3. IPv6: Passing on Lessons Learned from My Journey [pptx]
IPv6 and I met back in the early 2000s. At the time it seemed to me nothing more than IPv4 with 128 bits and some cool hex. That all changed the day that I read that IPv6 had no broadcast. That was the day I truly started really looking at IPv6. That was also the day that I started truly learning IPv6. Ever wonder things like: if there is no broadcast, how do MAC addresses get resolved? What is this weird link-local thing? Why are there so many 3s in the sniffer trace? What is solicited-node multicast? In this session I will share my journey of the questions I had and what I found the answers to be.

5. InterTubes: A Study of the US Long-Haul Fiber-Optic Infrastructure [pdf]
The complexity and enormous costs of installing new long-haul fiber-optic infrastructure has led to a significant count of infrastructure sharing in previously installed conduits. In this paper, we study the characteristics and implications of infrastructure sharing by analyzing the long-haul fiber-optic network in the US. We start by using fiber maps provided by tier-1 ISPs and major cable providers to construct a map of the long-haul US fiber-optic infrastructure. We also rely on previously underutilized data sources in the form of public records from federal, state, and municipal agencies to improve the fidelity of our map. We quantify the resulting map’s connectivity characteristics and confirm a clear correspondence between long-haul fiber-optic, roadway, and railway infrastructures. Next, we examine the prevalence of high-risk links by mapping end-to-end paths resulting from large-scale traceroute campaigns onto our fiber-optic infrastructure map. We show how both risk and latency (i.e., propagation delay) can be reduced by deploying new links along previously unused transportation corridors and rights-of-way. In particular, focusing on a subset of high-risk links is sufficient to improve the overall robustness of the network to failures. Finally, we discuss the implications of our findings on issues related to performance, net neutrality, and policy decision-making.

6. VXLAN Deployment in IX Fabrics [pdf]
Recently, very large Internet Exchange (IX) fabrics are undergoing transitions from VLAN-based architecture to VXLAN-based architecture, primarily because of inherent limitations in VLAN scalability, demand for loop free topology, ECMP or dynamic re-routing capability on failures. While it makes sense to change from VLAN to VXLAN, challenges are seen in rolling out this migration with minimal impact to existing customers in the network. In this session we will discuss some of the challenges we have encountered and how we solved the migration with minimal disruption to existing Customer deployment.

8. Source Routing Re-Imagined [pptx]
Operators have always been interested in source routing due to its determinism and ability to engineer traffic. However, traditional source routing using IP header options was never widely deployed due to security concerns. Recent buzz around SPRING (a.k.a. Segment Routing) has re-invigorated interest in source routing technologies, but for many operators moving to SPRING represents a significant change in their operating practices. Many of them are looking at more incremental approaches where they apply new source-routing concepts brought by SPRING, but implemented with current technologies with minor augmentations.In this talk we will review the new concepts SPRING brings to network design, and will then focus on using existing protocols for achieving similar benefits. We will discuss:

9. Segment Routing – Traffic Engineering [pptx]
In this talk, we would look at Segment Routing traffic engineering primarily focused around inter-area/multi-domain traffic engineering. We will look at how certain approaches with Segment Routing can help in solving the challenges associated with multi-domain traffic engineering in a simple and scalable manner. We will look into various components associated with multi-domain traffic engineering and approaches to solve multi-domain traffic engineering.
• On Demand Next-Hop
• BGP SRTE Dynamics
• PCE HA
Segment Routing (SR) works by encoding a path across a network as an ordered list of segments, which may be links, multi-hop tunnels between nodes, and more. SR uses today’s dataplane technologies without any modification, supports MPLS, IPv4 and IPv6, and requires only very modest changes to existing routing protocols. SR is also fully documented in IETF drafts with both multi-vendor and multi-operator contribution, thereby increasing the likelihood of interoperable implementations. Segment Routing allows operators to program new service topologies without the traditional concerns around network state explosion. Using SDN procedures, the head end can program a ordered list of segment identifiers (MPLS labels, IPv6 routing headers) that enable explicit source routing. This can allow for service level differentiation, potentially providing new enhanced service offering opportunities for operators. SR can be introduced slowly into a network without any flag day events, thereby minimizing disruption.
10. DDoS Threat Landscape [pdf]
Since the first denial of service (DoS) was launched in 1974, distributed denial of service (DDoS) and other DoS attacks have remained among the most persistent and damaging cyber-attacks. These attacks create complex and dynamic challenges for anyone responsible for cyber security. In this presentation, Ron will cover a brief overview of common attacks, major attack types and tools, as well as actionable tools and tips for attack detection and mitigation.

13. NetFlow, Flow-Like Data and Their Many Uses [pptx]
Most operators know that flow (NetFlow, IPFIX, and sFlow) data can be collected from routers and switches, and can be used for network cost and planning analysis, attack detection, and peering analysis. But bulk flow data just shows the traffic to-and-from. ‘Augmented’ flow from load balancers, servers, and sensors listening on taps and span ports lets you answer new questions. In this talk, we’ll briefly review flow, ‘classic’ flow analytics and its use cases. We’ll also cover less common sources of flow like OSS sensor software and configs, load balancers, IDS sensors, server-side monitoring software, and nginx logs. Finally, we’ll discuss real-world use cases supported by ‘augmented flow’.

14. The Real Metric in Evaluating CDN Performance [pptx]
When researching web performance, it’s easy to be convinced that response time or time-to-first-byte (TTFB) is the metric that you need to optimize for. Those same articles and so called ‘experts’ will also tell you it’s extremely important to enable browser side caching, so that your clients don’t have to make a 304 request back to the CDN. Measuring ‘response time’ or TTFB, is simply measuring the performance of 304 responses (headers without content). These are the very requests you just eliminated with client-side browser caching! So, if you’re not re-requesting content from the CDN, you want that first request (200 response) to complete as fast as possible. That’s Time-To-Last Byte (TTLB) – That’s throughput!Learning Outcomes:
-Learn why TTLB/throughput is more important than just TTFB.
-Understand how to measure TTLB.
-Optimizing TTLB using Anycast.
-Learn which network monitoring companies use RUM to evaluate CDN file TTLB/throughput performance
