摘　　要：在DHCP协议运行的过程中引入心跳机制,从心跳包的设计、心跳机制的触停机制、"休克期"的设定方面做了尝试,在无可分配IP地址时,强制释放用户列表中因连接中断等原因造成的活跃度较低但租赁期限未到的客户端IP资源,实现有限IP地址资源的合理分配使用,并尽量减少心跳包占用的系统负载及网络带宽。Through the introduction of heartbeat mechanism in DHCP protocol application system, some attempts are made from three aspects of design heartbeat packet, operating the heartbeat mechanism and setting-up ＂shock stage＂ on heartbeat mechanism. In the absence of assignable IP address, it forced release 1P addresses in the user list which are in low active degree but in lease term due to connection interruption to realize equitable distribution of finite IP. And it tries to lessen system load and network bandwidth occupied by heartbeat packet.
