Abstract:
To send data packets from one host to another in traditional local
area networks, one needs to know the MAC of destination host. This
is called the address resolution and is handled by the ARP (Address
Resolution Protocol) protocol. However the ARP Request and ARP
Response mechanism in Software-Defined Networking (SDN) (RFC7149) is
different from that in traditional local area networks. In SDN, when
there are no flow registrations in switches to forward ARP packets,
ARP packets have to be sent to the controller first. As resolving
the ARP packets may be time consuming depending on the load on the
controller and may potentially have different implications on address
resolution in SDN, characterization of this delay performance can
thus help users to know the approximate delay before the actual data
forwarding process. In this document, we define performance
parameters to characterize the delay metrics of address resolution in
SDN.
