Title:
COMPUTER NETWORK PHYSICAL-LAYER ANALYSIS METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO2000039594
Kind Code:
A3
Abstract:
A method and system for computer network physical layer analysis is described using signal analysis techniques and beginning with time-domain responses to yield highly quantitative analysis of the computer network's physical layer. Specifically, multiple transmissions are accumulated into a composite response of the computer network link. This composite response is then used as the basis for analysis of the computer network link. Further, an automated process is described for location of an arbitrary termination of a link.
