However, the introduction of DNSSEC has an impact in the operational workflow of DNS systems: (i) signatures have an expiration date, hence the records must be periodically signed and (ii) key management tasks can be overwhelming. These are problems specially for DNS zones with several records (for instance a Top Level Domain). The adoption of Hardware Security Module (HSM) is an option to provide highly secured keys and signature management. Nevertheless HSM is expensive and hardware can fail. We present a novel system based on threshold cryptography, called Poor Man's Hardware Security Module (pmHSM), which provides the signature components of an HSM over inexpensive commodity hardware to support the operational signing workflow of DNSSEC. This approach significantly improves security and availability of the overall system since the secret key is left beyond the reach of malicious compromises, it is spread among several independent nodes of the system.","PeriodicalId":161093,"journal":{"name":"Proceedings of the 9th Latin America Networking Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132626062","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}

Due to the randomness of customer requests, the Virtual Machine Placement (VMP) should be formulated as an online optimization problem. This work presents a formulation of a VMP problem considering the optimization of the following objective functions: (1) power consumption, (2) economical revenue, (3) quality of service and (4) resource utilization. To analyze alternatives to solve the formulated problem, an experimental comparison of five different online deterministic heuristics against an offline memetic algorithm with migration of VMs was performed, considering several experimental workloads. Simulations indicate that First-Fit Decreasing algorithm (A4) outperforms other evaluated heuristics on average. Experimental results prove that an offline memetic algorithm improves the quality of the solutions with migrations of VMs at the expense of placement reconfigurations.","PeriodicalId":161093,"journal":{"name":"Proceedings of the 9th Latin America Networking Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132893845","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 model, either routers or user devices in the network are capable of storing content in cache, where a client device pull a content by expressing an interest of the desired content name. One of the most sucessfull implementation of ICN is Content-Centric Networking (CCN) proposed by PARC. In CCN, the forwarding strategy pushes interest packets torwards a content server through a route determined by the Shortest-Path Route (SPR) strategy. However, SPR cannot fully exploit the network caching benefits, because the caching process only happens within the path without considering cache saturation level. Therefore, we propose Least Cache Routing (LCR) cache-aware strategy. Besides being based on SPR, LCR is constantly looking for the least saturated paths. The results shows that, a slight improvement on forwarding strategy is capable of improving LCE and LCD cache decision policies. Our results shows 150% and 53% performance gain on cache hit probability when LCR is jointly running with, respectively, LCE and LCD on Torus network.","PeriodicalId":161093,"journal":{"name":"Proceedings of the 9th Latin America Networking Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131589682","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}
