clock rate and bandwidth question

Hi. I just wish to ask the difference between clockrate and bandwidth. I mean if i have a line provider of 1024 then my bandwidth is declared as 1024 in my router interface but does that mean that my clock rate is also 1024?

Thanks in advance.

Hi friend,

This info may be helpful for you:

Interface and Hardware commands (check for bandwidth and clock rate):

Clarifying bandwidth:

Bandwidth vs clock rate:

Re: clock rate and bandwidth question

From the second referenced link, "However, TCP will also adjust its initial retransmission parameters based on the bandwidth configured on the interface.", anyone know any more about this? I don't see this as even possible except if the Cisco IOS device is either the TCP source or destination. Even then, doesn't seem to comply with RFC2988, if true.

In the third reference, there's ""Clock Rate" is the physical rate, at which data are transmitted. It's your actual speed.", yet my understanding has been the clock rate, depending on the technology, is not always 1:1 synonymous with bit rate although it is some ratio of your physical speed.
