    • A peer-to-peer communication system that transmits application data from an application component on one network peer to an application component on another network peer. A programming interface is provided to the communication system to facilitate programming of applications that rely on peer-to-peer communications. The communication system uses messaging providers to which each peer may be connected for purposes other than communications between peer-to-peer application components, thereby reducing the resources a peer-to-peer application requires for communication and making the system advantageous for use in portable electronic devices. Additionally, the communication system uses addresses already assigned in each messaging provider, allowing peer-to-peer communication between peers that may otherwise have been non-addressable.
    • 一种对等通信系统,将应用数据从一个网络对等体上的应用组件传输到另一个网络对等体上的应用组件。 向通信系统提供编程接口,以方便对依赖于对等通信的应用进行编程。 通信系统使用每个对等体可以连接的消息传递提供者,用于对等应用组件之间的通信以外的目的,从而减少对等应用对于通信所需的资源,并使系统有利于在便携式 电子设备。 另外,通信系统使用已经在每个消息传递提供者中分配的地址,允许对等体之间的对等通信,否则可能是不可寻址的。

    • Relatively-temporary applications may be installed. As a result of the installation and/or execution of such an application, an associated application isolated storage unit may be established. When established, the application isolated storage unit is designated for private storage use by the associated application. Additionally, a linkage between the application isolated storage unit and the associated application is created. Upon initiation of a reclamation procedure, the linkage from the application isolated storage unit is traced to the indicated location of the associated application. If the associated application no longer exists, the application isolated storage unit is deleted so as to reclaim the memory space.
    • 可以安装相对临时的应用程序。 作为这样的应用的安装和/或执行的结果,可以建立相关联的应用隔离存储单元。 建立后,应用程序隔离存储单元被指定用于相关应用程序的私人存储使用。 另外,创建应用程序隔离存储单元和相关应用程序之间的链接。 在开始回收程序时,来自应用程序隔离存储单元的链接被追溯到相关应用的指示位置。 如果相关联的应用程序不再存在,则删除应用程序隔离存储单元以回收内存空间。

    • Methods and apparatus for switching Fibre Channel Arbitrated Loop Systems is provided between a plurality of Fibre Channel Loop devices. In one aspect of the invention, the system switches based at least in part on arbitrated loop primitives. An exemplary interconnect system may include a first port and a second port, both including port logic to monitor certain arbitrated loop primitives, a connectivity apparatus, a route determination apparatus including a routing table consisting of ALPA addresses and their associated ports, the route determination apparatus coupled to each port and the connectivity apparatus, where the connectivity apparatus creates paths between the ports based on arbitrated loop primitives. In one embodiment, the connectivity apparatus is a crossbar switch. Examples of the arbitrated loop primitives that cause the switch to create paths between ports includes one or more of the following: ARB, OPN and CLS. In yet other aspects, the system ensures device access fairness through one or more techniques, including a rotating priority system, a counter to count the number of OPNs, especially sequential OPNs, and/or priority based on port type. Device zoning may be implemented. In one implementation, the system includes trunking such that frames may be transferred on multiple ports.
    • 在多个光纤通道环路设备之间提供用于交换光纤通道仲裁环路系统的方法和设备。 在本发明的一个方面,系统至少部分地基于仲裁的循环原语来切换。 示例性互连系统可以包括第一端口和第二端口,两者都包括用于监视某些仲裁环路原语的端口逻辑,连接装置,包括由ALPA地址及其相关联的端口组成的路由表的路由确定装置,路由确定装置 耦合到每个端口和连接装置,其中连接装置基于仲裁的循环基元在端口之间创建路径。 在一个实施例中,连接装置是交叉开关。 导致交换机在端口之间创建路径的仲裁循环图元的示例包括以下一个或多个:ARB,OPN和CLS。 在另一方面,该系统通过一种或多种技术来确保设备访问的公平性,包括旋转优先级系统,计数OPN数量的计数器,特别是连续的OPN,和/或基于端口类型的优先级。 可以实现设备分区。 在一个实现中,系统包括中继,使得帧可以在多个端口上传送。
