CSCD 433/547Advanced Computer Networks

• Lecture 1
• Course Overview
• Winter 2009

2
The Course

• CSCD 433/547
• 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 since they are
  graduate students

3
The Course

• CSCD 433/547
• Mainly an advanced network class with some
  network programming
• What does that mean?
• Look at the Goals and Learning Objectives

4
Goals for the Course

• Learn about networks as systems including design
  principles, performance, software and hardware
  components, and underlying protocols.
• To explore Quality of Service (QOS) features of
  networks including protocols
• Continue learning network programming

5
Learning Objectives

• Study the 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

6
Learning Objectives Continued

• Study applications that require QOS features and
  learn which protocols support them
• Write network programs to better understand
  network concepts

7
Importance of Networks

• Networks are one of the most important thing you
  will study in CS
• How useful is a standalone computer in todays
  world?
• Computing devices once were mostly standalone,
  separate entities
• Main purpose was computing, storing and
  processing large amounts of data
• Used by government, universities and corporations
• Networks created originally to exchange
  information between researchers and government
  entities

8
Importance of Networks

• Networks are ubiquitous
• Fun to look at Internet Maps
• Here is a unique black and white set of Internet
  connection maps

Book Perspective

• Textbooks
• Expensive
• What are they good for?

20
Book Perspective

• What are the usefulness of Textbooks?
• Offer a guide to the topics
• Whats important / whats not important
• Authors typically have years of experience
• This textbook has a definite perspective a
  Systems Approach to Networks

21
Book Perspective

• Principles
• Thought process led to todays 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
• P2P, VOIP, Real time service

22
Book Perspective

• Network Behavior
• How does the integration of hardware/software
  affect behavior?
• Can network behavior be predicted
• Compare to Other Systems
• OSs, distributed systems, other software
  architecture systems
• All are complex and rely on design principles
• Useful to examine common elements of complexity
