چکیده

In slotted WDM metro rings employing spatial re-use the problem of fairness is inherent and quite significant. To allow all nodes around the ring to equally share the available bandwidth a novel mechanism based on access credits and executed in a distributed way is proposed. Its performance is evaluated by simulations to show its effectiveness even under highly asymmetric loading and is compared to the wellknown token-based SAT mechanism. Key-Words: MAC, spatial re-use, fairness, MAN, WDM.

A real-time distributed scheduling algorithm for supporting QoS over WDM networks

Most existing or proposed WDM networks employ circuit switching, typically with one session having exclusive use of one entire wavelength. Consequently they are not suitable for data applications involving bursty traac patterns. The MIT AON Consortium 1 has developed an all-optical LAN/MAN testbed which provides time-slotted WDM service and employs fast-tunable transceivers in each optical term...

MetaRing Fairness Control Schemes in All-Optical WDM Rings

W D M rings are receiving significant attention in the field of all-optical networks because their implementation appears to be feasible with state-of-the-art components. Several MAC protocols were recently proposed in order to resolve contentions among nodes sharing the available wavelengths an W D M rings. These MAC protocols achieve high e&ciency but unsatisfactory fairness, due to the asymm...

Multi-MetaRing fairness control in a WDM folded-bus architecture

The paper deals with fairness issues in a slotted, single-hop, WDM (Wavelength Division Multiplexing) optical architecture, based on a folded bus topology, previously proposed as a broadband access system or as a metro network. The peculiar fairness problem arising in this folded bus based architecture is addressed and an extension of the MetaRing protocol to the WDM scenario, named Multi-MetaR...

An Almost Optimal MAC Protocol for All-Optical WDM Multi-Rings with Tunable Transmitters and Fixed Receivers

This paper considers SRR, an almost optimal collision-free access scheme for all-optical packet networks based on WDM multi-channel ring topologies providing slotted channels for transmissions to disjoint subsets of destination nodes. Only a channel inspection capability and local status information are required at nodes in order to implement the access protocol. Since SRR is not able to enforc...
