Claim 10:
11. A non-transitory machine readable medium storing a program for assessing changes to physical network links used to connect different compute sites, the program for execution by at least one processing unit of a computer, the program comprising sets of instructions for:
using a packet sampler to identify sample packets from packets exchanged between first and second compute sites connected through a first physical network link as part of a set of flows exchanged between the first and second compute sites, wherein the sample packets are a subset of all of the packets of the set of flows;
analyzing the sample packets to identify attributes of the sample packets;
identifying a plurality of predicted packets that are each predicted to be between two identified sample packets in a flow in the set of flows;
computing attributes of the predicted packets in order to identify attributes of each flow in the set of flows; and
using the identified and computed attributes of each flow in the set of flows to perform an emulation of the set of flows being exchanged between the first and second compute sites through a second physical network link in order to assess whether the second physical network link should be used for future flows.
