C# Class CrossroadsIO.Devices.QueueDevice

A shared queue that collects requests from a set of clients and distributes these fairly among a set of services.
Requests are fair-queued from frontend connections and load-balanced between backend connections. Replies automatically return to the client that made the original request. This device is part of the request-reply pattern. The frontend speaks to clients and the backend speaks to services.
