问几个问题
1.Calculate the bandwidth delay product for the following networks:
SDSL 512Kbps
T1 1.5Mbps
Ethernet 10Mbps
T3 45Mbps
ATM 155Mbps
For these calculations,assume an round trip time of 100milliseconds
2.A TCP machine is sending full windows of 65535 bytes over a 1Gbps channel that has a 10 millisecond one-way delay.What is the maximum throughput achieveable?What is the line efficiency?
3.Give a simple algorithm for finding 2 paths through anetwork from a given source to a given destination that can survive the loss of any communication line (assuming 2 different paths exist).Inthis context,the routers can be considered reliable,so you do not need to take into account the possibility of router crashes.
