Abstract: Embodiments herein describe association rules (e.g., affinity and anti-affinity rules) that a wireless device can use to optimize its performance in a Wi-Fi network. While BSS coloring is typically used to eliminate color collisions, the embodiments herein use BSS coloring to define what BSS colors should be on the same channel and which should not. For example, an affinity rule can indicate that a wireless device assigned a first BSS color (e.g., red) can share the same channel with wireless devices (or BSSs) assigned a second BSS color (e.g., green). In contrast, an anti-affinity rule can indicate that a wireless device in the red BSS color cannot share a channel with a wireless device assigned to a third BSS color (e.g., blue). The embodiments herein permit the wireless devices to be grouped with, or separated from, wireless devices having different BSS colors.

Abstract: Techniques for deploying, monitoring, and modifying network topologies operating across multi-domain environments using formal models and weighting factors assigned to computing elements in the network topologies. The weighting factors restrict or allow the movement of various computing elements and/or element groupings to prevent undesirable disruptions or outages in the network topologies. Generally, the weighting factors may be determined based on an amount of disruption experienced in the network topologies if the corresponding computing element or grouping was migrated. As the amount of disruption caused by modifying a particular computing element increases, the weighting factor represents a greater measure of resistivity for migrating the computing element. In this way, topology deployment systems may allow, or disallow, the modification of particular computing elements based on weighting factors. Thus, the amount of disruption in the functioning of network topologies may be considered when optimizing the allocation of computing elements across multi-domain environments.

Abstract: Techniques are described herein for generating and modifying formal network topology models, and deploying network topologies based on the formal models across multiple workload resource domains. A topology deployment system may receive modification data for a deployed network topology, and analyze the modification data to determine whether the associated formal network topology model is to be recomputed. In some examples, modifications to a deployed network topology that do not impact operational performance or compromise functional equivalence with the underlying logical model, need not trigger a recomputation of the network topology model immediately and could be delayed. Modifications to deployed network topologies that do not trigger recomputations of the formal network topology model may be stored and tracked, so that subsequent recomputations of the model may incorporate the pending modifications.

Abstract: Disclosed is a system and method of providing a segment routing as a service application. The method includes receiving a configuration of an internet protocol environment. The configuration can be a layer 3 configuration of a single cloud environment or even across multiple cloud environments. The configuration defines routing, forwarding, and paths in the environment between different entities such as virtual machines. The method includes receiving a parameter associated with a workload of a tenant. The parameter can be a service level agreement (i.e., a best bandwidth available), a pathway requirement, a parameter associated with specific workload, and so forth. Based on the configuration and the parameter, the method includes generating tenant-defined layer 3 overlay segment routing rules that define how the workload of the tenant will route data in the internet protocol environment using segment routing.

Abstract: A controller device sends predictions from a machine learning module to source endpoints. The controller receives flow information and network information from a network elements in a network. The flow information is associated with source routed data flows that traverse the network in source routed network paths. The network information is associated with network characteristics of each of the network elements included in at least one of the source routed network paths. The controller analyzes the flow information and the network information with machine learning to generate a prediction of at least one metric of source routing behavior within the network. The controller sends the prediction of the at least one metric to one or more source endpoints to optimize the source routed network paths used by future source routed data flows originating from the one or more source endpoints.
