Base Knowledge

The following are Recommended Basic Knowledge (organized by course):

  • Introduction to Communication Networks (TCP/IP networking stack basics and Berkeley sockets programming);
  • Routing Protocols (Fundamentals of TCP/IP networking, router and routing operation and protocols and configuration);
  • Network Services 1 (Operation and configuration of basic networking services – DHCP, NTP, NAT/PAT, etc.);
  • Operating Systems (Linux POSIX programming API, command line and bash programming);
  • Security  (Access Control Lists (ACLs); Cisco Common Classification Policy Language (C3PL))

It is assumed that the student has mastered these contents, since they will be extensively used but not introduced.

Teaching Methodologies

Theoretical classes:

  • Presentation and class brainstorming about the covered topics with emphasis on critical thinking about the relevant aspects of the current technological solutions.

Practical classes:

  • Setup, configuration, and analysis of the availability and performance levels of communication networks and information processing systems under abnormal conditions.

Learning Results

This course addresses, at a conceptual and experimental level, metrics, strategies and technologies related to the quantification and improvement of the availability and performance of communication and information processing systems.
