Explore thought leadership surrounding embedded computing technologies, and gain in-depth knowledge about the industry and open standards trends.
The evolution of networks across generations of evolving protocols has led to a complex mixture of deployed wireless systems. Development towards 5G and the increasing use of heterogeneous networks (HetNets) to improve coverage with fill-in solutions has created an environment of growing complexity, whose management and resource allocation has become a key issue for network operators.
This paper presents the ideas and initiatives driving self-organizing networks (SONs), a key enabler for effective 5G deployment. The authors look closely at the challenge of a data center-based eNodeB pool in a Cloud RAN (C-RAN) context and present a possible solution based on open standard technologies.
The market for embedded computing technologies in rail applications is following a similar trend as has been seen in other embedded market spaces. A layer of the technology value chain becomes ‘table stakes’— delivering limited competitive advantage to a point that it makes sense for application providers to reallocate R&D resources to differentiating elements of the end product and buy the base technology from companies who are dedicated to that technology. We are witnessing this transition in the rail market for embedded computers that are certified to safety integrity level four (SIL4), the highest level. These embedded computers offer a certified, commercial offthe-shelf (COTS) generic fail-safe platform allowing rail application developers to focus their R&D resources on differentiating applications.
A programmable electronic system can be defined as functionally safe if it operates correctly and predictably, so that even in the event of failures it remains safe for persons and the environment. Such a system can be defined as reliable if it performs its function without failure for a specified period of time. These attributes can lead to conflicting requirements and very different designs.
For example, to achieve high levels of functional safety, one method is to compare two or more channels as a diagnostic so that if a difference is detected, the system enters a “fail-safe” state and stops delivering its prescribed service.
The Artesyn MaxCore™ platform offers a versatile and dense architecture to achieve maximum compute and media processing density. Through its use of Artesyn technology microserver cards, Artesyn media processing PCI Express cards and third party PCI Express cards, it offers maximum flexibility, maximum density per rack unit (RU), and unmatched innovation in design for both datacenter and carrier grade applications.
This white paper will spell out the benefits of the MaxCore platform and explain how it is explicitly designed to meet the challenges of the emerging NFV/SDN era. The paper will examine how the MaxCore chassis is superior to others in its power, versatility, flexibility and efficiency.
Looking to reduce costs, improve efficiency, and speed deployment of new services, communications service providers (CSPs) are exploring network functions virtualization (NFV). Suitable for many data plane packet processing and control plane functions in fixed and mobile network infrastructures, NFV implements network functions in software. These virtualized functions can then be instantiated wherever needed in the network without the cost of installing and maintaining new equipment.
Many large-scale cloud providers and data centers are already using virtualization and software-defined networking (SDN) to consolidate functions traditionally hosted on proprietary hardware appliances onto high volume commercial off-the-shelf (COTS) servers, switches and storage. However, this “white box” approach does not work for CSPs. Traditional COTS servers are not designed to handle the high demands of CSP network traffic, nor do COTS servers meet the meet the industry’s high standards for reliability, regulatory and safety compliance, and business continuity.
In this eBook, we look at why the best NFV COTS platform for CSPs currently is ATCA. We also look at ways to optimize ATCA solutions to provide the best performance for NFV.
The extensive use of virtualized environments by data centers and cloud providers has communications service providers (CSPs) looking into ways to use virtualization and cloud technologies to reduce costs, increase efficiency, and improve service agility. For CSPs, such a shift requires a carefully orchestrated transition from the dedicated network appliances they use today to open systems based on more economical commercial off-the-shelf (COTS) servers and open software solutions.
Having different requirements than large-scale cloud providers and data centers complicates this transition. To implement new networking solutions such as network functions virtualization (NFV) and software-defined networking (SDN), CSPs must ensure that the core hardware platforms they deploy deliver the performance, reliability, serviceability, and regulatory and safety compliance their industry requires.
Artesyn is a long-time global leader in providing open platforms for networking equipment. More than 25,000 Artesyn systems and a quarter million Artesyn blades are deployed in mobile and fixed networks globally. To help meet CSP needs for open solutions, Artesyn is taking a leadership position within the Open Compute Project (OCP) and European Telecommunications Standards Institute (ETSI) on developing standardized architectures for network equipment.
Artesyn has always embraced open ecosystems and over the last 15 years has been instrumental in promoting a variety of open standards including VME, cPCI, ATCA, and others. In this paper, we explore how Open Compute technologies and open “white box” hardware offer great promise for CSPs. We also consider the challenges the industry faces in making these technologies viable for the communications services industry.
Broadcast network operators and communications service providers have to make digital video broadcasting meet a number of contradicting requirements in order to maintain its growth trajectory and monetize the associated traffic. The main contradiction lies in the simple fact that the underlying technology is based on a point-to-point technology trying to mimic one-to-many broadcast technology.
However, broadcasting via IP networks can offer significant advantages as well as the ability to provide additional services around the actual broadcast, allowing access to extended, new customer groups and new audiences.
This white paper outlines the technical challenges facing video over IP business models and the associated issue of intellectual property protection, discusses possible solutions, and offers a route to success in this dynamic and fast-changing market.
This white paper discusses the bandwidth challenges being experienced by service providers and explains why data traffic will continue to grow. It goes on to discuss the benefits of using an AdvancedTCA® (or ATCA®) platform for telecom and other high availability applications and explains two approaches to increasing ATCA platform capacity.
It concludes with an overview of the Artesyn Centellis™ platform and explains how it can be used to support up to 1.6Tbps aggregate data bandwidth today and up to 4.0Tbps in the future using the same chassis and backplane for applications such as deep packet inspection, security, packet classification and load balancing.
The increasing density and high-quality processing demands from video applications is pushing broadcast and communications networks to the limit. Adding more equipment to handle these video streams is not economically viable. What's more, operators, service providers and content providers see the benefits of using standard servers in the cloud, and want to move away from special appliances or dedicated hardware. But standard servers currently are not optimized for video transcoding in the cloud.
Cost-Effective Deployment of High-Quality Video Processing for Broadcast Using Off-the-Shelf Technology
This white paper outlines the trends driving the need for high-quality video transcoding and encoding and offers an alternative to conventional host media processing (HMP). Using a PCI Express video accelerator and embedded broadcast video processing firmware, this approach offers dramatically improved performance, taking up less space, consuming less power and costing less. Furthermore, it shows how you can achieve that level of flexibility in a server-based environment. Specific application examples demonstrate the performance and cost virtues of this approach.
The Advanced Telecom Computing Architecture (AdvancedTCA® or ATCA®) is a series of open standard computing platform specifications originally developed to meet the needs of carrier grade communications equipment. It has recently expanded its reach into scientific research, more ruggedized applications geared toward the military and aerospace industries and other industries that require high performance embedded computing. This white paper gives an introduction to the standard covering mechanical characteristics, hardware platform management, and data transport. It goes on to discuss open system management standards that have developed on top of the ATCA specification and concludes with a view to the future for ATCA.
The compact and power-efficient design with moderate ruggedness of ATCA® technology now makes it the ideal choice for military, aerospace and security equipment makers. This paper addresses the forces driving the requirements of high performance embedded computing (HPEC) for military and aerospace applications, including the modular open system approach (MOSA), commercial-off-the-shelf (COTS), and reduced size, weight, power and cost (SWaP-C) as it applies to ATCA.
Traditional methods of digital signal processing in military and aerospace applications have used specialized FPGAs, multiprocessor VME or OpenVPX solutions. Advances in microprocessor technology and accompanying software could mean that AdvancedTCA® (ATCA®) has the potential to replace some of those elements in complex signal processing applications.
Deep packet inspection (DPI) is a technique with many different use cases, delivering information about packet flows and content as well as allowing network operators and service providers to ensure quality of service at an application level.
High density voice and video processing is increasingly in demand for applications such as session border controllers, media gateways/servers or media resource functions, video or content optimization, video communications servers, and interactive voice and video response systems.
Achieving Critical Advantage Through Optimized Media Processing Applications Based on ATCA® Technology
Our thirst for rich multimedia experiences without boundaries on an endless variety of devices continues to grow unquenched. Therefore, the ability to manipulate media streams in carrier networks has become a source of critical advantage to network operators and service providers.
