Study Notes
User Datagram Protocol (UDP) Characteristics
- UDP provides a connectionless service that allows for fast transmission of data without establishing a connection.
- Datagrams in UDP are analogous to letters in the postal service, as they are sent independently without needing a direct connection and may arrive out of order.
- A port number representation in UDP uses 16 bits.
Port Numbers and Services
- Port numbers range from 0 to 1023 are reserved for well-known services such as HTTP (80) and FTP (21).
- The Source Port in a TCP header identifies the port from which the TCP segment originates.
Data Delivery Methods
- TCP ensures data delivery to specific applications through the use of port numbers that link data to applications like web browsers or email clients.
- The protocol designed for retrieving email from servers is the Post Office Protocol (POP).
Standards Organizations
- The Institute of Electrical and Electronics Engineers (IEEE) aims to advance technology and foster innovation through global standards.
- The protocol for reliable electronic mail transfer on the Internet is Simple Mail Transfer Protocol (SMTP).
- The protocol that allows sharing programs and data over a TCP/IP network is Network File System (NFS).
Standardization Entities
- The American National Standards Institute (ANSI) oversees standards such as the American Standard for Code for Information Interchange (ASCII).
- File Transfer Protocol (FTP) can mount drives on remote hosts, treating them as local drives.
- The Electronic Industries Alliance (EIA) plays a critical role in standardization across the electronics industry.
IEEE Contributions
- The IEEE 802 project significantly contributed to the standardization of Ethernet technology.
- TFTP stands for Trivial File Transfer Protocol, a simple protocol for transferring files.
Naming and Addressing Protocols
- The Domain Name System (DNS) translates human-readable domain names into IP addresses.
- The IEEE primarily focuses on standardizing networking and telecommunications technologies.
- The Internet Research Task Force (IRTF) serves as the technology advisory group to the Internet Society.
Oversight and Management
- The Internet Engineering Task Force (IETF) oversees activities related to Internet standards, while the Internet Corporation for Assigned Names and Numbers (ICANN) manages Internet naming and addressing.
- The International Organization for Standardization (ISO) is key in global networking standards.
- The process for introducing or updating Internet standards is managed by the IETF.
TCP Header Fields
- The Acknowledgment Number in a TCP header indicates the next expected byte by the receiver.
- The Window field in TCP headers controls the flow of data, indicating how much data can be sent before receiving acknowledgment.
- The UDP Source Port field is also represented by 16 bits.
- The Sequence Number in a TCP header defines the order of data segments for reassembly.
- The Length field in UDP headers provides the total length of the UDP packet.
- The Reserved field in TCP headers is set aside for future use and is not currently utilized.
