Abstract: A first set of frames is received in a data flow and tagged with respective serial numbers identifying an ordering of frames in the first set. The tagged first set is forwarded to a general processor for processing prior to being sent to a remote network element. A data flow policy is received from the general processor based on processing of the first set. A second set of frames of the data flow are received subsequent to forwarding the first set to the general processor. It can be verified, based on the assigned serial numbers, that each frame in the first set has been sent to the remote network element prior to sending frames in the second set. The second set is processed and sent to the remote network element by the network processor, bypassing the general processor, based on the data flow policy.

Abstract: The present invention provides improved methods and devices for managing network congestion. Preferred implementations of the invention allow congestion to be pushed from congestion points in the core of a network to reaction points, which may be edge devices, host devices or components thereof. Preferably, rate limiters shape individual flows of the reaction points that are causing congestion. Parameters of these rate limiters are preferably tuned based on feedback from congestion points, e.g., in the form of backward congestion notification (“BCN”) messages. In some implementations, such BCN messages include congestion change information and at least one instantaneous measure of congestion. The instantaneous measure(s) of congestion may be relative to a threshold of a particular queue and/or relative to a threshold of a buffer that includes a plurality of queues.

A command is received from an attendee at the attendee endpoint device to display previously presented content of the presentation. The attendee endpoint device retrieves data for the previously presented content from the stored data. During the presentation (but without disrupting the presenter's presentation of the content), the attendee endpoint device displays the previously presented content from the retrieved data.

Abstract: Methods and apparatuses for providing a fairness protocol in a network element are disclosed herein. In accordance with the disclosed fairness protocol, the average bandwidth of traffic sourced from each of a plurality of ingress ports is monitored. The largest bandwidth of traffic sourced from a port within a first group of ingress ports (e.g., ingress ports of a network element) is identified and compared to the largest bandwidth of traffic sourced from a port within a second group of ingress ports (e.g., ingress ports of one or more network elements communicatively connected to the network element). In order to fairly allocate bandwidth when transmitting traffic that is sourced from the first and second groups, precedence is given to traffic flowing from the group associated with the identified port sourcing the lower bandwidth of traffic.

Abstract: Techniques are presented to reduce the number of antennas used for a transmission for a given antenna configuration and data rate. At a wireless communication device having a plurality of antennas and capable of sending a transmission via one or more of the plurality of antennas, a determination is made of a data rate and antenna configuration to be used for a transmission. A comparison is made between a total transmit power for a minimum number of antennas for the data rate to be used for the transmission and a total transmit power associated with the antenna configuration for the transmission. When the total transmit power for a minimum number of antennas for the data rate is greater than the total transmit power associated with the antenna configuration for the transmission, the transmission is sent with the minimum number of antennas.

Abstract: A notification is received that a network device in a computing network has blocked a service request directed towards a network resource of the computing network. A determination is made, based on authentication information associated with one or more of a network endpoint that transmitted the service request and a user at the network endpoint, as to whether the user should be notified of a reason that the network device blocked the service request. If it is determined that the user should be notified, a notification summarizing the reason that the network device blocked the service request is transmitted to the network endpoint.

Abstract: The present invention improves the performance of video on demand (VOD) in a digital cable system. A statistical remultiplexer (stat mux) acquires metadata that statistically describes the bandwidth characteristics of each VOD channel. When the metadata indicates that the VOD channel will require more bandwidth than is available, the stat mux can re-encode or re-compress other streams or the VOD stream streams to meet the bandwidth limitation. The metadata is generated off-line and streamed out ahead of the VOD program content. The stat mux includes a minimal length buffer for storing VOD program content that when combined with the metadata enables a viewer to randomly access VOD program content without noticeable latency. When a VOD function request is received from the viewer, the previously supplied metadata is used to allocate bandwidth rather than waiting for a look-ahead buffer to acquire a sufficient amount of future VOD program content.
