We derive the elastic properties of a cylindrical cloak for in-plane coupled shear and pressure waves. The cloak is characterized by a rank 4 elasticity tensor with 16 spatially varying entries which are deduced from a geometric transform. Remarkably, the Navier equations retain their form under this transform, which is generally untrue [Milton et al., New J. Phys. 8, 248 (2006)]. We numericall...

The controllability theory may at times lead to a control law as can be seen in the control theory literature. In this paper, a global control algorithm is proposed for nonlinear systems in the so-called linear-analytic form in the plane. The algorithm is motivated by a theorem by Hunt, which gives sufficient conditions for the global controllability of linearanalytic systems on a 2-dimensional...

The Domain Name System (DNS) [7] provides vital mapping services for the Internet. It maps domain names such as ucla.edu to values ranging from IP addresses to email servers to geographic locations and more. Virtually every Internet application relies on looking up some form of DNS data. This article first describes a dichotomy that exists between DNS’ well structured and ordered data plane (th...

The last decade has seen a deluge of proposals for supporting multicast in the Internet. These proposals can be categorized as either infrastructure-based, with the multicast functionality provided by specialized network nodes, or host-based, with the multicast functionality provided by the members of the multicast group itself. In this paper, we present the design and evaluation of a hybrid mu...

Control Plane Design and Performance Analysis for Optical Multicast-Capable Datacenter Networks

Introduction: Pulsed continuous arterial spin labeling (PCASL) was developed to provide improved label and control efficiencies and reduced RF dose compared to multi-slice CASL with a double adiabatic inversion (DAI) control, thus allowing PCASL to be used at high fields (1, 2). However, PCASL is susceptible to label and control plane aliasing and other artifacts related to the design of its la...

This paper describes Mirador, a dynamic placement service implemented as part of an enterprise scale-out storage product. Mirador is able to encode multidimensional placement goals relating to the performance, failure response, and workload adaptation of the storage system. Using approaches from dynamic constraint satisfaction, Mirador migrates both data and client network connections in order ...

Previous techniques for the management and control of optical transport networks are proving inadequate in today’s rapidly evolving multivendor environments. This article examines the issues and challenges involved in developing a standardized optical network control plane. The control of optical transport networks is decomposed into provisioning models, a circuit provisioning process based on ...

Software Defined Networking (SDN) defines a network architecture in which the control plane is managed by a logically centralized controller, and thus configuration updates occur frequently. We have recently introduced an approach that uses time-based configuration updates, allowing to simplify complex update procedures and to minimize transient effects caused by configuration changes. This pap...

The proposed 3GPP’s 5G Next-generation (NextGen) Core architecture (5GC) enables the ability to introduce new user and control plane functions within the context of network slicing to allow greater flexibility in handling of heterogeneous devices and applications. In this paper, we discuss the integration of such architecture with future networking technologies by focusing on the information ce...
