Reducing services latency is pushing centralized computing power back to the edge of the network, and in this paradigm telecommunication companies are well position to fill the gap. Telefónica is utilizing open-source OpenNebula and ON.Lab's ONOS and CORD to prototype a new generation of Central Offices that are fully IPv6 compliant and allows for the deployment of programmable services rather than the traditional black box solutions provided by proprietary solutions.
Join Storage Switzerland and Pluribus Networks where we will answer the following questions:
• What are the benefits of open networking and SDN in the data center?
• How can I safely migrate to a disaggregated white box architecture when I have incumbent vendors deployed throughout my network?
• How do I deploy SDN in my data center and do I need a full hardware refresh to do it?

This document summarizes a presentation on supporting IPv6 with software defined networking (SDN) and network functions virtualization (NFV). It defines SDN as separating the control plane and data plane in networks to allow for programmable, automated configuration changes. OpenFlow is described as an SDN protocol. NFV aims to virtualize network functions to run on virtual machines. Current carrier-grade NAT (CGNAT) solutions are hardware-based, while SDN/NFV could allow for a virtualized CGNAT with benefits like dynamic load adjustment and disaster recovery. The future of networking is predicted to involve open source SDN controllers and virtual switches running on commercial and open source platforms.
This document discusses 5 trends enabled by 5G technology: distributed cloud, Internet of Things (IoT), artificial intelligence (AI), virtual reality (VR), and augmented reality (AR). It describes how each trend will require high-speed, low-latency networks with network automation. A distributed cloud architecture is needed to place computing resources at the edge of the network to meet latency and mobility requirements of these new applications. Open source networking and standardization will be important to realize this vision.
Colt has gained experience implementing SDN and NFV technologies including:
1) A SDN overlay for network virtualization in their data centers.
2) A modular managed service platform with SDN automation of the WAN.
3) A pre-NFV virtualized L3 CPE solution. Upcoming projects include an NFV proof of concept evaluating virtualized L3 CPE, load balancers, and route reflectors. The document also outlines potential use cases for SDN and NFV in mobile backhaul networks.

The document discusses telco cloud and network virtualization technologies including NFV and SDN. It provides an overview of how NFV and SDN enable programmability and virtualization of network resources to provide flexibility. NFV allows network functions to run in software on commercial off-the-shelf hardware, while SDN separates the network control and forwarding planes to enable centralized programmable network control. Together NFV and SDN can optimize resource utilization and simplify network management.
Comparing Open Source SDN Controllers, like OpenDaylight, OpenContrail, and ONOS is a challenge. Here, we’ll compare open source SDN Controllers. In a software-defined network (SDN), the SDN Controllers is the “brains” of the network.

SECURITY FOR SOFTWARE-DEFINED (CLOUD, SDN AND NFV) INFRASTRUCTURES – ISSUES A...csandit
This document discusses the security challenges of software-defined infrastructures including cloud, SDN, and NFV technologies. It outlines several issues such as insecure interfaces/APIs, malicious insiders, account hijacking, virtualization vulnerabilities, and service interruptions for cloud computing. For NFV, the key challenges discussed are hypervisor security issues that could allow attackers to access VMs and compromise the entire infrastructure. The document argues that these technologies introduce both traditional security risks as well as new technology-specific risks, and that a software-defined security approach is needed to address challenges across integrated cloud, SDN, and NFV platforms.
SDN and NFV both aim to virtualize and commoditize network hardware to reduce costs and increase flexibility. SDN separates the control plane from the data plane to allow centralized control of network behavior via software. NFV virtualizes network functions like firewalls and load balancers that were traditionally hardware appliances. Both seek to standardize networking functions through open source projects and standards bodies like ONF for SDN and ETSI for NFV. Major implementations include OpenStack for virtual infrastructure, OpenDaylight as an SDN controller, and OpenFlow as the SDN protocol. While complementary, SDN and NFV face challenges around vendor support and complexity that could slow wide adoption.
SDN and NFV both aim to virtualize and commoditize network hardware to reduce costs and increase flexibility. SDN separates the control plane from the data plane to allow centralized programming of network behavior, while NFV virtualizes network functions that were traditionally hardware-based appliances. The two technologies complement each other and are being developed through open standards and open source projects to drive industry adoption. Major challenges include developing common frameworks and ensuring interoperability between solutions.

Research Challenges and Opportunities in the Era of the Internet of Everythin...Stenio Fernandes
Currently there is increasing interest in scientific research on network traffic management for advanced scenarios (e.g. Internet of Everything (IoE), Everything as a Service (XaaS), Smart Cities, and the like) and their respective demands for novel network services. Such networked applications bring massive amounts of traffic data to be processed in real-time, thus driving researchers to develop affordable yet efficient network management systems. In fact, new paradigms, services, and architectures, such as Network Virtualization (NV), Software-Defined Networking (SDN), Distributed Cloud Computing, Network Functions Virtualization (NFV), Service Function Chaining (SFC), etc, will require robust and dynamic capabilities to support a myriad of possibilities for applications from the IoE and XaaS concepts. For example, there is a need for an in-depth understanding of the composition and the dynamics of Internet traffic to perform accurate capacity planning, deploy efficient management policies and pricing strategies, assess protocol performance, and detect abnormalities in such scenarios. Research on measurement, modeling, and analysis of network traffic and infrastructure always face new challenges as new applications are continuously deployed.
In this talk, I will discuss the rise of IoE and XaaS as well as the demand for advanced networking services, paradigms, and architectures (e.g., SDN, NFV). I will give an overview of some challenges, opportunities, and directions in these research topics.
This paper focuses on the evolutionary stages for cloudification then covers the key software building blocks that will be needed to enable NFV, and ultimately ICT transformation to 5G. It describes how Intel® Open Networking Platform (Intel® ONP) Server running on innovative new networking platforms based on Intel® silicon can help reduce the cost and effort required for service providers and vendors alike to adopt and deploy SDN and NFV architectures.
This document provides an overview of performance evaluation for software defined networking (SDN) based on adaptive resource management. It begins with definitions of SDN and discusses its architecture, advantages, protocols, simulators, and controllers. It then outlines challenges in SDN including controller scalability, network updates, and traffic management. Simulation tools like Mininet and Floodlight and Open vSwitch controllers are explored. Different path finding algorithms and approaches to resource management optimization are also summarized. The document appears to be a student paper or project on evaluating SDN performance through adaptive resource allocation techniques.
The document discusses Edge computing and the Akraino Edge Stack project. It provides an overview of the Linux Foundation Edge (LF Edge) organization and its goals of establishing an open source framework for edge computing. It then summarizes the Akraino Edge Stack project, which aims to address telco, enterprise, and industrial IoT use cases through the creation of tested and validated deployment-ready blueprints for edge cloud configurations. It outlines several blueprints that were released in Akraino R1 and previews new blueprints and enhancements planned for the future.
The document discusses Software-Defined Networking (SDN), defining it as an emerging architecture that is dynamic, manageable, cost-effective and adaptable. It describes SDN protocols like OpenFlow that give access to network switches. It outlines the key aspects of the SDN architecture including being directly programmable, centrally managed, programmatically configured, and open standards-based. It also lists several related open-source SDN projects and protocols involved in SDN like Open vSwitch, ONAP, DPDK, OpenDaylight, ONOS, and PNDA.

Future Internet: Managing Innovation and TestbedShinji Shimojo
Innovation is a big key word for ICT research and development. However, a road toward innovation is facing full of uncertainties and there are many obstacles. key elements to overcome these obstacles seems to be agile management of people, software and hardware. In addition, we think involvement of users in R&D will have much effect on the management of uncertainty in R&D. In this talk, I talk on our approach to this user involvement in JGN-X, an international future internet testbed and Knowledge Capital, Osaka, an smart city experimental testbed.
This document discusses the deployment of a software-defined network testbed on the cloud. It begins with an introduction to software-defined networking and its advantages over traditional networking. It then discusses the design and implementation of an SDN testbed using OpenDaylight as the SDN controller, Mininet as the network emulator, and Wireshark for network traffic analysis. Various network topologies are implemented in Mininet including linear, single, tree and torus topologies. OpenFlow messages are captured to understand communication between the controller and switches. Network performance is evaluated by generating and measuring traffic across the testbed. The goal is to demonstrate and analyze the SDN concept in a practical virtualized environment.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
Getting the Most Out of ScyllaDB Monitoring: ShareChat's TipsScyllaDB

This talk shares our team's practical tips on: 1) How to find the root of the problem by metrics if ScyllaDB is slow 2) How to interpret the load and plan capacity for the future 3) Compaction strategies and how to choose the right one 4) Important metrics which aren’t available in the default monitoring setup.
"Frontline Battles with DDoS: Best practices and Lessons Learned", Igor IvaniukFwdays
At this talk we will discuss DDoS protection tools and best practices, discuss network architectures and what AWS has to offer. Also, we will look into one of the largest DDoS attacks on Ukrainian infrastructure that happened in February 2022. We'll see, what techniques helped to keep the web resources available for Ukrainians and how AWS improved DDoS protection for all customers based on Ukraine experience
From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
"$10 thousand per minute of downtime: architecture, queues, streaming and fin...Fwdays
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

3. Introduction
The “OpenDaylight Project” is a collaborative open source project hosted by The
Linux Foundation. The goal of the project is to promote software-defined networking
and network functions virtualization. The software is written in the Java programming
language.
OpenDaylight is a highly available, modular, extensible, scalable and multi-protocol
controller infrastructure built for SDN deployments on modern heterogeneous multi-
vendor networks.
Northbound API’s to apps (e.g. OpenStack)
Southbound interfaces to network devices (e.g. OVS)
4. Challenges in real world
Communications providers and enterprises alike are eager to build or adapt their
networks to be more flexible and responsive to their organizations’ and customers’
needs. At the same time, they are driving network automation to improve operational
efficiency.
That’s how, a movement grew out of a simple question :
Why shouldn’t networking devices be programmable just as other computing
platforms are?
5. Software-defined Networking (SDN)
The answer of that question is SDN. The benefits of SDN:
No more arcane protocols to learn.
No more waiting and hoping for networking vendors to develop specialized features
you need.
If you could develop your own features, you could then optimize your device
selection for price and performance independently of feature-richness.
Interoperability of different physical and virtual device types from different vendors.
Continuous visibility of flows from source to destination.
Common management framework for all devices.
Programmability to shape network behaviour according to users’ needs.
Automation of and by policy.
10. Usecase
SD – Core
• Traffic sharing between the switched and routed domains
Zero touch installation
• Automated setup of the software profile and services configuration
Brownfield adaption
• Integrates legacy systems and new SDN equipment in one-network with plug-ins
11. Usecase
Network Configuration and management
• Manage network devices with a single, consistent interface
Network analysis and policy control
• Automates analysis and action for pre-defined policies
Alarming and notification
• Maps underlying devices/EMS data to normalized model
12. Pros
Supports a wide variety of SBI protocols versions
Active community
Aligned with vendors and telco's
Easy proposal of projects
Easy development
13. Cons
Complex to install and operate
Not so good documentation (e.g. flavours)
Development of modules requires a deep knowledge of ODL
It’s not “Pure” SDN
