IPv6 Neighbor Discovery Protocol (NDP)
Neighbor Discovery Protocol (NDP) is used by IPv6 hosts for Router Discovery, Neighbor Discovery and Duplicate Address Discovery. More ...
NTP Server Systems - The Network Time Protocol
The Network Time Protocol (NTP) is utilized by NTP Server systems to distribute accurate time information to network time clients. The NTP protocol is widely used throughout the Internet to provide synchronization of computers and processes. This article discusses how NTP server systems utilize the Network Time Protocol to provide networks with an accurate reference of time. 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 ...
Video - Introducing the OSI Model
This video by Kevin Wallace introduces the OSI networking model. More ...
Free eBook: Introduction to 802.11 Wireless
The growth of wireless mobile devices is incredible. If you're an IT professional you'll need to understand wireless technology. This free ebook by Aaron Balchunas explains everything from radio frequency to wireless authentication protocols. More ...
Neighbor Discovery Protocol (NDP)
Neighbor Discovery Protocol is part of the new version of the Internet Protocol (IPv6). Its function is to resolve IPv6 addresses into valid MAC addresses. All addresses discovered by NDR are stored in a buffer known as the neighbor cache. More ...
SYN-ACK Handshake to Establish a TCP Connection
TCP uses a SYN-ACK handshake to establish a connection. Three messages are required to establish a TCP connection between two hosts. More ...
IEEE 802 Standards Specify the Basics of Physical and Logical Networking
The (IEEE) Institute of Electrical and Electronics Engineers is an organization that defines standards for networking. The 802 Standards Specify the Basics of physical and logical networking. More ...
DSL (Digital Subscriber Line)
DSL (Digital Subscriber Line) is a technology used to transmit digital data over telephone lines. DSL service can be transmitted simultaneously with voice band telephone service on the same line because DSL uses a much higher frequency that rides on top of the low 3400 Hz voiceband. More ...
IPv6 Address Format
IPv4 is running out of addresses. IPv6 was designed to solve this problem therefore it is important
to understand the format of an IPv6 address. 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 ...
Shortest Path Bridging (SPB) Protocol
Shortest Path Bridging (SPB) protocol is a computer networking technology intended to simplify the creation and configuration of networks, while enabling multipath routing. It is the replacement for the older spanning tree protocols. More ...
Kerberos Authentication Protocol
Kerberos is an authentication protocol which allows computers communicating over a non-secure network to prove their identity to one another. Windows 2000 and later use Kerberos as their default authentication method. More ...
The OSI Reference Model
No real world network operating systems conform exactly to the OSI model, but it is useful as a reference when describing existing systems. It is difficult to study network devices such as routers, switches, and gateways without using the model. More ...
IPv6 Multicast Addresses
An IPv6 multicast address defines a group of devices known as a multicast group. Unlike IPv4, there is no broadcast address in IPv6. Instead, IPv6 uses multicast. A packet sent to a multicast group always has a unicast source address. More ...
