Bruce Booth - Ontario, CA
David W. Chow - Mundelein IL, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 12/28

US Classification:

37039553

Abstract:

A method, system and service for a data center computer network. A core network switches data using a first protocol layer. A first access switch is in electrical communication with the core network. The first access switch communicates the data to the core network using the first protocol layer. A second redundant access switch forms a first access switch pair with the first access switch. The second access switch is in electrical communication with the core network and communicates the data using the first protocol layer. The second access switch is in electrical communication with first access switch and communicates with the first access switch using a second protocol layer. The second protocol layer is at lower OSI level than the first protocol layer. The first access switch and the second access switch are configured to form a first VLAN. A first edge device is in electrical communication with the first access switch and the second access switch.

Abstract:

Mechanically-adjustable, variable oscillator drive mechanism having fixed locations for a main input shaft, an intermediate shaft, and an output shaft, and including a crank arm member supported by the intermediate input shaft and intermittently oscillated thereby through a fixed rotation, a slidable drive block member carried within a track formed on the crank arm, a positionally-adjustable carrier bracket mounted on the output shaft and pivotally supporting a sector gear segment, the latter also being drivably supported by the drive block member, and a sector pinion gear segment connected to the output shaft and meshed with the sector gear segment. Adjustment of the carrier bracket and connected sector gear segment, relative to the intermittently oscillating crank arm member, varies the angle of oscillation transferred to the sector gear segment, whereby the oscillation of the driven sector pinion gear segment and connected output shaft is adjustably varied. A combination adjustment and brake locking mechanism is provided to adjustably position the carrier bracket and sector gear segment and to clamp the carrier bracket at the selected operating position.
