Abstract: The adaptive bandwidth throttling system implements a graceful diminution of services to the clients by delaying a first class of services provided by a network server in response to the effective bandwidth utilized by this network server exceeding a first threshold. If the demand for the bandwidth by this network server exceeds a second threshold, the bandwidth throttling system escalates the throttling response and blocks the first class of services from execution and can also concurrently delay execution of a second class of services. The implementation of the throttling process can be varied, to include additional levels of response or finer gradations of the response, to include subsets of a class of services. In addition, the threshold levels of bandwidth used to trigger the throttling response can be selected as desired by the system administrator.

Abstract: The adaptive bandwidth throttling system implements a graceful diminution of services to the clients by delaying a first class of services provided by a network server in response to the effective bandwidth utilized by this network server exceeding a first threshold. If the demand for the bandwidth by this network server exceeds a second threshold, the bandwidth throttling system escalates the throttling response and blocks the first class of services from execution and can also concurrently delay execution of a second class of services. The implementation of the throttling process can be varied, to include additional levels of response or finer gradations of the response, to include subsets of a class of services. In addition, the threshold levels of bandwidth used to trigger the throttling response can be selected as desired by the system administrator. Typically, once the effective bandwidth utilization is approximately equal to the allocated bandwidth for the network server, the first level of the hierarchical bandwidth throttling is activated. The second level of the hierarchical bandwidth throttling is activated once the effective bandwidth utilization exceeds the allocated bandwidth for the network server by greater than a predetermined amount.

Abstract translation: 自适应带宽限制系统通过延迟由网络服务器提供的第一类服务来响应于超过第一阈值的该网络服务器使用的有效带宽，实现对客户端的服务的优雅的减少。 如果该网络服务器对带宽的需求超过第二个阈值，则带宽限制系统会升级调节响应，并阻止第一类服务执行，并且还可以同时延迟第二类服务的执行。 节流过程的实施可以有所不同，包括响应的更多级别或更高级别的响应，以包括一类服务的子集。 此外，可以根据系统管理员的需要选择用于触发节流响应的阈值阈值。 通常，一旦有效带宽利用率大致等于网络服务器分配的带宽，则激活分层带宽限制的第一级。 一旦有效带宽利用率超过网络服务器的分配带宽大于预定量，则层次化带宽限制的第二级别被激活。

Abstract: A session manager has a session timeout mechanism to selectively timeout client-server sessions. The session timeout mechanism has multiple timeout buckets to hold corresponding groups of sessions according to the sessions' timeout periods. Sessions located in different ones of the timeout buckets are set to timeout at different times. The session manager also has a session timeout clock that is incremented every predetermined time unit (e.g., every minute). The session timeout clock maintains a pointer to one of the timeout buckets and advances that pointer with each clock increment. The session timeout clock advances the pointer through all of the timeout buckets, one bucket at a time. The session timeout clock advances the pointer repeatedly through all the buckets. The cycle time for the session timeout clock to reference every timeout bucket is equal to the incremental time unit multiplied by the number of buckets. A new session (or one that recently received a request and is restarting its timeout period) is inserted into a timeout bucket that is one or more buckets ahead of the clock pointer, depending upon the session's timeout period. When the timeout clock references a particular bucket, the sessions in that bucket are analyzed for possible timeout. Sessions whose timeout period has run without receiving any new requests are timed out and removed from the bucket.

Abstract translation: 会话管理器具有会话超时机制，以选择性地超时客户端 - 服务器会话。 会话超时机制具有多个超时桶，以根据会话的超时时间段保存对应的会话组。 位于不同超时桶中的会话在不同时间设置为超时。 会话管理器还具有每预定时间单位（例如，每分钟）递增的会话超时时钟。 会话超时时钟保持指向其中一个超时桶的指针，并使每个时钟增量的指针前进。 会话超时时钟使指针通过所有超时桶，一次一个桶。 会话超时时钟将重复指针移到所有的桶中。 会话超时时钟引用每个超时桶的周期时间等于增量时间单位乘以桶数。 根据会话的超时时间，新会话（或最近收到请求并正在重新启动其超时时间）被插入超时时钟指针前面的一个或多个存储桶的超时桶。 当超时时钟引用特定存储桶时，将分析该存储区中的会话可能的超时。 超时时间没有收到任何新请求的会话超时并从存储桶中删除。

Abstract: A bandwidth throttling system is implemented on a server network connected to a computer network system to serve one or more clients over a network. The network server supports a service that presents multiple virtual services that can be individually requested by the clients. The bandwidth throttling system controls bandwidth on a per virtual service basis. The bandwidth throttling system has a measuring subsystem to measure the amount of bandwidth being used by each virtual service supported by the network server. The bandwidth throttling system also has a control subsystem to selectively throttle requests for a particular virtual service independently of others based upon the bandwidth used by the particular virtual service. The bandwidth throttling system utilizes an adaptive, hierarchical throttling strategy that is applied to each virtual service independently. The bandwidth throttling system compares the bandwidth usage for the virtual service against the administrator-defined thresholds for that virtual service. If the presently used bandwidth exceeds a first threshold, a first set of throttling actions is applied. If the presently used bandwidth exceeds a second threshold greater than the first threshold, a different second set of throttling actions is applied. In this manner, the administrator is given maximum control at setting throttling policies for each individual virtual service independently of other virtual services.

Abstract: A system for generating message headers where previously saved message headers are retrieved from memory when needed to satisfy a message header requirement. Message headers are comprised of segments where each message header segment has a different lifetime. In particular, a file-object response message header includes a header segment containing information linked to the requested file-object. This file-object linked header segment is retrieved when needed from a file-object header cache. A file-object response message header includes other segments such as one containing time-variant global information and time-invariant global information. Building header messages from multiple segments retrieved from their respective cache memories saves significant processing time as compared to generating a new message header each time a header is required by operation of a network server application.

Abstract: Methods and devices for encoding and interleaving data packets for broadcast and for de-interleaving and decoding data packets in a communication system eliminate detrimental biasing effects by using pseudo-random M-sequence bit encoding as part of the turbo encoding and decoding. The use of pseudo-random M-sequence bit encoding mitigates biasing effects that may otherwise be introduced if conventional r-c interleaving is applied to long turbo encoded data which would degrade reception in the presence of broadcast interference.

Abstract: Techniques for multiplexing multiple data streams using frequency division multiplexing (FDM) in an OFDM system are described. M disjoint “interlaces” are formed with U usable subbands. Each interlace is a different set of S subbands, where U=M·S. The subbands for each interlace are interlaced with the subbands for each of the other M−1 interlaces. M slots may be defined for each symbol period and assigned slot indices 1 through M. The slot indices may be mapped to interlaces such that (1) frequency diversity is achieved for each slot index and (2) the interlaces used for pilot transmission have varying distances to the interlaces used for each slot index, which improves channel estimation performance. Each data stream may be processed as data packets of a fixed size, and different numbers of slots may be used for each data packet depending on the coding and modulation scheme used for the data packet.

Abstract: Reference free tracking of position by a mobile platform is performed using images of a planar surface. Tracking is performed optical flow techniques, such as pyramidal Lucas-Kanade optical flow with multiple levels of resolution, where displacement is determined with pixel accuracy at lower resolutions and at sub-pixel accuracy at full resolution, which improves computation time for real time performance. Periodic drift correction is performed by matching features between a current frame and a keyframe. The keyframe may be replaced with the drift corrected current image.

Abstract: A repeated integral images method filters image data in only two passes, e.g., the first pass filters horizontal rows of pixels and a second pass filters vertical columns of pixels, or in a single pass. The filter performs at least one infinite impulse response (IIR) filter and at least one finite impulse response (FIR) filter on the image data. A plurality of IIR filters and FIR filters maybe performed to approximate a Gaussian filter. By minimizing the number of passes, the data flow between the processing unit and the storage unit is greatly reduced compared to conventional repeated integral images method thereby improving computation time.
