Implementation of a simple device mediation application of a Network Management System

Abstract
In a typical NMS scenario a network service provider will have thousands of network elements of different kinds like eg, switches, routers, bridges, gateways and also of various makes eg, Cisco, Juniper, Nortel, etc. All these network elements would like to collect data spewed out by these elements. This data will be analyzed for Faults, Configura ....etc

A Linux Device Driver for USB to USB Direct Link Device

The first version of the Universal Serial Bus (USB) specification was released in January 1996. In April 2000, version 2.0 of the USB specification, which supports transfer rates up to 480 Mbps, was released. Because of its low cost, high data-transfer rate, ease of use, and flexibility, USB has gained wide acceptance in the computer industry. Today, many peripherals and devices connect to computers through USB interfaces. Currently, most general-purpose operating systems pro ....etc
