2x ADSL Lines

hilton said:
Yes and no.

Technically no, as this is just load balancing, but yes because when you're doing a lot of downloads, some will come via WAN1 and others via WAN2 so in effect it's 8Mb but not in the real sense.

Do you follow all that? :-)

im looking for something that even if im downloading 1 file it will give full speeds

Ah the Holy Grail!

Not in this country by default. Or should I say not with standard DSL. You could of course order 1 x 8Mb diginet line from Telkom.................

Remember of course, 4mb or 8mb on DSL is still subject to the local contention ratios so perhaps you'll never get that. What's the need to download at this speed? Telkom is going to change all 4Mb lines to 8Mb lines soon so maybe your wish will be granted.

yes but when they upgrade speeds il have 16mb:D

You get backup lines (ie uses ADSL if available else uses dialup), then you get load balancing that allows you to utilise the max of several lines. But instead of only using the next line if the first is full, it divides the packets amongst the lines.

so if a download 1 file from megaupload or any other normal download will i get 4mb speed or 8mb speed? im talking about a single file
 
Not to dampen you spirits because this dual line idea sounds great but remember two lines with Telkom may mean twice the hassle we all normally have with one line.
 
Theoretically it is possible. But in practise it obviously doesn't happen. If you have 2x 4mb lines (input into a load balancing router) you have a theoretical 8mb line of which you can use ~83% of the capacity ->6.64mbps -> 0.83megabytes per second (or 850kilobytes per second). This is the maximum you will be able to achieve.

yes but will i get that speed on a single file or do i have to do multiple downloads?
 
On whatever you want. Your "adsl connection" will then run at approximately that speed. You should still remember that this all depends on the quality of your adsl line, the distance to the adsl exchange and then obviously the downlink speed from the website, etc. But this is at best case scenario.

yup i get that part , telkom is doing adsl installations fast from the posts of other members but how long would they take for this whole thing to be installed:sick:

Very much depends on the load balancing algorithm & client software used.

For instance if the router identifies individual sessions (eligable of balancing) as unique source/destination IP/port pairs and you're using multi-threaded software, a single PC could max both/all lines with a single transfer/download.

Examples would be downloading with a multi-threaded download manager (e.g. FDM) or accessing a news server that allows multiple connections etc. Even normal browsing (of a single page) should be snappier as it is inherently multi-threaded e.g. body, frames, images, videos, applets etc. can be transfered in parallel.
 
Anything from 5 days to 5 months, depending on what the technician feels like. After the adsl line is done it all depends on how fast you can plug in the router and configure your settings.

so it all depends on the setup? hi can you recomend a router for about R1500 , froot please give me your recomendations also please , it would be appreciated

Your best bet is to try and find a reconditioned 837 (think ~ R 2500), but that will only do 2 lines (internal ADSL + cheap external ADSL modem on one Ethernet port).

Next step up would be the 877 Adv IP ( ~ R4500+) which could do 4 lines ( 1 internal modem + 3 external cheap ADSL modems on Ethernet ports ).
