The book, though, is © 2004!! I was thinking I'd eventually do a review of the book for this site. Hmm. Guess I've got at least one negative comment to make. Now I don't know whether to keep reading.WayneW said:I think your information source is old. AFAIK, bus Ethernet went out with the coax, I think it was called 10base-2 and it was daisy chained.
The other key word is "hub". For anything with more than a few ports, I don't think hubs are easily available anymore. Everything big should be on a switch, which only sends traffic down the leg it needs to go. It doesn't broadcast to all legs like a hub did.
Ater I made my post, I spoke with the best computer-engineer I know (EE and Comp Sci; background in process control) and he said the same: star topology is better, now, than bus. Intelligent switches replaced hubs some time ago and the switches handle routing to as to reduce traffic. Bus systems, he said, "were suseptible to 'chatter' which can bring the network to its knees".
Anyway, one good thing to come from all this is that he's agreed to take a look at my cabling and he supposedly has some $8k piece of equipment that can detect even slight degradation of performance caused by things even as slight as (to use his words) "the pressure of a chair on a cable". (I think he's going to find a lot worse problems with my wiring than that!) He's not a HA expert but he does know computer networking.
I asked him about gigabit ethernet and he's going to look into pricing for me. For streaming HDTV, at least, I'd think this might be a good upgrade to plan.
