Key messages
Axiomatics
- How does standardized authorization mnagement support SOA in Telecom Networks (focus on use of XACML, at service and device configuration level)
- Authorization is meant as a service to other applications and services
- As well as location, IPTV … it would be important to provide also Authorization as a “telecom service”
- Operators would like to avoid micro-management of services and features of service providers (avoid micro-management)
- SPs need to control their services themselves
- Gave examples on access permissions (e.g. end user access to service) and on specific services for users (e.g. parking service… different policies)
- Issues: policy enforcement, policy administration, attribute management
- Authorization service shall be provided by Operators to SPs and XACML 3.0 can play an important role
Aepona
- Core Telco service enablers: payments, messages, presence, location --> they are assets
- SOA is about the interface for 3rd parties to access such enablers
- 3 “killer capabilities”: contextual presence, location – flexible media and conference switching – Intelligent notification services
- WS for telecom exist: Parlay-X: enphasis must be put on refining and making them popular
- Concrete examples of application of WS in Telecom (automated appointment reminder, public sector property maintenance … enhanced)
- Real web services need policy and security control – SDOs must work on this
Microsoft Mediaroom
- Brand name for IPTV solution: platform for delivery of video over (reliable) IP network
- Broad view of the End-2-End IPTV solution: content acquisition, content protection, service management, subscriber management, service delivery, service consumption
- Provided high level view o the architecture
- SOA enables highly decoupled, modular and interoperable architecture
- Understood OSS and BSS functionalities applied to the platform
Use SOAP based web services
- Loosely coupled services
Lessons learned
- Web services ala RPC increased coupling and reduced agility
- SOAP limitations (exposing/retrieving large resources and low end hardware)
- It is critical adding better control for accessing server resources
- Modeling unknown applications is hard
- Saying “contract first” is not good enough
Future needs
- Better control of workflow
- Simplify access to resources to facilitate application extensibility
- Emphasis on modeling (access profiles, layering of interfaces)
- Need standards on SLA management
