摘要： Technologies are described herein for detecting and managing congestion on a shared network link. A determination is made whether the shared network link is congested based on loss rate and round-trip time (RTT) between a computer and a receiver operatively coupled by the shared network link. Upon determining that the shared network link is congested, a back-off operation is performed on the computer. The back-off operation may reduce an allocated bandwidth of the computer on the shared network link by transforming a higher allocated bandwidth into a lower allocated bandwidth.
摘要翻译：这里描述了用于检测和管理共享网络链路上的拥塞的技术。基于由共享网络链路可操作地耦合的计算机和接收机之间的丢失率和往返时间（RTT），确定共享网络链路是否拥塞。在确定共享网络链路拥塞时，在计算机上执行退避操作。退避操作可以通过将较高分配的带宽转换为较低的分配带宽来减少共享网络链路上的计算机的分配的带宽。

摘要： It can be determined whether relative one way delay for data packets in a data stream exceeds a delay threshold. If so, then a delay congestion signal indicating that the relative one way delay exceeds the delay threshold can be generated. The delay congestion signal can be used in calculating an adaptive bandwidth estimate for the data stream. A packet loss rate congestion signal may also be used in calculating the bandwidth estimate. It can be determined whether a data stream of data packets is in a contention state. If the data stream is in the contention state, then an adaptive bandwidth estimate can be calculated for the data stream using a first bandwidth estimation technique. If the data stream is not in the contention state, then the bandwidth estimate for the data stream can be calculated using a second bandwidth estimation technique.

摘要： Accordingly a method and interface allows an attribute data base used by an Information Manager to be quickly populated and accurately maintained. A single Bulk Attribute Retrieval Request triggers the primary storage device to collect object attribute information. The method allows for selective collection of objects and attributes by providing filters and attribute lists in the Requests. The Request may be used to provide an incremental scan with appropriate time stamp filtering. In addition, the size of the results can be controlled by the IM by eliminating attributes that are not of interest to the IM. The Request is advantageously issued over a FileMover interface, which is an HTTP connection, and encoded in XML, allowing the IM to easily customize the Request as desired.

摘要： A write interface in a file server provides permission management for concurrent access to data blocks of a file, ensures correct use and update of indirect blocks in a tree of the file, preallocates file blocks when the file is extended, solves access conflicts for concurrent reads and writes to the same block, and permits the use of pipelined processors. For example, a write operation includes obtaining a per file allocation mutex (mutually exclusive lock), preallocating a metadata block, releasing the allocation mutex, issuing an asynchronous write request for writing to the file, waiting for the asynchronous write request to complete, obtaining the allocation mutex, committing the preallocated metadata block, and releasing the allocation mutex. Since no locks are held during the writing of data to the on-disk storage and this data write takes the majority of the time, the method enhances concurrency while maintaining data integrity.
摘要翻译：文件服务器中的写接口提供对并发访问文件数据块的权限管理，确保文件树中间接块的正确使用和更新，扩展文件时预分配文件块，解决并发读取的访问冲突并写入同一个块，并允许使用流水线处理器。例如，写入操作包括获得每个文件分配互斥（互斥锁），预先分配元数据块，释放分配互斥体，发出用于写入文件的异步写入请求，等待异步写入请求完成，获得分配互斥体，提交预先分配的元数据块，并释放分配互斥体。由于在将数据写入磁盘存储器期间没有锁定，并且此数据写入占用大部分时间，因此该方法在保持数据完整性的同时增强了并发性。

摘要： Read-only and read-write snapshot copies of a production file in a Unix-based file system are organized as a version set of file inodes and shared file blocks. Version pointers and branch pointers link the inodes. Initially the production file can have all its blocks preallocated or it can be a sparse file having only an inode and its last data block. A protocol is provided for creating read-only and read-write snapshots, deleting snapshots, restoring the production file with a specified snapshot, refreshing a specified snapshot, and naming the snapshots. Block pointers are marked with a flag indicating whether or not the pointed-to block is owned by the parent inode. A non-owner marking is inherited by all of the block's descendants. The block ownership controls the copying of indirect blocks when writing to the production file, and also controls deallocation and passing of blocks when deleting a read-only snapshot.

摘要： A video conference cross-links at least a portion of the clients for point to point communication while still using a video conference server. The video conference server continues to manage some aspects of the video conference for the cross-linked clients and may be configured to perform audio/video processing for some of the clients in a video conference. For example, the video conference server may perform audio/video processing and routing of streams for clients that do not have the capabilities to perform the processing directly. Clients that are able to process their audio/video needs may directly connect to other clients through cross-links while still using the video conference server for management.
