Availability and Performance

The Recommended Background concepts are the following (organized by course):

• Introduction to Communication Networks (TCP/IP networking stack basics; L2/L3 addressing; direct and indirect routing; 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);
• Operating Systems (Linux POSIX programming API; Linux command line and bash programming);
• Security (Access Control Lists (ACLs); Cisco Common Classification Policy Language (C3PL));

It is assumed that the student masters these contents since they will not be introduced in the present course but will be extensively used.

Theoretical classes:

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

Practical classes:

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

This course focus, at a conceptual and experimental level, on metrics, strategies and technologies designed to quantify and improve the levels of availability and performance of communication and information processing systems.
