Abstract: A controller in a network can gather operational data describing performance of an end point group in the network. The end point group can include one or more containers providing microservices. The controller can calculate an overall health score for the end point group based on the operational data. The overall health score can indicate whether an actual overall performance of the end point group is meeting a desired overall performance of the end point group defined by a first set of policies assigned to the end point group. The controller can present, in a graphical user interface, a visual representation of the overall health score. The visual representation of the overall health score can indicate that the overall health score is within a first overall health range from a set of two or more overall health ranges.

Abstract: A controller in a network can gather operational data describing performance of an end point group in the network, wherein the end point group includes one or more containers providing micro services. The controller can calculate a health score for the end point group based on the operational data. The health score can indicate whether an actual performance of the end point group is meeting a desired performance of the end point group defined by a first set of policies assigned to the end point group. The controller can determine, based on the health score, that the actual performance of the end point group is not meeting the desired performance of the end point group, and modify the end point group to achieve the desired performance of the end point group.

Abstract: Disclosed are systems, methods, and computer-readable medium for adjusting group based policies. A controller in a network can gather operational data describing performance of an end point group (EPG) in the network. The EPG can be operating according to a first set of policies to achieve a desired performance for the end point group. The controller can calculate a health score for the end point group based on the operational data. The health score can indicate whether an actual performance of the end point group is meeting the desired performance of the end point group. The controller can determine, based on the health score, that the actual performance of the end point group is not meeting the desired performance of the end point group, and apply a second set of policies to the end point group to achieve the desired performance of the end point group.

Abstract: In one embodiment, for each port of an access node in an access-based computer network, one access server of a plurality of access servers is configured as a preferred access server for that port. Upon receiving a session initiation message at a particular port, the access node forwards the session initiation message to one or more of the access servers based on the configured preferred access server for the particular port.

Abstract: In one embodiment, a provider edge (PE) device in a computer network determines an IPv4 address and link-layer address for each adjacent customer premise equipment (CPE) device, and assigns each CPE device a unique IPv6 address. The PE device stores a key-pair mapping between the unique IPv6 address and combined IPv4 and link-layer address for each adjacent CPE, the mapping bound by a CPE session context, and uses the CPE session context to convert between IPv4 and IPv6 for all network traffic to and from a particular CPE device.

Abstract: An example method for automating monitoring using configuration event triggers in a network environment is provided and includes receiving a change request for a configuration change, creating a change impact monitor according to a profile associated with the configuration change, taking a first snapshot of performance indicators when the configuration change is applied, taking a second snapshot of the performance indicators a predetermined duration after applying the configuration change, and generating a change impact notification describing the first snapshot and the second snapshot. The profile can specify the performance indicators for the configuration change. A change agent that creates the change impact monitor may also be invoked. In some embodiments, the method can further include receiving a soak command, and taking a third snapshot of the performance indicators before applying the configuration change.

Abstract: A method for translating network addresses includes receiving a first network packet, the first network packet comprising an internal source address. The method also includes generating, by performing a mapping operation, a mapping value. The generating of the mapping value uses, at least in part, at least a portion of the internal source address, and at least a portion of an external source address. The external source address is associated with the internal source address. The method also includes forwarding, using a second network packet, at least a portion of the first network packet. The second network packet comprises the external source address and at least a portion of the mapping value.

Abstract: A network analytics controller is established in a network. The network includes a plurality of nodes. A plurality of network analytics agents is established; each agent at a node of the network. Network analytics configuration parameters, including a network analytics scope, are received at the networks analytics controller. A task is assigned to each agent at a node determined to be within the network analytics scope, the task comprising that portion of the network analytics specified in the network analytics configuration parameters relevant to the corresponding node. The assigned task is performed at each agent assigned a task. The networks analytics controller receives the results of each performed task, and aggregates the received results.

Abstract: Systems and methods provide for scaling service discovery in a micro-service environment. A controller can inject a service discovery agent onto a host. At least one of the controller or the agent can identify a first set of micro-service containers that are dependencies of the first micro-service container and a second set of micro-service containers that are dependencies of the second micro-service container. At least one of the controller or the agent can update routing data for the first set of micro-service containers and the second set of micro-service containers. At least one of the controller or the agent can determine the second micro-service container has terminated on the host computing device. At least one of the controller or the agent can update the agent to remove the routing data for the second set of micro-service containers.
