Abstract
Various embodiments relate to a Cloud Data Center, a system comprising the Cloud Data Center, and a related method. The Cloud Data Center may include a logical customer edge router to send packets between addresses in a private enterprise network and addresses in a logical network within a cloud network using Layer 2 protocol and MAC addressing. The logical network may have resources, known as virtual machines, allocated to the private enterprise network and may share a common IP address space with the private enterprise network. A directory at the Cloud Data Center may correlate the enterprise IP addresses of virtual machines with a MAC address, cloud IP address, and a location IP address within the logical network. The Cloud Data Center may double encapsulate packets with MAC, cloudIP, and locIP headers, when sending a packet to a destination in the logical network.
