    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: Systems, methods, and computer-readable media are disclosed for a scalable process for validating multiple paths used for routing network traffic in a network using segment routing. In one aspect, a method includes identifying, by a first network hop, one or more second network hops, for each of the one or more second network hops, determining a corresponding flow label, the corresponding flow label including a corresponding test packet for validating packet forwarding between the first network hop and a corresponding second network hop, and performing a validation process for validating packet forwarding from the first network hop to the corresponding second network hop using at least the corresponding flow label. The method further includes determining a queue of additional network hops to be validated based on a result of the validation process, and iteratively validating packet forwarding for each additional network hop in the queue.

    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 optimizing segment routing (SR) paths using segment identifiers (SIDs) are disclosed, including determining a packet is to be sent from a first node to a second node of a network using an SR method. The techniques may also include determining a segment quantization factor that is representative of a first number of SIDs that are included in a segment quantization interval. Based at least in part on the segment quantization factor and a cost constraint, an SR path defined by a second number of SIDs to send the packet may be determined. The second number of SIDs may be associated with maximizing the SIDs included in individual ones of segment quantization intervals. The techniques further include modifying the packet to include at least the second number of SIDs and causing the packet to flow from the first node to the second node via the SR path.

    Abstract: Described herein are techniques directed to utilizing IP encapsulation to route data packets to different instances of a service in a network. In one aspect, a method includes generating a first request, which includes a first data packet and a first IP encapsulation; transmitting the first request to a service aware router, wherein the service aware router generates a second request that includes the first data packet and a second IP encapsulation, and transmits the service request to the instance of the service; receiving, from the service instance, a response including a second data packet and a third IP encapsulation, which includes an identifier of the service instance of the service; and recording the identifier of the service instance, wherein subsequent requests for applying the service to data packets originating at the device are directly transmitted by the device to the service instance.
