 juju_epc
 ^^^^^^^^
+The Evolved Packet Core (EPC) is the main component of the System Architecture
+Evolution (SAE) which forms the core of the 3GPP LTE specification.
 
+vEPC has been integrated in Functest to demonstrate the capability to deploy a
+complex mobility-specific NFV scenario on the OPNFV platform. The OAI EPC
+supports most of the essential functions defined by the 3GPP Technical Specs;
+hence the successful execution of functional tests on the OAI EPC provides a
+good endorsement of the underlying NFV platform.
+
+This integration also includes ABot, a Test Orchestration system that enables
+test scenarios to be defined in high-level DSL. ABot is also deployed as a
+VM on the OPNFV platform; and this provides an example of the automation
+driver and the Test VNF being both deployed as separate VNFs on the underlying
+OPNFV platform.
+
+The Workflow is as follows:
+ * Deploy Orchestrator
+    Deploy Juju controller using Bootstrap command.
+ * Deploy VNF
+    Deploy ABot orchestrator and OAI EPC as Juju charms.
+    Configuration of ABot and OAI EPC components is handled through
+    built-in Juju relations.
+ * Test VNF
+    Execution of ABot feature files triggered by Juju actions.
+    This executes a suite of LTE signalling tests on the OAI EPC.
+ * Reporting
+    ABot test results are parsed accordingly and pushed to Functest Db.
+
+Details of the ABot test orchestration tool may be found in `[15]`_
