The presentation offers a detailed examination of network standard protocols, elucidating critical concepts such as the role of key standardization organizations like IEEE and ANSI, the functionalities of various application layer protocols such as SMTP, FTP, and DNS, the distinctions between TCP and UDP connections, the significance of port numbers in directing data traffic, the structure of TCP and UDP headers, the intricacies of SYN-ACK handshake mechanism for initiating TCP connections, the importance of sequence and acknowledgment numbers for reliable data transmission, the implementation of window sliding mechanism for flow control, and the graceful termination of TCP connections through a four-way handshake process.

What is the standards in
the context of networking?
Standards are documented agreements containing technical
specifications or other precise criteria that stipulate how a
particular product or service should be designed or performed.

PAGE 1
Institute of Electrical and Electronics Engineers
(IEEE)
Is an international society composed of engineering professionals. It aims to
promote development and education in the electrical engineering and
computer science fields.
American National Standards Institute (ANSI)
Is an organization composed of more than one thousand representatives from
industry and government who together to determine standards for electronics,
industry and other fields such as chemical and nuclear engineering, health
and safety, and construction.
Electronic Industries Alliance (EIA)
Is a trade organization composed of representatives from electronics
manufacturing firms across the United States. This organization writes ANSI
standards and legislation favorable to the growth of computer and electronic
industries.
Telecommunications Industry Association (TIA) Focuses on standards for information technology, wireless,
satellite, fiber optics, and telephone equipment.

Internet Engineering Task Force (IETF)
Is an organization that is responsible for the overall development of the
Internet and the standardization of internetworking technologies. In short, the
IETF sets standards for how systems communicate over the Internet.
- Internet Society (ISOC)
- Internet Engineering Steering Group (IESG)
- Internet Architecture Board (IAB)
- Internet Assigned Numbers Authority (IANA)
Organization for Standardization (ISO)
The International Organization for Standardization (ISO) is an
international standards organization responsible for a wide range of
standards, including many that are
relevant to networking.

Application Layer
Protocols (Huawei, 2020)
The application layer provides interfaces for application software
so that applications can use network services. The
application layer protocol designates transport layer protocols
and ports.

Simple Mail
Transfer Protocol
(SMTP)
Post Office
Protocol, version 3
(POP3)
Trivial File Transfer
Protocol (TFTP)
File Transfer
Protocol (FTP)

(NFS)
Domain Name System
(DNS)
Simple Network Management
Protocol (SNMP)
Terminal Emulation
Protocol Network (Telnet)
Hypertext Transfer
Protocol (HTTP)
Remote login application
(rlogin)

Protocol over Secure Socket
Layer)
- Managed devices
- Agent
- NMS

SYN-ACK Handshake
(Huawei, 2020)

10. Three-way
handshake
a method, in which the sender
and the receiver inform their
respective operating systems
that a connection will be
initiated before the actual data
communication begins.
• SYN - Synchronize
• ACK - Acknowledge
• FIN - Finish

11. Sequence Number
and Acknowledgment
Number
fields to implement reliable and
ordered data transmission.

12. Window Sliding
Mechanism
Requires the sender to receive
an acknowledgment from the
receiver after transmitting a
certain amount of data.

13. TCP Shutdown
(FourWay
Handshake)
is engaged when the data
transmission is complete in
order to disconnect the TCP
connection and release
system resources.
