Patent number: 11533250Abstract: A method of reverse migrating traffic in a network includes receiving, via an application programming interface (API), a request to migrate traffic, the request identifying a target around which the traffic is to be migrated and a peer to which the traffic is to be migrated. The computer-implemented method further includes generating one or more masks comprising weights indicating a percentage of traffic to send to each port of at least two ports. The computer-implemented method further includes stacking the one or more masks on a base mask denoting a default configuration of a network component. The computer-implemented method further includes facilitating migration of the traffic using the one or more masks. The computer-implemented method further includes performing a reverse migration from the target to the peer by removing each of the one or more masks.Type: GrantFiled: March 2, 2021Date of Patent: December 20, 2022Assignee: AT&T Intellectual Property I, L.P.Inventors: Ajay Mahimkar, Yikai Lin, Zihui Ge

Patent number: 10958560Abstract: A method of migrating traffic in a network includes receiving, via an API, a request to migrate traffic. The request identifies a target around which the traffic is to be migrated and a peer to which the traffic is to be migrated. The method also includes discovering at least one anchor point based on at least a topology of the network, the target, and the peer. The method includes, based on an identity of the at least one anchor point and the target, identifying a migration mechanism. The method also includes requesting, in accordance with the migration mechanism, that the at least one anchor point facilitate migration of the traffic. The method includes responding, through the API, to the request indicating whether the migration was successful.Type: GrantFiled: July 16, 2019Date of Patent: March 23, 2021Assignee: AT&T Intellectual Property I, L.P.Inventors: Ajay Mahimkar, Yikai Lin, Zihui Ge
