The document discusses the importance of taking a top-down approach to network design that begins by analyzing business goals and constraints. It emphasizes understanding the applications used, user needs, and collecting information on the existing network before developing logical and physical network designs. The network design process involves multiple phases including analyzing requirements, developing logical and physical designs, testing and optimizing the network, and documenting the final design.

A Case of Fusion Middleware (IlOUG Tech Days, July 2013)Lucas Jellema
NOPERU is the organization responsible for handing out permits that Corporations, Governments and Citizens need for activities that involve emissions -such as CO2 - or resource usage - such as energy or water. NOPERU works with 100s users from five locations. A transition is taking place from decentralized data, Oracle Forms based application silos, paper based documents, data oriented, outdated character based user interfaces to a future steeped in Fusion Middleware, with modern pages (ADF), a serviced oriented architecture with decoupling and reuse (SOA Suite and OSB), a unified database (Oracle 11gR2) and digital documents (WebCenter Content). Then a business process approach (BPM Suite & BAM) that aligns with how business really works and provides operational insight to managers. This presentation tells the story of the transition, functional, architectural and technological aspects.

"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.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. 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.

Software Delivery At the Speed of AI: Inflectra Invests In AI-Powered Quality
Chapter01
1. Top-Down Network Design
Chapter One
Analyzing Business Goals and Constraints
Copyright 2010 Cisco Press & Priscilla Oppenheimer
2. Top-Down Network Design
• Network design should be a complete
process that matches business needs to
available technology to deliver a system that
will maximize an organization’s success.
– In the LAN area it is more than just buying a few
devices.
– In the WAN area it is more than just calling the
phone company.
3. Start at the Top
• Don’t just start connecting the dots.
• Analyze business and technical goals first.
• Explore divisional and group structures to
find out who the network serves and where
they reside.
• Determine what applications will run on the
network and how those applications behave
on a network.
• Focus on Layer 7 and above first.
4. Layers of the OSI Model
Layer 7 Application
Layer 6 Presentation
Layer 5 Session
Layer 4 Transport
Layer 3 Network
Layer 2 Data Link
Layer 1 Physical
5. Structured Design
• A focus is placed on understanding data flow, data types, and
processes that access or change the data.
• A focus is placed on understanding the location and needs of
user communities that access or change data and processes.
• Several techniques and models can be used to characterize the
existing system, new user requirements, and a structure for the
future system.
• A logical model is developed before the physical model.
– The logical model represents the basic building blocks, divided by
function, and the structure of the system.
– The physical model represents devices and specific technologies and
implementations.
6. Systems Development Life
Cycles
• SDLC: Does it mean Synchronous Data
Link Control or Systems Development Life
Cycle?
• The latter for the purposes of this class!
• Typical systems are developed and continue
to exist over a period of time, often called a
systems development life cycle (SDLC).
7. Top-Down Network Design Steps
Analyze
requirements
Monitor and Develop
optimize logical
network design
performance

– Characterize the existing network
– Characterize network traffic
9. Network Design Steps
• Phase 2 – Logical Network Design
– Design a network topology
– Design models for addressing and naming
– Select switching and routing protocols
– Develop network security strategies
– Develop network management strategies
10. Network Design Steps
• Phase 3 – Physical Network Design
– Select technologies and devices for campus
networks
– Select technologies and devices for enterprise
networks
11. Network Design Steps
• Phase 4 – Testing, Optimizing, and
Documenting the Network Design
– Test the network design
– Optimize the network design
– Document the network design
12. The PDIOO Network Life Cycle
Plan
Design
Retire
Optimize
Implement
Operate
13. Business Goals
• Increase revenue
• Reduce operating costs
• Improve communications
• Shorten product development cycle
• Expand into worldwide markets
• Build partnerships with other companies
• Offer better customer support or new
customer services
14. Recent Business Priorities
• Mobility
• Security
• Resiliency (fault tolerance)
• Business continuity after a disaster
• Network projects must be prioritized based
on fiscal goals
• Networks must offer the low delay required
for real-time applications such as VoIP
16. Collect Information Before the
First Meeting
• Before meeting with the client, whether
internal or external, collect some basic
business-related information
• Such as
– Products produced/Services supplied
– Financial viability
– Customers, suppliers, competitors
– Competitive advantage
17. Meet With the Customer
• Try to get
– A concise statement of the goals of the
project
• What problem are they trying to solve?
• How will new technology help them be
more successful in their business?
• What must happen for the project to
succeed?
18. Meet With the Customer
• What will happen if the project is a failure?
– Is this a critical business function?
– Is this project visible to upper management?
– Who’s on your side?
19. Meet With the Customer
• Discover any biases
– For example
• Will they only use certain company’s
products?
• Do they avoid certain technologies?
• Do the data people look down on the
voice people or vice versa?
– Talk to the technical and
management staff
20. Meet With the Customer
– Get a copy of the organization chart
• This will show the general structure of the organization
• It will suggest users to account for
• It will suggest geographical locations to account for
21. Meet With the Customer
– Get a copy of the security policy
• How does the policy affect the new design?
• How does the new design affect the policy?
• Is the policy so strict that you (the network
designer) won’t be able to do your job?
– Start cataloging network assets that security
should protect
• Hardware, software, applications, and data
• Less obvious, but still important, intellectual
property, trade secrets, and a company's reputation
22. The Scope of the Design Project
• Small in scope?
– Allow sales people to access network via a VPN
• Large in scope?
– An entire redesign of an enterprise network
• Use the OSI model to clarify the scope
– New financial reporting application versus new
routing protocol versus new data link (wireless, for
example)
• Does the scope fit the budget, capabilities of staff
and consultants, schedule?
23. Gather More Detailed Information
• Applications
– Now and after the project is completed
– Include both productivity applications and
system management applications
• User communities
• Data stores
• Protocols
• Current logical and physical architecture
• Current performance
25. Summary
• Systematic approach
• Focus first on business requirements and
constraints, and applications
• Gain an understanding of the customer’s
corporate structure
• Gain an understanding of the customer’s
business style
26. Review Questions
• What are the main phases of network design per the
top-down network design approach?
• What are the main phases of network design per the
PDIOO approach?
• Why is it important to understand your customer’s
business style?
• What are some typical business goals for
organizations today?
Editor's Notes
Layer 8 of the OSI model encompasses office politics, budgets, training, and other human factors.
Resiliency means how much stress a network can handle and how quickly the network can rebound from problems, including security breaches, natural and unnatural disasters, human error, and catastrophic software or hardware failures. Some experts, including Howard Berkowitz, have a mild dislike of the word “resiliency” as it sounds too much like a stretched rubber band or a trampoline. As Berkowitz says in his excellent book, WAN Survival Guide (Wiley 2001), “I avoid designing networks that stretch too far, bounce up and down, or oscillate between normal and backup states.” So he likes “fault tolerance,” but he points out that it does not mean “immune to any conceivable threat.” Berkowitz states that, “A sufficient quantity of explosives can overcome the tolerance of any network.” :-)
User communities, data stores, protocols, and the current architecture and performance will be discussed in the next few chapters. This chapter focuses on business needs and applications, which should be the first area of research in a top-down network design project. Network design is iterative, however, so many topics are addressed more than once as the designer gathers more detailed information and conducts more precise planning. So, gaining a general understanding of the size and location of user communities, for example, might be appropriate at this stage of the design project, but user communities should be investigated again when characterizing network traffic.
