Fast-packet vs circuit switch and bent pipe satellite network architectures

摘要

The Ka frequency band has the potential to enable rapid deployment of broadband multimedia services around the world. The optimal satellite payload architecture for these services depends on the needs and constraints of the Network Service Provider (NSP) and the limitations of technology. TRW has developed a methodology that enables satellite-based NSPs to understand the business implications of a variety of payload and network architectures. TRW also conducted a study to quantify the differences between competing architectures in terms of throughput and financial performance.
