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 OptionbyGeoff HustonChief ScientistAPNIC
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%
