Optimization Design For Terminal Handover Protocol In The New Internet

The New Internet separates the identity attributes and location attributes of the IP address in traditional network,so that the mobility problem in traditional network can be solved.But with the continuous expansion of mobile internet application,users of mobile network service quality and efficiency requirements are also getting higher and higher.At present,only the support of terminal mobility is realized in the new internet mobility protocol,and there are still many problems in the network service quality and efficiency,such as serious packet loss during packet switching and large handover delay,so that users of high-quality,efficient communication needs can not be met.Therefore,this paper analyzes and studies the mobility protocol under the new internet architecture,and propose solutions to the existing problems of the new internet mobility protocol,improves the mobile related technology of mobile node,thereby improving the communication quality and the communication efficiency of the mobile network.This paper first introduces some protocol standards related to mobility and the research status of related mobile handover technology at home and abroad.It points out that the existing mobility protocols exist in the new internet,such as the obvious packet loss during the mobile handover and the large handover delay.And analyzes the specific causes of these problem,and then this paper proposes the corresponding improvement program for the above problems.First,the concept of the mobile node's home domain is added to the original protocol,and the handover class is redefined according to the difference between the access switching routers after the mobile node is switched.Second,two improvement strategies are proposed for the mobile node and the correspondent node respectively in the handover mechanism.On the side of mobile node,pre-handover mechanism is added.Before the mobile node switches to the new access switching router,allocates the corresponding mapping relation for the mobile node,and then direcly uses it after switching.On the side of correspond node,the concept of "active node" is added,and the active node can directly communicate with the identity mapping server of the mobile node's home domain to obtain the latest mapping relationship of the mobile node,thus reducing the packet loss rate and reducing the handover delay to achieve the overall optimization of the agreement.At last,this paper compares the above improvement scheme with the former scheme,and sets up the experimental platform under Linux system,tests the performance of the mobile handover before and after the improvement,and compares the test result with the previous investigation and analysis.The improvement scheme proposed in this paper achieves the effect of protocol optimization,and makes the mobile terminal handover mechanism of the new internet more flexible.This has a certain theoretical value for the improvement of mobility related protocols.
