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 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)
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 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 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%
