NOTES

• GUI things to watch out for
• line graphs that creep apart
• I believe this has something to do with the fact
  that the different lines are coming from
  different CPs.
• The only way to get them back in sync is to kill
  the graph and restart it.
• for the demo we will probably have one
  comprehensive GUI spec file and also have
  individual ones for each graph.
• so, you should be able to just kill the affected
  graph and restart it.
• line graphs disappearing from the display
• if the entry in the legend on the right side goes
  away, then the TCP connection for that sample has
  been lost.
• The only way to get it back is to kill the graph
  and restart it. (See note above)
• also see notes below about SIGPIPE.
• line graphs that display up and down tight
  zig-zag lines when they should be flat
• we dont know yet what causes this.
• you need to close all the graphs and kill the gui
  and restart it

3
NOTES (continued)

• We still occasionally get a data source that
  spontaneously turns off
• I havent had time to investigate this yet.
• They always seem to come back with the next
  iteration so it shouldnt be a big deal.
• SIGPIPE
• if MSRC or newGBNSC.init gets a SIGPIPE
• you will need to kill the GUI
• it will probably have lost some or all of its
  line graphs
• then kill and restart the offending MSRC or
  newGBNSC.init
• in PI_MTG_DEMO/COMBINED you should find runGBNSC
  and runMSRC scripts.
• then restart the GUI
• If it appears that the FPX has crashed
• you will need to kill and restart everything.
• All the way back to the INITALL.
• See PI_MTG_DEMO/README for directions on
  restarting everything.

• Each VCI turned on and off for each Demo.
• SA, DA and rate individually controlled for each
  VCI.
• 8 flows turned at initialization time.

JST V1 Hardware Performance Demo

• Objective - to showcase major performance
  characteristics of initial hardware
  configuration.
• Outline
• Scenario 1 all inputs receive data at 950 Mb/s
• alternate between sending packets randomly to all
  outputs sending to 3
• Phase 1 (10 seconds) all outputs receive 950
  Mb/s
• Phase 2 ( 1 second) ½ outputs receive 1.1
  Gb/s, ½ outputs receive 800 Mb/s
• Scenario 2 Two flows
• one bursty DG flow building up a backlog, but not
  overflowing
• one constant rate flow
• monitor lengths of the two queues
• Scenario 3 highlight one input
• exercise route table, general match filters,
  exact match filters
• demonstrate priority mechanism between routes and
  filters

• exercise route table, general match filters,
  exact match filters
• Use 3 Flows
• Each flow hits a different route
• Each of these 3 routes goes to a different output
  port
• Use an overriding EM filters for each flow

• Demonstrate Priorities
• EM gt GM gt Routes
