Hello All,
There were some queries about the idea which I hope to answer.
The system of high speed serial data dumping that I wrote about will not replace the existing internet. It will only provide an extra ultra high speed channel for downloading heavy files for each one and everyone without the bother of bandwidth sharing and at a very affordable price. As a rule or plan, all files above 5 or 10 Mb can be considered eligible for this system. Entire web sites can be downloaded as a single arcihve file. The ones lower than that, can be downloaded using the normal internet. All peer-peer, VPN, chat, email, online registration, payments, shopping etc. will be done using *regular internet only*.
This high speed channel will not only be usefull as an infotainment channel for music, news and video but also for normal software and other heavy file downloads.
Suppose you need to download 4 CDs of Linux, totalling 4 x 700 Mb = 2800 Mb or 2.8 Gb in your home. Even at a speed of 512 Kbits per second, your speed in bytes will be 512 / 8 = 64 Kbytes per second. So 2800 Mb will take (2,800,000 Kb / 64) seconds = 43750 seconds. This translates to more than 12 Hours. So it takes approx. 3 hours per CD to download even at 512 Kbps which everyone still cannot afford yet or their locality does not have this facility. You also got to treat your cablewala as God.
Instead of that, in the system suggested, the waiting time would be max. half an hour or one hour but 4 CDs would be downloaded in less than 3 seconds. Imagine the time saved for people who need to download CDs regularly and in large numbers. A single DVD of 4.3 Gb would be downloaded in 4.3 seconds. On the regular 512 Kbps it would take 18.66 Hours. All you would need to do is mark all the files to be downloaded from a pilot list and within their rotation cycle of half or one hour, they would all be dowloaded one by one and be ready in your hard disk in one cycle itself. The maximum you can download within this rotation cycle will only be limitted to the maximum capacity of your hdd. The same data would take days or weeks to download under normal net circumstances. 120 Gb takes more than 21 full days to download at 512 Kbps. In this case, half or one hour. Take your pick.
Frankly I don't know what is latency in a satellite but if Philip could elaborate more and provide points on why it has a problem in sat transmission, it would help a lot in making improvements to this system. Since the repeat cycle of data broadcast is every hour or half, problems due to bad weather or earth's rotation will be temporary. Any modifications and suggestions are welcome too.
The example I gave is for a 1 Gbytes per second speed having a capacity of 86.4 Terabytes per rotation cycle of half or one hour. This should suffice for all the heavy files that currently exist everywhere on the internet. If it is technologically possible, we can use much higher speeds like 2 to 5 GBytes per second and that will pack in multiples of 86.4 Terrabytes per cycle or reduce the cycle time for the same amount of data.

Rony.
