Abstract
The combination of ALG and NAT-PT can achieve the communication between IPv6 and IPv4 network, but there are still many problems because of network complexity. This article combines NAT-PT and uses class E address pool to give a comprehensive and detailed analysis of improvements about the problems in the process of ALG communication, studying initiating communication process from the IPv4 and IPv6 ends, analysis of the relationship between the address pool mapping, to experiment the scheme and verify the feasibility. The scheme solves the NAT-PT gateway at both ends of the same and different protocol communications much easier, and also solves the shortage problem in IPv4 address of address pool.
