IS-2008-27: GridWise Architecture Council: Decision-Maker's Interoperability
Checklist Draft Version 1.0
This paper by the GridWise Architecture Council explains the importance of
interoperability in the system for generating, transporting, distributing, and using
electricity. Distinctions are made among Technical Interoperability (physical and
communications connections), Informational Interoperability (data content and meaning),
and Organizational Interoperability (business and legal relationships). Interoperability will
improve reliability, market operations, and will lower grid capital costs. The authors urge
that interoperability be factored into equipment design as the grid is upgraded. They
propose a checklist to determine if a proposed upgrade facilitates interoperability.
IS-2008-26: China Market, The Security Industry Association Report: Olympic
Update
This paper by the Security Industry Association describes the plans for security systems
at the August 2008 Beijing, China Olympic Games. There are 31 Olympic venues. The
business organizations involved and coordination are described. Expenditures on
security systems are estimated at $300 million for the Olympics. The equipment to be
used and suppliers are listed.
IS-2008-25: ROADMs in Network Architectures
This document by Ciena explains the functions of Reconfigurable Optical Add/Drop
Multiplexers (ROADMs) for enabling dynamic configuration of optical networks. ROADMs
are designed to support Dense Wavelength Division Multiplexing (DWDM). DWDM
supports multiple fiber optics channels of different wavelengths. ROADMs allows these
channels to be added, removed, or modified automatically. The technology of ROADMs
is explained.
IS-2008-24: Making the Case for Converged Ethernet Transport
This paper by Ciena explains that role of Ethernet for high-speed data transport outside
of a local area network. Internet traffic is predicted to grow at a 35 per cent-compound
rate between 2006 and 2012. Ethernet Internet Protocol traffic is expected to surpass
time division multiplexing traffic by 2009. Technologies for optical Ethernet switches are
discussed. Applications include triple play, business data services, and wireless backhaul
operations.
IS-2008-23: Evolution to the 100G Transport Network
The technologies to transport 100 Gbps Internet data are discussed in this report
authored by Ciena. Applications include video-on-demand and IPTV. Client connections
to the Internet backbone are now reaching 10 Gbps. The backbone operates at two to 10
times the highest-speed client. 100 Gbps is considered for data centers and metropolitan
and wide area network connectivity. Technologies for implementing 100 Gpbs using fiber
optics are discussed.
IS-2008-22: Final Report of the California Broadband Task Force - January 2008
This paper is a report to the government of California about broadband Internet
deployment in the state and policy proposals to increase availability. Benefits claimed
include telecommuting, video conferencing, distant-learning, remote medical analysis,
and increased civic discourse. Broadband is not widely available to rural locations where
three million people live in California. It was noted that broadband costs are up to four
times higher and one-tenth the speed than in other developed countries, such as a
Japan. The US ranks 16th in broadband adoption and California ranks 10th compared to
developed countries. The report recommends that high-speed broadband be available to
all Californians "with the lowest subsidy necessary" and with tax incentives.
