RT info:eu-repo/semantics/article T1 ARP-P4: deep analysis of a hybrid SDN ARP-Path/P4-Runtime switch A1 Martinez Yelmo, Isaias A1 Álvarez Horcajo, Joaquín A1 Briso-Montiano Marco, Miguel A1 López Pajares, Diego A1 Rojas Sánchez, Elisa K1 P4 K1 P4-Runtime K1 SDN K1 Hybrid SDN K1 Telecomunicaciones K1 Telecommunication AB The Software-Defined Networking (SDN) architecture decouples the control plane from the data plane, but it does not explicitly state where the control should be located. This article analyses the benefits of maintaining the control as close as possible to the data plane, instead of the more traditional centralised control plane approach. To this purpose, it delves into the study of ARP-P4, a hybrid software switch defined by using the P4 language to facilitate its future use and deployment in P4 targets. Its hybrid properties come from supporting two complementary different ways of establishing paths: a centralised SDN approach based on P4-Runtime and a traditional distributed approach based on the ARP-Path protocol that obtains a similar performance to centralised solutions based on Equal Cost Multi-Path (ECMP) and Dijkstra. The results show the feasibility of hybrid devices that combine different forwarding paradigms without losing performance with respect to well-known solutions such as ECMP, and how their combined use can lead to enhance and scale communication networks.
