As the Internet evolves towards ubiquity, the key research targets include security and trust, programmability, manageability and mobility.
In its 25-year lifetime, the Internet has succeeded beyond the wildest dreams of its creators in changing the way people live, work and play – and increased in size by seven orders of magnitude. The simple, original Internet architecture (16 specification documents) has increased to several hundred additional protocols and extensions. Networks based upon this complex architecture are increasingly difficult to manage, so that the qualities of service meet the needs of well over one billion users.
Security is also a more complex issue today. The original Internet was designed in an era of mutual trust. Many of the protocol additions/ extensions have had to retrofit protection mechanisms to reflect the less trustworthy current environment, and the volume and types of attempts to subvert the Internet can only continue to increase.
There is now considerable expertise in networking research in Scotland, addressing the practical aspects of networking, together with leading theoretical work on performance analysis and security in networked systems. The research challenges in this area cover a very wide range. Work is already in progress at Glasgow and St Andrews on manageability, and there is already planned collaboration on basic network architecture. This gives an excellent basis for research on security and trust, as well as on mobility. Securing the internet against myriad current and future exploits is the single most critical challenge to resolve for the successful exploitation of the Next Generation Internet, and it is one that requires a return to first principles and collaboration between networking practitioners and theorists – an area where SICSA plans significant investments.
