With the boom of Internet, IP-based applications, such as WWW and multimedia, bave been an essential part of our life, and there is an ever-increasing demand for accessing high-speed Internet services anywhere and anytime. This trend unavoidably has huge impacts on the design of the next-generation satellite systems. On the other hand, with its broadcasting nature and unique coverage, satellite systems also can play an important role in the next-generation Internet. For example, satellite systems can be a good driver for the deployment of IPv6 in the Internet, and can provide a fast way to reach end-users because they do not rely on construction of a high-speed terrestrial networks. The workshop proceedings will focus on the IP networking of next-generation satellite systems. Topics include IPv6 over satellites, new architectures of next-generation satellite systems, satellite and terrestrial network integration, network monitoring and measurement, and perfmance enhancement.
