I am very interested in how things work "behind the scenes". Corporate networks, websites, information systems, and ISPs are all things I have respect for; to learn how they tick inside and to take away their mystery have been my motivation in creating a computer network at home. Below are the details of my implementation. Things are fairly stable now and some of my adminsitrative duties are automated. My three main educational goals are:
Internet connectivity to the network is via ADSL. I am using Direct Network Access, Inc. for IP connectivity, and PacBell for the DSL circuit. On my end is an Alcatel DSL bridge unit. The circuit tops out around 40 kilobytes per second. Average latency from my end to DNAI's end over the circuit is around 25 miliseconds round trip.
There are two local access networks (LANs) in my home. Connecting the two networks together is a dual-homed gateway, a Pentium-class computer running Solaris. The host acts as a firewall/router.
