-This chapter provides an overview of the virtual Traffic Classifier, a
-contribution to OPNFV Yardstick_ from the EU Project TNOVA_.
-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.
-
-Concepts
-========
-
-* *Traffic Inspection*: The process of packet analysis and application
-identification of network traffic that passes through the :term:`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. :term:`ToS` field
-modification.
-
-Architecture
-============
-
-The Traffic Inspection module is the most computationally intensive component
-of the :term:`VNF`. It implements filtering and packet matching algorithms in
-order to support the enhanced traffic forwarding capability of the :term:`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
-:term:`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. :term:`ToS`/:term:`DSCP` multimedia traffic for :term:`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.
