Abstract
In one embodiment, a method includes receiving data at a virtual switch located at a network device in a cloud network. The data is received from an external network and destined for one or more virtual machines located in the cloud network and associated with the external network. The method further includes transmitting the data from the virtual switch to the virtual machines. The virtual switch operates as an access layer switch for the external network and creates a virtual switching overlay for secure communication between the virtual machines and the external network. Logic and an apparatus are also disclosed.
Claims20
A method comprising:
- receiving data at a virtual switch located at a network device in a cloud network, said data received from an external network and destined for one or more virtual machines located in the cloud network and associated with the external network;
- and
- transmitting said data from the virtual switch to said one or more virtual machines;
- wherein the virtual switch operates as an access layer switch for the external network and creates a virtual switching overlay for secure communication between the virtual machines and the external network.
Logic encoded in one or more tangible media for execution and when executed operable to:
- switch data between virtual machines located in a cloud network;
- forward data to an external network;
- perform access layer switch operations for the external network;
- and
- create a virtual switching overlay for secure communication of said data between the virtual machines and the external network.
An apparatus comprising
- means for receiving data at a virtual switch in a cloud network, said data received from an external network and destined for one or more virtual machines located in the cloud network and associated with the external network;
- and
- means for transmitting said data from the virtual switch to said one or more virtual machines;
- wherein the virtual switch operates as an access layer switch for the external network and creates a virtual switching overlay for secure communication between the virtual machines and the external network.
