Vision on the best packet optical platform
• Multi-layer switching platform – WDM (colour-less, contention-less, etc.)
– OTN
– Packet
• OTN switching – Fill-in the high speed waves
• Packet switching – MPLS switching (LSR)
– No LER (VPN, VPLS, GRE, MC), no BGP
– CP protocols (IS-IS, OSPF, TE, LDP, RSVP)

• Limited interworking needed
• Easy end-to-end management
• Proprietary options to fill gaps
• Offers most services today
• 2006 was too early for modular
• Missing standards to fuel concept

• Incremental vs [color]field

So what’s the future like ?
• Ethernet is the de-facto access technology for WAN and DC LAN
• Monolithic MSP/CE solutions are going to be history soon: modular,
multi-vendor (i.e. IP like) will be the new norm. As well as integrated
networks
• Openness, APIs, programmability will prevail over hardware
capabilities: need to re-invent OSS and introduce more network
functions virtualizations
• Not just bandwidth/features will change in-life, also the service type
• Platform v2: managed IT solutions will include and abstract the
network, compute&storage changes and multiple markets
propositions
• New operating models for well established carriers and people
