    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 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 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 tracking compute capacity of a scalable application service platform to perform dynamic bandwidth allocation for data flows associated with applications hosted by the service platform are disclosed. Some of the techniques may include allocating a first amount of bandwidth of a physical underlay of a network for data flows associated with an application. The techniques may also include receiving, from a scalable application service hosting the application, an indication of an amount of computing resources of the scalable application service that are allocated to host the application. Based at least in part on the indications, a second amount of bandwidth of the physical underlay to allocate for the data flows may be determined. The techniques may also include allocating the second amount of bandwidth of the physical underlay of the network for the data flows associated with the application.

    Abstract: Techniques for using proxies with overprovisioned IP addresses to demultiplex data flows, which may otherwise look the same at L7, into multiple subflows for L3 policy enforcement without having to modify an underlying L3 network. The techniques may include establishing a subflow through a network between a first proxy and a second proxy, the subflow associated with a specific policy. In some examples, the first proxy node may receive an encrypted packet that is to be sent through the network and determine, based at least in part on accessing an encrypted application layer of the packet, a specific application to which the packet is to be sent. The first proxy node may then alter an IP address included in the packet to cause the packet to be sent through the network via the subflow such that the packet is handled according to the specific policy.
