Server Architecture

We have seen, MINA based Application Architecture in previous section. Lets focus on Server Architecture. A Server listens on a port for incoming requests, process them and send replies.

  • IOAcceptor listens on the network for incoming connections/packets
  • For a new connection, a new session is created and all subsequent request from IP Address/Port combination are handled in that Session
  • All packets received for a Session, traverses the Filter Chain as specified in the diagram. Filters can be used to modify the content of packets (like converting to Objects, adding/removing information etc). For converting to/from raw bytes to High Level Objects, PacketEncoder/Decoder are particularly useful
  • Finally the packet or converted object lands in IOHandler. IOHandlers can be used to full fill business needs.
