Chapter 7 Performance Statistics 91
The third period is a selection period when the DHCP
workstation selects the IP address offered by one DHCP server.
If multiple DHCP servers send “dhcp offer” messages to the
DHCP workstation, the DHCP workstation will accept only the
first received “dhcp offer” message, and broadcast one “dhcp
request” message as response, which includes the selected
DHCP server request IP address. The workstation broadcasts
the “dhcp request” message in order to inform all DHCP servers
that it has selected the IP address offered by one DHCP server.
The fourth period is an acknowledge period when the DHCP
server acknowledges the offered IP address. When the DHCP
server receives the “dhcp request” message responded by the
DHCP workstation, it will send the DHCP workstation a “dhcp
ack” message which includes the offered IP address and other
configurations, informing the DHCP workstation to use the
offered IP address. The DHCP workstation will then bind the
TCP/IP protocol to the network card. All other DHCP servers
except the selected server will take back their offered IP
addresses.
