Complex software based embedded systems need manageability, high availability, and robustness. The middleware requirements range from simple system level communication and debug, to system HW/SW health monitoring, to support for external operations management systems, and up to high availability and/or robust fault management. The middleware must also support a wide range of HW platforms from simple SoCs, single boards, big chassis-based systems, rack mount servers, and Cloud-based platforms.

Distributed systems range from simple multi-threaded applications to multi-slot chassis-based systems to networked clusters of servers. Topologies get more complex when these systems move into cloud-based environments, and more diverse when they involve machine-to-machine (or M2M) solutions. Providers of distributed system software solutions face a number of challenges in building, debugging and maintaining a set of connected applications. Managing these systems requires powerful modeling and a variety of management interfaces to meet a diverse set of needs. The services provided by a distributed system often require a high level of availability. The middleware frameworks that make up Enea Element address many of these challenges.

Minimize footprint to maximize value! The emergence of lower-cost, high-volume white boxes along with standardized software APIs is a fundamental change that increases supplier choice and reduces cost for uCPE. Virtualization platforms with open, scalable and optimized software enable lower hardware costs since fewer cores and less memory are needed to deliver the necessary performance. For effective service creation, CSPs must consider the necessary latency, throughput/performance and resiliency for their applications or services, and ensure that they are easily managed and orchestrated. Operational considerations such as zero-touch provisioning, platform and VNF management does also have an impact on cost and thus need to be optimized. Value-adding capabilities enabled by deep packet inspection (DPI) like service function chaining (SFC) and dynamic traffic management are also key ingredients in an optimized solution.

Technical paper "Choosing Your Runtime"

Download

Linux is designed for general throughput processing rather than real-time, and consequently it needs to be modified or complemented to meet high demands on interrupt latency, determinism and low-overhead multitasking. In parallel, the evolution towards multi- and manycore devices challenges Linux in terms of its capability to provide a cost-efficient and real-time capable OS platform, and therefore we need to constantly evaluate our alternatives to enable real-time acceleration in Linux. This whitepaper describes the challenges and discusses three different options for how to enable real-time in Linux.

As hardware has become ever more capable there has been a trend to implement real-time applications on Linux. Linux was designed from the beginning for server and desktop applications, not for real-time applications. This means that achieving real-time properties on Linux is not trivial. This document is a guide for anyone attempting to implement a real-time application using Linux.

Virtualization of network appliances, using software implementations running in virtual machines, allows the usage of cost-efficient data center solutions as possible replacements for proprietary hardware. In order to maintain fulfilment of requirements on high speed network communication, efficient virtualization is required, affecting the virtual machine host as well as its guests. To speed up communication, the use of user space access to network I/O in host and guest is becoming more and more popular. This document presents performance benchmark results for a selection of recent solutions for high speed network I/O in user space host, and guest applications in a virtual machine. The paper compares the host and guest throughput performance, using stateof-the-art benchmarks and measurement methods.

This paper starts by describing the widely accepted multiprocessing software design models, and some of their benefits and drawbacks. After that, a few simple packet processing use cases are described, aiming to illuminate the pain points of a strict AMP multiprocessing approach. Finally, we introduce Enea’s OSE Multicore Edition (OSE MCE), and show how this new hybrid SMP/AMP RTOS technology can provide a homogeneous, scalable and portable execution platform for high-performance protocol processing for example within the LTE layer 1 and 2, while at the same time being a feature-rich SMP RTOS capable of network O&M. OSE MCE defines a very low-level multicore processor abstraction model which gives high portability and at the same time it provides a low-overhead device programming model.
