Quality of service on the arrowhead framework

Abstract

Quality of Service (QoS) is an important enablerfor communication in industrial environments. The ArrowheadFramework was created to support local cloud functionalitiesfor automation applications by means of a Service OrientedArchitecture. To this aim, the framework offers a number ofservices that ease application development, among them theQoSSetup and the Monitor services, the first used to verify andconfigure QoS in the local cloud, and the second for onlinemonitoring of QoS. This paper describes how the QoSSetupand Monitor services are provided in a Arrowhead-compliantSystem of Systems, detailing both the principles and algorithmsemployed, and how the services are implemented. Experimentalresults are provided, from a demonstrator built over a real-timeEthernet network. (QoS) is an important enabler for communication in industrial environments.

“…Arrowhead local cloud autonomous configurations is the most common use-case developed nowadays [49][50][51][52]54,55]. The studied use-cases refer to service interaction through gateways for inter-cloud collaboration within the Arrowhead Framework [39], secure and trusted inter-cloud communications in the Arrowhead Framework [48], interacting with the Arrowhead local cloud:…”

“…The results outlined that the development pace and efficiency of the enterprise have been improved by 50-75% when using the Arrowhead Framework and changing development processes/practices. Not only criteria related to efficiency and security must be taken into consideration when using Arrowhead Framework architecture, but QoS should be a key performance parameter [53][54][55]. In [53], the performances of a Long-Term Evolution (LTE) network (with a maximum capacity of the radio cell of 60/30 mbps) in different scenarios of IIoT intra-cloud use cases are evaluated considering the model for the edge level Arrowhead Local Cloud in Arrowhead Framework and Arrowhead Core devices (provider and consumer).…”

“…This delay is unacceptable in an LTE communication because it leads to QoS degradation in IIoT use cases. Arrowhead local cloud autonomous configurations is the most common use-case developed nowadays [49][50][51][52]54,55]. The studied use-cases refer to service interaction through gateways for intercloud collaboration within the Arrowhead Framework [39], secure and trusted inter-cloud communications in the Arrowhead Framework [48], interacting with the Arrowhead local cloud: Onboarding procedure [50] and a multi-usable cloud service platform: A case study on improved development pace and efficiency [51].…”

“…According to [54], QoSSetup and Monitor are core services for QoS supporting in Arrowhead local clouds ( Figure 13). Testbed based on Flexible Time-Triggered Switched Ethernet (FTT-SE) protocol measures the time interval the consumer requires until it starts using a QoS-enabled orchestrated service, and the effect of QoS guarantees, considering that the service producer is limited to only one service.…”
