1. The road to real convergence
ATM’s achievements
BiLAN ATM/FR
..Multiprotocol: Any Layer 3 protocol
.Multiservice: Special AALs for voice, video,
data, … with specific QoS characteristics
.High availability: Strong OAM mechanisms,
static and dynamic protection mechanisms, …
.Single platform for business and residential
applications
.All DSL technologies are ATM-based today
.No end-to-end functionality . ATM never
reached the desktop
.Mapping IP QoS into ATM QoS remains
difficult/limited
.Any-to-any via hub and spoke
.Multicast stays on the IP level, not on the
network level
ATM provided good convergence possibilities in the WAN, but never
came close enough to the applications

IP-VPN/MPLS achievements
.End-to-end functionality: IP from the
desktop over the LAN to the WAN
.Multiservice: MPLS contains strong QoS
mechanisms, and IP QoS values are easily
mappable in MPLS
.High availability: Fast reroute mechanisms,
advanced routing protocols, …
.Easy integration of DSL technologies
.Native any-to-any technology
.No multiprotocol: IP only
.Platform only used for business applications,
never evolved to the residential market
.Multicast applications are rather complex to
support
BiLAN IPVPN
IP-VPN over MPLS gives perfect end-to-end convergence solutions
for all IP applications in the business market

Conclusion
. Belgacom explore is not just about technology anymore
. Everything becomes MPLS, IP & Ethernet
. Outphasings of traditional network technologies (SDH, PHD, ATM,…)
. Network & product simplification
. 1 single network infrastructure
. It is about:
. increasing application availability
. Improving business continuity
. Maximizing employee productivity
. Reducing costs
. Reducing complexity
. Boosting innovation
. And revitalizing the value-chain
There’s a whole world to discover !
