Intro

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.

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 Segment Reassembly
    • TCP connection tracking
    • TCP segment re-ordering
    • TCP segment overlap handling
  • Application Database
    • Default static Application Database
    • Add new Application rules dynamically
  • Application Detection
    • Leverage Hyperscan Stream Mode
    • Reassembly of TCP segments on the fly
  • Application-based Actions
    • QoS
    • Rate Limiting
    • Policy Routing
    • SD-WAN
  • Supported Protocols:
    • TLS/HTTPS
    • HTTP
    • DNS
    • QUIC
    • etc.

Releases

UDPI releases are based on VPP version numbers.
