Abstract: Example implementations relate to calculating a time to live (TTL). An example implementation includes receiving a transaction request containing a first time to live (TTL) from a requester. A second TTL for a transaction response may be computed, and a transaction response containing the second TTL may be transmitted.

Abstract: An example hierarchical switching device may include sub-switches that form a fully interconnected all-to-all network, wherein the sub-switches comprise external output ports, internal input ports and internal output ports to exchange packets with other sub-switches within the fully interconnected all-to-all network. The switching device may further include a deadlockable storage, a storage partition and a switch controller. The deadlockable storage space is exclusively assigned to an internal input port of the internal input ports of the sub-switch including the deadlockable storage. The storage partition is exclusively assigned to an external output port of the external output ports and exclusively assigned to the internal input port. The switch controller is to route a packet destined for an external output port of a sub-switch through the internal input port of the sub-switch to the deadlockable storage or if the packet corresponds to the external output port, to the storage partition.

Abstract: Example implementations relate to hybrid arbitration of requests for access to a shared pool of resources. An example implementation includes receiving a set of requests for access to the shared pool of resources. The requests may each be from any number of traffic classes. A traffic class may be selected according to turn-based arbitration logic. Additionally, a request from each traffic class of a subset of received requests may be selected. A request selected by the age-based arbitration logic and of the selected traffic class may be granted access to the shared pool of resources.

Abstract: A detection circuit is provided for a particular group of memory cells in a memory device, where the detection circuit is to be updated in response to at least one access of data and at least one neighboring group of memory cells. The particular group of memory cells is refreshed in response to an indication from the detection circuit, where the indication indicates presence of potential disturbance of the particular group of memory cells.

Abstract: Examples relate to virtual channel routing in networks considering VC actions to be performed by the packets while routed through the network. A packet is received at an input port of a network device of a network and an output port and a VC action is determined from a routing table associated to the input port based on a packet's destination network device. A VC mask is determined from a Virtual Channel Action Table (VCAT), associated to the routing table, based on a packet's ingress VC and the VC action. A particular VC among the set of VCs defined in the VC mask is selected and the packet is routed to the destination network device using the output port and the particular VC.
