In general, humans follow a routine with highly predictable daily movements. For instance, we commute from home to work on basis and visit selected set of places for commercial recreational purposes during the nights weekends. The use mobile phones increases when commuting via public transportation, lunch breaks, at night. Such regular behavior creates spatiotemporal fluctuations traffic patterns. this paper, introduce matheuristic dynamic optical routing, which can be implemented as an...

In recent years, researchers realized that the analysis of traffic datasets can reveal valuable information for management mobile and metro-core networks. That is getting more true with increase in use social media Internet applications on devices. this work, we focus deep learning methods to make prediction matrices allow us proactively optimize resource allocations optical backbone Recurrent Neural Networks (RNNs) are designed sequence problems they achieved great results past years tasks...

Recently, machine learning (ML) has attracted the attention of both researchers and practitioners to address several issues in optical networking field. This trend been mainly driven by huge amount available data (i.e., signal quality indicators, network alarms, etc.) large number optimization parameters which feature current networks (such as, modulation format, lightpath routes, transport wavelength, etc.). In this paper, we leverage techniques from ML discipline efficiently accomplish...

Due to the highly predictable daily movements of citizens in urban areas, mobile traffic shows repetitive patterns with spatio-temporal variations. This phenomenon is known as Tidal Effect analogy rise and fall sea levels. Recognizing defining load at base station thus plays a vital role engineering, network design balancing since it represents an important solution for Internet Service Providers (ISPs) that face congestion problems or over-provisioning link capacity. Previous works have...

The growth of intra data center communications, cloud computing and multimedia content applications force transport network providers to allocate resources faster, smarter dynamically. Software-defined Networking (SDN), has been proposed create a unified control plane for networks (Transport SDN). This article presents an overview on Transport SDN proposals based OpenFlow, the de facto protocol. OpenFlow is at forefront models several testbeds have proved implementation multi-domain...

Multipath TCP is an extension to protocol that allows a single connection be split across multiple paths. MPTCP overcomes few limitations of thereby offering added benefits like increased throughput and network resource utilization resilience possible link failures. Different data paths over the face different end-to-end path delay. The performance affected not only by delay but also difference in delays experienced various same connection. runs on host, it aware underlying topology. Hosts...

In general, humans follow highly predictable daily movements. We commute from residential to working and/or educational areas in a basis, and we have selection of commercial recreational for the nights weekends. also use mobile phone at regular hours, example when commuting, during lunch break night. Such behavior creates spatio-temporal fluctuations traffic patterns, which analogy periodical rise fall sea levels, its known as tidal phenomenon. this paper, propose suite on-line matheuristics...

This article reviews use of NFC in Application areas, cases, potential benefits and barriers, will be presented. The present study provides guidance for researchers adopting deploying medical main security applications are patient's identification medication control. can also used resource control, management data acquisition remote delivery applications. are: improvement care quality,...

This work demonstrates a hierarchical control plane architecture for Software Defined Networking (SDN)-based Segment Routing (SR) in multi-domain networks. An orchestrator application, on top of multiple open source SDN controllers, creates using northbound RESTFul APIs controllers. The has control, visibility and traffic engineering capabilities to manage SR service creation. Standard southbound interfaces with proper extensions are exploited tunnels the MPLS data plane.

We propose a methodology to optimize the decisions of mobile metro-core network orchestration systems. use machine-learning-based traffic prediction dynamically provision resources in advance. Resource allocation and reconfigurations are calculated through heuristic that combines reinforcement learning mixed integer linear programming.

The fifth generation telecommunication standard (5G) will make use of novel technologies, such as Software Defined Networks (SDN) and Network Function Virtualization (NFV). New models are integrating SDN NFV in a control plane entity responsible the Management Orchestration (MANO) whole system. This entity, acting director 5G plane, is known Service Orchestrator. work presents SENATUS, an experimental service orchestrator targeting research testing environments. SENATUS implements set...

Enterprise Networking (EN) services are source of high revenues for carriers. However, the traditional way providing and selling those to enterprise business customers is ossified unsatisfactory users. High prices, static connections slow time provision, make users doubtful about whether guaranteed connectivity worth price push them look alternative solutions. That poses carriers at risk customer leak. This paper explains how SDN can foster evolution EN in order appealing again enterprises....

Nowadays, companies strongly rely on Virtual Private Networks (VPNs) to deliver services between geographically distributed branch offices. Internet Service Providers (ISPs) must therefore offer a reliable and cost-effective connectivity solution. VPNs are commonly based static bandwidth allocation over MPLS tunnels, which cause over-provisioning under-utilization of network resources. Software Defined Networking (SDN) appears as solution provide agile enterprise networking while reducing...
