Description

The uDPI (Universal Deep Packet Inspection) project is a reference framework to build a high performance solution for Deep Packet Inspection, integrated with the general purpose FD.io VPP stack. It leverages industry regex matching library to provide a rich set of features, which can be used in IPS/IDS, Web Firewall and similar applications.

The initial code contributions are from Intel and Travelping.

Overview of the uDPI reference framework: https://wiki.fd.io/view/File:Reference.png

Scope

uDPI's main responsibility is to provide a reference framework for Deep Packet Inspection. It will cover below key components:

• Flow Classification
  • HW flow offloading leveraging rte_flow on DPDK
  • SW flow classification
  • Supports both ipv4 and ipv6 flows
  • Supports Tunnel Traffic Classification
  • BD-aware and VRF-aware
  • Bi-directional traffic maps to one flow.

• Flow Expiration
  • Timer-based expiration mechanism
  • TCP session aware expiration mechanism

• TCP Segments Reassembly
  • TCP connection track
  • TCP segments re-ordering
  • TCP segments overlap handling

• Application Database
  • Default static Application Database
  • Add new Application rules dynamically

• Application Detection
  • Leverage Hyperscan Stream Mode
  • Reassembly TCP segments on the fly

• Application-based Actions
  • Qos
  • Rate Limiting
  • Policy Routing
  • SDWAN

• Supported Protocols:
  • TLS/HTTPS
  • HTTP
  • DNS
  • QUIC
