RFC 8200 - Internet Protocol v6 (IPv6)

RFC 8200 is a technical document that specifies the details of the Internet Protocol Version 6 (IPv6), which is designed to be the successor to the older IPv4. It describes the IPv6 header format, its optional extension headers, and how packets are fragmented and reassembled. Additionally, it provides guidance on security considerations, traffic management, and compatibility with upper-layer protocols. RFC 8200 was published in July 2017 and updates the original IPv6 specification from RFC 2460.

RFC 791 - Internet Protocol 4 (IP)

RFC 791 is a document that details the specifications of the Internet Protocol (IP). It was originally written in 1981 and describes how IP functions to deliver packets of data called datagrams from one computer to another across a network of interconnected systems. It also defines key aspects of IP, such as addressing, which provides a method for identifying and locating computers, and fragmentation, which allows large datagrams to be divided into smaller pieces for transmission over networks with limited capacity. The document explains how gateways forward datagrams between networks and how IP interacts with other protocols, such as TCP and UDP. RFC 791 provides a comprehensive guide to the technical details of IP and its role in the internet’s foundational architecture.

RFC 9293 - Transmission Control Protocol (TCP)

RFC 9293 is a technical document that defines the Transmission Control Protocol (TCP), a fundamental protocol for reliable data communication on the internet. The document provides a comprehensive overview of TCP’s functionality, including connection establishment and termination, data transmission and retransmission, and various mechanisms for ensuring reliable and efficient data delivery. It also details TCP’s interaction with lower-level protocols like IP and ICMP. RFC 9293 serves as the authoritative specification for TCP implementation and is essential for developers and network engineers working with the internet. Link to RFC

RFC 9000 - QUIC: A UDP-Based Multiplexed and Secure Transport

RFC 9000 outlines the QUIC (Quick UDP Internet Connections) transport protocol, a secure, connection-oriented protocol that builds on UDP for reliable and fast data exchange. It defines QUIC version 1, emphasizing its connection-oriented nature, handshake process, and integrated TLS 1.3 for security. QUIC utilizes streams for data transfer, incorporates flow control to prevent resource exhaustion, and implements congestion control to avoid network overload. It also supports connection migration, enabling connections to gracefully transition to new network paths. The document further explores packet and frame formats, error codes, and security considerations, analyzing potential attacks and outlining mitigation strategies. Link to RFC

RFC 4271 - Border Gateway Protocol 4 (BGP 4)

RFC 4271 is a standard that defines the Border Gateway Protocol version 4 (BGP-4), an inter-Autonomous System (AS) routing protocol used to exchange network reachability information between routers. BGP-4 allows systems to advertise a set of destinations as an IP prefix, eliminating the need for the “class” concept. This document outlines how BGP-4 functions, including message formats, path attributes, error handling, state machines, and route selection procedures. It also explores how to control routing traffic overhead and enhance routing information efficiency through aggregation. Additionally, the document delves into security considerations, discusses the use of TCP MD5 authentication, and provides guidance on implementation recommendations and IANA considerations.
