Adaptive Playout Scheduling for VoIP
|
|
|
This invention improves the quality of service (QoS) for Internet telephony. Due to network delay jitter, buffering at the receiver consumes a large part of the total end-to-end delay budget in order to reconstruct the voice packets in their periodic pattern. A new receiver-based playout scheduling scheme has been developed to reduce the packet buffering delay and packet loss. ...

The capacity of a path is defined as the minimum physical bandwidth among all the link traversed by a path. Such a link has been called the Narrow Link. Note that this notion of capacity is different from the available bandwidth, which is the minimum of the unused capacities among the link of a path. The capacity is fixed for a path, whereas the available bandwidth is time varying. Our focus is t...

The technology is a novel approach toward a functional application for optical quantum information cryptography and communication systems. Encoding quantum information achieves the highest level of reliability when single photons are used one at a time. If, however, more than one photon is pr...

System for Subnet Relocation
|
|
|
ISI / USC Researchers have developed a system for dynamically relocating Internet subnets. This system can securely relocate portions of a network to a location remote from the original network via an automation process for configuration and management, using a graphical interface and multipoint control channel to manage overlay deployment at the IP layer. An anchor site can provide a delegated IP...

Ultra-Compact, Rapidly Tunable Infrared Source
|
|
|
A rapidly tunable, ultra-compact, room temperature infrared source has been developed by University of California, Davis researchers. Over a very wide spectral range, the source provides continuous-wave and difference-frequency generation in a highly nonlinear optical semiconductor wave-guide. The integrated high power semiconductor lasers provide turntable pump and signal waves, used in:

Valence-Driven Connectivity Encoding for 3D Meshes
|
|
|
This technology is a new technique for lossless compression of triangle mesh connectivity using valence-driven, single-resolution encoding. This method uses an adaptive conquest over the mesh to transform the mesh into a sequence of valences and few additional codes. This sequence is then processed by an adaptive arithmetic encoder, which will use the low dispersion present in these valences to co...
