Multi-purpose network diagnostic modules

Abstract

The present invention provides for flexibly configurable network diagnostic modules that can implement any of a plurality of network diagnostic functions. A network diagnostic module receives an indication that a selected network diagnostic function (e.g., network analyzer, jammer, generator, bit error rate tester, etc.) is to be implemented. The network diagnostic module receives a bit file with instructions or data for implementing the selected network diagnostic function at one or more ports. The network diagnostic module identifies a programmable logic module (e.g., a Field Programmable Gate Array ('FPGA')) that controls the one or ports. The network diagnostic module loads a portion of the bit file at the identified programmable logic module to cause the programmable logic module and the one or more ports to interoperate to implement the selected network diagnostic function. A plurality of network diagnostic modules can be included in a common computer system chassis.

Description

technical field [0001] The present invention generally relates to identifying causes of performance deviations and other problems in high speed data transmission systems and components. More specifically, embodiments of the present invention relate to a configurable diagnostic module that can perform a variety of different diagnostic tests suitable for use with a variety of different network protocols and configurations. Background technique [0002] Computer and data communication networks continue to proliferate due to falling costs, increased performance of computer and networking equipment, and increased demand for communication bandwidth. Communication networks—including wide area networks (“WANs”), local area networks (“LANs”), and storage area networks (“SANs”)—through the sharing of resources, delivery of voice and data, and processing of voice, data, and related )—allows for increased productivity and utilization of distributed computers or stations. Also, as orga...

Problems solved by technology

[0016] Also, when a card manufactured for a specific diagnostic function fails, the administrator is generally required to purchase a replacement card

Also, the mechanisms for modifying the card's functionality are limited, if any

For example, it is generally quite difficult to modify a jammer card to perform the function of a bit error rate tester card
