    摘要： Method and system for providing time-critical services via a flow control environment, wherein at least one respective server component is provided for each service, wherein the server component is formed by a flow control component that is loadable into the flow control environment and executed there, where a configuration unit for at least one gateway component of a subnetwork forming the flow control environment ascertains globally valid access information associated with respective addressing information of the server components that is valid within the subnetwork, based on a mode of operation predefined via the configuration unit, one or more gateway components connected in parallel and/or in series are used, and where the at least one gateway component forwards service access requests to the server components in accordance with the forwarding and/or filter rules and the mode of operation.

    摘要： Techniques are presented herein to facilitate latency measurements in a networking environment. A first network device receives a packet for transport within a network domain that comprises a plurality of network devices. The plurality of network devices have a common time reference, that is, they are time synchronized. The first network device generates timestamp information indicating time of arrival of the packet at the first network device. The first network device inserts into the packet a tag that comprises at least a first subfield and a second subfield. The first subfield comprising a type indicator to signify to other network devices in the network domain that the tag includes timestamp information, and the second subfield includes the timestamp information. The first network device sends the packet from to into the network domain to another network device. Other network devices which receive that packet can make latency measurements.

    摘要： A search space blind detection method and a communication apparatus. The method includes: a terminal receives indication information that corresponds to a first search space set and that is sent by a network device, where the indication information is used to indicate one or more search space groups, one search space group includes at least two search spaces having an association relationship, and at least one search space in one search space group belongs to the first search space set; and then, the terminal determines, based on the indication information, a quantity of blind detection times corresponding to the first search space set. The quantity of blind detection times corresponding to the first search space set is determined by considering an association relationship between a plurality of search spaces.
