VoIP impacts... on Software Engineering

18

Impacto da Voz Sobre IP (VoIP)

Orgânicos - a introdução da Voz Sobre IP (VoIP) ao nível, por exemplo, de uma empresa implica

infrastructure merging IT, data/text and web

Aplicacional - a VoIP proporciona novos desafios nas seguintes áreas:

Tecnologias de Comunicação (CT- Communications Technologies)Tecnologias de Informação (IT - Information Technologies) puras.

Exemplo: no domínio da Convergência da telefonia Móvel versus Fixo, fala-se já da possibilidade de aplicaçao dos conceitos de "GRID computing" às infraestruturas de VoIP.

19

Organizational Impacts:Many Networks Become One

Previously we had vertical solutions that offered one network per service:

PSTN, X.25, Frame Relay, IP, Telex...

The Internet is becoming the common carrier for all services

Growth comes as various wireless access technologies connected to the Internet

Wi-Fi, 3G (data), WiMax, UWB…

20

Aplicational Impacts: Phones are Becoming Computers (1)

Powerful CPUs

Connected to the Internet via various radio networks (multi-band)

Open OS (Linux, Symbian, Windows Mobile, etc)

Easy to install applications

Affordable

21

Aplicational Impacts:Telephony is Becoming an App (2)

An application that you run on a computer

Computers have different form factorsDesktopsLaptopsPDAsMobile phonesEmbedded Increasingly ubiquitous and everywhere

22

CT - Communications Technologies

1. Presence and availibility managementpresence server, user agent, watcher, listener, buddy lists;

2. Single sign-ongeneric and single user controlled authentication

3. Plug & play Network AwarenessPeer DiscoveryApplication/Service AwarenessService discovery

4. Peer-to-PeerApplications, Client Technology, Home & Enterprise Networking

5. Total ConversationSpeech recognition and Automatic language translation

6. IMS (Fixed Mobile Convergence)

23

IT - Information Technologies

1. TELCO Resilient/highly reliable platformsReliability, redundancy, fault tolerance

2. Component TechnologiesSOA - Service Oriented ArchitecturesDistributed application processing, Application Software and TMN, e.g. Web ServicesEJB, .NET, Corba 3.0; J2EE, DCOM, SOAP, OSS/J

3. Middleware Hide platform SW (OS) and HW from applications

4. Distributed databases / storageA must for geographical redundancy and disaster recovery

5. Service Development & Deployment KitsFor in-house and 3rd party developers

6. Test automation / managementA must

24

IT - Information Technologies Challenges

1. Software Development ProcessesAgile vs eXtreme

2. GRID computingScalability, load sharing, distributed storage

3. Multi-core processorsProgramming, reliability, redundancy

4. Component TechnologiesWhich Middleware

5. Virtual Machine MonitorsServiceability

It’s a balancing actItIt’’s a balancing acts a balancing act

IMS builds Intelligence environment for agile services, though it is a ‘disruption’ - of the 3rd kind

It requires close encounter between IT and Telecom worlds

Application innovation is yet to peak, inspired by the smart endpoint, but splitting and splicing features must be addressed carefully

IMS enables sharing resources but vendors will find it hard to move from Silos to Layered approach

The wide variety of applications will necessitate integration, streamlining management and user interfaces

Our obstacle is complexity: Dealing with it is the single most important challenge facing the I/T and TELCO industries!

In Conclusion
