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

ICN ESSENTIALS


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

ICN POC

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
