Rymote is a Cisco remote network optimisation service with expertly qualified Cisco network engineers on hand. Cisco Systems, Inc. is an American multinational corporation that designs, manufactures, and sells networking equipment worldwide. Founded in 1984 by husband and wife team Leonard Bosack and Sandra Lerner Cisco went from strength to strength and thrived during the Dot-Com Boom. With over 12,200 patents issued, and more than 700 patents filed for each year, they’re at the cutting edge of networking, offering businesses and individuals best-in-class solutions.
Interconnecting Cisco Network Devices refers to a set of IT exams issued by Cisco Systems.
An Internet telephony service provider offers digital telecommunications services based on Voice over Internet Protocol (VOIP) that are provisioned via the Internet. ITSPs are commonly known as VoIP providers.
Short for Private Automated Branch Exchange, this telephone network is commonly used by call centres and other organizations. PABX is an automatic telephone switching system within an enterprise. These systems were originally called PBX and required a live operator – today, most private branch exchanges do not have live operators and are automatic, hence PABX.
Software-defined networking (SDN) is an approach to computer networking which evolved from work done at UC Berkeley and Stanford University around 2008. SDN allows network administrators to manage network services through abstraction of lower level functionality. This is done by decoupling the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forward traffic to the selected destination (the data plane). The goal of SDN is to allow network engineers and administrators to respond quickly to changing business requirements, giving more control to administrators.
The Session Initiation Protocol (SIP) is a very flexible signalling communications protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP) networks. SIP can be used for simple telephone calls, video and audio multicast meetings, instant messaging conferences and more.
Shortest Path Bridging (SPB), specified in the 802.1aq standard is a layer 2 loop avoidance method designed to replace the older Spanning Tree Protocol (STP). STP permitted only one path back to the root bridge in a network, therefore blocking any redundant paths. SPB uses features of ISIS (Intermediate System-Intermediate System) to calculate the network topology and provide the most efficient path for traffic to navigate the network.
TRILL (“Transparent Interconnection of Lots of Links” is an IETF standard which combines the advantages of bridges and routers using link state routing features to address loops in a layer 2 network.
The UC500 is an umbrella term for a series of devices manufactured by Cisco Systems. It is intended as an all in one solution for most businesses communications requirements and embraces a technology set known as unified Communications. As of January 2014, it has become end of sale (EoS).
VoIP stands for Voice over Internet Protocol. It is sometimes referred to as Voice over Networks (VoN), Voice over Broadband (VoB) and simple Internet Telephony. Essentially, VoIP is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over the Internet. VoIP allows users to make free, or very inexpensive, calls over the internet. A common VoIP service is Skype.
