Siemens ICN: Reduced Planning Costs in Wavelength Routed Optical Networks
Source/Type: Press Releases - As issued by company

March 25, 2003... Munich, Germany
At OFC in Atlanta, Georgia USA, Siemens ICN will present heuristic formulas derived from simulations to estimate the wavelength demand in photonic networks. Simple and general formulas help carriers and technical sales to reduce network planning costs.

Today's situation in the telecom market is simultaneously characterized by enormous technical progress and a dramatic economic downturn. The economic downturn requires the introduction of new networking technologies even in the transport layer of the backbone networks. In order to save on capital expenditures (CapEx) for next generation transport networks, transparent networking with sparse wavelength conversion and optical light path regeneration must be introduced. It is well accepted that the transparent networking approach will keep the CapEx down to acceptable levels. On the other hand, much discussion on the resulting additional operational costs (OpEx) of the carriers exists. The latter results possibly in an expected increase in the planning effort of the carriers.

To cover this planning problem, simple to use planning methods have to be available for the next generation wavelength routed optical networks (WRONs). Besides these planning methods, technical sales of the system vendors as well as the network planning groups of the network operators need simple algorithms for fast estimation of the costs for a planned network topology with a given traffic demand. Siemens ICN developed equations which allow for a simple estimate of the wavelength demand. From these results networks planners can obtain an estimate of the costs of the photonic layer of a wavelength routed transport network.

OFC 2003: The presentation will be held on March 27th at 9:30 am.

Siemens Information and Communication Networks (IC Networks) is a leading provider of network technology for enterprises, carriers and service providers. Its comprehensive portfolio comprises IP-based convergence solutions for voice and data (HiPath for enterprises, SURPASS for carriers), a full range of solutions for broadband access, and optical transport networks (TransXpress). The Siemens Group thus provides complete solutions from a single source for the infrastructure of the Next Generation Network optimized for a prompt return on investment and to open up new business opportunities for customers. In fiscal 2002 (year-end 30 September) IC Networks posted sales of EUR 9.6 billion.
