Signaling Protocol for Lightpath Provisioning

by Srinivasan Seetharaman, Arjan Durresi, Raj Jain
"... Challenges presented by the exponential growth of the Internet have resulted in the intense demand for broadband services. Providing bandwidth and connectivity on demand has risen to be an important goal of the service providers. To realize this, signaling in the optical network seems to be a critic ..."
Abstract - Add to MetaCart
choices pertaining to lightpath services are outlined. Signaling procedure for ensuring dynamic end-to-end lightpath setup has also been presented. Path provisioning comprises a string of operations like service & neighbor discovery, route computation, signaling requests, and path setup. This paper

Differentiated Quality-of-Protection Provisioning in Optical/MPLS Networks

by Canhui (Sam) Ou, Biswanath Mukherjee , 2004
"... This paper investigates the problem of dynamic survivable lightpath provisioning against single node/link failures in optical mesh networks employing wavelengthdivision multiplexing (WDM). We present a new approach to provisioning lightpath requests according to their differentiated quality-of-pro ..."

Design of Protected Working Capacity Envelopes Based on p-Cycles: An Alternative Framework for Survivable Automated Lightpath Provisioning

by Gangxiang Shen, Wayne D. Grover - PERFORMANCE EVALUATION AND PLANNING METHODS FOR THE NEXT GENERATION INTERNET , 2004
"... A recently proposed concept for dynamic provisioning of survivable lightpath services, called the protected working capacity envelope (PWCE) is considered from a network capacity design and blocking standpoint. The PWCE concept offers several attractive properties for a next-generation Internet bas ..."

CUSTOMER-MANAGED END-TO-END LIGHTPATH PROVISIONING

by Jing Wu, J. Michel Savoie, Scott Campbell, Hanxi Zhang, Gregor V. Bochmann, Bill St. Arnaud
"... Abstract: Customer owned and managed optical networks bring new cost-saving benefits. Two types of such networks are becoming widely used: metro dark fiber networks and long-haul leased wavelength networks. Customers may invoke a special QoS mechanism where end-to-end lightpaths are dynamically esta ..."
