背景技术
当前，为网元的部署灵活性和管理性问题，业界提出了软件定义网络(software-defined networking，SDN)的概念。SDN通过将网元的控制逻辑和转发功能解耦，并将控制逻辑进行集中部署，使得对网络的控制和维护工作能够简单的通过对控制面设备的操作实现，从而提高网络的管理效率，并使得转发面设备更为简单化，有利于实现转发设备的高性能和可重用性。
现有SDN架构中的网元包括控制面设备和转发面设备，现有技术中，控制面设备和转发面设备执行对通告消息的处理，通告消息为报文的一种，一般具有以下特点：1、定期发送，即每过一段时间发送一次，2、同时发送给多个主机(HOST)，即通告消息的内容不是针对单个主机的，不需要事先和单个主机交互以发送通告消息。典型的通告消息包括IPV6协议定义的路由通告消息，802.11协议定义的灯塔beacon消息等。控制面设备维护一个定时器，定时器超时后向转发面设备发送分组输出消息，包含通告消息以及针对该通告消息的动作。转发面设备收到分组输出消息后，执行针对通告消息的动作，并以多播传输方式发送给多个主机。某个主机由于某种原因没有收到通告消息(比如在转发面设备发送通告消息是，主机没有开机)，主机可以选择不等待下一个通告消息的发送周期，而是立即发送通告请求消息。转发面设备接收通告请求消息，匹配转发规则，匹配成功后将通告请求消息发送给控制面设备。控制面设备受到通告请求消息后，触发发送通告消息，处理同上述发送消息至转发面设备的步骤，转发面设备进而发送通告消息。
由于通告消息是周期性发送的，每次发送至少需要一次控制面设备和转发面设备之间的信令交互。另外每次主机发送通告请求，也会额外导致控制面设备和转发面设备之间的信令交互。因此，如何降低控制面设备与转发面设备之间过多的信令交互，提高控制面和转发面设备的性能是当前亟需解决的问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简 称为“UMTS”)、全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)、无线局域网络(Wireless Local Area Networks，简称为“WLAN”)通信系统等。
图1示出了本发明实施例提供的网络架构图。本发明的其他实施例可参考本发明的网络架构图。
如图1所示，在由控制面设备和转发面设备组成的网络架构图中，
控制面设备负责根据报文特征(如IP五元组、以太网帧头)确定该业务流的转发动作(如转发、丢弃、修改报文头、封装、解封装等)，并通过将对应的流规则(包括流匹配信息，如IP五元组、以太网帧头等，和对应执行的动作)下发给转发面设备。转发面设备获取并存储该流规则，对于后续符合该流规则的报文，执行对应的动作，从而实现报文的转发或处理。
具体地，在采用SDN概念的无线局域网络WLAN网络中，控制面设备可以为接入控制器(Access Controller,简称为“AC”)，转发面设备可以为接入点(Access Point，简称为“AP”)，AC集中部署并生成beacon帧以简化AP的处理，beacon帧需要定期给STA(station)，使STA可以根据beacon帧获取WLAN网络的系统信息，并根据该信息接入网络或者调整自己的无线传输行为，其中STA相当于主机。
或者，在采用SDN概念的IPV6网络中，控制面设备可以为路由器控制器，转发面设备可以为接入路由器，路由器控制器维护可用的IPV6地址前缀信息以及IPV6地址前缀与接入路由器的绑定关系，并定期发送路由通告消息给Host，使得通过以太网与接入路由器连接的Host可以根据与该接入路由器绑定的IPv6前缀分配IP地址。在分配IP地址后，Host可以通过接入路由器发送和接受IPV6报文。在IPv6网络里，路由器控制器作为控制面设备存在，接入路由器作为转发面设备存在。

所述转发面设备状态包括所述转发面设备的缓冲区状态，时钟信息，端口状态中的至少一项。
由此，控制面设备可以将通告消息缓存到转发面设备，并指示转发面设备在发送前读取转发面设备状态并更新缓存的通告消息，从而避免了控制面设备发送通告消息前需要读取转发面设备状态导致的接口信令过多问题。避免了控制面设备和转发面设备之间过多的周期性的信令交互，从而提高了控制面设备和转发面设备的实现效率，提高控制面设备和转发面设备的性能。

图4示出了本发明实施例提供的一种通告消息处理方法，该方法可以由控制面设备和转发面设备执行，也可以由其他合适的装置，本发明对此并不限制。本发明实施例为图2和图3示出的本发明实施例的一个具体实施例。
如图4所示，该方法包括：
S401、控制面设备发送分组输出(packet out)消息至转发面设备。
该分组输出消息包括通告消息、缓存指示、定时器信息。
其中缓存指示信息用于指示转发面设备缓存通告消息，定时器信息用于指示转发面设备在定时器超时后发送缓存的通告消息至主机。
进一步地，所述分组输出消息还包括动作信息，指示转发面设备在发送通告消息时所需执行的动作。
S402、转发面设备缓存通告消息，并根据定时器信息设置定时器，定时器超时后，将缓存的通告消息发送给主机。
发送消息后，转发面设备重新根据定时器信息设置定时器。
主机接收到通告消息后，根据消息中的网络地址前缀自动分配IP地址。
S403、转发面设备在定时器再次超时后，将缓存的通告消息发送给主机。
因此，基于本发明实施例提供的方法，控制面设备发送分组输出消息中包括通告消息、缓存指示和定时器信息，使得缓存设备根据缓存指示消息缓存通告消息，根据定时器信息设置定时器，在定时器超时后，发送通告消息至主机，并设置定时器，在定时器再次超时后，再次发送通过消息。由此，控制面设备发送一个消息即可实现周期性通告消息发送，避免了 控制面设备和转发面设备之间过多的周期性的信令交互，从而提高了控制面设备和转发面设备的实现效率，提高控制面设备和转发面设备的性能。
本发明实施例之间的相关步骤可相互引用，本发明对此并不赘述。
图5示出了本发明实施例提供的一种通告消息处理方法的信令交互图，该方法可以由控制面设备和转发面设备执行，也可以由其他合适的装置，本发明对此并不限制。本发明实施例为图2和图3示出的本发明实施例的一个具体实施例。
如图3所示，该方法包括：
S501、控制面设备发送分组输出消息至转发面设备。
该消息包括通告消息、缓存指示、定时器信息。
具体可参考图4所示实施例中的相关步骤。
具体地，所述分组输出消息中还包括标识信息，用于标识该通告消息。
可选地，所述缓存指示中可以包含标识信息，用于标识该通告消息。
或者，转发面设备为通告消息分配标识，并发送分配的标识给控制面设备。
转发面设备可以缓存控制器发送的多个不同的通告消息，通过标识信息区分不同的通告消息。
S502、控制面设备发送流表修改消息至转发面设备。
具体地，该流表修改消息可以包括在上述分组输出消息中，或者控制器设备单独发送流表修改消息至转发面设备。
该消息用于指示转发面设备生成一个转发规则，该转发规则里的匹配内容用于匹配主机发送的通告请求消息，所述通告请求消息用于请求所述转发面发送所述标识对应所述通告消息。
S503、主机发送通告请求消息至转发面设备。
S504、转发面设备接收通告请求消息，匹配至上述生成的转发规则，根据转发规则中发送所述标识对应的通告消息至主机。
转发面设备在发送通告消息前，需要执行步骤501中控制面设备指示转发面设备在发送前所需执行的动作，在执行完动作后，发送给主机。需要注意的是由于该消息是匹配转发规则触发发送的，所以定时器不会重置。
因此，基于本发明实施例提供的方法，控制面设备可以将通告消息缓存至转发面设备，并指示转发面设备匹配特定类型的请求消息后发送缓存的通告消息，从而避免了须将特定类型的请求消息发送给控制面设备，由控制面设备发送通告消息导致的接口信令过多问题，避 免了控制面设备和转发面设备之间过多的周期性的信令交互，从而提高了控制面设备和转发面设备的实现效率，提高控制面设备和转发面设备的性能。
本发明实施例之间的相关步骤可相互引用，本发明对此并不赘述。
图6示出了本发明实施例提供的一种通告消息处理方法的信令交互图，该方法可以由控制面设备和转发面设备执行，也可以由其他合适的装置，本发明对此并不限制。本发明实施例为图2和图3示出的本发明实施例的一个具体实施例。
本实施例的场景为WLAN网络中beacon消息的处理。beacon消息也是通告消息的一种，其特征在于，一些特殊的beacon消息里包含转发面设备的一些状态信息，这些状态信息是动态变化的无法在控制面设备预先生成。这些特殊的beacon消息也是定期发送的，其周期为常规beacon消息(不包含转发面设备状态信息)的整数倍。(比如常规beacon帧每100毫秒发送1次，而特殊的beacon帧每300毫秒发送1次)。上述的通告消息也可以是其他通告消息，本发明对此并不限制。
具体地，如图6所示，该方法包括：
S601、控制面设备发送分组输出消息至转发面设备。
该分组输出消息中包括通告消息、缓存指示、定时器信息。
该通告消息可以是beacon消息。该通告消息也可能是其他消息，本发明对此并不限制。
该定时器信息可以用于指示转发面设备设置两个定时器(第一定时器和第二定时器)，在第一定时器超时后发送所述缓存的通告消息至所述主机。
可选地，该缓存指示用于指示转发面设备缓存该beacon消息，该定时器信息用于指示转发面设备设置第一定时器，在定时器超时后发送缓存的beacon消息。
该分组输出消息中还包括动作信息，该动作信息包括用于指示读取转发面设备状态和更新缓存的beacon消息。该转发面设备包括但不限于以下信息的一种或者几种：转发面设备特定缓冲区状态信息(如缓冲区内缓冲报文的目的MAC地址等)，转发面设备特定端口(包括无线端口)的状态信息(如端口是否拥塞等)，以及转发面设备的本地时钟信息等。更新缓存的beacon消息，即用上述状态值更新beacon消息，具体可以通过为beacon消息增添新参数或者修改beacon帧的现有参数来实现。在具体实现时可以采用避免转发面设备理解beacon消息方式，以修改现有参数为例，具体动作可以为，更新缓存的beacon消息的方法为将第X字节开始，长度为Y字节的内容更新为读取的状态信息。之所以避免转发面设备理解beacon消息方式，是为了减少转发面设备的智能性，避免转发面设备和特定通告消息绑定。
S602、第一定时器超时后，转发面设备发送缓存的beacon消息至主机。
转发面设备并执行对应的动作。
可选地，该缓存指示消息可用于转发面设备根据读取转发面设备状态和更新缓存的beacon消息，指示所述转发设备在第一定时器超时后，根据上述的动作信息发送更新的beacon消息至所述主机。
或者，所述定时器信息消息可用于指示转发面设备在第一定时器超时后，将所述转发面设备根据上述动作消息读取转发面设备状态后更新的的beacon消息发送给主机。
转发面设备重置定时器。
S603、第二定时器超时，转发面设备发送更新后的beacon消息至主机。
转发面设备根据动作信息，读取转发面设备的状态，更新缓存的beacon消息。例如，读取转发面设备缓存的下行报文的目的地址(即转发面设备特定缓冲区状态信息)，并根据这些目的地址设置缓存beacon帧的流量指示图(traffic indication map，TIM)参数，在更新缓存beacon消息后，再发送更新后的beacon消息至主机。
当休眠的主机接收到这些具有TIM参数的beacon消息后，会根据缓冲区状态结束休眠，从转发面设备接收缓存的报文。
某个时刻如果第一定时器和第二定时器同时超时，则执行时间长的那个定时器动作。
某些没有入网的主机在接收到beacon消息后，可以启动入网流程(association)。控制面设备和主机交互完成入网流程后，可能会修改beacon消息，比如在该主机加入前，所有其他主机都支持802.11n无线标准，而新加入的主机不支持802.11n无线标准，这种情况下控制面设备需要通过beacon消息通知其他主机修改自己的行为以适配新的主机。控制面设备发送新的分组输出消息，指示转发面设备更新缓存的beacon消息，该消息与步骤1里的分组输出消息都包含相同的缓冲消息标识，以使转发面设备能关联到步骤1的缓存消息。可选的控制面设备可以选择更新或者不更新缓存消息的定时器信息，如果控制面设备不更新定时器信息，则转发面设备不会重置定时器，原有定时器超时后，发送新的beacon消息，如果控制面设备更新定时器信息，则转发面设备会重置定时器，新的定时器超时后才发送新的beacon帧。同样控制面设备也可以选择更新或者不更新缓存消息的动作列表。
因此，基于本发明实施例提供的方法，控制面设备可以将通告消息缓存到转发面设备，并指示转发面设备在发送前读取转发面设备状态并更新缓存的通告消息，从而避免了控制面设备发送通告消息前需要读取转发面设备状态导致的接口信令过多问题。避免了控制面设备和转发面设备之间过多的周期性的信令交互，从而提高了控制面设备和转发面设备的实现效率，提高控制面设备和转发面设备的性能。
