Mega-bit+Meag-bite

beomont

Can somebody explain to me how many Mega-bits(say you had a mbit connection)are in a mega-bite.So another words if I had a 1Mbit a sec connection how long would it take to down load a Mbite.And to get the same answer for a 512kbps connection to I just double the time???.I understand you will very rarely get your full bandwidth but am just curious
Cheers

Divide the BIT figure by 8 to get it into bytes. Flat out the 1 Meg service should give you theoretically 125 KBytes/Sec, however in the real world it will max out at about 110-115 Bytes/Sec.

On my 2Meg here, the max I have seen (as recorded by DU-Meter) is just over 230KB/Sec. Of course with net congestion etc YMMV. However I have managed to sustain > 200K/sec downloading the odd linux ISO here & there :-).

if you have a 512Kbps (kiloBITpersecond) you will get aprox 50KBps (kiloBYTEpersecond)... divide bit by 10, that will give you aprox for byte .. if that makes sence

2Meg from Easynet is £119 pcm, paid in full up front for the 12month contract. Installation was £250. It's delivered on ethernet through one of these.

They are about the cheapest in the UK for that speed. I also have a registered /29 with it for that price. As long as you can lie convincingly enough :-) to RIPE, easynet will provide up a /28 with the service.

Here is some sample info . I am using Chorus Powernet 512Kbps MMDS I did a speed check with www.speed411.com and got a calculated speed of 956Kbps I then downloaded Adoibe Acrobat 5 and achieved upwards of 468Kbps and downloaded 8.41Mb in 22 seconds you can see the results here. I am running Simpleserver from AnalogX.com and will leave it running for the day (Chorus get p****d when you run a serverhttp://217.78.4.77

the reason you achive those speeds are because of the bandwidth shaper chorus have on their service.
[ie]the more that use it, the more the speeds are restricted.


Can you beat it sucka??

:)

jbkenn

The purpose of my post was simply to demonstrate what is possible in average daily use with Powernet in a home/office setup . You are achieving incredible d/loads what you got???

that is a picture taken a long time ago to show the speed that can be achieved with satellite access.
it is no longer true.

What parts of the country do they cover ? What are you paying for it ?


Thanks

I am in Limerick AFAIK it is available in Dublin and Cork also

Not bad, for 40 sheets/month one could swallow the installation charge given its a one off. What are your pings like to UK/Ireland gaming servers for example ? What bandwidth figures do they quote for the 3 services ? I assume they packet shape/rate limit on the cable modem depending on service purchased.

It's also a damn fine example of what Eircoms DSL pricing should be. If it was that price this forum would be damn quiet :-).


greg

E-Hub

remember theres no line rental with chorus,

so taking that into account Eircoms adsl is £50 (£90) more expensive,

both have 3gb caps but the price p mb is 2p conpared with eircons 2.6p

the service from what i heard is excellent,

beomont

I got this through email today and regarding the 3gb cap for residential customers I am nerly sure somebody on this board said they had not put it in place yet.By the way notice the nice option below of self install saving you a nice £150 lids

Any poster here should be well capable of doing their own install. :-) Saving a few bob into the bargain :-).

For the high end business bundle, the Zyxel Prestige 312 is a poor choice IMHO . Its a nice piece of kit, but any web connected business may want to run VPN connections from the desktop out to customers/whoever & it doesn't IIRC support any form of IPSEC passthru. The Linksys BEFSR41 would have been a better choice I reckon.

In reply to cmkml I have not tried to ping a gameserver (I dont play games, sorry!) but if you give me some ip's I will try it. for general info it is a snap to install, especially on Win2k, and I will let you know during the week how I get on with a 20 user network as I have to set one up on Monday

Any of the zyxel family are pretty easy to setup. ZyNos is all menu driven & very straight forward. The Web interface is pretty crap. Telnet is usually the only way to do the setup properly. Just make sure you stick some filters on to drop NBT etc on the outbound to be on the safe side.

Yeah, that's what I thought too!!!

Not true.

For some strange, weird and wonderful reason, they won't let you install it yourself. Don't ask me why, but you do get caught for the installation fee. Some technician-type person has to do the install of software.

I haven't taken up PowerNet yet, but it's not for want of trying - they were supposed to send me out a contract last June!

Anyway, when I was talkng to the guy on the phone about it, I mentioned that I could do the installation myself like it suggests on the bumph. "Sorry, no can do" was his reply.

I've subsequently seen posts from people in Limerick on the ILUG mailing list and they confirmed this.

Oh, and btw, Chorus say that Powernet does not support Linux, for those interested.

Are you sure?

I could be wrong but is it not divide by 9 or 10 because of parity bits and other overheads .

The divide by 10 rule applies to modems, where everything is pre/post fixed by a start and a stop bit. For everything else the raw speed of the link is /8. Of course there is then framing/encapsulation over head so the theoretical maximum is never reached. IIRC any error correction happens at layer 2, not in the datastream as with a modem.

Hmm, what a shower, do they force you to purchase their own NIC at inflated prices as well I wonder. What software are they referring to ? Something like WinPOET to do PPPoE ? If so yet another reason to use a dedicated appliance such as a Linksys/Barricade/Whatever to take care of all that & firewall off the connection.

Some cable modem systems restrict access by MAC address. But that problem is easily solved ;-).

They may not 'support' linux. But they would have a hard time stopping one using it ;-).
