CABLELABS
CERTIFIES THE FIRST TWO DOCSIS
1.1 CABLE MODEMS
CableLabs awarded the first two certifications for DOCSIS
1.1 compliant cable modems to products from Toshiba and Texas
Instruments. Two
companies, Arris and Cadant, gained qualification status for their
DOCSIS
1.1 cable modem termination systems (CMTS).
By supporting tiered levels of traffic, the DOCSIS 1.1
standard is expected to open the door for advanced cable services,
including integration with home networking (the CableHome
project), packet telephony and multimedia offerings.

CableLabs,
September 27, 2001
- Last
month, CableLabs outlined the technical roadmap for DOCSIS
2.0, which would use advanced physical layer modulation
techniques to boost upstream bandwidth capabilities to as much
as 30 Mbps per 6 MHz channel without requiring any physical
rebuilding of cable networks. Specifically, DOCSIS 2.0
will incorporate S-CDMA (synchronous code division multiple
access) and A-TDMA (advanced frequency agile time division
multiple access) modulation to increase upstream capabilities.
The current DOCSIS 1.0 provides about 5 Mbps upstream per 6
MHz channel, while DOCSIS 1.1 provides 10 Mbps upstream.
CableLabs believes work on DOCSIS 2.0 can be completed this
year.
- In July, CableLabs made public
an interim specification and an architectural report for its
CableHome project, which aims to extend advanced network
services from DOCSIS cable modems to PCs and other devices
inside the home. Specifically, the CableHome QoS
specification defines a standard signaling and management
mechanism for applications to establish and maintain service
sessions with different levels of quality across the home
network and cable network.
CIDRA
LEVERAGES TI’S
DIGITAL LIGHT PROCESSING FOR OPTICAL COMPONENTS
CiDRA
is demonstrating the first optical networking product to
feature Texas Instruments’ Digital Light Processing (DLP)
technology. CiDRA's
AgileWave Dynamic Spectral Equalizer is a programmable filter that
can operate with spectral resolutions suitable for tilt, profile,
band or channel-by-channel gain/power-level balancing.
TI’s DLP techDigital Micromirror Device chip is an array
of up to 1,310,000 hinged, microscopic mirrors that operate as
optical switches. The
technology has been widely used almost exclusively in projection
and display applications. Since
early 1996, TI has shipped over 750,000 DLP subsystems to the
projector industry. http://www.cidra.com./news/pr_09272001.html

CiDRA, September 27, 2001
- In March, CiDRA
introduced a digitally programmable filter module that
enables precise routing and monitoring of individual DWDM
channels in optical networks.
The 50GHz tunable filter can scan or set to any
wavelength within the entire C-band using a digital command.
The device could be used as a monitoring and
transmission diagnostic tool by network operators for
verifying system performance for installation and maintenance
applications.
- In June 2000, CiDRA raised $100
million in venture financing to ramp-up its manufacturing
capacity as well as accelerate its product development
activities. Since
its founding in 1996, CiDRA has raised a total of $152
million. Investors
include Amerindo Investment Advisors, HRLD Ventures, Optical
Capital Group, First Reserve, Cisco Systems, MSD Capital,
Scudder Technology Fund; Putnam Investment; Morgan Stanley
Dean Witter; Infosys Technologies Limited, Connecticut
Innovations, Inc., and Teknoinvest.
CEREVA
CLOSES $51 MILLION IN FIFTH ROUND FUNDING FOR SCALABLE STORAGE
PLATFORM
Cereva Networks,
a start-up based in Marlborough, Massachusetts, secured
approximately $51 million in fifth round venture funding.
Cereva is developing a storage system designed for Internet
data centers. The
product will combine massive data scalability with SAN,
native HTTP, FTP, streaming media, and other content-distribution
capabilities. Participating investors in the
round include Matrix Partners, North Bridge Venture Partners, Oak
Investment Partners, Goldman Sachs, Intel, Worldview Technology
Partners and Sumitomo. http://www.cereva.com/news/pr_092601.html
Cereva Networks, September 27, 2001
- Key features of the Cereva
platform are expected to include shared
virtualized "pools" of storage that do not require
software on servers or appliances allowing the addition or
subtraction of storage and server connections, detailed
accounting and XML billing support, and massive incremental
scale to support millions of subscribers and thousands of
terabytes.
- Cereva is headed by Mahesh
N. Ganmukhi, who previously served as vice president and
general manager of ISTN at Lucent.
Prior to Lucent, he was the founder, president and CEO
of Ignitus Communications, which was acquired by Lucent in
April of 2000.
CORONA
RAISES $40 MILLION FOR IP SERVICE PLATFORM
Corona Networks,
a start-up based in Milpitas, California, closed $40 million in
third round funding, bringing its total capital raised to date to
over $68 million. The
company is developing a carrier IP service platform for delivering
VPNs, firewalls and NAT, as well as content-aware policy
capabilities. Interfaces
will range from DS-3 to OC-192, supporting thousands of virtual
routers and policies and hundreds of thousands of subscribers.
Investors include Merrill Lynch Ventures, New Enterprise
Associates, The Ignite Group, Alliance Ventures and Redwood
Ventures. http://www.coronanetworks.com/news/news_main_frameset.html
Corona Networks, September 27, 2001
- Corona Networks is headed by
Ramandeep Singh, who previously held various
positions in Product Management, Marketing and Engineering at
Nortel, Bay Networks, VLSI Technology and LSI Logic.
- Corona
Networks’ forthcoming ISP 12000 will provide physical or
logical terminations for various access technologies, such as
xDSL, ATM, leased line, cable modem, and wireless. It will
connect with optical backbone switches using ATM and
Packet-Over-SONET (POS).
The system is being designed to support more than 1.5
million simultaneous subscribers in a 16-slot chassis, or more
than 3 million per standard 7 foot rack.
Its core switch fabric will provide 256 Gbps
non-blocking data plane bandwidth.
CYNETA
NETWORKS TARGETS TCP EFFICIENCY IN WIRELESS DATA NETWORKS
Cyneta
Networks, a start-up based in Plano, Texas, announced its entrance
into the market for wireless data networking equipment.
Cyneta is developing a new network element called a
resource aware adaptive switch for optimizing IP traffic over
wireless infrastructures. The
executive team at Cyneta includes Doug Smith (CEO), formerly
president of Broadband Networks (acquired by Nortel Networks);
Jogen Pathak (CTO), formerly an architect of Nortel’s GPRS and
fixed wireless product lines; Dr. Janet Lind (VP of Engineering),
formerly Nortel Networks’ vice president of wireless Internet
development; and Shridhar Krishnamurthy, formerly founder of
MobileTop, a wireless content developer.

Cyneta Networks, September 27, 2001
- Cyneta’s
Adaptive Switching technology is being developed to address
problems such as frequent time-outs that occur when TCP
content is transmitted over a wireless network.
Its solution would evaluate
individual IP packets being transported across a wireless
network in order to determine if they are original or
retransmitted. It
would then forward the packet through to its destination,
modify or drop the packet (or session), or suspend/reschedule
the packet (or session).
The Cyneta platform would adapt
the TCP content for each user, based on the resources
requested and the unique characteristics of the cell
site/sector they are in at any point in time.
CLARENT
ANOUNCES REVENUE SHORTFALLS, 50% LAYOFFS
Clarent, a
provider of packet voice solutions, expects Q3 revenue to be in
the $17 to $18 million range, compared to earlier forecasts of $40
to $43 million. The
company is reducing its workforce worldwide by approximately 50%,
or around 350 employees. Clarent
also divulged further details of its previously announced material
overstatement of historical revenues.
Jerry Chang, the company's Chief Strategist, has resigned.
In addition, the company has terminated Matthew Chiang,
President of Clarent's Asia Pacific Region and Kevin Chang,
General Manager of Clarent's Northern Asia Operations.
All three executives previously had been placed on
administrative leave. http://www.clarent.com
