Rethinking the design of the Internet: The end to end arguments vs the brave new world docx

... design of the Internet, and of a loss of control by the 789 user. Whether one chooses to see these trends as a natural part of the growing up of the Internet 790 or the fencing of the West, they ...

The bold line (at the top of the graph) shows the ... shows, when the sending rate of the UDP flow is small, the TCP flows have high goodput, and use almost all of the bandwidth on the R1-R2 link. When the sending r...

The lack of a unified “theory of ecology” and the existence instead of a fragmented body of “ecological theory”is evidenced by the relative use of these two terms in the scientific ... species. To get a clearer understanding of why it is anachronistic to refer to all of this as the theory of evolution, I suggest we look to ecology—evolution’s sib...
