Hi,
New here, and to Mikrotik's products.
I shall shortly be setting up a small ISP to cover some rural internet connections in the UK. The service shall be delivered over fibre optics to a potential customer base of 1,600 initially, and then expanding out from there into near by villages bringing the potential customer base to about 4,000 connections.
The penetration ratio remains to be seen, but we've based financial calculations on 25%, so many hundreds of customers. (alternatives provide sub 2Mb/s connections to 6Mb/s, so we're the only game in town that can provide anything faster for the next couple of years, so it could well be higher...)
The services shall be various speed grades up to 50Mb/s initially, but I would like to be able to support 100Mb/s. (both with upload limited to 10Mb/s unless they purchase business products). The backhaul shall be 1Gb/s uncontended Ethernet leased line.
Customers shall be aggregated on a fibre chassis and presented to the Mikrotik on an Ethernet connection as PPPoE sessions. The router shall need to terminate the PPPoE sessions, perform some traffic shaping to prioritize VOIP, Web etc over P2P, and generally make for a good experience. Users shall be authenticated and accounted for using DMA's Radius Manger running on a separate box.
I would like to ask your thoughts on hardware requirements for the core router. I don't think that any current Mikrotik hardware can cut it, so x86 looks to be the way to go. I'm thinking of a single CPU quad core xeon with a small amount of memory. I was also thinking of using SSDs, though I'm not sure how much RouterOS accesses the disk (I was thinking they'd be more reliable than spindles). For the network cards I am thinking of one of the Intel quad port server adapters.
What would you specify if you were looking for something with a little room for expansion (greater penetration ratio or faster speeds)? Cost isn't too much of an issue (digging fibre isn't cheap), but let's not go crazy.
Thanks
