Autonomic Computing brings many concepts quite useful in the construction of elastic cloud computing solutions, such as control loops and thresholds-based rules. This paper proposes an elastic architecture for cloud computing based on concepts of Autonomic Computing. For its validation, we designed two experiments using microbenchmarks, applied in both private and hybrid clouds. Results shown cloud computing and Autonomic Computing may work well together in the elasticity provisioning.","PeriodicalId":220543,"journal":{"name":"2015 Latin American Network Operations and Management Symposium (LANOMS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124971542","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}

Nevertheless, virtualized structures are as failure-prone as their underlying physical infrastructure. Hence, dependability attributes constitute relevant metrics for virtual network allocation decisions. This work proposes and evaluates a greedy solution to mapping virtual networks that is a well-known NP-Hard problem. We take into account a dynamic networking scenario where the time to map requests and availability are important factors. Results show that the proposed heuristic achieves an availability above 99% in the different scenarios simulated.","PeriodicalId":220543,"journal":{"name":"2015 Latin American Network Operations and Management Symposium (LANOMS)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116390907","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}

To be economically doable, virtualized datacenters must reach a high level of resource utilization by simultaneously hosting as many tenants as possible. Traditional network virtualization techniques do not scale to accomplish those requirements. Furthermore, new demands are arising like programmable networks leveraged by the Software-Defined Networking (SDN) paradigm. This paper introduces HotOM, a network multi-tenancy approach to overcome traditional limitations through redefining a L2 header purpose and introducing a new L2.5 shim protocol, preserving legacy network core's device.

In effect, a Network for Experimentation allows an experimenter to configure instantiate, run and collect measurements of distributed experiments on top of a testbed managed by a Control and Monitoring Framework (CMF). Recent Network for Experimentation deployments are Multi-CMF testbeds in which various existing CMFs are integrated in order to achieve a larger set of supported applications and services. This paper describes a distributed and federated storage solution for monitoring data in a Multi-CMF scenario (FIBRE testbed). The solution adopts a distributed iRODS-based monitoring data storage scheme, supporting data distribution and federation across islands (institutions) implementing the testbed. A distributed and transparent data storage facility among multiple native database systems was implemented supporting real-time and persistent monitoring data storage.

These networks allow greater mobility and comfort for its users, and provide multiple access and satisfactory transfer rates. These networks also became popular due to the low cost of its operational infrastructure, partly by the use of unlicensed bands, of free and public use. The widespread use of these frequency bands cause the interference from signals transmitted by multiple devices, resulting in the need of spectral analysis to obtain a local frequency spectrum diagnosis, thus providing a more effective use of it.

While research has pushed technology to deliver more powerful information discovery algorithms, and responsive on-demanding storage and processing capacity through data analysis and distributed cloud infrastructure, concerns about privacy have globally raised several discussions involving different sectors of the society. In particular, individual rights are highly impacted by privacy issues due to nowadays geographic distribution of sensitive information and its discovery. In this work, we present a model for privacy awareness during the data analytics process in a context of scalable computing using the cloud. Our approach addresses privacy issues both in data analytics process and in the infrastructure resource allocation according to privacy regulation in Service Level Agreements (SLA). The proposed model for Privacy-Aware Information Discovery (PAID-M) provides privacy awareness by executing data analytics algorithms encapsulated with privacy preserving techniques. The model also presents how it intends to address the privacy issue in the cloud deployment process by considering differences in privacy regulations and jurisdictions.","PeriodicalId":220543,"journal":{"name":"2015 Latin American Network Operations and Management Symposium (LANOMS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115152099","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 work evaluates the OpenFlow performance in scenarios with based commodity wireless router running an Open vSwitch (OVS) Linux kernel module and different SDN controllers. A set of client hosts connected at the commodity wireless router sends data to a sink server host. We collected key performance metrics, such as throughput, delay, jitter, and packets loss, to evaluate the efficiency of using a commodity wireless router in a SDN context. Results show some bottleneck when using UDP protocol in high rates. These results suggest that a commodity wireless router can be only deployed in reduced size networks, as homes and small to medium organizations, contributing to accelerate the pace of SDN adoption based on use of legacy network devices.","PeriodicalId":220543,"journal":{"name":"2015 Latin American Network Operations and Management Symposium (LANOMS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123134859","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}
