What is an ESInet?
An ESInet is a managed IP network that is used for emergency
services communications, and which can be shared by all public
safety agencies.
It provides the IP transport infrastructure upon which independent
application platforms and core functional processes can be deployed,
including, but not restricted to, those necessary for providing NG9-1-1
services.
ESInets may be constructed from a mix of dedicated and shared
facilities.
ESInets may be interconnected at local, regional, state, federal,
national and international levels to form an IP-based inter-network
(network of networks).

What is NG9-1-1?
NG9-1-1 is an Internet Protocol (IP)_based system
comprised of managed Emergency Services IP networks
(ESInets), functional elements (applications), and
databases that replicate traditional E9-1-1 features and
functions and provides additional capabilities.
NG9-1-1 is designed to provide access to emergency
services from all connected communications sources,
and provide multimedia data capabilities for Public
Safety Answering Points (PSAPs) and other emergency
service organizations.

08-506 ESIND overview
The intended audience for this document includes network
architects that are tasked with designing ESInets and 9-1-1
Entities or state authorities that are working with
consultants and service providers to procure an ESInet
Provide 9-1-1 entities and state authorities with the
background information necessary to identify their
requirements
Define the concepts and vocabulary
08-506 ESIND does not (by itself) provide all of the
necessary details to properly design ESInets

Meant to be used in conjunction with Standards documents, not
as a substitute for them
A summary of the core requirements for an ESInet are included
in the NENA 08-003 v 2.0 Detailed Functional and Interface
Specification for the NENA i3 Solution – Stage 3 are as follows:
The network between the PSAP and the ESInet will be a private or
virtual private network based upon TCP/IP
It will have scalable bandwidth to support new enhanced services.
The Emergency Services IP Network shall be a conventional routed
IP network
MPLS or other sub-IP mechanisms are permitted as appropriate
N E N A D e v e l o p m e n t C o n f e r e n c e | O c t o b e r 2 0 1 4 | O r l a n d o , F l o r i d a
08-506 ESIND overview (cont)
The PSAP should use redundant local area networks for
reliability
PSAP LAN to the ESInet must be resilient, secure,
physically diverse, and logically separate
The ESInet shall be engineered to sustain real time
traffic, including data, audio, and video
Connections between the PSAP and ESInet shall be
secured TCP/IP connections
ESInets should be capable of operating on IPv4 and IPv6
network infrastructures
