In the rising tide of the Internet of things, more and more things in the world are connected to the Internet. Recently, data have kept growing at a rate more than four times of that expected in Moore＇s law. This explosion of data comes from various sources such as mobile phones, video cameras and sensor networks, which often present multidi- mensional characteristics. The huge amount of data brings many challenges on the management, transportation, and pro- cessing IT infrastructures. To address these challenges, the state-of-art large scale data center networks have begun to provide cloud services that are increasingly prevalent. How- ever, how to build a good data center remains an open chal- lenge. Concurrently, the architecture design, which signifi- cantly affects the total performance, is of great research inter- est. This paper surveys advances in data center network de- sign. In this paper we first introduce the upcoming trends in the data center industry. Then we review some popular design principles for today＇s data center network architectures. In the third part, we present some up-to-date data center frame- works and make a comprehensive comparison of them. Dur- ing the comparison, we observe that there is no so-called op- timal data center and the design should be different referring to the data placement, replication, processing, and query pro- cessing. After that, several existing challenges and limitations are discussed. According to these observations, we point out some possible future research directions.

Data mining involves analysis, extraction, refining and representation of required data from large databases. kDCI (k Direct Count and Intersect) algorithm is one of the best scalable algorithms for identifying frequent items in huge repository of data. This algorithm uses a special kind of compressed data structure which helps in mining the datasets easily. Apriori algorithm, a realization of frequent pattern matching, is universally adopted for reliable mining. It is based on parameters namely support and confidence. kDCI algorithm is hybridized with Apriori algorithm for better performance than their individual contribution. The result proves scalability and mining speed effectively.
In this paper, we propose an efficient code-based 1-out-of-N oblivious transfer, OT1N, based on McEliece assumptions without invoking the OT12 several times as in the paradigm proposed in [20,6]. We also show that the...
