Handling of IP-Addresses in the Context of Remote Access
MetadataVis full innførsel
For various reasons (e.g., security, lack of IPv4-addresses) the services in the home smart space only use private IP addresses. This is unfortunate in the remote service access since these addresses frequently appear in responses sent from a service in the remote smart space (e.g., your home) to the visited smart space (e.g., your friend’s home).The Internet Engineering Task Force (IETF) provides some solutions and workarounds for the problem caused by NAT. In this project, the challenge to me is to summarize the available options, rank the options according to which one is preferred for the RA-scenario. I will come up with my practical NAT traversal techniques by testing and gathering data on the reliability of NAT traversal techniques since none of the existing ones seems to work well. A demonstration of the key features will be shown in the thesis. NAT traversal techniques apply to TCP and UDP need to be researched in advance. Handling of peers behind all kinds of NAT need to be tested and determined for the communication. The result of the paper will well improve the evaluation of specific issues on NAT and the creating of an UNSAF proposal.
