Skillsets in a Software-defined, Disaggregated, Machine Learning Network (DKNOG9)

• Kireeti Kompella (Juniper Networks)

The Network Industry is changing quite fast; new proposals and dramatically new concepts are everywhere. How practical are these ideas? What is the likelihood that they will be deployed in networks? Perhaps most importantly, what is the impact on network operator jobs, job descriptions and roles if these ideas come to pass? "The DKNOG association was founded in 2009 with the goal of providing a social platform to further the exchange of knowledge within the Danish networking industry." But, going forward, what knowledge makes sense for operators? How should it be acquired? This talk will attempt to shed some light on the directions that networking might take in the future, and the type of knowledge/skillsets that would be needed.

Segment Routing with Clarence Filsfils (DKNOG9)

• Joachim Jerberg Jensen (Cisco)
• Clarence Filsfils (Cisco)

Cisco Fellow, Clarence Filsfils will update us on Segment Routing as a technology as well as describe use-cases and deployments. The Session will end with a 30 min. demo

SD-WAN anno 2019 (DKNOG9)

• Marie Skouenborg (GlobalConnect A/S)

There are somewhere between 35-50 so-called SD-WAN vendors out there, and since it is a buzzword and not a technology, it is a bit of a jungle to figure out what to expect from a product labelled "SD-WAN". This talk aims to clarify this, by looking at some of the marked leaders, killing some myths and getting to the core of what to expect from an SD-WAN solution.

SDN Controllers in the WAN (DKNOG9)

• Julian Lucek (Juniper Networks)

Some operators have recently been deploying SDN Controllers in the WAN for the first time. This presentation discusses the protocols needed to underpin a quasi-real-time SDN Controller for the WAN, and the major applications of such controllers. The flow of the presentation is as follows: How an SDN Controller gains visibility of the network, using the following ingredients (i) BGP-LS for topology discovery, including attributes of physical links such as bandwidth and metrics. This will include a discussion of how a controller gains visibility across multiple AS’s, in the case of multiple-AS networks, (ii) Streaming telemetry for link and LSP statistics and link latency data (iii) Status of traffic-engineered LSPs via PCEP How an SDN Controller instantiates or modifies RSVP or Segment-Routed traffic-engineered LSPs across the network. Closed Loop Automation, for example (i) Automated traffic management, by moving LSPs if congestion is detected (ii) automatically rerouting low-latency LSPs if the latency on a link is detected as having increased (iii) automatically rerouting LSPs if a fault is detected in a link or node

The design consideration of BNG (Broadband Network Gateway) for the metro area network (DKNOG9)

• Yisheng Wu (Huawei)

Understanding BNG Broadband Network Gateway (BNG) is the access point for subscribers, through which they connect to the broadband network. When a connection is established between BNG and Customer Premise Equipment (CPE),the subscriber can access the broadband services provided by the Network Service Provide (NSP) or Internet Service Provider (ISP). BNG establishes and manages subscriber sessions. When a session is active, BNG aggregates traffic from various subscriber sessions from an access network, and routes it to the network of the service provider. The BNG effectively manages subscriber access, and subscriber management functions such as: • Authentication, authorization and accounting of subscriber sessions • Address assignment • Security • Policy management • Quality of Service (QoS) This talk will go through some of the design considerations when deploying a BNG function to a network.

400G - don't get confused with this transceiver generation & IEEE 802.3bs (DKNOG9)

• Thomas Weible (FLEXOPTIX GmbH)

Transmission speed of 400G is becoming a reality, with new challenges for optical and electrical components in high speed systems emerging as well. PAM4 modulation is one key component for 400G transmission with transceivers following Ethernet IEEE 802.3bs, this talk will be a show and tell into PAM4. With this knowledge, the design decisions behind the new formfactors OSFP, QSFP-DD, SFP56-DD and µQSFP are easier to understand. This talk will help you to: Design / build new kind of applications or connections with your networking gear in the field 100G will no longer be the fast option for IXP interconnections soon DR, FR4 and LR4 at 400G will be available Avoid pitfalls when designing your racks Be aware how power consumption and new plugs will be part of the new world of 400G transceivers.

Student introductions This year we have invited a number of students of networking to the conference. They will briefly introduce themselves and their school

Can we bridge the gap between industry and academia? (DKNOG9)

• Silvia Saldana Cercos (Telia Denmark)

Is high education a benefit or a drawback when working in the telecom industry? Is the academia providing the students with the necessary tools to understand what happens in the real world? What to look for when hiring a new employee? Do we, in the industry, exploit the tools, and energy from young students who look at the industry with new fresh eyes? Are industry and research too far from each to actually find any synergies between these two worlds? This talk aims to tackle these questions from a person who has had a foot in both worlds. The idea is not providing statements of truth, but rather share few reflections that could inspire new students defining their next step forward, challenge current ways of working of our colleagues on the industry, help hiring managers to define the profiles that will fulfill the tasks in the best way possible, and maybe serve as an eye opener to find potential new win-win situations.

Welcome to day 2

Peering Security (DKNOG9)

• Susan Forney (Hurricane Electric)

Peering is a great way to improve network performance and save on transit charges, but peering interfaces also can expose your network and make it vulnerable to attack. This talk addresses best practices for securing your peering sessions and a few tips for getting the most benefit from peering. The talk addresses routing security, port security, and talks about free tools from Hurricane Electric at he.net that can help with the tasks.

DK: Digital Kingdom for data centers (DKNOG9)

• Kim Schultz (Invest in Denmark)

I'll explain where we are today in terms of attracting foreign data center operators to Denmark, why this is happening, what are the benefits and issues, and what additional benefits may Denmark experience from this development over the next few years.

Looking ahead: BGP Routing Security (DKNOG9)

• Job Snijders (NTT Communications)

Routing security is on the move, things are looking up! So, what changes to routing security are in the pipeline? What will happen in the next 18 months? In this presentation we cover updates from around the world and the role of RPKI - the future is bright!

That thing called Flowspec (DKNOG9)

• Peter Lundqvist (Engineer Arista Networks)

Flowspec is by all means not a new invention to handle DDoS and volumetric based threats. In one way or another been around as a feature since 2008-2009. But never got the attraction and little vanished as a tool and concept... untill now. Implementations today mostly design to direct suspicious flows by direct certian prefixes to central located scrubber site for filtering and actions. The design to achive this mostly ref to as "Onramp&Offramp" which involves MPLS controlplanes and segmentation of traffic. Flowspec offers a greater toolbox now with not just redirect, but also drop, shape or lower the service for suspected flows already on the edge. This session aims to explain the Flowspec from design and develop to a ready product with all its experience. A Flowspec rule is much more than just ACL installed by BGP !

Entering the 21st Century of Route-servers. (DKNOG9)

• Emil Palm (Netnod)

We will be talking about Netnod's journey from running Bird only Routeservers based on a Perl module for configuration into running a fully automated routeserver setup based on the following; * MANRS * IRR Filtering * RPKI Filtering * Alice LG (Lookingglass) * BGP Community filtering * With Examples And some upcoming Netnod news.

Enabling Automated DDoS Defence to Terabit Networks (DKNOG9)

• Peter Cutler (Corero)

Providers are often challenged by the cost and complexity of traditional DDoS protection systems, resulting in partial solutions which are a fraction of their transit/peering capacity and are slow and manual in their operation. High-performance traffic filtering and telemetry in the latest generation of edge routers is opening up new opportunities for security policy enforcement, including enabling real-time DDoS protection at a scale and low cost of ownership not previously possible.
