“…This process was done exclusively in the data plane (OpenFlow switches) and took less than ten milliseconds, which is an acceptable value for disruption in an inter-domain environment (less than 50 ms [34]). The measured millisecond interval was coherent with the FF mechanism recovery times found in the literature [35,36].…”

“…Hence, for future works, it is interesting to investigate the different approaches for the manipulation of flows in an OpenFlow network, for example, proactive and active strategies [29]. Another idea in this line of thought is to manage and apply a more aware congestion control for the flows, e.g., a switchover mechanism [36] that changes congested flows to different paths during the lifetime of the flows.…”

Abstract:The Border Gateway Protocol (BGP) is the current state-of-the-art inter-domain routing between Autonomous Systems (ASes). Although BGP has different mechanisms to manage outbound traffic in an AS domain, it lacks an efficient tool for inbound traffic control from transit ASes such as Internet Service Providers (ISPs). For inter-domain routing, the BGP's destination-based forwarding paradigm limits the granularity of distributing the network traffic among the multiple paths of the current Internet topology. Thus, this work offered a new architecture to manage incoming traffic in the inter-domain using OpenFlow networks. The architecture explored direct inter-domain communication to exchange control information and the functionalities of the OpenFlow protocol. Based on the achieved results of the size of exchanging messages, the proposed architecture is not only scalable, but also capable of performing load balancing for inbound traffic using different strategies.

“…We have implemented the simulation environment using Mininet 2.2.1 installed on a patched Linux Kernel (4.11.0-rc8+) that supports CAN-Utils Package namespaces [14]. Additionally, we have built the protocol adapters based on TCP/IP Sockets (that ensure retransmission in the case of a packet loss) and CAN-Sockets [23].…”

Autonomous vehicles bring the promise of enhancing the consumer's experience in terms of comfort and convenience and, in particular, the safety of the autonomous vehicle. Safety functions in autonomous vehicles such as Automatic Emergency Braking and Lane Centering Assist rely on computation, information sharing, and the timely actuation of the safety functions. One opportunity to achieve robust autonomous vehicle safety is by enhancing the robustness of in-vehicle networking architectures that support built-in resiliency mechanisms. Software Defined Networking (SDN) is an advanced networking paradigm that allows fine-grained manipulation of routing tables and routing engines and the implementation of complex features such as failover, which is a mechanism of protecting in-vehicle networks from failure, and in which a standby link automatically takes over once the main link fails. In this paper, we leverage SDN network programmability features to enable resiliency in the autonomous vehicle realm. We demonstrate that a Software Defined In-Vehicle Networking (SDIVN) does not add overhead compared to Legacy In-Vehicle Networks (LIVNs) under non-failure conditions and we highlight its superiority in the case of a link failure and its timely delivery of messages. We verify the proposed architectures benefits using a simulation environment that we have developed and we validate our design choices through testing and simulations.

“…Several attempts have been made to achieve faster recovery using the FF group to eliminate the involvement of controller for detouring [8,10,11]. Sharma et al and Katz and Ward [8,24] used Bidirectional Forwarding Detection (BFD) protocol to detect path failure and reroute the flows on the preconfigured alternate path in around 42-48 ms.…”

“…Pre-provisioned recovery schemes, based on end-to-end path protection strategies for handling network failures, are well known and deployed in production networks for faster recovery. Several authors have proposed the SDN-based recovery schemes for single-link failure-handling and showed improved results regarding reduced recovery time [8][9][10][11][12][13]. However, it requires additional signalling mechanism by the failure-affected switches to notify the failure event to the source switch of the primary path, which could cause additional recovery delay.…”

One of the key technical challenges in 5G is to ensure a high level of end-to-end service availability and reliability. Software-defined networking leveraging on a centralized network-forwarding control and management paradigm is expected to fulfil such requirements and even enhance their capabilities, compared to the traditional reliability mechanisms in the legacy network. This paper presents an enhanced forwarding table design for scalable and efficient failover support on multilink failures in OpenFlow networks. The proposed forwarding table is designed with flow grouping and flow aggregation methods to achieve faster link failover and compress the flow rules for alternate paths against multi-link failures. To validate the proposed forwarding table design, we evaluate the performance in the following points: (1) how much resilience can be provided, (2) how many forwarding rules can be reduced to configure the alternate paths against multi-link failures and (3) how rapidly the failover can be achieved. Emulation results confirm that the proposed design reduces the number of disrupted flows and required forwarding rules to configure the alternate paths. We could also identify that it can achieve the recovery in 2-3 ms.
