摘要： A system and method are presented that enhance the performance of single and multiple-processor servers by taking advantage of the half-duplex nature of many HTTP requests. Upon receipt of an HTTP Get resource request, a single send and disconnect IRP is generated. The semantics of the send and disconnect IRP completion recognizes the half-duplex nature of the transaction by indicating a graceful close of the TCP/IP connection. This send and disconnect IRP is also completed without a queuing stage (queuelessly) on the processor that serviced the client request. To further enhance performance, the server FIN message to the client is included in the last data frame transmitted to the server. The invention also contemplates transmission of a single HTTP get and disconnect request by a client to allow acknowledgementless disconnection of the TCP/IP connection once a requested resource has been sent.
摘要翻译：提出了一种通过利用许多HTTP请求的半双工特性来提高单处理器和多处理器服务器性能的系统和方法。收到HTTP Get资源请求后，将生成单个发送和断开IRP。发送和断开IRP完成的语义通过指示TCP / IP连接的正常关闭来识别事务的半双工性质。这个发送和断开的IRP也在处理器上没有排队阶段（无间歇地）完成，为客户端请求提供服务。为了进一步提高性能，向客户端发送的服务器FIN消息包含在发送到服务器的最后一个数据帧中。本发明还考虑了一旦客户端发送单个HTTP获取和断开请求，一旦所请求的资源被发送，允许TCP / IP连接的无条件断开。

摘要： An opportunistic directory cache and method of usage reduce the number of calls between a client and server for file information, reducing the wastage of network resources and server resources. The expirable directory cache can be refreshed any time an appropriate directory enumeration call is made to the server, and is capable of being partially rather than completely invalidated in response to an indication that the file information of a file listed in the cache has or will change. If the affected file is identifiable, the entry in the cache for that file is invalidated, i.e. it is no longer useful for serving file information. If the affected file is not identifiable, then a first character projection of the file name is invalidated in the cache. In this manner, the directory cache is maintained with minimum resources and is persisted to the greatest extent possible, increasing its likelihood of usefulness.
摘要翻译：机会性目录缓存和使用方法可减少客户端与服务器之间的文件信息调用次数，减少网络资源和服务器资源的浪费。可以随时对服务器进行适当的目录枚举调用来刷新可终止的目录高速缓存，并且能够响应于缓存中列出的文件信息或将要改变的指示而部分地而不是完全无效。如果受影响的文件是可识别的，则该文件的高速缓存中的条目无效，即对于提供文件信息不再有用。如果受影响的文件不可识别，则文件名的第一个字符投影将在缓存中无效。以这种方式，以最小的资源维护目录缓存并且最大程度地持续存在目录缓存，从而增加其可用性。

摘要： A glare reduction system is disclosed including a display device configured for placement in a line of sight of an object. The display device includes a plurality of picture elements without a color filter. Each of the picture elements have a pair of spaced apart polarizing elements in substantially parallel orientation with respect to each other, and a liquid crystal element between the polarizing elements. An imaging source is provided to receive light from the object. The glare reduction system further includes a display driver to process the received light to generate a voltage signal, and selectively provide the voltage signal to one or more of the picture elements in order to regulate the opacity of the display device.

摘要： A host computing device has multiple instantiated copies of a legacy application. Each copy may issue a data request to access data at an absolute location common to all of the copies. To respond to the data request from a particular copy, it is determined that the absolute location of the data request has a redirection device specifying an alternate location, and the data request is dishonored. A unique location is determined from the alternate location and a unique ID of the particular copy of the legacy application, and the data request is re-issued to access the data at the unique location. Data requests from different copies of the legacy application are thus directed to different unique locations.

摘要： A method of purging cached open files from a client-side delayed close list on a remote file system. The remote file system stores a unique file identifier for each cached open file which is independent of the cached file's namespace. In response to a delete or rename command of a remote target file, the remote file system obtains a target file identifier from the target file's server. The remote file system then compares the target file identifier with each of the cached file's unique file identifier. If a cached file's unique file identifier matches the target file identifier, the cached file is purged from the delayed close list.

摘要： A method of tracing data on a network that detects receive and send events in a protocol stack is provided. The method provides key information for capacity planners for correctly charging network traffic to the individual services and applications. The TCP/IP stack is instrumented at the transport layer, so that Input/Output Request packets (IRP) representing sends and receives can be detected as they pass through the stack. When such packets are detected an appropriate send or receive event is recorded in a trace log.
