Abstract

The invention provides an address allocation method and system of a dynamic host configuration protocol (DHCP) as well as a client side and servers of the same. The method comprises the following steps: after receiving a DHCP discovery message sent by the DHCP client side, a first DHCP server encapsulates addresses of routed ports of all the DHCP servers receiving the DHCP discovery messages in a network in a DHCP response message, and then sends the DHCP response message to the DHCP client side; the DHCP client side sends DHCP request messages to the DHCP servers according to the addresses of the routed ports of the DHCP servers in the DHCP response message; and according to a DHCP confirmation message returned by a second DHCP server among the DHCP servers, the DHCP client side determines to be allocated with address information. By utilizing the technical proposal, in the event that the DHCP servers are in a hot backup environment, the IP address acquisition rate of the DHCP client side is improved, and allocation efficiency of the IP addresses is improved.

Description

technical field

[0001] The invention relates to network communication technology, in particular to a dynamic host configuration protocol address allocation method, system, client and server. Background technique

[0002] Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol; referred to as: DHCP) is an operating mechanism that uses a client and a server, and is a transmission control protocol that simplifies the management of host Internet Protocol (Internet Protocol; referred to as: IP) address configuration. / Internet Internet Protocol (Transmission Control Protocol / Internet Protocol; abbreviated as: TCP / IP) standard. The process of assigning an address by DHCP mainly includes: the DHCP client sends a DHCP discovery (Discover) message to the DHCP server to apply for an IP address; the DHCP server assigns an IP address to the DHCP client. Among them, when the DHCP client and the DHCP server are in the same local area network, the DHCP client directly sen...
