InternetcleanupMobile poker stratagy IP is an Internet Engineering Task Force standard communications Protocol that is designed to allow mobile device users to move from one network to another while maintaining their permanent IP address. IntroductionMobile IP provides an efficient, scalable mechanism for node mobility within the Internet. Using Mobile IP, nodes may change their point-of-attachment poker stratagy to the Internet without changing their IP address. This allows them to maintain transport and higher-layer connections while moving. Node mobility

is realized without the need to propagate host-specific routes throughout the Internet routing fabric. ApplicationsMobile IP is most often found in wireless WAN environments where users need to carry their mobile devices across multiple LANs with different IP addresses. Examples of applications where sudden changes in network and poker stratagy IP-address can cause problems. The most common ones

are listed below:Remote Access VPNs,Microsoft Office and Windows,Database applications,Voice over IP.How Mobile IP WorksIn brief, Mobile IP routing works as follows. Packets destined to a mobile node are routed first to its home network -- a network identified by the network prefix of the mobile nodes home address. At the home network, the mobile nodes home agent intercepts such

packets and tunnels them to the mobile nodes most recently reported poker stratagy care-of address. At the endpoint of the tunnel, the inner packets are decapsulated poker stratagy and delivered to the mobile node. In the reverse direction, packets sourced by mobile nodes are routed to their destination using standard IP routing poker stratagy mechanisms.The Mobile IP protocol defines the following: an extension to ICMP Router Discovery which allows mobile nodes to discover prospective home agents and foreign agents; and the rules for routing packets to and from mobile nodes, including the specification of one mandatory tunneling mechanism and several optional tunneling mechanisms.FutureEnhancements

to the Mobile IP technique, such as Mobile IPv6 and Hierarchical Mobile IPv6 , are poker stratagy being developed to improve mobile communications poker stratagy in certain circumstances by making the processes more secure and more efficient.NetBIOS similarityReaders may be intrigued to know that, aside from the authentication, Mobile IP is literally concept-for-concept identical to NetBIOS in combination with the poker stratagy Microsoft Network Neighborhood services. Readers may also be surprised to know that, despite the conceptual similarity, at the time that an analysis was done no reference to RFCs 1001 and 1002, nor to the Microsoft Network Neighborhood, could be found in any of the Mobile IP RFCs or Draft RFCs.External linksIETFMobile IP Web ResourcesProtocols for Adaptive Mobile and Wireless Networkingde:Mobile IPzh:Mobile IPja:Mobile IP
