Computer networks / Andrew S. Tanenbaum, Nick Feamster, D. Wetherall Harlow, United Kingdom : Pearson, 2021 946 pages. : illustrations (black and white) ; 28 cm. Ký hiệu phân loại (DDC): 004.6 In Computer Networks,Tanenbaum et al. explain how networks work from the inside out. They start with the physical layer of networking, computer hardware and transmission systems,then work their way up to network applications. Each chapter follows a consistent approach: The book presents key principles, then illustrates them utilizing real-world example networks that run through the entire book - the Internet, and wireless networks, including Wireless LANs, broadband wireless,and Bluetooth. The 6th edition is updated throughout to reflect the most current technologies, and the chapter on network security is rewritten to focus on modern security principles and actions.Tutorial videos on key networking topics and techniques are available to students on the companion website at www.pearsonglobaleditions.com Số bản sách:

Performance evaluation using multiple controllers with different flow setup modes in the software defined network architecture / Suad El-Geder [Great Britain] : Brunel University London, 2017 119 pages. : illustrations ; cm. Ký hiệu phân loại (DDC): 004.6 In this thesis, a scheme of using multiple controllers which handle multiple network devices has been proposed, while using OpenFlow controllers in the proactive operations paradigm, and this in order to face the problem of using a single controller in the SDN model, including the lack of reliability and scalability on such a model. The main characteristic of this new approach are focused on the ability to design a dynamic and highly programmable network, moving the intelligence from the underlying systems to the network itself through a controller. To evaluate the proper effects of this new approach, different dynamic and programmable networks that could simulate real scenarios and measure their performance contrasting the obtained results with the pragmatic theory has been implemented. The SDN (Software-Defined Network) controller (Open Daylight), has been utilized, and thoroughly examined. Số bản sách:
