Branners Posted March 18, 2009 Share Posted March 18, 2009 One for the techies out there. At work we have times when the venues are seriously busy and we can use a 4mb internet connection easily. Normally around September, October and November. the rest of the year we need almost nothing, and some months we can turn off the high speed lines and use ADSL. Anybody know any sort of connection that can cope with that without costing us a fortune? thanks JB Link to comment Share on other sites More sharing options...
caseys Posted March 18, 2009 Share Posted March 18, 2009 You could talk to Virgin and rent cable? I believe you can switch between 4/10/20/50Mb lines. I think most of their infrastructure is capable of all the speeds now but they just attenuate your line. Otherwise BT to rent something bigger? Do you mean 4 megabit or 4 megabyte total? Latency? Upload / Download rates/ratio? Maybe you could rent an OC-1 or OC-3 for those periods off BT or another carrier? Other than OC48s we use dark fibre ourselves Massive initial cost... low maintenance. Massive bandwidth too Link to comment Share on other sites More sharing options...
Ark Posted March 19, 2009 Share Posted March 19, 2009 Doubt many ISPs will cater for that at that bandwidth level, but Easynet give us a 1gb link, capped (and billed) at 85mb burstable - allows us to instantly pump bandwidth for short periods if required, and a trivial change to access more as required for longer periods.

Wez Posted March 19, 2009 Share Posted March 19, 2009 Doubt many ISPs will cater for that at that bandwidth level. The only exception to that is we have 100mb ethernet lines provided by the colo company and we pay for 1, 2, 3 or 10mb bandwidth but the line is not restricted, if we go over what we have purchased then we pay the extra for what is used. This is internal to a colo centre and not sure you would get it between locations from an ISP. You could speak with Level3, easynet and the other big players but it would prob be a costly solution.

JustGav Posted March 19, 2009 Share Posted March 19, 2009 Companies like BT will offer you fractional circuits, which could have a carrier of 34MB, but only allow 2MB(eg) down it. Whether they will allow you scale it up and down depending on time would be a question for the account manager, but given the market I'm sure they would be open to negotiation. Colt did it a few years ago for me, when I had a 34mb installed in our UK office (We had a 34mb bearer but only a 10mb feed) In fact the BT circuits I used years back, where 10mb carriers with a 2mb subcarrier. Branners; What is the traffic profile? There may be another option round the problem which will cost less. Link to comment Share on other sites More sharing options...

Massive bandwidth too Dark fibre rocks but DAMN it is expensive, especially when you have to dig under the M25. DWDM is starting to get rid of the need for dark fibre, About a year ago I had a 10Gb DWDM circuit installed, and boy did BT have some initial issues with it.

Wez Posted March 19, 2009 Share Posted March 19, 2009 We have found that 10mb & 100mb ethernet extentions (LES10 & LES100) have proved very cost effective between our locations, the rental costs are much lower and we just stick them direct into a switch port and create a new VLAN, job done.

caseys Posted March 19, 2009 Share Posted March 19, 2009 Dark fibre rocks but DAMN it is expensive, especially when you have to dig under the M25. We dug up 100kms of the M27/M3 I believe it was costly though. DWDM is starting to get rid of the need for dark fibre, About a year ago I had a 10Gb DWDM circuit installed, and boy did BT have some initial issues with it. Wotcha mean get rid of it? We still use both. We've got 64-channel DWDMs in use and we still want more. Speccing up two OC48s for some IP traffic and we may not thing it'll actually be meaty, but jesus the price difference between 48 and above is astronimical Link to comment Share on other sites More sharing options...
Branners Posted March 19, 2009 Author Share Posted March 19, 2009 If I explain what we do as a business it may put it in to some focus. We have 6 venues in London and 1 in Brum. We have meeting/conference rooms capable of taking from 4 to 300 people. We get a lot of graduate programmes come in where there could be 300 graduates all working from laptops. Naturally that pushes the bandwidth a little. However that is only for about 5 months a year, the rest of the time we could survive with ADSL size of bandwidth. What we want is an internet pipe that we pay £50 for each month, giving us an ADSL type of performance, but we can then turn it up to 10mb for the busy periods and then turn it down again afterwards paying extra while we use that bandwidth. Currently we have 3 x ADSL lines at £45 each per month, and in some cases a WIMAX at 2mb/2mb at £200 per month. That is PER VENUE. We also have 2mb SDSL lines for our own corporate use, plus an 8mb bonded SDSL for head office along with a 2mb SDSL failover. We are a company of around 100 people, but if we fill each venue we could be around 400 people in each venue. So its an interesting proposition.

Pete Posted March 19, 2009 Share Posted March 19, 2009 Sounds cheap John. I've be suggesting leased lines at £5k a year for 10Mb bearers. I could possibly sort out a variable rate charge on bandwidth via a supplier we use, but it won't be cheaper than your current set up for sure. Worst thing is by messing about with configs like this you run more of a risk ending up cut off or with downtime. It's not worth it to save a few bob.

Ark Posted March 20, 2009 Share Posted March 20, 2009 As Pete says, for a customer paying £50 per month, most suppliers really couldn't be arsed to help you out - there's just no margin in it for them... Link to comment Share on other sites More sharing options...
