Achievements

Task 2: Cloud Architecture (g) Open Cloud Exchange concept

Direct service/inter-member peering

–

Re-use and leverage Internet eXchange

–

Open collocation services

–

Scalability for growing number of members

–

Controlled network parameters/QoS

No third party (intermediary/broker) services

–

Transparency for cloud based services

–

No involvement into peering or mutual business relations

Trusted Third Party (TTP)

–

Support dynamic service agreements and/or federation

–

Trusted Introducer for dynamic trust establishment Future support of special services

• Delivery and integration between CSP and Customer
• Local policies, service registry and discovery

Network Architectures for Horizon 2020 Achievements

Task 1: Network Architecture

Model 1 Model 2 Model 3 Layer 3: Network Layer, Routing Layer 2: Ethernet/ Carrier Ethernet “Frame Switching” Layer 1: OTN switching @ ODU levels Layer 0: Photonic Layer, add/drop , λ-switching

1 Tbps 1 Tbps

Network Model?

• Still no clear path forward

–

Layer 0 integration with Layer 3

–

Layer 1 & 2 integration

• Where to do the switching and

switching granularity? Enablers For Big Pipes

• Coherent transmission (QPSK, QAM, etc.)

– Several bits per symbol

• Efficient use of spectrum – superchannels

Close collaboration with Open Call projects:

• COFFEE
• REACTION
• MOMoT

Achievements

Task 1: Roaming – maintaining the leading edge

SyncE PTP GPS NTP

• TDM transport technologies are replaced with Ethernet in WANs
• Intrinsic timing / framing reference is no longer available

Longer-term perspectives

• PTP as part of Audio Video Bridging?
• Video transmission with QoS over heterogeneous networks
• How to ensure correct

time synchronisation?

• How accurate is PTP?
• Requirements of

number of slaves? Challenge for Next Generation Networks / Services
