It is one thing to write automation for new networks and services, but what if you need to replace old automation, and integrate seamlessly into an already running network?
This talk goes through the experiences and principles designing and implementing network automation in Telia Company, based on a project that ran over two years in Norway.
About the speaker:
Allan Eising is the lead...
In 2019 the danish ISP's Sydenergi and Eniig merged into Norlys. Shortly after, Norlys announced it would open their FTTH network for wholesale
To support wholesale services in a scaleable and automated fashion, new equipment needed to be installed in 270 locations in just 10 months
This presentation will cover this journey, including rollout of a new OOB network, the introduction of Netbox...
XR optics technology purpose-built to break the inherent limitations of traditional point-to-point optical transmission solutions. XR optics paves the way for disruptive network economics as 5G, fiber deep, and hyperscale cloud connectivity impose new challenges on operators. With game-changing innovation in coherent optical subcarrier aggregation, XR optics introduces a new pluggable and...
We will take you through:
1. 400G ZR/ZR+ optical interfaces
2. Open ROADM initiatives
3. Management including open APIs
1. Embedded optics in L2 / L3 devices
2. Price / Performance versus other type of traditional solutions
3. Hazels with vendor lock-in
Documentation is a vital part of the network industry. It allows us to quickly and correctly adapt new technologies, and spread best common practices. Unfortunately documentation is riddled with IP space that's actually globally routed (220.127.116.11/24). An unsuspecting network operator can copy/paste configuration, and inadvertently hijack the IPs, or send trash to the actual prefix operator...
The 400G market is growing with many more organisations looking to deploy 400G in the core & even lineside.
One thing to consider with 400G optics is that some of them use a ~75ghz grid which can create problems when used with a standard 100Hz based DWDM systems.
This lightning talk is aimed at highly the issue and providing options on how to overcome this issue by using passive DWDM systems
The TCP Authentication Option [RFC 5925] replaces TCP MD5 [RFC 2385]. It offers key change without session reset and authentication algorithm agility.
BGP monitoring has been around for years for service providers and most larger organizations have some sort of monitoring in place. The list of excellent presentations arguing the benefit of increased routing security is very long - so is the list of hijacking examples.
But say we were in an ideal world where hijacks do not happen because RKPI is fully deployed? Do we care about BGP...
At Arista, open-source automation tools like ansible and infrastructure as code workflows have been bread-and-butter in the DC network for a while, now we are bringing these workflows and methodologies into the SP/Core space with our ansible collection "AVD".
AVD stands for Arista Validated Designs and is a 100% open-source project that is built and maintained by over 50 individual...
Time and frequency synchronisation in television production have been governed by the technical demands of the cathode ray tube in close to 90 years. The move to flat screens and IP networks as display and carrier of video streams has put an end to this.
In this talk, we'll look at how the requirements for synchronising a modern TV production facility affect network design, and how to...
It’s been a couple of years since the first worldwide SRv6 deployment. Today we enjoy a rich ecosystem -routing vendors, merchant silicon, as well as opensource- and more importantly deployments in some of the largest networks. In this session we would like to highlight the state of SRv6 today, go through the existing deployment use-cases (with content contributed by those operators) as well...
Global bandwidth consumption increased 3 times in 2021 as digitization at work, home and school accelerated during the global pandemic. The wave of 400GE IP routing satisfied this bandwidth demand, with many optical module variants emerging depending on use case, cost and technology. With 800GE around the corner, early adopters will gain many benefits. But with the diversity of optical...
This presentation provides an update about Kea, a modern, open source DHCP server from ISC. It starts with some background history about ISC DHCP, its problems and the reasons why migration to Kea is desired. The major advantages of Kea (REST API, optional database backends, extensibility with hooks, performance) are discussed. The latest features and additions implemented in Kea 2.0 and...
AWS is bringing a new concept called "Localzones" to Denmark and 26 more countries in the coming year, there is also a global rollout of 400G in the Edge-network.
Will this affect my peering with AWS?
Fredrik will bring clarity to these things in the coming presentation
Alt title: Managing vendors at scale.
A talk about how Google manage vendors/repair the network "at scale"
Netnod explains the difference between redundancy and diversity, why diversity is required for secure operation, and give
the design of the Netnod time and frequency service as example of how that is implemented in reality.
With live streaming audiences sizes exploding, increasing bitrates for 4K/8K/AR, and a greater dependence on the network since the start of the COVID pandemic, are we approaching an inflection point for network resources consumed by live streaming? This talk will examine TreeDN, a tree-based CDN architecture designed to solve the scaling challenges of live streaming to mass audiences. TreeDN...
