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. - -Graphical Overview -================== - -Install -======= - -run the build.sh with root privileges - -Run -=== - -sudo ./pfbridge -a eth1 -b eth2 - -Custom Image -============ - -TBD - -Development Environment -======================= - -Ubuntu 14.04 >= VM diff --git a/docs/vTC/abbreviations.rst b/docs/vTC/abbreviations.rst deleted file mode 100644 index a713ee66b..000000000 --- a/docs/vTC/abbreviations.rst +++ /dev/null @@ -1,5 +0,0 @@ -Abbreviations for the virtual Traffic Classifier -================================================ - -[1] VNF - Virtual Network Function -[2] VNFC - Virtual Network Function Component |
