Controller)，NodeB及无线网络控制器RNC(Radio Network Controller)；在一个具体实施例中，流表、规则池和调度器三个功能单元可以全部集成在无线接入设备中，例如：集成在基站或NodeB中，作为基站或NodeB的三个功能单元。
图1C为本申请实施例提供自适应流表控制系统的示意图，该实施例以流表、规则池和调度器三个功能单元集成在基站中为例进行说明，参考图1D，该自适应流表控制方法可以包括：
步骤101：基站完成一次资源调度后，确定被调度的时间段进行上行数据传输的用户终端或者数据流。
基站的调度器完成一次资源调度后，可以确定被调度的传输时间段会向基 站进行数据传输的用户终端或者数据流，用户终端及数据流均可为一个或多个，基站可以获知该用户终端或数据流的标识，如：用户终端的用户终端标识或数据流的连接标识。
步骤102，基站查询在所述被调度的时间段进行上行数据传输的用户终端或者数据流的相应流规则；
基站确定了被调度的传输时间段会向基站进行数据传输的用户终端或者数据流后，根据所述用户终端或数据流的标识在规则池中查询所述用户终端或数据流相应的流规则；例如：可以根据用户终端的用户终端标识或数据流的连接标识，在规则池中进行查询，进而得到被调度的传输时间段可能用到所述用户终端或数据流相应的流规则，查表的方式可以参考图1A的实施例。
步骤103，基站将所述查询到的流规则更新到流表中。
本步骤中，基站可以在被调度的传输时间段之前，在流表中写入所述查询到的流规则，可以包括用户终端或数据流的标识及相应的流规则；进一步的，可以将流表中已经存在的流规则删除，以确保流表不会过大而导致接收到数据包后查表时间过长。
流表可以有多种形式，例如：可以采用一级流表，根据终端或数据流的标识可以直接查询到相应的流规则，也可以采用图1A实施例所示的二级流表。
步骤104，基站在所述被调度的时间段接收到数据包时，基站根据所述数据包标识在所述流表中的进行查询，例如：根据数据包的用户终端标识或连接标识进行查询，得到所述数据包对应的流规则，然后根据流规则的指示对数据包进行相应的处理。
如果步骤103中形成的是二级流表，则查询的过程如图1A的实施例所示，先进行全局用户终端级流表的查询，在识别出该数据包所属的用户终端后，再查询该用户终端对应的业务级流表，从而识别出该数据包所属的业务流，从而得到相应的流规则。
步骤105，可选的，基站完成数据处理后，在流表中删除所述用户终端或数据流的相应的流规则。
基站可以在流表中删除所述用户终端或者数据流的相应流规则或清空流表中的流规则；或者，间隔几个调度周期或传输时间段后再在流表中删除所述 用户终端或者数据流的相应流规则或清空流表中的流规则。
上述实施例描述的是调度器与流表位于无线接入设备，如基站这一个物理实体时的设计。在一些分离实现的设计中，调度器可能不位于基站，而是位于无线接入设备控制器，如基站控制器，与流表不在一个物理实体上。
在一个具体实施例中，如图2A所示：调度器和规则池位于基站控制器，而流表位于基站时，参考图2B，所述自适应流表的处理方法包括：
步骤201：基站控制器完成一次资源调度后，确定被调度的时间段进行上行数据传输的用户终端或者数据流。
在基站控制器上的调度器完成一次资源调度后，可以确定被调度的传输时间段会向基站进行数据传输的用户终端或者数据流，用户终端及数据流均可为一个或多个，基站控制器可以获知该用户终端或数据流的标识，如：用户终端的用户终端标识或数据流的连接标识。
步骤202，基站控制器查询在所述被调度的时间段进行上行数据传输的用户终端或者数据流的相应流规则；
