Abstract: Systems and methods for dynamically establishing network overlay tunnels between edges within different groups of a network architecture are provided. According to an embodiment, a Software-Defined Wide Area Network (SDWAN) controller associated with a private network, receives a request to initiate a dynamic Virtual Private Network (VPN) link for a network session between a source edge and a destination edge. The SDWAN controller determines configuration information for each of the source edge and the destination edge, which includes VPN and SDWAN configuration information determined based on pre-configured rules managed by the SDWAN controller for generating the dynamic VPN link between the source edge and the destination edge. The SDWAN controller directs the source edge and the destination edge to set up a VPN overlay tunnel in accordance with the determined configuration information by pushing the determined configuration information to each of the source edge and the destination edge.

Abstract: The embodiments provide systems and methods for efficiently and accurately differentiating requests directed to uncacheable content from requests directed to cacheable content based on identifiers from the requests. The differentiation occurs without analysis or retrieval of the content being requested. Some embodiments hash identifiers of prior requests that resulted in uncacheable content being served in order to set indices within a bloom filter. The bloom filter then tracks prior uncacheable requests without storing each of the identifiers so that subsequent requests for uncacheable requests can be easily identified based on a hash of the request identifier and set indices of the bloom filter. Some embodiments produce a predictive model identifying uncacheable content requests by tracking various characteristics found in identifiers of prior requests that resulted in uncacheable content being served.
