ictstbenedicts Posted October 10, 2008 Posted October 10, 2008 We currently have a 2Mbit SDSL connection with a very low contention ratio, supplied by Easynet. I'm getting complaints that it is at times slow. We have about 400 PCs on the network at any one time during the school day of which a certain percentage will be using the internet. I would be interested to discover what other schools have regards broadband connection in particular: Speed (Mbits per second): Type of service e.g SDSL, ADSL, Ethernet, Leased Line etc: Contention ratio of that service: Number of Computers on the network during the school day: Name of ISP: Thanks Mark
kmount Posted October 10, 2008 Posted October 10, 2008 10mbit both ways. Leased Line 5:1 (mind you, we don't notice any contention) 550 ish. EMBC
cromertech Posted October 10, 2008 Posted October 10, 2008 8Mbit connection both ways on a 5:1 contention Sometimes slow but always due to a rubbish cache pilot that I am assured is "working normally" around 300 pc's at capacity
Geoff Posted October 10, 2008 Posted October 10, 2008 1Gbit. Fibre w/CLEO LLU. No contention. 450 Machines. CLEO. Limiting factor is the LancsNGFL proxy servers.
RabbieBurns Posted October 10, 2008 Posted October 10, 2008 8mbit normal adsl 800k upstream. 400 machines. No problems.
maniac Posted October 10, 2008 Posted October 10, 2008 10MBs Fibre (Both ways) from KCN (SEGFL) Around 500 machines Works well most of the time, but they've been experiencing some problems recently which slowed things right down. KCN are just upgrading their setup to support speeds of up to 100MBs and beyond so the future's looking good. No idea if we have any contention ratio on the KCN setup. Most schools in Kent will have the same, although at varying speeds depending on what the school has payed for. 10mbs is the lowest offering, and I don't see the need to up this at the moment, but the introduction of a proper VLE may change this. Mike.
dhicks Posted October 10, 2008 Posted October 10, 2008 Speed (Mbits per second) 512 kbits / second. ADSL Contention ratio of that service/QUOTE] Depends on time of day. 50-ish to 1? Number of Computers on the network during the school day 150 odd. Name of ISPp BT. I think. -- David Hicks
localzuk Posted October 10, 2008 Posted October 10, 2008 We've got a 10mbit fibre, with 250 pc's with an average of 140 using the internet at one time. I've seen it at 80% usage during that sort of time.
FragglePete Posted October 10, 2008 Posted October 10, 2008 SWGfL 10Mbps both ways fibre into the School 2:1 Contention Approx 400 PCs Have had the odd occasion where the Grid seems to slow. Upgrade to the Grid's backbone is happening this November. Currently Children Services at Swindon LEA are looking to providing a Point-2-Point WiMax Server for Schools; surveys are being done at the moment. This is supposed to give 100Mbps with the existing 10Mbps kept as a backup! Pete
amfony Posted October 13, 2008 Posted October 13, 2008 4 MB symetrical across 300 nodes @Geoff - I cant believe a school can afford 1 GB internet access! Thats just purley and utterly bananas. Do you work for eaton? haha
Nick_Parker Posted October 13, 2008 Posted October 13, 2008 We have a 4MB account which has a 50GB monthly limit on it, after hitting the limit, internet throttles down to 128KB... Oh, and about 230 computers
localzuk Posted October 13, 2008 Posted October 13, 2008 4 MB symetrical across 300 nodes @Geoff - I cant believe a school can afford 1 GB internet access! Thats just purley and utterly bananas. Do you work for eaton? haha From what I know, lots CLEO secondary schools have 1GB access.
pmassingham Posted October 13, 2008 Posted October 13, 2008 Essex LEA is the 'provider' over Siemans/Updata Up to 8 Mbps over copper 5:1 contention 670 clients of which about 50% usage per day But more importantly - up time up to 99% over the last year. Plans are in place for a major improvement within 12 months. Some of the 'slow' speed is LAN related as there is contention there given the amount of data usage.

Do you work for eaton? haha Standard install for CLEO in a secondary school. Cost is about £1200 + £3 per pupil I think.
amfony Posted October 13, 2008 Posted October 13, 2008 sorry dudes you lost me at CLEO - whats that? 1GB though ... how do i draw a jealous smiley? i dont know how haha so ill draw this To be honest though ive never even heard of a "school" (as in k-12 institue), the largest bandwidth requirements ive heard of was 10MB Symmetrical for a College that provided very significant (as in end users) online correspondance schooling. What do you do (any one with this type of bandwidth) with this type of connectivity?? Or is it more of an celiing limit that you'll never hit type deal?
Geoff Posted October 13, 2008 Posted October 13, 2008 sorry dudes you lost me at CLEO - whats that? CLEO - Cumbria and Lancashire Education Online http://www.cleo.net.uk/index.php?category_id=113
amfony Posted October 13, 2008 Posted October 13, 2008 (edited) double post - i thought my post wasnt posted for some reason? Edited October 13, 2008 by amfony being simple
gaz350 Posted October 13, 2008 Posted October 13, 2008 24down/3up bonded ADSL. Provided by Vioni. 400+ computers on our network (not counting iphones, ipod touchs etc) Only since allowing access to video has our bandwidth got any where near to being saturated (lunch times) as our filtering box on site cannot filter webpages fast enough to get bandwidth up to that level just from normal surfing alone. we are looking at moving from a 8meg bonded solution using BT's network over to O2 on be's network and bonding 20down/2up lines instead(80d/8u). sadly were out in the sticks so cant have any of this funky fibre stuff.
ChrisP Posted October 13, 2008 Posted October 13, 2008 ICT Solutions have just sent BT down to do a site survey here (Norwich) looks like were going 100mbit in 2009
Sirbendy Posted October 13, 2008 Posted October 13, 2008 IIRC, we're 100 now, going gigabit soon..LEA provided. The entire town (Telford) is carpeted with Cable courtesy of Blueyonder, and we run on that infrastructure. As to PCs on it..numbers in the thousands with all the schools and public buildings. Not counting IP Phones. 200ish PCs here, plus..ooh..say 50 IP phones. Every public building (again) has IP phones as well, so it's effectively free to call school to school/council. It goes, not to put too fine a point on it, like the proverbial off a teflon coated shovel.
