Problems solved by technology

[0006] This method can also use the BootP protocol to replace the DHCP protocol, but there are two disadvantages in the BootP protocol: one, before configuration, the server must know the MAC address of the IP set-top box; two, the IP address is statically bound, when the IP resource is insufficient , it may cause a waste of IP addresses
When there are a large number of users in the network, but the IP resources are insufficient, and there will not be more than the total number of users logging in to the network at the same time, the static binding IP of the BootP protocol will cause an IP conflict problem.

Address and ID

[0029] The third step, as shown in the (2) step of the accompanying drawing 2, after all the DHCP servers in the network receive the request, if there is an idle IP address, a confirmation message will be sent back, and then as shown in the accompanying drawing 2 (3) ) step, send an IP lease contract, which includes the IP address of the DHCP server, the IP address provided to the set-top box, the gateway, the subnet mask, the lease period, and record the MAC address of the set-top box on the IP mapping table. If the requested information is from a different subnet, the subnet number must also be noted. If there is no free IP address in the DHCP server, then return the abnormal information that there is no IP...

Abstract

A method for dynamically distributing IP address on set-top box includes connecting client end module to IPTV set top box of Internet and using service end module to distribute and manage DHCP server of IP, utilizing set-top box at client end to monitor UDP port 67 and to send IP address leasing request as well as to configure TCP / IP, using server at service end to receive IP address leasing request of set -top box and to return confirmed IP address back as well as to change IP address mapping table on server.

Description

technical field [0001] The invention relates to the field of computer network communication and some related network communication protocols. technical background [0002] IPTV receiving terminal, that is, IPTV set-top box, is one of the key equipment of IPTV system. Its main functions include: supporting LAN or xDSL network transmission, receiving and processing IP data and video stream; supporting H.264, MPEG-2, MPEG-4 , WMV and Real video decoding; support corresponding CA technology; support HTML web browsing and online games, etc. [0003] Since IPTV is based on network transmission, the set-top box as a network access device should be set with network parameters such as IP address and gateway before use. If it is manually set up one by one in the actual project, it will greatly increase the labor cost of the operator, and the maintenance cost in the future will also increase accordingly. Therefore, in the design of the IPTV set-top box, the plug...
