Problems Coordination

Prof. JT Lee and I are not the person concerned. So, we cannot decide something.

DVTS Performance Long RTT of PNU<->KSU: 70ms

PNU has own AS. So, we have to modify routing configuration.

RTT became 10ms Bandwidth: 7Mbps

Feb. 27, 2003 Middle School Project 9

Cause of Bandwidth problem

Feb. 27, 2003 Middle School Project 10
