NAT64Equipment Performance And Network Deployment Scenarios Research

ABSTRACT:The IP address is the massive foundation for the future mobile Internet, networking and other applications in-depth development. And in our country has a serious shortage of IPv4addresses, the question of how the transition to IPv6becomes more urgent. IPv6uses128-bit address format, the huge address space that can solve the IPv4address shortage problem. However, due to IPv6is incompatible with IPv4, so in the current IPv4-based network environment, IPv6smooth transition has become the key to the success. Different evolution, different scenarios require different coping. NAT64technology with DNS64technology is a more viable means transition from dual-stack to the network that single-stack IPv6. Transition process can be achieved single-stack IPv6users to access most of the business. Therefore, the study of technology and networking NAT64deployment scenario is very necessary.In this paper, the application of technology in the background for NAT64thae one of the IPv6transition technology is analyzed, and do the research of the NAT64networking, technical analysis of equipment testing, raise the NAT64carrier-grade deployments.Through statistical analysis of the current network traffic and number of BRAS, SR device carries user analysis, summarized get NAT64device carrying capacity requirements; further NAT64device testing to verify the maturity of the equipment, ensure the realization of the basic functions for network testing support; the use of existing network equipment in the laboratory to simulate the current network structure to build a test environment for networking test, deploy NAT64first orbiting research problems under dual-stack, proposed distinction between the source address of the user circumvention methods and different user actions tests to verify the system. Secondly NAT64device in disaster recovery mode to study the existing network deployments, many cases were analyzed in multiple directions, from the operation and maintenance needs, CR position, CR safety considerations on the use of hot standby mode associated networking, select the master prepared to give up load balancing. Finally, according to the evolution of Different periods to make a scenario analysis, IDC hanging next to a centralized export and centralized CR MAN hanging next to compare the situation, and come to a more complete network deployment scenarios.
