XMPP Overlay (XO) Messaging Framework 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. CAPABILITIES • Enable chat in infrastructure-less, constrained networked environments. • Compatible with common XMPP chat clients (Pidgin, iMessage, Adium) • Federate with legacy and enterprise XMPP chat servers • Cross platform (Windows, Mac OS, Linux, Android OS) • Instant messaging resilient to short-term network disconnects • Voice and Video KEY CUSTOMERS • Naval Research Laboratory CONTACT/ADDRESS DETAILS Duc Nguyen [email protected] Applied Informatics Group The College of Computing & Informatics, Drexel University [email protected] • drexel.edu/cci/aig XMPP Overlay Service (XO) PRODUCT CAPABILITIES XMPP Overlay Service (XO) provides serverless chat capabilities for mobile users in environments where backhaul links and enterprise networks are • Enable chat in infrastructure-less, constrained networked environments. unreliable or unavailable. • Compatible with common XMPP chat clients (Pidgin, iMessage, Adium) • Federate with legacy and enterprise XMPP chat servers • Cross platform (Windows, Mac OS, Linux, Android OS) • Instant messaging resilient to short-term network disconnects • Voice and Video KEY CUSTOMERS CONTACT/ADDRESS DETAILS • Naval Research Laboratory Duc Nguyen [email protected] Applied Informatics Group • The College of Computing & Informatics, Drexel University • [email protected] • drexel.edu/cci/aig.

    Online Instant Messaging: Keeping Your Child Safe and Secure Presented by: Meredith Stannard, Nauset Regional High School [email protected] Barbara Dominic, Nauset Regional Middle School [email protected] Kathy Schrock, Nauset Public Schools [email protected] Spring 2003 1 Instant messages are lasting ©2001. USA Today. http://www.usatoday.com/tech/news/2001-06-21-teens-im-lasting.htm By Karen Thomas, USA TODAY Breaking up. Making up. Making plans. Asking out. Saying "hey." From the mundane to the emotionally charged, there are no limits to the ways today's kids connect and bond over instant messages (IMs) — those pop-up text windows used for carrying on real-time conversations online. "It's not just empty chatter. They're using (IMs) to have difficult conversations — someone's talking behind your back and you want to confront them," says Amanda Lenhart of the Pew Internet & American Life project. Its survey, out Thursday, finds that nearly three-fourths of online kids ages 12 to 17 rely on IMs to keep in touch with friends. Caroline Barker, 16, is among 35% of teens who use IMs daily; she chats with about 10 close friends and 50 acquaintances in the Bethesda, Md., area. "It's especially good for making plans, or if you're just bored," she says. "It's a given that everybody has it," adds her friend Valerie Hutchins, 15. These Maryland friends IM while doing homework, talking on the phone and watching TV. And they offer insight to the complex social rules that come with a form of communication that still has many adults bewildered.

While RCS messages are already a big security improvement over SMS/MMS, we wanted to take it a step further and add end-to-end encryption (E2EE) to Messages, so no one else – including 2 Messages E2EE Overview​ Google servers or third-party servers – can access your conversations as they travel between your phone and the phone you message. Background & RCS Ecosystem RCS uses a set of standard internet protocols like Session Initiation Protocol (SIP)​[1] ​ to establish a connection between two clients through a central messaging server. This connection is then used to exchange the messages using Message Session Relay Protocol (MSRP)​[2].​ In some RCS deployments this server is hosted by the carrier, and in other deployments the server is hosted by Jibe Mobile from Google.
