An adaptive rate management method and system for adapting a receiver rate to a transmission rate in a packet switch network comprises determining an error value at a sample rate, obtaining an updated accumulator value based on said error value Es at a decimated sample rate, and generating an appropriate rate command and changing said accumulator value at the decimated rate based on the updated accumulator value. The method may be adapted for either adapter point management or bit stuffing. When applied to adapter point management (APM), the method generates pointer adjustments for rate management. In a frequency locked APM preferred embodiment of the method and system, pointer adjustments in an interval are generated at a constant rate based on an average pointer adjustment value calculated in previous intervals.

A method and apparatus are provided for optimizing retrieval of network resources. In one embodiment, a method of optimizing access to a network resource is implemented in a computer program executed by a router, cache server, or proxy server. A network resource that contains one or more embedded symbolic host name references is received. A network address corresponding to each of the embedded symbolic host name references is determined. A modified copy of the network resource is created and stored; in the modified copy, a network address is substituted for each corresponding embedded symbolic host name reference. Thereafter, the modified copy of the network resource in responding to all subsequent client requests for the network resource, thereby greatly reducing the required number of network address lookup operations. In one specific embodiment, IP addresses are determined using DNS queries for the hostname portion of all URLs that are embedded in a Web page using image, applet, object, or embed tags. The IP addresses are stored in place of the hostname portions in a modified copy of the Web page, typically in a cache. As a result, when the modified page is subsequently served to clients, the clients need not carry out DNS resolution of all the embedded URLs, resulting in reduced network message traffic and more rapid page display.

A method, apparatus, and computer-readable medium configured for maintaining consistent per-hop packet forwarding behavior among a plurality of network devices in a network within a Differentiated Services (DS) domain are disclosed. In one aspect, a method involves creating and storing a network-wide PHB definition that associates a PHB with a DS code point (DSCP) value, and with a set of parameters that define the bandwidth and buffer resources allocated to the PHBs on all interfaces of network devices within the DS domain. A mapping of each of the PHBs in the network-wide PHB definition to one or more queues of the network devices is determined. Drain size and queue size values are determined for each of the queues to which PHBs are mapped. A mapping of each of the PHBs to a threshold value associated with the queues is determined. Parameters of fragmentation and interleave mechanisms are determined. Network device configuration parameter values based on the mappings, the drain size, and the queue size, etc. are sent to each of the network devices within the DS domain. As a result, consistent PHB is achieved throughout a network using abstract definitions of PHBs.

A process for determining responders in clinical testing environments that involves, inter alia, detecting treatment response through the use of small numbers of measurements of randomly varying outcome variables in individual clinical trial subjects, and by analyzing the measurements in such a way as to eliminate troublesome variables, such as a spontaneous population variability.
