    • A multicast router having one or more downstream network interfaces situated in a data network system between sources that send multicast packets to at least one multicast group address and one or more hosts that request data from the multicast group address and the sources. The multicast router receives ASM (Any Source Multicast) traffic requests and SSM (Source Specific Multicast) traffic requests from the one or more hosts using a host- router multicast routing protocol and stores for a downstream network interface and multicast group address at least one INCLUDE source record containing a non-empty source list derived by the SSM and the ASM traffic requests made by the one or more hosts and/or at least one EXCLUDE source record containing a non-empty Requested source list derived by the SSM and the ASM traffic requests made by the one or more hosts. In an alternative implementation a multicast router is provided that has one or more downstream network interfaces and is situated in a data network system between sources that send multicast packets to at least one multicast group address and multiple hosts that request data from the multicast group address and the sources. The multicast router stores for a each downstream network interface, each multicast group address and each host at least one INCLUDE source record and at least one EXCLUDE source record which are derived from ASM and SSM traffic requests made by the hosts using a host-router multicast routing protocol.
    • 具有位于数据网络系统中的一个或多个下游网络接口的组播路由器,所述数据网络系统在将多播分组发送到至少一个多播组地址的源和从多播组地址和源请求数据的一个或多个主机之间。 多播路由器使用主机路由器组播路由协议接收来自一个或多个主机的ASM(任何源多播)流量请求和SSM(源特定多播)流量请求,并存储下游网络接口和多播组地址至少一个INCLUDE 源记录,其包含由SSM导出的非空源列表以及由一个或多个主机和/或至少一个包含由SSM和ASM流量导出的非空请求源列表的至少一个EXCLUDE源记录所做的ASM流请求 一个或多个主机发出的请求。 在替代实现中,提供了具有一个或多个下游网络接口并且位于数据网络系统中的数据路由器,所述数据网络系统在向多个组地址发送多播分组的源和从多播组地址请求数据的多个主机之间,以及 来源。 组播路由器存储每个下游网络接口,每个组播组地址和每个主机至少一个INCLUDE源记录和至少一个EXCUDE源记录,这些记录是从主机使用主机路由器多播从ASM和SSM流量请求中产生的 路由协议

    • The invention relates to a security sensor (10) comprising a sensing device (21), a coming optical fiber element and a going optical fiber element, the sensing device (21) comprising a housing that receives a first end of the coming element and a first end of the going element. It is characterized in that the first end of the coming element and the first end of the going element in the housing are not aligned, and in that when a light beam enters the housing through the first end of the coming element, at least part of said light beam is reflected within the housing and exits through the first end of the going element.
    • 本发明涉及一种安全传感器(10),包括感测装置(21),即将来来的光纤元件和走向光纤元件,该感测装置(21)包括容纳即将到来的元件的第一端和 元素的第一个结束。 其特征在于,未来元件的第一端和壳体中的元件的第一端不对准,并且当光束通过未来元件的第一端进入壳体时,至少部分 所述光束在壳体内被反射并且通过去除元件的第一端而离开。
