Abstract: Disclosed is a communication control method of a container in a container environment provided from a computing apparatus, performed by a controller. The communication control method may include, when the container is newly generated, generating a flow rule for controlling a communication path of a data packet related to the container through a software switch supporting OpenFlow; generating tunnel information that includes a tunnel inner Internet protocol (IP) corresponding to the container; and transmitting the flow rule or the tunnel information to the computing apparatus.

Abstract: A communication control method performed by a controller may include receiving, from at least one of a first user terminal and a second user terminal, a network generation request for a first network that connects the first user terminal and the second user terminal, in response to the network generation request, transmitting a first network namespace generation request corresponding to at least one of the first user terminal and the second user terminal to a gateway, and when a first network namespace is generated in the gateway in response to the first network namespace generation request, transmitting information about a first virtual interface to be allocated to the first network namespace to the gateway.
