Multicast Architectures
IP multicast allows a server to provide a single source of content simultaneously to multiple receivers. In this last installment of "Networking," Michael Norton explains the magic of multicasting. Aug. 10, 2001

Exploring the Transport Layer
The transport layer of the OSI Network model, Layer 4, is the layer that makes client-server applications a reality. Michael Norton explains how this layer works. Jul. 13, 2001

Net Surfing With IP Protocol
A look at the routed protocol that not only ushered in a new revolution in the 1990s, but also drove the stock market wild -- the IP protocol. Jun. 29, 2001

Understanding Routing Protocols
Do you know your routing protocols: BGP, IGRP, and OSPF? This week Michael Norton explains the various routing protocols and shows you how to configure them. May. 22, 2001

Layer 3 Switching -- Introducing the Router
On the Internet, packets are relayed incrementally, hop by hop (router by router) until they reach their destination. How is this accomplished? Michael Norton explains the router's role in this week's networking column. Apr. 13, 2001

Understanding Spanning Tree Protocol -- the Fundamental Bridging Algorithm
Isn't network redundancy supposed to be a good idea? It is until bandwidth becomes saturated with just a single broadcast request. Mar. 30, 2001

Basics of Network Segmentation: Switching and Bridging
Managing network traffic is easy when just a few computers are online. But networks always grow. Here are a few techniques for handling rapid network growth. Mar. 16, 2001

What Goes on in the Wire
Learn how networked computers find each other using the unicast or broadcast Ethernet frame. Michael Norton also explains the role of the MAC address in this third installment of his networking series. Mar. 2, 2001

The Scholar's Approach to the Internet
The complicated network architecture is much more understandable if we break it into layers and examine the role each layer plays. Michael Norton does just that in the second installment of his networking column. Feb. 9, 2001

Fundamentals of an Internetwork
Michael J. Norton introduces a new series of articles that will cover a broad scope of networking aspects, starting out with basic terminology and then moving on to advanced concepts such as configuring network hardware. Jan. 30, 2001
