What Are Pseudo-Wires?
Pseudo-wire is a mechanism used in networking and telecommunications to emulate various services using packet switched networks with technologies such as Ethernet, MPLS (Multi Protocol Labelled Switching) and IP (Internet Protocol). More ...
Routing Technologies, Bandwidth Management and Traffic Shaping
Bandwidth is the overshadowing issue for most network quality problems. The response to that problem is often to add more bandwidth. However, more bandwidth often comes at a relativel high cost. More ...
The Complete Guide to Fiber Optic Connectors
There have been over 100 different fiber optic connectors developed over the years but a select few have stood the test of time and beat out their competition. In this article we talk about the most common. More ...
Wireless or Wired Network?
Do you want the freedom of a wireless network, or do you want the security and reliability of a wired network? Both networks can provide you with great service and expandability, but each one varies in size, reliability, cost and speed. More ...
Computer Networking Devices
Computer networking devices, also known as networking hardware or network equipment are components connected to the network by network media. This article describes the function of the hub, bridge, switch, router, gateway, multilayer switch, and brouter. More ...
Technologies for the Internet of Things (IoT)
Internet of Things (IoT) refers to the effort to connect everyday objects to the Internet in order to make them smart. Many wireless technologies are used to make IoT a reality. More ...
Hubs, Switches and Routers - What's the Difference?
The terms "hub", "switch", and "router" are often used interchangeably and - in fact, the devices are quite different. Hubs are used to simply interconnect individual computers. Switches do the same more efficiently. However, routers interconnect different networks (as opposed to individual machines). More ...
Network Hubs
A hub lives at Layer 1 of the OSI model, so it does not make forwarding decisions. Instead, a hub receives bits on one port and then retransmits those bits out all other ports. Because of this a hub is sometimes called a repeater. More ...
Understanding Optical Fiber Types
Two major types of optical fibers exist for communication systems: multimode and single mode. Multimode fiber can carry many modes of light rays, while single mode fiber can only carry one mode of light ray. More ...
What is FTTP, FTTH, FTTB, and FTTD?
Some FTTx such as FTTN (fiber to the node), FTTC (fiber to the curb) depend on copper wires for final connection to the customers premises which contrasts with FTTP. FTTP can be further categorized into FTTH (fiber to the home), FTTB (fiber to the building), etc. More ...
Beginners Guide to Fiber Optic Bit Error Ratio (BER) Measurement
Bit error ratio (BER) measurement is the fundamental measurement of the quality of the fiber optic communication system. It measures the system's probability that transmitted bits will be correctly received as logic ones and zeros. More ...
System Area Network Interface Cards
Whereas the standard network may use twisted-pair cabling, the System Area Network may use separate fiber-optic cabling. System Area Network interface cards are special high speed circuits that provide communications between the servers over the System Area Network. More ...
Distance Vector vs. Link State vs. Hybrid Routing
Routers direct traffic between networks or subnetworks to transport a packet to its destination. Distance Vector routing uses the hop count as its routing metric. Link State routing use statistics like distance, link speed, and traffic to calculate the cost of different routes through the Internet. More ...
