The main reference of the research carried out in SCNL is the Quality of Service (QoS) management in heterogeneous networks wired, satellite and wireless portions. The scientific-technological objective is to eliminate the differences among the heterogeneous portions of the network through the definition and the use of appropriate interfaces and algorithms that make transparent interconnection of various components of the network and offer specific quality assurance to the users.
Classical networks, such as the Internet, are based on assumptions of “universal connectivity” and “global information”. However, there are different kind of networks in which these assumptions do not hold, e.g. sensor networks, pocket switched networks, vehicular ad-hoc networks and interplanetary networks. A common denomination of these networks is Intermittently Connected Networks. As in such contexts the networks may be disconnected most of the time or it may even happen that there is never an end-to-end path available between source and a destination, classical routing and congestion control algorithms fail. Delay Tolerant Networking paradigm has been proposed to cope with the challenges and issues of ICNs. Inside this framework, different research topics are studied:

Software Defined Networking (SDN) is revolutionizing both the networking industry by enabling programmability, easier management and faster innovation, and the research community allowing the study and the independent evolution of the control and data planes, not more sticked with the concept of the distributed control plane. One important aspect of SDN paradigm is related to the scalability issues: decoupling data and control planes brings about scalability concerns, and moving traditionally local control functionalities to a remote controller can potentially result in new bottlenecks.

Nowadays a lot of important applications such as public services, Internet banking, and also systems devoted to defense are dependent on networks and computers. For this reason they are often the target of malicious software (malware, spyware, etc...) attacks. Malware is software specifically designed to insert itself in a computer system without the approval of the owner using techniques such as trojans, backdoors, keylogger, and worms. To prevent these type of attack it is necessary to accurately detect malware and other type of intrusions.
