Abstract: The disclosure provides an approach for computing service paths for a service chain identifying a sequence of services. One method includes including information about a plurality of hosts in a heap. Each of the plurality of hosts includes at least one service virtual computing instance (SVCI) configured to provide at least one of the services of the service chain. The information includes, for each of the plurality of hosts, a number of service paths computed for the service chain at the host and one of a number of services provided by unused SVCIs of the host or a number of consecutive services provided by unused SVCIs of the host. The method further includes selecting a host from the heap based on the information. The method further includes generating a first service path for the service chain, the first service path identifying at least one SVCI of the selected host.

Abstract: A method of recording layer-2 (L2) mappings created for workloads executing on a plurality of hosts in a first database managed by a network management server: upon receipt of a first mapping reported by a first host, determining that the first mapping is not recorded in the first database; and in response to the determining that the received first mapping is not recorded in the first database, generating a first timestamp and persisting a first record in the first database that includes the first mapping and the first timestamp.
