Abstract

Embodiments of the present invention relate to an approach for reconfiguring interrelationships between components of virtual computing networks (e.g., a grid computing network, a local area network (LAN), a cloud computing network, etc.). In a typical embodiment, a set of information pertaining to a set of components associated with a virtual computing network is received in a computer memory medium or the like. Based on the set of information, a graphical representation (e.g., hierarchical tree) depicting the set of interrelationships between the set of components is generated. When a failure in the virtual computing network is detected, at least one of the set of interrelationships between the set of components is reconfigured based on the graphical representation and the set of rules to address the failure.

receiving, in a computer memory medium, a set of information pertaining to the set of components associated with the virtual computing network, the set of components comprising a set of servers, a set of ports, a set of switches and a set of virtual machines (VMs), and the set of information describing a set of interrelationships between the set of components;

generating, based on the set of information, a graphical representation depicting the set of interrelationships between the set of components;

detecting a failure in the virtual computing network; and

reconfiguring, responsive to the failure, at least one of the set of interrelationships between the set of components based on the graphical representation and a set of rules.

2. The computer-implemented method of claim 1, the set of information being obtained from the set of switches, and the set of information comprising at least one of the following:

a set of routing tables, a virtual computing network configuration port mapping, or a Media Address Control (MAC) address to a set of Internet Protocol (IP) tables.

3. The computer-implemented method of claim 2, the set of information being further obtained from the set of servers, and the set of information further comprising at least one of the following:

a set of mappings between the set of VMs and the set of switches, a set of mappings between the set switches and the set of ports, or a set of mappings interbetween the set of ports.

4. The computer-implemented method of claim 1, the virtual computing network comprising a virtual local area network (VLAN), and the set of ports comprising at least one virtual port and at least one physical port.

5. The computer-implemented method of claim 1, the graphical representation comprising a hierarchical tree comprising a set of nodes corresponding to the set of components.

6. The computer-implemented method of claim 1, the set of rules comprising an ordered set of criteria for determining which interrelationships between the set of components to reconfigure so that the set of components remains accessible despite the failure.

7. The computer-implemented method of claim 1, the failure comprising a failure of a communication link between at least two of the set of components.

8. A system for reconfiguring interrelationships between a set of components of a virtual computing network, comprising:
