HI, I am new to tc. I have a few basic doubts about the working of tc.I am trying to limit the bandwidth between two linux machines to 12Mbps. I am using the route filter to achieve this. I tested with ttcp traffic between these machines. I used tcpdump cature the data during this transfer and observed this using tcptrace. I find that the throuhgput was much higher than 12Mbp sometimes during the transfer. But the avg throughput for the whole transfer was 12Mbps. NOw my doubt is how tc is going to limit the bandwidth?? Please let me know how exactly tc limits the bandwidth. thanks mahesh _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com
