Abstract
Example methods are provided for a first host to perform context-aware network mapping a software-defined networking (SDN) environment. One example method may comprise: detecting multiple packet flows that include an egress packet flow originating from a first endpoint and destined for a second host, and an ingress packet flow originating from a second host or a third host and destined for the first endpoint or a second endpoint. The method may also comprise: in response to detecting the egress packet flow, obtaining first packet flow information and first context information; in response to detecting the ingress packet flow, obtaining second packet header information and second context information; and generating network map information that identifies the egress packet flow based on the first packet flow information and first context information, and the ingress packet flow based on the second packet flow information and second context information.
