08-506 ESIND working groupJim Lockard, Joel McCamley

Co-Chairs


Objective

Discuss 08-506 ESIND work group

Update on progress

Seek additional WG membership

Provide schedule


What is the purpose of 08-506 ESIND

Informational document

Meant to provide guidance

Not a standard

Identifies high level technical areas for

all ESInets

Planning support

Foundational ESInet criteria


08-506 ESIND overview

Covers the design of ESInets at OSI layers 1, 2, and 3

Reliability and availability service levels are discussed

Performance requirements

Service level agreements for operators

Aspects of network security

Prioritization

Traffic engineering

Network management and monitoring


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.

Utilization of the ESInet



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


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



OSI Layer 1

Copper

Fiber

Coax

Wireless – 3G, 4G, 4G LTE

Microwave

Satellite



OSI Layer 2

HDLC – T1/T3

Frame Relay

Asynchronous Transfer Mode (ATM)

Metro Ethernet

Multiprotocol Label Switching (MPLS)



OSI Layer 3

IP Addressing

Dynamic Routing Protocols

Interior Gateway Protocols



Availability and Reliability

Provides definitions of each

Achieving 5 “9’s”

Achieving availability and reliability in legacy

PSAPs

Definition of failure metrics

Discussion on Series and parallel availability

and reliability



The NENA 75-001 Security for Next-Generation 9-1-1

Standard (NG-SEC) contains a number of sections which

apply to ESInets including;

Security Policies

Information Classification

Safeguarding Information Assets

Physical Security Guidelines

Network and Remote Access Security Guidelines

Change Control Documentation

Compliance Audits and Reviews



ESInets should be NG-SEC compliant

Session Border Controllers

Internet Access within a PSAP (NEW)



Network Management and Monitoring

Discusses operational and administrative

configurations and functions

Performance Requirements

08-506 ESIND - support

We welcome additional WG members from

the PSAP community

Interested in gathering information about the

Operation and Administration of ESInets

WG is seeking more vendor community

involvement

Interested in gathering more “real world” /

“real experiences”
