InterDigital Europe – Open for Business July 2013
© 2015 InterDigital, Inc. All Rights Reserved.
Central mission is to drive technology collaboration & partnership initiatives in the areas of 5G & IoT across the European stage
Happy to call London and “Tech City” our home affording us easy access to anywhere in Europe
We play in Horizon 2020, 5GPPP, Innovate UK and are always looking to create new projects and alliances
Already seeing some good results with Eight Wins in EU competition (e.g. H2020) so far
Also driving a integrated transport initiative, oneTRANSPORT in the area of the IoT

POINT: A FLEXIBLE Twist on Information Centric Networking
Content Management built into the core fabric of
the system
POINT is a EUH2020 Research & Innovation Programme Funded Project under grant No. 643990
What is Information Centric Networking (ICN)?
• We think it is simply an inevitable destination • A paradigm shift away from client-host comms • Focus is on content & name based addressing • Brings pub-sub model to core networking Benefits and Challenges of ICN
• Better utilization through native multicast! • Better privacy and path resilience to failures • But changing the internet is really difficult! • But that was before SDN/NFV came along

The Problem & Current Approaches

Bandwidth costs
HTTP Unicast Proliferation
# of User Connections
# of user viewings determine BW costs
Two current approaches – Two shortcomings
• CDNs are currently used for popular content but this is overly complex and results in inefficiencies associated with indirections
• Overprovisioning of resources drives unsustainable spiraling costs
Both shortcomings are unsustainable for 5G

POINT/RIFE: The Innovative ICN approach for competitive 5G (or before) operator networks
• Re-introduce multicast into world of predominantly personalized web experience -> higher network utilization
• Flexible routing at runtime through cloudifiable software elements -> increased resilience, latency reduction

5G-Crosshaul – Motivation
• @High Level: An ambitious set of 5G KPIs (e.g. capacity, latency, efficiency) to deliver at a time network operators are looking into ways to reduce costs (TCO) and expand the service offer!
• @Fronthaul: Evolve from today’s CPRI or CPRI-like to less-stringent (in terms of capacity, latency, jitter and cost) and scalable solutions that can cope with the high (small cells) densification and (massive) MIMO technologies foreseen in 5G: Access Virtualization through flexible functional split between the RU and DU.
• @Backhaul: Evolve from today’s cascade of increasingly heterogeneous and independently managed technologies to a truly integrated transport that is flexible to adapt to various 5G requirements (capacity, latency): Technology-abstract joint orchestration over common SDN-based control.

Goals of the Project
• 5G-Crosshaul project aims at integrating Fronthaul and Backhaul for envisioned 5G Virtualized RAN architectures
• The integration is tackled in both the control and data planes • A common SDN/NFV-based control infrastructure (compatible with ODL/ONOS
SDN and ETSI NFV architecture frameworks) • A unified data plane with common switching of FH and BH traffic across
heterogeneous technologies
• The data plane focuses on Carrier Grade Layer-2 packet switching (XCF) • Ethernet-based PBB-TE and MPLS-TP as candidate baseline templates for
support of legacy switches (backwards compatibility) • New instantiation of the above templates for new switches (XFE)
• Standardization roadmaps include relevant working groups in IEEE, ITU-T, 3GPP, IETF, ONF, and ETSI (amongst others)
• First trials demonstrations are planned in Berlin in Sep-Oct 2016
