摘要：
A controller may help reduce network traffic that is associated with broadcasting of Dynamic Host Configuration Protocol (DHCP) packets by converting broadcast DHCP packets into unicast DHCP packets and forwarding the unicast DHCP packets to appropriate DHCP servers. The servers may be identified from a database of servers that is updated with DHCP server address information based on DHCP reply packets that are received by the controller from servers in the network. To convert DHCP request packets into unicast packets, the controller may modify address header fields of the packets such as Ethernet addresses and Internet Protocol (IP) addresses. The controller may forward the modified DHCP request packets to the server by providing packet forwarding rules such as flow table entries to the switches or by forwarding the modified DHCP request packets through the controller.
