IPRM – Fundamental Concept (II)! Terminal becomes moving

network

! TE-Engineered tunnel becomesone hop

! Wireless “access” link becomesone hop

! Wireline “access” link(xDSL/PON/ETH) becomes onehop

!

Service / User specific metricsper hop

! Routing protocols used formetrics distribution

! TE algorithms exploit metrics forforwarding decisions

! Full integration of multi-interfaceterminals

! multi-path routing

IPRM - ExamplesIPRM is open for more

concepts like

!

„load sharing“ viadifferent mobileinterfaces

! (Network) MIMOconcepts are feasible

! Efficient personalmobility

! Smooth integration ofmulti-hop and ad-hocnetworks

! New deploymentscenarios (e.g. UMTSat home)

Migration Issues...Seamless service continuity for a

moving “legacy“ mobile isrequired!

Three Aspects:

(a) Interworking between UMTS

Network ans Access Domain(b) Interworking between

“legacy“ mobile and UR

(c) Mapping of “legacy“ mobile

into IPRM architecture

Summary and OutlookSummary:

! Application vs. network convergence

!

Architecture build upon the ideas of IPRM – Unified resource and mobility management

– Efficient routing

! Migration path essential part of concept

Lucent focus in ScaleNet project:

! Design of efficient routing protocols and algorithms to supportIPRM (Control plane handling within Access Domain)

! Efficient Transport of user traffic (User plane handling within Access Domain)

! ScaleNet Demonstrator
