Title: DYNAMIC HOST CONFIGURATION PROTOCOL RECONNECTION METHOD, DHCP SERVER AND SYSTEM
Abstract:
Disclosed are a dynamic host configuration protocol (DHCP) reconnection method, DHCP server and system. The method comprises: when a terminal switches from a first DHCP server to a second DHCP server, broadcasting outward a first DHCP request message; after the second DHCP server receives the first DHCP request message, and if related device information for maintaining the terminal is determined to be absent, returning a DHCPNAK message to the terminal for instructing the terminal to start a new reconnection. The present invention reduces the time delay caused by repeated attempts of DHCPREQUEST of feedthrough device, thus enabling fast reconnection.
