Abstract

The advent of Programming Protocol-independent Packet Processors (P4) enables the programmability of data planes, which provides not only further flexibility but also the possibility of the emergence of new features. With programmable data planes, network monitoring functionalities can be evolved beyond the conventional mechanism of Software-Defined Networks (SDN) which is polling-based monitoring based on OpenFlow. Although the polling-based method is easy and simple to collect monitoring information, it can cause substantial monitoring overhead on both the controller side and the switch side. Unlike the OpenFlow-based SDN which has one option to collect pre-defined information using the polling-based method, monitoring performance can be improved by applying new monitoring approaches based on P4. In this paper, a novel mechanism referred to as P4-based Proactive Monitoring (PPM) is proposed in order to enhance the efficiency of monitoring collection operations. PPM scheme adopts a proactive approach which allows programmable switches to proactively forward monitoring information to the controller after the controller enables PPM. The measurement results show that PPM can not only enhance the efficiency of collecting monitoring information by applying a proactive mechanism but also minimize the general monitoring overhead compared to the polling-based method.

软件定义网络中基于 P4 的主动监控方案

独立于编程协议的数据包处理器（P4）的出现实现了数据平面的可编程性，这不仅提供了进一步的灵活性，也为新功能的出现提供了可能性。有了可编程数据平面，网络监控功能就可以超越软件定义网络（SDN）的传统机制，即基于 OpenFlow 的轮询式监控。虽然基于轮询的方法可以轻松简单地收集监控信息，但会给控制器端和交换机端带来巨大的监控开销。与基于 OpenFlow 的 SDN 不同，SDN 只能选择使用基于轮询的方法来收集预定义信息，而基于 P4 的新监控方法则可以提高监控性能。本文提出了一种称为基于 P4 的主动监控（PPM）的新机制，以提高监控收集操作的效率。PPM 方案采用主动方法，允许可编程交换机在控制器启用 PPM 后主动向控制器发送监控信息。测量结果表明，与基于轮询的方法相比，PPM 不仅能通过应用主动机制提高监控信息的收集效率，还能最大限度地减少一般监控开销。
