Policy, location, routing, and response quality connected in one operational model.

Core NG112 Architecture

ESInet

Emergency Services IP Network

An ESInet is not the public internet. It is an engineered IP service environment with controlled interconnects, security boundaries, routing functions, monitoring, redundancy and operational governance. European implementations can be national, regional, federated or transitional, so the term should describe the function and assurance model rather than imply one identical deployment pattern.

ESInet is not simply the internet; it is a controlled emergency-services IP network with operational policy, security and availability requirements.

What it does

An Emergency Services IP Network is the managed emergency-services network that carries IP emergency sessions and related data between originating networks, routing functions and PSAPs.

The ESInet provides the trusted transport and service layer where emergency sessions can reach routing, validation, security and PSAP functions.

How it works

Carries SIP emergency sessions and associated data across a controlled emergency-services IP environment.
Hosts or reaches routing, validation, security and operational monitoring functions.
Supports redundancy and alternate routing so a single site or path failure does not strand emergency calls.

Key interfaces and protocols

SIP/SIP over TLS
IP routing and QoS
DNS/service discovery where used
Operational monitoring interfaces

Systems it interacts with

BCF
ESRP
ECRF
LVF
PSAP
Originating networks

Common failure modes

Loss of interconnect capacity
DNS or certificate failures
Misrouted traffic after policy change
Single-region dependency hidden inside a national architecture

Implementation considerations

Define national versus regional ownership clearly.
Test failover across real PSAP paths, not only lab proxies.
Document which functions are inside the ESInet and which remain in originating networks.
