Availability Analysis of Shared Protection Schemes for On-line Connection Provisioning
نویسندگان
چکیده
On-line connection provisioning with availability guarantees has to meet the double challenge of assigning resources to connections sparingly and ensuring that connection availability remains above a certain threshold. After having selected an appropriate protection scheme the first aim is achieved primarily by means of sharing backup resources, while the second aim calls for well-conceived restrictions on backup resource sharing rules. The paper investigates the trade-offs that are behind the choice of protection schemes and sharing rule restrictions with respect to blocking probability and connection availability. Results of simulations carried out in a European WDM network topology are used to draw conclusions.

A novel fault management approach for DWDM optical networks
Connection availability is considered as a critical metric when providing differentiated services in WavelengthDivision Multiplexing mesh networks. Indeed, one of the major concerns of optical network operators is related to improving the availability of services provided to their highest-class clients. Achieving this objective is possible through managing faults using the different classical p...
متن کاملService Provisioning to Provide Per-Connection-Based Availability Guarantee in WDM Mesh Networks
Protection schemes for WDM mesh networks (dedicated-path, shared-path, etc.) are typically based on the single-failure scenario. When fiber-cut rate and network maintenance frequency are high, the network operator needs novel methods to handle multiple, near-simultaneous failures where different network components (including fiber spans) may have different failure rates. Service reliability det...

متن کاملTraffic grooming for survivable WDM networks - shared protection
This paper investigates the survivable trafficgrooming problem for optical mesh networks employing wavelength-division multiplexing (WDM). In the dynamic-provisioning context, a typical connection request may require bandwidth less than that of a wavelength channel, and it may also require protection from network failures, typically fiber cuts. Based on a generic grooming-node architecture, we ...
