Alcatel-Lucent Cloud: Shaping the Future NFV OSS David Amzallag TM Forum 2013Alcatel-Lucent Cloud
Communication service providers have started to re-think the network with the objective to remove the walls between network services and network infrastructure, reduce expenditures and to achieve network elasticity and scalability. This new vision aims to change the way telcos are building and managing their networks and spans Software Defined Networking (SDN) as well as Network Functions Virtualization (NFV). As many network services will be comprised of virtualized network functions together with non-virtualized network functions, the expectations for a new operational model are including, among others, a real-time, zero-touch and fully programmable OSS that will share responsibilities with legacy OSS, Cloud Management/ Orchestration System, SDN Controllers and a new OSS for Applications.

It's common business policy for organizations of a certain size to have two data centers as part of a disaster recovery or business continuity plan. However, most enterprise - applications are not designed for or intended to use systems in two different locations.
Enter the notion of a data center interconnect, which extends an Ethernet network between two physically separate data centers. While the idea is simple, Ethernet wasn't designed to run across a wide area network. Thus, a DCI implementation requires a variety of technological fixes to work around Ethernet's limitations.
This report outlines the issues that complicate DCIs, such as loops that can bring down networks and traffic trombones that eat up bandwidth. It also examines the variety of options companies have to connect two or more data centers, including dark fiber, MPLS services and MLAG, as well as vendor specific options such as Cisco OTV and HP EVI. The report looks at the pros and cons of each option.
This whitepaper features the transition from traditional networking to software-defined networking or SDN. Find outlines of next-generation architectures.

Extreme is rethinking the data plane, the control plane, and the management plane. Extreme is a better mouse trap which delivers new features, advanced function, and wire-speed performance. Our switches deliver deterministic performance independent of load or what features are enabled. All Extreme Switches are based on XOS, the industries first and only truly modular operating system. Having a modular OS provides higher availability of critical network resources. By isolating each critical process in its own protected memory space, a single failed process can not take down the entire switch. Application modules can be loaded and unloaded without the need for rebooting the switch. This is the level of functionality that users expect on other technology. Reaching the twenty million port milestone is a significant achievement demonstrating how our highly effective network solutions, with rich features, innovative software and integrated support for secure convergence. VoIP/Unified Communica Fons/Infrastructure/SIP Trunking (SBC) – Because of strong ROI, investment in this segment remains on a very strong growth trajectory.
Enterprises depend on modular switching solutions for all aspects of the enterprise network: in the enterprise core and data center, the distribution layer that lies between the core and wiring closet, and in the wiring closet itself. Modular solutions provide port diversity and density that fixed solutions simply cannot match. There are also high-capacity modular solutions that only the largest of enterprises and institutions use for high-density and high-speed deployments. Modular solutions are generally much more expensive than their fixed cousins, especially in situations where density or flexibility are not required. Fixed-configuration stackable switches are typically cost- optimized, but they offer no real port diversity on an individual switch. Port diversity means the availability of different port types, such as fiber versus copper ports. Stackable switches have gotten better at offering port diversity, but they still cannot match their modular cousins. Many of these products now offer high-end features such as 802.3af PoE, QoS, and multi-layer intelligence that were only found on modular switches in the past. This is due to the proliferation of third-party merchant silicon in the fixed configuration market. Generally, a stack of fixed configuration switches can be managed as a single virtual entity. Fixed configuration switches generally cannot be used to provision an entire large enterprise, but instead are mostly used out at the edge or departmental level as a low-cost alternative to modular products.
Assumptions:
Ethernet is Open
Active/Active in the Fabric
Therefore:

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).

We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
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.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
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.

Data Center Fabric
Definition/Goals
– How do you optimally interconnect 1000, 10 000, 100 000 or more end points (servers, storage)
– E/W traffic vs N/S traffic
– Servers to servers inside the DC
– Clients to servers entering/servers to clients leaving the DC
– Full bisectional bandwidth
– Every end point has equal BW (TX/RX) with every other peer in the fabric
– Minimizing the number of connections
– Cables/fiber/transceivers can represent 50% of the cost of a Data Center
– Minimizing the number of hops to reach out any other peer in the fabric
– Latency impact
– Providing Redundancy when any node or any link fails
– Failure will happen – it’s just a question of time
– Being Flexible
– Can’t rewire a complete Data Center when going from 10000 to 10001 or 100000 to 100001 end points

Standard Enterprise DC Deployment?
CLOS/Fat Tree
Note: Connectivity shown for some path only for clarity
– In a Fat Tree, there are as many edge ports as spine ports
NE = NS
– Now the most deployed solution up to ~5000 edge ports
– Advantages:
– Non-blocking architecture
– Constant Latency
– Fat Trees have a constant bisectional bandwidth
– Bisection bandwidth scales linearly with the number of nodes
– There are alternate paths for resiliency
– Formulas
FT (m,h): each node has m/2 children and m/2 parents
m = number of ports per switch
h = tree level
machines = m*(m/2)^(h-1)
switches = (2h-1)* (m/2)^(h-1)
example: m =24, if h=2 -> 2048 ports if h=3 -> 3456 ports

Why using Layer 2 in 2016?
– Legacy support
– It works … “If it ain’t broke, don’t fix it”
– Some customers just don’t have the bandwidth to make big changes
– Some applications can’t be easily rewritten so Layer 2 extension remains a must have
– And introducing overlays is a no go considering the complexity (data/control and management planes completely different)
– From a pure technical perspective, Layer 2 is not dead
– Standardization around distributed ling aggregation is done – 802.1AX-2014 giving all vendors an opportunity to still
use Layer 2, but without any STP like solution (or STP used an “insurance” policy)
– HPE Aruba on the FlexFabric side is working on this implementation
– Proprietary implementations have been working for many years
– HPE Aruba Intelligent Resilient Fabric (IRF) – more than 5 years with the big chassis and ToR
– If TRILL remains a niche (supported by FlexFabric products), PBB/SPB provides an elegant alternative
– Compatible with all Ethernet L2 protocols
– Has a native OAM (Operation & Maintenance) – something that overlays are struggling with
– Simpler in nature than new overlays like VXLAN
– Has been used in production very successfully by HP IT since 2011
11. 11#ATM16
Why using Layer 3 in 2016?
– Technically sounder than Layer 2
– No STP (always very complex to manage …)
– Broadcast/Security concerns
– Proven at scale / Reduces size of failure domains
– The choice made by the majority of big cloud providers
– Draft RFC on this subject (Facebook/Microsoft): “Use of BGP for routing in large-scale data centers” here
– Limited and controller number of applications – different from vast majority of Enterprise IT
– Simpler by nature if you know BGP
– Simpler control plane protocols
– eBGP (different AS for each ToR) /ECMP (Equal Cost Multi Path) / BFD (Bi Directional Forwarding Detection)
– Power of BGP, combined to ECMP for load distribution and BFD for protocol convergence acceleration (~200ms)
– Considered more “secure” even if more work will be required
– All protocols completely supported by FlexFabric portfolio and the foundation of the first release of
OpenSwitch
12. 12#ATM16
Why using Overlays in 2016?
– Scalability – goes beyond the 802.1Q VLAN limitations (12bits/4096 IDs)
– Typically 16M services/tenants
– Essentially driven by VM mobility – L2 extension
– VXLAN as de-facto solution by VMware (NSX as part of their SDDC initiative)
– Encapsulation over IP – ability to cross L3 boundaries
– The fabric becomes a big L3 domain with L2 processing (encapsulation / de-capsulation) at the edge (NIC
or Leaf/ToR)
– Separation between “underlay” (L3 Fabric per previous slide) from the “overlay” (Hypervisor/Leaf/Tunnel instantiation)
– All DC fabric vendors do have an overlay solution today – including HPE Aruba with FlexFabric
– But keep in mind that careful attention is required
– Different data plane (additional header) makes Jumbo Frames a must have and will continue to evolve …
– Standardization around control plane is still work in progress (even if BGP EVPNs are here)
– Management is still a big issue – how do you quickly identify the root cause of the problem
– Is it the underlay? Is it the overlay?

Data Center Interconnect and EVI
• HPE Ethernet Virtual Interconnect (EVI) can be deployed for active/active DC over any Network
• EVI provides additional benefits such as:
− Transport agnostic
− Up to 16 Active/Active DCs
− Active/Active VRRP default gateways for VMs
− STP outages remain local to each DC
− Improves WAN utilization by dropping unknown frames and providing ARP suppression
