An antenna includes a substrate and a radiator fixed to the substrate. A thermal protection system for the antenna includes a thermal protection sheet body opposite to and spaced from the antenna, where the thermal protection sheet body separates the antenna from an external heat source; and a groove body formed in the thermal protection sheet body, where the radiator generates an antenna near field toward the outside, and an inner wall of the groove body is adapted to an edge of the antenna near field to reduce the deterioration of antenna performance caused by the thermal protection sheet body. The overall electrical performance and the thermal protection performance of the thermal protection system can be well balanced by decreasing the thickness of a middle area of the thermal protection system or by etching a groove in a certain shape in the thermal protection system.

Example methods and systems for validation-based service request handling are described. In one example, a computer system may obtain, from a management entity, configuration information specifying a unicast service address associated with a service node capable of providing a network service. In response to detecting a service request from the virtualized computing instance, the computer system may generate a modified service request that (a) is destined for the unicast service address and (b) includes a validation identifier (ID) associated with the virtualized computing instance. The modified service request may be forwarded towards the service node to cause the service node to perform validation based on the validation ID to determine whether to provide the network service. In response to detecting a service response from the service node, the service response, or a modified service response, may be forwarded towards the virtualized computing instance.

Validation-based service request handling

Some embodiments provide a method of identifying packet latency in a software defined datacenter (SDDC) that includes a network and multiple host computers executing multiple machines. At a first host computer, the method identifies and stores (i) multiple time values associated with several packet processing operations performed on a particular packet sent by a first machine executing on the first host computer, and (ii) a time value associated with packet transmission through the SDDC network from the first host computer to a second host computer that is a destination of the particular packet. The method provides the stored time values to a set of one or more controllers to process to identify multiple latencies experienced by multiple packets processed in the SDDC.

Example methods and systems for a network management entity to perform topology-aware control information dissemination in a software-defined networking (SDN) environment. The method may comprise obtaining group topology information specifying a network group, and a network configuration object that references the network group. The method may also comprise: processing the group topology information to identify, from multiple members of the network group, a first member that is relevant to a first host; and processing the group topology information to identify, from the multiple members, a second member that is irrelevant to the first host. The method may further comprise: generating and sending, to the first host, control information associated with a subset of the network group. The subset may include the first member but exclude the second member.
