Discovery and capabilities of guard proxies for CoRE networks

TL;DR

This paper explores the design and capabilities of guard proxies in CoRE networks, focusing on their discovery, levels of intrusiveness, and effectiveness in mitigating undesired traffic to protect constrained resources.

Contribution

It introduces the concept of guard proxies in CoRE networks, analyzing their levels of intrusiveness, discovery methods, and potential to mitigate traffic-related resource exhaustion.

Findings

Proxies can be installed at network entry points without centralized management.

Different levels of proxy intrusiveness offer varying mitigation capabilities.

Proxies can effectively reduce undesired traffic in constrained environments.

Abstract

Constrained RESTful Environments tolerate and even benefit from proxy services. We explore the concept of proxies installed at entry points to constrained networks without any unified management. We sketch proxies of different levels of intrusiveness into applications, their announcement and discovery, and compare their theoretical capabilities in mitigating the effects of undesired traffic that can otherwise exhaust the environment's constrained resources.
