  • Patent number: 12238079
    Abstract: A Software-Defined Networking (SDN)-based “upstream” approach is a controller-based solution that provides secure key distribution and management for multi-site data centers. The approach uses an SDN Multi-Site Controller (MSC) that acts as an intermediary between SDN controllers at sites in a multi-site data center and manages the distribution of keys to sites. The approach is not dependent upon any particular routing protocol, such as the Border Gateway Protocol (BGP), and is well suited for multicast stream encryption by allowing the same key to be used for all replicated packets sent to downstream sites from an upstream source site. The approach distributes keys in a secure manner, ensures that data transferred between sites is done in a secure manner, and supports re-keying with error handling.

  • Patent number: 12216556
    Abstract: This disclosure describes techniques for adaptive disaster recovery of applications running on network devices. The techniques include generating an application template and an application template clone that include application attributes usable to deploy an application stack at an application site. The techniques also include sending the application template clone to a disaster recovery site group to await deployment instructions. In some examples, an observer may determine that a health metric of the application site indicates that a disaster recovery process be triggered. A disaster recovery site of the disaster recovery site group may be selected based at least in part on a performance metric. The application stack may be deployed at the disaster recovery site utilizing the application template clone.

  • Patent number: 12063169
    Abstract: Embodiments herein describe using translation mappings and security contracts to establish interconnects and policies between switching fabrics at different sites to create a unified fabric. In one embodiment, a multi-site controller can stretch endpoint groups (EPGs) between the sites so that a host or application in a first site can communicate with a host or application in a second site which is assigned to the same stretched EPG, despite the two sites have different namespaces. Further, the shadow EPGs can be formed to facilitate security contracts between EPGs in different sites. Each site can store namespace translation mapping that enable the site to convert namespace information in packets received from a different site into its own namespace values. As a result, independent bridging and routing segments in the various sites can be interconnected as well as providing application accessibility across different fabrics with independent and private namespaces.

  • Publication number: 20240244012
    Abstract: An endpoint group (EPG) can be stretched between the sites so that endpoints at different sites can be assigned to the same stretched EPG. Because the sites can use different bridge domains when establishing the stretched EPGs, the first time a site transmits a packet to an endpoint in a different site, the site learns or discovers a path to the destination endpoint. The site can use BGP to identify the site with the host and use a multicast tunnel to reach the site. A unicast tunnel can be used to transmit future packets to the destination endpoint. Additionally, a stretched EPG can be segmented to form a micro-stretched EPG. Filtering criteria can be used to identify a subset of the endpoints in the stretched EPG that are then assigned to the micro-stretched EPG, which can have different policies than the stretched EPG.

  • Publication number: 20240205138
    Abstract: In one embodiment, a method includes identifying a problematic event between a first interest point and a second interest point of a network and activating, in response to identifying the problematic event between the first interest point and the second interest point, a first endpoint associated with the first interest point and a second endpoint associated with the second interest point. The method also includes receiving, from the first endpoint and the second endpoint, telemetry data associated with a problematic path between the first interest point and the second interest point. The method further includes determining the problematic path between the first interest point and the second interest point using the telemetry data received from the first endpoint and the second endpoint.

  • Patent number: 11757935
    Abstract: Methods to secure against IP address thefts by rogue devices in a virtualized datacenter are provided. Rogue devices are detected and distinguished from a migration of an endpoint in a virtualized datacenter. A first hop network element in a one or more network fabrics intercepts a request that includes an identity of an endpoint and performs a local lookup for the endpoint entity identifier. Based on the lookup not finding the endpoint entity identifier, the first hop network element broadcasts a message such as a remote media access address (MAC) query to other network elements in the one or more network fabrics. Based on the received response, which may include an IP address associated with the MAC address, the first hop network element performs a theft validation process to determine whether the request originated from a migrated endpoint or a rogue device.

  • Patent number: 11405427
    Abstract: The present technology pertains to a system, method, and non-transitory computer-readable medium for orchestrating policies across multiple networking domains. The technology can receive, at a provider domain from a consumer domain, a data request; receive, at the provider domain from the consumer domain, at least one access policy for the consumer domain; translate, at the provider domain, the at least one access policy for the consumer domain into at least one translated access policy understood by the provider domain; apply, at the provider domain, the at least one translated access policy understood by the provider domain to the data request; and send, at the provider domain to the consumer domain, a response to the data request.
