FG IMT2020 resultsan inheritance not to be wasted
The FG was created to the purpose of conducting pre‐standard activities on fixed access/transport and core network aspects of 5G, including management and controlFG IMT2020 concluded its activities at the end of last year (i.e. less than 2 months ago)9 documents delivered to SG13 as a basis for the production of standards on 5G

The future Internet
SecureProvides high availabilityTransfers data independent of locationTakes advantage of storage and processing
10
Compliance to the following requiremnts
Enabled applying some basic principles
All data are NamedAll data are Secured Communications are based on names
• Enables facing the dominating source of traffic in the networks : VIDEO, improving delivery time and reducing trafficover the network
• Optimises delivery performance (DELAY) asdata are closer to the user
• Network nodes have data stored dynamicallyaccording to interest and need
• Important application in emergency services for tracking of users
Essential concepts
Use of hierarchical names to identfy anything in the network (servers and clients, in particular) instead of IP address and port
Distributed contend and distributed routing tables for servicesenable shorter path computation for information delivery
ICN can provide intrinsically multicast capabilities
ICN can be deployed standalone or as overlay or underlay for TCP/IP networks or any transport
Improve security wrt CDN based services (redirecitions)
Support Mobility better than with the ‘homing’ approach and natively
Support both end user and producer’s mobility
Essential benefitsLatency‐reduction via in‐network control and hop‐by‐hop dynamic forwarding Better user experience with transport cost reduction via edge caching/processing Unified unicast/multicast communication Improved security/confidentiality, flexibility to support different models Simplified core network architecture (e.g. through built‐in L2‐agnostic anchorless mobility support)Seamless communication over an hetherogenous and mobile access through connectionless receiver‐driven natively multipath transport Richer network‐aware content analytics

The next logical step: Dynamic Web Servers, spun up possibly just one hop away• Creates new service possibilities for operators, utilizing in‐network NFV‐based computing capabilities
• Helps meeting challenging 5G KPIs, such as 5ms service‐level latency & 1000x capacity increase

• Implementing essential ICN features:• distributed hop‐by‐hop stateful forwarding, • connectionless communications, • object‐based security
• Implement ICN with well known APP layer protocol (DASH)
ICN(like) approaches: Function Chaining Networking
16
Improvement evolution fromNFN 3‐phase strategy to process a functional chaining request
upstream fetch, separate code and data fetch, computation push
From producer to consumer Data retrievalComputation functions to optimisedata delivery
Application of ICN to mmWave radio: spotty networks
Using ICN content is transferred quickly from edge cloud storage, with trusted source encryption and signature, allowing the use of micro and nano cells with ultra high BW
17
Source: KDDI
ICN native or overlay deployment
ICN can be implemented replacing the TCP/IP stack completelyor in an overlay approachIP can be also implemented on top of ICN where needed
18
Standard status
Several drafts in IRTF (proposed Experimental status)
Requirements document published and ongoing work in ITU‐T SG13
ICN is not one of the latest inventions nevertheless not much isgoing on in standards
ICN first concepts in new networking technology: Data Aware Networking (DAN) ‐Y.3071‐
20
Approved Recommendation on high‐level architecture for ICN
NDO: Named Data Object
Network Capabilities :• Data• Control • Security • Management • Application
(network service)
ConclusionsSome 5G main points as: full mobility, high bandwidth, very low latency, high security, can be addressed implementing new networking paradigms
Information Centric Networking is one possible solution levearging on data cashing in network nodes and naming of resources, nodes and users
Support of security by design
Implementations by many major players addressing different aspects as mobility, latencyand interplay with different networks and access starting from the same baseline concepts
Naming of resources, users and content
Cashing of content and processing on nodes
Securing of data
Standard development is still at a very early stage, nevertheless it has started
IRTF has work in progress
SG13 in ITU‐T published the first recommendation with the requirements for ICN (Y.3071)
Work is in progress in WP1/13, with new recommendations in plan for early 2018
