    • A capability is provided for providing transparent cloud computing with a virtualized network infrastructure. A method for enabling use of a resource of a data center as an extension of a customer network includes receiving, at a forwarding element (FE), a packet intended for a virtual machine hosted at an edge domain of the data center, determining a VLAN ID of the VLAN for the customer network in the edge domain, updating the packet to include the VLAN ID of the VLAN for the customer network in the edge domain, and propagating the updated packet from the FE toward virtual machine. The edge domain supports a plurality of VLANs for a respective plurality of customer networks. The packet includes an identifier of the customer network and a MAC address of the virtual machine. The VLAN ID of the VLAN for the customer network in the edge domain is determined using the identifier of the customer network and the MAC address of the virtual machine. The FE may be associated with the edge domain at which the virtual machine is hosted, an edge domain of the data center that is different than the edge domain at which the virtual machine is hosted, or the customer network. Depending on the location of the FE at which the packet is received, additional processing may be provided as needed.
    • 提供了一种提供透明云计算与虚拟化网络基础架构的能力。 用于使数据中心的资源能够用作客户网络的扩展的方法包括在转发元件(FE)处接收旨在用于驻留在数据中心的边缘域的虚拟机的分组,确定VLAN 边缘域中客户网络的VLAN ID,更新报文,包括边缘域中客户网络的VLAN的VLAN ID,并将更新的报文从FE传播到虚拟机。 边缘域为相应的多个客户网络支持多个VLAN。 该分组包括客户网络的标识符和虚拟机的MAC地址。 边缘域中客户网络的VLAN的VLAN ID使用客户网络的标识符和虚拟机的MAC地址来确定。 FE可以与托管虚拟机的边缘域,数据中心的边缘域与虚拟机所在的边缘域或客户网络相关联。 根据接收到分组的FE的位置,可以根据需要提供额外的处理。
