  1. TESTING SCENARIOS BT-UCL Luis Velasco, Jose Luis Hilera BT-Laboratories

  2. 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
