Dear Experts ,
Could you please help me with a right design choice for the following scenario. *Use case * : 1000's of Network device are controlled by a network . - Network devices will join and leave the network by sending *Join* and *Leave* messages respectively to the network controller. *Joining scenario* - When controller get a *Join* message from a network device , - it will check whether an FSM actor exists for that network device by calling getContext().getChild("networkdevice_IP"). - "networkdevice_IP" is used to identify the actor. - if the child lookup returns null , a new FSMActor will be spawned and join message is processed by the new FSMActor *Leaving scenario* - Network device will send a *Leave* message to the controller - controller will do getContext().getChild("networkdevice_IP") and get the right FSMActor. - sends “*leave* message" to this actor. - While processing Leave message , FSM actor will terminate itself by calling stop() . *Complication* - Now there is a possibility that while the stop() is being processed by FSMActor , a new Join may come from same network device (networkdevice_IP). - Since stop() is asynchronous getContext().getChild(network device) will still return the FSMActor (networkdevice_IP) , but if we send message to this actor , the message will go to DeadMessages. - *Design question .* - How to handle such scenario using AKKA ? So that we will not return a stale Actor using getContext().getChild() - [one possiblity might be to leave this corner scenario and let the network protocol to handle this with retransmission .But if retransmission is not there what to do ?] With thanks and regards Mahesh -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
