Title: Innovations of Patrick L DeAngelis

Introduction

Patrick L DeAngelis is a notable inventor based in Northborough, MA (US). He has made significant contributions to the field of network switching technology, holding a total of five patents. His work focuses on enhancing the efficiency and functionality of network switch fabrics.

Latest Patents

One of his latest patents is related to switch fabric testing. This method allows for the testing and verification of an off-line switch fabric used in network switches that have redundant switch fabrics. A special test cell is directed to the off-line switch fabric, loops through a portion of the switching core, and is returned from the off-line switch fabric. A plurality of test cells can be utilized to provide full mesh connectivity checking of the off-line switch fabric. This testing is accomplished without the need for reconfiguration of the off-line switch fabric, ensuring that it is available for use immediately upon determination of the need.

Another significant patent involves the cell combination to utilize available switch bandwidth. This apparatus and method enable the combination of multiple streams of data cells into a single thread. By allowing plural input ports of an intermediate device to access a single parallel output port, multiple network switch elements can share a single thread through a switch fabric. This method permits interleaving the relatively low bandwidth cell outputs of two ATM network switch central control processors onto a single thread routed through an interconnected switch fabric. Pacing of cells provided to the plural serial input ports prevents exceeding the shared thread bandwidth.
