NETWORKS AND SERVICE PLATFORMS
8.1.8 Networks dedicated
to Business Services
X.25 Networks
In France, the X.25 network connects several thousand direct
X.25 accesses, several tens of thousands of Channel D ISDN
accesses, access to electronic payment systems, and supports
Intelligent Network services. An optimization program is
currently being carried out.
Frame Relay/ATM Networks
In France , the Frame Relay/ATM network is both a network
for accessing services dedicated to business (particularly
through the TDSL aggregation offers) and a backbone transport
network for layer 3 services (X.25 and IP). It is used in around
150 points of presence in mainland France, in the four overseas
departments and in three overseas territories (Mayotte, New
Caledonia and French Polynesia).
This network is interconnected with Equant’s AGN (ATM Global
Network) network via two ATM gateways located in Paris, which
provide Frame Relay and ATM services at a worldwide level.
The activity on the FR/ATM network is declining, and the
businesses’ need for increased speed is now met by the IP/
MPLS services available on the “Network for Business Access
to IP” (NBAIP).
Outside France, Equant’s AGN network covers around a
thousand points in approximately 200 countries. It provides
X.25, Frame Relay and ATM services, but is mainly used today
as an access network to IP services, because of its extensive
worldwide capillarity. It also provides a transport function for
the IP network, but this function is gradually diminishing as the
native IP network develops.
The Network for Business Access
to the Internet (NBAIP) in France
The main purpose of the NBAIP is to connect a company’s sites
for internal data exchange (on the Virtual Private Network (VPN))
and to provide them with Internet connectivity. It also provides
Voice over IP transport for companies.
It is made up of a core infrastructure of around sixty transit
routers called “P_Pass” that are interconnected by 10 Gbps
links. This P_Pass network backbone also provides the
interconnection with RBCI for Internet traffi c and for business
collection traffi c coming from NAS and BAS.
In addition, a ring of approximately 500 PE (Provider Edge)
routers gives companies access to xDSL and Ethernet or Frame
Relay and ATM technologies, at speeds of 75 kbps to 30 Mbps,
under standard offers. A new generation of PE routers, the
HSPE (High Speed PE), whose roll-out will be complete in 2010,
provides access of around Gbps (or more in custom offers) in
major cities.
The NBAIP also makes it possible to connect a company’s
service platforms at speeds of around one Gbps (SE – Service
Edge infrastructure).
This network is connected to Equant’s international IP network
(IP Global Network) through three gateways (located in Paris
and London) to connect international business customers.
The MPLS/IP VPN Network
(IP Global Network, or IGN)
Like the IP network in France (NBAIP), this network is designed
to supply virtual private network (VPN), Internet and Voice over
IP services. These VPN services are available at around 1300
points (including partner MPLS networks) in roughly 900 cities
in more than 150 countries.
The network core is made up of dozens of network core routers
(P routers and similar) and several hundred access routers (PE
routers). The services are offered either directly on the access
routers, or through the Frame Relay/ATM access network.
France Telecom is updating the access routers to provide a
multi-services platform (Ethernet, DSL, FR/ATM).
Note that in Europe, there has been signifi cant network core
development, with commissioning of the EGN network (Ethernet
Global Network), which has around ten points of presence in six
countries. EGN uses France Telecom’s broadband network (10
Gbps) and offers point-to-point services (E-line services) and
multipoint-to-multipoint services (VPLS-based services) with
customer access of up to 1 Gbps.
