Marconi has unveiled its Internet Protocol/Multi-Protocol Label Switching strategy, which offers IP/MPLS functionality on a complete family of switch-router platforms scaling from 2.5-480Gbit/s.
The strategy is two pronged. First, it addresses core infrastructures with highly scalable solutions for both new and evolving IP deployments and for evolving current multiservice networks. Second, it addresses the network edge by adding new revenue-generating IP/MPLS services, such as IVirtual Private Networks and MPLS transparent LAN services (TLS).
"Our strategy addresses both legacy and next-generation IP networks," said Nancee Ruzicka, Yankee Group program manager. "Also, Marconi offers both legacy multiservice and next-generation IP infrastructure from a single platform."
With Marconi's strategy, service providers can adjust the switch-routers in their network to accommodate their timeframe for evolution to a multiservice IP network.
Marconi's BXR-48000 multiservice core switch-router supports multiservice functions, such as IP routing and MPLS switching (Label Edge- and Label Switch-Router). The BXR-48000 is a true core router with packet-only interfaces, a distributed forwarding table, central route processing and payload agnostic fabric, suited to multiservice IP cores.
The BXR-48000 also supports IP services with service level agreements; with the PWE3 working group's definition for transport of legacy services; and with carrier-class reliability through one-to-one hardware redundancy and non-service impacting software.
The strategy builds on Marconi's participation in some major MPLS interoperability tests over the past 18 months. "We are one of the first-to-market with standards-based IP/MPLS functionality on a range of 2.5, 10 and 40 Gbit/s legacy multiservice switch routers," said Tom Murray, VP product marketing for Marconi's Broadband Routing & Switching group. "Now, we are offering it on our new 480 Gbit/s BXR-48000 switch router."
- Marconi and Telecom Italia have announced the implementation of DWDM transmission on dispersion-shifted fibre (DSF) quadrupling the number of wavelengths.
Its introduction on Telecom Italia's backbone link between Florence and Rome enables other network operators to implement improved traffic transmission techniques over existing DSF fibre.
"Network providers can look again at their legacy fibre and reconsider its inherent value," said Lorenzo Costagli, VP SDH Development, Marconi "Operators can now deploy advanced DWDM photonics technology over fibre installed for up to 15 years, previously considered unsuitable for high-capacity transmission."
- Marconi has been awarded a new GBP10m contract by British Telecom Wholesale to carry out an upgrade of its intelligent network platform. When complete, the programme will increase platform functionality by demonstrating a new open interface called Parlay.
