Abstract: A method for video-on-demand (VoD) admission control at a network edge assigns to a triple-play network virtual topology lesser resources than there exists in a corresponding underlying physical link bandwidth. This prevents video-on-demand (VoD) starvation of data-class traffic. At least one policy enforcement point (PEP) is attached to an edge of the network, providing for autonomous short-term, application-aware controls to be applied to corresponding network ingress traffic, and also providing for long-term controls on corresponding network ingress traffic. The network ingress traffic to the network comes under management when the traffic nears or exceeds network capacity. It is enabled to do so by computations of current network routing topology and bandwidth reservations. Path tables are used to calculate if a PEP may admit more, or must shed, sessions/calls to maintain service for other existing application traffic.

Abstract: An application-aware policy enforcement point (PEP) attaches to the edge of a packet-switched network to manage loading when the network nears or exceeds its capacity due to changes in the network, e.g., component failures or incremental growth. An advanced bandwidth manager (ABM) comprises a session/call admission controller (S/CAC) that monitors and maps ever-changing network topology information gathered from remote listeners about how traffic is being routed through various parts of the network. These reports are harmonized to build a single view of the network topology, and the point-to-point connections are abstracted into path tables. Autonomous PEP's at the network's edges provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. The S/CAC uses the path tables to calculate whether particular PEP's can admit more traffic, or should they shed sessions/calls to keep service up for the existing application traffic.

Abstract: A method of communicating individual packets i of K bits includes permutation mapping of the packets, with each permuted packet being denoted by ?n(i), wherein ?n is a permutation on K letters that is unique for each packet transmission. Each permuted packet ?n(i) is modulated to provide a complex vector x(?n(i)) for each packet. The packets are transmitted over a AWGN channel so each individual packet i is received as a variable of the vector x(?n(i)) in a complex vector yn=x(?n(i))+vn, wherein n represents the sequential number of the transmission attempt for a particular packet and vn represents noise. This method enables the packets to be transmitted while using an improved ARQ routine that includes soft-combining decisions and a constant constellation with a constellation complexity greater than two bits/symbol to thereby significantly improve ARQ-routine performance over the current state of the art.

Abstract: A user leaving an ad-hoc network is detected and a corresponding sequence of commands are executed independently of surrounding conditions.

Abstract: A policy enforcement point (PEP) attaches to the edge of a packet-switched network to manage loading when the network nears or exceeds its capacity due to changes in the network, e.g., component failures or incremental growth. Autonomous PEP's at the network's edges provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. Changes become necessary when a network event results in a loss of resilient bandwidth that effects the traffic class under admission control. Or, when an unexpected surge in traffic exceeds the PEP's reserved resources to a particular destination. The resources available across the network are recalculated for minimizing impact on existing sessions or calls, and it informs the PEP's of the new resources available. If the new maximum exceeds the current utilization to that destination, the PEP invokes a local priority drop mechanism to back off the traffic until it is under the new limit.

Each level of detail is periodically broadcast. The levels of detail may be shown by themselves or combined at a receiver to create segmented views of the stroke data. A user can select a coarse view of the stroke data to quickly see the stroke history. Additionally, techniques are provided for quickly and repeatedly accessing data elements in already existing data structures. Generally, a description is created that describes data elements in a preexisting data structure.
