SLA
Service-Level Agreement
This is an agreement that defines the allowable time in which a party must respond to issues on behalf of the other party.
CARP
Common Address Redundancy Protocol
Provides IP-based redundancy, allowing a group of hosts on the same network segment (referred to as a redundancy group) to share an IP address.
VRRP
Virtual Router Redundancy Protocol
Provides IP-based redundancy, allowing a group of hosts on the same network segment (referred to as a redundancy group) to share an IP address.
HSRP
Hot Standby Router Protocol
Provides IP-based redundancy, allowing a group of hosts on the same network segment (referred to as a redundancy group) to share an IP address.
DLP
The Data Loss Prevention policy defines all procedures for preventing the egress of sensitive data from the network and may include references to the use of data loss prevention (DLP) software.
MDF
Main Distribution Frame
Connects equipment (inside plant) to cables and sub
scriber carrier equipment (outside plant).
IDF
Intermediate Distribution Frame
Serves as a distribution point for cables from the MDF to individual cables connected to equipment in areas remote from these frames.
NDA
Nondisclosure Agreement
An agreement between two parties that defines what
information is considered confidential and cannot be shared outside the two parties.
UPS
Uninterruptible Power Supply
These devices can immediately supply power from a battery backup when a loss of power is detected.
PDU
Power Distribution Units
Simply provide a means of distributing power from the
input to a plurality of outlets.
HVAC
Heating, Ventilation, and Air Conditioning
Fire Suppression
Wet pipe

Cold Site
A cold site is a leased facility that contains only electrical and communications wiring, air conditioning, plumbing, and raised flooring.
Warm Site
A warm site is a leased facility that contains electrical and communications wiring, full utilities, and networking equipment.
Hot Site
A hot site is a leased facility that contains all the resources needed for full operation. This environment includes computers, raised flooring, full utilities, electrical and communications wiring, networking equipment, and uninterruptible power supplies (UPSs).
Cloud Site
These are sites that, while mimicking your on- premises network, are totally virtual, as shown
MTTR
Mean Time to Repair
This value describes the average length of time it takes a vendor to repair a device or component.
MTBF
Mean Time Between Failure
Describes the amount of time that elapses between one failure and the next.
RTO
Recovery Time Objective
This is the shortest time period after a disaster or disruptive event within which a resource or function must be restored in order to avoid unacceptable consequences.
RPO
Recovery Point Objective
RPOs measure back in time to when your data was preserved in a usable format, usually to the most recent backup.
SDSL
Symmetric digital subscriber line
