    摘要: The disclosed technology is directed towards locating and counting unused nodes, such as free Internet Protocol version 4 (IPv4) address blocks. A hierarchical structure of nodes is created from an origin block to a specified lower level, and the hierarchical structure is processed using mapping and eliminating to locate free nodes. A first node group comprises node(s) in use, a second node group identifies intermediate subnets between the first node of the first node group and the specified origin block, and a third node group identifies any subnets hierarchically below node(s) in use. Unused (free) node count information is obtained based on nodes below the origin block that are not in the first node group, the second node group, or the third node group.

    摘要: A wireless device (S) includes a radio (R) for communicating via a wireless communication protocol which employs messages constructed as layer 2 MAC frames each including a layer 2 MAC header and a payload. The wireless device is configured to operate in (i) a first mode in which the wireless device transmits messages (N0, . . . , Nn) via the radio each including an IPv6 packet header and an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame, and (ii) a second mode in which the wireless device transmits messages (M0, . . . , Mn) via the radio each including an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame without including the IPv6 header. A relay device (T) comprises a radio for communicating via the wireless communication protocol which employs messages constructed as layer 2 MAC frames each including a layer 2 MAC header and a payload. In one power-saving aspect, the relay device is configured to perform a header insertion service (I) in which the relay device receives messages (M0, . . . , Mn) via its radio from the wireless device (S), each including an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame without including the IPv6 header. The header insertion service inserts header information (A′) into the messages (M0, Mn) received from the wireless device (S) and retransmits the messages with complete headers as messages (M0′, . . . , Mn′). In another power-saving aspect, the relay device additionally or alternatively applies an acknowledgement detection criterion to filter out acknowledgements received from the server, and forwards the filtered out acknowledgements to the wireless device (S) via the radio at a reduced rate.

    摘要: In one embodiment, a computer networking device calculates a first hash value for an identifier of a group of computing devices, as well as a second hash value for the identifier of the group of computing devices, with each hash value being at least in part on the identifier of the group of computing devices and an identifier of the respective interface. The computer networking device may also analyze the first hash value with respect to the second hash value and select the first interface for association with the identifier of the group of computing devices based at in part on the analyzing. The computer networking device may further store an indication that the identifier of the group of computing devices is associated with the first interface.

    摘要: A method is provided in one example embodiment and includes, for each of a plurality of individual storage units collectively comprising a virtual storage unit, mapping an internal address of the storage unit to a unique IP address, wherein each of the storage units comprises a block of storage on one of a plurality of physical storage devices and wherein the IP address includes a virtual storage unit number identifying the virtual storage unit; receiving from a client a request to perform an operation on at least one of the data storage units, wherein the request identifies the internal address of the at least one of the data storage units; translating the internal address of the at least one of the data storage unit to the unique IP address of the at least one of the data storage units; and performing the requested operation on the at least one of the data storage units.

    摘要: In an approach, a processor creates a local first Pod API object in a first lower Kubernetes cluster based on a first Pod API object in an upper Kubernetes cluster, where: the local first Pod API object includes internal and external network descriptions for a Pod described in the local first Pod API object, and the upper cluster manages the first and second lower Kubernetes cluster. A processor adds an annotation for the Pod to the local first Pod API object and the first Pod API object. A processor creates a local endpoint API object in the first lower cluster based on an endpoint API object in the upper cluster and annotations of Pods in the upper cluster. A processor redirects the first request to the endpoint of the second Pod described in the local endpoint API object.
