Abstract: A system with a local network and a set of remote networks is described herein. A subnet address range associated with the local network is subdivided into sub-segment address ranges. Each remote network is assigned a sub-segment address range for communicating with the local network. Each sub-segment address range is a smaller part of the original subnet range and each sub-segment range does not overlap with other sub-segment address ranges. Using an intermediate-local function device of the local network and intermediate-remote function devices of the remote networks, client stations in both the local and remote networks may seamlessly communicate using their native private addresses as destination addresses and without indirect address mapping.

Abstract: A wireless terminal apparatus in a communication system shares a reference cycle with a data center. The reference cycle includes an incoming-call acceptance ready time that ranges from an incoming-call acceptance start time point to an incoming-call acceptance end time point. The incoming-call acceptance start time point corresponds to an outgoing-call generation time point of generating an outgoing-call by the data center. The outgoing-call generation end time point is set in consideration of a delay in the outgoing-call. The wireless terminal apparatus is set in an intermittent standby state that is contained in the incoming-call acceptance ready time. In the remaining time excluding the incoming-call acceptance ready time within the reference cycle, the wireless terminal apparatus is set in a sleep state in which no incoming-call is accepted.

Abstract: Aspects for reducing interference between networks are provided.

A level of utilization of the communications medium by the one or more devices in the first network can be estimated based at least in part on a signal strength of the signal and the one or more parameters. A period of time for communicating in a second network over the communications medium using the unlicensed frequency spectrum can be adjusted based at least in part on the level of utilization of the communications medium by the first network.

Abstract: Machines in a managed network implement a set of rules that cause individual machines to directly interact with only a small number of machines in the network. Independent local actions of the individual machines collectively cause the individual machines to be self-organized into one or more communication orbits without any global control or coordination by a server or an administrator. The communication orbits are used for supporting security management, including, at a first node of the network, receiving a security management message from an upstream neighbor through a respective receiving channel from the upstream neighbor to the first node; performing one or more security management operations in accordance with the security management message received from the upstream neighbor; and forwarding the security management message to a downstream neighbor through a respective propagation channel from the first node to the downstream neighbor.

Abstract: A system using the Ethernet OAM functionality for finding the smallest of hop-specific data transfer speeds related to a data transfer path from a first network element (101) to a second network element (102) is presented. The first network element is configured to transmit, to the second network element, first data including an Ethernet OAM message. Each intermediate network element (104, 105) located on the data transfer path is configured to update the first data to indicate so far smallest of the hop-specific data transfer speeds when the first data passes through the intermediate network elements. After receiving the first data, the second network element transmits, to the first network element, second data indicating the smallest of the hop-specific data transfer speeds. Thus, the first network element can be made aware of capacity changes taking place on the data transfer path.

Abstract: Disclosed are methods and systems for setting a timeout period. In particular, a BS may have data storage defining a buffer. Also, the BS may be configured to (i) provide an air interface through which the BS serves UEs, (ii) buffer data packets destined to individual UEs, and (iii) apply a buffer timeout process according to which the BS drops a data packet from the buffer in response to that data packet being in the buffer for a timeout period. As such, the BS may make a determination that a served UE is a relay-UE that provides wireless backhaul connectivity for a relay-BS, and may set the timeout period based on the determination. When the BS then applies the buffer timeout process, the BS drops a data packet from the buffer in response to that data packet being in the buffer for the timeout period set based on the determination.

Abstract: A direct network is described in which each resource is connected to a switching fabric via a set of two or more routing nodes. The routing nodes are distributed so as to satisfy at least one inter-node separation criterion. In one case, the separation criterion specifies that, for each resource, a number of routing nodes that share a same coordinate value with another routing node in the set (in a same coordinate dimension) is to be minimized. In some network topologies, such as a torus network, this means a number of unique loops of the direct network to which each resource is connected is to be maximized. The routing provisions described herein offer various performance benefits, such as improved latency-related performance.
