Network Systems Design 907721

This course, led by Dr. Ali El-Mousa at the University of Jordan, covers fundamental and advanced networking protocol concepts. Students will engage with real-world protocols, explore design trade-offs, and prepare for advanced research in networking. Core topics include transport protocols (TCP, UDP), IP, routing, and advanced issues like Quality of Service and security. The course includes lectures, informal quizzes, and a research case study. Prerequisites include Computer Networks and familiarity with operating systems.

  1. Network Systems Design907721 http://uojcourses.awardspace.com Dr Ali El-Mousa University of Jordan elmousa@ju.edu.jo

  2. Overview • Introductions:course description & calendar • Answers to frequently asked questions • Prerequisites • Informal Quizzes

  3. Who’s Who • Instructor: • Dr Ali El-Mousa elmousa@ju.edu.jo, Room: CPE 42, Phone: x23003

  4. Course Description: Goals • Fundamental protocol concepts in the context of concrete/real protocols (including protocols that did not survive) • As if YOU designed the protocols grappling through the tradeoffs… • Where do these ideas really come from? • Identify common themes, building blocks… • Look beyond alphabet soups, distinctive differences and silo mindset! • Broad foundation of advanced material of lasting value: you can draw upon them in the future (even in related fields)! • Preparation for possible research/advanced development in networking (reading of papers, fundamental perspective, case-study) • In-class work (informal quizzes) & discussion (be prepared!)

  5. Syllabus • Core problems: heterogeneity, scale, coordination of distributed components, handling failures, sharing resources, managing congestion • Building Blocks: workload units (call vs packet), multiplexing, indirection, virtualization, identifiers/name-space structures/scopes, signaling/state management, randomization, distributed coordination and control, redundancy • Core protocols:Transport (TCP, UDP), IP, Routing, Addressing/Naming. • Advanced topics:Multicasting, Peer-to-Peer, Next-generation IP, Better-than-best-effort Internet (QoS), High-Speed Routers, IP Telephony, Security … (may not cover all)

  6. Course Description Highlights • Lectures • Informal quizzes: Every 2-3 weeks • Be prepared: I will randomly call on students to explain ideas. Grading: • Informal Quizzes & Paper Summaries: {20 pts} • 1 Research Case Study & Presentation: {20 pts} • Mid term Exam {20 pts} • Final exam: {40 pts}

  7. Prerequisites • Required (no exceptions): • CPE-422 Computer Networks or equivalent • Desirable: • Operating Systems • Computer Design (CPE-432 or equivalent) • If you do not have the required prerequisites, you must drop the courseand take it later (next year).

  8. Prerequisites • Protocol Layers: ISO/OSI reference model • Physical Layer: Coding, Manchester • Transmission Media: UTP, Cat 5 • Data Communication: Asynchronous vs synchronous, Baud, bit, and Hz, Half-Duplex vs Full-duplex, Modulation/Demodulation • Packet Transmissions: Framing, Bit stuffing, byte stuffing • Flow Control: On-Off, Window • Error Detection: Parity, Checksum, Cyclic Redundancy Check

  9. Prerequisites (Continued) • Error Recovery: Start and Stop, Go back n, Selective Reject • LANs: Aloha, CSMA/CD, Ethernet, IEEE 802.3, Token Ring/IEEE 802.5, FDDI • Addressing: Unicast/multicast, Local/Global • LAN wiring: 10Base5, 10Base2, 10Base-T, 100Base-TX, • E-LANs: Hubs, Bridges, Routers, Switches • Routing: Distance Vector vs Link State, Spanning tree, source routing • Transport layer: multiplexing, reliability, congestion control, introduction to TCP and UDP • Basics of probability and queuing theory

  10. Answers to FAQ's • Considerable paper readings in the class + research case study (writing skills) • Informal quizzes given every 2-3 weeks • All homework etc due at the beginning of the class indicated as deadline. • Up to one late submission: no penalty • Beyond that 10% penalty • All quizzes are open-book and extremely time limited. • Quizzes consist of design questions, numerical, multiple-choice (true-false), and short answer questions.
