The document discusses challenges and visions for home networking. It describes how home networks could enable new applications like home information management services. However, widespread adoption faces challenges around ease of use, security, and reliability. Industry efforts aim to address these challenges through standards like CableHome, but more work is still needed to make home networks simple to install, use, and maintain.

Practicality Intrudes Vision: The presence of a home network will enable creation of many new applications and services Such as Home Information Management Services Reality: I encounter difficulty in simply adding devices and software to my home PC and in keeping the PC operating. Imagine life with a home network
The Real Topic of this Talk Challenges of making home networks easy to install, use and maintain Industry efforts to address this problem Our approach to these issues Home Information Management Services An application that addresses an emerging need and illustrates how we think Home Networks should behave
What is a Home Network? A “Home Network” connects consumer devices in the home to facilitate communications among the devices STB Fixed Wireless Wireless Adapter Wireless Home LAN Media Access Gateway Existing Telephone Wiring Internal HPNA Printer Adapter Indoor CM/BTI Voice Adapter Outdoor CM/BTI Fax Voice Adapter No Adapter
Some Home Network Application Drivers Technology advances make it practical Small, low cost storage and computation High bandwidth distribution Evolution of MAC/PHY standards for the home Wireless devices Economical device sharing and control Consolidation of display devices, and automation Migration to lower cost IP based services Voice, video and data The Internet Entertainment and multimedia Multi-player gaming, video on demand Services targeted to home consumers Messaging, backup, e-commerce, remote sensing
Rosy Predictions The home-networking equipment market is expected to grow from about $600 million this year to more than $5.7 billion by 2004 (Cahners In-Stat Group) More than 12 million U.S. homeowners want to implement home-networking capabilities within the next year (Yankee Group) Cahners In-Stat Group predicts annual sales of 30,000,000 residential gateway units for a total of $5 billion in 2005 But… Widespread adoption requires substantial improvements in ease of use, security, and robust operation

More Challenges Fault diagnosis and maintenance Detect failures and misconfiguration Robust Fault Tolerant Local effects only Self-stabilizing Deterministic Secure Always connected to Internet means new risks Control Access and operations on resources Quality of Service (QoS) Needed for applications that have minimum requirements on throughput, delay or delay variation for acceptable operation Video, gaming
Current Solutions May Not Always Apply A Home Network differs from an Enterprise Network Cost sensitivity IP address sharing leads to new problems Scale Many homes with few users in each Many simple, specialized devices per user No IT department

Observations on CableHome Designed from a cable provider viewpoint Aimed at delivering managed services from the MSO network to the home network Example: focuses on protecting MSO rather than home Architecture presumes a cable-modem based residential gateway Won’t help with your home network if you don’t have a CableHome compliant residential gateway Points to existing standards where applicable IP-based
