SRPerf: a Performance Evaluation Framework for IPv6 Segment Routing
Ahmed Abdelsalam, Pier Luigi Ventre, Carmine Scarpitta +5
Segment Routing is a form of loose source routing. It provides the ability to include a list of instructions (called segments), in the packet headers. The Segment Routing architect…
Segment Routing: a Comprehensive Survey of Research Activities, Standardization Efforts and Implementation Results
Pier Luigi Ventre, Stefano Salsano, Marco Polverini +5
Fixed and mobile telecom operators, enterprise network operators and cloud providers strive to face the challenging demands coming from the evolution of IP networks (e.g. huge band…
An Efficient Linux Kernel Implementation of Service Function Chaining for legacy VNFs based on IPv6 Segment Routing
Andrea Mayer, Stefano Salsano, Pier Luigi Ventre +3
We consider the IPv6 Segment Routing (SRv6) technology for Service Function Chaining of Virtual Network Functions (VNFs). Most of the VNFs are legacy VNFs (not aware of the SRv6 te…
SDN Architecture and Southbound APIs for IPv6 Segment Routing Enabled Wide Area Networks
Pier Luigi Ventre, Mohammad Mahdi Tajiki, Stefano Salsano +1
The SRv6 architecture (Segment Routing based on IPv6 data plane) is a promising solution to support services like Traffic Engineering, Service Function Chaining and Virtual Private…
On the Fly Orchestration of Unikernels: Tuning and Performance Evaluation of Virtual Infrastructure Managers
Pier Luigi Ventre, Paolo Lungaroni, Giuseppe Siracusano +4
Network operators are facing significant challenges meeting the demand for more bandwidth, agile infrastructures, innovative services, while keeping costs low. Network Functions Vi…
Deploying SDN in GÉANT production network
Pier Luigi Ventre, Jordi Ortiz, Alaitz Mendiola +7
Since the demand for more bandwidth, agile infrastructures and services grows, it becomes challenging for Service Providers like GÉANT to manage the proprietary underlay, while kee…
D-STREAMON: from middlebox to distributed NFV framework for network monitoring
Pier Luigi Ventre, Alberto Caponi, Giuseppe Siracusano +4
Many reasons make NFV an attractive paradigm for IT security: lowers costs, agile operations and better isolation as well as fast security updates, improved incident responses and…
Revisiting Open eXchange Points with Software Defined Networking
Pier Luigi Ventre, Bojan Jakovljevic, David Schmitz +6
The introduction of SDN in Service Providers' networks like GEANT is a challenging task. Prototypes of new generation services have to exhibit "carrier grade" characteristics, meet…
D-STREAMON - a NFV-capable distributed framework for network monitoring
Pier Luigi Ventre, Alberto Caponi, Davide Palmisano +4
Many reasons make NFV an attractive paradigm for IT security: lowers costs, agile operations and better isolation as well as fast security updates, improved incident responses and…
Accurate and Efficient Measurements of IP level Performance to Drive Interface Selection in Heterogeneous Wireless Networks
Stefano Salsano, Fabio Patriarca, Francesco Lo Presti +2
Optimal interface selection is a key mobility management issue in heterogeneous wireless networks. Measuring the physical or link level performance on a given wireless access netwo…
PMSR - Poor Man's Segment Routing, a minimalistic approach to Segment Routing and a Traffic Engineering use case
Stefano Salsano, Luca Veltri, Luca Davoli +2
The current specification of the Segment Routing (SR) architecture requires enhancements to the intra-domain routing protocols (e.g. OSPF and IS-IS) so that the nodes can advertise…
Traffic Engineering with Segment Routing: SDN-based Architectural Design and Open Source Implementation
Luca Davoli, Luca Veltri, Pier Luigi Ventre +2
Traffic Engineering (TE) in IP carrier networks is one of the functions that can benefit from the Software Defined Networking paradigm. By logically centralizing the control of the…
Hybrid IP/SDN networking: open implementation and experiment management tools
Stefano Salsano, Pier Luigi Ventre, Francesco Lombardo +6
The introduction of SDN in large-scale IP provider networks is still an open issue and different solutions have been suggested so far. In this paper we propose a hybrid approach th…
ICONA: Inter Cluster ONOS Network Application
M. Gerola, M. Santuari, E. Salvadori +5
Several Network Operating Systems (NOS) have been proposed in the last few years for Software Defined Networks; however, a few of them are currently offering the resiliency, scalab…
Generalized Virtual Networking: an enabler for Service Centric Networking and Network Function Virtualization
Stefano Salsano, Nicola Blefari-Melazzi, Francesco Lo Presti +2
In this paper we introduce the Generalized Virtual Networking (GVN) concept. GVN provides a framework to influence the routing of packets based on service level information that is…
Controller selection in a Wireless Mesh SDN under network partitioning and merging scenarios
Stefano Salsano, Giuseppe Siracusano, Andrea Detti +3
In this paper we consider a Wireless Mesh Network (WMN) integrating SDN principles. The Wireless Mesh Routers (WMR) are OpenFlow capable switches that can be controlled by SDN cont…
OSHI - Open Source Hybrid IP/SDN networking (and its emulation on Mininet and on distributed SDN testbeds)
Stefano Salsano, Pier Luigi Ventre, Luca Prete +3
The introduction of SDN in IP backbones requires the coexistence of regular IP forwarding and SDN based forwarding. The former is typically applied to best effort Internet traffic,…
