It means that to reduce handover delay and data packet loss rate so as to achieve seamless handover, however, current network protocols and handover process can not satisfy these needs. As a result, the handover technology, especially under the cheap ralph lauren polo shirts mobile IPv6, is the key issue facing in the real-time applications of the next-generation network environment, which is worthy of research, and also the core contents of this paper. This paper describes the basic mechanism of IPv6 protocol and MIPv6 handover problems in details. The handover ralph lauren polo shirts delay of the standard MIPv6 protocol is a little longer, which is easy to cause the communication interruption and data packet loss. So it can not meet the needs of real-time application and sensitive data loss discount wedding dresses applications such as VoIP.The Paper expatiates on the expansion technologies of cheap wedding gown dresses handover protocol, such as fast handover technology for custom made prom dresses, smooth handover technology for MIPv6, Hierarchical MIPv6, analyzing and comparing performances of series of handover expansion technology. Although F-MIPv6 and HMIPv6 improve handover performance of MIPv6 network to some extent, they still have some drawbacks in some cases. For example, HMIPv6 handover performance is not better than basic MIPv6 when mobile terminal devices handover in different subnets, because of the addition of interactive signal in networks.
