      Replace license symbols with {{{ }}}-enclosed license blocks. · 6df609a9
      Eric Eide authored
      This commit is intended to makes the license status of Emulab and
      ProtoGENI source files more clear.  It replaces license symbols like
      "EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
      blocks that contain actual license statements.
      
      This change was driven by the fact that today, most people acquire and
      track Emulab and ProtoGENI sources via git.
      
      Before the Emulab source code was kept in git, the Flux Research Group
      at the University of Utah would roll distributions by making tar
      files.  As part of that process, the Flux Group would replace the
      license symbols in the source files with actual license statements.
      
      When the Flux Group moved to git, people outside of the group started
      to see the source files with the "unexpanded" symbols.  This meant
      that people acquired source files without actual license statements in
      them.  All the relevant files had Utah *copyright* statements in them,
      but without the expanded *license* statements, the licensing status of
      the source files was unclear.
      
      This commit is intended to clear up that confusion.
      
      Most Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the Affero GNU General Public License, version 3
      (AGPLv3).
      
      Most Utah-copyrighted files related to ProtoGENI are distributed under
      the terms of the GENI Public License, which is a BSD-like open-source
      license.
      
      Some Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the GNU Lesser General Public License, version 2.1
      (LGPL).

      1)Added 3 new sensors - Loss, Rtt and AvgThroughput. · 80d60cf6
      Pramod R Sanaga authored
      2) Modified SensorList.h, SensorList.cc and lib.h to include the new sensors.
      3) made changes in UdppacketSensor to accommodate the above new ones.
      4) Added a script makeUdpPlots.py to create gnuplot graphs from the output
      of UDP sensors.

      1) Added a UdpSensorList class. · a1cfdc36
      Pramod R Sanaga authored
      2) Replaced gettimeofday calls with TSC register reads.
      3) Removed all recvfrom calls - no overhead for those calls & copying
      packets to user space - this does not adversely affect performance.
      4) More graphs!! and streamlined error/warning messages to be put into a single
      log file.

      1) Removed potential memory leaks & added destructors for all classes. · 4ff262c1
      Pramod R Sanaga authored
      2) Changed the number of redundant ACKs being sent to vary based on ACK size.
      3) Libpcap loss at the sender is now handled - by sending packet sizes and
      send times in the packets and having them echoed back in ACKs. Reordered
      ACKs are detected as being seperate from libpcap loss and are ignored.
      4) updated the plot creation python script to give out loss, maximum delay graphs.

      Modified the Design doc to reflect discussion with Rob & Jon. · 47925cee
      Pramod R Sanaga authored
      Changed the throughput calculation, cleaned up MaxDelay and
      all other files in general to be more readable.
      
      Added checks for out of order ACKs, and error conditions to
      check for invalid packets.
      
      sendto() calls block on Linux - verified this on
      planet lab - made the writes to UDP socket non-blocking.
