i'm looking for information on the design and implementation of replay
windows in various protocols.

what concerns drive an appropriate window size?

what role do timestamps play, if any, in constraining replay outside
the active window?

are there persistence requirements for properly maintaining a window?

what memory and processing overhead are associated with particular
moving window implementations and how can this be tuned for best

any pointers appreciated!
