Frame Relay WAN Protocol
Frame Relay is WAN protocol and operates for LAN internetworking at data link layers. It is a packet-switched technology designed for swift digital transmission of data. Data integrity is not guaranteed and packets are discarded during network congestion. 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 ...
LAN Network Protocols - Ethernet, STP, Fiber
Spanning Tree is an algorithm that runs on Layer 2 campus switches for preventing Layer 2 loops and broadcast storms on a network with at least 2 switches or bridges. The algorithm determines what ports at each switch or bridge must be blocked to create a loop free topology. More ...
What Are Fiber Optic Circulators?
An optical circulator is an nonreciprocal passive device that directs light sequentially from port to port in only one direction. The operation of a circulator is similar to that of an isolator except its constructions is more complex. More ...
MPO Connector, MTP Connector, What's the Difference?
MPO stands for Multi-fibre Push On and is a fiber optic connector type. MTP is a registered trademark of US Conec. The MTP design complies with the MPO standard. More ...
How In-Row Cooling Increases Data Center Efficiency
Increased data center densities enable operators to meet the demands of cloud and hyper-scale environments. As more power is consumed per rack, however, heat becomes a big problem. Most modern data centers have adopted some sort of aisle-containment solution to minimize the mixing of hot and cold air. More ...
A Guide to Broadband Internet Connections
By this point, most of America already has a Broadband Connection to the Internet. But for those that have not yet taken the plunge, a world of benefits awaits you. Broadband can get you surfing up to 50 times faster than a typical 56K modem. More ...
What is an Ethernet Switch?
An Ethernet switch is a networking device that is able to interrogate the data within the Ethernet Frames to provide forwarding and filtering and loop avoidance. More ...
Voice Over IP Protocols and Components
Voice over IP (VoIP) is a technology that digitizes speech into packets and transmits those packets across a data network. This allows voice, data, and video to share the same medium. More ...
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 ...
Data Center Management Best Practices
The use of an integrated best practices approach to data center management involves efficient management of resources while still minimizing the costs of all the different interrelated competing factors that require attention. 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 ...
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 ...
