The Importance Of Big Data With Computer Networks - 729 Words

When Big Data meets Computer Networks , designing and managing the IT infrastructure become a non-trivial and a challenging task . Over the past few years , the increasing traffic volumes and the greater emphasis on network reliability , scalability and speed led to the rise of new networking trends such as Cloud Computing . However , the size and the scope of the networks continue to increase tremendously which increase the complexity and the difficulty of computer networks management . As we know , the configuration task is still executed according to individual protocols and configuration interfaces which make it very laborious and slow . Moreover , The Proliferation of manufacturers and the non-feasibility of eradicating legacy†¦show more content†¦In addition to the network devices heterogeneity , the recent specifications of OpenFlow specify more than 40 fields in a forwarding rule header . Hence , adapting the packet processing pipeline to one of the data plane elements is a non-trivial task. On the other hand , designing a packet classification scheme is not only constrained by the hardware architecture but also by the frequent changes in the network state . That is to say , the packet classification should always guarantee the end-users applications requirements in terms of traffic priority , bandwidth and latency . Within this context, we conducted our graduation project . We make use in this work of packet processing challenges in regards with OpenFlow/SDN requirements to build a framework for an optimal packet classification . Our framework pre-processes OpenFlow rules by investigating the relation between rules and then generates a packet classification schemes which are aware of the underlying hardware architecture and also network services priorities . Added to that , the framework communicates with the target physical platform in order to map the computed classification structure and place the the OpenFlow rules . \newline We tested our Framework by evaluating the performances of two backends : a hardware-based switch and a software-based switch. The remainder of this report is structured as follows. In Chapter 1, we willShow MoreRelatedDifference Between Open And Open Source Software1614 Words   |  7 Pagesinternal and external attack vectors; it can also stem from lack of knowledge. Free and open source software offer significate benefits to an organization, which can also pose a risk that can allow attackers to gain access to vital information on the network server. Many security professionals use open source software to fast-track transport of digital content. Open source application has many drawbacks, the fact that public source application is free for anyone to use and possible alter.
