| Summary: | The network robustness and reliability are strongly influenced by the implementation of redundancy and its ability of
reacting to changes. In situations where packet loss or maximum latency requirements are critical, replication of resources
and information may become the optimal technique. To this end, the IEC 62439-3 Parallel Redundancy Protocol (PRP)
provides seamless recovery in layer 2 networks by delegating the redundancy management to the end-nodes. In this
paper, we present a combination of the Software-Defined Networking (SDN) approach and PRP topologies to establish
a higher level of redundancy and thereby, through several active paths provisioned via the OpenFlow protocol, the
global reliability is increased, as well as data flows are managed efficiently. Hence, the experiments with multiple
failure scenarios, which have been run over the Mininet network emulator, show the improvement in the availability and
responsiveness over other traditional technologies based on a single active path. |
