This presentations speaks to the new and growing single-lambda 100G pluggables (100G-DR1/FR1/LR1) that are quickly taking over the space previously dominated by quad-lane (100G-SR4/LR4/ER4/ZR4) modules.

This presentation explores the practical challenges and solutions in accurately measuring campus network performance and Local Area Network (LAN) throughput using both manual and automated approaches. It features real-world case studies where unexplained slowdowns across campus buildings were traced to overlooked internal bandwidth, configuration, and latency issues. Three key tools are compared: iPerf3, a powerful manual benchmarking utility for detailed performance diagnostics; LibreSpeed, an automated, web-based solution for continuous throughput monitoring; and Smokeping, a latency visualization tool that helps detect micro-delays and instability within the LAN. The session demonstrates how combining these methods into a hybrid monitoring approach enhances end-to-end visibility across wired, fiber, and Wi-Fi segments, supports proactive capacity planning, and ensures efficient, data-driven network management.

Two real-world examples of using RIPE Atlas to diagnose routing/forwarding issues. And hints at other uses.

This presentation explains how we built a network bandwidth monitoring solution for our enterprise users using open-source tools. The main goal was to clearly understand overall traffic usage and see how much of the bandwidth is used for local versus internet traffic. We used LibreNMS to monitor device and interface performance through SNMP, and Akvorado to collect and analyse sFlow/NetFlow traffic data from our routers.By visualising everything through a single Grafana dashboard, the solution removes the need to switch between multiple monitoring systems, making it easier to use while improving accuracy and data security.

This presentation shares a real-world case study of how I transformed University of Dhaka's security posture following a cyberattack in late 2024. I demonstrate how academic institutions can build enterprise-grade resilience using open-source technologies (CrowdSec WAF, Wazuh SIEM, OPNsense, Proxmox) without massive budgets.

Key topics include: incident response and recovery, implementing behavior-based WAF with community threat intelligence, SIEM integration for unified monitoring, network segmentation strategies, and cost-effective security architecture. The session covers both technical implementation details and organizational lessons learned, making it valuable for institutions facing similar budget constraints.

Attendees will learn practical approaches to security transformation, including specific tool configurations, integration patterns, and how to leverage open-source solutions for comprehensive protection. I emphasize that effective security requires strategic thinking and community collaboration rather than expensive commercial solutions.

This talk will recap fundamental optical concepts, make an attempt to help understand coherent pluggables and how it makes IPoDWDM possible.

Is Artificial Intelligence a cheat, a powerful tool, or something more?

This presentation delves into AI's evolving role, drawing parallels to past technological shifts like calculators and Excel. We’ll explore the undeniable benefits of AI, from boosting productivity to enabling groundbreaking innovation, while critically examining its risks, including data hallucinations and the proliferation of misinformation. From AI's foundational purpose to the cutting-edge applications of generative AI in complex industries like network interconnection, join me to understand how this transformative technology acts as a tool, teaches new possibilities, and at times, plays the trickster, demanding an open yet cautious mind.

The Internet Engineering Task Force (IETF) works on developing the voluntary standards that underpin the global Internet. These standards often influence operational practices, network architecture, and protocol evolution across the ecosystem. This session will highlight some key developments at the IETF, including new standards proposals, newly chartered working groups, and hot topics gaining traction within the IETF community. Special attention will be given to areas of direct relevance to network operators.

Whether you’re tracking standards adoption, involved in deployments and operations, or just curious about emerging protocol trends, this talk will offer a concise, operator-focused view of what’s brewing at the IETF.

Most ISPs in Bangladesh rely on public DNS resolvers like Google or Cloudflare. This means operators have almost no insight into where their users’ CDN traffic is really going — which cache nodes serve them, and whether those are on-net or global.

This session shares a practical, low-cost approach using PowerDNS Recursor, ClickHouse, and Grafana to build local DNS visibility. We used live resolver logs to classify CDN answers (Udoy, Vendor, Global) for Facebook (FNA) and Google (GGC).

Attendees will learn how to instrument DNS within their own networks, interpret query-to-CDN mapping, and use the data for routing, cache deployment, and QoE improvement.

Internet Exchange Points (IXPs) are crucial components of today’s Internet ecosystem, enabling efficient interconnection among Autonomous Systems (ASes) and handling a substantial share of global Internet traffic. Their operation relies on Route Servers (RSes), which simplify public peering by allowing ASes to maintain a single Border Gateway Protocol (BGP) session rather than multiple bilateral ones. However, BGP's reliance on implicit trust exposes it to vulnerabilities that can be exploited to hijack or disrupt traffic. To mitigate these risks, IXPs commonly employ filtering mechanisms based on Internet Routing Registries (IRRs) and the Resource Public Key Infrastructure (RPKI). Current practices exhibit a critical blind spot: IRR-based filtering heavily relies on AS-SET objects, failing to explicitly bind IP prefixes to their legitimate AS, allowing misconfigurations or hijacks to evade detection. In this work, we formally define and analyse this vulnerability, demonstrating how it can be exploited to perform prefix hijacking via IXPs. We quantify its prevalence across a large set of IXPs. We further propose practical countermeasures to strengthen RS filtering and validate our findings using real-world data from the RSes of two major IXPs: AMS-IX and NAMEX.

Indonesia’s Internet ecosystem has evolved from a single Internet Exchange Point in 1997 to more than fifty IXPs nationwide, connecting over one thousand ISPs and thousands of non-ISP networks. While this growth strengthens domestic connectivity, it also creates complex routing challenges. Many ISPs now connect to multiple IXPs in Jakarta, leading to routing table bloat, suboptimal paths, inconsistent community tagging, and uneven visibility across networks. This presentation highlights real operational issues faced by Indonesian network operators, including congestion, asymmetric routing, and manual policy management caused by the absence of shared standards and unified monitoring systems. The discussion emphasises that multi-IXP routing problems are not only technical but also organisational. Achieving a stable and efficient Internet ecosystem in Indonesia requires improved communication, coordination, and transparency among ISPs, IXPs, and the broader networking community.
