TL;DR

This paper introduces a gossip-based extension to the GIST protocol for improved signaling dissemination within networks, featuring bootstrap and service procedures, and three dissemination models tested on GENI.

Contribution

It presents a novel gossip-based dissemination extension for GIST, enabling flexible signaling message distribution with three distinct models.

Findings

The proposed method effectively disseminates signaling messages in testbed experiments.

The three dissemination models suit different network management scenarios.

Experimental results validate the approach's efficiency and practicality.

Abstract

In this paper, we propose a new gossip-based signaling dissemination method for the Next Steps in Signaling protocol family. In more detail, we propose to extend the General Internet Signaling Transport (GIST) protocol, so as to leverage these new dissemination capabilities from all NSIS Signaling Layer Protocol applications using its transport capabilities. The new GIST extension consists of two main procedures: a bootstrap procedure, during which new GIST-enabled nodes discover each other, and a service dissemination procedure, which is used to effectively disseminate signaling messages within an Autonomous System. To this aim, we defined three dissemination models, bubble, balloon, and hose, so as to fulfill requirements of different network and/or service management scenarios. An experimental campaign carried out on the GENI testbed shows the effectiveness of the proposed solution.
