LAYER 2 SEAMLESS SITE EXTENSION OF ENTERPRISES IN CLOUD COMPUTING

摘要

The various embodiments relate to a system, method, and associated comprising a cloud data center, a cloud data center . Has a cloud data center may comprise a logical customer edge router to send packets between the logical address in the network address in the network in a cloud and private enterprise network using the Layer 2 protocol and MAC addressing. Logical networks may have a resource known as a virtual machine assigned to the private enterprise network, and share the private enterprise network with a common IP address space. Directory in cloud data center is able to correlate the enterprise IP address of the virtual machine in the MAC address, IP address, the cloud, and the IP address in the logical network location. Cloud data centers can be when sending a packet to a destination within a logical network using a MAC, cloudIP, and locIP double header to encapsulate the packet.
