Computer Networks Design and Management
Study: Master in Computer Engineering (228)

Coordinating teacher: GARCIA RUBIO, CARLOS

Department assigned to the subject: Telematic Engineering Department

Type: Compulsory
ECTS Credits: 6.0 ECTS


Requirements (Subjects that are assumed to be known)
A content subject similar to the subject "Computer Networks", of the Bachelor in Informatics Engineering of the UC3M.
The objective of this subject is to study advanced aspects of the protocols that support the Internet, in particular the advanced aspects of the transport layer, security and the main application-layer protocols of the Internet: DNS, email, file transfer , remote terminal, web and others. After taking the course, the student must: - Understand the advanced functions of transport protocols (for example, TCP congestion and flow control mechanisms). - Know the basic principles of cryptography and encryption, symmetric and public key algorithms, digital signature, message summary, public key infrastructure, security in transport level communications (TLS) and application. - Know the messages and basic formats, operation, and architecture of the different application-level protocols dealt with by the subject: name service, remote terminal, file transfer, email, web.
