     410The architecture was revised yet again for what is hoped to be the final time. This includes:
     411 * Filter system, to intercept events and present them in a specific manner to the dispatcher
     412 * Caches, referenced by the dispatcher for cache-related filters. These are manipulated by the upstream objects when they receive results from their server halves. 
     413 * Flow entry caching - for storing results from servers. This system is "already there", as in, it is a matter of pointing things to the static flow pusher.
     414 * Current events cache - for providing an event-triggered filter with the "current" context for the event. Manipulated by server results like the device/switch caches.
     415
     416Each upstream object has a local table to map transactions to source, for proper choosing of return path.
     417
     418The logical organization of the system then looks like this:
