How is the course conducted?
• Please follow the lecture and reading
schedule on course web page
• Assignments are all posted on course web
page (under Lectures)
• Critical dates are posted on the web page
Course Coverage
• Overview of communication networks
– Focus on the Internet
• Will teach networking knowledge
– Pick up concepts, jargons and technologies
• But special attention will be paid to engineering
the network
– Principles and design of the network
– Protocols
– Algorithms
• Always consider: what are the issues and how they
are solved?
Coverage
• Basic: network layers

Application
Transport
Networking
Data Link
• Integrated or advanced topics
– Quality of service framework and mechanisms
– Wireless networks
– Advanced topics: peer-to-peer networks, network
resource allocation
Principles and design
• Most communication networks are giant
infrastructure. A lot is at stake. Need
– Careful and good design, and/or
– Can be evolved
• Objective: what is it used for
– Limited or unlimited?
• What is its architecture?
– Different components and what they do
– How they are realized: implementation and
technologies
• What are the design principles: for coping with
complexity
– To ease designer, implementer, or user’s lives
Protocols and Algorithms
• Algorithms: formal procedure to
accomplishing some task
• Protocols: governs the information
exchange and collective behavior of
distributed entities
– For certain tasks
• Important components in networks
Network Programming
• Learn some network programming
– through project
• But, not a focus.
Why This Course?
• Obvious:
– Learn about the internals of the Internet
– Learn network programming
– Related to other core areas of CS: (distributed)
operating systems
– For some: continue with advanced network courses
• Less obvious: Learn about distributed, complex
systems
– Typical issues, solutions, design and architecture
– Coping with complexity and scale
