Implementation of an IPv4/IPv6 Translation Gateway based on SOPC technology
Hu Xiao · Journal of Guangzhou University · 2008
As the key device of IPv4-IPv6 heterogeneous network interconnection,an IPv4/IPv6 Translation Gateway has to support high forward speed,less time-delay and bearing heavy communication load.However,there is no existing solution published to satisfy the requirement.In this paper,a solution of IPv4/IPv6 Translation Gateway based on SOPC(System on Programmable Chip) technology is proposed.It is based on top-down design methodology.VHDL programming and schematic design are both used in the development course and the system is implemented on one FPGA chip.Test results show that its maximum forward rate is 800 Mbps and its delay time is 40ns from v4 to v6 network,and 96ns from IPv6 to IPv4.
