VLAN information management system and method for dhcp RELAY termination sub-interface

Abstract

The invention discloses a VLAN (Virtual Local Area Network) information management system and method of a DHCP (Dynamic Host Configuration Protocol) RELAY termination sub-interface, and relates to the field of BTS (Base Transceiver Station) access network management service in an IPRAN (IP Radio Access Network). The system comprises DHCP clients, DHCP equipment and a DHCP server, wherein the DHCP equipment comprises a DHCP RELAY module and an IP protocol stack module; the DHCP RELAY module comprises a VLAN information memory module, a VLAN information searching module, a DHCP protocol module and a VLAN information issuing module; the IP protocol stack module comprises a VLAN information reporting module and an IP protocol stack data transceiver packet module. The VLAN information management system and method of the DHCP RELAY termination sub-interface have the advantages that other DHCP clients are not easily influenced during use, the normal work of other DHCP clients is not obstructed, and not only can the risk of network service be obviously reduced, but also the network stability and security can be enhanced and better experience can be provided for users.

Description

technical field [0001] The invention relates to the field of BTS (base station) access network management services in an IPRAN (IP Radio Access Network, IP wireless access network) network, in particular to a VLAN information management system and method for a DHCP RELAY termination sub-interface. Background technique [0002] With the development of the mobile Internet era, the telecom business has gradually changed from the original voice service to the data service; while major operators are increasing investment in wireless networks and increasing the construction of wireless base stations, they need to build a larger mobile data network. The transmission network supports the transmission and carrying of big data. [0003] At present, there are often multiple service types such as data, voice, and video in a single user network; when the user network is used, at first, different VLAN Tags (labels) are encapsulated for different service types by VLAN (Virtual Local Area N...

Problems solved by technology

[0008] After the DHCP client that does not need the DHCP response packet receives the DHCP response packet, it may affect the DHCP client (for example, the DHCP client that does not need the DHCP response packet does not discard the DHCP response packet, but receives and processes the DHCP response packet ), thereby hindering the normal operation of the DHCP client and increasing the risk of network services
