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.
