1. The document discusses network and computing bandwidth demands increasing exponentially over the next decade, requiring network designs to double bandwidth every 18 months for networks and 24 months for computing.
2. It addresses challenges in network design from these increasing demands, such as needing larger routers, more routers to avoid overloading domains, and seamless services across different network segments.
3. The role of segment routing and traffic engineering is discussed for optimizing network capacity and meeting policies around high bandwidth paths, low latency paths, and avoiding congested network resources.

A presentation to help new network operators plan a project to improve their network traffic management. Useful for inbound and outbound heavy networks. Lists the things you need to do to reach routing and peering nirvana.
Segment routing is a technology that is gaining popularity as a way to simplify MPLS networks. It has the benefits of interfacing with software-defined networks and allows for source-based routing. It does this without keeping state in the core of the network and needless to use LDP and RSVP-TE.

Description:
Networks are moving toward simplification, increased operational efficiency, and programmability using technologies such as software-defined networking. Cisco continues to demonstrate innovation by introducing the concept of segment routing in the data center, making the network more intelligent and adaptive to the applications running on top of it. Segment routing delivers application-optimized network transport. Encoding the path information directly at the source (that is, either at the virtual switch or at the top of rack) and using per-app policies, segment routing puts control in the hands of the network operators by empowering them to create secure, adaptive, and optimal paths based on the requirements of the application itself.
Please join us in the session to learn how Cisco is helping organizations increase network efficiency by allocating resources on demand and optimizing the network to better support business-critical applications, all while preserving security.
Agenda
Topics to discuss include:
- Introducing segment routing
- Why the need for application-optimized transport
- Features and benefits of segment routing
- Differences between segment routing and MPLS transport
- Relevance of segment routing in the data center
- Use cases and applicability of segment routing
- Summary and conclusion
For enterprise network engineers, implementing BGP can be an intimidating task. This presentation was given to address common architectures for internet and MPLS BGP usage, along with best practices.

Topic of Presentation: Programmable and Application aware IP/MPLS networking
Language: English
Abstract: The session will cover the topic of controlling and managing IP / MPLS architecture using SDN. The concept of Segment Routing (SR) will be presented as this is currently a subject of IETF standardization. The Segment Routing protocol extends the existing set of IP / MPLS-oriented mechanisms to control network using the SDN controller. The concept of support for Segment Routing based on Open Daylight architecture will be shown. Jeff will present examples of Segment Routing applications such as: optimization of the network in near real-time, network applications optimized angle and multi-tenant environment, segment routing and packet optical networks. Jeff Tantsura (speaker) is the co-author of emerging standardization documents relating to Segment Routing.

Cisco Live! :: Introduction to Segment Routing :: BRKRST-2124 | Las Vegas 2017Bruno Teixeira
This session provides an overview of the segment routing technology and its use cases. This new routing paradigm provides high operational simplicity and maximum network scalability and flexibility. You will get an understanding of the basic concepts behind the technology and its wide applicability ranging from simple transport for MPLS services, disjoint routing, traffic engineering and its benefits in the context of software defined networking. Previous knowledge of IP routing and MPLS is required.
Software Defined Network (SDN) using ASR9000 :: BRKSPG-2722 | San Diego 2015Bruno Teixeira
With the changing paradigm of network programmability using Software Defined Network (SDN), we are seeing new ways for monitoring, scaling and configuring network devices. With new network programability capabilities utilizing NETCONF, OpenFlow, BGP-LS, and PCEP it is vital for network architects and operations engineers to understand how these SDN related technologies can be leveraged to streamline the way we view, design, and operate our networks today. This session introduces these concepts and focuses on the use cases, implementation, and troubleshooting of these technologies on the ASR9000 platform.

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.
"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.
