Abstract: Techniques are described for learning an unknown virtual network information, such as an virtual Internet Protocol (IP) address, of a pod in a virtual network. In some examples, a virtual router executing at a computing device may receive an Address Resolution Protocol (ARP) packet from a virtual execution element in the virtual network, the virtual execution element executing at the computing device. The virtual router may determine, based at least in part on the ARP packet, whether virtual network information for the virtual execution element in a virtual network is known to the virtual router. The virtual router may, in response to determining that the virtual network information of the virtual execution element in the virtual network is not known to the virtual router, perform learning of the virtual network information for the virtual execution element.

Abstract: Processes are disclosed for the separation of hydrogen sulfide from feedstreams containing hydrogen sulfide and hydrocarbons by adsorption using a clinoptilolite adsorbent containing cations having ionic radii of from about 1.10 to 1.40 Angstroms. The processes can provide substantially enhanced adsorption capacities as compared with other adsorbents such as Zeolite 4A. As a result, a throughput of existing sulfur adsorption plants can be increased, e.g., by about 100%. The processes can be operated at elevated adsorption temperatures, e.g., greater than about 200.degree. F., and thus are particularly suitable when integrated with other processing steps such as hydrocarbon conversion reactions that utilize catalysts which are sulfur-sensitive. In addition, the clinoptilolite adsorbents of the present invention have a high tolerance to environments that comprise halides, e.g., HCl.
