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.

Enabling Carrier-Grade Availability Within a Cloud Infrastructure

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.

Shuya Nakama, Okinawa Open Laboratory / NEC Solution Innovators, Eric Chang, Institute for Information Industry, Hideyasu Hayashi, Okinawa Open Laboratory and NEC Solution Innovators, Torii Takashi, NEC Corporation and Okinawa Open Laboratory 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.

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?

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.

Hear the overall vision for OPNFV, learn how the technical community functions, and get an understanding of the areas covered by 50+ active projects.

Opnfv vision, community and projects

OpenStack has been a part of OPNFV from the start and the OpenStack and OPNFV communities have strong areas of overlap. We will explain OPNFV from an Openstack and practical perspective, providing a specific example (SFC scenario) of how we are daily testing different components of OpenStack and other communities (ODL, OVS, etc). We’ll also talk about how OPNFV is useful to OpenStack because (hint: telco requirements & testing) and briefly describe several OPNFV projects which have contributed to OpenStack: NetReady, Multisite, Doctor, Cross CI, Copper, etc.

How OPNFV Uses OpenStack & How It's Useful

NFV solutions that pull from open source projects such as OPNFV, OpenStack, OpenDaylight, and others must be integrated and tested in an environment that fully supports the performance and availability requirements of service provider networks. We’ll show OPNFV performs open source NFV testing, including: methodology; mapping to ETSI NFV use-case/s; open source project integration; testing dashboards; Continuous Integration and Continuous Deployment (CI/CD); and testing acceleration. We’ll provide an overview of the OPNFV Pharos Community Test Lab infrastructure and the new Pharos Lab-as-a-Service to run a test deploy of OPNFV and try it out on your own. We’ll also give an overview of how OPNFV is working together with OpenStack Community as part of its Cross Community CI (XCI) effort in order to provide means for OPNFV developers to work with OpenStack master branch, reduce the time it takes to develop new features and test them on OPNFV Infrastructure, and more.

Gil Hellmann, Wind River, Xuesong Wang, Wind River, Qiao Fu, China Mobile, Jinglong Lv, China Mobile A traditional non-virtualization environment is fully integrated with the hardware platform, software platform, and service application as indivisible whole. It makes failure detection and HA much easier in north - south directions. In a virtualization environment, especially three-layer decoupling, the hardware platform, NFVI/VIM, VNF and even MANO may all come from separate vendors. This provides operators with more choices and flexibility. However, it also introduces challenges on how to achieve the same level HA as with non-virtualization environment. In this session, we will cover the following: • Common reliability strategy of traditional telecom network elements • The general HA mechanisms of VIM (OpenStack) platform today • What new requirements are brought to a VIM platform in the ETSI-MANO structure for a telecom-level high availability • The impact of various types of failures on the VMs and business programs, and some fault handling strategies performed by VIM and MANO according to our test results.

Hwee Ming Ng, Red Hat, Abhilash Vijayakumary, Red Hat Telco over Cloud is rapidly changing the telecommunications industry landscape by introducing cloud computing, virtualization paradigms and software approaches already in use and mature in traditional IT environments. While designing the cloud solutions for telco infrastructure understanding its information security risks and mitigation strategies are critical. Legacy approaches are inadequate, this session intends to help the operators to build and approach a telco cloud solution with the right cloud security knowledge. In this session we intend to explain the principle technologies of telco cloud based systems and strategies for safeguarding/classifying data, ensuring privacy and ensuring compliance with regulatory agencies for telco operators. We will also describe the role of encryption in protecting data and specific strategies for key management as well as how to select an appropriate solution to specific business requirements which are in well alignment with cloud based business continuity / disaster recovery strategies. We will also compare baseline and industry standard best practices by doing risk assessments of existing and proposed cloud-based environments. Additionally, presentation will focus on specific technologies like virtual firewalls, security zones, virtual tenant networks and their mapping to various use cases/challenges which an operator faces while designing the telco cloud.

Implementing a real NFV solution is difficult, so we have the OPNFV platform. Building and deploying OPNFV platform is difficult, so we have the powerful installers. Now verifying the deployment platform suitable for VNFs is also difficult: different hardware/components/installers/SDN controllers/VNFs, what do we have? This presentation will first introduce the methodology of pre-deployment validation of NFVI which defined in NFV ISG standard, then show how to utilize yardstick's generic test suites to examine basic infrastructure metrics that reflecting the specific VNF type requirements, and last explain how to analyze the benchmarking data by using yardstick dashboard. A demo will also be provided to show the whole validation process clearly.

Summit 16: The Hitchhiker/Hacker's Guide to NFV Benchmarking

The OPNFV project—a common integration and testing platform to facilitate NFV deployments that defines a consistent, functional stack—differs from more traditional code-based open source projects in that its work is focused upstream. Rather than re-event many wheels, the project leverages a variety of existing code bases from leading open source projects across compute, storage, and networking and fills gaps where needed to meet strict carrier-grade end user requirements. This approach is difficult and requires an extremely complicated set of requirements, but the result is a much needed common, de facto platform for the industry to test and build NFV products and services. OPNFV director Heather Kirksey spoke during LinuxCon North America 2016 on why the community chose to take this integrated approach, what’s been successful, and key lessons learned from this unique project.

Normalerweise mit der gleichen alten Ausrede: die (nicht)-funktionalen Tests seien zu aufwändig und zu teuer umzusetzen. Doch genau das Gegenteil ist der Fall! In diesem Vortrag gehen wir kurz auf die Bedeutung früher und regelmäßiger (nicht)-funktionale Tests von Cloud-nativen Anwendungen ein und erläutern, warum monolithische CI-Pipelines eine Sackgasse sind. Anschließend zeigen wir, wie einfach es ist, kontinuierliche Integrations-, Performance-, Security- und Akzeptanz-Tests mithilfe von Testkube zu integrieren und direkt im Cluster auszuführen.

Please download slides if blurred! == Continuous delivery is everywhere. Really?! Many teams still struggle to deliver well-tested product increments on a regular basis. Usually with the same old excuse: the (non)-functional tests are too complex and too expensive to implement thoroughly. But exactly the opposite is the case! In this talk, we briefly review the importance of early and regular testing of cloud-native applications and explain why monolithic CI pipelines are a dead end. We then show how easy it is to run integration, performance, security and acceptance tests continuously using Testkube directly on your Kubernetes cluster, fully integrated with a GitOps approach.

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

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.

Juha Kosonen, Nokia, Mika Rautakumpu, Nokia The Open Compute Project (OCP) is a collaborative community focused on redesigning hardware technology to efficiently support the growing demands on compute infrastructure. The designs have been optimized to lower cost of infrastructure and operations e.g. by removing non-essential components, disaggregating rack level solution with common resources, and simplifying server serviceability. OpenStack provides the foundation for the NFVI and MANO components within OPNFV. OPNFV releases Colorado and recent Danube have been successfully integrated to OCP hardware and running smoothly. Also hardware acceleration is supported. The concept itself has gained a lot of interest from mobile operators, some of them are running OPNFV on top of OCP hardware in their test laboratories too. This presentation will introduce how OpenStack, OCP and OPNFV open source projects fits perfectly together.

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.

Distributed vnf management architecture and 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.

Doug Smith, Red Hat, Inc, Gergely Csatari, Nokia There is an anecdote about a tourist lost in the middle of the countryside in Ireland, who pulls over and asks a local, "How can I get to Galway from here?" To which the local, after thinking for some time, responds, "If I was going to Galway, I wouldn't start from here at all." Cloud native application development can feel like that sometimes, especially in the telecom industry. I have an application, it's running fine on a bare metal server, and now I am expected to make it resilient, scale-out, cloud native, microservice architecture, buzzword compliant. But how do you get there from where you are? This presentation will present the hero's quest, identifying the key constraint to cloud resiliency at each stage, and identifying measures for addressing them. By showing the evolution story from the perspective of two applications, including a real telecom application, this presentation addresses the practical problems. The approach is not "rewrite your app from scratch", it is refactoring for incremental improvements. Doug and Gergely will address the automation of application deployment and configuration, separation of state from behaviour, clustering, handling storage for cloud native applications, monitoring and event management, and container orchestration, so that, at each step along the journey, you know what problem you are solving, and how to get to the next step from where you are. This presentation is in addition to a series of workshops held at the summit sponsored by the Cloud Native Computing Foundation and organized by Dave Neary, and includes a short summary of the topics presented in those workshops in addition to the perspectives on how to complete the quest to cloud native applications.

Juha Oravainen, Nokia, Tapio Tallgren, Nokia In the future factory robots will communicate wirelessly and cars on the highways will exchange the information with each other. This requires extremely low latency mobile networks, known as 5G. This network will run on telco grade cloud platforms of which OPNFV is one example. The first cloud radio access networks have already been deployed to operators. More is needed with future technologies/networks as more functionalities will be moved to the cloud. This talk tells what is needed to overcome low latency and high availability challenges with cloud platforms. At Nokia we are continuously evaluating the latest OPNFV SW on Nokia HW with radio VNFs to guarantee interoperability with open source components.

Timo Perala, Nokia, Michael Wiegers, Ericsson To further enhance Network Functions Virtualization (NFV) industrialization, Cisco, Ericsson, Huawei and Nokia announced Memorandum of Understanding (MoU) to create the NFV Interoperability Testing Initiative (NFV-ITI) last year December. The main objective of NFV-ITI is to promote competition and create industry alignment on generic principles for NFV interoperability testing and support for specific customer situations. NFV-ITI will focus on testing interoperability configurations of commercial NFV solutions actually used in the communication services providers' networks. The initiative is open for ratification by any NFV vendor subscribing to the objectives of the MoU. NFV-ITI will address NFV multi-vendor interoperability challenges for communication service providers, enabling them to optimize NFV deployment and integration costs, and reduce time-to-market for new services. NFV-ITI will complement and heavily build on other industry interoperability activities, including but not limited to those of OPNFV, ETSI NFV Testing WG, and NVIOT Forum.

We perform this come-to-me love spell that works instantly with the aim of bringing back the victim to the person performing the magic. Have you lost your lover? Do u need to solve any relationship problem? Contact the powerful spells caster chief kule with love spells that work overnight and love spells that really work. Have you found yourself infatuated with a special someone you think could be the one? Are you looking for a spell to provide them with a nudge in the right direction? Or maybe the spell you cast didn’t achieve the results you were hoping for? Whether you’re new or versed in the ways of spell casting, we’re here to help. Today we’re going to provide you with a detailed guide on the types of love spells to cast. Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional. Practice your craft and expand your knowledge; understand that you will possess the ability to help others in time truly.
