This graphic consists of a square turned at an angle so that appears as a diamond (point rather than edge on top). There are four labels outside the diamond:
North label- Service Creation
East label - Subscriber Personalization & Protection
South label- Network Protection
West label - Integration and Automation
The diamond itself is divided into four smaller diamonds shaded in different colors and labeled as follows:
North diamond - Application Service Creation Tools /High level Web Service APIs
East diamond - Subscriber Profile Access
South diamond - WS-Security / SLA Policy Enforcement / Traffic throttling & shaping
West diamond - Partner Management Interfaces / Billing and OSS Integration
Superimposed on the center on the diamond where they smaller diamonds meet is a rectangle labeled Services Gatekeeper.
