SiNett
Unifies Wireless and Wired Switching
This week, SiNett announced its first products, the OneEdge family
of Ethernet switch chips. The OneEdge chips are the industry’s
first merchant products designed specifically for unified switching,
the term for a converged network that supports wireless LAN switching
in addition to traditional wired Ethernet. SiNett’s goal
is not to make dedicated WLAN switches cheaper but rather to
help unified switching become cost effective. The startup’s
CEO and CTO have a track record in Ethernet switching dating
back to Maverick Networks, where the two developed what would
become Broadcom’s highly successful StrataSwitch.
SiNett’s flagship SN5024 is a 24xFE plus 4xGbE Layer 3
switch with integrated encryption engines and customer-programmable
packet processors. On the switch side, the chip supports all
the newest Layer 2 protocols as well as IPv4 forwarding but not
IPv6 forwarding. The SN5024 has enough encryption throughput
for wire speed L2 (802.11i) or L3 (IPSec) security using AES.
A unified switch may need to perform L2 encryption when connecting
a “thin” WLAN access point, while L3 VPNs provide
an added layer of protection when using older WLAN security standards
such as WEP or WPA.
Although the switch side of the SN5024 handles Ethernet L2
and IPv4 L3 packet processing, the chip also includes four
32-bit
MIPS cores. These CPUs use DMA to transfer packets into and
out of the data path via four virtual switch ports. Together,
the
four CPUs deliver a healthy 1,000MIPS of peak processing
power.
In addition to the SN5024, SiNett will offer a 4xGbE version
(SN6004) intended for WLAN appliance and service-card applications.
Product samples along with a software developer’s kit are
due in March 2005. The company has not disclosed other details
such as power, package, or pricing.
The OneEdge
products offer a unique level of integration and should deliver
a powerful combination
of features and performance. If SiNett can price the
SN5024 at a modest premium over 24+2 switch chips (e.g., $50),
the startup
should see strong interest from more than just WLAN-switch
designers. At Ethernet-switch prices, the flexible chip is likely
to find
its way into many applications that SiNett has not even
considered. —BW
Cortina
Acquires Last TM Startup
RPR startup Cortina has acquired the assets of traffic-management
startup Azanda, including its products, customers, and about 18
engineers. Azanda began life developing an OC-768 traffic manager,
but when the higher-speed market failed to take off, it wisely
retargeted to an OC-48 TM. Consuming more than $40 million in funding,
Azanda had taken its TM chip to production and won designs at several
Tier One customers, including Cisco. In many of these designs,
Azanda's chip was used as a SAR between IP and ATM traffic. But
revenue from these designs wins was delayed and ultimately failed
to meet expectations.
Founded
in 4Q01, Cortina has raised more than $50 million and has a staff
of around 65 employees. In 2004, Cortina qualified
production
on its RPR chipset, which includes an RPR MAC, Ethernet MAC,
and serdes technology for connecting directly to an optical
module.
Cortina and Azanda shared a common set of customers, including
Cisco. Although
Cortina has generated some revenue, its design wins are not expected
to enter volume production until later
this year. Realizing a broad product line is needed for
a viable supplier,
several OEMs encouraged a merger between the two startups.
The cost of the acquisition was not disclosed, but we expect
it was
less than $5 million. With the demise of Azanda, no startups
remain that focus solely on traffic management.
With
a focus on the front end of a line card, Cortina plans to offer
several new products later this year.
Instead of a single
product, Cortina can now offer a set of product lines that
include SAR/TM, RPR MACs, and EoS products. With some
existing vendors
defocusing from framer/MAC components, Cortina has established
a position to build a sustainable company. —JB

News In Brief
Last
week, Chelsio announced second-generation
10GbE NIC and iSCSI HBA products. Based on the company's new
Terminator 2 chip,
the board-level products reduce cost and power dissipation
compared with the prior generation. Chelsio is offering a 10GbE
TOE NIC (T210) priced at $1,995 in volume and a 10GbE standard
NIC (N210) priced at $1,295. New to the company's lineup is
a 4xGbE TOE NIC (T204) priced at $895. Defending its first-to-market
position in 10GbE TOE, Chelsio intends to halve the price of
its NICs every 12 months. —BW

coverage of Chelsio's products appears in our new report A
Guide to Gigabit and 10G Ethernet Silicon.
This
week, Sandburst announced that it had raised
another $15 million funding, led by NeoCarta Ventures and including
all
earlier investors.
The startup has now raised a total of $72 million. Sandburst
offers a complete packet-switching solution, consisting of
a network processor
and a switch fabric with integrated traffic management. It
has design wins at HP, Enterasys, and other major OEMs. The
newest
funding rewards its success in product development and in winning
customers. —JB
Complete
coverage of Sandburst appears in our recent report A
Guide to Network Processors and also A
Guide to Switch Fabrics.
Last
week, Mindspeed upgraded the capabilities of
its TSP3 traffic managers with a firmware release, called BroadbandMaker,
targeting
triple-play access applications. Building on the fine-grained
traffic management capabilities of Mindspeed's TSP3 hardware,
BroadbandMaker
enables mixing of voice, video, and data in IP multicast
bandwidth-expansion environments. Running BroadbandMaker,
Mindspeed's M27481 traffic
manager provides more than 2Gbps throughput for IP-to-ATM
interworking, ATM cell switching, and IP multicasting while
prioritizing
delivery of real-time flows such as audio and video. —SI
