XMPP Overlay (XO) Messaging Framework Overview XO (XMPP Overlay) is a serverless asynchronous messaging framework that provides group communications across tactical and enterprise networks. Problem Statement Messaging within mobile ad-hoc networks cannot rely on standard server-centric, TCP communications solutions. These are not suited to disconnected, intermittent, limited (DIL) networks, such as mobile ad-hoc networks. Our Approach The XO middleware is a cross-platform middleware framework that brings asynchronous, serverless group messaging that bridge tactical and enterprise environments. The XO middleware is proven to deliver more messages in dynamic networks than standard server-centric messaging solutions. Key Features • Utilizes and extends common communications standards (XMPP, NORM, SMF, mDNS) • Serverless, asynchronous messaging and service discovery • Proxy architecture allows users to run familiar XMPP clients (e.g.: Pidgin, Spark) • Gatewaying to XMPP servers (e.g. OpenFire) allows plugging into existing infrastructure • Semantic descriptors for publish and subscribe group communications • Supports both reliable and unreliable message delivery • Provides long-term persistent storage for DIL Networks Sponsored by Applied Informatics Group The College of Computing & Informatics, Drexel University [email protected] • drexel.edu/cci/aig XMPP Overlay Service (XO) PRODUCT XMPP Overlay Service (XO) provides serverless chat capabilities for mobile users in environments where backhaul links and enterprise networks are unreliable or unavailable.
