摘要： A computer operating system that allows legacy applications to be run automatically with quality of service (QoS) guarantees matching required QoS performance levels. In accordance with the invention, files have QoS requirement attributes that can be set-by users. Additionally, users may interpose a requirement broker between a given legacy application and the operating system. The requirement broker may be in the form of a modified version of a library that is dynamically linked with applications at load time. The requirement broker intercepts certain system calls and automatically requests from the system QoS guarantees in accordance with the QoS requirement attributes of the accessed files, whether local or remote.

摘要： A uniform application programming interface (API) provides efficient generation and control of resource reservations so as to ensure a desired quality of service (QoS) for applications running on an operating system of a computer system. The uniform API is based on a hierarchical file system which associates resource reservations with references to shared objects, rather than with the objects themselves. The uniform API permits the use of a variety of different proportional share schedulers for controlling access to physical resources, e.g., CPU, memory, disk, network interfaces, etc. of the computer system. The hierarchical file system includes a separate directory for each independently-scheduled physical resource of the computer system. A parent of the resource reservation in the hierarchical file system is either a root node of the file system or another reservation for the same resource. The resource reservation represents either an internal reservation, corresponding to a directory in the file system which is permitted to have child nodes associated therewith in the file system, or a queue, corresponding to a directory which is not permitted to have child nodes associated therewith. A given request for a resource reservation is processed by a proportional share scheduler associated with the resource, and identifies a queue having a predetermined portion of the resource allocated thereto. The invention also provides mechanisms for request tagging by the operating system, parental limitation of resources used by a child process, and “garbage collection” of resource reservations that are no longer needed.
摘要翻译：统一的应用编程接口（API）提供资源预留的有效生成和控制，以便确保在计算机系统的操作系统上运行的应用的期望的服务质量（QoS）。统一API基于分层文件系统，其将资源预留与对共享对象的引用相关联，而不是与对象本身相关联。统一API允许使用各种不同的比例共享调度器来控制对物理资源的访问，例如计算机系统的CPU，存储器，盘，网络接口等。分层文件系统包括用于计算机系统的每个独立调度的物理资源的单独的目录。分层文件系统中的资源预留的父节点是文件系统的根节点或相同资源的另一个预留。资源预留表示与文件系统中允许具有与文件系统相关联的子节点的目录相对应的内部预留，或对应于不允许具有与其相关联的子节点的目录的队列。资源预留的给定请求由与资源相关联的比例共享调度器处理，并且识别具有分配给其的资源的预定部分的队列。本发明还提供了由操作系统请求标记的机制，子进程使用的资源的父母限制以及不再需要的资源预留的“垃圾收集”。

摘要： A method and system for servicing disk I/O requests from domains which have been guaranteed minimum quality of disk service maintains I/O requests for each domain are in separate queues. The queues are serviced by a disk scheduler which selects requests from the queues in accordance with a fair queuing scheduling algorithm that considers the estimated time required to service the request at the head of a queue with regard for the size of the input or output associated with the request, the proportion of disk bandwidth assigned to the particular domain, and the state of the other queues.

摘要： A new scheduling method and policy for shared (server) resources, such as the CPU or disk memory of a multiprogrammed data processor. The scheduling is referred to as Move-To-Rear List Scheduling and it provides a cumulative service guarantee and well as more traditional guarantees such as fairness (proportional sharing) and bounded delay. In typical operation, a list is maintained for a server of processes seeking service from the server. Processes are admitted to the list only when maximum capacity constraints are not violated, and once on the list, are served in a front-to-back order. After receiving service, or upon the occurrence of other events, the position of the process on the list may be changed.

摘要： Received packets are processed utilizing protocol processing stages in an operating system, in accordance with a technique referred to as signaled receiver processing (SRP). A given protocol processing stage uses a next stage submit (NSS) function to pass a packet to a subsequent protocol processing stage. Each protocol processing stage is associated with one or more sockets. Each socket is associated with the input function of a protocol processing stage, an unprocessed input queue (UIQ) that contains packets destined to the socket but not yet processed by the socket's input function, and a list of owner processes, which expect input from the socket. NSS uses a multi-stage early demultiplexing (MED) function, which determines a packet's next destination socket, based on the stage currently processing the packet and on information contained in the packet. If the amount of buffering used by a packet plus the amount of input buffering already used by the packet's destination socket exceeds a designated limit associated with that socket, NSS drops the packet. Otherwise, NSS enqueues the packet in that socket's UIQ and signals that socket's owner processes. The signal triggers a default action corresponding to performance of the required protocol processing by one of the destination socket's owner processes, but those processes may override the default action by, e.g., deferring the required protocol processing until execution of a subsequent receive call.
摘要翻译：根据称为信令接收机处理（SRP）的技术，在操作系统中利用协议处理级来处理接收的分组。给定的协议处理阶段使用下一阶段提交（NSS）功能将数据包传递到后续的协议处理阶段。每个协议处理阶段与一个或多个套接字相关联。每个套接字与协议处理阶段的输入功能相关联，一个未处理的输入队列（UIQ），其包含目的地为套接字但尚未由套接字输入函数处理的数据包，以及所有者进程列表，插座。 NSS使用多阶段早期解复用（MED）功能，其基于当前处理分组的阶段和包中包含的信息来确定分组的下一个目的地套接字。如果数据包使用的缓冲量加上数据包目的套接口已经使用的输入缓冲量超过与该套接字相关联的指定限制，NSS将丢弃数据包。否则，NSS将该套接字的UIQ中的数据包排入队列，并指示套接字的所有者进程。信号触发与目标套接字所有者进程之一所需的协议处理性能相对应的默认动作，但是这些进程可以通过例如延迟所需的协议处理来覆盖默认动作，直到执行后续的接收呼叫。

摘要： A computer operating system in which transfer of control of executing threads between protection domains is implemented using specific portals dedicated to the particular transfer of control between two protection domains. The transfer of control may also include parameter manipulation. A server registers a portal specification with a portal manager, the portal specification defining the behavior of portals which transfer control to the server. Thereafter, when a client application desires service from the server, the client application requests instantiation of a portal which will transfer control of an execution thread from the client application protection domain to the server protection domain. Upon receipt of the request, the portal manager dynamically generates portal code and updates a portal table associated with the client application, thus instantiating the portal. When the client application desires to invoke the server, the client application issues a system call instruction which results in switching the processor to privileged mode, followed by a lookup to the portal table and a transfer of control to the portal code identified in the portal table. The execution of the portal code results in transfer of control of the execution thread to the protection domain of the server. Various parameter manipulation techniques are disclosed for improving the efficiency of the transfer of control.

摘要： A data replication system is disclosed in which replication functionalities between a host computer, an interconnecting computer network, and a plurality of storage devices are separated into host elements and a plurality of storage elements. The host computer is connected to one or more host elements. The host element is responsible for replicating data between the storage devices, which are each connected to an associated storage element, and for maintaining data consistency. Further, the host element instructs a storage element whose associated storage device does not contain up-to-date data to recover from another one of the plurality of storage elements and its associated storage device. The storage elements and their associated storage devices may be located in any combination of diverse or same geographical sites in a manner to ensure sufficient replication in the event of a site or equipment failure. The storage elements are responsible for executing read and write requests received from the host computer and for maintaining data consistency. When a storage element and its associated storage device is determined not to contain up-to-date data, recovery is effected by data transfer from one of the other storage elements and its associated storage device, that is indicated by the host element. Such recovery is done directly between the respective storage elements and associated storage devices, without transiting the data through the host element.
