+Dynamic Network Runtime Operations test specification
+=====================================================
+
+.. toctree::
+   :maxdepth: 2
+
+Scope
+=====
+
+The dynamic network runtime operations test area evaluates the ability of the
+system under test to support dynamic network runtime operations through the
+life of a VNF (e.g. attach/detach, enable/disable, read stats).
+The tests in this test area will evaluate IPv4 network runtime operations
+functionality. These runtime operations includes hotpluging network interface,
+detaching floating-ip from VM, attaching floating-ip to VM, updating subnet's
+DNS, updating VM instance port admin state and updating router admin state.
+
+References
+==========
+
+- DNS
+
+  - https://docs.openstack.org/newton/networking-guide/config-dns-res.html
+
+Definitions and abbreviations
+=============================
+
+The following terms and abbreviations are used in conjunction with this test
+area
+
+- API - Application Programming Interface
+- DNS - Domain Name System
+- ICMP - Internet Control Message Protocol
+- MAC - Media Access Control
+- NIC - Network Interface Controller
+- NFVi - Network Functions Virtualization infrastructure
+- SSH - Secure Shell
+- TCP - Transmission Control Protocol
+- VIM - Virtual Infrastructure Manager
+- VM - Virtual Machine
+
+System Under Test (SUT)
+=======================
+
+The system under test is assumed to be the NFVi and VIM in operation on a
+Pharos compliant infrastructure.
+
+Test Area Structure
+===================
+
+The test area is structured based on dynamic network runtime operations. Each
+test case is able to run independently, i.e. irrelevant of the state created by
+a previous test. Specifically, every test performs clean-up operations which
+return the system to the same state as before the test.

+
+Pass / fail criteria
+''''''''''''''''''''
+
+This test evaluates the functionality of basic network operations.
+Specifically, the test verifies that:
+
+* The Tempest host can ping VM's IP address. This implies, but does not
+  guarantee (see the ssh check that follows), that the VM has been assigned the
+  correct IP address and has connectivity to the Tempest host.
+
+* The Tempest host can perform key-based authentication to an ssh server hosted
+  at VM's IP address. This check guarantees that the IP address is associated
+  with the target VM.
+
+* The Tempest host can ssh into the VM via the IP address and successfully ping
+  the internal gateway address, implying connectivity to another VM on the same network.
+
+* The Tempest host can ssh into the VM via the IP address and successfully ping
+  the default gateway, implying external connectivity.
+
+* Detach the floating-ip from the VM and VM becomes unreachable.
+
+* Associate attached floating ip to a new VM and the new VM is reachable.
+
+* Floating IP status is updated correctly after each change.
+
+In order to pass this test, all test assertions listed in the test execution above need to pass.
