Abstract: Example methods and systems for intent-based network virtualization design are disclosed. One example may comprise: obtaining configuration information and traffic information associated with multiple virtualized computing instances, processing the configuration information and traffic information to identify network connectivity intents and mapping the network connectivity intents to a logical network topology template. Based on a first switching intent, a first group may be assigned to a first logical network domain and the logical network topology template configured to include a first logical switching element. Based on a second switching intent, a second group may be assigned to a second logical network domain and the logical network topology template configured to include a second logical switching element. Based on a routing intent, the logical network topology template may be configured to include a logical routing element.

Abstract: Example methods and systems for a network management entity to perform topology-aware control information dissemination in a software-defined networking (SDN) environment. The method may comprise obtaining group topology information specifying a network group, and a network configuration object that references the network group. The method may also comprise: processing the group topology information to identify, from multiple members of the network group, a first member that is relevant to a first host; and processing the group topology information to identify, from the multiple members, a second member that is irrelevant to the first host. The method may further comprise: generating and sending, to the first host, control information associated with a subset of the network group. The subset may include the first member but exclude the second member.
