-Overview of test results
-------------------------
-
-.. general on metrics collected, number of iterations
-
-The virtual Traffic Classifier (vtc) Scenario supported by Yardstick is used by 4 Test Cases:
-
-- TC006
-- TC007
-- TC020
-- TC021
-
-
-* TC006
-
-TC006 is the Virtual Traffic Classifier Data Plane Throughput Benchmarking Test.
-It collects measures about the end-to-end throughput supported by the
-virtual Traffic Classifier (vTC).
-Results of the test are shown in the Dashboard006_
-The throughput is expressed as percentage of the available bandwidth on the NIC.
-
-
-* TC007
-
-TC007 is the Virtual Traffic Classifier Data Plane Throughput Benchmarking in presence of
-noisy neighbors Test.
-It collects measures about the end-to-end throughput supported by the
-virtual Traffic Classifier when a user-defined number of noisy neighbors is deployed.
-Results of the test are shown in the Dashboard007_
-The throughput is expressed as percentage of the available bandwidth on the NIC.
-
-
-* TC020
-
-TC020 is the Virtual Traffic Classifier Instantiation Test.
-It verifies that a newly instantiated vTC is alive and functional and its instantiation
-is correctly supported by the underlying infrastructure.
-Results of the test are shown in the Dashboard020_
-
-
-* TC021
-
-TC021 is the Virtual Traffic Classifier Instantiation in presence of noisy neighbors Test.
-It verifies that a newly instantiated vTC is alive and functional and its instantiation
-is correctly supported by the underlying infrastructure when noisy neighbors are present.
-Results of the test are shown in the Dashboard021_
-
-* Generic
-
-In the Generic scenario the Virtual Traffic Classifier is running on a standard Openstack
-setup and traffic is being replayed from a neighbor VM. The traffic sent contains
-various protocols and applications, and the VTC identifies them and exports the data.
-Results of the test are shown in the DashboardVTC.
-

-
-
-For all the test cases, the user can specify different values for the parameters.
-
-* Generic
-
-The results listed in the previous section have been obtained, using a
-standard Openstack setup.
-The user can replay his/her own traffic and see the corresponding results.
-
-Rationale for decisions
------------------------
-
-* TC006
-
-The result of the test is a number between 0 and 100 which represents the percentage of bandwidth
-available on the NIC that corresponds to the supported throughput by the vTC.
-
-
-* TC007
-
-The result of the test is a number between 0 and 100 which represents the percentage of bandwidth
-available on the NIC that corresponds to the supported throughput by the vTC.
-
-* TC020
-
-The execution of the test is done as described in the following:
-
-- The vTC is deployed on the OpenStack testbed;
-- Some traffic is sent to the vTC;
-- The vTC changes the header of the packets and sends them back to the packet generator;
-- The packet generator checks that all the packets are received correctly and have been changed
-correctly by the vTC.
-
-The test is declared as PASSED if all the packets are correcly received by the packet generator
-and they have been modified by the virtual Traffic Classifier as required.
-
-
-* TC021
-
-The execution of the test is done as described in the following:
-
-- The vTC is deployed on the OpenStack testbed;
-- The noisy neighbors are deployed as requested by the user;
-- Some traffic is sent to the vTC;
-- The vTC change the header of the packets and sends them back to the packet generator;
-- The packet generator checks that all the packets are received correctly and have been changed
-correctly by the vTC
-
-The test is declared as PASSED if all the packets are correcly received by the packet generator
-and they have been modified by the virtual Traffic Classifier as required.
-
-* Generic
-
-The execution of the test consists of the following actions:
-
-- The vTC is deployed on the OpenStack testbed;
-- The traffic generator VM is deployed on the Openstack Testbed;
-- Traffic data are relevant to the network setup;
-- Traffic is sent to the vTC;

-Conclusions and recommendations
--------------------------------
-
-* TC006
-
-The obtained results show that the virtual Traffic Classifier can support up to 4 Gbps
-(40% of the available bandwidth) correspond to the expected behaviour of the virtual
-Traffic Classifier.
-Using the configuration with SR-IOV and large flavor, the expected throughput should
-generally be in the range between 3 and 4 Gbps.
-
-
-* TC007
-
-These results correspond to the configuration in which the virtual Traffic Classifier uses SR-IOV
-Virtual Functions and the flavor is set to large for the virtual machine.
-The throughput is in the range between 2.5 Gbps and 3.7 Gbps.
-This shows that the effect of 2 noisy neighbors reduces the throughput of
-the service between 10 and 20%.
-Increasing number of neihbours would have a higher impact on the performance.
-
-
-* TC020
-
-The obtained results correspond to the expected behaviour of the virtual Traffic Classifier.
-Using the configuration with SR-IOV and large flavor, the expected result is that the vTC is
-correctly instantiated, it is able to receive and send packets using SR-IOV technology
-and to forward packets back to the packet generator changing the TCP/IP header as required.
-
-
-* TC021
-
-The obtained results correspond to the expected behaviour of the virtual Traffic Classifier.
-Using the configuration with SR-IOV and large flavor, the expected result is that the vTC is
-correctly instantiated, it is able to receive and send packets using SR-IOV technology
-and to forward packets back to the packet generator changing the TCP/IP header as required,
-also in presence of noisy neighbors.
-
-* Generic
-
-The obtained results correspond to the expected behaviour of the virtual Traffic Classifier.
-Using the aforementioned configuration the expected application protocols are identified
-and their traffic statistics are demonstrated in the DashboardVTC, a group of popular
-applications is selected to demonstrate the sound operation of the vTC.
-The demonstrated application protocols are:
-- HTTP
-- Skype
-- Bittorrent
-- Youtube
-- Dropbox
-- Twitter
-- Viber
-- iCloud
