An Innovative Video Phone System in DHCP and Firewall Network Environment
نویسنده
چکیده
In the decade, the video phones have brought the intense interests for its service. However, the limited network bandwidth, the unfriendly operations like IP dialing, and the dynamic host configuration protocol, DHCP, environment bound the development. An innovative video phone system, IVPS, based on a creative data transmission architecture has been presented in the paper, especially the advantage of operating in the DHCP and firewall environment. Moreover, IVPS retains the traditional dialing way with telephone number and downward capability with the recent analog telephone. Therefore, the users can enjoy IVPS in their familiar operations. Key-Words: DHCP, video phone, Firewall, telephone.

DHCP (Dynamic Host Configuration Protocol) is widely deployed in resource allocation and intranet management. However, DHCP mechanism is not mandatory, and DHCP server can neither force DHCP clients to release their leases, nor enforce cooperation from externally configured hosts that are DHCP-unaware. Although new DHCP options such as DHCP reconfigure extension have been proposed, the basic pr...
