Quality of Service-enabled applications and services rely on Traffic Engineering-based (TE)
Label Switched Paths (LSP) established in core networks and controlled by the GMPLS …

In the last twenty years, optical networks have witnessed recurrent changes in their
management and control architecture. In this paper, we present a historical timeline and a …

Network function virtualization (NFV) in elastic optical datacenter interconnections (EO-
DCIs) enables flexible and timely deployment of network services. However, as the service …

Segment routing is an emerging traffic engineering technique relying on Multi-protocol Label-
Switched (MPLS) label stacking to steer traffic using the source-routing paradigm. Traffic …

In this paper, a new fast and accurate methodology to evaluate the blocking probability
(burst loss probability) in dynamic WDM networks without wavelength conversion is …

Crankback re-routing extensions can offer significant improvements in the successful setup
of Label Switched Paths (LSPs) by allowing new retries on alternate paths that circumvent …

In wavelength-routed networks based on a GMPLS control plane, the resource reservation
protocol with traffic engineering extensions (RSVP-TE) allows to establish end-to-end …

In WDM backbone networks, the traffic pattern evolves constantly due to the nature of the
demand itself or because of equipment failures leading to reroute affected connections. In …

A Service Level Agreement (SLA) is a contract between a Service Provider (SP) and a
customer that typically includes the customer requirements that the SP guarantees, the fee …

Sub-band virtual concatenation (VCAT) technique can help improve spectrum utilization of
an elastic optical network (EON). On the other hand, availability is an important service level …
