Strategic Planning and Solution MappingStrategic Planning and Solution MappingNetwork Network ModelingModeling for planningfor planning

• High complexity of the whole Network requires a mo deling and

splitting in subnetworks to facilitate analysis , de sign and planning.

• By Layers in a vertical dimension following the client-server

relation (one layer is supported in the layer below and provides

resources for the layer up). Physical, Transmission, Switching, etc.

• By Segments or splitting of the end to end communication into

sub-areas as customer premises, access, core national, core

international

• By Technologies or underlying technique as SDH, WDM, ATM,

IP, IMS, GSM, 3G, WiMax, etc.....

– New traffic models needed to represent multiservice flows

– New dimensioning methods for resources handling multimedia

services with QoS

– New measurement procedures for aggregated multiservice traffics

– New multicriteria dimensioning for 3G, xG and BWA combining

coverage by frequency, service speed and data traffic capacity

– Procedures to ensure interoperability and end-to-end performance

across multiple domains


Strategic Planning and Solution MappingStrategic Planning and Solution MappingMultiservice Traffic flows for QoS based dimensioning

– C1) QoS constant stream : bandwidth transmission at a constant speed with a specified delivery and jitter (ie: CBR, SDH, video distribution)

“peak rate” models

– C2) QoS variable stream : bandwidth transmission at a variable speed derived from a user information and coding algorithm which requires guaranteed quality and specified jitter (ie: VoIP, Video streaming, audio streaming, etc.)

“multirate-erlang” models

– C3) QoS elastic : bandwidth transmission at a variable speed without jitter restrictions and asynchronous delivery (ie: browsing, file transfer, mail, UMS, etc.)

“processor sharing” models

Strategic Planning and Solution MappingStrategic Planning and Solution MappingArchitecture Consolidation: TopologyArchitecture Consolidation: Topology

Topological changes impact on infrastructure and are slower to implement than technology substitution

• Less network nodes and links due to the higher capacity of systems (one order of magnitude).

• Same capillarity at access level due to identical customer location

• Topological connectivity higher for high capacity nodes and paths due to security

• High protection level and diversity paths/sources in all high capacity systems, both at functional and physical levels



• Network Planning: Types, Requirements and activitie s

Procedure:

• Characterize variety of geo-scenarios within the country in customer

density and services demand

• Define and estimate key parameters per scenario and solution

• Techno-economical evaluation to minimize Cost of Ownership and

maximize benefits

Objectives: Associate best technologies to serve an d compete at

each geo-scenario

Strategic Planning and Solution MappingStrategic Planning and Solution MappingRecommendation for AccessRecommendation for Access

Access dominated by physical infrastructure cost an d deployment time

• Quick deployment of DSL and Multimedia Services on existing infrastructures

• FO closer to customer (FTTH, FTTC) when implementing new outside plant or renovating existing one

• New Wireless technologies: WiMAX for low density customer scenarios and niche areas.

• Shorter LL length and cell radius than classical network to be prepared for high bandwidth Multimedia services


Strategic Planning and Solution MappingStrategic Planning and Solution MappingReference benefitsReference benefits

• Adequate definition of customer segments, services and

business to ensure efficient operation in competition

• Anticipation of 2 to 3 years in the positive IRR

• Saving factors of 20% to 200 % by best

solution/technology mapping in the access segment

• Additional gains between 20 to 40 % by topology/routing

optimization
