    摘要: Large numbers of commodity servers in a data center may be inexpensively interconnected using low-cost commodity network switches, a first network port on each commodity server, a second network port on each commodity server, and a traffic-aware routing module executed on each commodity server. Connecting two or more commodity servers via the first network ports on each server to a commodity network switch forms a unit. Connecting two commodity servers in different units forms a group. Each unit has a direct connection via a second network port on a commodity server in the unit to another unit. Each group may have a direct connection via a second network port on a commodity server in the group to another group. Traffic-aware routing modules executed on each commodity server determine routing of data between servers and balance traffic across the first and second ports.

    摘要: A number of data center units in a data center system may be directly connected with each other via switch interfaces. The data center system is server-centric and scalable by storing routing logics (e.g., inter-data center unit logic and/or inner-data center unit logic) at each server to achieve routing, load balancing, and/or fault tolerance. Switch interfaces of the data center units, thus, may be dumb devices and a centralized router for routing data among data center units may be omitted.

    摘要: A geographic location of a network device is determined using response delay times from internet servers used as landmarks. A coordination server provides to a client a list of area landmark servers (ALS) with known geographic locations. The client probes ALSs, measures response delays, and provides results to the coordination server. The coordination server then provides to the client a list of additional city landmark servers (CLS) within the area. The client probes the CLSs and provides results to the coordination server which then determines the geographic location of the client.

    摘要: An apparatus comprises an implantable cardiac signal sensing circuit configured to provide a sensed depolarization signal from a ventricle and a processor. The processor includes a signal analyzer module and a tachyarrhythmia discrimination module. The signal analyzer module is configured to determine a measure of stability of ventricular (V-V) depolarization intervals using the depolarization signal, and determine a rate of change of the measure of stability. The tachyarrhythmia discrimination module is configured to detect an episode of tachyarrhythmia using the depolarization signal, determine whether the detected tachyarrhythmia is indicative of atrial tachyarrhythmia using the determined rate of change, and provide the determination to a user or process.
