Standard Ethernet, however, is unsuitable for safety-critical applications due to its lack of delivery guarantees and lack of delay bounds. The Time-Sensitive Networking (TSN) task group proposes several extensions to Standard Ethernet to address these shortcomings. One of the proposed extensions is the Time-Aware Shaper (TAS, IEEE 802.1Qbv-2015) which introduces a gate mechanism that enables scheduled transmissions and minimal jitter for high-priority messages. In order to achieve low jitter for these messages, guard bands are inserted into the schedule of the other traffic classes to ensure that the outgoing link is idle when the transmission of the high-priority message is scheduled to occur. This can result in wasted bandwidth.\u0000 In this work, we propose Size-Based Queuing (SBQ) - an approach to improve bandwidth utilization in TSN networks that utilize TAS and guard bands. After a detailed description of SBQ, we provide a method to schedule an SBQ-enabled TSN network and conduct a qualitative analysis of the impact of SBQ on the transmission time of messages and the improvements on bandwidth utilization. We show that SBQ can reduce the amount of wasted bandwidth in a network, without impacting the transmission of high-priority messages or requiring extensive changes of the TSN network.","PeriodicalId":447904,"journal":{"name":"SIGBED Rev.","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126614523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TSN offers bounded latency for the time triggered (TT) communication by transmitting messages according to a global schedule. Most of the scheduling algorithms in this context provide the solution only from the perspective of scheduling constraints and do not consider the impacts of routing on the scheduling problem. Therefore, these algorithms are not capable to provide effective results in the domain of many real time systems. To address interdependence of routing and scheduling constraints, we introduce a heuristic list scheduler (HLS). Our approach generates valid schedules using joint routing and scheduling constraints in one step. Due to this approach, ability to find feasible schedules is dramatically increased in comparison to the schedulers with fixed routing. In addition, HLS supports multi-cast communication, distributed real time applications and inter-flow dependencies. Experimental results shows the significant increase in the schedulability because of the task and message scheduling combined with routing.","PeriodicalId":447904,"journal":{"name":"SIGBED Rev.","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123304390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with the increased productivity, flexibility, and effectiveness that computers provide, comes the vulnerability to cyber-attacks where software, or even firmware, gets subtly modified by a hacker. The integration of a Trusted Platform Module (TPM) opts to tackle this issue by aiding in the detection of unauthorized modifications so that devices get remediation as needed. Nonetheless, the use of a TPM is impractical for resource-constrained devices due to power, space and cost limitations. With the recent proliferation of miniaturized devices along with the push towards the Internet-of Things (IoT) there is a need for a lightweight and practical alternative to the TPM. This paper proposes a cost-effective solution that incorporates modest amounts of integrated roots-of-trust logic and supports attestation of the integrity of the device's boot-up state. Our solution leverages crypto-acceleration modules found on many microprocessor and microcontroller based IoT devices nowadays, and introduces little additional overhead. The basic concepts have been validated through implementation on an SoC with an FPGA and a hard microcontroller. We report the validation results and highlight the involved tradeoffs.","PeriodicalId":447904,"journal":{"name":"SIGBED Rev.","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115803328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Together they help automate and autonomize the manufacturing processes and controls to optimize the productivity, reliability, quality, cost-effeteness, and safety of these processes. While both visions are promising, developing and operating Industry 4.0 applications are extremely challenging. This is due to the complexity of the manufacturing processes as well as their management, controls, and integration dynamics.

Software-Defined Networking has emerged as an effective network architecture that decouples the control plane and data plane, which makes it capable of handling the dynamic nature of future network functions and intelligent applications while reducing cost through simplified hardware, software, and management.\u0000 This paper presents an SDN architecture for real-time low latency applications that offer adaptive path provisioning based on the calculated end-to-end delay, available bandwidth, and traditional shortest path first algorithm. The SDN architecture utilises the Ryu OpenFlow application programming interface (API) to perform real-time monitoring to collect network statistics and computes the appropriate paths by using this information.
