Abstract: Systems and methods are provided for receiving bandwidth metrics from a plurality of routers on respective link routes in a network, compiling a link database including the bandwidth metrics of each respective link route in the network, selecting a first designated link path from the link database between a first router and a second router based on an application routing policy, the application routing policy being based on a routing metric, providing a first multiprotocol label switching label based on the first designated link path to the first router of the plurality of routers in the network, and restricting network traffic of the first router to the first designated link path provided in the first multiprotocol label switching label.

Abstract: In one embodiment, an edge device located at an edge of a local network provides connectivity between the local network and a cloud-based software as a service (SaaS) provider via one or more interfaces. The edge device obtains telemetry data associated with the edge device for a plurality of metrics. The edge device makes a determination that one or more of the plurality of metrics is anomalous. The edge device sends, based on the determination, an indication of the determination to the SaaS provider. The SaaS provider uses the indication to determine a root cause of an application served by the SaaS provider experiencing degraded application performance.

Abstract: Local switching may be provided over a flexible cross-connect VLAN-aware based service. First, a failure of a first segment link of a first segment may be detected by a first network device. The first segment may have a first segment identifier and the first segment link may be connected to the first network device. Next, a route withdraw indicating the first segment identifier may be sent by the first network device in response to detecting the failure of the first segment link of the first segment. A second network device may then receive the route withdraw. Then, the second network device may forward, in response to receiving the route withdraw, traffic received from the first network device to a second segment link of the first segment connected to the second network device. The traffic may be received from the first network device over a backup connection over an Ethernet Virtual Private Network (EVPN) core.

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.

Abstract: Presented herein are methodologies for tracking a link state of a physical network connection and selectively reporting the link state to virtual machines that rely on the physical network connection. A method includes receiving an indication, at a hypervisor, which is running on a host computer and which instantiates a virtual switch, that a physical link interconnecting the host computer to a network has failed; determining that the physical link serves the virtual switch; determining whether link state tracking is enabled for the physical link; and when link state tracking is enabled for the physical link, notifying a virtual machine, which is running on the host computer and which is being served by the virtual switch, that a connection between the virtual machine and the network has failed.
