Dimensioning of SDH/WDM Multilayer Networks

چکیده
Integration of SDH and WDM network technology in dynamic multilayer networks is considered one promising option for migrating from rather static SDH networks to the automatically switched transport network (ASTN) with a dynamic photonic layer. This paper investigates dimensioning of SDH/WDM multilayer networks. Two different approaches for dimensioning network links and nodes are compared for different SDH/WDM multilayer routing schemes. While the first derives the dimensioning directly from the mean traffic load on the individual network links, the second considers the dynamic nature of the latter traffic load by employing the Erlang-B formula for dimensioning. Finally, the impact of transponder overdimensioning on the performance of SDH/WDM multilayer routing schemes is investigated. *This work was partly funded within the MultiTeraNet project (www.multiteranet.de) by the German Bundesministerium für Bildung und Forschung under contract No. 01BP289. 4.

Improving Performance of SDH/SONET-WDM Multilayer Networks Using Weighted Integrated Routing
This work deals with routing schemes in SDH/SONET-WDM multilayer networks applying Synchronous Digital Hierarchy (SDH) or Synchronous Optical Network (SONET) on top of a dynamic photonic network in Wavelength Division Multiplex technology (WDM). The focus are integrated routing schemes which benefit from an integrated view of the SDH/SONET layer and the optical layer. Besides the comparison of ...
متن کاملA New Efficient Integrated Routing Scheme for SDH/SONET-WDM Multilayer Networks
This paper presents and evaluates the new Weighted Integrated Routing scheme to solve the problem of dynamic routing and traffic grooming in meshed SDH/SONET-WDM multilayer networks. Its performance is compared to non-integrated schemes using a cost model.
متن کاملEstimating CapEx in Optical Multilayer Networks
A model for calculating the costs and quantities of required components of a multilayer transport network comprising IP/MPLS-over-SDH/OTN-over-WDM layers is presented. From that a method to estimate the capital expenditures is presented. The method is based on analytical approximations and does not depend on the network topology. Results are presented showing good agreement between the estimati...
متن کاملDimensioning of Mp/wdm Networks with Failure Restoration
This paper proposes new dimensioning methods in an MP/WDM (multi-protocols over WDM) network with static wavelength paths. The network has the following aspects; (1) limited to the near future, the network uses costly OXCs (optical cross-connects) only to replace active paths into the spare paths when a fault occurs, and, (2) every active path does not produce a pair with a spare path since res...
متن کاملDynamic bandwidth adaptation in NG SDH/WDM transport networks using LCAS
Traffic patterns of data services are known to be highly dynamic and have been characterized as self-similar caused by long-range dependent transfer times and file size distributions [8]. This burstiness appears on various time scales and makes link and network dimensioning more difficult compared to classical voice traffic. In this paper, we adopt dynamic bandwidth adaptation to transport netw...
