Background

Overall Process Model

Scenarios

http://services.future-internet.eu/index.php/FISO_Scenarios

Scenario 1

Service procurement

1. Users specify requirements for a service

2. Functional and non-functional requirements included

3. Semantic search engine able to find relevant services

4. User selects relevant service

5. User fills in an SLA template

6. SLA given to provider

7. After Authentication and Authorization Performance monitoring is carried out

What If Questions (1/2)1. What if standard representations of SLAs,

and standard protocols for their negotiation and monitoring or uniform descriptions for services of different types are not taken up by a large community?

2. What if many devices/channels do exist, on which the services will be created or consumed (mobile devices, television, telephone, washing machine, refrigerator, printer, sensors) are sometimes switched off?

3. What if consumers are not able to generate their requirements?

What If Questions (2/2)4. What if consumers are not able to select

services?

5. What if providers cannot fill in the SLA templates of their services?

6. What if it is not possible to find SLA descriptions of complex composed services across providers? Especially if compositions are generated on-the-fly?

7. What if several industries provide services in incompatible ways.

8. What if there are many internets?

Research Challenges(1) What if standard representations of SLAs,

and standard protocols for their negotiation and monitoring or uniform descriptions for services of different types are not taken up by a large community?

Develop and apply different SLA representations (potential standards) at large scale

How do we combine heterogeneous SLA representations

(3) What if consumers are not able to generate their requirements?

Easy end-user generation of requirements. Semi-automated generation.

Opportunities for FIRE Facilities Use

Test interoperability between IT, Telco and Media services

Test performance of different SLA representations

Scenario 2

Service Lifecycle

As determined by the Telemanagement Forum

1. Develop a service (service developer)

2. Determine resource requirements (service developer)

3. Develop SLA templates (service provider)

4. Advertise service (service provider)

5. Negotiation and sales (customer) 

6. Assessment (service provider)

7. Decommission service (service provider)

What If Questions (1/2)1. What if the lifetime of value for services-

based content exists for 5 minutes or 50 years?

2. What if the lifetime of all types of service-based assets (content, things, networks, etc) outlives the lifetime of the service?

3. What if the SLA template lifecycle is a process of collaborative decision making?

4. What if application and resource lifecycle is developed independently of the service lifecycle?

5. What if lifecycle of customer and community interests transition faster than service development activities?

What If Questions (2/2)

6. What if “too much” adaptability is offered by service providers in SLA templates and APIs?

7. What if customers want to know risks in networks of services offered by their providers?

8. What if customers need predictions on when an SLA may be breached?

9. What if services need to be developed by non-IT experts?

Research Challenges(3) What if the SLA template lifecycle is a

process of collaborative decision making?

Supporting collaborative SLA development across organisational boundaries and incorporating multiple viewpoints

(5) What if lifecycle of customer and community interests transition faster than service development activities?

Consumer communities to be more involved in the ‘development’ process – to move towards a prosumer role

Fulfilling dynamically changing business objectives which may not be known at design time

Scenario 3

Wedding Scenario

What if Questions and Research Challenges

What if discovery is not able to access the context?

Discovery based on on functionality, location, access range, pricing and feedback

What if the feedback is not trusted?

Incorporating trust mechanisms into feedback

Scenario 4 Due in one week
