Executive Summary

Achieving maximum throughput over 10Gbps WANs with leading, high-performance storage systems. This paper first explores the various fundamental bottlenecks of TCP that impair conventional network file systems and transfer protocols, and then introduces in contrast the design principles of an innovative, patented data transport technology, Aspera fasp, as a solution capable of moving petabyte of data on a daily basis. The paper also summarizes the fundamental performance limitations of TCP including its congestion control and reliability - the associated underperformance is qualitatively and quantitatively analyzed. The key role Aspera fasp can play in realizing the "virtual data center" of the future is explained.
