Include vTC overview in Yardstick documentation
This change includes the vTC overview in Yardstick configguide, the original vTC/README has been renamed to 04-vTC-overview and added in the configguide. The vTC/abbreviations is deleted, all included in glossary.rst Index and 03-list-of-tcs are updated.

-Virtual Traffic Classifier
-==========================
-
-Overview
-========
-
-The virtual Traffic Classifier VNF [1], comprises in the current version of
-1 VNFC [2]. The VNFC contains both the Traffic Inspection module, and the
-Traffic forwarding module, needed to run the VNF. The exploitation of DPI
-methods for traffic classification is built around two basic assumptions:
-
-(i) third parties unaffiliated with either source or recipient are able to
-inspect each IP packet’s payload and
-(ii) the classifier knows the relevant syntax of each application’s packet
-payloads (protocol signatures, data patterns, etc.).
-
-The proposed DPI based approach will only use an indicative, small number of
-the initial packets from each flow in order to identify the content and not
-inspect each packet.
-
-In this respect it follows the Packet Based per Flow State (PBFS).
-This method uses a table to track each session based on the 5-tuples
-(src address,dest address,src port,dest port,transport protocol)
-that is maintained for each flow.
-
-Concepts
-========
-
-Traffic Inspection: The process of packet analysis and application
-identification of network traffic that passes through the vTC.
-
-Traffic Forwarding: The process of packet forwarding from an incoming
-network interface to a pre-defined outgoing network interface.
-
-Traffic Rule Application: The process of packet tagging, based on a
-predefined set of rules. Packet tagging may include e.g. ToS field
-modification.
-
-Architecture
-============
-
-The Traffic Inspection module is the most computationally intensive component
-of the VNF. It implements filtering and packet matching algorithms in order to
-support the enhanced traffic forwarding capability of the VNF. The component
-supports a flow table (exploiting hashing algorithms for fast indexing of
-flows) and an inspection engine for traffic classification.
-
-The implementation used for these experiments exploits the nDPI library.
-The packet capturing mechanism is implemented using libpcap. When the DPI
-engine identifies a new flow, the flow register is updated with the
-appropriate information and transmitted across the Traffic Forwarding module,
-which then applies any required policy updates.
-
-The Traffic Forwarding moudle is responsible for routing and packet forwarding.
-It accepts incoming network traffic, consults the flow table for classification
-information for each incoming flow and then applies pre-defined policies
-marking e.g. type of Service/Differentiated Services Code Point (TOS/DSCP)
-multimedia traffic for QoS enablement on the forwarded traffic.
-It is assumed that the traffic is forwarded using the default policy until it
-is identified and new policies are enforced.
-
-The expected response delay is considered to be negligible,as only a small
-number of packets are required to identify each flow.

+Additional documentation is available in TNOVAresults_.
+
+Overview

+
+The virtual Traffic Classifier :term:`VNF`, the :term:`VTC`, comprises of a
+:term:`VNFC`. The :term:`VNFC` contains both the Traffic Inspection module, and
+the Traffic forwarding module, needed to run the VNF. The exploitation of
+:term:`DPI` methods for traffic classification is built around two basic
+assumptions:
+
+* third parties unaffiliated with either source or recipient are able to
+inspect each IP packet’s payload
+
+* the classifier knows the relevant syntax of each application’s packet
+payloads (protocol signatures, data patterns, etc.).
+
+The proposed :term:`DPI` based approach will only use an indicative, small
+number of the initial packets from each flow in order to identify the content
+and not inspect each packet.
+
+In this respect it follows the :term:`PBFS`. This method uses a table to track
+each session based on the 5-tuples (src address, dest address, src port,dest
+port, transport protocol) that is maintained for each flow.
