This course is intended to provide specialized knowledge on the field of computer networks. The course e based on two complementary vectors, the solid theoretical foundations on algorithms and protocols that support the operation of (modern) data networks, across multiple abstraction levels, with some emphasis on routing protocols; and a hands-on practical component focused on the configuration (and management) of data networks, with emphasis on the design and deployment of data networks through the configuration of specialized network equipment (switches and routers). This course sonsolidates knowledge that was transmitted on introdutory courses on computer networks and expand this knowledge base significantly with both theoretical and practical foundations.

This curricular unit (UC) aims at consolidating and developing the knowledge of students in the field of computer networks and data networks, through the exposition and study of several principles, algorithmsm and protocols that support the operation of these networks.

The UC has not only a strong theoretical component associated with the design of key protocols in todays Internet, but also a strong practical component related with the configuration and operation of data networks.

Know:

• Fundamental concepts related with the operation and architecture of modern data networks.
• Understand the operation and design of routing protocols.
• Concepts related with the operation of modern data networks (not only the Internet but also Data Centers)

Know how to do:

• Configure and administration of data networks at several abstraciton levels.
• Use in an correct way routing protocols (RIP, OSPF, BGP)
• Teste and experimental validation of the correct operation of a data network.
