摘要： Resource requests from a plurality of schedulable entities are scheduled while limiting the maximum and minimum quality of service allocated to each schedulable entity. The resource scheduler of the present invention requires less memory maintain state information than existing rate-controlling schedulers, and is thus more easily scalable to large numbers of users. The resource scheduler also schedules resources fairly among competing schedulable entities. A fair-share scheduling algorithm is used by a resource scheduler to select resource requests to service. A rate controller checks to ensure that servicing the selected request will not cause the associated user's maximum quality of service to be exceeded. If the maximum quality of service will not be exceeded, the virtual time used in the scheduling algorithm is incremented, and the request is serviced. If the maximum quality of service will be exceeded, the virtual time is still incremented, but the request is not serviced and remains pending.
摘要翻译：调度来自多个可调度实体的资源请求，同时限制分配给每个可调度实体的最大和最小服务质量。本发明的资源调度器比现有的速率控制调度器需要更少的存储器维护状态信息，因此更容易地扩展到大量的用户。资源调度器还可以在竞争的可调度实体之间公平地调度资源。资源调度程序使用公平共享调度算法来选择资源请求进行服务。速率控制器检查以确保为所选择的请求提供服务不会导致超出相关用户的最大服务质量。如果不超过最大服务质量，则调度算法中使用的虚拟时间增加，并且请求得到服务。如果最大服务质量将被超过，则虚拟时间仍然增加，但请求未被维护并保持挂起。

摘要： Communications between network devices on a logical subnet are restricted between devices authorized to communicate with each other, even though other network devices may be present on the subnet. When a network device receives a request to provide it L2 address to a requesting network device, it responds with its L2 address only if the requesting device is authorized to request L2 address. Optionally, a network device only transmits requests for the L2 addresses of other devices if it authorized to do so. The information describing authorized devices maybe store as list of L2 and L3 addresses, which list may be loaded by each network device when starting up. Preferably, authorized devices include routers on the device's logical subnet, to allow the routers to communicate with, and route packets to, the network devices.

摘要： An I/O multiplexing operation involving a cross-domain file descriptor set is intercepted. The cross-domain set is divided into a first subset corresponding to a first file type and a second subset corresponding to a second file type. System calls are initiated in parallel for performing separate I/O multiplexing operations on the first and second subsets of file descriptors. In response to one of the parallel system calls identifying at least one file descriptor ready for communication, the other parallel system call is unblocked. Sets of file descriptors identified as ready for communication by the parallel system calls are combined and returned to a calling process.

摘要： Apparatus and method of cluster computing are described. The present invention provides a useful compromise between the manageability, power, and ease of use of centralized systems and the reliability, fault-tolerance, upgradability, and scalability of distributed systems. Moreover, the present invention provides fault-tolerance and security while adhering to real-time to respond constraints or bounds. The invention is described in preferred embodiment examples in the context of two clustered applications: a telecommunication switch-controller and a Web servers, although many practical applications will benefit from the present invention.

摘要： A method and system for handling incoming calls when no destination stations are available. When an incoming call from an originating station is received, it is determined whether a destination station is available. If a destination station is not available, a telephone number of the originating station is stored, Shortly before its current call is concluded, a destination station indicates its approaching availability. Responsive to this indication, an outgoing call is placed to the originating station. If the originating station does not answer the outgoing call within a predetermined time, the outgoing call is terminated and rescheduled. If the originating station answers the call within a predetermined time, the outgoing call is connected to the available destination station.

摘要： Methods are provided for achieving consensus among an order in which write requests are received by various ones of a plurality of nodes in a distributed system using a shared data structure. The plurality of nodes are organized into groups of nodes and successively larger groupings of groups, based on physical proximity. A consensus protocol is used to achieve consensus among groups of nodes, and then among the groupings of groups of nodes in a logical tree structure up to a root level virtual node. Recovery from failure of all nodes in a group is supported.

摘要： The short-range wireless communication on a mobile communication device is optimized to balance between preserving battery power and processing urgent data without delay. A wireless access schedule identifying time periods during which the mobile communication device is assumed to have access to short-range wireless communication is created or provided. Data to be transmitted or received by the mobile communication device is classified as being urgent or non-urgent. When data is to be transmitted or received by the mobile communication device, the transmission or receipt of the data is managed according to 1) whether or not the data is urgent, and 2) whether the current time is within a time period during which the mobile communication device is assumed to have access to short-range wireless communication.

摘要： A system and a method dynamically adjusts the quality of service guarantees for virtual servers based upon the resource demands experienced by the virtual servers. Virtual server resource denials are monitored to determine if a virtual server is overloaded based upon the resource denials. Virtual server resources are modified dynamically to respond to the changing resource requirements of each virtual server. Occasionally, a physical host housing a virtual server may not have additional resources to allocate to a virtual server requiring increased resources. In this instance, a virtual server hosted by the overloaded physical host is transferred to another physical host with sufficient resources.

摘要： Super-user privileges are virtualized by designating a virtual super-user for each of a plurality of virtual processes and intercepting system calls for which actual super-user privileges are required, which are nevertheless desirable for a virtual super-user to perform in the context of his or her own virtual process. In one embodiment, a computer operating system includes multiple virtual processes, such as virtual private servers. Each virtual process can be associated with one or more virtual super-users. When an actual process makes a system call that requires actual super-user privileges, the call is intercepted by a system call wrapper.
摘要翻译：超级用户权限通过为多个虚拟进程中的每一个指定虚拟超级用户而进行虚拟化，并且拦截系统呼叫，对于哪个实际的超级用户特权是必需的，这对于虚拟超级用户在上下文中执行是合乎需要的他或她自己的虚拟过程。在一个实施例中，计算机操作系统包括多个虚拟进程，诸如虚拟专用服务器。每个虚拟进程可以与一个或多个虚拟超级用户相关联。当实际进程进行需要实际超级用户权限的系统调用时，该调用将被系统调用包装器拦截。
