Abstract: Provided is an infrastructure for enforcing target service level parameters in a network. In one example, a network service level agreement (SLA) registry obtains one or more input service level parameters for at least one service offered by an application. Based on the one or more input service level parameters, the network SLA registry provides one or more target service level parameters to a plurality of network controllers. Each network controller of the plurality of network controllers is configured to enforce the one or more target service level parameters in a respective network domain configured to carry network traffic associated with the application.

Abstract: Techniques for steering overlay network traffic along specific paths through an underlay network. The techniques may include determining a path through an underlay network that is optimized for sending a packet from a first node of an overlay network to a second node of the overlay network. The techniques may also include determining a destination address for sending the packet along the path from the first node to the second node, the destination address including a micro segment identifier (uSID) corresponding with an underlay node that is disposed along the path through the underlay network and trailing bits representing a portion of an address that corresponds with the second node. The techniques may also include causing the packet to be modified to include the destination address such that the packet is sent from the first node to the second node along the path.

Abstract: Techniques for enabling a network access provider to make automatic Software as a Service (SaaS) optimization decisions. Among other things, the techniques may include determining a SaaS application that is being accessed by client endpoints via flows through a network access provider. The techniques may also include determining, based at least in part on a policy associated with the network access provider, whether to enable network optimizations for traffic through the network access provider to the SaaS application. Based at least in part on a determination that the network optimizations are to be enabled for the traffic to the SaaS application, the techniques may include installing a service definition associated with the SaaS application in a service policy database of the network access provider.

Abstract: Techniques for using application network requirements and/or telemetry information from a first networking technology to enhance operation of a second networking technology and optimize wide area network traffic are described herein. The techniques may include establishing a communication network for use by applications of a scalable application service platform, the communication network including a first networking technology and a second networking technology. In this way, a request to establish a connection for use by an application may be received by the first networking technology. The request may include an indication of a threshold service level of the connection. In response to the request, the first networking technology may determine whether the second networking technology is capable of hosting the connection. If the second networking technology is capable of hosting the connection, the connection may be established such that application traffic is sent or received using the second networking technology.

Abstract: Techniques for obtaining application network metadata from a service registry so that a network routing policy may be derived for traffic associated with the application are described herein. The techniques may include receiving, at a service registry, network metadata associated with traffic of an application hosted by a scalable application service platform. The techniques may also include obtaining, by a controller of a network and from the service registry, the network metadata associated with the traffic of the application. Based at least in part on the network metadata, the controller may determine a routing policy that is optimized for sending the traffic through the network. Additionally, the controller may send an indication of the routing policy to a node of the network or otherwise provision the network such that the traffic of the application is sent through the network according to the routing policy.

Abstract: Techniques for dynamic routing based on application load are described herein. The techniques may include receiving load information associated with resources of an application orchestration system that are allocated to host an application, the resources associated with different geographical regions. Based at least in part on the load information, a network controller may determine that first resources of the application orchestration system are less constrained than second resources of the application orchestration system, the first resources associated with a first geographical region and the second resources associated with a second geographical region. Based at least in part on the first resources being less constrained than the second resources, application traffic may be routed through the network to the application hosted by the first resources in the first geographical region.
