Inventors:

David Joyner - Raleigh NC, US

Assignee:

Spirent Communications, Inc. - Sunnyvale CA

International Classification:

G01R 31/08

Appl. No.:

12/464639

Inventors:

David Joyner - Raleigh NC, US
Kris Rousey - Raleigh NC, US

Assignee:

Spirent Communications, Inc. - Calabasas CA

International Classification:

H04L 12/56

US Classification:

37039553

Abstract:

Methods, apparatuses, data structures, and computer readable media are disclosed that perform emulated processing of packets communicated via a physical port between emulated network devices and real network devices. The emulated processing performs forward equivalence class classification on the packets. The forward equivalence class classification varies with the contents of the packets, and subsequent to the forward equivalence class classification the emulated processing varies with particular successful classifications resulting from the forward equivalence class classification.

US Patent:

52318630, Aug 3, 1993

Filed:

Apr 24, 1992

Appl. No.:

7/873141

Inventors:

David W. Joyner - Wilmington NC
James C. Risley - Carolina Beach NC
Grover T. Henry - Burgaw NC

Assignee:

General Electric Company - San Jose CA

International Classification:

B21D 3920

US Classification:

723421

Abstract:

To facilitate safe loading of a thermal sizing mandrel in an elongated channel of open rectangular cross section, a corner rod die is first lowered into a fixture, and then a channel is lowered into the fixture to a vertical position surrounding the die. A mandrel is inserted downwardly through the channel open interior to press corner rods of the die outwardly against the channel corners to elastically reform the channel substantially to a specified geometry. Mandrel insertion is facilitated by inducing vibratory energy therein and by forming shoes in the fixture acting against the channel outer sides to square off the mandrel cross section in advance of mandrel insertion.

Appl. No.:

15/857483

Inventors:

- San Jose CA, US
David Joyner - Raleigh NC, US

Assignee:

Spirent Communications, Inc. - San Jose CA

International Classification:

H04L 29/08
G06F 11/34
H04L 12/24
H04L 12/911
G06F 9/50

Abstract:

A utilization test generates the multiple dimensions of resource load on the first computer, the multiple dimensions including at least two of: a processor utilization dimension, a main memory utilization dimension, a mass storage utilization dimension, and a network utilization dimension. The utilization test performs iterations of attempts to generate said each dimension of the resource load on the first computer, in an amount equal to a changeable target utilization of said each dimension of the resource load on the first computer. The utilization test adjusts the adjusted utilization to attempt to correct for inequality between (i) the actual utilization of a particular one of the multiple dimensions of the resource load on the first computer, and (ii) the changeable target utilization of the particular one of the multiple dimensions of the resource load on the first computer.
