Architecture for All-Pervasive Home and Building Networking Based On UPnP - Sreejith - 08-16-2017 [attachment=3239] Architecture for All-Pervasive Home and Building Networking Based On UPnP Presented By Abhishek E.S. Anand Bhatia 1. All-Pervasive Connectivity- Everything, Everywhere 2.PnP-Plug And Play Ease Of Use- As the name suggests, Plug And Play, Eliminating User Hassles Ready2Go- All PnP devices: Just Connect and You Are Up and Running! Current Scenario.. Typical Homes of Today have a plethora of electronic devices, for eg: A TV A Computer A DVD Player A Mobile Phone A Portable Media Player(iPOD etc) A Temperature Regulating System Common thread among all these devices their embedded nature. Many have the ability to network, BUT NOT AUTOMATICALLY! Potential for Application Non-PC devices (4 billion embedded microprocessors in 1999) Rapidly increasing Internet adoption rates Strong uptake in Internet broadband deployments 64% of U.S. PC homes have television and PC in the same room 34% of U.S. PC homes have 2 or more computers By 2004 27MM networks installed 48.5MM nodes / year run rate Services a $3BB / yr business AGENDA The Dream Easy Home Networking THE What Of UPnP--THE CONCEPT THE WHY of UPnP--ADVANTAGES THE HOW of UPnP WORKING OBSTACLES TO IMPLEMENTATION PROPOSED OPTIMIZATIONS THE WAY AHEAD A Connected Environment THE WHAT-- UPnP UPnP stands for Universal Plug And Play A set of communication protocols that provides INVISIBLE home networking Framework for SELF-Configuring, SELF-Describing devices Salient Features Leverages existing Internet technologies such as TCP/IP, XML,UDP and HTTP Affordable, mainstream reality for users UPnP Strategy Just send data over the network No executables Minimize version issues Minimize security issues Allows implementation to be platform & vendor specific Be agnostic with reference to programming language, OS Update implementation without affecting interoperability. Improve performance Improve capabilities End User Benefits No need to install or share printer on the PC or and manually connect all devices to the network (no networking knowledge needed) Automatically discover printer/scanner and no need to search for new imaging devices added to the network. Benefits of UPnP Widely supported networking specification. No device configuration, just Plug and Play. Small footprint software component on the device. Utilizes standard Internet protocols to talk to LAN. Independent of OS, language, or physical connectivity. Robust and dependable. UPnP has advantages for developers and consumers alike. Drawbacks Network access . Large network sizes. High bandwidth actions. Users, access rights and security. Lack of sophisticated user interfaces. Absence of smart services across devices and networks. Optimizations Addition of a control server to isolate multicast traffic to local network. Improved search methodologies. Concept of user and session. Specific authorization procedures for authorization of control points and devices. Customized UI based on user profile Easy to understand for end consumer. Development of mobile device browsers to support delivery of web pages over presentation link. Provision of sophisticated multi-faceted services. Introduction of a services server to manage the services. Introduction of a UPnP IPv4/IPv6 bridge to support inter-operability. Bridge converts IPv4 addresses to IPv6 vice-versa. Different messages are relayed to the devices after IP address conversion by the bridge. The Way Ahead . Standardization , the lack of which , proved to be a major roadblock for connected homes was eliminated by the publication of the UPnP standard. AV media servers are some of the early beneficiaries of UPnP seamless connectivity. UPnP protocol stack needs to ported to other devices to ensure wider acceptance. |
