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 ...
Session Border Controllers - More Than Just a Voice Firewall
The migration from Time-Division Multiplexing to the more flexible IP based SIP networks brought an unexpected security challenge. Session Border Controllers focused primarily on SIP and H.323 session security. 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 ...
Integration of IPv6 with IPv4
Almost all networks use IPv4. The question is how to move them over to IPv6 while allowing them to keep the networks they currently have operating. There are three methods. More ...
IPv6 Anycast Addresses
An IPv6 anycast address can be assigned to more than one interface. In other words, multiple devices can have the same anycast address. A packet sent to an anycast address is routed to the nearest interface having that address, according to the routers routing table. 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 ...
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 ...
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 ...
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 ...
Link Aggregation
If all ports on a switch are operating at the same speed, the ports most likely to experience congestion are ports connecting to another switch or router. To help alleviate congested links between switches, you can logically combine multiple physical connections into a single logical connection. More ...
Wireless Standards - 802.11a 802.11b 802.11g 802.11n 802.11i Explained
The IEEE 802.11 family of standards which provides for Wireless Ethernet or (Wi-Fi) has evolved over the years. This article explains the differences between 802.11a 802.11b 802.11g 802.11n and 802.11i. 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 ...
Networking Protocols, Ports, Standards, and Organizations What Does it All Mean?
A protocol is a set of rules that devices agree to. A port is specific electronic connection, or software interface a protocol uses. A standard is a specification that the characteristics of the protocol's signal and the design of the interface. Networking standards are developed by networking standards organizations. More ...
WAN Network Protocols - DSL, SONET, HDLC, DWDM, DLSW+
This article discusses some of the most implemented Wide Area Networking (WAN) protocols in enterprise networking environments today including HDLC, DSL, SONET, DWDM, and DLSW+. HDLC is a Cisco proprietary protocol for designed for sending data across serial links. 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 ...
