+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 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.

 Rationale for decisions
 -----------------------
-.. result analysis, pass/fail
+
+* 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.
+
 
 Conclusions and recommendations
 -------------------------------
 
-.. did the expected behavior occured?
+* 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.
