What Is Fabric Networking?
The networking industry came up with the term 'Fabric' to describe networking technologies that allow switches to connect in a way to achieve a mesh topology. 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 ...
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 ...
Wireless Network Standards - 80211a, 80211b, 80211g, 80211n, 80216
This article describes the 80211a, 80211b, 80211g, 80211n, 80216, the current IEEE defined wireless protocol standards in use today, their bandwidth, maximum data rate, and coverage area. More ...
IPv4 to IPv6 Transition With the Dual-Stack Technique
Transition from IPv4 to IPv6 has been slow. If you can't immediately convert all your network hardware to IPv6, the dual-stack technique allows the easiest operation of IPv4 and IPv6 devices on the same network. 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 ...
Free eBook: IPv6 Addressing
All the IPv4 addresses are quickly being used up. The conversion to IPv6 is now underway. In this free eBook, Aaron Balchunas describes IPv6 and how to configure it to work along side IPv4. Learn which protocols will need to be updated to work with IPv6. Learn how to configure IPv6. 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 ...
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 ...
IEEE 802.11.x Wireless Standards
The 802.11 standard, approved in 1997, applies to wireless LANs with a 1 or 2 Mbps transmission rate in the 2.4 GHz band. Sometimes the term 802.11 is used to refer to the 802.11x family of specifications. More ...
IPv6 Address Types and Scopes
An IPv6 addresses have a size of 128 bits have three types, unicast, multicast, and anycast. Unicast addresses are for a one-to-one communication. Multicast addresses are for a one-to-many communication. Anycast addresses are for one node to nearest node of multiple nodes communication. More ...
Video - Transport Layer (Layer 4) of OSI Networking Model
In this video by Kevin Wallace you learn about the Transport Layer of the OSI networking model. More ...
OSI Transport Layer
The Transport layer (OSI layer 4) uses connection-oriented protocols to provide a reliable end-to-end connection between the source computer and the destination computer. Transmission Control Protocol (TCP) is a transport layer protocol. More ...
PoE (Power Over Ethernet)
Say you want to mount a wireless access point (AP) on the ceiling. Although no electrical outlet is available, a switch feature called Power over Ethernet (PoE) IEEE 802.3at standard offers as much as 32.4W of power over a UTP cable. More ...
Ports and Sockets
Data transmitted over the Internet carries a 32-bit IP address that identifies its destination computer and a 16-bit number that identifies a port on that computer. The combination of the IP address and the port number is called a socket. A pair of sockets, one on the sending computer and one on the receiving computer uniquely identifies a specific connection on the Internet. More ...
