NETWORK NODE CONNECTED TO REMOTE DISTRIBUTION CLOUD SYSTEM THROUGH PTN SYSTEM, AND DISTRIBUTION CLOUD SYSTEM INCLUDING NETWORK NODE

摘要

Embodiments of the present invention relate to connection of a cloud system and a packet transport network (PTN) system. According to an embodiment of the present invention, a distribution cloud system is connected to a remote distribution cloud system through the PTN system. The distribution cloud system comprises: a virtual network managing device which generates a tunnel mapping rule for a network packet based on address information of virtual networks in distribution cloud systems, and tunnel mapping information of a PTN tunnel formed in the PTN system; a virtual router which routes the network packet destined for a remote virtual network based on the tunnel mapping rule; and a PTN adapter which performs tunnel mapping for the network packet received from the virtual router based on the tunnel mapping rule. The present invention connects the distribution cloud systems to each other through the PTN system.;COPYRIGHT KIPO 2017
