An Integrated Addressing Architecture: For the Internet and the Telephony Network
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
The Internet has and will continue to change the way we communicate with each other. It opens up new possibilities for global communication. But the number of services is growing, and you get more and more addresses to keep track of – one or more for each service (email, homepage, etc.). Not only that, the addresses are tied to your employer, school, or service provider. That is, they are not very portable and persistent. Another problem is how to integrate Internet telephony with ordinary telephony. Besides setting up the necessary infrastructure, for example gateways, one of the biggest problems is the addressing incompatibility. Phones on the telephone network use telephone numbers while hosts on the Internet use IP addresses or domain names. How can you call a host named foo.ellemtel.se from an ordinary telephone, as you can only dial numbers?
This thesis begins with a general introduction to concepts and previous work related to the problems described above. Then two approaches aiming to solve these problems are presented. They are based on Unique Identification Numbers, or UINs, which are globally unique, persistent, and portable addresses. All of your addresses can be aggregated under one UIN, which acts as an alias for your real addresses. A real address could be found by specifying an UIN along with the desired service. And since UINs have E.164 number format, they can be used on both the Internet and in the telephony network, thus eliminating the incompatibility problem. For example, when you send an email to an UIN the real email address will be looked up and used transparently to the user.
The UIN architecture is based on DNS and directory services (LDAP, Whois++, etc.), and lives side-by-side with normal addressing. The scalability of DNS is combined with the flexibility of directory services.
