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

• Smaller antenna.

14

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.
