背景技术
SDN(Software Defined Networking，软件定义网络)是当前网络领域的热点，被业界普遍视作未来网络的演进方向。SDN倡导的标准化控制协议、软件化网络接口为资源的统一管理、业务的推陈出新提供了很好地支持，能够为用户提供更好的网络体验，提升了网络的价值。无线运营商也希望在自身的无线通讯设备中集成SDN设备，提供SDN能力，提升本身的无线设备的网络价值。
SDN控制器是承载SDN控制层业务的设备，负责对底层的SDN设备进行统一控制，以及向上层业务应用提供网络能力调用，SDN网络中必须部署SDN控制器。而无线基站设备的部署有自身的特点，通常是根据覆盖要求将基站设备部署在相应的地区，然后通过传输设备连接到核心网。如果单纯在基站侧部署SDN控制器，则无法对大量基站侧的SDN设备进行统一管理，因此目前一般采用在放置在网络远端的中心机内房部署SDN控制器，以用于对各基站上的SDN设备进行管理。采用这种部署管理方式会存在以下问题：(1)基站上电初期没有和远端的机房建立连接，这个时候远端的SDN控制器无法管理基站侧的SDN设备；(2)基站上如果有需要SDN控制器来进行转发的报文，需经由远端的SDN控制器转发，路径较远，性能低下；(3)如果基站和机房侧的传输链路中断，则SDN控制器对该基站上的SDN设备的管理也将失效，可靠性较低。

附图概述

图2为本发明实施例二提供的通信***结构示意图。
本发明的实施方式
本发明实施例通过同时在网络远端节点(可以是中心机房)和网络近端节点(例如基站等)上同时设置SDN控制器，并通过两侧设置的SDN控制器联合实现对网络近端节点侧SDN设备进行管理，能提升SDN设备管理的 可靠性和性能。下面通过具体实施方式结合附图对本申请作进一步详细说明。
实施例一：
请参见图1所示，本实施例中软件定义网络管理方法包括：
步骤101：在网络远端节点布置中心软件定义网络控制器，在网络近端节点上布置本地软件定义网络控制器；
步骤102：中心软件定义网络控制器和网络近端节点上的本地软件定义网络控制器联合对网络近端节点上的软件定义网络设备进行管理。例如，在网络近端节点上电初期或与核心网断链等其他未能与网络远端节点的中心软件定义网络控制器连接时，可直接通过本地布置的本地SDN控制器实现对本地SDN设备的管理，提升SDN设备管理的可靠性；又例如，当网络近端节点需要通过SDN控制器进行报文转发时，可直接选用本地SDN控制器转发，并不需要先将报文发送到网络远端节点，再经由网络远端节点的SDN控制器转发，因此可以提升转发效率和性能。
上述步骤101中，在网络近端节点上布置本地软件定义网络控制器时，包括将网络近端节点上软件定义网络设备的管理参数配置到该网络近端节点的本地软件定义网络控制器上。本实施例中软件定义网络设备的管理参数包括但不限于配置信息、设备能力信息、链路信息和拓扑信息中的至少一种。
在本实施例中，在网络近端节点上布置本地软件定义网络控制器后，网络近端节点上电后，也即网络近端节点运行过程中，网络近端节点上的本地软件定义网络控制器在检测到网络近端节点上软件定义网络设备的管理数据有改变时，获取更新改变后的管理数据。
本实施例中，在网络远端节点布置中心软件定义网络控制器也许将网络近端节点上软件定义网络设备的管理参数配置到中心软件定义网络控制器上。本实施例中网络远端节点还可布置核心网设备。核心网设备和中心软件定义网络控制器可以使用以太网进行连接通信，也可以处于不同子网，通过IP网络进行通信。本实施例中可直接通过网络近端节点上的各软件定义网络设备直接或通过核心网设备将相关管理参数发给中心软件定义网络控制器进行配置；还可直接利用网络近端节点上的本地软件定义网络控制器实现将网 络近端节点上各软件定义网络设备的管理参数直接或通过核心网设备发给网络远端节点的中心软件定义网络控制器，因为本地软件定义网络控制器具有网络近端节点上各软件定义网络设备的管理参数，这样可以提升配置效率并提升资源利用率。通过网络近端节点上的本地软件定义网络控制器将网络近端节点上软件定义网络设备的管理参数发给中心软件定义网络控制器包括：
在网络近端节点上电且与中心软件定义网络控制器连接后，网络近端节点上的本地软件定义网络控制器将网络近端节点上软件定义网络设备的管理参数发给所述中心软件定义网络控制器；此时的管理参数是各软件定义网络设备初始时设定的管理参数。在网络近端节点正常运行过程中，各软件定义网络设备的管理参数可能会发生变化，此时网络近端节点上的本地软件定义网络控制器还可将获取的网络近端节点上软件定义网络设备改变后的管理参数也发给中心软件定义网络控制器进行更新。
网络远端节点的中心软件定义网络控制器通过上述方式获取到各网络近端节点上的软件定义网络设备的管理参数后，即可以实现对网络近端节点上的软件定义网络设备的管理参数进行控制。各网络近端节点本地的软件定义网络控制器也具有本地各软件定义网络设备的管理参数，因此也可以实现对网络近端节点本地各软件定义网络设备的管理。本实施例中中心软件定义网络控制器、各网络近端节点上各软件定义网络控制器都具有自己的通信地址，且软件定义网络控制器之间的通信地址各不相同；相应的业务软件可通过对应的通信地址(例如IP)访问到对应的软件定义网络控制器从而发起网络服务请求。本实施例中网络近端节点上的业务软件可通过网络近端节点上对应的软件定义网络设备将网络服务请求发给对应的软件定义网络控制器。
根据上述分析可知，本实施例中网络远端节点的中心软件定义网络控制器和网络近端节点侧的本地软件定义网络控制器都具备软件定义网络设备管理功能。因此可根据不同的应用场景有效联合二者对软件定义网络设备进行管理可以提升管理的可靠性、稳定性以及灵活性。下面分别以几种应用场景为示例进行说明。
网络近端节点初始上电时，此时网络近端节点还未同网络远端节点的核心网设备建立连接，也即还未与网络远端节点的中心软件定义网络控制器建 立连接，此时网络近端节点上的本地软件定义网络控制器在网络近端节点上电过程中，对该网络近端节点的软件定义网络设备进行管理。且在网络近端节点上电过程中，网络近端节点上相关业务软件的网络服务请求(也即SDN网络服务请求)也可通过本地软件定义网络控制器进行处理，也即网络近端节点上的本地软件定义网络控制器在网络近端节点上电过程中还可用于对相关业务软件的网络服务器请求进行处理。在网络近端节点上电完成且与网络远端节点的中心软件定义网络控制器建立连接后，网络近端节点的本地软件定义网络控制器将网络近端节点上软件定义网络设备的管理参数同步给中心软件定义网络控制器。
在网络近端节点正常运行过程中，网络近端节点上的本地软件定义网络控制器在该网络近端节点侧的报文需通过软件定义网络控制器转发时，优先对该报文进行转发；也即网络近端节点侧的报文需要通过软件定义网络控制器转发报文时，采用优选采用网络近端节点上的本地软件定义网络控制器进行转发的转发策略，当本地软件定义网络控制器转发所述报文失败时，再采用网络远端节点的中心软件定义网络控制器对该报文进行转发。这样可以提升转发效率。
网络近端节点上电正常运行过程中，当网络近端节点侧本地运行的业务软件有网络服务请求时，优选采用网络近端节点上的本地软件定义网络控制器对该网络服务请求进行处理；当本地软件定义网络控制器处理失败时，再采用网络远端节点的中心软件定义网络控制器对该网络服务请求进行处理。本实施例中无线网络近端节点侧的本地软件定义网络只管理本网络近端节点上的软件定义网络设备，不管理其他网络近端节点上的软件定义网络设备。
网络近端节点正常运行过程中，当需要对多个网络近端节点上的软件定义网络设备同时配置时，中心软件定义网络控制器需发给多个网络近端节点的软件定义网络设备的配置信息下发给多个网络近端节点实现对多个网络近端节点的统一管理。
网络近端节点正常运行过程中，网络近端节点与中心软件定义网络控制器音传输等问题断开连接时，网络近端节点上的本地软件定义网络控制器对网络近端节点上的软件定义网络设备进行管理；并在网络近端节点与中心软 件定义网络控制器重新连接时，将网络近端节点上软件定义网络设备的管理数据再同步到中心软件定义网络控制器上；以使中心软件定义网络控制器可以实现对该网络近端节点上软件定义网络设备的控制。
本实施例在网络近端节点侧和网络远端节点同时部署软件定义网络控制器，与相关技术相比，提高了软件定义网络控制的稳定性，可以大规模的统一管理无线网络近端节点侧的软件定义网络设备，还可以解决网络近端节点本地业务软件对软件定义网络网络的服务请求。
实施例二：
本实施例提供了一种无线通信***，请参见图2所示，包括：布置于网络远端节点1的核心网设备11和中心软件定义网络控制器12(也即中心软件定义网络控制器12设置在网络远端节点)，以及布置在网络近端节点2上的本地软件定义网络控制器21；中心软件定义网络控制器12和网络近端节点2上的本地软件定义网络控制器21设置为联合对所述网络近端节点2上软件定义网络设备进行管理。核心网设备11和中心软件定义网络控制器12可以使用以太网进行连接通信，也可以处于不同子网，通过IP网络进行通信。
本实施例中网络近端节点2上的本地软件定义网络控制器21可以是轻量型软件定义网络控制器；网络远端节点的中心软件定义网络控制器12则是大容量的软件定义网络控制器。
网络近端节点2上的本地软件定义网络控制器21上配置有网络近端节点2上软件定义网络设备的管理参数；本实施例中软件定义网络设备的管理参数包括但不限于配置信息、设备能力信息、链路信息和拓扑信息中的至少一种。且网络近端节点2上的本地软件定义网络控制器21在网络近端节点上电后，也即网络近端节点运行过程中，检测到网络近端节点上软件定义网络设备的管理数据有改变时，获取更新改变后的管理数据。
中心软件定义网络控制器12上配置有各网络近端节点2上软件定义网络设备的管理参数。本实施例中可直接通过网络近端节点2上的各软件定义网络设备通过与核心网通信将相关管理参数发给中心软件定义网络控制器12进行配置；还可直接利用网络近端节点上的本地软件定义网络控制器将网络近端节点上各软件定义网络设备的管理参数直接发给网络远端节点的中心软 件定义网络控制器。
本实施例中，中心软件定义网络控制器12和网络近端节点2上的本地软件定义网络控制器21对网络近端节点2的软件定义网络设备进行管理包括：
网络近端节点初始上电时，此时网络近端节点2还未同网络远端节点的核心网建立连接，也即还未与网络远端节点的中心软件定义网络控制器12建立连接，此时网络近端节点2上的本地软件定义网络控制器21在网络近端节点2上电过程中，对该网络近端节点2的软件定义网络设备进行管理。且在网络近端节点2上电过程中，网络近端节点上相关业务软件的网络服务请求(也即SDN网络服务请求)也可通过本地软件定义网络控制器21进行处理，也即网络近端节点上的本地软件定义网络控制器21在网络近端节点2上电过程中还可设置为对相关业务软件的网络服务器请求进行处理。在网络近端节点上电完成且与网络远端节点的中心软件定义网络控制器12建立连接后，网络近端节点2的本地软件定义网络控制器21将网络近端节点2上软件定义网络设备的管理参数同步给中心软件定义网络控制器12。
在网络近端节点2正常运行过程中，网络近端节点2上的本地软件定义网络控制器21在该网络近端节点2侧的报文需通过软件定义网络控制器转发时，优先对该报文进行转发；也即网络近端节点2侧的报文需要通过软件定义网络控制器转发报文时，采用优选采用网络近端节点2上的本地软件定义网络控制器21进行转发的转发策略，当本地软件定义网络控制器21转发所述报文失败时，再采用网络远端节点的中心软件定义网络控制器12对该报文进行转发。这样可以提升转发效率。
网络近端节点2上电正常运行过程中，当网络近端节点2侧本地运行的业务软件有网络服务请求时，优选采用网络近端节点2上的本地软件定义网络控制器21对该网络服务请求进行处理；当本地软件定义网络控制器21处理失败时，再采用网络远端节点的中心软件定义网络控制器12对该网络服务请求进行处理。本实施例中无线网络近端节点2侧的本地软件定义网络只管理本网络近端节点2上的软件定义网络设备，不管理其他网络近端节点2上的软件定义网络设备。
网络近端节点2正常运行过程中，当需要对多个网络近端节点2上的软 件定义网络设备同时配置时，中心软件定义网络控制器12将来自核心网需发给多个网络近端节点2的软件定义网络设备的配置信息下发给多个网络近端节点2实现对多个网络近端节点2的统一管理。
网络近端节点2正常运行过程中，网络近端节点2与中心软件定义网络控制器12音传输等问题断开连接时，网络近端节点2上的本地软件定义网络控制器21对网络近端节点2上的软件定义网络设备进行管理；并在网络近端节点2与中心软件定义网络控制器12重新连接时，将网络近端节点2上软件定义网络设备的管理数据再同步到中心软件定义网络控制器12上；以使中心软件定义网络控制器12可以实现对该网络近端节点2上软件定义网络设备的控制。
下面以网络远端节点为无线运营商机房，网络近端节点为无线基站的应用为例进行示例说明。
假设在某一区域根据无线用户数量和覆盖需求，在各个地区分散部署了100个无线基站，在该区域的无线运营商机房放置了核心网设备。部署软件定义网络控制器时，在每个无线基站侧都部署一个本地软件定义网络控制器，在该地区的无线运营商机房部署一个大软件定义网络控制器，也即中心软件定义网络控制器。
设地点A的基站设备开始加电，在上电初期，该基站设备运行软件版本需要隔离基站外部和内部的报文，需要给外网和内外报文添加不同的VLAN(Virtual Local Area Network，虚拟局域网)标识，这个需求通过本地软件定义网络控制器下发流表给本地的软件定义网络设备实现。上电完成后，基站设备跟机房建立了网络连接，机房侧的中心软件定义网络控制器将该地点A基站的软件定义网络设备纳入管理。
在各基站正常运行过程中，当需要给该区域所有的无线基站的外网口进行流量带宽配置，这个需求通过机房侧的中心软件定义网络控制器统一下发带宽配置规则给该地区所有的无线基站侧的软件定义网络设备实现。
假设地点B的基站设备跟机房的网络连接断，也即与中心软件定义网络控制器断链，则由该基站侧本地软件定义网络控制器管理本地的软件定义网络设备，待跟机房的网络恢复，基站侧本地软件定义网络控制器重新将本 地的软件定义网络管理数据同步到远端的中心软件定义网络控制器，远端的中心软件定义网络控制器重新管理地点B基站侧的软件定义网络设备。
