This wastes bandwidth, the most expensive resource of the browser-server communication. To solve this issue, header compression for HTTP/2 was standardized. During the standardization, we found that one element of the compression technology, the so called reference set, contributes little to the compression ratio while its mechanism is complicated. With our proposal, the reference set was removed and the specification and implementations were drastically simplified. For high performance implementation of header compression, we devised token-based reverse indices, length guessing for Huffman encoding, and pre-calculated state transitions for Huffman decoding.","PeriodicalId":209819,"journal":{"name":"Proceedings of the 12th International Conference on Future Internet Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121331646","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}

Hayabusa uses SQLite, standard lightweight database software with GNU Parallel and general Linux commands, such that it can run efficiently without complex components. Network administrators can use Hayabusa to accumulate and store log information at high speeds and to search the logs quickly. In our experiments, Hayabusa required only 8 seconds to convert 1.2 M log messages into a database file. Moreover, Hayabusa required only 5 seconds to search a keyword from 1.7 billion records. Hayabusa achieved high-performance search speed in a stand-alone environment without a complex distributed environment. Compared with the distributed environment, Spark, the proposed stand-alone Hayabusa was approximately 27 times faster.","PeriodicalId":209819,"journal":{"name":"Proceedings of the 12th International Conference on Future Internet Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133607066","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}

It is assumed that it is a key enabler for other technologies such as smart cities, smart health, smart grids, and smart transportation. Although the concept of the IoT is generally understood among researchers, there is no standard model representing this technology, particularly with respect to network architecture, which will be necessary to apply existing and emerging resilience and survivability techniques. Additionally, security and privacy have not yet received the needed attention. In this paper we propose a new multilevel IoT network-centric model, and discuss its applicability to the application of resilience and survivability.","PeriodicalId":209819,"journal":{"name":"Proceedings of the 12th International Conference on Future Internet Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123014086","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, periodic polling for flow statistics cannot well balance the tradeoff between measurement accuracy and limited control channel bandwidth. To further discuss the resource/accuracy tradeoff, this paper extends OpenFlow protocol to add sampling action for each monitoring flow entry, and systematically sample the matching packets to infer the flow-level statistics. Although traffic sampling can somehow be error-prone, it will provide near-real-time measurements of flow dynamics and determine its accurate polling frequency, which the polling-based approach cannot achieve. In this paper, we propose a per-flow sampling solution to instruct the controller to adaptively adjust polling frequency, then evaluate it in the context of link utilization monitoring.","PeriodicalId":209819,"journal":{"name":"Proceedings of the 12th International Conference on Future Internet Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127953775","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}

Recently, methods for monitoring latency have been introduced. Most of these methods monitor end-to-end path delay (per path) by sending probes requests along the path. These methods led to redundant work and network overhead, which resulting from monitoring multiple paths between each pair of nodes. Moreover, end-to-end probes cannot monitor the delay on path segments (per link) between arbitrary network devices. However, measuring per link delay is challenging. In this paper, we propose a method to measure per link delay in real-time to efficiently apply QoS policies, our method does not require any complementary support from the switching hardware and can avoid redundant work and network overhead. We validate our method using the popular Mininet network emulation environment with Pox controller.","PeriodicalId":209819,"journal":{"name":"Proceedings of the 12th International Conference on Future Internet Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128029551","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 temporal evolution of the routing table size has been researched to anticipate the memory limitation of BGP routers. However, route aggregation and compression techniques make it difficult to expect the actual memory size from the routing table size. Therefore, further evolution models focusing on the spatial routing table structure are required to evaluate the tolerance of these techniques to future routing table growth. In this paper, we create an evolution model focusing on spatio-temporal route changes using ten-year BGP routing table datasets. We categorize route variations into three types; new, fragmented, and vanished and then create a model for each type. We also demonstrate the characteristics of the model parameters in these ten years.","PeriodicalId":209819,"journal":{"name":"Proceedings of the 12th International Conference on Future Internet Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121561612","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}

CDN (Content Distribution Networks) has been a popular architecture compatible with the current Internet, and a new revolutionary paradigm such as ICN (Information Centric Networking) has studied. One of the main components in both CDN and ICN is considering cache on network. Despite a surge of extensive use of cache in the current and future Internet architectures, analysis on the performance of general cache networks are still quite limited due to complex inter-plays among various components and thus analytical intractability. Due to mathematical tractability, we consider 'static' cache policies and study asymptotic delay performance of those policies in cache networks, in particular, focusing on the impact of heterogeneous content popularities and nodes' geographical 'importances' in caching policies. Furthermore, our simulation results suggest that they perform quite similarly as popular 'dynamic' policies such as LFU (Least-Frequently-Used) and LRU (Least-Recently-Used). We believe that our theoretical findings provide useful engineering implications such as when and how various factors have impact on caching performance.","PeriodicalId":209819,"journal":{"name":"Proceedings of the 12th International Conference on Future Internet Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122878560","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}
