What is rfc1122?
What is rfc1122?
In computer networking, the link layer is the lowest layer in the Internet protocol suite, the networking architecture of the Internet. The link layer is the group of methods and communications protocols confined to the link that a host is physically connected to. The link layer is described in RFC 1122 and RFC 1123.
What RFC 1123?
93 Internet Engineering Task Force [Page 4] RFC1123 INTRODUCTION October 1989 1. INTRODUCTION This document is one of a pair that defines and discusses the requirements for host system implementations of the Internet protocol suite. This RFC covers the applications layer and support protocols.
What is an RFC protocol?
RFC (stands for Request For Comments) is a document that describes the standards, protocols, and technologies of the Internet and TCP/IP. Any member of the Internet Society (ISOC) can submit an RFC for consideration, although submission is usually done through the Internet Engineering Task Force (IETF).
What is IETF model?
This is a protocol-independent YANG data model with topology information. It is separate from, and not linked with, data models that are used to configure routing protocols or routing information. This includes, for example, the “ietf-routing” YANG module [RFC8022].
What kind of protocol is TCP?
Transmission Control Protocol (TCP) – a connection-oriented communications protocol that facilitates the exchange of messages between computing devices in a network. It is the most common protocol in networks that use the Internet Protocol (IP); together they are sometimes referred to as TCP/IP.
Which RFC defines the appropriate Behaviour for the TCP protocol?
RFC 5382: NAT Behavioral Requirements for TCP.
What DNS 1123?
DNS Subdomain Names Most resource types require a name that can be used as a DNS subdomain name as defined in RFC 1123. This means the name must: contain no more than 253 characters. start with an alphanumeric character. end with an alphanumeric character.
What is RFC and its purpose?
In the computer network engineering and design realm, a Request for Comments (RFC) is a memorandum published by the Internet Engineering Task Force (IETF) describing methods, behaviors, research, or innovations applicable to the working of the Internet, along with Internet-connected systems.
What is the purpose of RFC?
The RFC system was invented by Steve Crocker in 1969 to help record unofficial notes on the development of ARPANET. RFCs have since become official documents of Internet specifications, communications protocols, procedures, and events.
What is NETCONF used for?
NETCONF is a protocol defined by the IETF to “install, manipulate, and delete the configuration of network devices”. NETCONF operations are realized on top of a Remote Procedure Call (RPC) layer using an XML encoding and provide a basic set of operations to edit and query configuration on a network device.
What is NETCONF YANG?
NETCONF is the standard for installing, manipulating and deleting configuration of network devices while YANG is used to model both configuration and state data of network elements. NETCONF is defined for transaction-safe configuration of devices.
What is TCP in simple words?
What is the purpose of the RFC 1123?
Summary This is one RFC of a pair that defines and discusses the requirements for Internet host software. This RFC covers the communications protocol layers: link layer, IP layer, and transport layer; its companion RFC-1123 covers the application and support protocols.
What does RTO stand for in RFC 1122?
The duration of this timer is referred to as RTO (retransmission timeout). RFC 1122 [ Bra89] specifies that the RTO should be calculated as outlined in [ Jac88 ]. This document codifies the algorithm for setting the RTO.
What’s the status of RFC 4379 and 6424?
This document obsoletes RFCs 4379, 6424, 6829, and 7537, and updates RFC 1122 . Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community.
When was the first version of rfc1122 published?
RFC1122 INTRODUCTION October 1989 the present document and its companion [INTRO:1] define the rules for the current realization of the Internet architecture. Internet hosts span a wide range of size, speed, and function. They range in size from small microprocessors through workstations to mainframes and supercomputers.
