A causa della crescita esponenziale del traffico e della rapida espansione delle infrastrutture di comunicazione in tutto il mondo, il consumo di energia di Internet sta rapidamente diventando un problema. Un approccio naturale per migliorare l'efficienza energetica in Internet è quello di spegnere i dispositivi di rete non necessari (router e link), in modo da ridurre i consumi durante i periodi di basso carico, garantendo al contempo che le domande di traffico siano instradate nella restante sottorete. Verrà introdotta MP-EAN, Management Platform for Energy Aware Networks, una nuova piattaforma per la gestione degli apparati di rete, scritta in Java e basata sull'utilizzo del Simple Network Management Protocol (SNMP). MP-EAN offre un'astrazione di alto livello delle operazioni di gestione di una rete, fornendo un modo semplice, per i ricercatori, di implementare nuove soluzioni per la gestione delle reti di telecomunicazioni. Un modulo software chiamato OCM (OSPF Configurations Manager) è implementato grazie ad MP-EAN. Lo scopo di OCM è quello di adattare dinamicamente la topologia della rete, in termini di link e router attivi, ai diversi scenari di carico, in reti gestite attraverso il protocollo di routing Open Shortest Path First (OSPF). Verrà mostrato come eseguendo MP-EAN e OCM su una rete OSPF consente di adattare dinamicamente la topologia di routing all'attuale livello di carico, rendendo possibile lo spegnimento di quei dispositivi di rete non necessari, e garantendo allo stesso tempo che i livelli di congestione in rete siano sufficientemente bassi per garantire QoS.

Abstract
Due to the exponential traffic growth and the rapid expansion of communication infrastructures worldwide, Internet energy consumption is rapidly becoming an issue. A natural approach to improve the Internet energy efficiency is to switch off the unnecessary network devices (routers and links) to reduce the network consumption during low workload periods, while guaranteeing that traffic demands can still be routed in the remaining subnetwork. MP-EAN, Management Platform for Energy Aware Network, is introduced. MP-EAN is a new network management platform, written in Java, that can be used to easily perform management operations in network devices. Using Simple Network Management Protocol (SNMP) to communicate with the devices, MP-EAN offers a high-level abstraction of the management operations of a network, providing an easy way for researchers to implement new network management solutions. A module called OCM (OSPF Configurations Manager) is implemented on top of MP-EAN. The aim of OCM is to dynamically adapt the network topology, in terms of active routers and links, to different workload scenarios in networks operated with the Open Shortest Path First (OSPF) routing protocol. It will be shown how running MP-EAN and OCM on a network operated with OSPF make it possible to dynamically adapt the routing topology to different workload scenarios, making possible to switch off unnecessary network devices, while guaranteeing that network congestion is low enough to ensure service quality.| File | Dimensione | Formato | |
