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 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: Systems, methods, and computer-readable media for locally applying endpoint-specific policies to an endpoint in a network environment. A network device local to one or more endpoints in a network environment can receive from a centralized network controller one or more network-wide endpoint policies. A first endpoint of the one or more endpoints can be configured to inject policy metadata into first data traffic. Policy metadata injected into the first traffic data can be received from the first endpoint. The network device can determine one or more first endpoint-specific polices for the first endpoint by evaluation the first policy metadata with respect to the one or more network-wide endpoint policies. As follows, the one or more first endpoint-specific policies can be applied to control data traffic associated with the first endpoint.

A threat aware controller uses a threat feed provided by a threat intelligence service to establish a threat detection engine on virtual switches. The threat aware controller and threat detection engine work together to detect any anomalous or malicious behavior of network traffic on the virtual switch and established virtual network functions to quickly detect, verify, and isolate network threats.

Abstract: Techniques for signaling, to a network controller, a connection state of a proxy for use by the network controller to correlate proxied-connections with application pairs for traffic optimization. In some examples, the techniques may include receiving, at a controller of a network, control plane information associated with a proxy that manages a proxied flow through the network. Based on the control plane information, the controller may determine that application traffic is flowing across the proxied flow between a first application and a second application. In this way, based at least in part on a policy associated with at least one of the first application or the second application, the controller may reconfigure a network element of the network for optimizing the application traffic flowing across the proxied flow.
