EMPOWERTEL
NETWORKS INTRODUCES ITS CONVERGENCE PROCESSORS
empowerTel
Networks, a start-up based in Milpitas, California, introduced a
line of “convergence processors” for next generation
multiservice platforms, wireline and wireless gateways and media
servers. Target applications for the optimized processors
include high-capacity, low-latency Voice over Packet, Video over
Packet and TDM over Packet services. empowerTel’s
MediaXpress processors will integrate several core technologies on
a single chip, including several service-optimized hardware
accelerated engines, multiple embedded RISC processors, a
high-speed lookup engine, a 4-way non-blocking 4k x 2k embedded
time slot interchanger (TSI) for broadcast/multicast and quiet
code insertion, and a multi-master internal cross bar switch.
The accompanying MediaFlow software provides a open API designed
to allow network equipment vendors to support features such as TDM
switching, IP and UDP packet filtering and lookup, fast packet
classification and jitter buffer management. The design
specifications call for media conversion latencies in order of 1
ms, real-time sample sizes as low as 1 ms, real-time alarms and
monitoring, power dissipation as low as 5mW per channel, as well
as on-chip RTP/RTCP processing, MPLS and DiffServ tagging.
The processors interface to industry standard DSPs for voice and
video processing and offer additional interfaces for PCI, CT/H.110
and Fast Ethernet. empowerTel plans to offer three
convergence processors: the MXP1070 with up to 1024 channels
per processor, the MXP1050 with up to 512 channels per processor
and the MXP1020 with up to 256 channels per processor. The
first processors are currently sampling. http://www.empowertel.com

Networks has raised over $70 million in funding from Goldman
Sachs, Morgan Stanley Dean Witter, Sony Corporation, Anschutz
Investment Company, Battery Ventures, TeleSoft Partners,
InveStar Capital and others.

Networks is headed by Ajit Medhekar, who previously served as
co-founder, chairman and CEO of Lara Networks (see below).
- In June,
Cypress Semiconductor agreed to acquire Lara Networks, a
developer of silicon-based packet processing solutions for WAN
infrastructure equipment, for $225 million (predominantly in
cash). Lara offers a line of network search engines (NSEs)
and network co-processors that could be used in switches,
routers and multiservice gateways handling multiple protocols
up to OC-768 and including 10-Gigabit Ethernet. Lara
supplies custom co-processors for Cisco's Enterprise line of
networking equipment and also counts among its customers
Juniper Networks, Foundry Networks, Extreme Networks,
Ericsson, NEC and Fujitsu. Lara’s co-processors
perform very-high-speed, parallel database searches -- to
offload the complex routing table search function from network
processors. Lara’s network search engines currently
support up to one million table entries and perform 100
million look-ups per second.
DEUTSCHE
TELEKOM DEPLOYS RAD'S ATM-AWARE CUSTOMER EQUIPMENT
Deutsche
Telekom began deploying RAD Data Communications' ACE-50 ATM-aware
Network Termination Unit (NTU). The ACE-50 devices, which
were developed by RAD in cooperation with Deutsche Telekom, are
used to provide a demarcation point between the networks of the
customers, medium-sized and big enterprises and the Deutsche
Telekom ATM network. The compact devices enable the carrier
to guarantee QoS by monitoring cell flow at the customer premises,
as well as to monitor physical and ATM layer status information
for end-to-end network control. In-band management is
provided over dedicated ATM VCCs. Financial terms were not
disclosed. http://www.rad.co.il/whatsnew/headlin26.htm

NTT
COMMUNICATIONS TO OFFER GLOBAL IP SLAS, IP SECURITY GATEWAY
NTT
Communications published plans for a Service Level Agreement (SLA)
for its Global IP Network Service and announced plans to launch a
Global IP Security Gateway Service. The new SLAs cover
network availability, packet latency, packet loss and customer
notification timelines for its network in Japan, North America,
Europe, Asia/Pac and Oceania. The Global IP Security Gateway
Service would be provided to other ISPs to allow them to develop
international IPSec-based VPN services for corporate users. http://www.ntt.com/NEWS_RELEASE_E/news01/0010/1011.html

FCC
MODERNIZES ACCOUNTING AND REPORTING REQUIREMENTS
The FCC
streamlined and modified its accounting rules and its financial
and operating data reporting requirements for incumbent local
exchange carriers (LECs). The new accounting rules overhaul two
areas: 1) the FCC's accounting rules, known as Part 32 of the
Uniform System of Accounts (USOA), which largely prescribe how
incumbent LECs record and allocate their revenues and costs, and
2) the FCC's Automated Reporting Management Information System (ARMIS)
reporting rules, which require certain carriers to report
financial and operating information on an annual basis. A summary
of all of the reform measures is online.

DATUM
TO USE VERISIGN DIGITAL CERTIFICATES FOR SECURE TIME STAMPING
SERVICE
Datum will
integrate VeriSign's digital certificate technology into its
secure StampServer service. The electronic time stamps are
aimed at providing irrefutable proof of the date and time a
document was signed or a transaction occurred. Datum said its time
stamps are recognized as secure for two reasons: first, the time
is traceable to an official universal coordinated time (UTC) time
source, and second, the authenticity of the time is secured by the
same technology that protects the authenticity of the digital
signature itself. Datum StampServer customers use on-premises time
stamp servers supplied by Datum's Trusted Time Division. Under
this agreement, those servers will in effect become
"VeriSign-enabled." http://www.datum.com/10-11-01.html

What is GMPLS?
A Unified Vision for Carrier Networks

The challenge is known.
Now, more than ever, profitability depends on improved return on
investment (ROI). For telecommunications service providers, ROI is
inseparable from efficient use of network resources. This means
that the service providers who will emerge as winners from the
current economic downturn are those that deploy the most efficient
and cost-effective network infrastructures. Generalized
Multi-Protocol Label Switching (G-MPLS) can help service providers
both reduce operational expenditures and increase the services
they offer to their customers.
G-MPLS
G-MPLS is a logical evolutionary
advance from IP through MPLS and MPLλS. With support from the
Internet Engineering Task Force (IETF) and the Optical
Internetworking Forum (OIF), it is fast becoming an industry
standard. Development of G-MPLS began with the premise that it is
possible to implement full integration of provisioning for all
traffic types. G-MPLS was thus developed with the goal of creating
a single suite of protocols that would be applicable to all
service and transport traffic.
G-MPLS brings the intelligence and
dynamic circuit (or path) provisioning of packet services to TDM
and wavelength services. Its extensions offer a common mechanism
for data forwarding, signaling and routing on transport networks.
G-MPLS thereby extends the MPLS label and LSP (Label Switched
Path) mechanisms to create Generalized Labels and Generalized LSPs.
These extensions affect routing and signaling protocols for
activities such as label distribution, traffic engineering, and
protection and restoration.
G-MPLS is in many ways analogous to
the labels used by next-day delivery services. A single type of
label is used for all packages and destinations. The same label is
used to get a letter, a parcel or a suitcase delivered across town
or across the ocean, and by the most appropriate means, be that
bicycle, truck or air freight. The single label guarantees speedy,
cost efficient delivery and can be read by the different
departments, such as sorting, routing and delivery.
Similarly, G-MPLS provides a labeling mechanism that can be used
to get all traffic types to its destination—packet, TDM and
wavelength. Thus, G-MPLS enables evolution to simpler, more
efficient network architectures.
G-MPLS can be deployed in a
traditional overlay network to bring IP intelligence to non-packet
traffic. The benefits of G-MPLS are most fully realized, however,
in a network where G-MPLS enables consolidation of the control
plane and extension of topology awareness and bandwidth management
across all network layers.
