However, it involves a mapping step that is manual and tedious. There exist techniques and tools that attempt to automate mapping, yet they are either limited in their approach or they require an initial set of manually pre-mapped entities. This study proposes a novel technique, InMap, that improves the mapping process in reflexion modelling by both providing versatility and eliminating the constraint of needing a set of manually pre-mapped entities in order to automate mapping. Using a software’s architecture descriptions, InMap applies information retrieval concepts to the software’s source code to interactively provide mapping recommendations to an architect. For the six systems InMap was evaluated on, the recommendations it provided achieved an average recall of 0.97, and an average precision of 0.82. InMap also achieved higher, f1-scores in comparison to existing techniques that require premapping. This provides a basis for improving industry tools that use reflexion modelling or similar SACC methods.","PeriodicalId":284628,"journal":{"name":"2021 IEEE 18th International Conference on Software Architecture (ICSA)","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124707714","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}

This paper provides a quantitative evaluation of different architectural patterns that can be used for cyber-physical systems to understand which patterns are more suitable under some peculiar characteristics of dynamic spaces, e.g., frequency of obstacles in paths. We use stochastic performance models to evaluate architectural patterns, and we specify the dynamic aspects of the physical space as probability values. This way, we aim to support software architects with quantitative results indicating how different design patterns affect some metrics of interest, e.g., the system response time. Experiments show that there is no unique architectural pattern suitable to cope with all the dynamic characteristics of physical spaces. Each architecture differently contributes when varying the physical space, and it is indeed beneficial to switch among multiple patterns for an optimal solution.","PeriodicalId":284628,"journal":{"name":"2021 IEEE 18th International Conference on Software Architecture (ICSA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127020771","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}

Commercial IoT applications have high reliability requirements for messaging, as lost messages due to unstable Internet connections or node failures can harm devices or even human beings. MQTT brokers implement numerous architectural availability tactics, but former analyses of MQTT communication have mainly focused on performance measurements under stable conditions. We have created the MAYHEM resilience testing tool for MQTT brokers and applied it in various resilience experiments on different MQTT brokers (VerneMQ, Mosquitto, HiveMQ, EMQ X). We found that MQTT QoS level 0 is already robust against minor packet loss, that selected broker message persistency solutions can lead to lost messages, and that most clustered MQTT brokers favor availability and performance over communication integrity. The results can support IoT practitioners in architectural decisions and researchers as well as broker vendors in optimizing designs and implementations.","PeriodicalId":284628,"journal":{"name":"2021 IEEE 18th International Conference on Software Architecture (ICSA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115264085","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}

They instantiate the services that frameworks provide to implement various architectural tactics and patterns. One of the challenges in employing frameworks for such tasks is the difficulty of learning and correctly using the APIs of the frameworks. This paper introduces a learning-based approach called ARCODE to help novice programmers correctly use frameworks’ APIs to implement architectural tactics and patterns. ARCODE has several novel components: a graph-based approach for learning specification of a framework from a limited number of training software, a program analysis algorithm to eliminate erroneous training data, and a recommender module to help programmers use APIs correctly and identify API misuses in their program. We evaluated our technique across two popular frameworks: JAAS security framework used for authentication and authorization tactic and Java RMI framework used to enable remote method invocation between client and server and other object oriented patterns. Our results demonstrate (i) the feasibility of using ARCODE to learn the specification of a framework; (ii) ARCODE generates accurate recommendations for finding the next API call to implement an architectural tactic/pattern based on the context of the programmer’s code; (iii) it accurately detects API misuses in the code that implements a tactic/pattern and provides fix recommendations. We also demonstrate that ArCode outperforms two famous techniques, MAPO and GrouMiner, on API recommendation and misuse detection tasks.","PeriodicalId":284628,"journal":{"name":"2021 IEEE 18th International Conference on Software Architecture (ICSA)","volume":"6 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132290997","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}

At the same time, organizations working on Systems of Systems have been developing solutions for closing this gap for many years now. This work aims to extract such knowledge from practitioners by studying the case of a large-scale scientific instrument, a geographically distributed radio telescope to be more specific, developed as a sequence of projects during the last two decades. As the means for collecting data for this study we combine online interviews with a virtual focus group of practitioners from the organization responsible for building the instrument. Through this process, we identify persisting problems and the best practices that have been developed to deal with them, together with the perceived benefits and drawbacks of applying the latter in practice. Some of our major findings include the need to avoid over-reliance on the flexibility of software to compensate for incomplete requirements, hidden assumptions, as well as late involvement of system architecting, and to facilitate the cooperation between the involved disciplines through dedicated architecting roles and the adoption of unifying practices and standards.","PeriodicalId":284628,"journal":{"name":"2021 IEEE 18th International Conference on Software Architecture (ICSA)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117305875","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}
