Telnet Bandwidth

how much bandwidth is used in a telnet session?

Re: Telnet Bandwidth

how fast can you type ?

Basically, each character you type is 1 byte.

This will be encapsulated in a TCP packet and sent to the other side.

With some special algorithm like naggle, this behavior is slightly changed but the idea is the same. 1 chacter = 1 byte.

So, if you can type 1000 character per second you will consume a little bit more than 1 kbyte.

Re: Telnet Bandwidth

I hate to be pedantic about this but since the TCP and IP headers take up about 40 bytes + the layer 2 header will take up another 10/20 bytes then for each character about 50 bytes will be sent. Thus typing at 1000 bytes/second you would consume about 50KB no 1KB.

Re: Telnet Bandwidth

Thank you for your input. The real reason I asked was because a customer is having a problem with an application that apparently runs on a telnet session over a 2mb ATM WAN link. We were trying to get an idea of the bandwidth consuption, and I see there are several variables involved.

Thank you again.
