摘要： Embodiments that facilitate the fair and dynamic distribution of central processing unit (CPU) time are disclosed. In accordance with one embodiment, a method includes organizing one or more processes into one or more groups. The method further includes allocating a CPU time interval for each group. The allocation of a CPU time interval for each group is accomplished by equally distributing a CPU cycle based on the number of groups. The method also includes adjusting the allocated CPU time intervals based on a change in the quantity of the one or more groups.

摘要： Techniques are disclosed for virtualizing internet protocol (IP) addresses in terminal server sessions. A client component comprises a layer service provider (LSP) and a name service provider (NSP) that intercept a socket call to associate a port with a socket for a terminal server session. The client component queries a server component for a virtual IP address, and the server component determines whether the terminal server session can use a virtual IP address. Where the session can use a virtual IP address, the server returns a virtual IP address and the client component binds the socket call to the virtual IP address. Where the session cannot use a virtual IP address, the server returns an indication of that, and the client component acts as a proxy for that socket call and any future calls for that socket.
摘要翻译：公开了用于虚拟化终端服务器会话中的因特网协议（IP）地址的技术。客户端组件包括层服务提供商（LSP）和名称服务提供商（NSP），其拦截套接字调用以将端口与终端服务器会话的套接字相关联。客户端组件查询服务器组件的虚拟IP地址，服务器组件确定终端服务器会话是否可以使用虚拟IP地址。会话可以使用虚拟IP地址的位置，服务器返回虚拟IP地址，客户端组件将套接字调用绑定到虚拟IP地址。在会话无法使用虚拟IP地址的情况下，服务器返回该指示，并且客户端组件充当该套接字调用的代理，以及将来对该套接字的调用。

摘要： Embodiments that facilitate the fair and dynamic distribution of disk input/output (IO) bandwidth are disclosed. In accordance with one embodiment, the method includes organizing one or more disk IO time intervals into one or more queues. The method further includes allocating a disk IO time interval to each queue. The allocation of a disk IO time interval to each queue is accomplished by equally distributing a disk IO cycle based on the number of queues. The one or more disk IO requests are then processed during the corresponding disk IO time interval.

摘要： A method to offload a network stack connection is presented. A request, which includes a list of resource requirements from each software layer in the stack, to offload the network stack connection is sent through the stack to the peripheral device. The device allocates resources for the list and sends a handle to each of the software layers for communication with the device. The state for each layer is sent to the device that includes state variables that are classified as a constant, a cached variable handled by the CPU, or a delegated variable handled by the device.

摘要： A mapping between virtual processing units and physical processing units allows for an increase or decrease in the number of physical processing units installed in a computing device without disrupting the computing device's network communications. At startup, each of the virtual processing units can be allocated the necessary network communication management structures for supporting network communication. The networking subsystem can continue to use the virtual processing units as it would physical processing units, namely packets can be routed through the appropriate processing unit. However, because the networking subsystem is only aware of the virtual processing units, the mapping between the virtual processing units and the physical processing units can continually adjust for changes in the number of physical processing units installed, allowing the number of installed physical processing units to be modified without affecting the operation of the networking subsystem or ongoing network communications.
摘要翻译：虚拟处理单元和物理处理单元之间的映射允许安装在计算设备中的物理处理单元的数量的增加或减少，而不会中断计算设备的网络通信。在启动时，每个虚拟处理单元可以被分配用于支持网络通信的必要的网络通信管理结构。网络子系统可以继续使用虚拟处理单元，如物理处理单元，即数据包可以通过适当的处理单元进行路由。然而，由于网络子系统仅仅知道虚拟处理单元，所以虚拟处理单元和物理处理单元之间的映射可以连续地调整所安装的物理处理单元的数量的变化，从而允许安装的物理处理单元的数量被修改而不影响网络子系统的运行或正在进行的网络通信。
