  1. The Common-Interface-Based Residential Gateway(CIB-RG) Pusik Park, KiTaeg Lim, KwangHo Choi SoC Research Center Korea Electronics Technology Institute Email: {parksik, limkt, khchoi}@keti.re.kr

  2. Introduction • The Residential Gateway(RG) is at the heart of Home-area Networking Solution • Current Industry Status • Closed and Fixedarchitecture • Support only a few interfaces • Zero-Compatibility and Hard Expandability due to Non-standardization. • Standards for Residential Gateway • TIA’s TR-41.5 committee has attempted • ISO/IEC JTC 1/SC 25 developed the first specification of HomeGate in October 1998 • Benefits of RG’s Standardization • Reduced development and maintenance costs by using open architecture • Unlimited support of a lot of interfaces

  3. HomeGate of ISO/IEC JTC 1/SC 25 WG1

  4. Choice of Common Interfaces • Physical layer • PCMCIA interface • Thin, Small, Lightweight • A Neat Appearance without a Projection after card insertion • Network & Transfer layer • Ethernet & TCP/IP protocol suite • The best popular protocol deployed widely • Easy Implementation and Maintenance • Seamless Convergence with the broadband internet • Middleware • Embedded Linux • Universal Plug and Play • Simple, Easy implementation • Supporting the Bridge for a difference middleware

  5. The Common Middleware, UPnP

  6. The Common Protocol Stack

  7. The Open Hardware Architecture Blockdiagram of a GIP Processing Box Blockdiagram of a LGI/WGI

  8. Local Operation (0) All LGIs and a WGI advertise themselves as soon as “Power On”. (1) Found a LIGHTING device (2) Send the action, “TURN ON” (6) Receive the response, “OK” (7) Lighting status change “ON” (3) Receive the action, “TURN ON” (4) Turn on the light. (5) Send the response, “OK”

  9. Broadband Operation (1) Browse the My Home Page. (2) Select a device and click it (3) Show the Main Page for controlling the light (4) Click the button for turning on the light (7) Confirm status of the light (0) The GIP system collects information which LGIs and WGIs exist and builds the My Home Page (5) Receive the action, “Turn ON” (6) Send the response, “OK”

  10. Demonstration Left: LonWorks HomeAutomation Testbed Right: The set of the CIB-RG. TabletPC with WLAN (running UPnP Control Point, Connecting the WLAN LGI)

  11. Conclusion • Current closed RG platform has a lotof problems, hard upgrade, poor compatibility and so on • RG’s standardization activity is in progress but not active • We proposed the Common-Interface-Based Residential Gateway (GIB-RG) which defines the open hardware architecture, the common transfer protocols and middlewares • We demonstrated the CIB-RG system with WLAN LGI, LonWorks LGI and ADSL WGI • The common RG architecture has an advantage of easy implementation, maintenance and good compatibility.
