Description

报文转发方法及装置、存储介质、电子装置
交叉引用
本发明要求在2018年12月14日提交中国专利局、申请号为201811534502.7、发明名称为“报文转发方法及装置、存储介质、电子装置”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本发明涉及通信领域，具体而言，涉及一种报文转发方法及装置、存储介质、电子装置。
背景技术
随着通信技术的发展，为了满足拓扑网络之间高宽带、高稳定性以及冗余备份的高可靠性要求，链路聚合(SmartGroup)功能被广泛用于虚拟交换集群环境。
虚拟交换集群(Vritual Switch Cluster，简称为VSC)作为一种网络虚拟化技术，可以将多个单独运行的物理设备组成一个虚拟设备，彼此之间通过拓扑发现协议发现对方，并通过一台主设备来管理整个VSC***，其他设备作为备份设备担任转发角色。在VSC***中，为了保障某一成员设备出现意外故障后***运行及流量转发不受影响，一个链路聚合SmartGroup组中的成员端口往往分布于各个成员设备用于流量的及时切换和转发。
SmartGroup作为流量出端口时，报文会通过哈希算法选择聚合组中一个成员端口进行转发。为了便于对流量的监控和分析，往往希望从本设备进入的流量选择最短路径，优先从聚合组中本设备的成员端口进行转发。对于已知单播报文，由于与其转发相关的SmartGroup寄存器TRUNK_GROUP、TRUNK_MEMBER中表项PORT_NUM、MODULE_ID可以区分成员端口是否为本设备端口。因此通过对相关寄存器表项的设置可以实现已知单播报文在VSC***中本地优先转发的功能。
然而，对于VSC***中出端口为SmartGroup的非已知单播报文，是不支持本地优先转发的。这是由于非已知单播具有泛洪的特性以及相关SmartGroup寄存器表项NONUCAST_TRUNK_BLOCK_MASK中表项BLOCK_MASK是以VSC***聚合组中的所有成员端口掩码的方式进行设置的，进入设备的报文哈希到索引值后从所有成员端口中选择一个端口进行转发，未能实现本地优先转发。
针对相关技术中，设备接收到非已知单播报文后，无法实现本地优先转发等问题，尚未提出有效的技术方案。
发明内容
本发明实施例提供了一种报文转发方法及装置、存储介质、电子装置，以至少解决相关技术中设备接收到非已知单播报文后，无法实现本地优先转发等问题。
根据本发明的一个实施例，还提供了一种报文转发方法，包括：按照以下方式设置第一设备上的寄存器表项：仅将所述第一设备的聚合组的成员端口和所述成员端口的个数作为所述寄存器表项；按照设置的所述寄存器表项转发所述第一设备接收的非已知单播报文。

附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：

图2为根据本发明实施例的报文转发方法的流程图；
图3为根据本发明实施例的VSC***非已知单播本地优先转发示意图；

图6为根据本发明优选实施例的VSC***非已知单播本地优先转发流程图。
具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
现有的VSC***中，当非已知单播报文(以下简称为流量)从本设备进入泛洪到SmartGroup时，如果本设备有该聚合组的成员端口，流量会选择从本设备端口进行转发，如果本设备没有该聚合组中的成员端口流量则选择其他设备的成员端口进行转发。
现阶段VSC***非已知单播报文的转发机理如下：如图1所示，以Switch A和Switch B构建VSC***为例，A设备1端口、2端口与B设备3端口、4端口组成同一Smart Group1，此时A、B设备上寄存器NONUCAST_TRUNK_BLOCK_MASK中表项BLOCK_MASK设置如下所示。
Figure PCTCN2019114787-appb-000001
基于上述表项设置，以进入A设备的非已知单播流量为例进行分析，首先根据报文内容哈希出一索引(以1为例)，根据这一索引查找A、B设备寄存器表项BLOCK_MASK(此时A设备表项为ipipe0[1]:<BLOCK_MASK＝0x0006>；B设备表项为ipipe0[1]:<BLOCK_MASK＝0x0008>)，A设备中成员口1端口、2端口和B设备成员口4端口被掩掉，则流量会选择从B设备3端口进行转发。由于非已知单播流量转发相关SmartGroup寄存器表项下发的为VSC***聚合组中的所有成员端口个数，致使非已知单播报文未能实现本地优先转发。
为了能够实现VSC***中非已知单播报文本地优先转发的功能，本发明以下实施例提供了NONUCAST_TRUNK_BLOCK_MASK寄存器设置的新方法。
实施例1
本发明实施例提供了一种报文转发方法，图2为根据本发明实施例的报文转发方法的流程图，如图2所示，包括：步骤S202，按照以下方式设置第 一设备上的寄存器表项：仅将所述第一设备的聚合组的成员端口和所述成员端口的个数作为所述寄存器表项；步骤S204，按照设置的所述寄存器表项转发所述第一设备接收的非已知单播报文。
通过上述步骤，通过先按照以下方式设置第一设备上的寄存器表项：仅将所述第一设备的聚合组的成员端口和所述成员端口的个数作为所述寄存器表项，然后按照设置的寄存器表项转发所述第一设备接收的非已知单播报文，采用上述技术方案，解决了相关技术中，设备接收到非已知单播报文后，无法实现本地优先转发等问题，进而可以优先转发非已知单播报文。
在实际应用中，为了避免第一设备接收到的非已知单播报文泛洪到其他设备，本发明实施例中，还提供了以下技术方案：按照设置的所述寄存器表项转发所述第一设备接收的非已知单播报文之前，所述方法还包括：判断其他设备是否存在所述聚合组的成员端口，其中，所述第一设备和其他设备位于同一虚拟集***换VSC***中；在判定所述其他设备存在所述聚合组的成员端口后，在所述第一设备上开启跨设备的流量隔离功能，以防所述非已知单播报文从所述其他设备的成员端口转发，在判定所述其他设备不存在所述聚合组的成员端口时，对其他设备可不作处理。
在本发明实施例中，至少按照以下方式设置第一设备上的寄存器表项：仅将所述第一设备的聚合组的成员端口和所述成员端口的个数作为所述寄存器表项之前，所述方法还包括：获取所述聚合组在所述第一设备上的分布情况，所述分布情况包括：所述第一设备上的所述聚合组的成员端口和所述成员端口的个数。
在本发明实施例中，所述其他设备的个数为至少一个，即在上述VSC***中，可以包括多个设备。
在本发明实施例中,按照设置的所述寄存器表项转发所述第一设备接收的非已知单播报文，包括：从设置的所述寄存器表项中选择成员端口；基于所述成员端口转发所述非已知单播报文。
在本发明实施例中，按照以下方式设置第一设备上的寄存器表项：仅将所述第一设备的聚合组的成员端口和所述成员端口的个数作为所述寄存器表项之前，所述方法还包括：判断所述第一设备上是否存在所述所述第一设备的聚合组的成员端口，其中，在判断结果为是时，按照以下方式设置第一设备上的寄存器表项：仅将所述第一设备的聚合组的成员端口和所述成员端口的个数作为所述寄存器表项。
以下示例以VSC***中存在两个设备：A设备(Switch A)和B设备(Switch B)为例进行说明。
如图3所示，其中，Switch A和Switch B构建VSC***，A设备1端口、2端口与B设备3端口、4端口组成同一SmartGroup1，具体实现的方法如下：若A设备有SmartGroup1中成员端口时，则只下发A设备成员端口和个数设置寄存器NONUCAST_TRUNK_BLOCK_MASK中表项BLOCK_MASK，A设备寄存器设置如下所示。
Figure PCTCN2019114787-appb-000002
在寄存器采用上述方式设置后，此时可以确保A设备进入的流量可以从聚合组中成员端口1口或2口进行转发，同时若B设备也有SmartGroup1中成员端口，则开启跨设备流量目的端口隔离功能，当流量通过Hig端口泛洪到B设备目的端口SmartGroup1时，将聚合组中成员端口(3、4端口)隔离掉，防止形成泛洪流量转发翻倍的问题，当然，若A设备没有SmartGroup1中成员端口时，则按照现有转发模式进行处理。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
实施例2
在本实施例中还提供了一种报文转发装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图4是根据本发明实施例的报文转发装置的结构框图，如图4所示，该装置包括：设置模块40，用于按照以下方式设置第一设备上的寄存器表项：仅将所述第一设备的聚合组的成员端口和所述成员端口的个数作为所述寄存器表项；转发模块42，用于按照设置的所述寄存器表项转发所述第一设备接收的非已知单播报文。
通过本发明的技术方案，通过先按照以下方式设置第一设备上的寄存器表项：仅将所述第一设备的聚合组的成员端口和所述成员端口的个数作为所述寄存器表项，然后按照设置的寄存器表项转发所述第一设备接收的非已知单播报文，采用上述技术方案，解决了相关技术中，设备接收到非已知单播报文后，无法实现本地优先转发等问题，进而可以优先转发非已知单播报文。
如图5所示，在本发明实施例中，所述装置还包括：判断模块44，用于判断其他设备是否存在所述聚合组的成员端口，其中，所述第一设备和其他设备位于同一虚拟集***换VSC***中；开启模块46，用于在判定所述其 他设备存在所述聚合组的成员端口后，在所述第一设备上开启跨设备的流量隔离功能，以防所述非已知单播报文从所述其他设备的成员端口转发。
在本发明实施例中，如图5所示，所述装置还包括：获取模块48，用于获取所述聚合组在所述第一设备上的分布情况，所述分布情况包括：所述第一设备上的所述聚合组的成员端口和所述成员端口的个数。
需要说明的是，上述VSC***中的其他设备的个数为至少一个。

步骤S508，若SmartGroup1中有成员端口位于A设备，下发本地成员端口和个数设置寄存器NONUCAST_TRUNK_BLOCK_MASK中表项BLOCK_MASK。
步骤S508，判断B设备是否有SmartGroup1中成员端口，若没有则不作处理。
步骤S510，若SmartGroup1中有成员端口位于B设备，则对A设备本地成员端口进行隔离，防止从A设备与含有成员端口的B设备连接的Hig端口流入的泛洪流量从A设备成员端口转发。
步骤S512，若SmartGroup1中没有成员端口位于B设备，则按照原流程进行处理。
