Untrusting the Network

Aijay Adams

There is a plethora of information available from the devices which make up Facebook's global datacenter and backbone networks, our devices report thousands of counters, some obvious in function, others less so. Despite our best efforts to collect and correlate, we still found that our network elements had a real knack for failing in creative ways which evaded traditional device counters and metrics.

In response to this situation Facebook has deployed monitoring across our network based on one core principle, don't trust the network. By monitoring on production paths through devices we are able to know how the network is really performing.

We have developed a number of tools which specialize in this large scale, end to end monitoring and fault isolation. The best part? much of the platform has been open-sourced so you can build on it for your own networks!

Optical Communications - where Physics beats Standards

Standards specifications, developed within respected international organisations such as the ITU, IEEE, ANSI, and IETF, are often thought to be crucial in enabling communications networks to be constructed, and for equipment from different vendors to interoperate. We like to claim that through use of common standards, global networks can be built to carry communications around, above, or below the planet.

In optical networking however, technology breakthroughs are being developed- and deployed in operational networks – far in advance of any established standards. Meanwhile, some of the published standards cause more confusion than cohesion, and make themselves obsolete with no practical application.

In this session I outline some of the latest developments in optical networking – and explore the scandalous world of networking without standards, and standards without any networks.


Paul leads the technology team at Trident developing a new subsea optical fibre cable from Perth to Singapore.

Sometimes described as a "Serial CTO", Paul has over 20 years direct experience in domestic and international carriers, wide-scale residential NGN access network deployment and broadband video delivery, with executive technical leadership roles in global carriers such as Global One/Sprint International, and Australian service providers including TransACT Communications, Basslink, Vocus Communications and other start-ups.

Rethinking Broadband Performance Comparison using Big Data from M-Lab

Xiaohong Deng

Broadband network performance is multi-faceted, dependent on factors such as access link characteristics, speed-tier, server distance, host buffers, ISP network dimensioning, and time-of-day. Daily or monthly aggregates, published by content providers such as Netflix and Youtube, present a highly simplified view that do not distinguish the impact of the above factors, making the comparisons potentially unfair and incorrect. Our paper revisits broadband performance using open data from M-Lab, utilizing nearly 5 million measurements taken over a 12-month period across 19 ISPs in 3 continents. We first develop a tool that allows a non-expert to query, process, and visualize M-Lab data by applying various filters and granularities via a simple web-based interface. Using this tool, we characterize the influence of the various factors, and find that there are significant biases affecting the averages, including disparities amongst households in their frequency of testing and access speed-tier, that contribute to fluctuations and biases in ISP performance comparisons. We then apply statistical and causal inference techniques to reduce the sampling bias, and find that the disparity amongst ISPs is lower than current averaging methods indicate, with hourly variations giving a truer indication of well-dimensioned ISP networks.


Xiaohong is a Ph.D candidate and causal academic stuff with UNSW, with research interests in Machine Learning and it's application to network measurement data, IoT data and security data.

Prior to UNSW, Xiaohong has been working in IT in different roles since 2007: Software Engineer, Project Lead, Technical Trainer, and CEO of an on-line education startup.

Multi-layer path computation

Beatty Lane-Davis

Traffic engineering is a complex topic. It was hard in native-IP networks and while MPLS provides all the hooks for TE, it's still challenging to get right in a distributed fashion. This has resulted in a high percentage of MPLS networks running RSVP-TE, but very few using RSVP-TE for actual bandwidth reservation.

This talk will look at the inherent challenges of TE, look at its evolution, and dig into the current standards work aimed at tackling these problems once and for all. Finally we will consider how taking a multi-layer approach to traffic engineering can provide optimal efficiencies in network resource utilization.

Optical Transport Technologies for Data Center Interconnection (DCI)

New breeds of optical technologies have changed the way how data centers are connected to each other. While dark fibers might still be popular and provide cost effective medium to connect data centers in a point-to-point fashion, in some Asian countries, such as Japan, Singapore and Hong Kong, dark fibers are in high demand among content providers, internet service providers and network service providers. Especially for some colocation providers, a well-designed DCI network has become an important part of their business that foster new business innovation and ideas.

The session is designed for audience who has little or no optical knowledge or exposure to the subject of optical networking. It covers some fundamental concepts, explaining the essential 'lego' blocks for designing an optical network as well as upcoming future trends in optical technologies for DC interconnection.

Update on CAIDA spoofer project

Matthew Luckie

Despite source IP address spoofing being a known vulnerability for at least 25 years, and despite many efforts to shed light on the problem, spoofing remains a viable attack method for redirection, amplification, and anonymity. Recently, CAIDA took over stewardship of the spoofer project, with the goal of increasing the density of crowd-sourced measurement of ingress filtering, and publicly providing evidence of where remediation attention should be focused. In this talk, I will discuss the new measurement system we developed, present the public reporting website, and discuss methods to infer lack of ingress filtering of customer ASes by provider ASes using publicly available data.

Auto remediation of networking systems failures: Operations Automation - What's the time? Its NETDEV time!

Companies such as Facebook and Netflix have driven down the cost of operating their networks by typically having very few Ops engineers on call. This is made possible by automating manual procedures and workflows. Network automation isn't as "black arts" as it once was, and doesn't require a whole team of crazy developers to accomplish. In this talk we will discuss and demonstrate how simple it now is to remediate some typical network failures without human intervention, from the simple BGP peering failure to more complex failure scenarios involving multiple variables or complete systems failure.

Mark Smith

The Trouble with NAT

Mark Smith

NAT has been widely deployed in IPv4 networks since its invention in 1994. My first experience with NAT was in 1995, where I failed to successfully deploy it for a customer due to one of its intrinsic limitations. Since then I've encountered or discovered other NAT limitations.

Avoiding these NAT imposed limitations have been one of my main motivations to work on and advocate the deployment of IPv6.

I've also since realised a set of network characteristics that I consider to be essential to the successful operation of a network.

In this presentation I'll first present and discuss these network characteristics. We'll then look at the various limitations that NAT imposes in the context of these essential network characteristics.


Mark started working in the industry in the early 1990s. He has held a variety of positions, starting in desktops and servers, and then changing to networking in 1998. He has experience at public and private enterprises, system and network integrators, telcos and ISPs. Most recently he has been working on smart meter networks in the utility sector.

Mark has been participating in the IETF since 2002, primarily the IPv6 related Working Groups.

Mark is also past presenter at AusNOG, having presented at 4 of the past 5 conferences.

In this presentation he will give a talk about comparison among IXPs in Asia Pacific, as well as those in other regions like Europe, Latin America, Africa, and North America. Also current peering scene and outstanding issues for IXPs in this region.

Comparison will be used some Key Performance Indicators such as number of ASN, peak traffic, and average traffic per ASN. They indicates how many ISPs you could peer, how much traffic could be distributed, and how big is each ISP in the IXP, respectively. Not only ranking in Asia Pacific IXPs but also he compares them with some famous IXPs in other regions, figuring out some features in each region.

The current peering scenes and outstanding issues will be presented by picking up some example countries like advanced countries and developing countries. In particular Japan is mature broadband market and 4 commercial IXPs are competing with each other, so he will give a talk on it. With regard to outstanding issues, he will also present operation experiences at JPNAP, the biggest internet exchange in Japan.
