    Broadband Speed and # of Computers

    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

    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

    1Gbit.
    Fibre w/CLEO LLU.
    No contention.
    450 Machines.
    CLEO.

    Limiting factor is the LancsNGFL proxy servers.

    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.

    [QUOTEType of service[/QUOTE]

    ADSL

    [QUOTE]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

    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.

    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!

    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

    Yes, it is slow at times

    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.

    Standard install for CLEO in a secondary school. Cost is about £1200 + £3 per pupil I think.
