    摘要： A network configuration device or entity has control of defined management and security functions in the network, or in many embodiments, in a Fiber Channel fabric. The network configuration device may control many functions. Foremost, it may control the recognition, operation and succession procedure for network configuration entities. It may also control user configurable options for the network, rules for interaction between other entities in the network, rules governing management-level access to the network, and rules governing management-level access to individual devices in the network. In addition, the network configuration entity may exploit policy sets to implement its control.

    摘要： A method and apparatus for securing networks, focusing on application in Fibre Channel networks. A combination of unique security techniques are combined to provide overall network security. Responsibility for security in the network is assigned to one or more designated entities. The designated entities deploy management information throughout the network to enhance security by modifying the capabilities and operational permissions of the devices participating in the network. For example, through network control: logical management access or physical I/O access may be limited on a per device or per I/O basis; and all devices and ports in the network operate only with other approved devices and ports. These designated entities can better manage network security by exploiting a unique link authentication system as well as a unique push-model secure distributed time service. The link authentication involves a multi-phase nonce exchange exploiting various derivations of the nonce and other information such as hashes and encryptions. The push-model secure time distribution departs from the traditional Fibre Channel pull mode time distribution and provides for secure and reliable distributed time so that various security attacks may be defeated.

    摘要： A heart valve prosthesis is provided having a self-expanding multi-level frame that supports a valve body comprising a skirt and plurality of coapting leaflets. The frame transitions between a contracted delivery configuration that enables percutaneous transluminal delivery, and an expanded deployed configuration having an asymmetric hourglass shape. The valve body skirt and leaflets are constructed so that the center of coaptation may be selected to reduce horizontal forces applied to the commissures of the valve, and to efficiently distribute and transmit forces along the leaflets and to the frame. Alternatively, the valve body may be used as a surgically implantable replacement valve prosthesis.

    摘要： One embodiment of the present invention provides a system that accommodates different clock frequencies in an Ethernet passive optical network (EPON). The system receives a signal from an optical line terminal (OLT) at an optical network unit (ONU) and derives an OLT clock. The system also maintains a local clock. The system further receives from the OLT an assignment for an upstream transmission window, during which the ONU can transmit an upstream data burst to the OLT based on the local clock. The system adjusts the number of bits of the data burst without affecting the payload data carried in the data burst, thereby allowing the data burst to fit properly within the upstream transmission window and compensating for frequency differences between the local clock and the OLT clock. The system transmits the data burst based on the local clock in the upstream transmission window.

    摘要翻译： 本发明的一个实施例提供一种在以太网无源光网络（EPON）中适应不同时钟频率的系统。 该系统从光网络单元（ONU）的光线路终端（OLT）接收信号，得到OLT时钟。 该系统还维护本地时钟。 该系统还从OLT接收用于上行传输窗口的分配，在该传输窗口期间，ONU可以基于本地时钟向OLT发送上行数据突发。 该系统调整数据脉冲串的位数，而不影响数据脉冲串中承载的有效载荷数据，从而允许数据脉冲串适配于上游传输窗口内，并补偿本地时钟与OLT时钟之间的频率差异。 系统根据上行传输窗口中的本地时钟传输数据脉冲串。
