Existing multicast group management solutions fall short of providing adequate support for secure group integrity maintenance. This is especially true in the multimedia context, where, on top of intra-group integrity, intergroup (i.e. inter-media) considerations have to be taken into account. We demonstrate, along a comprehensive example, the applicability of our integrity framework for multica...

In this paper, we argue that recent device hardware trends enable a new approach to the design of operating systems: instead of the operating system mediating access to hardware, applications run directly on top of virtualized I/O devices, where the kernel provides only control plane services. This new division of labor is transparent to the user, except that applications are able to offer more...

The Internet transport infrastructure is moving towards a model of high-speed routers interconnected by optical core networks. The architectural choices for the interaction between IP and optical network layers, specifically, the routing and signaling aspects, are maturing. At the same time, a consensus has emerged in the industry on utilizing IP-based protocols for the optical control plane. T...

in this paper, distributed parameter process systems behavior is studied in frequency domain. based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. by using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

background: excessive lumbar vertebrae translation and rotation in sagittal plane has been attributed as an associated factor of lumbar segmental instability (lsi) and low back pain (lbp). reduction of these abnormalities improves back pain. the aim of this study was to investigate the effect of core stability exercise on the translation and rotation of lumbar vertebrae in sagittal plane in pat...

The multi-radio access architecture within the ambient network concept opens up opportunities for new business roles within the mobile and wireless domain. The new business roles take advantage of the control plane functionality that enables cost efficient connectivity over heterogeneous radio access technologies. Index Terms — Multi Radio Access, cost efficient, new business roles

As Internet video goes mainstream, we see increasing user expectations for higher video quality and new global policy requirements for content providers. Inspired by the case for centralizing network-layer control, we present C3, a control system for optimizing Internet video delivery. The design of C3 addresses key challenges in ensuring scalability and tackling data plane heterogeneity. First...

Many cooperative overlay multicast systems of diverse designs have been implemented and deployed. In this paper, we explore a new architecture for overlay multicast: we factor out the control plane into a separate overlay that provides a single primitive: a configurable anycast for peer selection. This separation of control and data overlays has several advantages. Data overlays can be optimize...

The Bring-Your-Own-Handheld-device (BYOH) phenomenon continues to make inroads as more people bring their own handheld devices to work or school. While convenient to device owners, this trend presents novel management challenges to network administrators as they have no control over these devices and no solid understanding of the behavior of these emerging devices. In order to cope with the imp...
