Subnet access method based on identity-position separate mapping mechanism

Abstract

The invention belongs to the technical field of network communication, particularly relates to a subnet access method based on an identity-position separate mapping mechanism. The method is used for accessing a terminal into a virtual tree network structure comprising a switch router and a subnet router to realize a micromotion protocol. The method comprises the steps of: establishing the virtual tree network structure in a default route mode; setting the route mode of the subnet router into a host route mode and setting the route mode for accessing the switch router into a policy route mode; and accessing the terminal into the subnet router. By the identity-position separate mapping mechanism, the invention realizes the micromotion protocol, solves the extensible problem of a network route, reduces the switching delay of the terminal among networks, overcomes obstacles existing when a heterogeneous terminal is accessed into a network, and avoids the generation of triangular route.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a subnet access method based on an identity and location separation mapping mechanism. Background technique [0002] After entering the 21st century with the rapid development of information technology, people's demand for communication technology and network technology is getting higher and higher. The Internet has become an indispensable part of people's work and life, and has become a huge driving force for social progress. In recent years, the scale of the Internet has expanded rapidly, and the number of users has increased by leaps and bounds. However, since the Internet was born more than 30 years ago, people's needs for the Internet have undergone significant changes, which has led to the gradual emergence of some original design flaws of the Internet. Poor mobility support is a huge bottleneck in the development of traditional Internet. [0003...

Problems solved by technology

Since HMIP adopts a single layer of routing point layering to reduce the number of mobility management nodes in the network, compared with other mobility protocols designed for mobility routing, it produces higher switching delays

[0014] In summary, cellular IP (Cellular IP), HAWAII, and hierarchical mobile IP (HMIP) are all protocols based on MobileIP, and the communication mechanism between terminals in the subnet is not perfect enough. Bidirectional data packets need to pass through the router at the apex of the subnet. There is no particularly optimized routing scheme for this
