A Novel low-latency DBA for Virtualised PON implemented through P4 In-Network Processing

TL;DR

This paper introduces a P4-enabled in-network scheduler for virtualized PONs that significantly reduces upstream latency through a novel dual-DBA allocation method.

Contribution

It proposes a new low-latency DBA scheme implemented via P4 in-network processing, enhancing virtual PON performance.

Findings

Latency reduced by 37% compared to standard PON

Latency reduced by 43% compared to virtual PON

Demonstrates effectiveness of P4-based in-network scheduling

Abstract

We present a novel dual-DBA allocation, with a fast P4-enabled scheduler to provide low latency upstream grant allocations. We show latency reduction of 37% and 43%, respectively, compared to standard and virtual PONs
