    • A method and system are described for distributing at least one clock signal between shelves in a multi-shelf modular computing system includes a clock signal generator for generating a first clock signal, an inter-shelf bus for carrying the first clock signal to a second shelf, and a first shelf manager module, associated with the second shelf, for receiving and regenerating the first clock signal and providing the regenerated first clock signal to at least one module within the second shelf. A system and method for detecting a location of a fault in an inter-shelf bus in a multi-shelf modular computing system is also disclosed. A power source applies a bias between at least two conductors of the inter-shelf bus. At least one module detects the applied bias to determine if a fault is located between the at least one shelf and the power source.

    • A system and method for configuring a software defined radio is disclosed. In an embodiment, a smart card and smart card reader are used to access layered information pre-programmed into a software defined radio. The smartcard reader extracts configuration information from the smart card and the configuration information is used to configure the software defined radio. The configuration may include, communication protocols, modulation/demodulation techniques, digital processing protocols, coding/decoding techniques, security authorization; operational protocols, and other information. Individual users may be given different levels of access depending on, among other things, the user's service requirements, mission requirements, security clearance, and/or authorization level. The disclosed systems and methods significantly reduce the amount of time and training required for personnel to establish communications using a software defined radio.
    • 公开了一种用于配置软件定义的无线电的系统和方法。 在一个实施例中,智能卡和智能卡读取器用于访问预编程到软件定义的无线电中的分层信息。 智能卡读卡器从智能卡中提取配置信息,配置信息用于配置软件定义的无线电。 该配置可以包括通信协议,调制/解调技术,数字处理协议,编码/解码技术,安全授权; 操作协议和其他信息。 取决于用户的服务要求,任务要求,安全许可和/或授权级别,可以向个人用户提供不同的访问级别。 所公开的系统和方法显着地减少了人员使用软件定义的无线电建立通信所需的时间和训练量。

    • Methods and systems for distributing messages of a ring-topology-based link level communications protocol over a star-topology using a star-topology-based link level communications protocol are disclosed. According to one method, when a packet of the ring-topology-based link level communications protocol is received, it is determined whether the packet is to be sent to a number of destinations and returned to a sender. If the packet is intended for distribution to a number of destinations and return to the sender, the packet is encapsulated in a frame of the star-topology-based link level communications protocol, the destination address in the frame is set to a next destination address in a virtual ring topology, the frame is forwarded to a switch. The switch forwards the packet to the next destination in the virtual ring based on the input port and the destination address of the star-topology-based link level communications protocol. The process continues until the packet reaches the last destination in the virtual ring where the packet is encapsulated in a frame of the star-topology-based link level communications protocol and returned to the sender.
    • 公开了使用基于星形拓扑的链路级通信协议通过星形拓扑分发基于环形拓扑的链路级通信协议的消息的方法和系统。 根据一种方法,当接收到基于环形拓扑的链路级通信协议的分组时,确定分组是否被发送到多个目的地并且返回给发送者。 如果分组旨在分发到多个目的地并返回到发送者,则该分组被封装在基于星形拓扑的链路级通信协议的帧中,该帧中的目的地址被设置为下一个目的地址 在虚拟环形拓扑中,帧被转发到交换机。 交换机根据基于星形拓扑的链路层通信协议的输入端口和目的地址将数据包转发到虚拟环中的下一个目的地。 该过程一直持续到分组到达虚拟环中的最后一个目的地,其中分组被封装在基于星形拓扑的链路级通信协议的帧中并返回给发送者。
