Fujitsu and SwitchCore provide Leading Edge Solutions for Converged Metropolitan Area Networks

Send to friend

Fujitsu Microelectronics Europe (FME) and SwitchCore, two leading suppliers of silicon to the communications industry, today announce that they have joined forces to provide advanced solutions for converged Metro, Access and Core networks.

As a first step in this joint effort, the companies have demonstrated the interworking of FMEs highly integrated Ethernet-over-SDH/SONET device MB87M2181 with SwitchCores industry-leading Ethernet switch CXE-2139. With this unique combination of carrier-class Ethernet switching and highly reliable SDH/SONET-based transport technology, telecom systems providers can deliver content-aware quality of service over traditional backbone infrastructures. Systems using this solution will be able to deliver flexible, robust and cost-effective services to end-customers, especially for emerging applications such as IPTV and Video-on-Demand.

SwitchCores outstanding expertise in carrier-class Ethernet switching technology enables us to provide complete systems solutions for end-to-end applications to our telecom customer base, said Dirk Weinsziehr, FME's Senior Director of Marketing. SwitchCores products complement our SDH/SONET and Ethernet mapping products as well as our own high-end Ethernet Switching devices creating a unique portfolio.

As a leading supplier of components to converging telecom networks it is essential for us to enable, demonstrate and provide solutions for IP and  SDH/SONET as well as OTN networks, said Erwin Leichtle, CEO of SwitchCore. Combining our products with the FME devices into reference designs for next-generation networks, will give our customers the quick time-to-market they need to successfully deploy multi-service equipment.

The first reference design will be a platform offering different service levels by using the SwitchCore CXE-2139 to implement multiple traffic classes. The CXE2139 allows customers to handle the bursty incoming Ethernet traffic in a way that important packets (e.g. voice, video) are sent first and other packets (e.g. e-mail) are queued in cases of congestion (traffic shaping). The resulting Ethernet traffic is then mapped using GFP, Virtual Concatenation and LCAS to efficiently use the available network bandwidth, into a TDM stream using FMEs MB87M2181. Then it frames the stream into SDH/SONET to allow robust and reliable optical long distance transmission. The integrated cross-connect allows fast protection switching between multiple line interfaces based on the standard SDH monitoring and alarm functions to meet carrier requirements.

Step-by-step the co-operation of SwitchCore and FME will integrate the devices of both companies into reference designs for end-to-end systems applications supporting  PDH, 10M to 10G Ethernet, STM-1 to STM-256 SDH and OTU-2 to OTU-3 OTN applications, added Dirk Weinsziehr.
