System and method for identifying communication between virtual servers

摘要

Under the environment that IP addresses of virtual machines overlap, it makes it possible to carry out a communication between the virtual machines and for a network manager to grasp in a communication flow condition in real time. Specifically, the physical server assigns a virtual machine ID to the virtual server under the management, and assigns a reception-side virtual machine ID and a transmission-side virtual machine ID to a bit space of a transmission packet in the form of TCP/IP packet, when a communicating between the virtual servers through a network. Then, the physical server transmits the transmission packet onto the network. A physical switch is provided on the network connecting between the physical servers, and identifies the transmission packet based on the virtual machine ID contained in a bit space other than data of the transmission packet under the environment that IP addresses of the virtual machines overlap on the network, and collects data showing a network condition.

主权项

1. An inter-virtual-server communication identifying system comprising:
a reception-side physical server configured to assign a reception-side virtual machine ID (identifier) to a reception-side virtual server; a transmission-side physical server configured to assign a transmission-side virtual machine ID to a transmission-side virtual server, assign the reception-side virtual machine ID and the transmission-side virtual machine ID to at least a part of a bit space of a field other than a data field of a transmission packet in a form of a TCP/IP (Transmission Control Protocol/Internet Protocol) packet, when generating the transmission packet from said transmission-side virtual server to said reception-side virtual server, and transmit the transmission packet; and a physical switch provided on a network connecting said transmission-side physical server and said reception-side physical server, and configured to identify the transmission packet based on the reception-side virtual machine ID and the transmission-side virtual machine ID which are contained in the bit space, when relaying the transmission packet between said transmission-side physical server and said reception-side physical server, and collect data indicating a network condition.
