Description

处理报文的方法、装置和系统
本申请要求于2015年06月10日提交中国专利局、申请号为201510315577.6、发明名称为“处理报文的方法、装置和系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域

背景技术
目前，已知一种网络架构，在该网络中包括多个节点，每个节点综合考虑携带于接收的报文中的信息，例如，媒体访问控制(英文：Media Access Control，简称：MAC)层、网际协议(英文：Internet Protocol，简称：IP)层及传输控制协议(英文：Transmission Control Protocol，简称：TCP)等层中的信息，确定对报文的处理策略，并根据该处理策略对该报文进行处理。上述方式能够支持根据多个协议层的信息来决定对报文如何处理，从而能够扩展处理策略的匹配维度，实现处理策略灵活配置。例如，即使报文1和报文2的MAC层的信息(例如，源MAC地址或目的MAC地址)相同，但在报文1和报文2的IP层信息(例如，源IP地址或目的IP地址)不同的情况下，仍能够实现为报文1和报文2配置不同的处理策略。
但是，在该处理中，各节点需要探测报文的多个协议层才能够获知上述处理策略，处理繁杂，计算量较大，严重影响了报文的转发效率，降低了系统的吞吐量。

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一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的技术方案，可以应用于各种通信系统，例如：全球移动通讯系统(英文：Global System of Mobile communication，简称：GSM)，码分多址(英文：Code Division Multiple Access，简称：CDMA)系统，宽带码分多址(英文：Wideband Code Division Multiple Access Wireless，简称：WCDMA)，通用分组无线业务(英文：General Packet Radio Service，简称：GPRS)，长期演进(英文：Long Term Evolution，简称：LTE)等。
图1示出了从控制设备角度描述的根据本发明一实施例的处理报文的方法100的示意性流程图，如图1所示，该方法100包括：
S110，控制设备确定目标业务的传输路径，其中，该传输路径包括至少两个处理节点。
S120，该控制设备为该传输路径上的每个处理节点分别生成处理策略，其中，每个处理策略用于指示对应的处理节点在目标业务的传输路径中的下一跳。
S130，该控制设备向每个处理节点发送为该处理节点生成的处理策略与该目标业务的业务标识之间的映射关系。
该映射关系用于使接收到携带有该目标业务的业务标识的报文的处理节点基于所述处理节点接收的映射关系，确定对应的处理策略，并根据该处理策略，对该报文进行处理，其中，该业务标识是该控制设备为该目标业务分配的，用于唯一地标识该目标业务。
例如，如图2所示，在通信系统中，发送端通过多个处理节点(例如，图2所示的处理节点1～处理节点7中的部分或全部)及各转发设备之间的物理链路(例如，光纤)将报文发送至接收端。
并且，作为实例而非限定，该发送端可以是基站设备，该接收端可以是无线网络控制器(英文：radio network controller，简称：RNC，radio network  controller)、信令网关(英文：signaling gateway，SGW，)或移动性管理实体(英文：mobility management entity，简称：MME)。此情况下，该多个处理节点可以是承载网络中的转发节点，或者说路由节点等。
即，当基站接收到来自用户设备(英文：User Equipment，简称：UE)所访问的业务的报文(或者说，上行数据)后，需要通过承载网络(例如，图2中虚线所示路径)将该报文包传输至RNC、SGW或MME。同样，RNC、SGW或MME需要将用户设备所访问的业务的报文(或者说，下行数据)通过承载网络传输至基站，进而由基站将该报文包传输至用户设备。
如上所说，在基站和RNC、SGW或MME之间传输的报文需要经由多个处理节点所组成的传输路径，该传输路径上的各处理节点需要获知针对该报文的处理策略，以确定如何对该报文进行处理。
应理解，以上列举的承载网络仅为适用本发明的处理报文的方法的通信系统的示例性说明，本发明并未限定于此，其他在发送端设备和接收端设备之间传输的业务需要经由多个处理节点转发的通信系统均落入本发明的保护范围内。
为了便于理解和说明，以下将根据本发明实施例的处理报文的方法适用于承载网络时的处理过程为例进行说明。
另外，需要说明的是，根据应用场景的不同，上述处理节点也可以为虚拟机或转发设备等。
该方法100的执行主体可以是用于管理承载网络的控制设备，并且该控制设备可以与承载网络中的节点通信。并且，在本发明实施例中，该控制设备可以独立配置，也可以集成在其他网元(例如，某个节点)中。
在本发明实施例中，各处理节点根据来自控制设备的处理策略对各业务的报文进行处理，例如，将该报文通过处理策略中记载的端口，传输至该处理策略指示的该处理节点在该报文的传输路径中的下一跳。
因此，在S110，控制设备可以确定目标业务的传输路径，例如，控制设备可以确定该传输路径所包括的处理节点，以及各处理节点之间的关系，例如，一个处理节点在该传输路径上的下一跳是哪个处理节点。
在本发明实施例中，包括目标业务在内的各业务的传输路径可以由网络管理员或服务供应商预先通知并存储在控制设备中。
或者，控制设备也可以通过获取目标业务的报文，并对该报文进行解析 或探测，从而获知该报文的路由信息，例如，源MAC地址、目的MAC地址、源IP地址、源端口、目的IP地址、目的端口、通信连接的协议类型和统一资源定位器地址(URL，Uniform Resource Locator)中的一种或多种，并且，可以根据该路由信息，确定该传输路径，并且，根据路由信息确定业务的传输路径的方法和过程可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
在本发明的具体实现方式中，所述获取目标业务的报文的方法可以通过如下过程实现：
由于各处理节点需要根据来自控制设备的处理策略对各业务的报文进行处理，因此，当来自发送端的目标业务的首个报文到达该传输路径中的首个处理节点(例如，图2所示的处理节点1)时，位于该首个处理节点无法查找到与该报文相对应的处理策略(随后对该查找方法和过程进行详细说明)，即，可以确定未从控制设备获得针对该目标业务的报文的处理策略，从而，该首个处理节点将该目标业务的首个报文传输至控制设备，由此，控制设备能够获取该目标业务的报文。
应理解，以上列举的控制设备获取目标业务的报文的方法仅为示例性说明，本发明并不限定于此，其他能够使控制设备获得目标业务的报文的方法均落入本发明的保护范围内。
并且，以上列举的控制设备确定目标业务的传输路径的方法和过程仅为示例性说明，本发明并不限定于此，例如，处理节点也可以将目标业务的报文的路由信息等能够用于确定目标业务的传输路径的信息传输给控制设备，从而，控制设备能够直接根据所接收到的信息确定传输路径。
在S120，控制设备对于如上所述确定的目标业务的传输路径所包括的各处理节点分别生成对应的处理策略。
在本发明实施例中，处理策略可以用于指示各处理节点在目标业务的传输路径中的下一跳，从而，各处理节点可以根据该处理策略，将该目标业务的报文传输至该传输路径中的下一跳。
在本发明实施例中，一个处理节点对应的处理策略可以包括该处理节点传输该目标业务的报文所使用的转发端口，该转发端口与该处理节点在传输路径中的下一跳相对应，即，该处理节点通过该转发端口发送出的报文能够到达该处理节点在传输路径中的下一跳。
应理解，以上列举的处理策略所包括的具体信息仅为示例性说明，本发明并不限定于此，其他能够使处理节点将报文传输至下一跳的信息或参数均落入本发明的保护范围内。
在S130，控制设备可以将如上所述确定的各处理节点对应的处理策略分别下发至各处理节点。
在本发明实施例中，可能存在多种业务同时存在的情况，此情况下，为了能够使各处理节点准确确定各业务对应的处理策略，控制设备可以为各业务分别分配业务标识，以使一个业务的业务标识用于唯一的标识该业务，并将各业务的业务标识与各业务对应的处理策略之间的映射关系(例如，映射关系表项)下发至各处理节点，从而，处理节点能够根据报文所携带的业务标识查找到上述映射关系表象中与该业务标识相对应的处理策略。
在本发明中可以采用以下方式在报文中添加控制设备所分配的业务标识，即，可以由该控制设备在报文中添加业务标识(即，方式1)，可以由传输路径中的首个节点在报文中添加业务标识(即，方式2)，下面，分别对以上两种方式进行详细说明。
方式1
可选地，该方法还包括：
该控制设备接收第一处理节点发送的该目标业务的报文，该第一处理节点是该传输路径中的首个节点；
该控制设备在该目标业务的报文中添加该目标业务的业务标识；
该控制设备将添加了该目标业务的业务标识的报文发送至该第一处理节点。
具体地说，在本发明实施例中，业务标识可以由控制设备添加，因此，当目标业务的报文到达该传输路径中的首个处理节点(即，第一处理节点)时未携带有控制设备所分配的业务标识，因此，可以预先协商或规定：各处理节点在接收到未携带有控制设备下发的处理策略中包括的业务标识的报文时(以下，为了便于理解和区分，称为原始报文)，需要将该原始报文发送至控制设备。
从而，当未经由控制设备添加业务标识的该目标业务的报文到达该传输路径中的首个处理节点时，该首个处理节点无法从该报文中探测到该目标业务的业务标识，该首个处理节点按预先协商或规定将该报文传输至控制设 备，控制设备可以根据该报文的路由信息，确定该报文所属于的业务(即，上述目标业务)，并将该目标业务的业务标识添加在该报文中，返回给该首个处理节点。
由此，在传输路径中传输的报文携带了目标业务的业务标识，从而，各处理节点能够根据如上所述从控制设备获取的处理策略，对接收的报文进行处理(例如，转发等)。
需要说明的是，在本发明实施例中，根据控制设备确定各处理节点的处理策略(或者说，控制设备确定传输路径)的方式，该报文的传输路径中的首个处理节点向控制设备传输未携带有业务标识的报文的时机可以是在控制设备向该首个处理节点下发控制策略之前，也可以是在控制设备向该首个处理节点下发控制策略之后。
例如，当传输路径由网络管理员或服务供应商预先通知并存储在控制设备中时，在未携带有业务标识的报文到达该传输路径中的首个处理节点之前，控制设备已经能够确定该报文所属业务的传输路径，并根据该传输路径确定首个处理节点的处理策略，此情况下，该报文的传输路径中的首个处理节点向控制设备传输未携带有业务标识的报文的时机可以是在控制设备向该首个处理节点下发控制策略之后。
再例如，当控制设备通过获取报文的路由信息，并根据该路由信息确定该业务的传输路径时，业务的首个报文到达传输路径中的首个处理节点时，控制设备尚未完成该首个处理节点的处理策略的下发，此情况下，该报文的传输路径中的首个处理节点向控制设备传输未携带有业务标识的报文的时机可以是在控制设备向该首个处理节点下发控制策略之前。
方式2
可选地，第一处理节点对应的第一处理策略还用于指示该第一处理节点在该目标业务的报文中添加该目标业务的业务标识，该第一处理节点是该传输路径中的首个节点，其中，该第一处理策略与该目标业务的路由信息相对应，以便于该第一处理节点根据该目标业务的路由信息确定该第一处理策略，该路由信息包括以下至少一种：源媒体访问控制MAC地址、目的MAC地址、源网际协议IP地址、源端口、目的IP地址、目的端口、通信连接的协议类型和统一资源定位器地址。
具体地说，在如上所述确定的针对该传输路径的首个处理节点的处理策 略中，还可以指示首个处理节点在接收到携带有规定的路由信息(即，目标业务对应的路由信息，例如，源MAC地址、目的MAC地址、源IP地址、源端口、目的IP地址、目的端口、通信连接的协议类型或URL)的报文时，在该报文中添加该目标业务的业务标识。
从而，当未添加业务标识的该目标业务的报文到达该传输路径中的首个处理节点时，该首个处理节点能够根据该报文所携带的路由信息，确定该报文属于目标业务，并根据从控制设备获取的处理策略，在该报文中添加该目标业务的业务标识。
由此，在传输路径中传输的报文携带了目标业务的业务标识，从而，各处理节点能够根据如上所述从控制设备获取的处理策略，对接收到的报文进行处理(例如，转发等)。
在本发明实施例中，由于上述业务标识是控制设备分配并由控制设备或处理节点添加的，为了避免该业务标识对通信系统中的其他设备(例如，接收端等)解析报文时造成影响，可以在携带有业务标识的报文完成在传输路径中的转发并离开传输路径中的最后一个节点之前，将该业务标识从报文中删除。
在本发明中可以采用以下方式从报文中删除控制设备所分配的业务标识，即，可以由该控制设备从报文中删除业务标识(即，方式3)，也可以由传输路径中的最后一个节点从报文中删除业务标识(即，方式4)，下面，分别对以上两种方式进行详细说明。
方式3
可选地，该方法还包括：
该控制设备接收第二处理节点发送的该目标业务的报文，该第二处理节点是该传输路径中的最后一个节点；
该控制设备将该目标业务的业务标识从该目标业务的报文中删除；
该控制设备将删除了该目标业务的业务标识的报文发送至该第二处理节点。
具体地说，在本发明实施例中，控制设备可以在针对该传输路径中的最后一个节点(即，第二处理节点)的处理策略中指示该最后一个节点在收到携带有该目标业务的业务标识的报文后，将该报文传输至控制设备，并指示该最后一个节点在接收到该控制设备返回的报文后，将根据处理策略所记载 的方式对该报文进行处理。
从而，当携带有目标业务的业务标识的该目标业务的报文到达该传输路径中的最后一个节点时，该最后一个节点可以根据该业务标识确定该目标业务对应的处理策略，并根据该处理策略的指示，将该报文传输至控制设备，控制设备在接收到携带有业务标识的报文时，可以将该业务标识删除，并将删除了业务标识后的报文传输至该传输路径中的最后一个节点，由此，离开传输路径的报文不会携带业务标识。
方式4
可选地，第二处理节点对应的第二处理策略还用于指示该第二处理节点将该目标业务的业务标识从该目标业务的报文中删除，该第二处理节点是该传输路径中的最后一个节点。
具体地说，在本发明实施例中，控制设备可以在针对该传输路径中的最后一个节点(即，第二处理节点)的处理策略中指示该最后一个节点在收到携带有该目标业务的业务标识的报文后，将该业务标识删除，并根据处理策略所记载的方式对该报文进行处理。
从而，当携带有目标业务的业务标识的该目标业务的报文到达该传输路径中的最后一个节点时，该最后一个节点可以根据该业务标识确定该目标业务对应的处理策略，并根据该处理策略的指示，将该业务标识删除，由此，离开传输路径的报文不会携带业务标识。
下面，对本发明实施例中业务标识在报文中的添加位置进行详细说明。
可选地，该业务标识携带于报文的用于承载目的MAC地址的字段。
具体地说，在本发明实施例中，由于目标业务的报文在各处理节点中的处理策略是基于业务标识来确定的，因此，无需使用原本承载于报文的目的MAC地址字段中的信息(即，目的MAC地址)，如图3所示，添加业务标识的设备(处理节点或控制设备)在报文中添加业务标识时，可以将承载于报文中的目的MAC地址替换为控制设备所分配的业务标识。
需要说明的是，在本发明实施例中，该目标业务的业务标识与该目标业务的目的MAC地址可以相同也可以不同，只要各处理节点能够预先获知承载于该目的MAC地址字段中的信息作为业务标识即可。
可选地，该业务标识携带于报文的用于承载源IP地址的字段；
具体地说，在本发明实施例中，由于目标业务的报文在各处理节点中的 处理策略是基于业务标识来确定的，因此，无需使用原本承载于报文的源IP地址字段中的信息(即，源IP地址)，从而，添加业务标识的设备(处理节点或控制设备)在报文中添加业务标识时，可以将承载于报文中的源IP地址替换为控制设备所分配的业务标识。
需要说明的是，在本发明实施例中，该目标业务的业务标识与该目标业务的源IP地址可以相同也可以不同，只要各处理节点能够预先获知承载于该目的源IP地址字段中的信息作为业务标识即可。
可选地，该业务标识携带于报文的用于承载目的IP地址的字段，其中，该目标业务的业务标识与该目标业务的目的IP地址不同；
具体地说，在本发明实施例中，由于目标业务的报文在各处理节点中的处理策略是基于业务标识来确定的，因此，无需使用原本承载于报文的目的IP地址字段中的信息(即，目的IP地址)，从而，添加业务标识的设备(处理节点或控制设备)在报文中添加业务标识时，可以将承载于报文中的目的IP地址替换为控制设备所分配的业务标识。
需要说明的是，在本发明实施例中，该目标业务的业务标识与该目标业务的目的IP地址可以相同也可以不同，只要各处理节点能够预先获知承载于该目的IP地址字段中的信息作为业务标识即可。
应理解，以上列举的由业务标识所替换的原本承载于报文中的信息仅为实例性说明，本发明并不限定于此，其他不影响报文在各处理节点之间传输的信息均被删除并替换为业务标识。例如，作为实例而非限定，还可以列举IP选项、TCP选项、TCP确认号、TCP序列号、源端口或目的端口等信息。
即，可选地，该业务标识携带于报文的用于承载IP选项的字段；或该业务标识携带于报文的用于承载传输控制协议TCP选项的字段；或该业务标识携带于报文的用于承载传输控制协议TCP确认号的字段；或该业务标识携带于报文的用于承载传输控制协议TCP序列号的字段；或该业务标识携带于报文的用于承载源端口的字段；或该业务标识携带于报文的用于承载目的端口的字段。
需要说明的是，在本发明实施例中，该目标业务的业务标识与上述信息可以相同也可以不同，只要各处理节点能够预先获知上述信息的承载字段中的信息作为业务标识即可。
可选地，该业务标识携带于报文的以太层。
具体地说，在本发明实施例中，可以使用报文中尚未分配的空闲字段添加业务标识，例如，如图4所示，可以在报文的以太层规定用于承载业务标识的字段，根据以太层的信息承载规则，该承载业务标识字段可以由以太类型字段和承载字段构成，作为实例而非限定，在本发明实施例中，可以将业务标识的以太类型定义为0xAAB0，并在承载字段添加业务标识。
下面，以将该方法应用于图2所示承载系统时各设备的动作为例，对该方法100的处理流程进行示例性说明。
设处理节点1的MAC地址为0x112233445566(其中，“0x”表示该MAC地址为16进制，为了避免赘述，以下省略对相同或相似情况的说明)，从而，发送端可以将处理节点1的MAC地址作为该目标业务的报文的目的MAC地址，承载于报文的目的MAC地址字段，并发送至处理节点1。
来自发送端的目标业务的报文经过以下传输路径到达接收端，即：
处理节点1→处理节点5→处理节点7→处理节点6→处理节点3。
A、处理节点1的处理过程
如果该报文是目标业务是首个报文，则处理节点1中可能未存储控制设备所下发的针对该目标业务的处理策略，此情况下，处理节点1将该目标业务的首个报文或该报文的路由信息发送至控制设备，控制设备获取报文的路由信息并计算该目标业务的转发的路径为处理节点1→处理节点5→处理节点7→处理节点6→处理节点3，为该目标业务分配业务标识，并向上述各处理节点下发处理策略，例如，针对处理节点1的处理策略可以包括当接收到承载有该目标业务的路由信息的报文时，在该报文中添加业务标识，并通过该处理策略所指定的端口(例如，以下表1中指示的端口)发送该报文。并且，控制设备可以将该报文返回给处理节点1。
从而，处理节点1中能够存储控制设备所下发的针对该目标业务的处理策略，该处理策略可以是以下表1所示的映射关系表项。
表1
Figure PCTCN2016078930-appb-000001
从而，处理节点1可以根据该报文的路由信息(例如，源MAC地址、目的MAC地址、源IP地址、源端口、目的IP地址、目的端口、通信连接 的协议类型或URL)确定在进行针对该目标业务的报文的处理时使用的处理策略为上述表1所示的：增加业务标识(0x000000000ABC)，并通过转发端口10发送该报文。
这里，处理节点1可以根据图3或图4的方式添加业务标识，即，可以将报文的目的MAC地址、目的IP地址或源IP地址替换为业务标识，或者，也可以在报文的以太层添加业务标识，。
另外，如果该报文不是目标业务的首个报文，则处理节点1中已存在控制设备所下发的针对该目标业务的处理策略(例如，上述表1)，从而，当报文到达处理节点1时，处理节点1可以根据该报文的路由信息确定针对该目标业务的报文的处理策略。
例如，在将报文的目的MAC地址替换为业务标识时，进入处理节点1时报文的MAC地址是0x112233445566，通过处理节点1的业务标识添加动作，目的MAC地址变为了0x00000000000ABC。虽然目的MAC地址字段(或者说，域)没有消失，但是目的MAC地址字段所表征的含义已经变更。后续的处理节点5、处理节点7、处理节点6、处理节点3将根据报文的目的MAC地址0x000000000ABC确定对应的处理策略。
需要说明的是，以上列举说明的处理节点1添加业务标识的方式，但本发明并不限定于此，也可以由控制设备添加，或者也可以由控制设备添加目标业务的首个报文的业务标识，并由处理节点1添加后续报文的业务标识，。
B、处理节点5的处理过程
处理节点5中能够存储控制设备所下发的针对该目标业务的处理策略，该处理策略可以是以下表2所示的映射关系表项。
表2
索引 策略
报文所承载的业务标识 输出端口：150
从而，处理节点5可以获取报文中携带的业务标识，例如，可以是承载于报文的目标MAC地址字段中的信息(例如，如上所述由处理节点1添加的0x000000000ABC)，并根据该业务标识基于表2查找到针对该报文的处理策略：通过转发端口150发送该报文。
C、处理节点7的处理过程
处理节点7中能够存储控制设备所下发的针对该目标业务的处理策略， 该处理策略可以是以下表3所示的映射关系表项。
表3
索引 策略
报文所承载的业务标识 输出端口：13
从而，处理节点7可以获取报文中携带的业务标识，例如，可以是承载于报文的目标MAC地址字段中的信息(例如，如上所述由处理节点1添加的0x000000000ABC)，并根据该业务标识基于表3查找到针对该报文的处理策略：通过转发端口13发送该报文。
D、处理节点6的处理过程
处理节点6中能够存储控制设备所下发的针对该目标业务的处理策略，该处理策略可以是以下表4所示的映射关系表项。
表4
索引 策略
报文所承载的业务标识 输出端口：22
从而，处理节点6可以获取报文中携带的业务标识，例如，可以是承载于报文的目标MAC地址字段中的信息(例如，如上所述由处理节点1添加的0x000000000ABC)，并根据该业务标识基于表4查找到针对该报文的处理策略：通过转发端口22发送该报文。
E、处理节点3的处理过程
处理节点3中能够存储控制设备所下发的针对该目标业务的处理策略，该处理策略可以是以下表5所示的映射关系表项。
表5
Figure PCTCN2016078930-appb-000002
从而，处理节点3可以获取报文中携带的业务标识，例如，可以是承载于报文的目标MAC地址字段中的信息(例如，如上所述由处理节点1添加的0x000000000ABC)，并根据该业务标识基于表5查找到针对该报文的处理策略：通过转发端口20发送该报文，并删除业务标识，例如，将承载于报文的目标MAC地址字段中的信息替换为该报文进入承载网络之前的原始的目的MAC地址，即：0x112233445566。
这里，处理节点3删除业务标识的方式仅为实例性说明，可以根据添加该业务标识的方式(例如图3或图4所示方式)任意变更。
需要说明的是，以上列举说明的处理节点3删除业务标识的方式，但本发明并不限定于此，也可以由控制设备删除。
