In this book, available bandwidth estimation tools including Delphi, Spruce, and Pathload are evaluated. Among all, Pathload is the most reliable tool that considers the IC/CS phenomenon. Pathload sends multiple trains called fleets. After each fleet is sent, statistical evaluation of the inter- packet time gaps at the destination compared to the inter-packet time gaps at the sender determines whether the trend of the inter-packet time gaps in that fleet has been increasing, non-increasing, or undeterminable. The transmission rate for the next fleet is adjusted based on the trend of the...
