  • Patent number: 11936564
    Abstract: Techniques for a TCP proxy to communicate over a LEO satellite network on behalf of a client device by selecting a TCP congestion-control algorithm that is optimal for the LEO satellite network based on the time of day and/or location of the TCP proxy. Based on the locations of satellites during the day as they traverse predefined and patterned orbital paths, different TCP congestion-control algorithms may be more optimized to communicate data through the LEO satellite network. However, client devices generally use a single TCP congestion-control algorithm to communicate over WAN networks. Accordingly, a TCP proxy may be inserted on, for example, a router to communicate with the client device using a TCP congestion-control algorithm that the client device is configured to use, but then communicate over the LEO satellite network using a different TCP congestion-control algorithm that is optimal based on the time of day and/or other factors.

  • Publication number: 20230421610
    Abstract: Techniques for expressing, communicating, de-conflicting, and enforcing consistent access policies between an IBN architecture and a Cloud-Native architecture. Generally, network administrators and/or users of a Cloud-Native architecture and an IBN architecture express access policies independently for the two different domains or architectures. According to the techniques described herein, a Network Service Endpoint (NSE) of the Cloud-Native architecture may exchange access policies with a network device of the IBN architecture. After exchanging access policies, conflicts between the sets of access policies may be identified, such as differences between allowing or denying communications between microservices and/or applications. The conflicts may be de-conflicted using various types of heuristics or rules, such as always selecting an access policy of the IBN architecture when conflicts arise.
