MET CS 535 Computer Networks
This course provides a robust understanding of networking. It teaches the fundamentals of networking systems, their architecture, function and operation and how those fundamentals are reflected in current network technologies. Students will learn the principles that underlie all networks and the application of those principles (or not) to current network protocols and systems. The course explains how layers of different scope are combined to create a network. There will be a basic introduction to Physical Media, the functions that make up protocols, such as error detection, delimiting, lost and duplicate detection; and the synchronization required for the feedback mechanisms: flow and retransmission control, etc. Students will be introduced to how these functions are used in current protocols, such as Ethernet, WiFi, VLANs, TCP/IP, wireless communication, routing, congestion management, QoS, network management, security, and the common network applications as well as some past applications with unique design solutions. Prereq: MET CS 575 and MET CS 201 or MET CS 231 or MET CS 232. Or instructor's consent. Restrictions: This course may not be taken in conjunction with MET CS 625 or MET CS 425 (undergraduate). Only one of these courses can be counted towards degree requirements. [ 4 cr. ]

MET CS 635 Network Media Technologies
The purpose of this course is to provide students with a deeper understanding of Media-specific Technologies not only so that they will be able to use the ones covered in this course, but more importantly be able to analyze and evaluate new technologies. This course applies the principles from CS 535 to understand the engineering that lead to them as well as the special problems that confront network technologies that operate directly over the physical media. These Media specific layers have three problems to solve: the usual one of multiple users of a common resource, accommodating the particular characteristics of the media, and providing (to the degree possible) a media- independent service to the layers above. While CS 535 provides a high-level view of some of these technologies, in this course, they are considered in much greater detail as to how these technologies address their requirements and take advantage of the assumptions made. The emphasis is on those technologies that are either representative of a type or take a unique perspective on the problem. Hence, the traditional data link protocols, such as HDLC, modern Ethernet (primarily VLANs), WiFi (802.11) represent the first type, while media technologies, such as DOCSIS, RFIDs, IoT, and cellular mobile networks are representative of the second. The course will consider how these technologies solve mobility, routing, congestion, QoS (multi-media), security, etc. A major project is part of this course. Prereq: MET CS 231 or MET CS 232 and either MET CS 625 or MET CS 535; or instructor's consent. [ 4 cr. ]

MET CS 775 Advanced Networking
The purpose of this course is to provide a solid foundation for the networking practitioner. While CS 535 introduces the basic networking concepts, this course provides the deep understanding that the practitioner who may be developing or evaluating network products needs to know. Consequently, this course does a much 'deeper dive' into the topics that tend to be the most counter-intuitive such as naming and addressing, synchronization, congestion management and routing. Naming and addressing is the least understood topic in networking and the most important. This topic is not covered in any current textbooks. The student will explore why the necessary and sufficient condition for synchronization for reliable data transfer is to bound 3 timers and independent of message exchanges. This is not at all obvious and has deep implications for protocols. To engineer networks, it is important to understand the degree to which the behavior of error and flow control protocols can be modified and to what purposes. Congestion management is the second least understood topic in networking. The course emphasizes congestion avoidance as opposed to congestion control and explores the impact in different environments. Routing is the third least understood topic in networking. This course is most concerned with its role in resource allocation but also that "routing protocols" are really distributed database protocols. In addition, the course will consider the interactions among these topics and the necessity of keeping the system effects in perspective. Prereq: MET CS 535; or instructor's consent. [ 4 cr. ]
Students who have completed courses on core curriculum subjects as part of their undergraduate degree program or have relevant work-related experience may request permission from the Department of Computer Science to replace the corresponding core courses with graduate-level computer science electives.
