System and method for identifying communication between virtual servers

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.
