Thanks to Martin's presentation on "Towards Transport - Agnostic Middleware". I think what Martin's presented is the key value of SDN, providing the hooks and ways for Applications to control the desired services from network (transport), more than what TCP/UDP can provide.

I've been closely following and contributing to SFC, SDNrg, and have been chairing ONF's L4-L7 Service group. There has been a lot of talks on Metadata in SFC, but the metadata discussion has been mudded by information among various entities.

The  "messaging middleware Layer" is a really good way to show metadata among Middle ware boxes. There could be metadata among applications, metadata among transport layers or network layers. Then there could be metadata across layers: such as meta data from middle ware boxes to Transport layer, the meta data from applications to middleware layer, etc.

I think the work proposed by TAPS is a concrete step towards allowing applications to have better control of the network services.
