Configuring a packet to include a virtual machine identifier
A server, includes 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 and a first packet field for a VLAN-Tag, wherein the network, interface transmits the packet to a packet encapsulate section which encapsulates a second packet field including the Layer 2 header information with a virtual network identifier representing a virtual network to which the virtual machine belongs.
1. A method, comprising:
assigning a first virtual machine identifier (VMID) to a first virtual machine operating on a first server; and
configuring a packet, in a form of a Transmission Control Protocol/Internet Protocol (TCP/IP) packet, to include a field that indicates the first VMID and a second VMID assigned to a second virtual machine operating on a second server, for the first server to use when communicating with the second server,
wherein the packet is configured to be identified by a switch, on a network connecting the first server and the second server, based on the first VMID and the second VMID in the packet.
2. The method of claim 1 , wherein the field is a virtual local area network (VLAN) tag field containing the first VMID and the second VMID, and further comprising:
inserting the VLAN tag field in the packet.
3. The method of claim 1 , wherein the field is a virtual local area network (VLAN) tag field containing the first VMID and the second VMID, and further comprising:
removing the VLAN tag field from the packet.
4. The method of claim 1 , wherein the field is at least a part of an address field in a header field of the packet, and further comprising:
converting the at least a part of the address field to the first VMID and the second VMID.
5. The method of claim 1 , further comprising:
incorporating at least one of the first VMID or the second VMID into at least one of a Media Access Control (MAC) address or an Internet Protocol (IP) address; and
assigning the at least one of the MAC address or the IP address to the first virtual machine.
6. The method of claim 1 , further comprising:
assigning a VLAN identifier (ID) to the first virtual machine as a group ID, wherein the VLAN ID is assigned to a VLAN tag field of the packet.
7. The method of claim 1 , further comprising:
determining a virtual private network (VPN) ID based on a MAC address field, an IP address field, and a VLAN tag field in the packet;
changing a destination of the packet; and
generating an encapsulated packet including the VPN ID.
8. The method of claim 1 , further comprising:
executing at least one of a hypervisor or a virtual machine monitor (VMM) to configure the packet.
9. An apparatus, comprising:
a memory; and
a processor configured to execute instructions stored in the memory to:
assign a first VMID to a first virtual machine operating on the apparatus; and
configure a packet, in a form of a TCP/IP packet, to include a field that indicates the first VMID and a second VMID assigned to a second virtual machine operating on a second apparatus, for the apparatus to use when communicating with the second apparatus,
wherein the packet is configured to be identified by a switch, on a network connecting the apparatus and the second apparatus, based on the first VMID and the second VMID in the packet.
10. The apparatus of claim 9 , wherein the field is a VLAN tag field containing the first VMID and the second VMID, and wherein the processor is further configured to execute instructions stored in the memory to:
insert the VLAN tag field in the packet.
11. The apparatus of claim 9 , wherein the field is a VLAN tag field containing the first VMID and the second VMID, and wherein the processor is further configured to execute instructions stored in the memory to:
remove the VLAN tag field from the packet.
12. The apparatus of claim 9 , wherein the field is at least a part of an address field in a header field of the packet, and wherein the processor is further configured to execute instructions stored in the memory to:
convert the at least a part of the address field to the first VMID and the second VMID.
13. The apparatus of claim 9 , wherein the processor is further configured to execute instructions stored in the memory to:
incorporate at least one of the first VMID or the second VMID into at least one of a MAC address or an IP address; and
assign the at least one of the MAC address or the IP address to the first virtual machine.
14. The apparatus of claim 9 , wherein the processor is further configured to execute instructions stored in the memory to:
assign a VLAN ID to the first virtual machine as a group ID, wherein the VLAN ID is assigned to a VLAN tag field of the packet.
15. The apparatus of claim 9 , wherein the processor is further configured to execute instructions stored in the memory to:
determine a VPN ID based on a MAC address field, an IP address field, and a VLAN tag field in the packet;
change a destination of the packet; and
generate an encapsulated packet including the VPN ID.
16. A non-transitory computer readable medium storing instructions operable to cause one or more processors to perform operations comprising:
assigning a first VMID to a first virtual machine operating on a first server; and
configuring a packet, in a form of a TCP/IP packet, to include a field that indicates the first VMID and a second VMID assigned to a second virtual machine operating on a second server, for the first server to use when communicating with the second server,
wherein the packet is configured to be identified by a switch, on a network connecting the first server and the second server, based on the first VMID and the second VMID in the packet.
17. The non-transitory computer readable medium storing instructions of claim 16 , wherein the field is a VLAN tag field containing the first VMID and the second VMID, the operations further comprising:
inserting the VLAN tag field in the packet.
18. The non-transitory computer readable medium storing instructions of claim 16 , wherein the field is a VLAN tag field containing the first VMID and the second VMID, the operations further comprising:
removing the VLAN tag field from the packet.
19. The non-transitory computer readable medium storing instructions of claim 16 , wherein the field is at least a part of an address field in a header field of the packet, the operations further comprising:
converting the at least a part of the address field to the first VMID and the second VMID.
20. The non-transitory computer readable medium storing instructions of claim 16 , the operations further comprising:
incorporating at least one of the first VMID or the second VMID into at least one of a MAC address or an IP address; and
assigning the at least one of the MAC address or the IP address to the first virtual machine.
