P2P limiting, or Not? Possible strategy

Wed Jan 23, 2008 2:19 am

I see many posts on this forum users struggling or advising on P2P blocking, limiting or allowing.
I see mangle, queiing, traffic limiting, the new L7 protocol etc. etc.

What I never see it the following approach:

In an all MT operated network (Clients and AP's) and when sufficient bandwidth (2 x 8Mb + 1 x3Mb ADSL) to the Internet is possible and 50 to 100/150 users my strategy is as follows:

All clients CPE´s are upload and download speed limited by the AP (works only for MT clients) and all my clients have 3Mb (or less) download and 256kb up.
All traffic comes to main MT router which has load balancing with fail over to the the present 3 ADSL lines.

In the firewall filter of each MT-CPE I block all P2P traffic upload. (from client to other peers)
P2P traffic download is blocked per default too, but clients that wish can have the downloads allowed, I will monitor and as long as total download traffic stays withing ´fair-use´ policy, there is no problem.
Their maximum download speed is 3Mb but they hamper their own other services if they use it all for P2P. (I inform them, but its their problem, users normally know how to work with their software.) and for the total network saturation is something I still hardly see happening.

I think this is a simple approach that might help lots of readers out.... or not?
Or am I too simple?
Anybody any comments, remarks or critics?

i'm sure that i missed something, because if i do the math...50/150 users downloading at 3Mb....that's won't work
am i wrong?

Have you ever seen all users using the capacity to the full at the same time?
In general you sell your bandwith multiple times.

If you have 8Mb to sell and you work with a ratio of 1 to 20 (normal) and each client gets 3Mb then you can actually have 53 clients. (8 x 20 = 160 / 3 = 53)

You must see your network as a 4 lane motorway leading to a big town (the internet). Commuters from 5 nearby villages have each two lane supply roads connecting their village to that motorway.
If they now decide all to go to town at the same time and start filling the 2 way supply roads you will see congestion on the 4 Lane motorway leading to town.
But if these commuters all spread their time to go to town we have no problem. At times one or two supply roads might even user their full capacity but as long as not all villages do this regurlarly at the same time everything is fine.

the bigger your network and the more capacity, the higher you can set your ratio. Big networks have more internal spare capacity then small ones. Off course its also important how you deal with the expenses (capacity cost money) versus the income (users bring in money). If you set your ratio to high, you´ll see too many complaints from users and clients run away!

So, available bandwith is not the same as consumed bandwith.

I'd sue an ISP if they'd block peer2peer.

And anyway... there are always tunnels and traffic encryption to go pass your filters... so why bother?

Who owns the network? I thought the provider. So, within the limits he decides, not the client!
If I want, my network is for mails only.... I´m the boss!!!!

And anyway... there are always tunnels and traffic encryption to go pass your filters... so why bother?
And there will be always one smart enough to rob the bank of England. That doesn't mean all security and client regulation should be left behind?
I have over 60 clients now and still growing. Clients have had no problems with my policy so far. Within limits P2P can be used and so far and if because of this am providing the cheapest, fastest and most reliable network in the region.

If you post such comments on this forum think before you make your statement. Every policy can have its arguments....

As a customer you buy a ´service´ according the conditions the provider sets....
No provider in the world allows you to use your asssigned bandwith for full 24/7 and no provider allows you to abuse their network for spam or other malicious use.

In other words, you buy a product like it is prescribed in the product license/regulation. Nothing more, nothing less.

Not in other countries. Here I personally pay for 2Mbit guaranteed internet connection witout restrictions, it's entirely up to me what I do with it, and it's entirely up to the ISP to make sure others get what they pay for without interrupting my guaranteed 2Mbit service.
