Telco: andamento delle revenues negli anni ‘90

Dato disaggregato Voce vs. non-voce

• Le revenues generate dal traffico voce sono cresciute negli anni ’90,
per l’aumento del traffico mobile
• Il peso della voce nelle revenues totali è rimasto costante


Telco: andamento delle revenues negli anni 2000
Diminuzione costante delle revenues totali generate dal traffico voce
Erosione causata dai servizi VoIP (es. per le call long-distance)
Incremento delle revenues prodotte da
Traffico dati sulle reti broadband (P2P)
Servizi VAS
Servizi ICT Già oggi una importante fonte di revenue per alcune telco
I servizi VAS accessibili dalla rete PSTN sono ancora sotto il controllo
dell’operatore (funge da intermediario)
Servizi accessibili via Internet sono completamente non intercettati dai
telco (Amazon, EBay, PayPal, …)
Attenzione: ai telco non conviene essere solo trasportatori di bit, le
revenues prodotte dal puro trasporto di bit diminuiranno presto…

Next Generation Network
Source: ITU-T Rec. Y.2001
Rete di nuova generazione
a pacchetto,
multi-servizio,
abilitante la QoS,
convergente,
con una netta separazione tra gli strati di trasporto, di controllo e di
servizio.
Rete All-IP
Ruolo centrale di SIP per la segnalazione
Ruolo centrale del telco come intermediario per l’accesso ai servizi !


Next Generation Networks: vantaggi per utenti e telco
Convergenza e
Procedure e
sinergia tra i
strumenti comuni per
Service Provider
la gestione dei
servizi e degli utenti
abbonati

Procedure comuni
Convergenza
per il provisioning, la
Fisso-Mobile
gestione e la
tariffazione dei servizi
Accesso ai servizi
con garanzie di
QoS

Miglioramento della
User Experience
(Accesso ai servizi da un
qualunque dispositivo)


Cloud Computing: definizione del NIST
Cloud computing is a pay-per-use model for enabling
available, convenient, on-demand network access to a shared
pool of configurable computing resources (e.g., networks,
servers, storage, applications, services) that can be rapidly
provisioned and released with minimal management effort or
service provider interaction. This cloud model promotes
availability and is comprised of five key characteristics, three
delivery models, and four deployment models.
Characteristics: On-demand self-service, Ubiquitous network
access, Location independent resource pooling, Rapid elasticity,
Pay per use
Delivery: SaaS, PaaS, IaaS
Deployment: Private, Community, Public

Cloud Computing: mercato e player
Nuovi paradigmi per l’ICT
Software as a Service SaaS
Platform as a Service PaaS
Infrastructure as a Service IaaS
Caratteristiche comuni:
Terziarizzazione dei servizi e delle infrastrutture
Dimensionamento elastico
Modello on-demand
Fattori abilitanti:
Virtualizzazione
Reti broadband

Cloud Computing: SLA dei principali player
Amazon EC2
The Service Commitment does not apply to any unavailability,
suspension or termination of Amazon EC2, or any other Amazon EC2
performance issues ... caused by factors outside of our reasonable
control, including any force majeure event or Internet access or
related problems beyond the demarcation point of Amazon EC2.
GoGRID
This SLA does not cover (without limitation): (a) network performance
to Customer's physical location or internet access point (such as a
local DSL/cable modem); or (b) failures due to denial of service
attacks
RackSpace
You acknowledge that there are risks inherent in Internet connectivity
that could result in the loss of your privacy, Confidential Information,
and property

Telco e Cloud Computing
Several major telcos have recently announced their wish to enter the
cloud computing services market. During the past years, operators
have moved beyond broadband voice and data into network-
dependent applications like videoconferencing and telepresence and
have secured deeper enterprise relationships. Providing hosted
solutions to the companies is the next move many carriers are
considering today. Indeed, telecommunication providers could play
an important and lucrative role in the burgeoning world of cloud
computing by combining their natural advantages as network
operators with a new wave of technological innovation. The
opportunity represented by cloud-based services is potentially
immense because, for starters, it increases the value of carrier
networks in multiple ways and creates new roles and revenues for
telecom service providers.

First, clouds will increase network traffic and utilization and thus
transport revenues. Second, in physically delivering cloud-based
services, telecom carriers have an opportunity to extract two revenue
streams from the same function.
Moreover, emerging telco technologies such as IMS and next-
generation networks service architectures are developing into
logical service components that could also fit comfortably in
cloud environments.
A telco will have to acquire or develop hosting and managed
applications and combine that technology with Internet data centers. It
will then be able to offer managed networking, security, storage and
computing services. Its customers will be able to order on-demand
Windows and Linux environments, as well as most common software
applications, including Oracle and SAP.

January 2009: Deutsche Telekom Laboratories has spun off
its own open-source cloud-computing start-up called Zimory.
June 2009: BT moves into the Cloud
June 2009: Verizon launched its much-anticipated cloud
computing service this week, offering virtualization in a self-
service model. Verizon Computing as a Service (CaaS) will
allow users to perform all the usual cloud computing tasks:
Manage and deploy virtual servers in a Web-based user
interface, scale computing power and storage up and down, and
control private networks behind Verizon' walls.
s
November 2009: AT&T has announced AT&T Synaptic
Compute as a Service, a global cloud-based service designed to
give companies of all sizes simple on-demand access to
scalable computing capacity
