WAN
To Internet

Traditional carriers' transport networks consist of vertically-integrated devices with vendor-proprietary interfaces, that causes "vendor lock in" environment and interferes with adopting software based control and configuration for carriers' transport networks. NTT Communications are trying to adopt disaggregation approach for them to transform our operations by integrating commoditized multi-vendor components and SDN technology. In this presentation, we will talk about our expectations for disaggregated transport networks and its controller architecture with multiple SDN controllers including open source software. Furthermore, we will show our internal evaluation result of disaggregated transport network feasibility and discuss future development plans.

NFV Testing

Open Networking Summit

A key tenant of moving NFV from a Proof of Concept (Poc) to deployment is testing. 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. Testing criteria and solutions are also required to ensure NFV interoperability between hardware and software systems that comprise NFV. In this tutorial, you’ll learn best practices for 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.

Network Virtualization Meets the WAN

Bruce Davie

Ildikó Váncsa, Chris Price, and Carsten Rossenhövel's presentation at the 2017 Open Networking Summit. Communications service providers (CSPs) have a wide range of options when building virtualized services from the ground up including multiple choices for each functional block in the ETSI NFV reference architecture. CSPs prefer heterogeneous systems with building blocks from different vendors including open source software; for such deployments interoperability becomes a crucial requirement. OpenStack, as the NFVI and VIM, serves as a widely used cloud platform for telecom and NFV use cases. As a common base, OpenStack offers the means for vendors and other open source projects to ease the interoperability challenge by providing a set of open API’s while focusing on upgradeability and backward compatibility. However, when it comes to productization, interoperability testing often falls short and is sometimes left to the carrier as shown by the testing programs actively run by no fewer than 10 organizations today. Join Carsten Rossenhövel from the European Advanced Networking Test Center (EANTC) and the rapporteur (editor) of ETSI’s NFV interoperability standards, Ildikó Váncsa from the OpenStack Foundation, and Chris Price, Ericsson and OpenStack board director to learn more about The ETSI NFV Release 2 interoperability testing activities - standardization and recently completed ETSI PlugTest. Over 40 commercial and open source implementations were tested for interoperability, including 20 virtual network functions, 10 management and orchestration solutions and 10 NFV platforms. The New IP Agency (NIA) interoperability testing campaigns of commercial NFV implementations executed by EANTC, focusing on results, lessons learned and recommendations. How vendors and open source projects are stepping up to the challenge, realizing they must work together. How to stay up-to-date with OpenStack releases and the community. How to get involved to ensure you are aware of the latest developments and contribute what you need to OpenStack. What will I learn from attending this session? CSPs, open source projects and vendors alike will learn more about the recent ETSI PlugTest and NIA-commissioned interoperability testing, their results and how to architect full NFV solutions that will work together. Interoperability API tests and associated marks from OpenStack will be covered, as well as features to help stay current on OpenStack releases. Attendees will also hear from Ericsson about a vendor’s point of view, and how other projects such a OPNFV are evolving and expanding in scope to address this challenge.

Container Service Chaining

Open Networking Summit

Martin Šuňal's presentation from Open Networking Summit 2017. Network Function Virtualization (NFV) and Service Function Chaining (SFC) have been hot topics for some time, but many users are still finding it difficult to adopt these concepts in the real world. Since network functions are getting virtualized/containerized and service chaining is a requirement in many NFV use cases, there is a need for container service chaining. This presentation discusses problems with existing approaches, potential solutions and benefits of container service chaining.

State of the OpenDaylight Union

Open Networking Summit

Lisa Caywood and Colin Dixon's presentation at the 2017 Open Networking Summit. OpenDaylight has become a nexus for open source integration, creating a new open networking stack and enabling a new generation of open source, agile IT infrastructure. The fifth “Boron” release provides new tooling and documentation to support application developers, as well as greater integration with industry frameworks from OPNFV and OpenStack to CORD and Atrium. Boron also brings a practical focus on two leading types of deployments: (1) direct control of virtual switches to provide network virtualization and NFV and (2) management and orchestration of existing networks to provide new features and automation. This talk will cover trends in open SDN and cloud networking, with a focus on Boron milestones. In particular, it dives into the architecture across OpenStack and OpenDaylight to enable OpenStack service function chaining support in OpenDaylight.

Midokura OpenStack Day Korea Talk: MidoNet Open Source Network Virtualization...

Dan Mihai Dumitriu

OpenStack deployments for public or private clouds require overlay networking. Due to the scale and rate of change of virtual resources, it isn't practical to rely on traditional network constructs and isolation mechanims. Today's deployments require performance, resilience, and high availability to be considered truly production-ready. In this session, we deep dive into the MidoNet architecture, and process of sending a data packet across an OpenStack environment through a network overlay. A distributed architecture implements logical constructs that are used to build networks without a single point of failure, all while adding network functionality in a highly-scalable manner. Network functions are applied in a single virtual hop. By applying network services right at the ingress host, the network is free from unnecessary clogging and bottlenecks by avoiding additional hops. Packets reach their destination more efficiently with the single virtual hop. After this session, the audience will understand how distributed architectures allow efficient networking with routing decisions and network services applied at the edge. Also, the audience will understand how it is easier to scale clouds when the network intelligence is distributed.

Packet processing in the fast path involves looking up bit patterns and deciding on an actions at line rate. The complexity of these functions at Line Rate, have been traditionally handled by ASICs and NPUs. However with the availability of faster and cheaper CPUs and hardware/software accelerations, it is possible to move these functions onto commodity hardware. This tutorial will talk about the various building blocks available to speed up packet processing both hardware based e.g. SR-IOV, RDT, QAT, VMDq, VTD and software based e.g. DPDK, Fd.io/VPP, OVS etc and give hands on lab experience on DPDK and fd.io fast path look up with following sessions. 1: Introduction to Building blocks: Sujata Tibrewala

[Webinar Slides] Programming the Network Dataplane in P4

Open Networking Summits

This webinar explains why PISA chips are inevitable, provides overview of machine architecture of such switches, presents a brief primer on the P4 language with sample programs for a variety of networks and demonstrates a powerful network diagnostics application implemented in P4. Programmability in SDNs is confined to the network control plane. The forwarding plane is still largely dictated by fixed-function switching chips. Our goal is to change that, and to allow programmers to define how packets are to be processed all the way down to the wire. This is made possible by a new generation of high-performance forwarding chips. At the high-end, PISA (Protocol-Independent Switch Architecture) chips promise multi-Tb/s of packet processing. At the mid- and low-end of the performance spectrum, CPUs, GPUs, FPGAs, and NPUs already offer great flexibility with performance of a few tens to hundreds of Gb/s. In addition to programmable forwarding chips, we also need a high-level language to dictate the forwarding behavior in a target independent fashion. "P4" (www.p4.org) is such a language. In P4, the programer declares how packets are to be processed, and a compiler generates a configuration for a PISA chip, or a programmable target in general. For example, the programmer might program the switch to be a top-of-rack switch, a firewall, or a load-balancer; and might add features to run automatic diagnostics and novel congestion control algorithms.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

"Impact of front-end architecture on development cost", Viktor Turskyi

Fwdays

I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
