Network-wide Packet Behavior Identification and Private Network Function Outsourcing

TL;DR

This paper introduces AP Classifier, a control plane tool that rapidly identifies packet forwarding behaviors across networks, supporting real-time updates with minimal memory, and proposes a secure network function outsourcing framework.

Contribution

The paper presents AP Classifier, a novel, high-speed, memory-efficient tool for network-wide packet behavior identification and a secure network function outsourcing framework.

Findings

AP Classifier is at least ten times faster than existing tools.

It uses very small memory, enabling real-time updates.

Supports secure network function outsourcing.

Abstract

Identifying the network-wide forwarding behaviors of a packet is essential for many network management applications. We present AP Classifier, a control plane tool for packet be- havior identification. Experiments show that the processing speed of AP Classifier is faster than existing tools by at least an order of magnitude. Furthermore, AP Classifier uses very small memory and is able to support real-time updates. We also present a network function outsource framework with AP Classifier which can provide security properties.
