[Re] Ensuring Connectivity via Data Plane Mechanisms

Abstract

The connectivity is of paramount importance to a network, whose basic function is to route packets between end points. Junda Liu et al. proposed Data‐Driven Connectivity (DDC) to ensure routing connectivity via data plane mechanisms, which allows networks to provide a much higher degree of availability, while still providing flexible routing control [1]. Nowadays, against the backdrop of the development of P4, Programming Protocol‐independent Packet Processors (a domain‐specific language) [2], one can enable the programmabilitiy of network devices to perform simple but extremely fast packet processing directly in the data plane. This article is a replication work of [1] within P4 ecosystem. Specifically, we implement DDC to the behavioral model version 2 (BMv2), a P4‐based and vastly used software switch. We evaluate our implementation against several benchmarks from the original paper, and we find that our results essentially align with the original work.
