摘要： An online tree quota check tool computes quota usage of files in a directory tree while the structure of the directory tree keeps changing due to concurrent write access by other applications and clients. The quota check tool computes the quota usage without interfering with the ongoing file access operations that change the directory content and quota usage. A quota check database keeps track of which files have been checked and which have not, so that each file is checked and its quota usage is accumulated once and only once while directories are moved and directory scans are restarted as a result of the changing directory content. File system operations are modified to synchronize with the online tree quota check. The quota check tool can be single threaded or multi-threaded. A multi-threaded tool dispatches idle directory iteration threads to scan subdirectories in the directory tree.
摘要翻译：在线树配额检查工具计算目录树中文件的配额使用，而目录树的结构由于其他应用程序和客户端的并发写入访问而不断变化。配额检查工具计算配额使用情况，而不会影响正在进行的文件访问操作，这些操作会更改目录内容和配额使用情况。配额检查数据库跟踪哪些文件已被检查，哪些文件没有被检查，以便每个文件被检查，并且其目录被移动并且由于更改目录内容而重新启动目录扫描时一次且仅存储一次的配额使用。文件系统操作被修改为与在线树配额检查同步。配额检查工具可以是单线程或多线程。多线程工具调度空闲的目录循环线程来扫描目录树中的子目录。

摘要： Message-wise unequal error protection is provided using codeword flipping to separate special and ordinary codewords without discarding any codewords. Special messages are encoded to ensure the codeword weight is less than a certain threshold weight. Ordinary messages are encoded to ensure the codeword weight is greater than the threshold weight. The bits of the codeword are flipped to enforce the weight criterion. Ordinary and special messages are encoded using different encodings to provide different levels of error protection. Upon receipt, codewords are separated into special and ordinary codewords for appropriate decoding. If a codeword is of indeterminate type, it is iteratively processed as both a special codeword and an ordinary codeword. The decoding result of each process is periodically checked to determine which decoding result satisfies decoding criteria.

摘要： A method and an apparatus for buffering and obtaining resources as well as a resource buffering system are disclosed. The method includes: obtaining an access popularity value of a resource from a database at intervals of a first preset time, and obtaining load values of cache servers from the database if determining that the access popularity value reaches a preset first threshold; and determining a duplication cache server for duplicating the resource according to the access popularity value and the load values, and notifying the duplication cache server to duplicate the resource from a cache server that stores the resource and buffer the resource. The method overcome the problems in the prior, namely, the same resource is buffered in only one cache server and the relatively idle cache servers are unable to share loads with busy cache servers. The method improves extensibility and working efficiency of the buffering system.
