  • Patent number: 12328357
    Abstract: A request is received from a client device over a Virtual Private Network (VPN) tunnel. The request is received at a first one of a plurality of edge servers of a distributed cloud computing network. A destination of the request is determined and an optimized route for transmitting the request toward an origin server is determined. The optimized route is based at least in part on probe data between edge servers of the distributed cloud computing network. The request is transmitted to a next hop as defined by the optimized route.

  • Publication number: 20240093255
    Abstract: The present invention provides a novel biosynthetic production process which converts L-galactose into 2?-fucosyllactose via four enzymatically catalyzed reaction steps. The present process is designed such that co-factors required by the process are regenerated within the four reaction steps, hence making the process cost-effective and efficient. The process can be performed in vitro in a cell-free system. The present invention also provides mutant enzymes that can be used to increase production levels of 2?-fucosyllactose, whether using the novel pathway described herein or the mannose-dependent pathway known in the art.
