So this is a turn around from my now usual ranting about dating…
Last Friday, we were in the northern quarter and some how got around to talking about networking. I mentioned I had 3 gigabit switches and everyone asked why the heck have you got 3 gigabit switches? To which I tried to explain, very badly. So I promised to do a diagram of why I need those switches and not just extra long cables.
First thing is the rooms are serial not exactly how you see them above. Aka the bedroom is as far away from the living room as possible and the spare room is in the middle of them both. Ok maybe I should consider redrawing them… The ADSL2 line works best off the main socket in the cupboard (Its how I can achieve my 1.5meg upload consistently rather that 1meg upload). The next room with power is the spare bedroom, where the ADSL2+ router lives. The router is only 10/100, so I use it just as a modem but I’ve recently been turning on the 54G wireless and using it for guest connections. Turns out at the time it was very difficult to get a ADSL router with gigabit wired points, might not be true 2 years later.
The next step into the network is the WRT firmware upgraded Switch complete with 108N wireless. Because its running WRT I can do many things like Quality of Service (QoS), VPN and port knocking for remote access. I class this part the inners of my home network.
Due to the room layouts, I’ve decided to string the network together by putting a gigabit switch in each room. This means I only have to feed one cable room to room rather than 4+. As you can see I have about 4 devices in the bedroom and living room and thats not including a spare one for guests.
So why wired and not wireless? As I live in a set of flats, theres a lot of people with those BT/Sky boxes on random channels (would show how messy it is but you can imagine). The wireless is good but not really for sending full HD videos to my TV without waiting 5 secs for it to buffer and maybe some pauses in the middle. If I switch to wired 100megbit networking, its fine but if I start to do a large transfer over the network, for example if I’m working on some footage on the server at the same time, its noticeably slower and you may get slight pauses. Now I’m certain it might actually be a IO issue with my 54000rpm disks. But I get nothing like this with my gigabit network.
Once I went Gigabit, everything just worked smoothly. I don’t ever see any latency issue, even when streaming stuff to the Xbian in the bedroom at the same time. I once did a test of both my Lenovo XBMC and RaspPI playing Inception at 1080p with me pulling the same file to my laptop. Although the PI struggled playing it back, everything seemed to work as expected. I bought into Gigabit at the point when it just dropped in price. My laptop, Server, Lenovo XBMC box, etc have gigabit ports so it was a no brainier really.
I am keen to try out 802.11AC but right now my main focus is to replace my Lenovo XBMC box which outputs in VGA to the LED screen. This is why I was trying out Simon’s Ouya. I already removed all other desktop machines from the network (got 3 mini desktop machines in the spare room to get rid of).
So thats the crux of why I got 3 gigabit switches…
Feel free to talk about other solutions but they need to be cheapish and not interfere with much else. Its worth pointing out the runs of cables between the rooms are roughly 20meters long. I will at some point drill into the walls but not quite yet. Finally I looked into powerline solutions but there pricey and I’m not sure of how good they are in a set of flats. Think I prefer a ethernet cable, as I would end up with a setup similar to what I have now.
