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.

• 20.01 Release Plan
