+============================
+ApexLake is a framework that provides automatic execution of experiments and related data collection to enable
+a user validate infrastructure from the perspective of a Virtual Network Function (VNF).
+In the context of Yardstick, a virtual Traffic Classifier (vTC) network function is utilized.
-Hardware dependencies to run the framework
-==========================================
-In order to run the framework some hardware dependencies are required to run ApexLake.
-The framework needs to be installed on a physical node where the DPDK packet DPDK-pktgen_
-can be correctly installed and executed.
-That requires for the packet generator to have 2 NICs DPDK_ Compatible.
+Framework Hardware Dependencies
+===============================
+In order to run the framework there are some hardware related dependencies for ApexLake.
-The 2 NICs will be connected to the switch where the Openstack VM network is managed.
+The framework needs to be installed on the same physical node where DPDK-pktgen_
+is installed.
+The installation requires the physical node hosting the packet generator must have 2 NICs
+which are DPDK_ compatible.
-The switch is required to support multicast traffic and snooping protocol.
+The 2 NICs will be connected to the switch where the OpenStack VM network is managed.

+The corresponding ports to which the cables are connected need to be configured as VLAN trunks
using two of the VLAN IDs available for Neutron.
-The mentioned VLAN IDs will be required in further configuration steps.
