A detailed survey of approaches reducing energy consumption of core networks is
presented in this paper. We consider a multilayer architecture, in which the optical layer can …

In this paper, we present a dynamic energy efficient routing and spectrum assignment
algorithm with regenerator placement (RP) capability for elastic optical networks. In this …

In this work, we study the availability-aware survivable virtual network embedding (A-SVNE)
problem in optical interdatacenter networks that use wavelength-division multiplexing. With …

Flexible-grid elastic optical networks (EONs) have attracted intensive research interests for
the agile spectrum management in the optical layer. Meanwhile, due to the relatively small …

It is known that in multilayer interdatacenter optical networks (ML-IDCONs), network services
can generate numerous data-oriented tasks (DoTs) that require not only inter-datacenter …

In order to tackle the increasing heterogeneous global Internet traffic, mixed-line-rate (MLR)
optical wavelength division multiplexed (WDM) networks have emerged as the cost-and …

This paper investigates hybrid immediate reservation (IR) and advance reservation (AR)
service provisioning in elastic optical networks, with the objective to minimize IR/AR service …

Nowadays, the booming of emerging network services have shifted the major traffic pattern
in metro-aggregation networks from point-to-point (P2P) to hub-and-spoke (H&S). Hence, it …

It is known that with the multi-domain scenario, elastic optical networks (EONs) can improve
network scalability, extend service coverage, and handle the multi-carrier situation …

Multidomain elastic optical networks (MD-EONs) help to improve network scalability, extend
service coverage, and facilitate good interoperability to orchestrate administrative domains …
