  • Carrier Grade Virtualization
    Carrier Grade Virtualization Leveraging virtualization in Carrier Grade Systems Abstract Network Equipment Providers (NEPs) have been building networking infrastructure equipment able to deliver “carrier grade” services, typically mission-critical services such as voice telephony. In decades past, NEPs have achieved high degrees of availability through purpose-built hardware and software implementations. Today they increasingly build on COTS (Commercial Off The Shelf) hardware and Open Source Software (OSS), freeing their engineering resources to focus on core telephony competencies. The move to COTS and OSS requires that these hardware and software components be available from an ecosystem of suppliers, and that they interoperate seamlessly. Bodies such as The Linux Foundation (LF), the Service Availability Forum (SA Forum) and PICMG have defined standards and specifications such as carrier grade OSes (CGLinux), Service Availability Forum APIs and AdvancedTCA hardware to target carrier grade applications. Recent advances have made virtualization appealing for carrier class equipment by permitting significant cost reduction through consolidation of workloads and of physical hardware. Virtualization also transparently lets NEPs and other OEMs (Original Equipment Manufacturers) leverage multi-core processors to run legacy software designed for uniprocessor hardware. However, virtualization needs to meet specific requirements to enable network equipment deploying this technology to meet industry expectations for carrier grade systems. This

Vesa Hirvisalo Modern embedded devices, such as smartphones, have grown into complex computer systems that provide a rich set of functionality for their users while still maintain- ing real-time responsiveness for their low level functions such as radio communication or camera control. The embedded market is very competitive, especially in end-user mobile devices, making it desirable to reduce manufacturing costs without compromis- ing device performance wherever possible. The ever-growing user demand for more computing-intensive applications coupled with tight energy budgets has led the em- bedded manufacturers to seek performance gains from multi-core architectures, much like their desktop counterparts. However, multi-core architectures have little to provide in performance gains when used with applications developed with traditional software design methods that are aimed at single-core archictures.

  • Virtualization – the Power and Limitations for Military Embedded Systems – a Structured Decision Approach
    2010 NDIA GROUND VEHICLE SYSTEMS ENGINEERING AND TECHNOLOGY SYMPOSIUM VEHICLE ELECTRONICS & ARCHITECTURE (VEA) MINI-SYMPOSIUM AUGUST 17-19, 2010 DEARBORN, MICHIGAN VIRTUALIZATION – THE POWER AND LIMITATIONS FOR MILITARY EMBEDDED SYSTEMS – A STRUCTURED DECISION APPROACH Mike Korzenowski Vehicle Infrastructure Software General Dynamics Land Systems Sterling Heights, MI ABSTRACT Virtualization is becoming an important technology for military embedded systems. The advantages to using virtualization start with its ability to facilitate porting to new hardware designs or integrating new software and applications onto existing platforms. Virtualization is a tool to reuse existing legacy software on new hardware and to combine new features alongside existing proven software. For embedded systems, especially critical components of military systems, virtualization techniques must have the ability to meet performance requirements when running application software in a virtual environment. Together, these needs define the key factors driving the development of hypervisor products for the embedded market: a desire to support and preserve legacy code, software that has been field-proven and tested over years of use; and a need to ensure that real-time performance is not compromised. Embedded-systems developers need to understand the power and limitations of virtualization. This paper presents virtualization technologies and its application to embedded systems. With the dominant market of multi-core processing systems, the need for performing specific hardware/software configuration and usages with relations to Platform Virtualization is becoming more and more prevalent. This paper will discuss different architectures, with security being emphasized to overcome challenges, through the use of a structures decision matrix. This matrix will cover the best suited technology to perform a specific function or use-case for a particular architecture chosen.

  • Software and Hardware Supports for Multi-OS Environment
    Software and Hardware Supports for Multi-OS Environment マルチ OS 環境を支援するソフトウェア およびハードウェア機能の提案 February 2012 Waseda University Graduate School of Fundamental Science and Engineering Major in Computer Science and Engineering Research on Distributed Systems Yuki KINEBUCHI 2 c Copyright by Yuki Kinebuchi 2012 All rights reserved 2 Acknowledgements This is a great opportunity to express my respect to my thesis advisor, Prof. Tatsuo Nakajima. My research and this dissertation would not exist without his support and patience. I would also like to thank all the members at Distributed Computing Laboratory in Waseda University for encouraging me. 3 4 Abstract Personal mobile devices are rapidly enhancing their functionalities. Not limited to phone and text messages, they offer web browsing via the Internet, free to install applications on the users’ requests, play musics and videos, etc. Now they are capable of running multiple OS instances with support of virtualization. Like the use in desktop/enterprise systems, virtualization for embedded mobile devices allows consolidating multiple OS instances and enhancing the security of hosted OS environment. In addition, there are applications specific to embedded systems such as hosting real-time OS (RTOS) and application OS (GPOS) concurrently without spoiling the real-time responsiveness of the RTOS. There is no doubt that virtualization brings many benefits to the embedded mobile devices, however virtualization is not a panacea. Additional layer of virtualization incurs additional complexity to the software stack of devices. Some extra engineering efforts of developing such device might make the system prone to bugs and security risks. In this dissertation we take the position that some applications of embedded virtualization can be supported with more light-weight methods.
