Software Defined
Network (SDN), with its great advantage of isolating data plane from control
plane, has become a focus in recent years, but more and more companies and
operators find in practice that, the performance status of SDN control plane
becomes a key constraining SDN commercial deployment and applications.
Recently, BII - Global SDN Certified Testing Center (SDNCTC, www.sdnctc.com/en),
after releasing RYU Controller Performance
Test Report, OpenDaylight Controller
Performance Test Report, again released ONOS
Controller Performance Test Report, it tested a number of performance
indicators of the mainstream open source controller ONOS and the test results are
subject to rendering visualization in the report.
This test is carried out specifically for
ONOS (standalone mode and cluster mode) southbound OpenFlow performance,
including control channel capacity test, topology discovery time test, PACKET
OUT rate test, FLOW MOD sending rate test, end-to-end link establishment time
test and role election time test. Standalone mode means to test one ONOS
controller, while cluster mode means to test multiple ONOS controllers.
It is found
during testing that, regarding the ONOS FLOW MOD
sending rate test, the
performance gap between standalone mode and cluster
mode is very obvious;
In addition, there will be obvious performance reduction when a large
number of switches coupled with topology discovery time under complex network topology
and end-to-end link establishment time, detailed test data can be found in the
original report. With clear and detailed data and charts, the entire "ONOS
Controller Performance Test Report" shows the complete test results in a scientific
and comprehensive manner, providing reliable data support for SDN network
performance assessment testing and commercial deployment for users.
Supported by OFsuite_Performance test tool,
which is one of OFsuite series test tools independently developed by BII-SDNCTC
and intended for performance test of OpenFlow controller. It can simulate
different network topologies and all OpenFlow events and effectively balance
the controller’s handling capacity of OpenFlow messages. This test
automatically generates data graph and performance test report.
Up to
now, BII - SDNCTC has completed testing of RYU, OpenDaylight,
ONOS and other mainstream open source controllers and issued corresponding test
reports, the director of SDNCTC Li Zhen said in an interview: "In the
previous SDNFV Fest testing activity, we found that there are significant
differences between performance test results of controllers provided by
different vendors, the Global SDN Certified
Testing Center has
begun to provide performance testing services for commercial-grade controllers,
to meet more customized testing requirements, assist applying enterprises to
improve controller performance, break through technology bottlenecks, promote in-depth
SDN commercial deployment. "
