摘要： A process is presented for supporting simultaneous disk read and write requests in a video server environment. Read requests are the result of movie viewing, while write requests are the result of video clip editing or movie authoring procedures. Due to real-time demands of movie viewing, read requests have to be fulfilled within certain deadlines, otherwise they are considered lost. Since the data to be written into disk is stored in main memory buffers, write requests can be postponed until critical read requests are processed. However, write requests still have to be proceeded within reasonable delays and without the possibility of indefinite postponement. This is due to the physical constraint of the limited size of the main memory write buffers. The new process schedules both read and write requests appropriately, to minimize the amount of disk reads that do not meet their presentation deadlines, and to avoid indefinite postponement and large buffer sizes in the case of disk writes.
摘要翻译：提出了一种在视频服务器环境中支持同时进行磁盘读写请求的过程。读取请求是电影观看的结果，而写入请求是视频剪辑编辑或电影创作过程的结果。由于电影观看的实时需求，读取请求必须在一定的期限内完成，否则被认为是丢失的。由于要写入磁盘的数据存储在主存储器缓冲区中，所以可以推迟写入请求，直到处理关键的读取请求为止。但是，写入请求仍然需要在合理的延迟之内进行，并且不会无限期地推迟。这是由于主存储器写入缓冲器的有限大小的物理约束。新进程适当地调度读取和写入请求，以最大程度地减少不符合其演示截止时间的磁盘读取量，并避免在磁盘写入情况下无限期推迟和大型缓冲区大小。

摘要： A data organization scheme for movies stored on a video server. The method utilizes the available bandwidth and space in the I/O system to avoid the data contention in the ATM. Basically, parts of the hot movies are replicated on the server unit. Most of the requests to the hot movie are directed to this unit. But if the server unit can not deliver the required video object within the required time limit (because of the large queue length) the video object is transported from the other server units through the ATM network. All the requests that are fulfilled locally by the server unit will not go through the network. Thus, the traffic through the ATM decreases on the expense of increasing the disk utilization.
摘要翻译：存储在视频服务器上的电影的数据组织方案。该方法利用I / O系统中的可用带宽和空间来避免ATM中的数据争用。基本上，部分热电影在服务器单元上复制。大多数对热门电影的要求都是针对本机的。但是，如果服务器单元无法在所需的时间限制内传送所需的视频对象（由于队列长度较长），则视频对象通过ATM网络从其他服务器单元传输。服务器单元在本地完成的所有请求都不会通过网络。因此，通过ATM的流量以增加磁盘利用率为代价降低。

摘要： A method is provided for managing memory resources in a service gateway environment. The method includes: receiving a service request, the service request having an associated memory space requirement that exceeds total available memory space associated with the gateway environment; determining a number of dependent service instances for each service instance; determining an accumulative memory space requirement for each service instance; identifying a subset of service instance whose memory space requirement exceeds the memory space requirement of the service request, the subset having a minimal number of the service instances; and performing a memory resource management operation in relation to the identified subset of service instances.

摘要： The disk scheduling system supports the processing of simultaneous storage device read and write requests in a video server environment, thereby supporting both video-on-demand and non-linear editing applications. Read requests are the result of movie viewing, while write requests are the result of video clip editing or movie authoring procedures. Due to real-time demands of movie viewing, read requests have to be fulfilled within certain deadlines, otherwise they are considered lost. Since the data to be written into the storage device is stored in main memory buffers (or write buffers), write requests can be postponed until critical read requests are processed. However, write requests still have to be proceeded within reasonable delays and without the possibility of indefinite postponement. This is due to the physical constraint of the limited size of the main memory buffers. The new process treats both read and write requests in a homogenous manner in order to ensure that the deadlines are met and avoids indefinite postponement and large buffer sized in the case of storage device writes utilizing a single queue of requests.

摘要： A multi-media file system for conmmunicating information between a multi-media client and a network storage device over a network. The file system includes a cluster that comprises one cluster manager and at least one file manager with each network storage device. The cluster manager is located on a client, includes an admission controller for controlling the admission of a request from a client for a file operation upon a selected file. A network bandwidth request from the admission controller is responded to by a network status determiner included in the cluster manager. The network status determiner determines the available network bandwidth. Each file manager is located on one of the clients. The file managers manage file maintenance procedures of corresponding files located on the network storage device. Each file manager includes a disk status determiner for determining the available disk bandwidth. The disk status determiner responds to a request from the admission controller.

摘要： Multi-media servers provide clients with streaming data requiring soft real-time guarantee and static data requiring a large amount of storage space. The servers use a pull-mode protocol to communicate with clients through a real-time network. Separate data and control channels enhance the soft real-time capability of the server. The data channel conforms to open standard protocol. A switched data link layer for the control channel permits separate intrahost control messages that may be multicast and broadcast. The distributed file system selects a specific data block size based upon the compression technique employed to enhance soft real-time guarantee. A hierarchal data structure combined with merging empty data blocks minimizes disk fragmentation. Data blocks are striped across multiple disks to improve disk utilization. A local buffer and a queue for both read and write requests provides support for simultaneous read and write data streams.
摘要翻译：多媒体服务器为客户端提供需要软实时保证的流数据和需要大量存储空间的静态数据。服务器使用拉模式协议通过实时网络与客户端进行通信。独立的数据和控制通道增强了服务器的软实时性能。数据通道符合开放标准协议。用于控制信道的交换数据链路层允许可以是多播和广播的单独的内部主机控制消息。分布式文件系统基于用于增强软实时保证的压缩技术来选择特定数据块大小。结合合并空数据块的层次数据结构最大限度地减少了磁盘碎片。数据块在多个磁盘之间进行条带化，以提高磁盘利用率。本地缓冲区和读取和写入请求的队列都支持同时读取和写入数据流。

摘要： The disk scheduling algorithms try to service a request with lower priority and strict deadline only if serving this request is not going to violate the deadline constraints of a higher priority request. One of the algorithms uses a single queue to hold all the requests regardless of their priority. The single queue is reorganized after the arrival of a new request according to the order requests would be serviced. A second algorithm uses multiple queues. Each queue holds only requests with the same priority, and the requests in each priority queue are sorted according to their deadlines. The decision of servicing a request is made at scheduling time.
摘要翻译：磁盘调度算法只有在服务该请求不会违反较高优先级请求的期限限制时，尝试以较低优先级和严格的限制时间来服务请求。其中一种算法使用单个队列来容纳所有请求，而不考虑它们的优先级。在根据订单要求提供服务的新请求到达后，重新组织单个队列。第二种算法使用多个队列。每个队列仅保存具有相同优先级的请求，并且每个优先级队列中的请求将根据其最后期限进行排序。处理请求的决定是在调度时间进行的。

摘要： Apparatus for determining a distance between two handwritten strings in a database. A processor extracts global features from each string. The processor divides the string into strokes, and identifies a plurality of bounding boxes. Each box contains a different stroke. The processor extracts global features from the suing, including: (1) a number of points; (2) a maximum angle between a first point in the string and a corner of the tallest bounding box; (3) a number of positive inversions; and (4) a number of negative inversions. The apparatus calculates the distance between the strings based on all of the numbers of points, maximum angles, numbers of positive inversions and numbers of negative inversions. A fixed query tree index may be formed. The tree has leaves and internal nodes belonging to multiple levels. A different key is associated with each level. Each key is a handwritten string. Each string is associated with one of the leaves, such that each child of each internal node in any of the levels between the one leaf and the root node is a root of a respective subtree. Each string associated with any leaf in the subtree which includes the one leaf is equally distant from the key associated with the one level, based on the global features. The tree is queried to search for a subset of the strings, such that each string in the subset is within a threshold distance of an input string, according to the distance function.
