The :term:`VNFC` contains -both the Traffic Inspection module, and the Traffic forwarding module, needed -to run the :term:`VNF`. The exploitation of Deep Packet Inspection -(: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 Packet Based per Flow State (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. Type of Service - (: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`/Differentiated Services Code Point (:term:`DSCP`) -multimedia traffic for Quality of Service (: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. - -Graphical Overview -================== - -.. code-block:: console - - +----------------------------+ - | | - | Virtual Traffic Classifier | - | | - | Analysing/Forwarding | - | ------------> | - | ethA ethB | - | | - +----------------------------+ - | ^ - | | - v | - +----------------------------+ - | | - | Virtual Switch | - | | - +----------------------------+ - -Install -======= - -run the vTC/build.sh with root privileges - -Run -=== - -:: - - sudo ./pfbridge -a eth1 -b eth2 - - -.. note:: Virtual Traffic Classifier is not support in OPNFV Danube release. - - -Development Environment -======================= - -Ubuntu 14.04 Ubuntu 16.04 diff --git a/docs/testing/user/userguide/15-list-of-tcs.rst b/docs/testing/user/userguide/15-list-of-tcs.rst index 37ce819f1..0efecebd1 100644 --- a/docs/testing/user/userguide/15-list-of-tcs.rst +++ b/docs/testing/user/userguide/15-list-of-tcs.rst @@ -17,8 +17,7 @@ Yardstick test cases are divided in two main categories: described in :doc:`02-methodology` * *OPNFV Feature Test Cases* - Test Cases developed to verify one or more - aspect of a feature delivered by an OPNFV Project, including the test cases - developed for the :term:`VTC`. + aspect of a feature delivered by an OPNFV Project.
