Packet handling based on virtual network configuration information in software-defined networking (sdn) environments

A non-transitory computer-readable storage medium that includes a set of instructions which, in response to execution by a processor of a first host, cause the processor to perform a method of packet handling based on virtual network configuration information in a software-defined networking (SDN) environment that includes the first host and a second host, wherein the method comprises:

• obtaining virtual network configuration information that specifies a first virtual object identifier (ID) and a first address associated with a first virtualized computing instance supported by the first host, and a second virtual object ID and a second address associated with a second virtualized computing instance supported by the second host;
• and
• in response to detecting, from the first virtualized computing instance, an egress packet with an inner header that is addressed from the first address to the second address specified in the virtual network configuration information,
• generating an encapsulated packet by encapsulating the egress packet with an outer header that specifies the second virtual object ID;
• and
• sending the encapsulated packet to the second host to cause the second host to decapsulate the outer header and, based on the second virtual object ID in the outer header, send the egress packet to the second virtualized computing instance.

A host, being a first host, configured to perform packet handling based on virtual network configuration information in a software-defined networking (SDN) environment that includes the first host and a second host, wherein the host comprises:

• a processor;
• and
• a non-transitory computer-readable medium having stored thereon instructions that, when executed by the processor, cause the processor to:
• obtain virtual network configuration information that specifies a first virtual object identifier (ID) and a first address associated with a first virtualized computing instance supported by the first host, and a second virtual object ID and a second address associated with a second virtualized computing instance supported by the second host;
• and
• in response to detecting, from the first virtualized computing instance, an egress packet with an inner header that is addressed from the first address to the second address specified in the virtual network configuration information,
• generate an encapsulated packet by encapsulating the egress packet with an outer header that specifies the second virtual object ID;
• and
• send the encapsulated packet to the second host to cause the second host to decapsulate the outer header and, based on the second virtual object ID in the outer header, send the egress packet to the second virtualized computing instance.
