摘要： A network system (10), comprising a plurality of nodes (ERx, CRx). Each node in the plurality of nodes is coupled to communicate with at least one other node in the plurality of nodes. Each node of the plurality of nodes comprises a plurality of queues (32x) and is operable to perform the steps of receiving a plurality of packets and, for each received packet in the plurality of packets, coupling the received packet into a selected queue in the plurality of queues, wherein a respective selected queue is selected in response to the respective received packet satisfying one or more criteria. Each node of the plurality of nodes is also operable to perform the step of assigning a weight (Wx) to each respective queues in the plurality of queues. Each weight assigned to a respective queue in the plurality of queues is responsive to quality requirements for each packet in the respective queue and to a ratio of packet arrival variance in the respective queue and a mean of packets arriving to be stored in the respective queue during a time interval for minimizing the overall network traffic burstiness.

摘要： A method, computer readable medium, and system for advertisement and content distribution are provided. Supplementary content is synchronized with advertisement slots, or commercial intervals, of a program stream and distributed via separate multicast group addresses. The program content is distributed via an alternative multicast group address during commercial intervals. Ports associated with respective users are mapped or otherwise associated with multiple multicast group addresses in a forwarding table thereby allowing distribution of supplementary content, or alternatively the program content, during commercial intervals.

摘要： A network monitoring system (60). The system comprises storage circuitry (32) for storing network packet information, wherein the network packet information includes a predicted identifier. The network monitoring system also comprises at least one monitoring circuit (36) coupled to a network (70) along which network traffic flows in a form of packets. The at least one monitoring circuit programmed to perform the steps (44) of receiving a packet communicated along the network and determining whether the received packet is communicated between a source and destination in a first set of network nodes. Each packet in a sequence of communications between the source and the destination comprises a packet identifier that uniquely identifies the packet from all other communications in a flow between the source and the destination. The at least one monitoring circuit programmed to perform the step of, responsive to determining the received packet is communicated between a source and destination in the first set of network nodes, comparing the packet identifier of the received packet to the predicted identifier to determine an identifier deviation between the packet identifier and the predicted identifier for identifying an irregularity in the network traffic.

摘要： Dynamic delivery of different commercials to different viewers is achieved using a network node within an IPTV packet-switched network that is coupled to receive both a multicast television program and commercial programs. The network node is able to identify one or more subscribers to the multicast television program and to identify targeted commercial programs for each of the subscribers. The network node further includes a commercial inserter for inserting the respective targeted commercial program for each of the subscribers into the multicast television program to produce respective customized programs and to transmit the customized programs towards the respective subscribers.
