KVM Enhancements for OPNFV
We are working on KVM enhancements for NFV as a collaborative development project in OPNFV, focusing on three key features: minimal Interrupt latency variation, inter-VM (Virtual Machine) communication, and fast live migration. In this presentation, we introduce and provide an update on the project, and how we plan to work with the upstream KVM project.
Minimal Interrupt latency variation is required for data plane VNFs to achieve deterministic execution. We present an update, demonstrating how hardware and software enhancements can help when reducing latency variations.
We evaluate and compare the options for inter-VM communication (e.g. ivshmem, vhost user, VMFUNC, etc.) in terms of performance, interface/API, usability/programing model, security, and maintenance.
Finally we provide and update on fast live migration, including improvements with time to co
Platform Independent Packet Processing with ODL
The Open Dataplane (ODP) provides a platform-independent API and framework for packet processing applications. Especially, it enables applications to use the special packet processing capabilities of system-on-chips without being tied to a specific hardware implementation.

VNFs at the Edge using Docker Containers
While little discussed, there is a solid case in placing some VNFs at the edge of the network, but this notion implies a distributed model that VNFs were not originally created to address. One of the problems in placing VNFs at the network edge is that the edge equipment may be very cost sensitive and in many cases, consumer grade.
These consumer-grade devices cannot support a virtual container such as a KVM because of the huge memory requirements of an additional OS. A Docker container has been proposed and implemented with great success.
Open Source in a Closed Network
In networks built from proprietary and specialized equipment and software, can we really achieve the touted benefits of applying open source?

In this year we have wrestled with many issues on both the development and business front, as we balance CSP expectations vs CSP realities, cooperation vs differentiation, and try to harness the chaotic open source development model to deliver useful software in a timely manner. This talk will provide an overview of the challenges we faced, our learnings and achievements.
Software-defined migration how to migrate bunch of v-ms and volumes within a...
Kentaro Matsumoto, KDDI Corporation, Hyde Sugiyama, Red Hat, Inc
As telecom career, we KDDI have been managing thousands of physical servers and run various kinds of workloads. In our operation of such a huge environment, We are frequently required to shut down our servers for maintenance, but it is not easy to negotiate with our tenant users to allow downtime. To make it easier, we are developing the structure called "Zone Migration", using the framework of OpenStack project "Watcher". "Zone Migration" makes it possible to migrate tenants’ workloads from compute nodes and storage devices we want to maintain (source zone) to new blank ones (destination zone) efficiently, automatically, and with minimum downtime.
These requirements as follows are realized.
-A lot of VMs and volumes should be migrated within a limited time frame
-Operations should be automated, but also can be controlled manually
-Time and load of migration should be under control so that tenants’ systems will not be affected
We are proceeding with the project in cooperation with NEC and Red Hat, and developing this structure on Red Hat OpenStack Platform.

Summit 16: OPNFV on ARM - Hardware Freedom of Choice Has Arrived!
Freedom of choice is one of the key concepts in the SDN and NFV revolution we are seeing today. OPNFV is at the heart of this revolution yet very limited freedom of choice has existed on the hardware architecture side. However, with the work done in the Armband project, ARM servers are now an alternative hardware architecture for Brahmaputra deployments. The Armband team has ported the OPNFV Fuel Project to support deployments on ARM servers. The necessary code changes have been upstreamed through the OPNFV armband project. End users are now able to download or build their own Brahmaputra OPNFV ISO ready for ARM and install it using available OPNFV documentation. In addition to this and to further the OPNFV VNF ecosystem, a full specification OPNFV Pharos lab based on ARM servers was built by Enea for running continuous integration (CI) and continuous deployment (CD). In this presentation, we will walk you through the experiences gained in this process, the challenges and how they were overcome and what is coming next.

Summit 16: OPNFV on ARM - Hardware Freedom of Choice Has Arrived!
Freedom of choice is one of the key concepts in the SDN and NFV revolution we are seeing today. OPNFV is at the heart of this revolution yet very limited freedom of choice has existed on the hardware architecture side. However, with the work done in the Armband project, ARM servers are now an alternative hardware architecture for Brahmaputra deployments. The Armband team has ported the OPNFV Fuel Project to support deployments on ARM servers. The necessary code changes have been upstreamed through the OPNFV armband project. End users are now able to download or build their own Brahmaputra OPNFV ISO ready for ARM and install it using available OPNFV documentation. In addition to this and to further the OPNFV VNF ecosystem, a full specification OPNFV Pharos lab based on ARM servers was built by Enea for running continuous integration (CI) and continuous deployment (CD). In this presentation, we will walk you through the experiences gained in this process, the challenges and how they were overcome and what is coming next.

How to-migrate-and-manage-security-policies-in-a-segmented-data-center---webi...
Network segmentation is an effective strategy for protecting access to key data assets, and impeding the lateral movement of threats and cyber criminals inside your data center. With network virtualization, such as VMware NSX, now a reality it's now far easier and quicker to set up granular security policies for east-west traffic within the data center. Yet the added granularity of securities policies creates significant complexity.
Presented by renowned industry expert Professor Avishai Wool, this technical webinar will provide strategies and best practices to help organizations migrate and manage security policies efficiently within a micro-segmented data center.
During the webinar Professor Wool will cover how to:
· Identify and securely migrate legacy applications to a micro-segmented data center
· Effectively define and enforce security policies for East-West traffic
· Manage the micro-segmented data center alongside traditional on-premise security devices
·Identify risk and manage compliance in a micro-segmented data center
· Use network segmentation to reduce the scope of regulatory audits
· Identify and avoid common network segmentation mistakes

SDN and metrics from the SDOs
This document discusses SDN and metrics from various standards development organizations (SDOs). It notes that many SDOs are developing YANG data models for network automation using model-driven APIs. There is growth in YANG models at the IETF and other SDOs like BBF, IEEE, MEF, and OpenConfig. However, coordination is needed between SDOs to reduce costs as the data models need to work together to create network services. A YANG catalog is proposed to help organize the industry and provide a common inventory of all YANG modules across SDOs and vendors.

VPN - Virtual Private Network
Overview of VPN protocols.
VPNs (Virtual Private Networks) are often viewed from the perspective of security with the goal of providing authentication and confidentiality.
However, the primary purpose of VPNs is to connect 2 topologically separated private networks over a public network (typically the Internet).
VPNs basically hook a network logically into another network so that both appear as one private local network.
Security is a possible add-on to VPNs. In many cases it makes perfectly sense to secure the VPNs communication over the unsecure public network.
VPN protocols typically employ a tunnel where data packets of the local network are encapsulated in an outer protocol for transmission over the public network.
The most important VPN protocols are IPSec, PPTP and L2TP. In recent years SSL/TLS based VPNs such as OpenVPN have gained widespread adoption.
Application-Based Routing
This talks shows how to implement the Application-Based Routing in the common Linux Distribution. We use the NDPI to execute the DPI function to category the packet first, use the linux kernel build-it mark to pass the information from user-space to kernel space and then the policy routing system use that mark to route the packet by different destination or interface.

MPLS L3 VPN Tutorial, by Nurul Islam Roman [APNIC 38]
This document discusses deploying MPLS L3VPN. It begins with an overview of MPLS and VPN terminology. It then covers the MPLS reference architecture and different node types. It describes how IP/VPN technologies use separate routing tables at provider edge (PE) routers to provide independent virtual routing and forwarding (VRF) instances for each VPN customer. The control plane uses multiprotocol BGP (MP-BGP) to distribute VPN routes between PE routers using route distinguisher (RD), route target (RT), and labels. The forwarding plane uses these labels to encapsulate and transport customer IP packets across the MPLS core. The document then discusses various IP/VPN services including load sharing, hub-and-spoke

How to Reuse OPNFV Testing Components in Telco Validation Chain
Morgan Richomme, Orange
OPNFV provides lots of tooling that can be adopted and adapted to Service providers solution. These solutions are OpenStack based but not necessarily OPNFV solutions.
This session will detail how some components developed in OPNFV have been introduced in Orange Integration Center, an OpenStack based vendor solution including Contrail SDN controller and third party elements.
The best practices learned in OPNFV were used to design and build a CI chain including jenkins, functest, yardstick, the test API and the Test DB.
Energy Audit aaS with OPNFV
Morgan Richomme, Orange
Power consumption is a key driver of NFV. However very few projects deal with this aspect.
This session will detail a prototype realized in OPNFV Orange labs aiming to track power consumption during CI operations.
We could imagine that, if we generalize the information colelction to the Pharos community, we may get significative figures to establish power consumption profiles and why not try to get even deeper and get applicative profile using statistical tools
Hands-On Testing: How to Integrate Tests in OPNFV
Jose Lausuch, Ericsson
I have developed and integrated a new feature but… how do I write test cases and where do I put them? How do I start?
These are common questions asked by developers bringing new features that need to be tested and verified in our CI pipeline.
Storage Performance Indicators - Powered by StorPerf and QTIP
Yujun Zhang, ZTE Corporation, Mark Beierl, Dell EMC
StorPerf uses heat to create VMs with attached cinder volumes. The volumes are used *without* a file system (ie target=/dev/vdb). The FIO workload is run and stats collected every minute. When we get 10 samples in a row that fit within a certain range and slope, we say it is a valid measurement. This avoids false numbers due to Ceph balancing or other warm up. The metrics can be read after job completes, and there is an indicator to state if the volume metrics stabilized or not.
Storage QPI will be calculated based on the test results from storperf by QTIP. It aims to be a comparable indicator for storage performance among different platforms.
Big Data for Testing - Heading for Post Process and Analytics
Yujun Zhang, ZTE Corporation, Donald Hunter, Cisco, Trevor Cooper, Intel
The testing community created tens of testing projects, hundreds of testing cases, thousands of testing jobs. Huge amount of testing data has been produced. What comes next, then?
The testing community puts in place tools and procedures to declare testcases/projects, normalize and upload results. These tools and procedures have been adopted so we now have lots of data covering lots of scenarios, hardware, installers.
In this presentation, we shall discuss the stakes and challenges of result post processing.
* How analytics can provide valuable inputs to the community, end users or upstream projects.
* How can we produce accurate indicators, reports and graphs, focus on interpreting / consuming test results.
* How can we get the best of breeds of our result mine?

Being Brave: Deploying OpenStack from Master
Fatih Degirmenci, Ericsson, Yolanda Robla Mota, RedHat, Markos Chandras, SUSE
OPNFV has been working with the communities such as OpenStack, OpenDaylight, and fd.io as part of its Cross Community CI (XCI) effort in order to provide means for the developers to work with the latest versions of upstream components, cutting the time it takes to develop new features significantly and testing them on the OPNFV Infrastructure.
Apart from developing and testing new features, OPNFV XCI will enable developers to identify bugs earlier, issue fixes faster, and get feedback on a daily basis. This is a prerequisite for OPNFV in its CD & DevOps journey.
OPNFV aims to run XCI by reusing what other communities developed such as bifrost and openstack-ansible. While doing this, OPNFV intends to develop, maintain, and evolve OPNFV Infrastructure like how the other OPNFV projects do; upstream first. Whatever missing functionality and issues we identify in the components we use as part of our infrastructure and CI/CD toolchain, we strive to fix them directly upstream.
During this session, we will talk about the progress we have made so far, contributions we made to our upstream communities, and share our experiences. We will also highlight the key benefits of XCI for the community in order for developers to utilize the mechanisms, work with OpenStack master to implement new features and fix bugs using the toolchain XCI established.
Upstream Testing Collaboration
Jose Lausuch, Ericsson
OPNFV provides different test frameworks which help developers to write new test cases. Those frameworks also borrow and integrate a variety of testing tools from other open source communities (OpenStack, OpenDaylight, Open-O, ...).
This session will go through all the tools that have been integrated so far in OPNFV and the cross community collaboration that has already started in Danube time frame.
Enabling Carrier-Grade Availability Within a Cloud Infrastructure
Aaron Smith, Red hat, Pasi Vaananen, Red Hat
Carrier-Grade Cloud Infrastructure (Aaron Smith, Pasi Vaananen, Red Hat): The move from vertically integrated hardware and software to distributed execution in a cloud complicates the delivery of highly available services. Vertically integrated systems enabled all system layers required to communicate and participate in the support of availability of the service to be under control of single system vendor. With NFV, the cloud philosophy of infrastructure and application decoupling requires new open interfaces to support the necessary flow of information between layers and clear separation of the fault and availability management responsibilities between the infrastructure and application SW subsystems. Even in the cloud environment, traditional availability concepts such as fast detection, correlation, and fault notification still apply. A fast, low-latency fault management platform will be presented that allows cloud-based services to achieve 5NINES of availability and service continuity. Performance measurements from a prototype of the system will be presented along with a demo of the operation of a service requiring 50 ms fault remediation.

Distributed vnf management architecture and use-cases
Sridhar Pothuganti, NXP, Trinath Somanchi, NXP
Telco operators are on journey to discover what virtualization means for the network. Markets have believed that NFV architecture elements: NFVI and VIM, hold the complete responsibility in providing virtualized networks with carrier grade properties.
Telco operators have reached to a conclusion that VNFs must take their fair share of responsibility to realize NFV goals while meeting carrier-grade behavior in the entire NFV architecture. While the trend moves on, Cloud native VNFs are emerging best citizens of the cloud. Thus communication from EMS to VNFM is blurred and eventually may disappear in the future. This requires better understanding of, and agreement over the role of VNFMs and EMS for VNFs.
This presentation describes the evolution of Distributed VNF management, Architectural design considerations and Use-case scenarios. The following proposal is based on a comprehensive study on evolving cloud native VNF management.
Securing your nfv and sdn integrated open stack cloud- challenges, use-cases ...
Sridhar Pothuganti, NXP, Trinath Somanchi, NXP
Network security and reliability are the most challenging tasks in any cloud. With NFV and SDN in place, Network Functions are virtualzied and network traffic is managed in separated control and data planes. Thus reducing the operational and capital expenditure. Virtualized Network Functions are tied with Software Defined Networks to boost the power of virtualization. This itself is challenging when Network services and security is a concern. While OpenStack is the best opted solution for IaaS, many service provides are moving towards best solutions to deal with service delivery and security challenges in SDN and NFV integrated OpenStack Cloud.
The Presentation outlines the challenges and proposes probable solutions for NFV and SDN integrated OpenStack Cloud.
My network functions are virtualized, but are they cloud-ready
Ulas Kozat, Huawei, Yaoguang Wang, Huawei
In the first phase of telco-cloud vision, the physical network functions are targeted for virtualization and became Virtual Network Functions (VNF) decoupled from the specific hardware platform. As we dive into the second phase of the cloud era, the core need is to provide VNF implementations that can take advantage of what cloud has to offer in terms of utility based computing (a.k.a. scaling), availability, data durability, etc. To this end, we have been developing a VNF Performance Modeling framework for automatic characterization of a particular VNF implementation in terms of its cloud-readiness and its bottlenecks towards cloud-readiness. We will present the details of our performance modeling framework and show its utility based on the existing open source VNF implementations. The next frontier of telco-cloud vision is to develop cloud-native network functions and services. Thus, in the last part of our talk, we will cover the future evolution of the framework and discuss the needs, requirements, potential metrics for evaluating the cloud-nativeness of network functions.

There are many countries in Asia region those have the motivation to innovate their telecom system and educate new technologies to young engineers. It is important how to encourage and involve these countries to OPNFV communities, and also educate to contribute to open source activities.
In these session, we will introduce our trial to the issue. Okinawa Open Laboratories (OOL) in Japan and Institute for Information Industry (III) in Taiwan, have been doing joint research activities in these years about SDN/NFV area, and this year, we have connected each testbed using OPNFV. Over the distributed testbed, we have started our POC of NFV use cases such as vEPC, vCPE etc. We also have communication with several research and academic organization in Asia region, so we would like to connect each country’s testbed and expand our testbed to Asia region.
There are many challenges, and we have learned from our experience, so in the session we will share the lessons learned from our trial. That will be good example for the whole community, and help progressing collaboration of global eco system.
Accelerated dataplanes integration and deployment
Tim Rozet, Red Hat, Feng Pan, Red Hat
This session will explore the challenges and lessons learned with integrating accelerated dataplanes into OPNFV deployments. More specifically the talk will focus on FD.IO (VPP) and OVS DPDK integration into Apex, including different types of configuration options, platform requirements, performance tuning, and deployment challenges. This talk will also provide context to how OpenStack functions differently with these types of dataplanes, and how integration with the OpenDaylight controller works.

Energy consumption of Database Management - Florina Jonuzi
Presentation from Florina Jonuzi at the GSD Community Stage Meetup on June 06, 2024
Microservice Teams - How the cloud changes the way we work
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
