I have read this about INT and was wondering... where is all the INT data saved?
Is it in the packet metadata? and if so, does metadata count as a part of the total packet length? I know metadata isn't a part of the packet per-se (hence the name META) but there is actual data there that needs to be sent.
Theoretically speaking there could be an infinite number of INT-capable devices between the INT-source and the INT-sink (i.e. INT-hops). Where do we save all that data?
A detailed explanation of INT in general will be appreciated also.
