95th Percentile
Samples of your actual bandwidth usage are taken every five minutes from your VLAN port on the switch or T1 Channel, utilizing MRTG Bandwidth Reporting. The program then averages the totals and posts the result as a five-minute usage point on your report. Over the month, we will continue to plot the five-minute averages, which total about 8,640 points plotted on the graph.

We then take the top five percent of your usage (432 points, or 36 hours) and throw it out!

Your usage is determined based upon the highest remaining usage plotted. This method of billing provides you with a number of advantages. Any usage bursts that are untypical of your bandwidth requirements are not charged to you, and this equates to receiving approximately your highest 36 hours of bandwidth usage each month for free.

 

A

Air Conditioning (AC)
Controlling the temperature, relative humidity, air cleanliness and air motion in a space to meet the requirements of the equipment.

Alternating Current (AC)
An electrical current where the polarity of the current alternated between plus and minus 60 times a second, as opposed to direct current (DC) where the polarity of the current stays constant.

Automatic Transfer Switch (ATS)
A high availability switch which provides redundant power to connected equipment. If the primary AC power becomes unavailable due to any reason, the ATS will automatically begin sourcing power from a secondary AC line. The transfer time from one line to another is seamless to the connected equipment.

Also known as a Redundant Switch.

 

B

Backbone
The part of a network to which other networks connect. Allows data and voice to travel from one network to another. Typically includes the entire network infrastructure required to provide connectivity between all major points.

In telephone networks includes tandem switches and the transmission facilities used to interconnect them.

In a router-based data network includes the routers and the private lines or virtual circuits used to interconnect them.

Bandwidth
How much data can flow on a given transmission path within a given amount of time. Historically, bandwidth referred to the width of the range of frequencies on which electronic signals are carried on a given transmission medium. We are able to provide bandwidth solutions from simple e-mail messages to larger video content.

Bits, Bytes and more
b Bit A single binary digit.

B Byte The amount of storage generally used to store one character of information (usually 8 bits).

Kb Kilobits Thousands of bits (Kb/s= Kilobits per second)

KB Kilobytes Thousands of bytes

Mb Megabits Millions of bytes

MB Megabytes Millions of bytes

Gb Gigabits Thousands of Megabits

GB Gigabytes Thousands of Megabytes (GB/month= Gigabytes per month)

To convert from Kb per second to GB per month
GB/month = Kb/s � 3.1833

Convert from GB per month to kb per second
Kb/s = GB/month x 3.1833

 

Border Gateway Protocol (BGP)
The core routing protocol of the Internet. It works by maintaining a table of IP networks or 'prefixes' which designate network reachability between autonomous systems (AS).

Browser
An application that retrieves WWW documents specified by URLs from an HTTP server, and displays the retrieved documents according to the Hypertext Markup Language (HTML).

 

C

Carrier-Neutral
NextLevel Internet has an open policy regarding interconnection among its clients. This policy allows clients to multi-home, peer directly with other providers, or connect to any other NextLevel Internet client.

CCIE™ - Cisco Certified Internetworking Expert

CCNA™ - Cisco Certified Network Associate
One of the base certifications provided by Cisco Systems, Inc.

CCNP™ - Cisco Certified Network Professional
An advanced certification provided by Cisco Systems, Inc.

Circuit Switch
A method widely employed by telco’s to allow for a temporary dedicated path of constant bandwidth between two endpoints over a wide area.

Circuit Switched Networks
A public network dedicated to data transport which uses circuit switching techniques. Distinguished from PSTN and ISDN in that CSPDN is strictly a data network.

Circuit Switching Technology
A method widely employed by telco’s to allow for a temporary dedicated path of constant bandwidth between two end points over a wide area. Users normally pay for a circuit-switched connection on a usage-sensitive basis (x cents/minute).

Clear Channel
NextLevel Internet dedicates a portion of its network for the exclusive use of a single customer, ensuring enough bandwidth is always available to serve the customer's needs. Clear Channel features a non-switched 'always on' service, carrying voice, data, or video across NextLevel Internet's managed and fully-upgradeable local, national, and international networks. Also referred to as Private Line Services.

Co-Location
A service in which a company can have their servers housed inside the computer room of a facility directly connected to the Internet. Co-Location offers the ability to create an international business presence. Our infrastructure features diverse, redundant connectivity directly to other major Internet carriers and regional traffic exchanges.

Cookies
A data structure sent by web servers to client browsers used for retaining information about the client. The client's browser accepts a file, or cookie, from the web server. The client stores the cookie for a length of time determined by the configuration settings of the client browser.

Cross-Connect
Cross connects can help clients link equipment from cabinet-to-cabinet, rack-to-rack, client-to-vendor, peer-to-peer.
