  2. Objectives • Implementation of Dynamic Classification in Silicon-Based Forwarding • Perform policy based classification and modification of packets • Specify interfaces for Java applications to control a generic, platform-neutral forwarding plane • Enable dynamic downloading of services to network devices • Provide for inter-service communication including the sharing of objects and calls into other services

  3. Accomplishments • JVM on a silicon-based Routing Switch • ORE - Oplet Run-time Environment • Java-enabled Device Architecture • Java SNMP MIB API • include proxy mode for devices with no JVM • Implementation of Network Forwarding API • All of this enables implementation of Dynamic Classification in Silicon-Based Forwarding
