Introduction
----------------
-Describing the components and behaviours in a manner that helps people understand the platform and how to work with it
+NFVbench is a python application that is designed to run in a compact and portable format inside a container and on production pods.
+As such it only uses open sourec software with minimal hardware requirements (just a NIC card that is DPDK compatible).
+Traffic generation is handled by TRex on 2 physical ports (2x10G or higher) forming traffic loops up to VNF level and following
+a path that is common to all NFV applications: external source to top of rack switch(es) to conpute node(s) to vswitch (if applicable)
+to VNF(s) and back.
+Configuration of benchmarks is through a hierarchy of yaml configuraton files and command line arguments.
+
+Results are available in different formats:
+- text output with tabular results
+- json result in file or in REST reply (most detailed)
+
+Logging is available in a log file.
+
+Benchmark results and logs can be optionally sent to one or more remote fluentd aggeregators using json format.
