Abstract: Embodiments described herein generally involve identifying workloads in a multi-site networking environment. Embodiments include determining that a given network is stretched across a first network segment at a first site and a second network segment at a second site. Embodiments include creating a stretched administrative domain for the given network and mapping an address of the given network to the stretched administrative domain in a lookup table for an administrative domain associated with the first network segment. Embodiments include receiving a flow record from an observation point in the first network segment, the flow record having a source IP address associated with the second network segment and a destination IP address associated with the first network segment. Embodiments include identifying a source workload and destination workload of the flow record using the lookup table and a workload identification table that maps combinations of IP addresses and administrative domains to workloads.

Abstract: Some embodiments provide a novel method for assessing the suitability of network links for connecting compute nodes located at different geographic sites. The method of some embodiments identifies and analyzes sample packets from a set of flows exchanged between first and second compute sites that are connected through a first network link in order to identify attributes of the sampled packets. The method also computes attributes of predicted packets between the identified samples in order to identify attributes of each flow in the set of flows. The method then uses the identified and computed attributes of each flow in the set of flows to emulate the set of flows passing between the two compute sites through the second network link in order to assess whether a second network link should be used for future flows (e.g., future flows exchanged between the first and second compute sites).
