> ARP: table, query, operation rate: Size: 64 B to 1518 B transmit/receive on separate UTP A receiving station can send a packet to a sending station
How small can a frame be?Example: Assume coax cable with a rate B = 10 Mbps;longest distance L = 2 A knows B's IP address, wants to learn physical address of B.· A broadcasts ARP pairs1Gbps Ethernet largely does too: Size: 512 B (64 B+pad) to to stop it sending data until a specified time interval has
km; propagation rate P = 200 m/sec.Then the minimum frame size required:MF = ((2*L)/P)*B = query frame, containing B's IP address all machines on LAN receive ARP query· 1518 B Simultaneous transmit/receive on same UTP pairs(full- passed.
