Disconnected mobile ad hoc networks (or D-MANETs) are partially or intermittently connected wireless networks, in which continuous end-to-end connectivity between mobile nodes is not guaranteed. The ability to selfform and self-manage brings great opportunities for D-MANETs, but developing distributed applications capable of running in such networks remains a major challenge. A middleware syste...

The past several years have witnessed the rapid progress of end-to-end Neural Machine Translation (NMT). However, there exists discrepancy between training and inference in NMT when decoding, which may lead to serious problems since the model might be in a part of the state space it has never seen during training. To address the issue, Scheduled Sampling has been proposed. However, there are ce...

The provision of end-to-end Quality of Service (QoS) for multimedia services over IP-based networks is already an open issue. To achieve this goal, service providers need to manage Service Level Agreements (SLAs), which specify parameters of the services operation such as availability and performance. Additional mechanisms are needed to quantitatively evaluate the user-level SLA parameters. Thi...

Most successful deep learning models for action recognition generate predictions for short video clips, which are later aggregated into a longer time-frame action descriptor by computing a statistic over these predictions. Zeroth (max) or first order (average) statistic are commonly used. In this paper, we explore the benefits of using second-order statistics. Specifically, we propose a novel e...

IPv6 provides an expanded address space to satisfy the future Internet requirements. In this paper we compare and analyze onemonth measurements of the end-to-end IPv6 delay and hopcount between 26 testboxes of the RIPE TTM project with the corresponding parts in IPv4 network. By comparing IPv6 and IPv4 paths, we focus on problems that are only present in the IPv6 paths. In those poorly performi...

Realm Speciic IP (RSIP) is a new architecture under consideration in the Internet Engineering Task Force (IETF) that can potentially alleviate some of the problems associated with partitioning of the In-ternet address space due to, for example, the shortage of IPv4 addresses. It is being positioned as a replacement for Network Address Translation (NAT), because, among other things, it can suppo...

Low Earth Orbit (LEO) satellite networks are characterized by topology variations. Although space segment topology varies periodically, connections of mobile stations (MS’s) to the satellite network alter stochastically. As a result the quality of service delivered to users may degrade. Different procedures have been proposed either as part of a resource allocation mechanism or as part of an en...

Large-scale network testbeds raise the problem of the exhaustion of IPv4 address space. Before the IPv6 is widely deployed, multiplexing IPv4 address for guest slivers is necessary. NAT is one of the typical ways for the multiplexing. Violating the end-to-end feature of the Internet, the NAT approach has well-known drawbacks in performance scalability and in supporting diverse services and appl...
