Abstract:
Example methods are provided for packet handling during service virtualized computing instance migration in a software-defined networking (SDN) environment. The method may comprise configuring first reachability information to associate a first service virtualized computing instance with an active role, and second reachability information to associate a second service virtualized computing instance with a standby role. In response to determination that a switchover is required to facilitate a migration of the first service virtualized computing instance, the first reachability information may be updated to associate the first service virtualized computing instance with the standby role, and the second reachability information to associate the second service virtualized computing instance with the active role. The method may also comprise: in response to detecting a completion of the migration, updating the first reachability information to associate the first service virtualized computing instance with a target host instead of a source host.

Claim (Index 8):
A non-transitory computer-readable storage medium that includes a set of instructions which, in response to execution by a processor of a computer system, cause the processor to perform a method of packet handling during service virtualized computing instance migration in a software-defined networking (SDN) environment that includes a source host and a target host, wherein the method comprises:\n configuring first reachability information to associate a first service virtualized computing instance with an active role and the source host supporting the first service virtualized computing instance; configuring second reachability information to associate a second service virtualized computing instance with a standby role, wherein both the first service virtualized computing instance and second service virtualized computing instance are configured to provide a service; in response to determining that a switchover is required to facilitate a migration of the first service virtualized computing instance from the source host to the target host and prior to the migration, updating the first reachability information to associate the first service virtualized computing instance with the standby role, and second reachability information to associate the second service virtualized computing instance with the active role; based on the updated second reachability information, forwarding a packet that requires the service to the second service virtualized computing instance; and in response to detecting a completion of the migration, updating the first reachability information to associate the first service virtualized computing instance with the target host instead of the source host.
