About half our bandwith is currently satellite and has been for years. We use it directly to home customers, small (64kb-2Mb) wholesale customers and for our own pops (over 45Mb). Latency - 95% of customers never do anything interactive, satellite is useless for gamers but for ssh and the like it just feels like a dialup (which I'm using now and which "pauses" for a couple of seconds every now and then) TCP Windows - We show home customers how to adjust these but don't bother for any of our hardware. Thats about it, the whole thing isn't rocket science, packets go from A to B and take a bit longer to get their. You have asymetric routing but the only problems that happen is that US NOC admins run around screaming when you tell them about it. Here is how we used to do it: interface Hssi1/1/1 description Newtec modulator: PAS8:20K, XXXMbps, 12.575GHz, xxxMSym, FECx/x no ip address no ip directed-broadcast encapsulation frame-relay ip route-cache flow no ip route-cache distributed no ip mroute-cache no keepalive ! interface Hssi1/1/1.1 point-to-point description PVC to TIG-AUS-SYD-1.IHUG.NET ip address 203.109.xx.xx 255.255.255.252 no ip directed-broadcast no ip mroute-cache frame-relay interface-dlci 20 CISCO ! and the same soft of thing in the other end. We have changed everything to PC-based transmitters and receivers however. A live sat-routed ip you can ping is 203.109.203.107 . Please don't flood it or anything though. The return is via ground bandwidth, a comparison ground routed ip on the same network is 203.98.23.114, please don't abuse this either. -- Simon Lyall. | Newsmaster | Work: [email protected] Senior Network/System Admin | Postmaster | Home: [email protected] ihug, Auckland, NZ | Asst Doorman | Web: http://www.darkmere.gen.nz
