  1. CSCD 433/533Advanced Computer Networks Lecture 1 Course Overview Fall 2013

  2. The Course • CSCD 433/533 • Combination Senior/Graduate Student class • As seniors, you are expected to know a lot • Graduate students are expected to know more! • Class will accommodate both groups • Graduate students will do more • More about what that means later ...

  3. The Course • CSCD 433/533 • Advanced network class with some network programming • Goals and Learning Objectives

  4. Goals for the Course • Learn about networks as systems • There are fundamental design principles for networks • Performance, • Software and hardware components, and • Underlying protocols • Explore Quality of Service (QOS) features of networks including protocols • Continue learning network programming

  5. Quality of Service • Different applications have different requirements for handling their network traffic • Applications generate traffic at varying rates • Generally require networks to carry traffic at the rate at which they generate it • We will learn how networks handle this

  6. Learning Objectives • Study design principles of the Internet as an example of a successful network that scales • Read and discuss papers • Learn about network performance, how to perform measurement and tools • Study some specific software and hardware components and understand how they work

  7. Learning Objectives Continued • Study applications that require QOS features and learn which protocols support them • For example: Streaming Media, Internet phones • Write network programs to better understand network concepts

  8. Importance of Networks • Networks are one of the most important things you will study in CS • How useful is a standalone computer in today’s world? • Computing devices once were mostly standalone, separate entities • Networks created originally to exchange information between researchers and government entities

  9. Importance of Networks • Networks are ubiquitous • Fun to look at Internet Maps • Here is a unique black and white set of Internet connection maps http://www.chrisharrison.net/projects/ InternetMap/index.html

  10. Internet Growth Internet growth is exponential!! Growth of Internet Hosts 7/2008 570,937,778 7/2007 489,774,269

  11. Topics Covered

  12. Topics Covered • CSCD 330 • OSI Model • Layered architecture, purpose of layers • Layers • Link – Ethernet, Network – IP, Transport – TCP,UDP, Applications – HTTP, SMTP, DNS • Routing • Routers, algorithms – introduction to BGP, OSPF • Reliable transport, principles for that • Socket programming – Java • P2P and Wireless

  13. Topics Covered • CSCD 433/533 • Network design • How do you design a network? • Are there fundamental properties that most networks must exhibit? • What are the factors that affect performance and how do you design for them?

  14. Topics Covered • CSCD 433/533 • Routing • Routers - performance, details • Algorithms – more about performance • Multi Protocol Label Switching (MPLS)‏ • Multicast • Virtual Private Networks (VPNs)‏ • Tunnels

  15. Topics Covered • CSCD 433/533 • Resource Allocation • Congestion Control • Quality of Service • Real time Protocol – RTP • Wireless, mostly 802.11 • Other topics • Network programming

  16. Course Structure • CSCD 433 – Grads and Undergrads • M, W, F – Lecture Tues, Thu - Labs Lab Details • GNS3 Cisco Simulation software • Programming exercises • Some other Lab tools

  17. Course Structure • CSCD 433 – Grad Students • 1. Survey Paper or • 2. Create a Lecture (or Lab) • Must clear the idea with me • Need to sign up ahead of time • I have topic suggestions

  18. Assignments • CSCD 433/533 • Programs • Several programs - about 2 • Homework • Homework – some problems from text • Short Writing Assignments

  19. Assignments • CSCD 433/533 • Tests - takehome • Final (maybe optional)‏ • In-class Participation • Make sure you come to class • Make sure you talk !!! • Make sure I know your name

  20. Book Perspective • Textbooks • Expensive … • What are they good for?

  21. Book Perspective • What are the usefulness of Textbooks? • Offer a guide to the topics • What’s important / what’s not important • Authors typically have years of experience • Tanenbaum textbook is in its 5th edition • Updated network information

  22. Book Perspective • From reading you get ... • Principles • Thought processes led to today’s networks • If understand principles, then can understand new proposed protocols • Software • Important to allow networks to provide new services • Software allows new services to be provided with existing hardware - cheaper, easier • P2P, VOIP, Real time service

  23. Book Perspective • Network Behavior • How does the integration of hardware/software affect behavior? • How do you predict network behavior? • Compare to Other “Systems” • OS’s, distributed systems, other software architecture systems • All are complex and rely on design principles • Useful to examine common elements of system complexity • How to simplify these?
