    Is 40Mb enough?

    Concurrent user connection is at most about 100.

    Is 40Mb going to provide sufficient enough bandwidth for VLE, MyMaths and other typical usage within the classroom? Onsite email server too.

    Need opinions on this. While 60 through to 100 Mb is option I'm not sure it's *really* needed or gling to be utilised.

    Any school out there running a similar connection for a greater amount of concurrent users without issue?

    Hi, we are very similar and running a 30mb line. We do have awoke qos on the firewall. This allows the staff to take priority and then the students, we do slow the connection for students streaming videos etc.

    Yes, everything is fine. We use to experience some problems until the qos. We discovered the students were using all the bandwidth on hd YouTube videos.

    I am currently doing a Layer 3 Cross Forest migration internally due to the merge of our 2 schools joining next door to each other. Have installed a fibre link between the 2 sites to avoid the need of county involvement. We hit out 40 meg limit regularly. Once the networks are joined our feed is to be uncapped up to 100meg to support the additional users going through our internet.

    Originally they were going to Bond the 2 x 40meg connections but are now apparently going to uncap the line.

    Teklogic - Is that QOS on the county firewall or are you using QOS on internal switches?

    how many client machines do you have? my last place with 900 desktop clients would sit at around 40-50meg all day.

    100mb should be fine for that! I also used to run all the schools phone lines over our leased line which saved about 3k a year!

    I have a lightspeed rocket server working as a bridge to and from the leased line, all the qos is carried out as part of the content filtering.

    What region are you in?
    We are behind county Netsweeper filtering.

    Norfolk, we have stopped the county connection in favour of our own solution.

    We also dumped our lea's offering and went with our own line and a smoothwall. You need Smoothtraffic for QOS features I believe although you might be able to do user qos in the web proxy settings.

    We have 40mbit with EMBC currently and we barely touch it tbh. We host all our own services. Moving to a different supplier with 50mbit but with prices are they are atm, should finances not have been quite as bad we'd have probably gone for 100 to keep things nice and futureproof but with a 100mbit bearer anyway the upgrade is a cinch. If anyone actually uses 40/50MB without having a remote site to care for (we do but its close by and have a separate gig link to it) I'd be interested to know what for. Only big use I could see is remote or, ugh, "cloud" backup systems.

    We host all our own services which include:

    e-mail
    Remote access
    Website
    VLE
    Run Youtube througout

    350 clients and over the past 4 years have never been above 6mb so we run 10mb on a 100mb bearer for future proofing.

    We don't have voip as yet, all our phones are still analog but looking to go down the soft phone option in the near future, this may mean an increase in bandwith but will measure this beforehand.

    I would think 40mb is fine for what you require.

    We had 100Mb, was a total waste. Stats showed we were maxing near 20Mb but we went to 40Mb for safety.

    That's for 2 Schools one with ~1000 users other ~500. 800Devs one site 500 on the other.


    If the users are all downlaoding ISO's , DVD's Rips, Torrents and other junk then sure 100Mb will be needed. If you have good filtering, a decent cache and other security then the above should not be comming in.
