1. Enabling Testing Scenarios - COIAS Meeting – Luis Velasco, Jose Luis Hilera TESTING SCENARIOS BT-UCL Luis Velasco, Jose Luis Hilera BT-Laboratories

2. COIAS meeting Our Proposal: Policy Driven Schemas  Use Enhanced Metadata to describe routing policies and express user preferences  differential service.  This Metadata works in a per-session basis  XML is the technology used to wrap this Metadata  allows multiple metrics...  Type of Services and Conditions required by the service can be expressed  Use Policies to Enforce QoS requirements.  LDAP to store the policies  Provide the means to share policies and populate the servers automatically
