Real-Time Packet Traceback Based on Intent for Software-Defined Networks

Abstract— Tracing back packets intentionally is a sub-issue of packet traceback, which is useful for network debugging, network forensics and performance testing. However, current mechanisms for classifying packets with IP addresses, port numbers and other low-level features of Software-Defined Networking (SDN)flows, rather than with abstractions map to the intent, such as people, applications and devices. In this paper, we present the basic idea for intentional packet traceback that satisfies users’ intents or goals and a preliminary design and implementation that can work in a real-time environment. A significant improvement is designing an interface that defines an SDN controller as intent, and using the intent to collect packet as input variantfor computing back policy on the controller. We present an example that show how these goals can be achieved from modular component to iteratively traceback and discuss the real-time feature of our proposed.
