Weekly Report -- 3/08/2012




Not a lot of progress this week. Finally worked through and realised what was causing the problem with my write-metadata instruction -- the execution order wasn't what I expected, so packets would be returned to the controller with information about a flow before the write-metadata instruction was executed, which means that it appears like the instruction hasn't been executed. Waiting on a response about how the specification expects things to work.

Brad and I brought the HP openflow switch back out and I had another crack at getting RouteFlow running on it. Made more progress this time, partially due to improvements in the latest RouteFlow code, and partially because I have a bit more familiarity with Open vSwitch, which was the point of failure last time we tried. Didn't quite get it all up and running, but the basic test environment + GUI seemed to work pretty nicely.
