IT Spend Optimization

e-company enabler

Delivery excellence Risk mitigation

Main supporters:

Finance, B2C


E-Company Technology Enablers 1/2

Flexible end-user services

E-Company Enablers Delivered by IT Transformation

§ VDI (Virtual Desktop Infrastructure) - Strategic centralization of desktop services provides value to organizations by

making end-user computing environments more secure, reliable and easier to support.

§ BYOD (Bring Your Own Device) - allows employees and contractors to use their favorite device for work

Related measure: VDI, BYOD

Social Enterprise, Collaboration and Process Automation

§ SharePoint 2013 Deployment – Upgrade to latest version of MS Sharepoint will provide various collaboration and social

capabilities. NetDMS project is piloting business process automation on top of MS Sharepoint.

Related Measures: ECM platform consolidation program, Knowledge sharing and Social Enterprise


E-Company Technology Enablers 2/2

E-Company Principles implemented internally within IT processes

IT Transformation applies e-Company principles also within IT organization.

Automation

§ Environment Management - Introduce tool and methodology for transparent and time limited allocations

of non-production environments towards automated environment provisioning and self-service tools

§ Development, Test and Operation Automation – Automation of routine tasks in order to reduce effort

and increase quality

Related measures: Non Production environment Management, Development Automation, Test automation,

Operation automation

§ Service Automation and Inventory data correction

§ Service Automation in OSS – TFC from system, less rollbacks, less technician in field, shorter

installation lead times, single inventory

Related Measures: Service Automation and Inventory data correction






WHY INTEGRATED ACCESS STRATEGY


• Digital Agenda for Europe 2020

100 Mbps or more for 50% of HHs, 30 Mbps or more for all HHs

• Cost reduction (provisioning & fault clearance, buildings, energy, overhead)

• Necessity to enable to provide high speed BB services capable to compete in BB services according

to customers' needs in term of speed & quality & geographical footprint, constantly growing data demand

• Shortcomings of metallic access network concerning BB services:

•Insufficient quality for new/intended high speed services

•High quantity of faults, complicated topology & fault elimination

•Limited cable utilization due to physical limitations (e.g. interferences)

• True Fix/Mobile synergy effect thanks to optical network deployment (F2BTS) and Hybrid CPE usage

HIGHER BANDWIDTH DRIVES SALE AND CUSTOMER DEMAND

Od TDM technológií k All IP, od hlasových služieb k internetu a televízii Stanislav Dzúrik

Source: FCC, US market expectations, 2011

Customers are not interested in lower speed BB products when offered

higher speeds by the competition:

• 30 Mbps in 2020 will be just minimum BB (as 5 Mbps today)

• Average BB for 50% and more HH should be over 100Mbps

• Premium B2C customers >200Mbps, in cities 1Gbps

• For average B2B in 2020 we can already expect 1Gbps

• Lower BB access below 100Mbps will be BEHIND a hype significantly decreasing

after 2020

Smart Home, Video and OTT services will drive

demand:

• Video services rules (over 60-80% traffic)

• Ultra HD(4k TV), Multi-screen services (see HH

average)

• Connected devices (millions)

• Applications in the Clouds

• Social and OTT communications 0

ACCESS TECHNOLOGY EVOLVING IN MOBILE AND FIXED


§ Implement FTTC/B (VDSL)/FTTH (GPON) technology

§ Optical deployment is used also for mobile sites

backhauling and hybrid access

§ To be able deliver 1Gbps customer access is requiring to

implement FTTH (GPON) technology

§ Modernize network to flexible bandwidth developing a

DWDM infrastructure (upgrade DWDM to 100G)

§ Capacity extension and boost by new RAN and LTE-A

§ With LTE and LTE Advanced requests capacity boost

-> backhauling over fiber

§ Mobile traffic growth depend on deployment of small

cells (smaller cells need fiber connection)

§ Fiber for wireless backhaul and mobile offloading

§ Optical coverage 362 000 HHs (apx. 19% of all HHs in Slovakia)

§ Main coverage done in 2008 (Project No.1)

§ Robust & complicated DP structure (MDF, TR, SR, UR, PUR)

Deploy fiber to the most economical Point 1


Exploding Bandwidth ! Universal Broadband Service ! I am convinced I need to bring fiber closer to my customers but … What is the best approach? ü Fibre-To-The-Home directly? ü Fibre-To-The-Node with re-use of existing copper pairs for the last km? ü Fibre-To-The-Building with re-use of existing in-building cabling? ü Fibre-To-The-Distribution Point with copper or small cells for the last drop? ü GPON? Vectoring? G.Fast? … ü Or… combining all of these?

Economical considerations rule the decision process !!!

• Transparent to applications/users: Two GRE tunnels are bonded to one logical IP channel

• Bonding Group makes buffering and re-ordering for packets in uplink direction

• CPE makes buffering and re-ordering for packets in downlink direction

• Robust networking experience: load sharing & automatic switchover in case of one link failure

• Policy server sets rules which streams would run in by-pass mode

TECHNOLOGY 1: FTTH GPON

Pros

FTTH solution, passive optic infrastructure

Cons Suitability

• 1G+++ speed per customer

•No need for parallel metallic infrastructure

• No power required – only passive

components are used

• One optical fiber per 64 customers

•Low number of active node locations (OLT).

• To reach the target (Cu-to-optical

migration), the whole area has to be

migrated

• Due to splitting ratio, available access range

20km only (for splitting ratio 1:64)

• Fiber termination (installation) at customer

premises needed incl. in-house cabling

• Localities with no metallic AN (new

localities, building after reconstruction, etc.)

• Localities with poor quality and/or

undersized metallic AN


TECHNOLOGY 2: FTTB GPON

Pros

FTTB solution, metallic+optic infrastructure

Cons Suitability

• No new in-house cabling installation needed

• Vectoring possible (VDSL2+, G.Fast)

• Use of self installation packet possible

• Due to splitting ratio, available access range

40km

• Mainly for block of flats (i.e. towns with

more than 20ths. inhibitans )

• New residential areas/customers with loop

length up to 200m concentrated into one

distribution point.
