Appl. No.:

11/434626

Inventors:

Shih-Chung Tom Soon - Dublin CA, US
Yongdong Zhao - Pleasanton CA, US
Teong Yee Tan - Fremont CA, US

Bei Zhou - Union City CA, US

Assignee:

AT&T Intellectual Property I, L.P. - Atlanta GA

International Classification:

G01R 31/08

US Classification:

370225

Abstract:

A system and method for routing data, the system having a processor, an interface in communication with the processor and capable of being in communication with a second system for routing data, a memory unit in communication with the processor, the memory unit having a network routing table having a plurality of routes, the plurality of routes having a first route; and a network failure route selection logic including instructions adapted to configure the processor to determine when the first route is inoperative, transmit a first data packet to the second system for routing data when the first route is inoperative and utilize a second route selected from one of the plurality of routes, the second route being different from the first route.

International Classification:

H04L 12/28

US Classification:

370254, 370223, 370230, 370234, 370401

Abstract:

Systems and methods of automatically determining a set of route targets is provided. The method includes receiving network topology data specifying configuration of a network. The method also includes automatically converting the network topology data into route targets to be assigned to virtual routing and forwarding elements. The route targets are grouped into sets and duplicate sets of route targets are removed based on the route targets between duplicate sets of route targets identified as being the same. The method further includes generating a data record including information related to the set of route targets.

International Classification:

H04J 1/16
H04L 12/28

US Classification:

370252000, 370254000, 370395500

Abstract:

The disclosed method and system provides a new service provision interface that allows operator use without requiring many of the specific technical network details, such as VRF, RT, SOO, route redistribution, etc. Further, the translation from a customer's requirements (including both VPN topology membership requirement and L2, L3 requirement from customer) into technical network configuration commands are handled using an automated method that is transparent to the operator. In a particular illustrative embodiment of this patent disclosure, a high level table with reduced technical detail is generated by an operator and an automated provisioning system, without operator visibility or required operator interaction, creates intermediate data including network specific technical information in an automated process to generate a deployable network topology including VRF and RT assignments for use in network provisioning.
