Linux Software Router: Data Plane Optimization and Performance Evaluation
No full textRecent technological advances provide an excellent opportunity to achieve truly effective results in the field of open Internet devices, also known as Open Routers or ORs. Even though some initiatives have been undertaken over the last few years to investigate ORs and related topics, other extensive areas still require additional investigation. In this contribution we report the results of the in-depth optimization and testing carried out on a PC Open Router architecture based on Linux software and COTS hardware. The main focus of this paper was the forwarding performance evaluation of different OR Linux-based software architectures. This analysis was performed with both external (throughput and latencies) and internal (profiling) measurements. In particular, for the external measurements, a set of RFC2544 compliant tests was also proposed and analyzed

No full textAbstractIn order to overcome the cloud service performance limits, the INPUT Project aims to go beyond the typical IaaS-based service models by moving computing and storage capabilities from the datacenters to the edge network, and consequently moving cloud services closer to the end users. This approach, which is compatible with the concept of fog computing, will exploit Network Functions Virtualization (NFV) and Software Defined Networking (SDN) to support personal cloud services in a more scalable and sustainable way and with innovative added-value capabilities

Abstract
In the last years, networking device architectures based on Open Source Software, like Linux, have aroused lively interest from both Scientific and Industrial Communities. The key to this success can probably be found in the flexibility and fast development time of the Software approach, and the reliability level guaranteed by large communities of users and developers. In this contest, our aim is to customize, to analyze and to optimize a Linux based architecture for an exclusive networking use. In particular, the objective of this work is to study, to evaluate the performance and to optimize the IP lookup mechanism included in the Linux kernel. With this aim we have released a set of kernel patches to enhance the performance of the system by optimizing the IP lookup mechanism. We present a complete set of benchmarking results with both internal and external measurements
Energy-Aware Equipment for Next-Generation Networks
No full textBesides a more widespread sensitivity to ecological issues, the interest in energy-efficient network technologies springs from heavy and critical economic needs, since both energy cost and network electrical requirements show a continuous growth, with an alarming trend over the past years. In this contribution, we explore and try to evaluate the feasibility and the impact of power management mechanisms on network equipment performance. We discuss and characterize how these energy-aware enhancements can be applied inside device architectures working in access and core networks. Finally, we show how a state-of-the-art multi-Core SW Router based on COTS HW can effectively modulate the trade-off between its energy requirements and network performance
