Hi Alberto at all,
I have read your draft with high interest expecting to understand what the
"sdn" is. And you did not let me down as the draft provided clear
definition of 5-tuples to be all the SDN magic is about:
5-tuple: The term 5-tuple is used in this document to describe the
set comprised by 5 elements, being these the source IP address,
the destination IP address, the level 4 protocol number, the level
4 protocol source port and the level 4 protocol destination port
of a data packet.
Considering you implicitely meant IPv4 & IPv6 you have really defined
7 tuples ...
But I must ask why limit yourself to 5 or 7 tuples if another
standards body (at least one claims to be the SDO)
already
long time
ago defined 39 tuples to be SDN primitives or building blocks.
Is there something among those
39 tuples xTRs can't do ? I guess not as both could be same boxes
from same ODM vendor :)
List of those 39ers (src: OF 1.3
