Fujitsu enhances SONET platform

Fujitsu Network Communications last week announced enhancements to its Flashwave 4100 Multi-Service Provisioning Platform designed to improve delivery of data services, including Ethernet-over-SONET.

Fujitsu also announced two OEM deals, including one with edge switch maker and marketing partner Hammerhead Systems.

The enhancements let carriers offer traditional private line, Ethernet augmented with Resilient Packet Ring (RPR ) technology, and storage services in a single SONET platform that scales from OC-3 to OC-48, Fujitsu says.

With this release, SONET, RPR, Generic Framing Procedure (GFP), Virtual Concatenation (VCAT) and Link Capacity Adjustment Scheme capabilities have been converged on the Flashwave 4100. This lets users offer carrier-class 10M bit/sec to Gigabit Ethernet Line and LAN services with detailed bandwidth provisioning, statistical multiplexing, class of service and protection switching, Fujitsu says. New Fibre Channel/Fibre Connection interfaces provide support for storage-area network services for disaster recovery, storage consolidation and remote data mirroring.

New OC-n line and service interfaces include support for Small Form-factor Pluggable (SFP) technology, intended to minimize sparing requirements. To increase fiber capacity, the MSPP has Coarse Wavelength Division Multiplexing interface options designed to enable multiple SONET networks to share a single pair of fibers. A new quad-port OC-3 service unit and enhanced OC-12 line unit offer increased density, Fujitsu says.

The Flashwave 4100 Large Shelf configuration offers OC-3 to OC-48 line interfaces and 12 service interface slots. The Small Shelf offers six service interface slots. Both versions share all plug-in units and SFPs.

It’s Hammerhead time

Features of the edge switch Fujitsu will be reselling:
• Support for pseudowire and Dry Martini techniques to merger Layer 2/Layer 3 operations.
• High-density fan-in of traffic across a range of new and legacy service interfaces, media and speeds.
• Grooming and service-level details across a range of applications and protocols.
• Trunking across an ATM and MPLS backbone and control plane.

For edge switching, Fujitsu will resell Hammerhead's HSX 6000 switch as the Fujitsu Flashwave 6400 Layer 2.5 aggregation switch. Hammerhead's switches are intended to help service providers manage the transition of their legacy - but revenue-rich - data services from an ATM core to an MPLS core, and tap an Ethernet opportunity pegged by analysts to approach $20 billion by 2010.

The switch performs Ethernet aggregation, packet-enabled access and pseudowire termination, and integrates with the SONET/SDH infrastructure using GFP and X.86 techniques. It competes with multiservice edge aggregation features of switches from Lucent and Nortel, and routers from Cisco and Juniper.

Fujitsu says it will also resell BTI Photonics Systems' Netstender platform as the Flashwave 7120 optical extension system. This system transports services over spans that exceed the available fiber capacity or reach of metropolitan optics.

Netstender allows carriers to combine multiplexing, amplification, signal conditioning, optical add/drop and performance monitoring in a system deployed in metropolitan and regional networks.

Flashwave 7120 scales to 23 service slots from multiple shelves, managed as a single network element with a single processor.
