Abstract

A server, including a virtual machine identifier assigning section to assign an identifier of a virtual machine operating on the server; and a network interface to transmit a packet including a Layer 2 header information which includes the identifier of the virtual machine, wherein the network interface transmits the packet to a packet encapsulate section which encapsulates a packet field including the Layer 2 header information with a virtual network identifier, wherein the virtual network identifier represents a virtual tenant network corresponding to the virtual machine in multiple tenants network.

First claim

The invention claimed is:

1. A server, comprising:
a memory storing instructions; and
a processor configured to execute the instructions to:
assign an identifier of a virtual machine operating on the server; and
transmit a packet to a network device, the packet including a Layer 2 header information which includes the identifier of the virtual machine,
wherein the network device encapsulates the packet, to generate a packet field including the Layer 2 header information, with a virtual network identifier, and
wherein the virtual network identifier represents a virtual tenant network corresponding to the virtual machine in a multi-tenant network.

2. The server according to claim 1 , wherein the processor is further configured to execute the instructions to:
receive the packet; and
remove the virtual network identifier from the packet.

3. A system, comprising:
a network device; and
a server, comprising:
a memory storing instructions; and
a processor configured to execute the instructions to:
assign an identifier of the virtual machine operating on the server; and
transmit a packet to the network device, the packet including a Layer 2 header information which includes the identifier of the virtual machine,

wherein the the network device is configured to encapsulate the packet, to generate a packet field including the Layer 2 header information, with a virtual network identifier, and
wherein the virtual network identifier represents the virtual tenant network corresponding to the virtual machine in multiple tenants network.

4. The system according to claim 3 , wherein the processor is further configured to execute the instructions to:
receive the packet; and
remove the virtual network identifier from the packet.

5. The system according to claim 3 , wherein the network device is further configured to:
forward the packet to the virtual machine based on the virtual network identifier.

6. A method, comprising:
assigning an identifier of a virtual machine operating on a server;
transmitting a packet including a Layer 2 header information which includes the identifier of the virtual machine; and
encapsulating the packet, to generate a packet field including the Layer 2 header information, with a virtual network identifier,
wherein the virtual network identifier represents a virtual tenant network corresponding to the virtual machine in a multi-tenant network.

7. The method according to claim 6 , further comprising:
receiving the packet; and
removing the virtual network identifier from the packet.

8. The method according to claim 6 , further comprising:
forwarding the packet to the virtual machine based on the virtual network identifier.

9. A network device, comprising:
a memory storing instructions; and
a processor configured to execute the instructions to:
receive a packet including a Layer 2 header information which includes an identifier of a virtual machine operating on a server; and
encapsulate the packet, to generate a packet field including the Layer 2 header information, with a virtual network identifier,
wherein the virtual network identifier represents a virtual tenant network corresponding to the virtual machine in a multi-tenant network.

10. The network device according to claim 9 , wherein the processor is further configured to execute the instructions to:
to forward the packet to the virtual machine based on the virtual network identifier.

11. A method, comprising:
receiving a packet including a Layer 2 header information which includes an identifier of a virtual machine operating on a server; and
encapsulating the packet, to generate a packet field including the Layer 2 header information, with a virtual network identifier,
wherein the virtual network identifier represents a virtual tenant network corresponding to the virtual machine in a multi-tenant network.

12. The method according to claim 11 , further comprising:
forwarding the packet to the virtual machine based on the virtual network identifier.
