摘要： A telecommunications device (10) and method of executing a telecommunications device function using data stored in a radio frequency identification (RFID) tag (14) are presented. The telecommunications device (10) is positioned near the RFID tag (14) and a device function is selected. An interrogation signal is transmitted from the telecommunications device (10) to the RFID tag (14). In response, the RFID tag (14) broadcasts stored data. The device function is executed using at least a portion of the broadcast data. The device function can be, for example, the initiation of a communications session with another telecommunications device. In another example, the device function includes storing at least a portion of the broadcast data in a memory module and associating the stored broadcast data with a user reference for later retrieval.

摘要： Multicast capabilities of a link state protocol controlled network are used to accelerate the flooding advertisement of topology change notifications within portions of the network. This flooding mechanism may be particularly efficient in a network with a large number of two-connected nodes such as a ring network architecture. A control plane specific multicast group address is used when flooding topology change notifications, and a process such as reverse path forwarding check is used as an additional control on forwarding of the notification to prevent looping of control plane packets. Two-connected nodes insert a forwarding entry into their FIB to enable frames containing the control message to be forwarded via the data plane on to the downstream node so that propagation of the control message along a chain of two-connected nodes may occur at data plane speeds.
摘要翻译：链路状态协议控制网络的组播功能用于加速网络部分内的拓扑变化通知的泛洪广告。这种洪泛机制在具有大量双连接节点（例如环网架构）的网络中可能是特别有效的。泛洪拓扑变化通知时使用控制平面特定的组播组地址，并且使用诸如反向路径转发检查之类的过程作为通知转发的附加控制，以防止控制平面分组的循环。双连接节点将转发条目插入到其FIB中，以使包含控制消息的帧能够经由数据平面转发到下游节点，使得控制消息沿双连接节点链的传播可能发生在数据平面速度。
