• • Fundamentals of Multicore: Operating Systems for Telecom/Networking Applications

    This white paper provides a “tutorial like” overview of the fundamental issues that apply to multicore software operating systems implementation for the telecom/networking space.

  • The Shortest Path to Embedded Linux Deployment

    The GNU/Linux operating system has a long history of dissemination in the form of “distributions” – aggregations of the Linux kernel, GNU libraries, utilities and tools, and selected other software. These distributions historically targeted workstations and servers, and more recently expanded to embedded and mobile development toolkits.

  • Android: Opportunities and Challenges

    The emergence of Android paves the way for new opportunities for the world’s mobile phone manufacturers to take advantage of the trend created by Apple with its iPhone, moving the user back to the center.

  • Deploying Multi-Technology, Multi-Vendor Communications Platforms

    Developing and deploying communications equipment is not getting any easier.Economic and competitive pressures continue to demand that network equipment be deployed with more revenue generating functionality– faster and at a lower cost.

  • The Architectural Advantages of OSE in Telecom

    The days are long gone when a real-time operating system (RT OS) was simply a small kernel providing basic services such as task scheduling and reliable inter-task communications. Today’s real-time operating systems are expected to perform a wide variety of functions ranging from managing real-time communications to providing a reliable foundation for higher level applications.

  • Maximizing Utilization of Digital Signaling Processors

    Pressure from service providers is being exerted on telecommunications equipment manufactures (TEMs) to build the network elements that will power this major evolution in communications. The question for the TEMs is: “How do you lower the cost per channel while lowering the cost of the equipment?”

  • The Middleware Factor in Rapid Services Deployment in Next-Generation Networks

    As the migration to “all-IP” next-generation networks continues, this trend has fundamentally transformed the Service Provider (SP) landscape, presenting numerous opportunities to offer exciting new services. But with intense competition from all sides, and from new players, this has also brought challenges in agility, network operational efficiency and lifecycle management, while struggling to maintain the profitability and reliability that the SPs had achieved with legacy networks.

  • Multicore: High performance packet processing enabled with a hybrid SMP/AMP OS technology

    Moore’s law does still hold, but processor vendors are rapidly turning to use the additional transistors to create more cores on the same die instead of increasing frequency since this not only gives more chip performance but also decreases the power consumption (watt/mips).

  • Polyhedra IMDB and High-Availability

    Integrated data management services are an integral part of any advanced network equipment software platform. Where large application-level data storage is required, the data management solution may come in the form of a traditional disk-based relational database management system (RDBMS).Many network infrastructure systems, however, require a separate, higher performance, in-memory database solution.

  • Changing the way Managed ATCA Platforms are Delivered to the Market

    There is no doubt the emergence of commercial off the shelf (COTS) hardware platforms, Carrier Grade Linux, and management middleware have had a significant impact on the market for next generation network equipment. By enabling Telecom Equipment Manufacturers (TEMs) to readily assemble best of breed COTS components, a ’jumpstart’ on the development of new Network Elements can be realized. But having standardized COTS building blocks is only a part of the puzzle.

  • Protocol operations in telecommunication gateways

    Gateway. It is one of the most widely used terms in the telecommunications industry. It designates a wide variety of systems or functions that enable communications between two parties that cannot be connected in a direct way either for technical, management or administrative reasons. The parties in question can be a host system and a network, two networks or two elements in the same network.

  • Closing the Service Availability Gap – Updating software in a live system without loss of service

    The ability to upgrade or patch complex system software without disrupting service is an absolute requirement in today’s highly connected world. Yet it remains one of the most elusive features for today’s high-availability middleware offerings.

  • Multi-core Applications in Telecom

    This document provides an overview of multi-core technology addressing such issues as the motivation for multi-core, and applications for multi-core in telecom. Following this, some more specifics on implementation alternatives are addressed, and these alternatives then affect the design choices for different types of telecom applications. Virtualization technology, once the domain of single CPU’s now finds some applicability in the multi-core space.

  • System level debugging: A Means to Achieve Holistic Debugging

    In a world of computers with ever increasing complexity and pervasiveness, there is an increasing need for debugging methods that can tackle system level faults, where reproducibility and observability of multiple interacting programs and subsystems can be dealt with holistically, and where in field debugging is as important as predeployment debugging.

  • Leveraging the Enea dSPEED Platform to Achieve Highly Available User Plane Processing

    Market pressures demand that each new generation of networking and communications system deliver both higher performance and new functionality at a lower price. In many applications, the ability to provide continuous operation, even in the presence of failures (also known as high-availability), is a key customer requirement.
