Spring: 3.0 hours of lecture and 1.0 hours of discussion per weekįall: 3.0 hours of lecture and 1.0 hours of discussion per weekįinal exam status: Written final exam conducted during the scheduled final exam periodĬourse objectives: This course introduces the operating and design principles of the Internet and its associated technologies. The topics include graph theory, Markov chains, queuing, optimization techniques, the physical and link layers, switching, transport, cellular networks and Wi-Fi. The course covers both the architectural principles for making these networks scalable and robust, as well as the key techniques essential for analyzing and designing them. Yuanfeng Wen is student from US Berkeley.Catalog Description: This course focuses on the fundamentals of the wired and wireless communication networks. Note: For (a) you need to explain only the main ideas. Use no more than three phrases to describe each goal. Use no more than five phrases for the explanation. Yilei Fu and Lihang Gong are concurrent enrollment student in UC Berkeley from Harbin Institute of Technology, China. EE122 Midterm 2 Exam Prof: Lai, Stoica UC Berkeley, Fall 2001 Question 1 (20 pt) (a) (10 pt) What is RED Explain briefly how it works. To get started, you will implement alearning switch,1 which learns the location of hosts bymonitoring traffic. Our programming language is Python (3.5.2), 64bit. You will implement code to run at a router, and we willprovide arouting simulator that builds agraph connecting your routers to each other andsimulated hosts on the network. We cannot possibly finish this project if we did not receive Professor Shyam Parekh’s project reference, and we are grateful for his wonderful course this semester. We raise an overview of several future perspectives, like combining Fat-Tree structure and BCube structure. Then, we found the Fat-Tree structure also have some drawbacks, which impelled us to find more new structures and new algorithms. Also we applied flow classification and flow rearrangement on this data center topology. In our teamwork, we simulated a special data center topology: Fat-Tree and applied its routing algorithm. The network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Today’s data centers may contain tens of thousands of computers with significant aggregate bandwidth requirements. EE122Project Topic: Commodity Data Center Network Arch ![]()
