Students are expected to have completed
Access Networks and Shared Media Communications Networks and Services Systems Architecture I Systems Programming
Competences and skills that will be acquired and learning results. Further information on this link
The goal of this subject is to study the end-to-end protocols that support Internet applications, i.e., the advanced aspects of transport layer protocols, and the main application layer protocols: DNS, e-mail, file transfer, remote terminal, web, etc. The student will acquire the following competences: - Understanding the advanced functions of the transport layer protocols (e.g., the flow control and congestion control mechanisms in TCP). - Knowing the basic principles of cryptography and security, symmetric and public key algorithms, digital signature, message digest, public key infrastructure, security in transport layer (TLS) and application layer. - Knowing the architecture, message format, and how the different application layer protocols studied in the subject work: name service, file transfer, remote terminal, e-mail. Web, and time protocol. - Being able to program applications using sockets. - Solving practical cases of use of the different application layer protocols in different computer networks. The general skills are: - (PO a) ability to apply knowledge telecommunication technologies and engineering, specifically the ones related with transport and application layer protocols. - (PO e) ability to identify, formulate, and solve engineering problems related with communication protocols at the network and application layers. - (PO i) recognize the need for, and an ability to engage in life-long learning. Students will have to obtain information for self-study and for the practice from Internet standards (RFCs).
Description of contents: programme
The content of the program will be the following: 1. Advanced aspects of transport protocols - Introduction to TCP - Establishing and finishing connections. State diagram. Massive and interactive traffic. TCP algorithms: Nagle, slow start, congestion control, fast recovery/fast retransmit, etc. - TCP timers: retransmission, persistence, keep-alive. Calculus and practical considerations. - New variants of TCP. - Programming applications using sockets. 2. Security in application and transport layer protocols. - Basic principles: Symmetric Key Cryptography, Public Key Encryption, Message Integrity and Digital Signatures - Securing TCP Connections (TLS) and application. 3. Domain name servers: DNS 4. Synchronization protocols: NTP 5. Classic protocols: - Remote login: telnet y rlogin - File transfer: FTP y TFTP 6. E-mail: - Formats: RFC 822, MIME - Sending protocols: SMTP - Final delivery protocols: POP e IMAP 7. Web: HTTP. - HTTP/1.0. - HTTP/1.1. - Content Distribution Networks - HTTP/2, HTTP/3, QUIC, CoAP
Learning activities and methodology
- Theoretical lectures. The teacher will present the main concepts. Participation of the students, interactions, and discussions about the presented problems will be promoted (PO a, i). - Practical exercises. Sessions in which the teacher will raise some problems that will allow the students to propose and analyze some solutions (PO e). - Practices in lab. Sessions in which the student will have to solve some simple problems that illustrate the behavior of the different protocols studied in the subject, and a big practice consisting in the implementation of a protocol (PO i).
