“…Both sides of the communication, the OBE and the CCE, run MPTCP with the redundant scheduler [12], which was developed by our research team and added to the Linux kernel (v 3.17.0) in 2015. This scheduler provides E2E redundancy by duplicating and sending every packet through all available network interfaces, as represented by continuous red-LTE-and discontinuous green-WiFi-lines in Figure 3.…”

Railway communications are closely impacted by the evolution and availability of new wireless communication technologies. Traditionally, the critical nature of railway services, the long lifecycle of rolling stock, and their certification processes challenge the adoption of the latest communication technologies. A current railway telecom trend to solve this problem is to design a flexible and adaptable communication architecture that enables the detachment of the railway services—at the application layer—and the access technologies underneath, such as 5G and beyond. One of the enablers of this detachment approach is software-defined networking (SDN)—included in 5G architecture—due to its ability to programmatically and dynamically control the network behavior via open interfaces and abstract lower-level functionalities. In this paper, we design a novel railway train-to-ground (T2G) communication architecture based on the 5G technological enabler SDN and on the transport-level redundancy technique multipath TCP (MPTCP). The goal is to provide an adaptable and multitechnology communication service while enhancing the network performance of current systems. MPTCP offers end-to-end (E2E) redundancy by the aggregation of multiple access technologies, and SDN introduces path diversity to offer a resilient and reliable communication. We carry out simulation studies to compare the performance of the legacy communication architecture with our novel approach. The results demonstrate a clear improvement in the failover response time while maintaining and even improving the uplink and downlink overall data rates.

“…Diferentes trabalhos apresentam propostas de escalonadores redundantes. Em [Lopez et al 2015, Lopez et al 2016, os autores propuseram uma estratégia de redundância para o MPTCP em que os pacotes de dados são replicados em múltiplos sub-fluxos. A estratégia focou em aumentar a confiabilidade na transmissão de dados em sistemas SCADA (Supervisory Control and Data Acquisition) contra falhas de transmissão.…”

“…De um modo geral, os benefícios destes escalonadores redundantes são limitados se os caminhos são compartilhados. Para este fim, em [Lopez et al 2016] os autores propuseram uma abordagem em que o protocolo MPLS (Multiprotocol Label Switching) garante a diversidade de caminhos ao MPTCP, tendo como base o escalonador redundante proposto anteriormente em [Lopez et al 2015]. Para garantir a diversidade, o protocolo MPLS encaminha os pacotes provenientes dos sub-fluxos MPTCP por caminhos disjuntos.…”

Esforços acadêmicos e industriais buscam melhorar o desempenho das redes heterogêneas sem fio para que ofereçam os requisitos míninos de latência e vazãoás aplicações sensíveis ao atraso, tais como jogos online, e fluxos de voz e vídeo. O Protocolo de Controle de Transmissão Multi-caminhos (MPTCP) foi projetado para atender a essa demanda. Ele provê um escalonador redundante, que replica os pacotes de dados em múltiplos caminhos, para contrabalançar os efeitos negativos da heterogeneidade. Entretanto, gargalos compartilhados entre os caminhos fim-a-fim reduzem os benefícios providos pelo escalonador. Desta forma, este trabalho apresenta RED (REdundant Diversity scheduling), um escalonador que prioriza a replicação dos pacotes por caminhos não-correlacionados. RED replica os pacotes nos caminhos com base no coeficiente de correlação de Spearman. Os resultados demonstram que RED prioriza o uso de caminhos com baixa correlação e reduz a sobrecarga na rede com um menor número de pacotes replicados, além de prover uma melhora significativa no desempenho da transmissão.

“…In the SECRET project we developed a redundant scheduler for MPTCP, which sends the same information replicated through all the available interfaces with the aim of increasing the resilience of the communication whereas the delay and jitter are reduced because MPTCP/TCP retransmissions are minimized [5]. The code of this new scheduler for MPTCP was made publicly available 2 once the SECRET project finished and then we also collaborated to achieve the inclusion of a redundant scheduler in the official implementation of MPTCP for the Linux kernel 3 .…”

Abstract. This paper presents the setup of a demonstrator based on Multipath TCP protocol to provide a multi bearer-WiFi and WiMAXand resilient agnostic layer to support train-to-ground IP communication. The adaptable communication and resilient architecture consists of three main blocks: an Acquisition System, a Detection System and a Multipath Communication System. Several tests carried out with jamming devices disturbing the data transfer established between the end devices demonstrate the resilient capability and performance of the proposed architecture to overcome electromagnetic attacks.
