NORM from the Naval Research Labs is another implementation of the same concept.

Aeron is another awesome project from Martin Thompson (Disruptor, Simple Binary Encoding, Mechanical Sympathy, etc.).

That guy really knows his stuff regarding performance.

Sounds like PGM

Similar ideas, yes. But somehow I found Aeron and got it to work, not so straightforward with PGM. Been a while now, so not sure about the details.
