RIVERSTONE DEBUTS MPLS OVER GIGABIT ETHERNET
Riverstone Networks introduced a new line-card architecture for its metro area products that provides MPLS capabilities over a Gigabit Ethernet interface.  Each line card uses a wire-speed, programmable packet-processing engine supporting full MPLS Label Edge Router (LER) and Label Switch Router (LSR) functionality, including label generation and forwarding at wire speed, up to 8,000 Label-Switched Paths (LSPs) per port, multi-level label stacking and Layer 2 tunneling capabilities.  The programmable design of the packet processors allows for future updates for VPN technologies such as Generic Routing Encapsulation (GRE) and IP-IP tunneling, ATM, and Frame Relay over MPLS.  http://www.riverstonenet.com/news/press/20010423.shtml

TI COMBINES DSPS WITH MEMS FOR 100 MBPS ETHERNET WIRELESS OPTICAL PLATFORM
Texas Instruments announced an optical wireless reference design that combines digital signal processors (DSP) and analog with MicroElectro-Mechanical Systems (MEMS) technology to deliver 100-Mbps Ethernet full-duplex, point-to-point secure communications over a range of 50 meters.  The design would offer a free-space alternative to category 5 cabling in corporate LANs.  Enabling technology consists of a two-axis, gimbaled MEMS mirror, a DSP that steers the mirror with precision to a fraction of a micron -- allowing switching speeds of less than five milliseconds (ms)n -- and high-speed data converters, operational amplifiers and power management ICs.  http://www.ti.com/sc/alp

ATRICA INTRODUCES ITS METRO OPTICAL ETHERNET PLATFORM
Atrica, a start-up based in Santa Clara, California, with R&D operations in Israel, introduced a 10 Gbps metro optical Ethernet solution that does not use SONET.  Atrica said distinguishing features of its platform include service-level guarantees, sub-second failure protection, integration with circuit-switched networks and service management that meets and exceeds what carriers have been accustomed to in SONET networks.  The product set includes:

• An Optical Ethernet Edge Switch offering a combination of Ethernet interfaces supporting a set of Ethernet Circuit Emulation Services (CES) at DS1, DS3, OC3 and OC12 rates.
• An Optical Ethernet Aggregation Switch that concentrates flows onto Gigabit Ethernet interfaces
• An Optical Ethernet Core Switch supporting up to 30 10 Gbps interfaces in a non-blocking configuration (pricing begins at $15,000 list)

Atrica’s platform is currently in beta testing at T-Nova, a subsidiary of T-Systems, Europe's No. 2 systems house (and part of Deutsche Telekom).  http://www.atricanetworks.net/
Atrica, April 23, 2001
