Embodiment Construction

[0042] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] see figure 1 , is a schematic diagram of a network architecture applicable to this embodiment of the present invention. As shown in the figure, the network architecture includes a DHCP client, a DHCP server, and a DHCP relay. The DHCP server and the DHCP client are not in the same LAN, and the DHCP relay assumes the relay service between the DHCP client and the server in different network segments, and relays the DHCP protocol message to the destination DHCP server across network segments, so that DHCP clients on different networks can share a DHCP server. When the client applies for an address across network segments, the DHCP client obtains an IP address and other network parameters dynamically through DHCP relay.

[0044] The embodiment of the present invention expands the DHCP option of the DHCP message, and expands the functions of the D...

Abstract

The invention discloses a method and equipment for managing a customer address table. The method comprises the following steps of: after a DHCP (Dynamic Host Configuration Protocol) request message sent from a DHCP client is received by a DHCP relay, establishing a corresponding customer address entry; adding a security option into the message and then sending the processed message to a DHCP server; after a DHCP release massage is received by the DHCP server, if judging that an address of the DHCP relay is recorded in a corresponding IP (Internet Protocol) address lease and the DHCP relay is labeled with an opened security function, forwarding the released message to the DHCP relay; or after the DHCP server finds out that the IP address lease is expired, if judging that the address of the DHCP relay is recorded in the corresponding IP (Internet Protocol) address lease and the DHCP relay is labeled with the opened security function, generating the DHCP released massage according to a corresponding client address and sending the DHCP released massage to the DHCP relay; after the DHCP relay receives the released message sent by the DHCP server, deleting the corresponding customer address entry. By utilizing the method provided by the invention, the customer address table on the DHCP relay can be aged in time so that network expenditures can be reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a user address table management method and equipment applied to a network system including a DHCP client, a DHCP relay and a DHCP server. Background technique [0002] DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is used to dynamically assign network configuration parameters such as IP addresses to network devices. [0003] DHCP adopts the client / server communication mode. The client submits a configuration request to the server, and the server returns the corresponding configuration information such as the IP address assigned to the client to realize the dynamic configuration of the IP address and other information. [0004] DHCP is only applicable when the DHCP client and server are in the same subnet. For dynamic host configuration, it is necessary to set up a DHCP server on all network segments, which is obviously very uneconomical. ...
