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
3
Two day conference 21-22 nd August 2008 Held at Sydney Convention and Exhibition Center, Darling Harbor. Wi-Fi connectivity available with IPv6 Total speakers: 20
4
IPv6: Failure is an option Emerging Access Technologies Building remote PoPs 4 Byte ASN: The transit provider perspective Internet Traffic and Attack Trends
6
We’re running short of IPv4 pools 5 th 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
7
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)

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
10
QoS parameters are changing Teleworking Online Gaming 2xVoIP 2x HDTV8-10Mbps 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
11
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
13
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
14
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
16
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) 2 nd 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%
