-Reconfiguration of VNF Service Chains

+VNF Service Chains
+==================
-See :ref:`reconf_tests` for methodology description of this test type.
+.. important::
+
+ **DISCLAIMER**: Presented test results should be taken with a pinch of
+ salt as they may not represent correctly the system behaviour due
+ to experimental nature of used test methodology (see :ref:`reconf_tests`).
In each test, a single service chain is added, the re-configuration
contains all the steps the initial chains got, except the last step
Additional information about graph data:
-#. **Graph Title**: describes tested packet path including VNF workload
- running in each VM.
+#. **Graph Title**: describes tested VPP packet path. Format:
+
+ - wire encapsulation ``dot1qip4vlxan``,
+ - VPP forwarding mode ``l2bd``,
+ - total number {Y} of service chains ``{Y}ch``,
+ - total number of chains being reconfigured ``1ach``,
+ - total number of vhost-user interfaces forwarding packets on VPP with {Y}
+ chains and {X} VMs per chain ``{2XY}vh`` (2 interfaces per {X} VMs per {Y}
+ chains),
+ total number {XY} of VNF VMs forwarding packets ``{XY}vm`` and finally
+ - VNF workload in VM ``testpmd``.
