The distributed middleware: interconnected servers

isapiens@home server Virtual Objects Container • Exposes VOs functionality to agents • Manages VOs (registration and cancellation) • Allows to registers and subscribe rules on VOs’ resources Agent Server • Is the container for the agents • Manages agents’ life -cycle • Manages timed/untimed messages • Offers a «Yellow Pages» services through the “directory” agent

isapiens@home agents: the thread model Agent thread-less with internal- thread - Lightweight - Scalability issues arise -Concurrency issues arise -No concurrency issues

isapiens@home agents: class hierarchy agents.AgentCore (abstract) agents.Agent (abstract) agents.AgenteThreadSafe (abstract)

isapiens@home agents: the AgentCore class

isapiens@home agents: the Agent class <agente,agente,ruolo> di sistema

isapiens@home agents: the AgentThreadSafe class

The « Yellow Pages » agent Offers the following services: • advertisement (registration) • searching • facilities for sending messages to registered agents Services are based on: Roles and Properties (key,value) Services are offered by the “directory” agent The class of the «yellow pages» agent is AgentDirectory

The « Yellow Pages » agent: message interface and API

isapiens@home: deploying applications Server Server Server • Agent Server Server • VOContainer Server Deployer Deployer • Configuration purposes

Deployer Configures an application by sending on target servers: • Agents • VOBuilders (build VO on target servers) • Messages Its execution terminates when the deployment completes Deployment is achieved by using the DeplyingT ool class Deployer
