Extreme is the only company in the industry that takes an architectural approach to bringing products to market (from R&D to product release). Everything we do and create is a part of this Software Defined Architecture [SDA]. Wireless LAN, Wired LAN, Data Center -- It starts with highly reliable, high performance infrastructure. This is our heritage and we have always been outstanding at this: WiFi, Campus LAN all the way to the Data Center. (Ranging from your user to the applications they consume.)
ExtremeXOS -- On top of this, we use a single consistent and differentiated OS call EXOS. (next gen HW will run on EXOS). Lots of companies make high performance hardware, so to truly offer value added differentiation; we include an integrated layer of software into our architecture.
Network Management & BYOD -- We fully integrate management across our entire portfolio. We are very proud that in only 5 months, NetSight became the management platform for the entire portfolio. This was an emphatic message to the market that we take a different approach aligned to our SDA. NetSight has a single, integrated database for all aspects of management. This streamlines operations, enables dynamic management and removes the manual aspect of correlating information.
Application Analytics -- Purview offers application layer analytics, so you can understand what is happening on your network, you can optimize your environment, help increase productivity and measure adoption. Purview allows you to deliver both tactical and strategic information to make better more rapid business decisions.
Finally, we offer orchestration across the entire architecture. Whether that infrastructure is multi-vendor or not. Orchestration within the data center is available across virtualized workloads and consolidated storage and compute. Extreme is the only company in the industry committed to this type of integration, backward compatibility and openness to support technology partners and third party vendors. Many in the industry have grown through M&A, successfully so, however it has led to a portfolio with lots of products that are not integrated through management or orchestration. Each time you add a product, it increases your complexity with the introduction of a new disparate management tool.
An experience is a personal and emotional event we remember. Every experience is established based upon pre-determined expectations we conceive and create in our minds. It’s personal, and therefore, remains a moving and evolving target in every scenario. When our experience concludes and the moment has passed, the outcome remains in our memory. Think about what makes you happy when connecting with your own device and then think about what makes you really upset when things are hard, complicated, and slow. If the user has a bad experience in anyone of these areas (simple, fast, and smart), they are likely to leave, share their negative experience, and potentially never return. Users might forget facts or details about their computing environment but they find it difficult to forgot the feeling behind a bad network experience. When something goes wrong with the network or an application, do you always get the blame?
So what can Ultra Low, consistent latency deliver? Low latency is a requirement for intensive, time critical applications. Latency is measure on a port-to-port basis, that once a frame is received on a ingress port how long does it take the frame to go through the internal switching infrastructure and leave an ingress port. The Summit X670 Top of Rack switch supports latency of around 800-900usec while the Black Diamond chassis, BDX8, can switch frames in a little as 3usec. We’re big believers in the value of disaggregation – of breaking down traditional data center technologies into their core components so we can build new systems that are more flexible, more scalable, and more efficient. This approach has guided Facebook from the beginning, as we’ve grown and expanded our infrastructure to connect more than 1.28 billion people around the world.
Flatter networks. Traditional data center networks have a minimum of three tiers: top of rack (ToR), aggregation and core. Often, there is more than one aggregation tier, meaning the data center could have three or more network tiers. When network traffic is primarily best effort, this is sufficient. But as more mission-critical, real-time traffic flows into the data center, it becomes critical that organizations move to two-tier networks.
An increase in east-west traffic flows. Legacy data center networks are designed for traffic to flow from the edge of the network into the core and then back to the edge in a north-south direction. Today, however, factors such as workforce mobility, Hadoop, big data and other applications are driving east-west traffic flows from server to server.
Virtualization of other IT assets. Historically, compute resources such as processor, memory and storage were resident in the server itself. Over time, more and more of these resources are being put into “pools” that can be accessed on demand. In this case, the data center network becomes a “fabric” that acts as the backplane for the virtualized data center.
In today’s Experience Economy, networks must provide a great user experience meeting each individual’s personal expectation. Users do not care about what happens behind the scenes to make everything work; in fact, users don’t even consider it until something breaks. People living in today’s Experience Economy care about simply connecting to a video, where the network is smart enough to remember who they are without a lot of hassle connecting, and then providing a blisteringly fast connection so that there is no interruption to the video stream. Think about what makes you happy when connecting with your own device and then think about what makes you really upset when things are hard, complicated, and slow. If the user has a bad experience in anyone of these areas (simple, fast, and smart), they are likely to leave, share their negative experience, and potentially never return.
Where Does Networking Fit In? To gain the full benefits of cloud computing and virtualization and achieve a business agile IT infrastructure, organizations need a reliable, high-performance data center networking infrastructure with built-in investment protection. Several technology inflection points are coming together that are fundamentally changing the way networks are architected, deployed and operated both in the public cloud as well as the private cloud. From performance, to scale, to virtualization support and automation to simplified orchestration, the requirements are rapidly changing and driving new approaches to building data center networks.
With Extreme Networks, IT can manage more with less. Automated intelligence and analytics for compliance, forensics, and traffic patterns translates into reduced help desk calls. Businesses can predict costs and return on investment, and increase employee productivity by securely onboarding BYOD, increasing both customer and employee satisfaction. A constant risk to the network, and ultimately the hospital, are unapproved applications and rogue devices that may appear on the network and either permit unauthorized access or interfere with other devices. A means to monitor all devices and applications that operate across the network is vital. Just as important are the audit and reporting capabilities necessary to report on who, what, where, when, and how patient data is accessed.
What is SDN? What software-defined networking really means has evolved dramatically and now includes automation and virtualization. Hardware is still a critical component in data center networking equipment, but the influence of switch software shouldn’t be overlooked. When everyone began to get excited about SDN a few years ago, we thought of it as only one thing: the separation of network control from network data packet handling. Traditional networks had already started down this path, with the addition of controller cards to manage line cards in scalable chassis-based switches, and with various data center fabric technologies.

Scalable Service-Oriented Middleware over IPDai Yang
ABSTRACT
Due to the increased amount of communication in cars, a reliable and easy to use middleware system for automotive applications becomes a popular research field. In this paper, we review a recent approach: the Scalable Service-Oriented Middleware over IP (SOME/IP). We present current tech- nologies and how SOME/IP differs from them. We point out how SOME/IP is ordered into the ISO/OSI layer model and discuss its service orientation. We also present the ad- vantages and disadvantages of SOME/IP. In the end, we analyze its timing behavior and whether it is suitable for automotive software or not.

DPI BOX: deep packet inspection for ISP traffic managementIlya Mikov
DPI BOX enables ISPs to cut their backbone costs by up to 25%. This is achieved by suppressing non-priority BitTorrent traffic during peak hours. Overall, this dramatically improves customer experience.
Beside that, with DPI BOX an ISP can blacklist arbitrary sets of IPs and/or URLs in order to comply with local Internet regulations.
DPI BOX is zero-administration, ready-to-use traffic management solution, works right from the box.
Insights on the configuration and performances of SOME/IP Service DiscoveryNicolas Navet
Scalable Service-Oriented Middleware on IP (SOME/IP) is a proposal aimed at providing service-oriented communication in vehicles. SOME/IP nodes are able to dynamically discover and subscribe to available services through the SOME/IP Service Discovery protocol (SOME/IP SD). In this context, a key performance criterion to achieve the required responsiveness is the subscription latency that is the time it takes for a client to subscribe to a service. In this paper we provide a recap of SOME/SD and list a number of assumptions based on what we can foresee about the use of SOME/IP in the automotive domain. Then, we identify the factors having an effect on the subscription latency, and, by sensitivity analysis, quantify their importance regarding the worst-case service subscription latency. The analysis and experiments in this study provide practical insights into how to best configure SOME/IP SD protocol.
This session will introduce the challenges and principles of designing high density WLANs.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan 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.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
