Video - Network Layer (Layer 3) of OSI Networking Model
In this video by Kevin Wallace you learn about the Network Layer of the OSI networking model. More ...
VTP (VLAN Trunking Protocol)
A VLAN (Virtual LAN) allows a network administrator to partition a LAN to conform to the business functions of the organization without physically modifying the network. VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol that allows an administrator to configure VLANs on a single VTP server, easing the administration of a network. More ...
Remote Control Protocols
Remote control protocols like Remote Desktop Protocol (RDP), Secure Shell (SSH), and Citrix Independent Computing Architecture (ICA), allow a system to access another system and transfer the user interface, keystrokes, and mouse movements between syatems as if you were actually sitting at the other syatem. More ...
Basic TCP/IP Networking
In this article, I'm going to describe how a network works. I am NOT not going to load you down with details. Instead, I'm just going to describe what happens when you start your client computer. How it gets access to the network. More ...
Routing Information Protocol (RIP), Open Shortest Path First (OSPF), and Routing Convergence
A routing protocol advertises route information between routers. Dynamic routing protocols are available that allow a router's routing table to be updated as network conditions change. More ...
Network Gateways
When networks with different protocols, such as Ethernet and Token Ring need to be connected together, this requires reconstruction of the data packets. To do this, information from above the network layer is required. A gateway is a device that can function at all seven layers of the OSI model. More ...
X.25 and Frame Relay Overview
Frame Relay originated as an extension of integrated services digital network (ISDN). Its designers aimed to enable a packet-switched network to transport over circuit-switched technology. The technology has become a stand-alone and cost-effective means of creating a WAN. More ...
Internet Protocol versions IPv4, IPv5 and IPv6
Internet Protocol is the part of the TCP/IP protocol that is responsible for addressing packets. IPv4 uses a 32-bit address IPv6 uses a 128-bit address. This article describes how IPv4 are converted to IPv6 addresses. More ...
Video Streaming Protocols
Video surveillance systems currently are undergoing a transition where more and more traditional analog solutions are being replaced by digital solutions. Here, some of the network protocols used in video streaming are described. More ...
The OSI Session Layer
The Session layer, layer seven of the OSI model, establishes, synchronizes, maintains and terminates sessions between computers on a network. It establishes a connection ID and authenticates security. More ...
The OSI Network Layer
The Network layer (OSI layer 3) uses routable protocols to deliver data packets to networks connected through routers. Routing is the process of moving data packets from one network or network segment to another. More ...
IPv6 Neighbor Discovery Protocol (NDP)
Neighbor Discovery Protocol (NDP) is used by IPv6 hosts for Router Discovery, Neighbor Discovery and Duplicate Address Discovery. More ...
IP version 6 (IPv6) Advantages and Implementation
The Internet has, to all intents and purposes, run out of public IP version 4 addresses. The solution to this issue is new IP version 6. This would require a parallel IPv6 based Internet to be running until all IPv4 connections have been converted. More ...
RADIUS Protocol
RADIUS (Remote Authentication Dial-In User Service) is an application layer protocol that provides centralized Authorization, Authentication, and Accounting management for users who connect and use a network service. More ...
How to Set Up FTP (File Transfer Protocol)
FTP (File Transfer Protocol) is used to transfer computer files between a client and server on a network. This article explains how to set up FTP on IIS and that FTP is not a secure protocol and some secure file transfer alternatives. More ...
