+# vIPSec use case in ONAP
+This use case is composed of four virtual functions (VFs) including two
+IPSec gateways, a packet generator and a traffic sink, each running in
+separate Ubuntu Virtual Machines:
+
+ * [Packet generator][1]: Sends packets to the packet sink through the
+tunnel constructed thru IPSec. This includes a script that installs the
+packet generator based on packetgen[4].
+ * [IPsec gateways][2]: Two IPSec gateways constructed the secure tunnel
+for traffic transportation. This includes a script to install and configure
+the IPSec gateways thru VPP.
+ * [Traffic sink][3]: Displays the traffic volume that lands at the sink
+VM using the link http://192.168.80.250:667 through your browser
+and enable automatic page refresh by clicking the "Off" button. You
+can see the traffic volume in the charts.
+
+This set of scripts aims to construct the vIPSec use case in order to set
+up a secure tunnel between peers and improve its performance along with
+hardware acceleration technologies such as SRIOV and QAT.
+
+User can apply the helm chart named 'vipsec' inside the k8s/kud/demo folder
+to set up the whole use case. A fully-functional Kubernetes cluster, Virtlet
+as well as ovn4nfv-k8s[5] plugin need to be pre-installed for the usage.
+*[Place needs improvements] After having the virtual machines ready, please
+manually change the MAC address inside the ipsec.conf to enable the routing.
+And also start up the packetgen to send packet with src and dst defined in
+the templates/values.yaml inside the helm chart. Detail instructions will be
+put inside the helm chart.
+
+If you'd like to test the performance with QAT/SRIOV involved, first get
+these hardwares pre-configured. Then change the value of 'qat_enabled' and
+'sriov_enabled' inside templates/values.yaml of the helm chart accordingly.
+User could observe variance in throughput inside the traffic sink.
