shortest path bridging
Shortest path bridging, or 802.1aq, is the IEEE’s specification for enabling multi-pathing in the data center. Shortest path bridging is similar conceptually to its IETF counterpart, Transparent Interconnection of Lots of Links (TRILL). Continue Reading
Transparent Interconnection of Lots of Links (TRILL)
Transparent Interconnection of Lots of Links (TRILL) is the Internet Engineering Task Force’s specification for enabling multi-pathing in the data center. The protocol is intended to replace the spanning tree protocol. Continue Reading
mean opinion score (MOS)
In voice communications, particularly Internet telephony, the mean opinion score (MOS) provides a numerical measure of the quality of human speech at the destination end of the circuit. Continue Reading

Virtual branch office in a box (vBOB) devices may replace hardware
As you introduce your enterprise WAN to virtualization, a virtual branch office in a box (vBOB) may take shape in remote offices. Learn in this tip how BOBs are being reinvented. Continue Reading
Quiz: Using 10 Gigabit Ethernet in your data center
10 Gigabit Ethernet (10 GbE) networks can reduce cost and introduce flexibility in the data center while taking on the processing load and preventing latency throughout the network. Network data center managers need to understand how 10 GbE enables ... Continue Reading

loose coupling
Loose coupling is a method of interconnecting the components in a system or network so that those components, also called elements, depend on each other to the least extent practicable... (Continued)Continue Reading
Evolved Packet Core (EPC)
Evolved Packet Core (EPC) is a flat architecture that provides a converged voice and data networking framework to connect users on a Long-Term Evolutio (LTE) network.Continue Reading
Layer 3 VPN architectures
This guide serves as an introduction to Layer 3 VPN architectures. As you consider different virtual private network types for your enterprise WAN, such as MPLS, IPsec, SSL and remote, be mindful of the traffic you want to transmit (data, voice, etc...Continue Reading

patch antenna
A patch antenna is a wafer-like directional antenna suitable for covering single-floor small offices, small stores and other indoor locations where access points cannot be placed centrally.Continue Reading
AARP (AppleTalk Address Resolution Protocol)
AARP (AppleTalk Address Resolution Protocol) is a way to map between the physical hardware addresses of computers, such as those known to an Ethernet or token ring local area network, and their temporarily assigned AppleTalk network addresses.Continue Reading
AAUI (Apple attachment unit interface)
An AAUI (Apple attachment unit interface) is the 14- or 15-pin port or connection interface on earlier models of Macintosh computers that allowed it to be connected by a short interface cable (or "transceiver") to an Ethernet cable.Continue Reading
average bouncing busy hour (ABBH)
In designing and assessing telephone networks, one approach is to measure the average bouncing busy hour (ABBH) traffic in various network trunks or trunk groups of the network.Continue Reading
modem lights (AA)
This page provides a description of the abbreviations and meanings of each of the lights that describe the "handshaking" between a computer modem and the UART chip in a computer.Continue Reading
