Introduction
The purpose of this assignment is to design and recommend a full network infrastructure for China Steel Ltd, a steel works organisation in China. The company have plants in every province throughout the country but up to now each has worked in isolation. Due to recent procurement problems and other issues, the company would like to connect all sites to a network so that ordering of raw materials, distribution and reporting becomes easier. In particular the network should support:
▪ Inter centre communications ▪ Communications to all headquarters with sufficient mechanisms for large file data transfer. ▪ Access to the Internet (Telnet, FTP, HTTP) ▪ Facilities for remote interrogation of databases at remote sites ▪ Web Server and email systems ▪ Appropriate bandwidth and servers for streaming video, audio, etc ▪ Other applications necessary to deliver disaster relief
In each section of this report I will detail the methods and technologies chosen to support the above requirements. I will
