  • Publication number: 20240113968
    Abstract: Some embodiments provide an automated method for defining externally routable Pods within a Kubernetes cluster. In some embodiments, the Pod operates in a guest cluster has its own VPC (virtual private cloud) network in a datacenter with several other guest clusters that have their own VPC networks and their own set of managers. In some embodiments, a Pod within a GC can be made externally routable so that it can be directly addressable from an external client outside of the Pod's network by using two new Kubernetes CRDs (custom resource definitions), which are an IPPool CRD and a RouteSet CRD. Examples of such external clients include VMs or Pods in another GC or a supervisor cluster connected to the particular GC through a gateway, or from a machine outside of the network of all of the GCs or SC.

  • Patent number: 11936544
    Abstract: A system and method for capturing resource usage information in a network for namespaces in which pods operate are described herein. A data structure specifies a topology that includes a gateway and routing addresses in a network whose usage is to be captured. The data structure is provided to an API of a master node controlling the pods. A controller in the master node enforces the data structure and reports results back to the API.

  • Patent number: 11936546
    Abstract: The disclosure provides an example method for live packet tracing. Some embodiments of the method include configuring a first network interface of a first pod to mark each of a plurality of packets, with a corresponding flow tag and a corresponding packet identifier, receiving, from one or more observation points, at least one of copies or metadata of the plurality of packets each marked with the corresponding flow tag and the corresponding packet identifier. In some embodiments, the method further includes displaying data indicative of the at least one of the copies or the metadata of the plurality of packets.

  • Patent number: 11926339
    Abstract: A method and a system for constructing a driving coordinate system for use in the field of smart transport. The method for constructing a driving coordinate system comprises: determining the road boundary line on one side of the road on which a current vehicle is situated as a reference line for constructing a driving coordinate system; in a vehicle coordinate system, determining the reference line point having the smallest distance between the reference line and the current vehicle position as an origin point OF of the driving coordinate system; on the basis of the origin point OF, determining the road guiding line direction as the XF axis of the driving coordinate system and determining the direction relative to the road guiding line direction according to the left-hand rule as the YF axis of the driving coordinate system; and, on the basis of the origin point OF, the XF axis, and the YF axis, forming a corresponding driving coordinate system.

  • Patent number: 11878290
    Abstract: Disclosed is a method for reducing carbon deposits on a catalyst in recycling HFC-23. The recycling is realized by means of a fluorine-chlorine exchange reaction with HFC-23 and a halogenated hydrocarbon. The catalyst for the fluorine-chlorine exchange reaction comprises a main body catalyst and a precious metal. The precious metal is selected from at least one of Pt, Pd, Ru, Au or Rh, and has an addition amount of 0.01-2 wt %. During the fluorine-chlorine exchange reaction, hydrogen gas is introduced. The invention has advantages of good catalyst stability, long life, etc.

  • Publication number: 20220105504
    Abstract: Disclosed is a method for improving the stability of a catalyst in recycling HFC-23. The recycling is realized by means of a fluorine-chlorine exchange reaction with HFC-23 and a halogenated hydrocarbon. The catalyst for the fluorine-chlorine exchange reaction comprises a main body catalyst and a metal oxide, wherein the metal oxide is selected from at least one metal oxide of K, Na, Fe, Co, Cu, Ni, Zn or Ti, and has an addition amount of 0.1-5 wt %. The present invention has advantages such as a good catalyst stability, a long life, and a low content of by-product CFC-12.
