Abstract
A method of operating an optical network is described. The network includes a number of nodes connected by a number of links. A method according to the present invention provisions a virtual path between a first and a second one of the plurality of nodes by: identifying the first and the second nodes, discovering a physical path from the first node to the second node, and establishing the virtual path. The method discovers a physical path from the first node to the second node by automatically identifying nodes forming the physical path. The method establishes the virtual path by configuring a set of connections between the nodes forming the physical path.

14. A method comprising:
restoring a virtual path between a first node of an optical network and a second node of said optical network, comprising discovering an alternate physical path between said first node and said second node by automatically identifying nodes of said alternate physical path, wherein said optical network comprises a plurality of nodes coupled by a plurality of optical links, said nodes comprise said nodes of said alternate physical path, and said virtual path is provisioned on a physical path between said first and said second node; and
re-establishing said virtual path by configuring a set of connections between said nodes of said alternate physical path. - View Dependent Claims (17, 18, 19, 20, 21, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. A computer program product comprising:
-
a first set of instructions, executable on a computer system, configured to restore a virtual path between a first node of an optical network and a second node of said optical network, said first set of instructions comprising a first subset of instructions, executable on said computer system, configured to discover an alternate physical path between said first node and said second node by virtue of being configured to automatically identify nodes of said alternate physical path, wherein said optical network comprises a plurality of nodes coupled by a plurality of optical links, said nodes comprise said nodes of said alternate physical path, and said virtual path is provisioned on a physical path between said first and said second node; and
a second subset of instructions, executable on said computer system, configured to re-establish said virtual path by virtue of being configured to configure a set of connections between said nodes of said alternate physical path; and
computer readable media, wherein said computer program product is encoded in said computer readable media. - View Dependent Claims (50, 51, 52, 53, 54, 55)

56. An apparatus comprising:
means for restoring a virtual path between a first node of an optical network and a second node of said optical network, comprising means for discovering an alternate physical path between said first node and said second node by automatically identifying nodes of said alternate physical path, wherein said optical network comprises a plurality of nodes coupled by a plurality of optical links, said nodes comprise said nodes of said alternate physical path, and said virtual path is provisioned on a physical path between said first and said second node; and
means for re-establishing said virtual path by configuring a set of connections between said nodes of said alternate physical path. - View Dependent Claims (57, 58, 59, 60)
