Some Current Switches
|A Brief Survey.
This page presents a variety of the switches available from different
companies. While there are many others I hope this will give you
Linksys has a reputation, at least with me, of providing some of the
best networking equipment for the home or small business user.
They were actually acquired by Cisco, which seemed to me to be an
Linksys is known to have models that combine many different capabilities such as routing, switching and firewall capabilities into a single model. It should make sense that intelligent home users would like to get these sorts of capabilities at reasonable prices.
The following table gives a very brief survey of some of the Linksys switches.

have a reputation for reliability. They are generally considered
to be higher end solutions.

Switches. 3Com places its switches into two main
The way they create their groupings/categories aren't entirely clear to me. For example, some of their workgroup switches really work more to aggregate workgroups on a backbone than to create them. But maybe I'll understand this more later.
The first table outlines 3Com product offerings at the workgroup level. All of the workgroup switches are preceded by the words Superstack 3.
