List of network protocols (OSI model)
This article is about network protocols organized by OSI model. For network protocols organized by TCP/IP model, see Internet Protocol Suite.
This is a list of network protocols, categorized by their nearest Open Systems Interconnection (OSI) model layers. This list is not exclusive to only the OSI protocol family. Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers. The OSI model | 7 Application layer | 6 Presentation layer | 5 Session layer | 4 Transport layer | 3 Network layer | 2 Data link layer | * LLC sublayer * MAC sublayer | 1 Physical layer | * v * t * e |

...layered approach, where a communication subsystem is broken down into seven layers, each one of which performs a well-defined function. Additionally it is important to understand the purpose of the OSI model in the overall networking architecture especially as it relates to the TCP/IP (Transmission Control Protocol/Internet Protocol) Architecture, which also consists of layers each playing a particular role in the networking design. Generally speaking, the network protocol layer, which is similar to the data and network layer of the OSI model includes the protocols that allow clients and applications to send data over the network. This includes TCP/IP, NWLink (IPX/SPX), NetBEUI, Infrared Data Association (IrDA). However, the purpose of this document is to focus on the relationships between the OSI model and the TCP/IP architectures, and how they may interact together. Finally, as demonstration of this relationship a visual diagram has been provided to depicts how the TCP/IP layers correspond to the OSI model and layers. To begin with, it is important to understand the seven different layers of OSI Model and the functions they provide in the networking architecture. Below is a list of each OSI layer, their description and the function they serve in processing data over the network. • The application layer is the end-user process requests with applications and communication, all application specific. The function of an...

...CMIT 350 WAN and SOHO Skills Implementation Prepared for: University of Maryland University College CMIT 250 Prepared by: Devin Manning I. Site “Los Angeles” Challenge and Implementation The site administrator has requested that the site establishes remote IOS storage, remote management of switches, ACL list implementation, and a network time protocol for devices as described in the site specific portion of the scenario. II. Site Solutions and Technologies * The recommended course of action for the request of a remote IOS storage capability at the site would be to establish a remote access server using a HTTP/ HTTPS protocol as opposed to the SSH option mainly because of the security and control over things such as the internet connection to the routers from not only the user database, but the source addresses as well in regards to their perspectives. This particular protocol also requires the timing information to be in setup and in place which would complement the network time protocol solution that has been requested by the site. For this request, I would use the SonicWall software in order to setup up this capability along with the SonicWall UTM appliance that is provided by the company. * In order to address the remote management of the switches request, it would require a console cable and a server that has an available console port such as the Cisco Nexus 2228TP GE Fabric Extender expansion module which is one of the easier servers to use......

The VPN connection across the Internet is technically a wide area network (WAN) link between the sites but appears to the user as a private network link—hence the name "virtual private network”. The following authentication protocols are supported for logon security for VPN connections in Windows 7: * PAP Stands for Password Authentication Protocol; uses plaintext (unencrypted) passwords. * CHAP Stands for Challenge Handshake Authentication Protocol; uses one-way MD5 hashing with challenge-response authentication. * MSCHAPv2 Stands for Microsoft Challenge Handshake Authentication Protocol version 2; an extension by Microsoft of the CHAP authentication protocol that provides mutual authentication of Windows-based computers and stronger data encryption. MSCHAPv2 is an enhancement of the earlier MS-CHAP protocol that provided only one-way authentication of the client by the server. * EAP Stands for Extensible Authentication Protocol; extends PPP by adding support for additional authentication methods including using smart cards and certificates. * PEAP Stands for Protected Extensible Authentication Protocol, or Protected EAP; enhances the protection provided by EAP by using...

...DeVry University Johnnie Walker July 7, 2014 RFC'c First, I have to define the term RFC. The acronym "RFC" stands for "Request for Comment". This refers to a description of a standard for new or modified internet or networking protocols. When standards are proposed, they are made available for public comment so that they can be refined and agreed upon. The document which details the proposed standards is called a "request for comment" document, or RFC. When the standards are finalized, they keep the same "RFC" Three organizations under the Internet Society are responsible for the actual work of standards development and publication: Three organizations under the Internet Society are responsible for the actual work of standards development and publication:name. Now a Request for Comments (RFC) is a publication of the Internet Engineering Task Force (IETF) and the Internet Society, the principal technical development and standards-setting bodies for the Internet. Request for Comments documents were 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. Today, it is the official publication channel for the Internet Engineering Task Force (IETF), the Internet Architecture Board (IAB), and — to some extent — the global community of computer network researchers in general.
