Wireless Network Vlans - How to Implement Wireless Vlans
Wireless access points operate as bridges with no routing defined anywhere on the wireless network segment. VLANs are defined on the wired switches and mapped with specific SSIDs at each access point. The wireless client associates with a specific SSID which in turn will map client with membership in a specific VLAN. More ...
Understanding Wireless LAN Networking
Wireless networking allows computers and peripherals to communicate using radio frequency (RF) transmissions rather than over conventional network cabling. Using wireless Ethernet adaptors, any device capable of being used on a regular computer network can be accessed over a wireless connection. More ...
The IEEE 802.3 Ethernet Standards
The Institute of Electrical and Electronics Engineers (IEEE). The IEEE sets up committees to define industry standards. The IEEE 802 committee sets the standards for networking. The IEEE subcommittee 802.3 sets the standard for Ethernet. More ...
Understanding the Basics of All-Optical Switching
All-optical switching is a process by which light in the form of digital communication signals is routed from one transmission channel to another without intermediate conversion to another format. More ...
Introduction to ATM (Asynchronous Transfer Mode) Networks
ATM (Asynchronous Transfer Mode) is a network technology to provide broadband services for the transmission of voice, video, and data at speeds up to 1Gbps. More ...
Network Storage Server Options
Although the need for storage available over a shared network is evident, it is not always clear which solution is right for your organization. There are a variety of options available, direct-attached storage (DAS), network-attached storage (NAS) and storage area networks (SAN). More ...
Bluetooth Basics
Bluetooth wireless technology is a specification for a wireless connection that provides links between mobile computers, mobile phones, other portable handheld devices, and connectivity to the Internet. More ...
How to Set up a Private Network
A private network is one which does not connect directly to the internet, but does allow you to connect to other computers that are on the same physical network. More ...
Transparent Bridging and MAC Address Filtering
A bridge uses a database to send frames across network segments. The database is a list of nodes MAC addresses and their locations on the network. To send a frame between two segments a bridge reads a frame's destination MAC address and decides to either forward or filter. More ...
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 ...
The Difference Between a Hub and a Router
For someone who needs a quick clarification on the matter, a hub combines all linked computers or workstations into a network, while router links two separate and distinct networks to each other. More ...
What Are Fiber Optic Attenuators?
A fiber optic attenuator, also called an optical attenuator, simulates the loss the would be caused by a long length of fiber. For a fiber optic receiver, too much light can overload it and degrade the bit error ratio. More ...
Network Broadcast Storms
When a switch receives a broadcast frame the switch floods the frame out all switch ports other than the port on which the frame was received. Because a layer 2 frame does not have a TTL (Time to live) field, a broadcast frame endlessly circulates through the Layer 2 topology. More ...
