Abstract
Embodiments of the invention relate to overlay network address management. One embodiment includes an overlay gateway including an overlay network manager associated with a physical network. The overlay network manager prevents duplicate address assignment for overlay domains having a first sharing status and performs address translation for overlay domains having a second sharing status. Address translation is avoided for overlay domains having the first sharing status.
Claims25
An overlay gateway comprising:
- an overlay network manager associated with a physical network, the overlay network manager prevents duplicate address assignment for overlay domains having a first sharing status, and performs address translation for overlay domains having a second sharing status, wherein address translation is avoided for overlay domains having the first sharing status.
An overlay network system comprising:
- a physical network;
- a network manager coupled to the physical network, the network manager creates one or more networks overlaying the physical network;
- an overlay domain administrator module that assigns a set of address spaces for each overlay domain, wherein the set of address spaces each include an address sharing status indication;
- and
- an overlay network manager that prevents duplicate address assignment for overlay domains having a first sharing status, and performs address translation for overlay domains having a second sharing status, wherein address translation is avoided for overlay domains having the first sharing status.
A method comprising:
- creating a plurality of overlay domains each associated with an underlying physical network;
- assigning a set of address spaces for each overlay domain, wherein the set of address spaces each include an address sharing status indication;
- preventing duplicate address assignment for overlay domains having a first sharing status;
- and
- performing address translation for overlay domains having a second sharing status, wherein address translation is avoided for overlay domains having the first sharing status.
A non-transitory computer-useable storage medium for managing addresses in an overlay network, the computer-useable storage medium having a computer-readable program, wherein the program upon being processed on a computer causes the computer to implement:
- creating a plurality of overlay domains associated with an underlying physical network;
- assigning a set of address spaces for each overlay domain, wherein the set of address spaces each include an address sharing status indication;
- preventing duplicate address assignment for overlay domains having a first sharing status;
- and
- performing address translation for overlay domains having a second sharing status, wherein address translation is avoided for overlay domains having the first sharing status.
