Instructor: Doug Lea
Class: T-Th 8:00
Office/Lab hours. Normally T-Th 11-12, but send mail at any time with questions or to set up online meeting
Prereqs: CSC241 (365 strongly encouraged) and CSC322 (or 222)
The design, analysis, and implementation of layered computer
networks and networked applications; including underlying
communication support, the development and use of network protocols,
and distributed systems.
- Network Design and Implementation: Layered systems,
point-to-point and shared media, unicast and multicast protocols,
switching, routing, reliable delivery, windowing, congestion
control, security, quality of service.
- Distributed Systems: Remote services, naming,
caching. security, group communication, data consistency, fault
- Analysis: Latency, throughput, messaging overhead, empirical
- Programming: Sockets, cluster and cloud frameworks.
Upon completion of this course, students will demonstrate ability to:
- [Design.] Choose among relevant design strategies to approach
problems; construct and use components and protocols that meet
- [Analysis.] Determine throughput, latency, security,
liveness, and/or fault tolerance properties for a given design and
- [Development.] Incorporate covered techniques when developing
- [Growth.] Learn about and present new ideas and techniques
(and sources) of
Peterson, Larry, and Bruce Davie
Computer Networks: A systems approach.
Lectures mainly follow the text up through chapter 5, but then
on course notes, including:
consensus and fault tolerance,
Subject to minor change:
- Two exams (one during final exam week) (30%)
- Exam questions cover the design and theory of operation of
protocols and components, as well as analysis in terms of
latency, security, liveness, fault tolerance, and appropriateness
for a given problem.
- Exercises (10%)
- When covering non-hands-on topics, some text exercises will be
assigned and discussed in class. Submit in 4 sets:
- Chapter 1
- Chapter 2A
- Chapter 3A (13-17)
- Chapter 3B (47,48)
Chapter 3C (56)
Chapter 3D (73)
- Class presentation (10%)
- An approximately 15 minute presentation on a networking
technology that is covered at most only briefly in class and text.
Example topics include substrates such as radio links, broadband,
and satellites, alternative low-level protocols such as XNS and
Netware, and higher-level frameworks such as JXTA. Time slots for
these will scattered throughout the semester. You can choose to
either do a presentation alone, or together with another student.
- 3 programming assignments (50%)
- At least one project focuses on performance measurement
across multiple hosts and networks; others require specialized
versions of covered techniques and components to develop
network services or systems. Programs may not be submitted
unless they successfully run according to specification.
Two percent credit is taken off per day late.
You must demo within 2 days of submitting. As a substitute for live demos.
you may accompany your program source and screenshots or remote
screenshare of successful operation with a brief (approx
one-page) design and experience account of your approach
and how it changed over time. (This may be embedded as
main program documentation.) If you maintain commit logs
or time logs every time you work on project, a lightly
edited collection of these should suffice. I may send
follow-up questions before accepting.
- Assignment 1
- Assignment 2
- Assignment 3
Here are the targeted topics for lectures, many of them in two or
- Point to Point communication: metrics, errors, APIs
- Shared media communication: ethernet, wireless protocols
- Switching: topologies, protocols
- Routing: paths, metric-based, policy-based (BGP)
- Internetworking: IP, ICMP, ARP, etc
- TCP and related protocols: sessions, windowing, congestion
- RPC: protocols, marshalling
- Naming: DNS, network file systems, etc
- Groups: multicast, consensus protocols, fault tolerance
- Security: policies, authentication, encryption, blockchains
- Application layers: middleboxes, mail, streaming
