Blackbird - Flow Subsystem: Flow Install Burst Throughput

Reference:

• for Test Plan see: Test Plan - Perf & Scale-out; 
• ONLabTest script - https://github.com/opennetworkinglab/ONLabTest:flowTP1g.

System Environment:

• Server: Dual XeonE5-2670 v2 2.5GHz; 64GB DDR3; 512GB SSD
• 1Gbps NIC
• JAVA_OPTS="${JAVA_OPTS:--Xms8G -Xmx8G}"
• (no flow rules backup)

"Constant-Load" Test Conditions:

• F = 122500 - total # of flows installed
• N: # of neighboring ONOS's for flows to be installed from a server installing flows
• S: #servers installing flows
• SW = 35 - total # of switches (Null Devices) connected to ONOS cluster evenly distributed to active ONOS nodes
• FL: # flows to be installed on each switch

Command: python3 $ONOS_ROOT/tools/tests/bin/flow-tester.py -f FL -n N -s servers

Iterations on each test:20 (after 4 warm-up runs)

Result Discussions:

1. When N = 0, all flow installation from all nodes are local, i.e. flows are for local switches. This are the cases when no EW communication is needed for flow operations;
2. When N is "all", the neighbor setting N +1 is equal to the cluster size of the test. For instance, when testing with 3-node cluster, N=2. This are the cases when "maximum" of EW communication is needed for each node generating flows.
3. As the result shows, flow installation throughput performance increases with cluster size.
