Mobile IP is to meet the Mobile node in the Mobile connectivity and keep its design. Mobile IP now has two versions, respectively for Mobile IPv4 (RFC 3344, replaced the RFC 3,220, 2002) and Mobile RFC IPv6 (RFC 3775). Use extensively at present is still Mobile IPv4.
The simplest, mobile IP technology is making computers in the Internet and LAN without any restrictions of real-time roaming, also called mobile computer technology.
A professional explanation, mobile IP technology is the mobile node (computer/server/network etc.) to fixed network IP address, realize the roaming across different segment, and ensure the function of network based on IP network access roaming process does not change.
Mobile IP network roaming function
Apply to all mobile IP based on TCP/IP network environment, it provides a broad network infinite roaming services. For example, in the user to leave Beijing office, travel to Shanghai branch, simply moving nodes (for example: laptops, PDA devices connected to the Shanghai branch network), so users can enjoy in Beijing with the same company all the operation. Users can still use the Beijing office of Shared printer, or can still visit Beijing office colleagues in the computer database resources and related to share files, Such various operation, let users feel themselves in the field, the colleague also feel you have to travel outside. In other words: mobile IP applications let users "home" network everywhere that can no longer endure "home" and "business" mobile node because of all the bitterness etc.
The key technology of mobile IP
Agent search: is calculated for judging yourself whether in the node roaming status.
To address: is the mobile node net moved from outside the agency of temporary address.
Login: is the mobile node net arrived on the authentication, registration, and establish a series of process.
Tunnel: is the agent and the temporary establish between agency two-way data channel
