3. Evolution of GNFT network.
IP evolution
DSO (Distribution System Operator) features:
Sites: 380 substations & 38.000 secondary substations.
Services: telecontrol (590 substation, ≈ 3.000 sec. sub), 192 protections.

4. Strategy of migration to IP.
• 1999: no IP network. CPEs connected via point to point circuits or PVCs (FR) PVCs.
• Phase #1 (2002-2004): satellite platforms for “anywhere connections” and deployment of
MPLS core network (VPNs, VPLS). Objective: control of critical services, service ubiquity, and
resell surplus capacity.
• Phase #2 (2008): spread of native ethernet/IP connectivity to main substations (IRIS
network). Objective: to have the infrastructure ready for DSO services, providing ↑ speed, and
redundancy. The network deployed was based on industrial L2/L3 switches connected by
1 Gbps fiber optics trunks.
• Phase #3 (2011): to extend ethernet/IP connectivity to 75% of secondary substations by
2018. Objective: to be able to provide the services required (smart metering, telecontrol,
advanced distribution services (Ground Fault Detector, Partial Discharges, …). The network is
based on a mix: GPRS/3G devices, optical connections, and BPL technology.

5. Examples of projects.
VPN MPLS SEG
IP connectivity for critical services
(gas&electricity).
Secure design (Hub&Spoke),
avoiding traffic between “spokes”.
It permits any access technology
(VSAT, GPRS, ethernet, TDM).
It permits different levels of access
redundancy (2CPE-2PE, 1CPE-1PE).
Hubs (Data Centers) Access Spokes (Energy Sites) Access

5. Examples of projects.
Telecontrol using VSAT
Back-up of telecontrol via VSAT.
105 RTUs using IEC 60870-5-101.
IEC 101 is encapsulated to TCP/IP
at Scada but also at the RTU side.
Once IEC 101 is encapsulated to IP,
It’s routed through the satellite IP
platform.
Encapsulation is transparent for RTU
Scada.

5. Examples of projects.
IRIS Network
IP/Ethernet connectivity to 203
substations distributed in 7 rings.
Hiper Ring protocol is used to
rebuild traffic (<500 ms).
1 Gbps trunks over fiber optic.
Provides security between the
critical services and office data.
It provides data transfer limitation
for the access.

• 1 CPE/site x 2 mobile operator conn. avialable.
• Full IP management: L2 mobile service.
• Same configuration for all sites&mob. operator

7. Upcoming projects.
BPL (Broadband Power Line)
• Trial Q3 2013.
• High capacity (up to 200 Mbps).
• Useful to extend FO network for critical services (control).
Carrier Ethernet
• Objective: migration of PDH/SDH services.
• Integration of packet-based and circuit-switched networks.
• Allow traffic engineering (MPLS-TP).
• Legacy interfaces: E1/T1, X.21, V.35, RS232, G.703.
LTE (Long Term Evolution)
• Lower latency than GPRS/3G.
• QoS end to end.
• IP end to end.
• Higher capacity.
• Better coverage (↑ efficiency).

8. Main challenges.
Security
Critical infrastructures → intregrity, availability, obedience, authentication, encryption.
Flexibility
The network must meet any service topology (vertical, horizontal,
mesh,…).
QoS
The private/public networks must provide “secured capacity” for critical services.
Integration
New networks must integrate all kinds of services/interfaces.
Provisioning
Due to the large number of devices, provisioning must be simple,
“automatic”, and executed by no “IT technical staff” if neccesary.
Technology life cycle
Lifetime of utilities investments is becoming much longer than
technology life cycle (PDH/SDH, GPRS).Utilities services and
networks don’t represent a significant share of the market.
