The source node terminal nodes send IP packets over the plurality of c-nodes to the destination terminal nodes to arbitrary groups of the destination terminal nodes.

Abstract: There is provided a system and method for providing a simple yet flexible overlay network on top of any IP networks to enable diverse network applications whereby much of the rigidities of IP protocol suite are eliminated without any modifications to the applications. In particular, the system includes: a plurality of c-nodes; one or more source terminal nodes connected to an IP network; and one or more destination terminal nodes connected to the IP network. Here, the source terminal nodes send IP packets over the plurality of c-nodes to the destination terminal nodes to accomplish arbitrary communications between arbitrary groups of the source terminal nodes to arbitrary groups of the destination terminal nodes. More specifically, a method employing the system utilizes the concept of connection ID and headers that can be inserted anywhere in the IP packet.

Abstract: There is provided an architecture (system and method) to accelerate web response time and to provide a level platform to meet the interests from both providers and users of content. The concept of user object is introduced to present user interests or disinterests. If a user's browser has already cached a particular provider object, then a corresponding user object indicates that the user is not interested in that object. Otherwise, a user can indicate his/her interests in objects specified either by a set of criteria or explicit description of objects. The web response is accelerated by generalization of the split-proxy architecture of content networking. The user is represented by the user proxy and browser proxy 34. Unlike the traditional content delivery architecture, the content procurement architecture pushes user interests close to the provider sites and minimizes the request-response time between the user proxy and the provider proxy.

Abstract: A system and method is provided that comprise a logical central controller; and a plurality of logical nodes; wherein a demand is performed such that to transport various commodities from a first set of at least one nodes among the plurality of logical nodes to a second set of at least one node of the plurality of logical nodes is achieved; and wherein said nodes are interconnected by directed links according to a graph, said commodities are allowed to be transported only on said directed links, simultaneous arrival (referred to as collision) of commodities at a node is lost, each transportation of said commodities across a directed link incurs.

Abstract: There is provided a method of delivering a plurality of source streams from a plurality of servers to a plurality of clients through a plurality of routers over a communication network using a pay-per-period pricing scheme. Said method includes: splitting the source stream into a plurality of sub-streams to the routers; estimating available capacities of the plurality of the routers; and delivering the sub-streams to the routers at transmission rates proportional to the available capacities of the routers. The available capacity is estimated based on input and output traffic correlations in the server. Further, the client, who is not an owner of the available capacity, may be allowed to use the available capacity at a lower priority than that of the owner. The delivery of the source stream may be carried out over a plurality of paths over the communication network, wherein time-space trajectories of the paths do not cross each other.

Abstract: An apparatus and method for minimizing nonlinear distortions in computer system communications where the upstream signal from a client modem to a server modem is periodically sampled, the samples being utilized by a non-linear decision feedback equalizer to periodically produce sets of equalizer coefficients. The equalizer coefficients are sent via an independent communication channel downstream to the client modem to continuously update distortion-minimizing adjustments to the client modem's upstream output. The samples are taken periodically in order to update the non-linear decision feedback equalizer so that it can provide appropriate equalizer coefficients for the changing characteristics of the upstream signal. The method includes identifying, by a first communication system, nonlinear equalization parameters to be used by a second communication system to minimize nonlinear distortions on a primary communication channel.

Abstract: An echo canceler for calculating an echo impulse response during a training sequence, wherein a sequence of data samples is selected such that a full rank data correlation matrix comprised of such data samples is diagonal at the Nth iteration. The echo canceler estimates the echo impulse response based on such data samples and an echo generated during the training sequence using a normalized least means square algorithm, wherein the length of the data sequence to sound the echo channel is N. This normalized LMS algorithm, wherein the data sequence is specifically selected, converges toward an echo impulse response much faster than standard LMS algorithms, while having a computational complexity comparable to that of the standard LMS algorithm.

Abstract: The present invention is a fully connected feed forward network that includes at least one hidden layer 16. The hidden layer 16 includes nodes 20 in which the output of the node is fed back to that node as an input with a unit delay produced by a delay device 24 occurring in the feedback path 22 (local feedback). Each node within each layer also receives a delayed output (crosstalk) produced by a delay unit 36 from all the other nodes within the same layer 16. The node performs a transfer function operation based on the inputs from the previous layer and the delayed outputs. The network can be implemented as analog or digital or within a general purpose processor. Two teaching methods can be used: (1) back propagation of weight calculation that includes the local feedback and the crosstalk or (2) more preferably a feed forward gradient decent which immediately follows the output computations and which also includes the local feedback and the crosstalk.
