Hi! > How to measure the workload of a switch?
Probably the fancy way is to query for switch stats using the "OFPT_STATS_REQUEST" message. Please refer to ofp_stats_request class in Pox and section 5.3.5 in OpenFlow 1.0 specification. If you are using Open vSwitch, I think you can also use OVSDB protocol for such queries, but I've never tried it by myself. -- Att Lucas Brasilino MSc Student @ Federal University of Pernambuco (UFPE) twitter: @lucas_brasilino
