  3. The problem • SDN flow rule updates: 1ms to 10ms • RP 168 switch point accuracy ~10µs • We’ve got a problem!

  4. The Solution • Add new flow rule to switch based on new packet header value – then wait ~10ms • The source changes the packet header value at RP 168 switch point • Later, remove old flow rule from switch Live demonstration on COTS Ethernet switch in demo room
