We study the performance of Concurrent Multipath Transfer using SCTP multihoming (CMT) in the presence of a bounded receive buffer (rbuf). We demonstrate using simulation that if two paths are used for CMT, the lower quality (i.e., higher loss rate) path degrades overall throughput of an rbufconstrained CMT association by blocking the rbuf. We argue that rbuf blocking is not specific to the tra...

SCTP is a general-purpose Transport Layer protocol with out-of-the-box support for multi-streaming as well as multihoming. A protocol extension, which is denoted as CMTSCTP, extends SCTP by supporting Concurrent Multipath Transfer (CMT). That is, multiple network paths are utilized simultaneously in order to improve the payload data throughput. However, dissimilar paths – i.e. paths having diff...

The project The Forking Paths aims to create a set of interactive cinematographic narratives, within an applied research that seeks to transfer the spectator from an extradiegetic level to an intradiegetic level, creating a metalepsis. The intention is, above all, to analyze the possibilities of the spectator’s identification as the main character, by the manipulation of the idea of time in Cin...

Due to the increasing reliance of our society on the timely and reliable transfer of large quantities of information (such as voice, data, and video) across high speed communication networks, it is becoming important for a network to offer survivability, or at least graceful degradation, in the event of network failure. In this paper we aim to offer a solution in the selection of the K-best dis...

Combination of gyro north-finder, self-collimation photoelectric theodolite can be composed a ground rapid directional aiming system. In the paper, based on the CCD angle measurement technology, the self-collimation optical system is redesigned, focal length of the optical system is calculated, and the appropriate parameters are chosen. Optical conjugate design of the three light paths of light...

This paper represents a technique for finding optimal paths with multiple indexes in a graph. Up to the present time, all optimal paths have been determined upon one index, say, distance for which an evaluation method exists. In this paper firstly we define multiple indexes for each edge in such a way that anyone can treat the factor for assigning an optimal path. Here, we use Data Envelopment ...

With ubiquitous computing and network access now a reality, multiple network conduits are become widely available to mobile as well as static hosts: for instance wired connections, 802.11 style LANs, Bluetooth, and cellular phone modems. Selection of the preferred mode of data transfer is a dynamic optimization problem which depends on the type of application, its bandwidth/latency/jitter requi...

In SCTP's Concurrent Multipath Transfer, if data is sent to the destined IP(s) without knowledge of the paths condition, packets may be lost or delayed. This is because of the bursty nature of IP traffic and physical damage to the network. To offset these problems, network path status is examined using our new mechanism Multipath State Aware Concurrent Multipath Transfer using redundant transmi...

S o you have a hot discovery, the paper has been published,and the patent has been filed.You may even have discussed setting up a business venture to exploit this advance with your University’s technology-transfer office.But what are the chances of commercial success? The odds are seemingly stacked against you.Even in biomaterials — a field with a long history in technology transfer — less than...

Based on a local approximation of the Riemannian distance on a manifold by a computationally cheap dissimilarity measure, a time discrete geodesic calculus is developed, and applications to shape space are explored. The dissimilarity measure is derived from a deformation energy whose Hessian reproduces the underlying Riemannian metric, and it is used to define length and energy of discrete path...
