Network service practitioners that are poised to handle the strain on the existing limited bandwidth constraints are better placed to be SLA-compliant. The dynamic and time-varying nature of cloud-hosted services require improved techniques to realize accurate models of the systems. To address this challenge: (1) we propose Codec-aware Network Adaptation Agent (cNAA), an online light-weight data learning engine that achieves accurate and correct predictions of quality of delivery (QoD) metrics, namely jitter for video services. cNAA achieves this prediction accuracy by leveraging the available network information in the face of congestion and adaptive codecs; (2) we highlight the short-comings of some baseline machine learning techniques that fail to capture network dynamics and demonstrate their failure in comparison with cNAA; and finally, (3) we demonstrate the efficacy of cNAA under varying network and codec conditions and provide evidence showing that machine learning approaches that incorporate network dynamics are better placed to realize accurate and correct predictions.","PeriodicalId":156419,"journal":{"name":"2020 IEEE 9th International Conference on Cloud Networking (CloudNet)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127394700","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}

Virtual Network Embedding (VNE) that addresses the embedding problems of heterogeneous virtual networks (VNs) onto a physical infrastructure is a main challenge in NV. Network topology attributes and network resource-considered (NTANRC) algorithm is a virtual node mapping mechanism that considers essential network features and global network resources for ranking both substrate and virtual nodes prior to embedding each given virtual network request (VNR). In this paper, we propose NTANRC combined with a distributed parallel Genetic Algorithm (GA) for virtual link mapping, namely NTANRC-GA, to solve online VNE problem. Extensive evaluation results show that our proposed solution not only achieves better performance compared to state-of-the-art VNE algorithms, but also challenges the rapid speed of shortest path (SP) method. NTANRC algorithm and the parallel GA-based algorithm are reverse compliments of each other to achieve an efficient VNE solution.","PeriodicalId":156419,"journal":{"name":"2020 IEEE 9th International Conference on Cloud Networking (CloudNet)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130922962","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}

In this paper, we propose EdgePV, a collaborative computing paradigm to efficiently improve online heterogeneous task scheduling. To guarantee service reliability, a container orchestration (e.g. Kubernetes) is advocated to be integrated into this proposed architecture due to its notable advanced features such as load-balancing, auto-healing, resource isolation, security, etc,. Kubernetes coordinates PVs to run sufficient numbers of task replicas, providing high service availability against possible failure caused by the mobility of PVs. We investigate how efficient PVs can handle the online computational tasks during peak hours. We also present the dual cost and utility-aware heuristic algorithm, compared with a set of heuristics to solve the problem of task scheduling, that can be devised for replacing the default scheduler in Kubernetes platform. Extensive simulation results show that our proposed design improves the task acceptance ratios and average costs at least 23% and 64%, respectively, at lowest task arrival rate compared to the cooperated cloud-edge architecture. Furthermore, owners of PVs can significantly benefit from incentives received by sharing the idle resources of their PVs.","PeriodicalId":156419,"journal":{"name":"2020 IEEE 9th International Conference on Cloud Networking (CloudNet)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116272135","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}

The age of information (AoI) is a new metric recently proposed to capture the data freshness. This paper considers intelligent vehicles in a Vehicle to Infrastructure (V2I) network where each vehicle has a stream of data sampled by on-board sensors to communicate with a road side unit (RSU). Many vehicles demand access and vehicles stay in range for a short period of time. The objective of the RSU, then, is to schedule transmissions of these vehicles with the objective of maintaining data freshness upon receiving these packets. We first formulate the scheduling problem as a mixed integer linear program (MILP) to minimize the weighted AoI, accounting for the dynamic nature of the environment (vehicles' arrivals and their speeds, channel reliability, etc.). We also propose a scalable greedy algorithm that solves the problem in a polynomial time, and we prove that it obtains the optimal solution. We generate synthetic data using SUMO and evaluate numerically the performance of our algorithms.","PeriodicalId":156419,"journal":{"name":"2020 IEEE 9th International Conference on Cloud Networking (CloudNet)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129736554","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}

Cloud users often gain superuser access to cloud machines, which is necessary to customize them to user needs. But superuser access to a vast amount of resources, without support or oversight of experienced system administrators, can create fertile ground for accidental or intentional misuse. Attackers can rent cloud machines or hijack them from cloud users, and leverage them to generate unwanted traffic, such as spam and phishing, denial of service, vulnerability scans, drive-by downloads, etc. In this paper, we analyze 13 datasets, containing various types of unwanted traffic, to quantify cloud misbehavior and identify clouds that most often and most aggressively generate unwanted traffic. We find that although clouds own only 5.4% of the routable IPv4 address space (with 94.6% going to non-clouds), they often generate similar amounts of scans as non-clouds, and contribute to 22–96% of entries on blocklists. Among /24 prefixes that send vulnerability scans, a cloud's /24 prefix is 20–100 times more aggressive than a non-cloud's. Among /24 prefixes whose addresses appear on blocklists, a cloud's /24 prefix is almost twice as likely to have its address listed, compared to a non-cloud's /24 prefix. Misbehavior is heavy-tailed among both clouds and non-clouds. There are 25 clouds that contribute 90% of all the cloud scans, and 10 clouds contribute more than 20% of blocklist entries from clouds.","PeriodicalId":156419,"journal":{"name":"2020 IEEE 9th International Conference on Cloud Networking (CloudNet)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128426129","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}

While the adoption of frameworks like Istio and Kubernetes ease the management and organization of such systems, they do not themselves provide strong observability. Microservice observability requires diverse, highly specialized, and often adaptive, metrics and algorithms to monitor both the health of individual services and the larger application. However, modern metrics collection frameworks are relatively static and rigid. We introduce ViperProbe, an eBPF-based microservices collection framework that provides (1) dynamic sampling and (2) collection of deep, diverse, and precise system metrics. Viper-Probe builds on the observation that the adoption of a common set of design patterns, e.g., servicemesh, enables offline analysis. By examining the performance profile of these patterns before deploying on production, ViperProbe can effectively reduce the set of collected metrics, thereby improving the efficiency and effectiveness of those metrics. To the best of our knowledge, ViperProbe is the first scalable eBPF-based dynamic and adaptive microservices metrics collection framework. Our results show ViperProbe has limited overhead, while significantly more effective for traditional management tasks, e.g., horizontal autoscaling.","PeriodicalId":156419,"journal":{"name":"2020 IEEE 9th International Conference on Cloud Networking (CloudNet)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125919318","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}
