End-to-End Network Access Analysis

HPL-2008-28 (R.1) End-to-End Network Access Analysis - Bandhakavi, Sruthi; Bhatt, Sandeep; Okita, Cat; Rao, Prasad
Keyword(s): No keywords available.
Abstract: Network security administrators cannot always accurately tell which end-to-end accesses are permitted within their network, and which ones are not. The problem is that every access is determined by the configurations of multiple, separately administered, components along a path. Furthermore, configu ...

Interference channel capacity region for randomized fixed-composition codes

HPL-2008-194 Interference channel capacity region for randomized fixed-composition codes - Chang, Cheng
Keyword(s): interference channels, randomized coding, capacity region
Abstract: The random coding error exponents are studied [5], [6] for the finite alphabet interference channel (IFC) with two transmitter receiver pairs. The code words are uniform on a fixed-composition set and the decoding is optimum, as opposed to decoding based on interference cancellation, and decoding th ...

TCO-aware provisioning of information security infrastructure

HPL-2008-195 TCO-aware provisioning of information security infrastructure - Robinson, Philip; Stephenson, Bryan
Keyword(s): TCO automated security infrastructure provisioning
Abstract: As IT infrastructure proliferates, higher-level security controls must become interpretable and enforceable by machines, largely without human intervention. We establish a single provisioning model and process for addressing security and the Total Cost of Ownership (TCO). The innovation is the combi ...

Taming Heterogeneous NIC Capabilities for I/O Virtualization

HPL-2008-196 Taming Heterogeneous NIC Capabilities for I/O Virtualization - Santos, Jose Renato; Turner, Yoshio; Mudigonda, Jayaram
Keyword(s): virtualization, I/O, networking, management, configuration
Abstract: The recent emergence of network interface cards (NICs) with diverse hardware features for I/O virtualization poses an important challenge for virtual machine environments, particularly in the area of system management. In this paper, we make the case for developing a high level network I/O virtualiz ...

Using semantics and user participation to customize personalization

HPL-2008-197 Using semantics and user participation to customize personalization - Eynard, Davide
Keyword(s): customization, personalization, semantics, RDF, Web browser
Abstract: Personalization and customization are two techniques that allow systems to provide users an experience which is tailored to their preferences. Looking at the huge success many customization tools had, not just on a particular set of expert users but also on the wide Internet public, we decided to ma ...

Delivering Energy Proportionality with Non Energy-Proportional Systems-Optimizing the Ensemble

HPL-2008-198 Delivering Energy Proportionality with Non Energy-Proportional Systems-Optimizing the Ensemble - Tolia, Niraj; Wang, Zhikui; Marwah, Manish; Bash, Cullen; Ranganathan, Parthasarathy; Zhu, Xiaoyun
Keyword(s): Power, Cooling, Control, Virtualization, Performance, Modeling, VM Migration
Abstract: With power having become a critical issue in the operation of data centers today, there has been an increased push towards the vision of "energy-proportional computing", in which no power is used by idle systems, very low power is used by lightly loaded systems, and proportionately higher power at h ...

Mixed-Initiative Photo Collage Authoring

HPL-2008-199 Mixed-Initiative Photo Collage Authoring - Xiao, Jun; Zhang, Xuemei; Cheatle, Phil; Gao, Yuli; Atkins, C. Brian
Keyword(s): Photo collections, mosaics, image triage, image editing, page layout, constraint satisfaction, user-centered design
Abstract: Creating an artifact that captures the story or memory from a large photo collection is a difficult task, because the tools available are either too difficult to learn, or oversimplified to the point that they lack flexibility. Individual techniques have been developed to automate parts of the selec ...

Detecting Danger: The Dendritic Cell Algorithm

HPL-2008-200 Detecting Danger: The Dendritic Cell Algorithm - Greensmith, Julie; Aickelin, Uwe; Cayzer, Steve
Keyword(s): algorithms, context, computer security, danger
Abstract: The Dendritic Cell Algorithm (DCA) is inspired by the function of the dendritic cells of the human immune system. In nature, dendritic cells are the intrusion detection agents of the human body, policing the tissue and organs for potential invaders in the form of pathogens. In this research, an abst ...
