NETWORK
ELEMENTS ANNOUNCES 10 GBPS MODULE INTEGRATING OPTICS AND
MULTIPROTOCOL PROCESSING
Network
Elements, a start-up based in Beaverton, Oregon, announced a 10
Gbps optical networking module featuring integrated multi-protocol
processing for 10 Gigabit Ethernet, Packet-over-SONET (POS) and
SONET/SDH applications in the LAN, MAN and WAN. At the
center of Network Element's new module is a 2 million gate ASIC
that provides standard protocol processing, advanced packet
filtering for admission control and flow-based traffic monitoring,
built-in test stream generation, and support for both
next-generation and standardized SONET signaling. The
multi-protocol processor ASIC implements a 10GbE processor, POS
processor, SONET processor, statistics monitoring processor and
packet filter. The multiprotocol support allows it to be
used for a single line card design that could be provisioned by
the equipment manufacturer as required (10 GigE, 10 Gbps POS, or
10 Gbps SONET/SDH). API software provides an abstracted user
interface for the more complex features of the module, such as
SONET monitoring and packet filtering, automatically handling
functions such as counter, table and queue management. The
module is configured with 1310nm serial optics supporting 2km and
12km reaches. Network Elements said the high level of
integration of its lithium module could save six months in product
development time while offering reduced space, power, and cost.
The module is priced at $7,000 in quantity. http://www.nei.com

TI
INTRODUCES FAST DSP-SYNC FIRST-IN, FIRST-OUT (FIFO) DEVICES
Texas
Instruments introduced its fastest 3.3-V DSP-Sync First-In,
First-Out (FIFO) devices designed for high-bandwidth telecom and
internetworking applications. The products, which provide a
glueless interface with TI's DSPs, offer 3.0 Gbps data-rate
performance (166 MHz max clock cycle frequency) and data access
times of 4.5 ns. The new FIFOs could be used in
multi-channel applications that require buffering large amounts of
data, such as wireless base stations, remote access servers (RAS),
xDSL systems, network security camera systems, cable modems,
advanced medical/industrial imaging applications, precision
instrumentation, and multi-channel telephony systems. http://www.ti.com/sc/docs/news/2001/01154.htm

An
Introduction to MPLS

In this article, we will examine how an MPLS
network is constructed and how MPLS data flows. In future
articles, we will examine 1) How a switch receives its switching
instructions (signaling); 2) How MPLS interfaces with layer 2
switches (ATM and Frame Relay); 3) Traffic Engineering; and 4)
MPLS self-healing networks. In order to assist your further
study, I have provided an acronym list and a list of related URLs
to accompany each article.
INTRODUCTION
What is this
new protocol that leading telecommunication experts claim “will
take over the world”? Well, you can rest your worried mind
– IP and ATM are not on death row. In fact, it is my
belief that MPLS will breathe new life into the marriage of IP and
ATM.
The best way
to describe the function of MPLS is by using an analogy of a large
national firm with campuses located throughout the United States.
Each campus has a central mail-processing point through which mail
is sent around the world, as well as to its other campuses.
Since its beginning, the mailroom has been under orders to send
all intercampus correspondence via standard first-class mail.
The cost of this postage is calculated into the company’s
operational budget.
However, for
months now, some departments have been complaining that they
require overnight delivery and package-tracking services. As
a manager, you set up a system to send three levels of mail
between campuses – first class, priority, and express mail.
In order to offset the increased expense of the new services, you
bill the departments that use these premium services at the
regular USPS rate plus 10%.
Priority and
express mail are processed by placing the package into a special
envelope with a distinctive label. These special packets
with distinctive labels assure the package priority handling and
tracking capability within the postal network. In order to
avoid slowdowns and bottlenecks, the postal facilities in the
network created a system that uses sorting tables or sorting
databases to expedite these special packets.
The
Construction of an MPLS Network
In an IP
network, you can think of routers as post offices or postal
sorting stations. Without a means to mark, classify, and
monitor mail, there would be no way to process different classes
of mail. In IP networks, you find a similar situation.
