^^^^^^^^^^^^^^^^
This packet path represents a single service chain with 2 loopback VNFs in sequence and 3 Neutron networks.
-The 2 VNFs can run on the same compute node (PVVP intra-node):
+The 2 VNFs will only run on the same compute node (PVVP intra-node):

-or on different compute nodes (PVVP inter-node) based on a configuration option:

Multi-Chaining (N*PVP or N*PVVP)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This innovative feature will allow to measure easily the performance of a fully loaded compute node running multiple service chains.
-Multi-chaining is currently limited to 1 compute node (PVP or PVVP intra-node) or 2 compute nodes (for PVVP inter-node).
-The 2 edge interfaces for all service chains will share the same 2 networks.
+Multi-chaining is currently limited to 1 compute node (VMs run on the same compute node).
+The 2 edge interfaces for all service chains can either share the same 2 networks or can use
+dedicated networks (based on a configuration option).
The total traffic will be split equally across all chains.
Limitations
***********
NFVbench only supports VLAN with OpenStack.
-NFVbench does not support VxLAN overlays.
+VxLAN overlays is planned for a coming release.
