THE AUSNOG-02CONFERENCESYDNEY 2008

About AusNOG

Australian Network Operators Group Community for network operators who

work with ISPs, content providers or other areas of the on-line industries in Australia

Platform for exchange of ideas, experiences, technical information and network with expert from the industry

Inaugural meeting was organized by volunteers in response to overwhelming demand

The AusNOG-2 Meeting

Two day conference 21-22nd August 2008 Held at Sydney Convention and

Exhibition Center, Darling Harbor. Wi-Fi connectivity available with IPv6 Total speakers: 20

Topics to be discussed

IPv6: Failure is an option Emerging Access Technologies Building remote PoPs 4 Byte ASN: The transit provider

perspective Internet Traffic and Attack Trends

IPv6: Failure is an Optionby

Geoff HustonChief Scientist

APNIC

IPv6: Failure is an Option (contd)

We’re running short of IPv4 pools 5th Feb. 2008, entire IPv4 pool will be

exhausted To adopt IPv6, we’re too late!!

Devices upgrades now ISPs need to pay for the upgrade, because the

customers wont!! It will create panic We’re not sure how successful it will be

So what do we do then!!??

There are 2.5 billion entries in the routing tables but less than 10% are found in packets

Use existing IPv4 infrastructure Use NAT intensely

NAT increases address space by 16bits Use NAT at a carrier level

Each NAT address can serve (on average) almost 200 addresses

Relinquish unused address space Current growth of internet can be served by

using only 4 pools of /8s What if have pushed NAT too far??

Use application level gateways (Proxies)

Emerging Access Technologiesby

Tom SkyesNEC Australia

Access Technologies are changing

Get rid of ATM by EFM (Ethernet on First Mile)

No Single Technology to address a specific need Population density Terrain Geographic region

VDSL2 deployment cases Shorten Copper loop

@ 0.75Km – 400Mbps/8Mbps @ 1Km – 25Mbps/5Mbps

Emerging Access Technologies (contd.)

QoS parameters are changing Teleworking

Online Gaming 2xVoIP 2x HDTV 8-10Mbps using MPEG-4 2xSDTV (4Mbps using MPEG-2 / 2-3Mbps

using MPEG-4) Internet

Point to Point Ethernet Single Ethernet port for every single customer Power budget is critical 1 Port = 1 Customer

Emerging Access Technologies (contd.)

Passive Optical Network (PON) BPON: 622Mbps/155Mbps

1 Port = 32 Customers EPON: 1.25Gbps/1.25Gbps GPON: 2.48Gbps/1.25Gbps

1 Port = 64 Customers Femtocell

In home 3G home base station Uplink provided by conventional broadband Better in building coverage and less tariff

Building Foreign PoPsby

Mark PriorJuniper Networks

Building foreign PoPs Why??

Buy a cheap transit Increase customer base

How?? Where transits are cheap

US West Coast Japan etc.

Choosing a facility Where there are no. of transit service providers

Local loop is available Change providers easily

24x7 remote hands Requirements for the facility

Space for racks Friendly remote hands Power requirements

Redundant 110/220 AC/DC HVAC

Building foreign PoPs

Costs Equipment Cable from the landing station to PoP Protection and alarm systems Racks

Equipment choices High reliability is a must Dual power option Redundancy Readily available and spares

Security

Internet Traffic Trendsby

Danny McPhersonArbor Networks

Internet Traffic trends

First statistical analysis on internet traffic in history (from 67 ISPs) Key statistics

1,270 BGP routers 141,629 interfaces More than 1.8Tbps of inter-domain traffic Data was validated using SNMP counters

TCP is the dominant protocol and then UDP Popular ports in use

Most Popular: TCP Port 80 (web) 2nd Popular: TCP Port 4662 (edonkey)

Youtube contributes 10% of the internet traffic Tiger effect: Traffic increased by 65% of the peak value for 4 hrs

IPv6 Total IPv6 traffic: 0.0026% ASNs with IPv6 BGP announcements: 0.3% IPv6 enabled hosts: 0.4%
