1. Start with standards-based IT platform (J2EE) and make it Carrier Grade

2. Extend beyond HTTP to SIP, Diameter, Parlay, IN, …

4. IT/SOA to provide revenue generating services: IT skills very rapid and agile deployment:

6. SDF/ AIA for Comms: SOA based integration of OSS/BSS/SDP : Following TMF SDF

3. Provide converged ASes (SIP, HTTP, OSA, …) and Enablers as SOA reusable components that abstract network resources + standard Northbound interfaces ; Following OSE

SDP, SDF (AIA) + Pragmatic IMS

Core in-domain services, 3rd party (SOA) services and Web 2.0 Mash-ups on a same SDP Core Services:

Developed in SDP container against enabler APIs Long tail services:

customization and usage is driven by loose composition and users: Web 2.0 using widgets and 3rd party applications built on SDP

Plethora of short lived applications to try/deploy, update and retire easily / rapidly. Innovation comes from wide community of developers => Third party services provided by third party as SOA services against enablers APIs (WS/SOA)

Sales Revenue

Services

Trusted Applications in SDP Container requiring high performances and “permissions”

3rd party applications requiring lower level of permissions and capabilities

Mashup of widgets built on SDP by third party with Web 2.0 applications

New services and SOA Any “internet service” is a Telco service possible specialized

/ robustized (carrier grade) for network or simply expose on network

Services can be SOA-based or web 2.0 based Includes customization / built by subscribers

Service are provided by internet service providers or IT developers, less and less by Telco service providers or Telco specialized vendors

Service can be built / customized / integrated by users (e.g. web 2.0 mash-ups)

Advertisement based services (a la internet) + adapted to communications (e.g. ad subsidized communications)

Services specialized for users

Need to be able to target many services offered by widest community (e.g. Internet):

IT / Internet friendly, open and standard mainstream approaches and technology:

• Capture economies of scales• Tap the widest pool of developers and entrepreneurs as developers or

Partners

Need to efficiently and rapidly develop , deploy services, validate, extract revenue and update or retire them:

Rely on common service (i.e. software) development practices Automate with open, standard and customizable ways all business

processes within the service providers an d with partners Need to Provide services in future proof manner over as many

network technologies as possible Need to be Carrier grade!

Requirements

Agenda Today’s industry situatioon Positioning SOA in SP domain



Technology challenges with SOA If we defined Carrier Grade (CG) as:

High Availability Predictable low latencies Efficient (e.g. throughput per CPU) / Economically viable Scalable Hot upgradable

MW containers can be carrier grade today SOA CG has some challenges. E.g. (non exhaustive):

Delays, predictable latencies, time to instantiate Throughput QoS, SLA enforcement LC Management like manageability of composed services and web 2.0

mash-ups (see TMF SDF) Dependencies modeling

Distributed SOA and impact on instance selection, catalogs etc… Adoption / endorsement by Telco SP and NEMs




Conclusions: Technology trends Commoditization of core MW CG SOA and web 2.0 CG SOA based Policies consolidated across whole service provider

domain (including network) Service level SCIM and SOA for complex orchestration of services

while simple orchestration may be lower in network Automated business processes CG SOA can implement core Telco services (e.g. even call control

functions) CG SOA may be achievable as SOA + distributed caching / grid

computing Product based services - end to end

“Telco in box except NW” with OSS/BSS/SDP/services SOA integration and SOA business processes extended to market places and web 2.0
