Hello when hosting company offer dedicated server at 100 Mbps port, and they said you can expect 35TB inbound and 10TB outbound what does inbound and outbound mean ? some body please explain this thanks
outbound is the data to the visitor e.g. a web page or file download. inbound is the data from the visitor e.g. the text sent for a forum post. Generally a web server uses more outbound data then inbound.
I think you had this question due to unmetered bandwidth offered with the dedicated servers. Some of the hosting providers offer limited bandwidth with the dedicated servers with 100 MBPS port but do not have a limit on outbound and inbound data transfer and hence you can consider this type of hosting providers for dedicated server hosting.
Unmetered Method: The second bandwidth measurement is unmetered service where providers cap or control the “top line†speed for a server. Top line speed in unmetered bandwidth is the total Mbit/s allocated to the server and configured on the switch level. For example, if you purchase 10 Mbit/s unmetered bandwidth, the top line speed would be 10 Mbit/s. 10 Mbit/s would result in the provider controlling the speed transfers take place while providing the ability for the dedicated server owner to not be charged with bandwidth overages. Unmetered bandwidth services usually incur an additional charge.
100mbits line = 100mbits/s so in a month you get : 100*1024*60*60*24*30 [no. of bits] * [sec->min] * [min->hour] * [hour->day] * [day->month] = 265420800000 bits/month = approx. 32 TB/month [8 bits = 1 byte] if your host guaranteed more that 32TB/month you may need to check the calculations with him. This is how i have been calculating for a while but if i have made any mistakes please correct me.
10mbps is 3300GB a month 100mbps is around 32000GB and when you buying dedicated server do you prefer the unmetered bandwidth or the dedicated bandwidth ?
Depends on what you are going to use it for. If you need very high speeds for short periods of time then use dedicated 100mbits. If your bandwidth will be evenly spready out then go for unmetered. Keep in mind the number of users and lowering it from 100mbits to 10mbits will make a considerable impact. Also most hosts allow you to get excess bandwidth for a small amount but upgrading from 10mbits to 100mbits may not be instantaneous. For example if your having a video sharing site with users who generally tend to come in large numbers at say 6 - 10pm everyday then you may want to use a 100mbits. If for the same site you get an evenly spread out traffic with average users at all times then a 10mbits unmetered might be a better option.
