NEXOF-RA • FP7-216446 • D7.1c • Version 1.0, dated 09/12/2009 • Page 1 of 191 Change History Version Date Status Author (Partner) Description 1.0 09/12/2009 Final All Partners This document is a restructured and extended survey of the previous version of the deliverable NEXOF-RA • FP7-216446 • D7.1c • Version 1.0, dated 09/12/2009 • Page 2 of 191 EXECUTIVE SUMMARY One of the main objectives of NEXOF-RA is to produce the NEXOF Open Reference Architecture Specifications. The Architecture Specifications should integrate concepts from existing standards, models, architectures and extend and refine them. The goal of this document is to provide a structured survey of the state of the art to take a census of the most relevant service oriented architecture model/specification, standards and initiatives highlighting their strength and weakness. This survey aims to be as most exhaustive as possible with respect to the completeness of the existing standards and initiatives, even though it do not aims to provide a deep analysis for each of them. A detailed evaluation of the pros and cons of some standards and initiatives investigated in this state of the art will be performed in an afterwards phase only for the initiatives and standards that will be adopted by NEXOF-RA. This state of the art will be constantly updated to bear the rapid changes of the market and to envisage incoming standards and initiatives. To achieve this goal a world wide open process will be set up and maintained through the NEXOF web site. The open process aims to gather the recommendations coming from contributors, both internal contributors like NESSI Strategic Projects and external contributors not directly involved in the NESSI initiatives, to be apprised of the new standards and initiatives of interest for NEXOF-RA. This document is structured in three main parts. The first part focuses on the contribution from the Conceptual View analysis, performed within the project, of the architecture of NEXOF Compliant Infrastructure covering all areas of functionality that are required to support the successful implementation of SOA-based applications. Then, the standards investigated in the state of the art are categorized with respect to each area of functionality. The categorization highlights which standard is of interest for each area of functionality. The second part concerns all general aspects of a SOA and analyses some existing reference architecture models and specifications. The third part focuses on the census of the standards and initiatives surveyed in this state of the art report. An appendix to this document lists all the standards and initiatives that NEXOF-RA is aware of, but which are not included in the census performed in the third part of this document.

With the upcoming 5G, this closed firmware stack has created several tech- nology and business problems. The major problems are hardware-software vendor lock-in, long lead time for feature development and bug fixing, and security risks. The objective of this study is to evaluate the possibility to bring an Open Source software stack for platform management system and baseboard management controller in Telco cloud. The study was divided into 3 parts. First part is to analyse the current state and project specification. Second part is to introduce and evaluate the OpenBMC, an open source soft- ware stack for the objective of this study. Third part is Proof of Concept to run OpenBMC on Telco.

  • History of Manageability
    Chapter 2 History of Manageability Civilizations in decline are consistently characterized by a tendency to- wards standardization and uniformity — Arnold Toynbee (1889–1975) anageability, as a unique discipline, has historically evolved from the M growing need to configure and maintain the computer systems, applications, and networks. As more and more of these entities provided capabilities that could be adapted, changed, and optimized for a particular use or preference, the need for manageability grew. With a low number of systems, it was possible to have system administrators individually log into the system locally and manage each system independently. However, as these systems grew in number and became more and more complex, administrators needed to manage a large number of resources from a central management site. The use of remote management tools became important. This led to development of several protocols for remote management. In the beginning, most of these were proprietary in nature, which meant that a system from one manufacturer could only be managed with a manage- ment console from the same manufacturer. This led the industry to work on interoperable standards that allow the systems from multiple manufactures to be managed with common tools. 15 16 Active Platform Management Demystified Chapter 2: History of Manageability 17 Protocol and Data Model Remote management interfaces can be logically viewed as a combination of a communication protocol and the payload that is exchanged via that communication protocol. Historically, this separation has not always been very clear or emphasized, and some standards have treated them with a very tight binding. However, making this logical separation has clear advantages as illustrated in Figure 2.1.

  • Out of Band Based Remote Management Using Dmtf Specifications
    OUT OF BAND BASED REMOTE MANAGEMENT USING DMTF SPECIFICATIONS 1NILESH PAWAR, 2SANDHYA S., 3CAUVERY N. K 1M.Tech-Student, 2Assistant Professor, 3Professor & HOD, CSE, RVCE Abstract - This paper presents a review on the solution for out of band based remote management using Distributed Management Task Force (DMTF) specifications. DMTF provides a standard for secure remote management, including out- of-band management, of desktop systems. DMTF defines standards that support interoperability among system management tools and managed computer systems. Desktop Management Interface (DMI), Common Information Model (CIM) and Alert Standard Format [5] (ASF) are some of the specifications provided by the DMTF.DMI and CIM interfaces [2] are used for the remote management when theOperating System (OS) is present on client systems. Remote control and alerting interfaces provided by the ASF are used for management when OS not present on client systems. Keywords - DMTF; DMI; CIM; ASF; I. INTRODUCTION 1. Common Information Model (CIM): This model describes the network management DMTF [2] is a non profit organization which provides information. In any organization, basis for the specifications for desktop management.The term management is formed by CIM. “system manageability” represents a wide range of 2. Alert Standard Format (ASF): technologies that enable remotesystem access and ASF is one of the specifications provided by the control in both OS-present and OS-absent DMTF. This specification defines remote control and environments. The main focus of this technology is to alerting interface [5] that are used when the OS is not minimize on-site I/T maintenance and maximize the present on the client.
