Recent years in the field of mobile communications have brought two significant requirements – seamless service delivery and Quality of Service provisioning. Seamless mobility goes hand in hand with Mobile IPv6 protocol and various handover schemes of this protocol are trying to solve the QoS issue. In this paper we are presenting a method for evaluation of the Layer 3 handover schemes from the...

Multi-FPGA boards are being used for logic emulation, rapid prototyping, custom computing and low volume subsystem implementation. A key feature which characterizes these boards is their routing architecture(RA). Inter-FPGA connections in an RA can be of two types, namely fixed connections through direct wires and programmable connections through intermediate Field-Programmable Interconnect Dev...

In this paper, we address the routability and analog performance issues involved in routing for array-based FPAAs that have single-segment horizontal and vertical routing resources. We then present FAAR (Field-programmable Analog Array Router) and describe a routing algorithm developed for the target array-based FPAA architecture. Sequential routing technique is used for routing multi-terminal ...

Mobile IP allows a mobile node to roam into a foreign IP network without losing its connection with its peer. Mobile IPv6 uses Route Optimization to improve the routing performance by avoiding the triangle routing problem and adopting Return Routability as a secure process for binding update. Host Identity Protocol (HIP) is an experimental security protocol which provides mobility management an...

Modern three-dimensional (3D) designs, in which the active devices are placed in multiple layers using 3D integration technologies, are helping to maintain the validity of Moore’s law in today’s nano era. However, progress in commercial 3D ICs has been slow due to multiple reasons. One of them is the lack of appropriate physical design (layout) tools that take the new constraints arising from t...

Abstract Reliability engineering of railway infrastructure aims to understand failure processes and improve the efficiency effectiveness investments maintenance planning such that a high quality service is achieved. While formal methods are widely used verify design specifications safety-critical components in train control, quantitative analyze reliability associated with specific system desig...

With increasing scale of Field Programmable Gate Arrays (FPGAs), architecture of interconnect resources (IRs) in FPGA is becoming more and more complicated. IR testing plays an important role to guarantee correct functionality of FPGAs. Usually, architecture of Global IRs is regular, while architecture of Local IRs is more complicated compared to Global IRs. In the paper, a generic IR model rev...

In this paper, a new scheme is proposed to allow the correspondent node to recognize the handover situation of the mobile node for vertical handovers using Mobile IPv6 signaling. The proposed scheme might be helpful for quick adjusting real-time traffics between two nodes when a drastic change in a bandwidth occurs due to vertical handovers in heterogeneous access networks that have a quite dif...

Executive Summary The iSCSI Extensions for RDMA (iSER) protocol is a translation layer for operating iSCSI over RDMA transports, such as iWARP/Ethernet or InfiniBand. This paper presents iSER performance results comparing iWARP RDMA over 40Gb Ethernet and FDR InfiniBand (IB). The results demonstrate that iSER over Chelsio’s iWARP RDMA adapters achieves consistently superior results in throughpu...

Using Architecture and CAD Interactions Benjamin Tseng, Jonathan Rose, Stephen Brown Department of Electrical Engineering, University of Toronto, Ontario, Canada Abstract This paper examines the interactions between the CAD tools that are used to con gure an FPGA's routing resources and the design of the routing architecture itself. Such an understanding is used to determine where to reduce the...
