For pool mining:
Say your hashrate is 567MHash and that uses 12kb/s.
Divide by 567, times by 1000, that gives you 1GHash
Now you do the same to your bandwidth.
12 divide by 567, times by 1000.
Equals 21kb/s per ghash.
Replace 12 and 567 in all instances with your bandwidth and hashrate.
if i use your calculation it s showing 21 meg/terahash
so means for 10 tera you need 210 meg?
am i correct?
Keep in mind that this traffic you are talking about (between the miner and the pool server) does not go out on the internet for typical solo mining setups. Why? Because you typically have your miner(s), pool server and bitcoind all on the same local area network. The only thing that goes out on the internet is your bitcoind network traffc. All the stratum / GBT stuff happens on the local network.
ok let s sum up
let s say i have 10 rig of 1 tera each.
let s say i have one sever where my bitcoin d is located .
with 1 rj45 going from my hub to the 10 mini rig i will be able to make all this works right?
but how much my server will need as bw ? 21 meg or 210 meg?
In solo mining where everything is local there are 3 types of network traffic:
1) Traffic between miner(s) and pool server (stratum/GBT/getwork on LAN)
2) Traffic between pool server and bitcoind (none if both are on the same server)
3) Traffic between bitcoind and internet
Your initial post asked about internet traffic requirements (item 3)).
The answer to your example is 210 meg on the LAN, but this is talking about item 1). It does has nothing to do with internet connection speed.
Unless you are solving all the blocks on the network the internet traffic used by bitcoind has little to do with the hashrate of your solomining setup.
so if i m right
the internet bandwith will be ridiculously low comparing to the hashpower in this type of setup,right
even 1 mbps/sec would be enough
but now complementary question
how to setup own stratum or gbt (what is gbt btw)?
i ve read some info on setting stratum pool on shush website so that basically install the software and tweak the setting and all is on?
it s seems too simple
am i missing something here?
