Problems solved by technology

However, as the access authentication technology based on the DHCP protocol is being gradually implemented in various telecommunication services, the increase in the number of these service products also greatly increases the demand for original IP addresses, and the original address resources may be far away. It is far from meeting the demand for addresses brought about by the growth of business volume
At the same time, if the DHCP access system is deployed in units of business categories, it will inevitably bring huge expenses to service providers

Embodiment Construction

[0027] The invention will be described in more detail hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0028] figure 1 It is a schematic structural diagram of a service network access system 100 according to an embodiment of the present invention. The service network access system 100 includes a service terminal 102 , a DHCP server 104 and an authentication server 106 .

[0029] The DHCP server 104 is used to receive and forward the authentication request sent by the service terminal 102, and at the same time complete the IP address assignment work required by the service. On the one hand, the DHCP server 104 can forward the received authentication request sent by the service terminal 102 to the authentication server 104 . In an embodiment, the authentication server 104 may be a RADIUS (remote authentication dial in user service, remote authentication dial in user service) server, and is used for veri...

Abstract

The invention provides a network address distributing method, a DHCP server, an access system and a method thereof, relating to the technical field of data communication. A network address distributing method comprises the steps: receiving a DHCP discovery report transmitted from a service terminal, wherein the discovery report comprises the service identification of the service type requested bythe service terminal; searching an unoccupied ID address corresponding to the service identification in an address pool, wherein the IP address in the address pool comprises status attributes respectively corresponding to the different service types, and the status attributes comprise the unoccupied or the occupied attributes; and transmitting the searched unoccupied ID address to the service terminal through a DHCP proposal report. The invention realizes the repeat use of the same IP address for the different service types, saves address expenditure, and relieves the increasing tensional address use condition.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a network address allocation method, a DHCP (dynamic host configuration protocol, dynamic host configuration protocol) server, access system and method. Background technique [0002] The currently used DHCP system only includes one address space, which can realize fast access control operation for a single telecommunication service. However, as the access authentication technology based on the DHCP protocol is being gradually implemented in various telecommunication services, the increase in the number of these service products also greatly increases the demand for original IP addresses, and the original address resources may be far away. It is far from meeting the demand for addresses brought about by the growth of business volume. At the same time, if the DHCP access system is deployed in units of service categories, it will inevitably bring huge expenses to...
