Executives from Telco Systems’ research and development (R&D) centers in Israel and Poland made several presentations during the last Ciklum Gdansk Cloud Meetup, which focused on cloud edge technologies and took place on July 31, 2018 in Gdansk, Poland.
The first speaker was Paweł Koniszewski, network functions virtualization (NFV) infrastructure developer at Telco Systems, whose presentation dealt with rolling upgrades and was based on an OpenStack case study.
Koniszewki explained that any application, regardless of whether it is distributed or not, should ideally reach 100 percent service-level agreement (SLA). To achieve that, all environments need to be highly available with appropriate redundancy. He added that operations such as operating system or software upgrades need to be considered as well. He also described different approaches to preparing distributed applications to support live upgrades between versions based on OpenStack experience.
This was followed by a presentation from Dawid Deja, NFV Infrastructure developer at Telco Systems, who spoke on the topics of network functions (NF) and life cycle management (LCM), using Tacker. During the presentation, Deja demonstrated how to install and use OpenStack Tacker to make virtual network functions (VNF) management easier.
The last presentation was given by Stanislav Elenkrich, SW & Architecture Group leader at Telco Systems. The talk, entitled “NFV Edge Acceleration technologies using ARM based architecture” showcased high-level architecture for the ARM-based system on chip (SoC) acceleration mechanism. Elenkrich also shared performance results for proposed architecture while using real use cases.
He said that the true gain of NFV for carrier service providers (CSPs) comes from much faster adaptation and deployment. This enables providers to address customer needs significantly faster, while keeping in force the carrier grade nature of those services.
He pointed out that as the universal customer premises equipment (uCPE) device resources on the edge are limited the networking and security performance becomes an important aspect.
Elenkrich added that performance improvement on top of SW acceleration (DPDK/SRIOV) may be reached by HW acceleration (FPGA, NPU, embedded SoC accelerator).
He said that among the important benefits that can be gained from ARM-based SoCs are embedded HW accelerators for forwarding plane and security operations. This enables the building of smart, high performance and cost-effective NFV infrastructure, which can serve both uCPE host operating system (OS) and virtual machine (VM) which incorporate proper drivers to support it.
