Method and apparatus for updating system software for a plurality of data processing units in a communication network

Abstract: In maintaining a communication network of processing units distributed in multiple nodes linked by communication channels, system software in a plurality of data processing units is updated by first installing the updated software in a first node. The updated software is transmitted through the network to other nodes. A trial use of the updated software is initiated in the nodes. If failures of the updated software are detected in a node, that node will be restored to the original software version. If the trial use of the updated software is completed successfully in a node, the updated version will be installed as a preferred operational version in the node. a

Inventory management-based computer vulnerability resolution system

Abstract: A remediation server, downloadable software and an associated method for protecting a computer network from vulnerabilities Software in the form of at least one network protection module is downloaded to the remediation server for the computer network and executed to protect the computer network from vulnerabilities Upon execution thereof, the network protection module queries a device inventory for the computer network which is maintained at the remediation server to determine if any devices of a specified device type reside on the computer network For each such device determined to reside on the computer network, the network protection module subsequently resolves vulnerabilities for the device using a remediation signature associated with the device query

Method and system for downloading updates

Abstract: Embodiments of the present invention provide the ability for a software provider to distribute software updates to several different recipients utilizing a peer-to-peer environment. The invention described herein may be used to update any type of software, including, but not limited to, operating software, programming software, anti-virus software, database software, etc. The use of a peer-to-peer environment with added security provides the ability to minimize download time for each peer and also reduce the amount of egress bandwidth that must be provided by the software provider to enable recipients (peers) to obtain the update.

Software Language Engineering: Creating Domain-Specific Languages Using Metamodels

Abstract: Software practitioners are rapidly discovering the immense value of Domain-Specific Languages (DSLs) in solving problems within clearly definable problem domains. Developers are applying DSLs to improve productivity and quality in a wide range of areas, such as finance, combat simulation, macro scripting, image generation, and more. But until now, there have been few practical resources that explain how DSLs work and how to construct them for optimal use. Software Language Engineering fills that need. Written by expert DSL consultant Anneke Kleppe, this is the first comprehensive guide to successful DSL design. Kleppe systematically introduces and explains every ingredient of an effective language specification, including its description of concepts, how those concepts are denoted, and what those concepts mean in relation to the problem domain. Kleppe carefully illuminates good design strategy, showing how to maximize the flexibility of the languages you create. She also demonstrates powerful techniques for creating new DSLs that cooperate well with general-purpose languages and leverage their power. Completely tool-independent, this book can serve as the primary resource for readers using Microsoft DSL tools, the Eclipse Modeling Framework, openArchitectureWare, or any other DSL toolset. It contains multiple examples, an illustrative running case study, and insights and background information drawn from Kleppes leading-edge work as a DSL researcher. Specific topics covered include Discovering the types of problems that DSLs can solve, and when to use them Comparing DSLs with general-purpose languages, frameworks, APIs, and other approaches Understanding the roles and tools available to language users and engineers Creating each component of a DSL specification Modeling both concrete and abstract syntax Understanding and describing language semantics Defining textual and visual languages based on object-oriented metamodeling and graph transformations Using metamodels and associated tools to generate grammars Integrating object-oriented modeling with graph theory Building code generators for new languages Supporting multilanguage models and programs This book provides software engineers with all the guidance they need to create DSLs that solve real problems more rapidly, and with higher-quality code.

COVAMOF: A framework for modeling variability in software product families

Abstract: A key aspect of variability management in software product families is the explicit representation of the variability. Experiences at several industrial software development companies have shown that a software variability model should do four things: (1) uniformly represent variation points as first-class entities in all abstraction layers (ranging from features to code), (2) allow for the hierarchical organization of the variability, (3) allow for the first-class representation of simple (i.e., one-to-one) and complex (i.e., n-to-m) dependencies, and (4) allow for modeling the relations between dependencies. Existing variability modeling approaches support the first two requirements, but lack support for the latter two. The contribution of this paper is a framework for variability modeling-COVAMOF-that provides support for all four requirements.
