Abstract: A streaming measurement agent designed to experience, measure, and report on a media stream as an actual end user would experience the stream. Preferably, agent resides transparently within a streaming media player itself so that it can monitor stream packet flows within the player as the measured streams are being played. In an illustrative embodiment, the agent comprises a performance monitoring module (PMM), which is software that resides in an interface between an existing core module and a renderer of a media player. The agent PMM intercepts each useful packet as it goes from the core to the renderer and, as a result, it is able to compute quality metrics about the playback. The agent functions “transparently” to the media player by presenting the core with an application programming interface (API) that emulates the API that the renderer normally presents to the core.

Abstract: A plurality of computer nodes communicates using seemingly random IP source and destination addresses and (optionally) a seemingly random discriminator field. Data packets matching criteria defined by a moving window of valid addresses are accepted for further processing, while those that do not meet the criteria are rejected. In addition to “hopping” of IP addresses and discriminator fields, hardware addresses such as Media Access Control addresses can be hopped. The hopped addresses are generated by random number generators having non-repeating sequence lengths that are easily determined a-priori, which can quickly jump ahead in sequence by an arbitrary number of random steps and which have the property that future random numbers are difficult to guess without knowing the random number generator's parameters. Synchronization techniques can be used to re-establish synchronization between sending and receiving-nodes.

Abstract: Techniques for controlling a network connection in accordance with connection information associated with a destination location on a network are disclosed. Controlling of the network connection in accordance with connection information associated with the destination location can be achieved in a variety of ways. One way is in the selection of a network transport (e.g., bearer selection). Another way is in the configuration of parameters associated with the connection (i.e., connection parameters). In either case, the connection information includes information with which the selection of the network transport and/or connection parameters can be made. The controlling of the network connection impacts quality of service provided to a requestor that is requesting use of the connection.

Abstract: Methods and systems are provided which convey access control information from a first server to a second server through an end user device, for example in a system in which these servers and devices are all connected to the Internet. The method starts after the first server receives a message from the end user device. The first server in response to this message from the end user device sends a response message to the end user device containing the access control information to be conveyed to the second server, optionally after performing authentication. The response message also contains an instruction for the end user device to post a second message to the second server containing the information. The information is preferably contained in a content portion of the message. A hidden form may be used in the response message to contain the information. Optionally, the end user may be presented with an option to post the second message or not.

Abstract: An HDLC formatter and a message processing core exchange messages over a high speed message exchange interface. The interface includes a memory shared by the HDLC formatter and the message processing core. A handshaking arrangement is used to coordinate message storage and retrieval in the shared memory by the HDLC formatter and the message processing core with minimal utilization of processing resources of the message processing core. This handshaking coordination, together with the use of a message buffer accessed by the HDLC formatter to buffer channelized messages exchanged with the message processing core, facilitates message processing on multiple serial links (e.g., 3) over multiple timeslots (e.g., 256).

Abstract: A load balancing device according to an embodiment of the invention uses a predictor that comprises a plurality of Least Connections Control Blocks (LCCBs) that keeps track of the real servers with active connections. To speed up the search for the real server with the least number of active connections, an LCCB is kept for each metric. A metric is defined as the number of connections on a server divided by its weight (or capacity) of the server. This metric is kept as a quotient/remainder pair. The predictor sends out the real server address with the lowest metric whenever a new connection is required by the load balancing device.

Abstract: The invention is a method and apparatus for detecting page load abandons in real time. Particularly, a page includes code that generates a unique record correlation ID that identifies the particular page that is being loaded and the particular instance of its loading and embeds that ID in two special tags in that page. The first tag is at the top of the page and the second tag is at the bottom of the page. The first tag causes the client to send a request to a Usage Analyzer server including the unique record correlation ID. The Usage Analyzer server receives this request and creates a log entry bearing the ID and sets a page load abandon flag for that log entry. If the page finishes loading, the client machine encounters the second tag. That tag causes the client to send another request to the Usage Analyzer server with the same ID. When the Usage Analyzer server receives this request, it resets the page load abandon flag.
