摘要： An arrangement (apparatus and method) for monitoring jitter caused during transport of digitally-coded information in a packet switched network, and for managing network operations in accordance with the detected jitter. The detected jitter is used to determine whether corrective action is necessary, such as rerouting network traffic, or performing network maintenance. The disclosed arrangement detects program clock reference (PCR) values from an MPEG-encoded transport stream, whereby each pair of PCR values represents an expected arrival time of a corresponding stream segment. An actual arrival time for the corresponding stream segment is determined in response to detection of the corresponding PCR values and an independent clock signal. The expected arrival time of the stream segment and the actual arrival time are correlated with an accumulation of expected and actual arrivaimes of previously-received data packet stream segments in order to determine the jitter in the digital data stream. The jitter is corrected by a combination of adaptive buffering techniques and restamping the PCR value with corrected values coinciding with the actual arrival time of the stream segments.

摘要： An arrangement (apparatus and method) for dynamically provisioning infrastructure components in a digital communication network using an object-oriented relational paradigm. A network configuration system, also referred to as a video support system, stores all related information on each of the infrastructure components (IFCs) as objects in an object oriented relational database, including the functions, capabilities, locations, when and how the IFCs are assigned, and the capacities, working and spare, existing in and between various locations. The objects are arranged into clusters based on common characteristics, and the object clusters (modules), selectively access other modules to provide functional and logical connections independent from nonrelevant objects, such as physical location. Entity relationships establish the relevancy of different objects and object clusters. The object-oriented relational paradigm allows new technology devices to be added to the infrastructure, and enables intelligent infrastructure components to perform dynamic and adaptive configurations with minimal modification in the provisioning system.
