1.5: Experiment A&B - Topology (Switch, Link) Event Latency

Test Env:

• Server: Dual XeonE5-2670 v2 2.5GHz; 64GB DDR3; 512GB SSD
• System clock precision is +/- 1 ms
• 1Gbps NIC
• JAVA_OPTS="${JAVA_OPTS:--Xms8G -Xmx8G}"

• org.onosproject.net.topology.impl.DefaultTopologyProvider
  name=maxBatchMs, type=integer, value=0, defaultValue=50, description=Maximum number of millis for whole batch
  name=maxEvents, type=integer, value=1, defaultValue=1000, description=Maximum number of events to accumulate
  name=maxIdleMs, type=integer, value=0, defaultValue=10, description=Maximum number of millis between events

Test Procedure:

• switch event generate on ONOS1 by connecting ovs switch to it; 
• record tshark (tcp syn-ack) and graph event timestamp to calculate differences.
