Virtualized network for virtualized guests as an independent overlay over a physical network

摘要

A method for operating a virtualized network that communicatively connects between a plurality of communication ports, instantiated for a plurality of guest operating systems executed over a plurality of hosts. The method comprises instantiating a communication port for each of the plurality of guests; performing a discovery media access control (MAC) address process of at least one destination guest of the plurality of guests by a source guest; sending a ping request from the source request to the at least one destination guest; and creating the virtualized network to allow communication between the source guest with the at least one destination guest, wherein the virtualized network is created over the physical network.

主权项

1. A system for enabling effective communicating over cloud-based infrastructures, comprising:
a first host operative in a first cloud-based infrastructure, wherein the first host executes a first guest operating system; a first communication port instantiated for the first guest; a second host operative in a second cloud-based infrastructure, wherein the second host executes a first guest operating system, wherein each of the first host and the second host include at least a network interface card (NIC); and a second communication port instantiated for the second guest, wherein the first guest operating system is configured to discover an identifier of the second communication port of the second guest operating system using an address discovery protocol; wherein the first host and second host are communicatively connected through a physical network, wherein the first communication port and the second communication port are communicatively connected to constitute a distributed communication element that enables a virtualized network for communication between the first guest and the second guest via the first communication port and the second communication port respectively, wherein the control logic of the distributed communication element is distributed to each of the first and second communication ports of the respective first host and second host to execute a respective portion of the switching functionality of the distributed communication element in a distributed manner independently of each other.
