    摘要： A method for filtering multicast sources, so that when the multicast routing protocol is based on the Source-Specific Multicast (SSM) model, resource consumption of inquiry routers can be reduced and the multicast packet forwarding efficiency can be improved. In the present invention, the inquiry router determines whether it is the Any-Source Multicast (ASM) model or the SSM model that the multicast routing protocol running in the network is based on. If it is the ASM model, maintain the source filtering method in the related art. If it is the SSM model, cancel the source filtering process or only performing the source filtering process in the inclusive mode. In the situation that only the source filtering process in the inclusive mode is performed, the additional filtering mode switching function or static configuration by software guarantees that the inquiry router is only in the inclusive mode, thereby avoiding the mode switching.

    摘要翻译： 一种过滤组播源的方法，当组播路由协议基于源特定组播（SSM）模型时，可以减少查询路由器的资源消耗，提高组播报文的转发效率。 在本发明中，查询路由器确定是否是在网络中运行的组播路由协议基于的任意源组播（ASM）模型或SSM模型。 如果是ASM模型，请在相关技术中维护源过滤方法。 如果是SSM模型，请取消源过滤处理或仅在包含模式下执行源过滤处理。 在仅执行包含模式的源过滤处理的情况下，通过软件的附加过滤模式切换功能或静态配置保证了查询路由器仅处于包容性模式，从而避免了模式切换。
