Next Generation Point of Presence

(NG POP): driver for DMM

July 2nd 2014

IETF::DMM Call #5

2 France Telecom Group confidential

Introduction

� PoP (Point of Presence): an organic network node

– local PoP: basically a traffic aggregation node

– Core PoP: hosting traffic anchoring and operator services

� A bunch of network evolutions is going to change the roles…


Ongoing Network evolution #1

� Access optimization

– FTTH: fixed access nodes concentration

– LTE: Cloud RAN – hosting baseband treatment in the network



� Virtual Residential Gateway

– Hosting box networking/services functions in the network

� Distributed CDN

– tremendous traffic growth (e.g. audiovisual content consumption)

– Optimized for transport network by flattening IP hierarchical

network, using caching servers in POPs

Move down BNG

already

deployed in

fixed networks



� CDN, local services – leads to: Distribution of

traffic anchoring in fixed and mobile networks:

– EPC and fixed gateways (BNG) distributed at

network edge

– SIPTO for macrocells

� 3GPP CSIPTO (Coordinated

SIPTO) Work Item

– handle multiple connections

to the same PDN

– with IP address preservation

or not

– ….

NGPOP: network node where fixed and mobile accesses are aggregated

NG-POP located closer to the end-user

Network as a

mediator/proxy

between users

and service

providers (M2M,

IoT, …)

Distribute contents and

application closer to user to

reduce latency and increase

bandwidthFunctional and

structural

convergence of fixed

Integrate Terminal

processing) in network

Local

NG-PoP

� Traffic Anchoring located closer to the end-user…


Conclusions :: NG-POP and DMM

� Much more network functions

hosted on the Local PoP

� Distribution of content delivery (e.g.

CDN distribution) can be taken as

granted

– and so, the traffic anchoring

point…. BTW, traffic anchoring

points of fixed network are

already distributed…

– so, distribute mobility anchor as

well

mobility concepts

no major technical issue

key issue: packet

distribution

management

Here, no assumption

regarding the location of

the aggregation function

Dynamic Splitting(ressource and QoE optimization)

IP mobility protocols

(NEMO, MIP, PMIP)

could be used to set-

up the datapaths

(e.g. RFC 4908)

Use IP mobility

protocols for their

features, but not for

mobility management
