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

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
