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)

• Incremental vs [color]field

28

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
