how exactly does a router share the internet


Recommended Posts

ok i am going to get a 4port broadband router next week, but i want to know how does it share the connection equally.

i will have a 1mb connection shared between 2 computers,

i currently have a 300k connection on 1 computer.

with my currnt setup i often get problems with the internet say if i was running emule in the background (only downloading at about 15kb/s) then when i go on a website it's compleatly screwed and takes agerz.

will i have the same troubles say if i was running emule on one PC and browsing the net on the other?

yes you will.

and problem is not becuase you share internet, but becuase your emule is taking up all your available upload bandwidth, which cuases webpage request traffic to be queued up with emule upload traffic.

if you cap your emule 2-3k/s below your maximum upload capacity you won't have this problem.

i have a 4-port Netgear RT314 Router.... great thing

routers share the internet-bandwidth as needed... and as available

everyone get equal... ive looked for a router which you can limit bandwidth on specific IP's... lol... have to share with my sister and she often forgets to turn off kazaa

well... HOW exaxtly it does it, cant tell ya... its called: NAT - Network Address Translation, which if im correct lets your LAN seem as 1 "ONE" computer/IP/MAC address, but you still have a fully functional network

also... when getting a router, get used to not being able to done certain things... because of the NAT, you will have to forward certain ports that you want to be open to the internet to your computers IP

example:

you want to open a Quake 3 server...

you would have to forward port-range 27959 - 27961 (new quake3 port: 27960) to your network-ip

in order for your server to be seen and accessable from the internet, however, the server will not be available over the network, as the specific forwarded port will now only be visable to the internet....

youll notice and learn how/when to use as you need...

deffinetly 4 port switch :) whats the diff between a switch and a hub?

...you wont really notice a difference between 100mbit switches & hubs...

its when you have a 10mbit hub, and theres lots of traffic it starts to stutter...

basicly a switch can transfer data faster from one port to another while there is also other traffic to and from other ports

imagen it like this:

the switch has every port connected to every other port, while the hub has all ports on one rail...

someone correct me if im wrong... :ninja:

I think the difference between a switch and a hub is that a switch has seperate network bandwidth for each node, where the hub has one lot of bandwidth for all connected nodes.

For home users I see no point in paying a little more for a switch seeing as it only speeds up concurrent transfers of very large files... maybe if you have computers transferring mass amounts of data constantly it would help... but i've got a 8-port hub and it works fine for me. Switches reduce packet collision but increase latency.

I have an RT314 too, it r0x0rz ;) .

A switch is better than a hub, because a hub only splits the bandwidth. That means, on a 10mbit lan, with a 10 port hub, each pc would get only 1 mbit transfer. A switch does not do that, it just lets everyone loose . :devil:

i have found out about port forwarding ect, and it looks simple enough, the router i am gettin is uPnP so i shouldn'd have to mess about with ports for MSN :)

a switch prolly isn't worth the extra cash for the home user, but for ?50 inc vat and p&p from amazon ain't bad:DD

Well I have 512kb ADSL, and I have 100mbit ethernet cards, cables and hub. Noones loosing out because noone can get more than 512kbits out of the Internet anyway.

I don't transfer gigs of data between computers constantly, and hubs have less latency than a switch.

I'll stick with a hub for now...

darkness2k..... i have FastPath turned on at my ISP for my 768/128 aDSL over my RT314 Router... and i ping around 7-30ms in any game

so i doubt the slightly higher internal latency of a switch is a downside

hmm, whats that uPNP?? MSN and a lot of programs use random-ports, and thats the problem, you cant allways forward ALL ports to your computer which would basicly bypass all the built-in security features

how does the program know what computer YOUR computer has open and which is going to be accesses via the internet?

could be some kind of port-scanning proggie built into the router... cool

...oh and by the way my home network:

my comp -> 100mbit HUB -> 100mbit Switched Router -> DSL-Modem -> Spliter -> wall

a 7ms ping to an internet game server is pretty good... id say :D

uPnP is a microsoft feature that allows MSN messenger to work properly with out forwarding ports for it, i think it only works on Me, 2000, and XP

oooohhhh nice :D

is it a windows service?? if yes, then i have it turned off.... hmm, sucks

then again... i use Trillian and forward ports i need, hehe

yup it's a windows service, it's switched on in WinXP but you have to manually enable it in SP1, but i'm not sure about win2000 and Me

Yes that is good..... I'm used to ping rates of between 100-250 depending on network conditions etc occaisionally I get the odd game thats at 53 or so... but thats usually if noone else is in the game lol
