“…On the other hand, by service layer cost we consider metrics such as processing resources of energy availability, which are metrics that must be considered in scenarios with heterogeneous NEs such as the IoT [9,10]. [12,9], where authors consider optical infrastructures as a key building block of IoT. However, these studies do not take into account novel network architectures such as the PCE or ILSA schemes.…”

The recently coined Internet of Things (IoT) paradigm leverages a large volume of heterogeneous network elements (NEs) demanding broad connectivity anywhere, anytime and anyhow, fueling the deployment of innovative Internet services, such as Cloud or Fog Computing, Data Center Networks (DCNs), Smart Cities or Smart Transportation. The proper deployment of these novel Internet services is imposing hard connectivity constraints, such as high transmission capacity, reliable communications, as well as an efficient control scheme capable of enabling an agile coordination of actions in large heterogeneous scenarios. In recent years, novel control schemes, such as the so-called Path Computation Element (PCE) has gained momentum in the network research community turning into real PCE implementations. Indeed, there is a wealth of studies assessing the PCE performance, clearly showing the potential benefits of decoupling routing control tasks from the forwarding nodes. Nevertheless, recognized the need for a control solution in IoT scenarios, there is no much published information analyzing PCE benefits in these IoT scenarios. In this paper, we provide an insight particularly demonstrating how the PCE may gracefully provide support to the service composition in an agile manner, handling the specific constraints and requirements found in IoT scenarios. To this end, we propose a novel PCE strategy referred to as Service-Oriented PCE (SPCE), which enables network-aware service composition.

Abstract-IP/MPLS and Optical technologies are the foundations of current Carrier-Grade Networks (CGNs), due to both the flexibility of IP/MPLS to provide services with distinct requirements and the high transport capacity offered by new Optical technologies, such as Elastic Optical Networks (EONs). However, despite of the widespread adoption of these two technologies, interoperability issues still impact on key network features, in particular on resilience capabilities. Resilience is gaining momentum in recent years due to the advent of new CGN scenarios, such as Data Center Networks (DCNs), where a link or a node failure might lead to a substantial traffic loss. We consider that any potential contribution on the resilience arena, must be built on top of a solid knowledge of available proposals emphasizing most appealing research trends and the limitations affecting the management of resilience in CGNs. Aligned to this scenario, the main goals of this article are: (1) compile distinct approaches for managing resilience; (2) describe in a comprehensive manner, the challenges faced by CGN operators in order to manage resilience; (3) show why current solutions for managing resilience do not completely address the interoperability issues present in multilayer CGNs with multi-vendor settings, and; (4) provide insights for future trends.

“…In fact, clouds need proper consideration for network dynamics, such as capacity, quality of service (QoS), reservation, and complete integration and federation of the clouds. In such an environment, the transport infrastructure could be virtualized and treated as a type and part of the service [5,6]. The optical network infrastructure that follows a traditional architectural approach to creating and delivering network services may not be able to be part of the cloud's architecture and thus meet its requirements in a seamless way.…”

Abstract-This paper presents a novel service-oriented network architecture to bridge the informational gap between user applications and optical networks providing technology-agnostic multigranular optical network services for clouds. A mediation layer (service plane) between user applications and network control is proposed to facilitate a mapping process between user application requests and the network services. At the network level, a multigranular optical network (MGON) is proposed and implemented to support dynamic wavelength and subwavelength granularities with different transport formats [optical burst switched (OBS), optical burst transport (OBT)], reservation protocols (one-way, two-way), and different quality-of-service (QoS) levels per service type. The service-oriented multigranular optical network has been designed, implemented, and demonstrated on an experimental testbed. The testbed consists of service and network resource provisioning, service abstraction, and network resource virtualization. The serviceto-network interoperation is provided by means of a gateway that maps service requests to technology-specific parameters and a common signaling channel for both service and network resource provisioning.
