Patent number: 12058097Abstract: This disclosure describes techniques for performing domain name system (DNS) support on public resolvers. For instance, an electronic device may send a query to a local DNS resolver. The electronic device may then receive an answer from the local DNS resolver that includes a pattern. Using the answer, the electronic device may generate a DNS packet that includes at least the answer and a query for a first Internet Protocol (IP) address associated with a first IP version, such as IPv6. The electronic device may then send the DNS packet to a public DNS resolver. Using the DNS packet, the public DNS resolver may generate a synthesized IP address associated with the first IP version.

Patent number: 12052148Abstract: Techniques and mechanisms for managing a set of data network nodes in a Network Management System (NMS). In some examples, a network orchestrator receives a first service request to trigger a first service transaction to re-configure the set of data nodes in the data network, and trigger, the first service transaction to re-configure the set of data nodes. In some examples, the network orchestrator receives a second service request to trigger a second service transaction to re-configure the set of data nodes. The orchestrator determines whether the second service transaction conflicts with the first service transaction that is currently running. If the second service transaction does not conflict with the first service, it triggers processing the second service. If the second service transaction does conflict with the first service transaction, it delays from processing the second service transaction.Type: GrantFiled: July 24, 2023Date of Patent: July 30, 2024Assignee: Cisco Technology, Inc.Inventors: Viktoria Fordos, Claes Daniel Nasten
