5G: Virtualization and Security

Abstract: Network virtualization and network security are the most relevant aspects of the 5G cellular systems.
The first aspect refers to the full virtualization of network functions in every section of the network: access, transport and core. Cloud computing is executed both in the core network and at the network edges: Core Cloud Computing and Edge Cloud Computing. Such feature allows, on one side, the Network Slicing techniques to optimize network performance of various vertical market applications. On the other side, Edge Computing is used to optimize network performance, in terms of improved throughput and quality of experience, as well as reduced latencies, and massive data storage. Such Distributed Cloud Computing is orchestrated throughout the edge data centers, the metro and the core data centers, and it is realized according to the paradigm of Cloud-Native Computing.
The second aspect is crucial to the successful deployment of 5G systems, in view of the mission critical applications of the Internet of Things: autonomous driving vehicles, drones, industrial robots, tele-surgery applications, etc. Such 5G applications can create risks to human life. Hence, network security is of supreme importance when deploying such mission critical IoT applications. Communications security services in 5G systems evolve from the classical attributes of confidentiality, integrity and availability, to include two new attributes: “visibility” and “centralized security policy”: both exploit the orchestration of cloud computing resources. Security visibility refers to the disposal of a centralized dashboard for the pervasive monitoring of network status and attacks.  The centralized policy allows a kind of Security-as-a-Service to provide “on demand” various network security functions, such as, intrusion detection & prevention probes, DPI, firewalls, etc.

Alberto Lometti, System & Architecture Senior Director, SM-Optics (SIAE Micro-Electronics Group), Italy

OTN rise, status and perspectives

Abstract: Since the first OTN standards were stabilized in 2001, technology has continued to evolve. Additional new service requirements have materialized, moving from the initial SDH centric paradigm to a more Internet-oriented Ethernet focus, to the current ongoing activities addressing all the emerging aspects of the networks of the future.
This tutorial examines how evolving OTN standards have so far provided telecom networks with a multi-service capable carrier-grade backbone infrastructure supporting lambda and sub-lambda services with guaranteed quality, and how today they are increasing the scope of the technology by addressing metro and aggregation as well as new telecom evolution trends like 5G, IoT, DC Interconnections and multi-tera optical transmission.

Biography

Alberto Lometti was born in Milan in 1959, and received the Dr. Ing. degree (cum Laude) in electronic engineering from the University of Pavia, Italy, in 1984. Since joining the Radio Links Division of Telettra S.p.a. in October of the same year he has spent his entire professional life in R&D moving from analog and digital electronic design, to ASIC design, to system and network design. Since 1991 to 1996 he led the team of ASIC designers who pioneered the introduction of SDH technology in Telettra and later on in Alcatel, after the acquisition. In 1996 he moved to system design extending progressively his responsibility across Alcatel European design centers and dealing with Optical Multi-Service nodes, Cross-Connects and WDM systems. Within Alcatel and then Alcatel-Lucent Optics Division he led the standard activity which contributed to the definition of the new Packet Transport paradigm in optical networks, made concrete by ITU and IETF MPLS-TP standard. Since November 2014 he is in SM-Optics, a company of SIAE Micro-Electronics Group, as System & Architecture Senior Director. In this role he has led the architecture definition activity of SMO new metro-WDM product line (LM1 system family).
He owns 17 patents related to optical transport topics and has authored or co-authored more than 25 papers, most of them presented in international conferences. In 2006 he has been appointed Bell Labs Fellow, the first one in Italy after the merge of Alcatel with Lucent Technologies.

Network Defragmentation

Abstract: It is becoming increasingly important for core networks to be more flexible in order to accommodate the significant growth of cloud and smartphone-enabled applications. In such optical networks, utilization of the optical bandwidth may be fragmented depending on the increase or decrease in the number of optical path routes during operation. In this tutorial, we will discuss network defragmentation in order to achieve more effective use of the bandwidth resource by restructuring and consolidating the fragmented bandwidth, both at the optical layer and at the logical layer.
We will review the different mechanisms for dynamic and adaptive defragmentation. They include the answered to the following questions (i) How to reconfigure, i.e., optimize the combination of (re)provisioning algorithms for defragmentation, (ii) How to migrate traffic: Design connection migration method for defragmentation and try to minimize traffic disruptions. (iii) When to reconfigure: Determine the best timing of each defragmentation operation, (iv) What to reconfigure: Decide how many and which connections to be reconfigured in each defragmentation operation.And last, but not least, we will also discuss how to combine protection and effective defragmentation.

Disaster Recovery in Optical Networks

Abstract: Natural disasters such as earthquakes and floods and man-made disasters such as terrorist attacks can  damage or even destroy large parts of  many types of infrastructure that we all rely on in modern society. Communications is a fundamental infrastructure that must be designed to be resilient to disasters.
