I am writing an application that interprets a time delayed stream of data. The data arrives at consistent intervals, and each data packet consists of 3 primitive values.

I need to process this stream to calculate a value every time a new packet arrives.
The calculation includes the need to include ‘look-back’ values, hence it may only produce an output value after a given number of packets have arrived.
The types of functions I apply to the buffered data include, SD, MEAN(OVER RANGE), MAX/MIN etc, all basic statistical functions.

I have coded this using buffers, but I am thinking – what I am basically building is a fixed function pipeline… this must have been done before in .net…

Is there some library that I can use to ‘fluently’ (preferably) construct my function pipeline, and then simply pump packets into it, and read out the various results that are generated?

Thanks

    It sounds like Reactive Extensions (Rx) may be what you are looking for. Rx allows you to apply Linq (i.e. a “fluent” API) to a stream of data. It also allows you to define the length of your buffer if you for example wish to calculate a running average over a window of the latest 100 observations (what you call “look-back” values).

    There are a couple of videos on Channel9 to get you started. This one shows how to do calculations based on “look-back” values.
