Hi all,
Can the data plane (network devices) in SDN be understood as containing
L1 and L2 only? I am referring to pure OpenFlow devices, not hybrid ones.
No, many OpenFlow devices can parse and modify L3 (IP or MPLS) and L4
(TCP, UDP, or SCTP) headers.
If the answer is "yes", then what if applications require different MAC
or even PHY mechanisms?
OpenFlow 1.x is somewhat biased towards Ethernet; people should make
proposals to ONF if they want support for other protocols. Or maybe you
can just use OXMs.
