    Abstract: An application monitoring system for collecting, utilizing, and/or exchanging state information (e.g., application state and network state), configuration information, and/or other information to make network optimizations for applications orchestrated by an application orchestration system. The application monitoring system may include an application orchestrator discovery component that is configured to determine a presence of an application orchestration system for orchestrating applications. The application monitoring system may also include one or more application watch components for monitoring, among other things, application state, application configuration, and/or application replicas. The application monitoring system may further include a network state propagation component configured to provide network state information to the orchestration system.

    Abstract: Techniques for extending network elements to inspect, extract, and complement tracing information added to L7 flows by application distributed tracing systems. The techniques may include receiving a Layer-7 (L7) message of an L7 flow associated with a distributed application and determining that the L7 message includes tracing information. In some examples, the tracing information may be mapped to a marking that is to be included in a Layer 3 (L3) or Layer-4 (L4) packet carrying the L7 message, and the L3 or L4 packet including the marking may be sent to an L3 or L4 network element. In some examples, the L3 or L4 network element may be configured to utilize the marking to determine a network decision for the L3 or L4 packet.

    Abstract: A first map request message is sent from a source network device to a mapping network device to determine a destination network device associated with a destination endpoint device and a security association between the source network device and the destination network device. A first response message is received at the source network device that includes data indicating a mapping between the destination network device and the destination endpoint device and data indicating a security association between the source network device and the destination network device. The data is stored at the source network device. A second map request message is sent from the source network device to the mapping network device to update the data indicative of the mapping or the security association. A second response message is received at the source network device from the mapping network device.

    Abstract: Technologies are provided in example embodiments for associating a subscriber list to mapping data of a virtual machine, adding subscriber information of a network device to the subscriber list when a map request for the mapping data is received from the network device, and purging the subscriber information from the subscriber list when a preconfigured time period assigned to the subscriber information expires. In particular embodiments, the subscriber information includes an identification of the network device and the mapping data includes a virtual address of the virtual machine mapped to a physical address of the virtual machine. More specific embodiments include sending a notification signal with new mapping data of the virtual machine to each one of one or more network devices identified in corresponding subscriber information stored in the subscriber list. In further specific embodiments, the network device is either a map server or a map resolver.
