    Abstract: Provided are an apparatus and method for improving transmission control protocol (TCP) performance using path recovery notification over a wireless network. The apparatus includes: a path recovery manager which detects a mobile host recovered from a temporary disconnection state and then outputs a detection signal to notify the detection result; a path recovery notification manager which receives the detection signal and generates an ACK (acknowledgement) packet to inform a transmitting end that the mobile host is recovered; and a first packet transceiver which transmits/receives the generated ACK packet and a data packet. Accordingly, a temporary disconnection state of a wireless network is explicitly informed to a transmitting end so as to transmit only lost packets without performing unnecessary congestion control, thereby improving TCP performance.

    Abstract: Provided is a buffer system for adjusting first-in first-out, more particularly, a buffer system that temporarily stores a plurality of substrates and is capable of adjusting first-in first-out. The buffer system includes one or more buffer layers having shafts and rollers fitted and fixed to the shafts so as to temporarily store or transfer substrates, a vertically moving unit moving the buffer layers up or down such that a buffer layer having thereon a substrate to be transferred is connected to a driving unit, and the driving unit rotating the shafts of the buffer layer having thereon the substrate to be transferred to transfer the substrate.

    Abstract: Topology input is used to identify a set of data flows as between a set of virtual machines (VMs), as well as one or more network services for one or more of the data flows. A determination is made as to a minimal number of network service virtual machines (NSVMs) for use in providing the one or more network services. An arrangement is determined for server resources and network resources of the data center network on which a virtual network topology is provided for the tenant, including the set of VMs and the number of NSVMs.
