Journal ArticleDOI
RDNA: Residue-Defined Networking Architecture Enabling Ultra-Reliable Low-Latency Datacenters
Alextian B. Liberato,Magnos Martinello,Roberta Lima Gomes,Arash Farhadi Beldachi,Emilio Hugues Salas,Rodolfo da Silva Villaça,Moisés R. N. Ribeiro,George T. Kanellos,Reza Nejabati,Alexander Gorodnik,Dimitra Simeonidou +10 more
TL;DR: RDNA explores the programmability of residues number system as a fundamental concept to define a minimalist forwarding model for core nodes, which achieves 600 ns switching latency per hop with virtually no jitter at core nodes and sub-millisecond failure recovery time.
Journal ArticleDOI
VirtPhy: Fully Programmable NFV Orchestration Architecture for Edge Data Centers
Cristina K. Dominicini,Gilmar L. Vassoler,Leonardo F. Meneses,Rodolfo da Silva Villaça,Moisés R. N. Ribeiro,Magnos Martinello +5 more
TL;DR: V VirtPhy is proposed, a fully programmable architecture for NFV orchestration in edge data centers, based on server-centric topologies, software-defined networking, software switches, distributed service chaining, and source routing, which can efficiently provision NFV service requests.
Proceedings ArticleDOI
SDCCN: A Novel Software Defined Content-Centric Networking Approach
Sergio Charpinel,Celso A. S. Santos,Alex Borges Vieira,Rodolfo da Silva Villaça,Magnos Martinello +4 more
TL;DR: SDCCN is proposed, a SDN approach to CCN that provides programmable forwarding strategy and caching policies that allows fast prototyping and experimentation in CCN and shows programmability of the cache replacement algorithms and the Strategy Layer.
Journal ArticleDOI
KeySFC: Traffic steering using strict source routing for dynamic and efficient network orchestration
Cristina K. Dominicini,Gilmar L. Vassoler,Rodolfo V. Valentim,Rodolfo da Silva Villaça,Moisés R. N. Ribeiro,Magnos Martinello,Eduardo Zambon +6 more
TL;DR: An OpenStack-based prototype demonstrates that the traffic steering scheme provided by KeySFC has the potential to enable efficient traffic engineering and to provide agile path migration per SFC segment.
Proceedings ArticleDOI
AR2C2: Actively replicated controllers for SDN resilient control plane
Eros S. Spalla,Diego Rossi Mafioletti,Alextian B. Liberato,Gilberto Ewald,Christian Esteve Rothenberg,Lasaro Camargos,Rodolfo da Silva Villaça,Magnos Martinello +7 more
TL;DR: This paper explores OpenFlow roles for the design of resilient SDN control plane and proposes AR2C2 as an actively replicated multi-controller strategy and investigates the practical trade-offs on replication overhead and latency as a step forward towards SDN resiliency.
