The History, Trend, Types, and Mitigation of Distributed Denial of Service Attacks

Over time, the world has transformed digitally and there is total dependence on the internet. Many more gadgets are continuously interconnected in the internet ecosystem. This fact has made the Internet a global information source for every being. Despite all this, attacker knowledge by cybercriminals has advanced and resulted in different attack methodologies on the internet and its data stores. This paper will discuss the origin and significance of Denial of Service (DoS) and Distributed Denial of Service (DDoS). These kinds of attacks remain the most effective methods used by the bad guys to cause substantial damage in terms of operational, reputational, and financial damage to organizations globally. These kinds of attacks have hindered network performance and availability. The victim’s network is flooded with massive illegal traffic hence, denying genuine traffic from passing through for authorized users. The paper will explore detection mechanisms, and mitigation techniques for this network threat.

交换式以太网中连续实时流媒体的可靠组播

对目前局域网中连续实时流媒体的可靠组播进行了研究.首先分析了局域网影响可靠组播的几个特性,然后设计了局域网内针对连续实时流媒体的基于重传的可靠组播传输协议.协议中的错误恢复首先利用接收者检测包丢失,同时采用NAK(negative acknowledgment)抑制减少产生的反馈包;然后发送者根据NAK请求重传已经丢失的数据包;接收者根据本地播放时间限制决定接收或者丢弃迟到的重传包.实验结果和性能分析证明了该可靠组播协议的可靠性和有效性.

A New Historicism Interpretation of Is He Living or Is He Dead

Is He Living or Is He Dead is mainly about an outstanding painter Francois Millet who pretend to be dead in order to get reputation and money,because at that time a great artist has never been acknowledged until after he was starved and dead. Based on the critic approach of New Historicism, this thesis have analyzed how Millet subvert power and be contained by power, the capitalism and market, which criticized the phenomenon that the value of art is not decided by itself, but by power. No matter it is good or bad, if it is denied by power, it is valueless.

英语论文致谢的英语写作或英译

国际间的科技学术交流广泛采用英语。我国广大科技工作者有许多领先的科技成果,急需向国外交流和推广。越来越多的科技论文投向国际上的英文版学术期刊,为全人类作出贡献。然而,我国许多科技人员由于各种原因,汉译英、英文写作的能力还有限。我国高等院校学报的英文摘要在进入DIAIOG数据库时,往往还要美国学者重新加工,认为错误较多,属中小学水平。其实,还有更多的人连这种水平的文章也写不出来。

Acknowledgment of Libraries in the Journal Literature: An Exploratory Study

Purpose: This study examines acknowledgments to libraries in the journal literature, as well as the efficacy of using Web of Science(WoS) to locate general acknowledgment text.Design/methodology/approach: This mixed-methods approach quantifies and characterizes acknowledgments to libraries in the journal literature. Using WoS's Funding Text field, the acknowledgments for six peer universities were identified and then characterized. The efficacy of using WoS to locate library acknowledgments was assessed by comparing the WoS Funding Text search results to the actual acknowledgment text found in the articles.Findings: Acknowledgments to libraries were found in articles at all six peer universities, though the absolute and relative numbers were quite low(< 0.5%). Most of the library acknowledgments were for resources(collections, funding, etc.), and many were concentrated in natural history(e.g. zoology). Examination of Texas A&M University zoology articles found that 91.7% of the funding information came from "acknowledgments" and not specifically a funding acknowledgment section. The WoS Funding Text search found 56% of the library acknowledgments compared to a search of the actual acknowledgment text in the articles.Research limitations: Limiting publications to journals, using a single truncated search term, and including only six research universities in the United States.Practical implications: This study examined library acknowledgments, but the same approach could be applied to searches of other keywords, institutions/organizations, individuals, etc. While not specifically designed to search general acknowledgments, WoS's Funding Text field can be used as an exploratory tool to search acknowledgments beyond funding. Originality/value: There are a few studies that have examined library acknowledgments in the scholarly literature, though to date none of those studies have examined the efficacy of using the WoS Funding Text field to locate those library acknowledgments within the journal literature.

Enhancing Interest Forwarding for Fast Recovery from Unanticipated Data Access Failure in NDN

We show that an aggregated Interest in Named Data Networking (NDN) may fail to retrieve desired data since the Interest previously sent upstream for the same content is judged as a duplicate one and then dropped by an upstream node due to its multipath forwarding. Furthermore, we propose NDRUDAF, a NACK based mechanism that enhances the Interest forwarding and enables Detection and fast Recovery from such Unanticipated Data Access Failure. In the NDN enhanced with NDRUDAF, the router that aggregates the Interest detects such unanticipated data access failure based on a negative acknowledgement from the upstream node that judges the Interest as a duplicate one. Then the router retransmits the Interest as soon as possible on behalf of the requester whose Interest is aggregated to fast recover from the data access failure. We qualitatively and quantitatively analyze the performance of the NDN enhanced with our proposed NDRUDAF and compare it with that of the present NDN. Our experimental results validate that NDRUDAF improves the system performance in case of such unanticipated data access failure in terms of data access delay and network resource utilization efficiency at routers.

Research on Key Technologies of Electronic Shelf Labels Based on LoRa

The demand for Electronic Shelf Labels(ESL),according to the Internet of Things(IoT)paradigm,is expected to grow considerably in the immediate future.Various wireless communication standards are currently contending to gain an edge over the competition and provide the massive connectivity that will be required by a world in which everyday objects are expected to communicate with each other.Low-Power Wide-Area Networks(LPWANs)are continuously gaining momentum among these standards,mainly thanks to their ability to provide long-range coverage to devices,exploiting license-free frequency bands.The main theme of this work is one of the most prominent LPWAN technologies,LoRa.The purpose of this research is to provide long-range,less intermediate node,less energy dissipation,and a cheaper ESL system.Much research has already been done on designing the LoRaWAN network,not capable to make a reliable network.LoRa is using different gateways to transmit the same data,collision,data jamming,and data repetition are expected.According to the transmission behavior of LoRa,50%of data is lost.In this paper,the Improved Backoff Algorithm with synchronization technique is used to decrease overlapping and data loss.Besides,the improved Adaptive Data Rate algorithm(ADR)avoids the collision in concurrently transmitted data by using different Spreading Factors(SFs).The allocation of SF has the main role in designing LoRa based network to minimize the impact of the intra-interference,cost function,and Euclidean distance.For this purpose,the K-means machine learning algorithm is used for clustering.The data rate model is using an intra-slicing technique based on Maximum Likelihood Estimation(MLE).The data rate model includes three critical communication slices,High Critical Communication(HCC),Medium Critical Communication(MCC),and Low Critical Communication(LCC),having the specified number of End devices(EDs),payload budget delay,and data rate.Finally,different combinations of gateways are used to build ESL for 200 electronic shelf labels.

Chinese Students' Learning Styles & Strategies in the IELTS“Speaking& Writing”Preparation

如何完善自己的英语书面表达

自我们从小学认字开始,到我们笨拙的拿起笔开始写作文,语文教师就一直告诉我们,如何写好一篇文章。好的文章是由许多个段构造成的。段与段之间又是由过渡语、过渡词连接起来的。每篇文章都应该有其大意,每个段落有其段落大意而且它们都是围绕着整篇文章的中心大意展开的,都是服务于作者想表达的中心思想的话题之间是有关联的。段与段之间自然的过渡的流畅的衔接使得文章如行云流水,清新脱俗。那么。
