Optical Quality of Service (QoS) for different classes of service in dynamic transparent optical
networks is here addressed through Four Wave Mixing (FWM)-aware algorithms. The traffic …

This paper concerns Quality of Service (QoS) provisioning in Optical Packet Switching (OPS)
networks. We address the topic by proposing Dynamic Wavelength Grouping (DWG) for …

In this paper, quality-of-service (QoS) routing and service-specific functions in optical
networks are proposed. We first present two QoS-routing algorithms, which differ in the way …

This paper considers an optical packet-switched node subject to asynchronous, variable-
length packets and connection-oriented operation. We firstly address the problem of setting …

This paper deals with the problem of service differentiation in an optical packet-switched
backbone. A QoS-aware network function based on different routing and contention …

Crosstalk originating from optical switching devices and demultiplexers can be the dominant
physical impairment in large all-optical networks. When a centralized network controller …

Physical layer impairments may require highly complex implementations of the control plane
in dynamic networks with quality of service (QoS) constraints. In order to alleviate this …

As an optical signal propagates along a lightpath to its destination in wavelength-routed
optical networks (WRONs), the quality of service (QoS) will be degraded by transmission …

The wavelength continuity constraint on the routing and wavelength assignment algorithms
gives rise to a serious problem of fairness due to which longer-hop lightpaths (4-hop, 5-hop) …

In this paper dynamic routing and wavelength assignment strategies have been proposed
for multiclass WDM optical networks. Multiclass optical networks provide multiple classes of …
