Provisioning a Network Node for Attribute Sharing

Techniques for provisioning a network node for attribute sharing are described. According to various implementations, a cloud-based connectivity service maintains network path information that identifies routing paths for routing communication sessions across different networks. The connectivity service also tracks whether particular network nodes across the different paths are provisioned with an attribute sharing functionality. An entity such as a communication service and/or a client device can query the connectivity service for a routing path for routing a communication session, and the connectivity service can respond identifying a routing path. In at least some implementations, the connectivity service selects a routing path based on a historical and/or real-time signal quality for the routing path.
