Internet Protocol IP and Gigabit Ethernet Technology for Home Networking: BroadBand Home Network BBH

1
Internet Protocol (IP) and Gigabit Ethernet
Technology for Home Networking BroadBand Home
Network (BBHN) Proposal

• ISO/IEC JTC1/SC25/WG1 N1173

• Brian Von Herzen, Ph.D.
• Xilinx Consultant

2
BroadBand Home Network

• Common network and backplane for voice, video and
  computer networking in the home
• Targets consumer applications in the home aiming
  for low cost.

3
Ethernet

• Speeds from 1 to 1000 Mbps
• Low-cost alternative
• Non-blocking switches enable unimpeded system
  throughput.

4
Ethernet non-blocking switch

• The typical consumer 8-port switch available
  today to consumers is non-blocking

1394a elements share bandwidth

• 1394a networks share 400 Mbps between them, since
  1394a hubs broadcast to all receipients.

Ethernet Speed Capabilities

• 10 Mbps
• 100 Mbps
• 1000 Mpbs
• All over common CAT5 wiring
• 10,000 Mbps backplanes and cables available

7
Computer networking

• Ethernet IP and Wi-Fi IEEE802.11 communications
  provide a majority of computer networks in the
  home.

8
Ethernet Video

• Several manufacturers have developed ethernet
  video cameras with direct RJ-45 connectors for
  CAT-5 cable.
• Examples
• D-Link DCS-900W
• Panasonic KX-HCM270
• QoS underway at IEEE 802.3ar
• Congestion Management

9
IEEE P802.3ar Congestion Management Task Force
Objectives

• Specify a mechanism to support the
• communication of congestion information
• Specify a mechanism to limit the rate of
• transmitted data on an Ethernet link
• Preserve the MAC/PLS service interfaces
• Minimize throughput reduction in non-congested
  flows

10
IEEE P802.3ar Congestion Management Task Force

• Designed to ensure Quality of Service over
  Ethernet networks
• Approved IEEE P802.3ar Project Authoriation

11
IEEE P802.3ap, Backplane Ethernet Task Force.

• 1 Gigabit backplane signaling
• 10 Gigabit/s backplane signaling effort already
  in IEEE balloting stage
• Leverage significant work in backplane ethernet
  standards

Recommendation

• Specify IP as the substrate for BBHN
• Implement Bonjour discovery and SSDP as a
  fallback.
• Illustrate reference implementations using Gb
  Ethernet and 1394 (and wireless and powerline)
• Provide high performance solutions at low cost
