[H-GEN] Internet performance (fwd)

[Raymond Smith]

Some more information on the new AARNet. People interested in this sort of
thing might also want to keep an eye on uq.netstatus (if you can get the
group).

> OPTUS NETWORK IMPROVEMENTS FOR AARNET
>      
> BACKGROUND
>      
> The AARNet Optus Network was built during the months of April to August 97.
>      
> The National network  comprises ATM connections (and Frame Relay to Hobart an
> d 
> Darwin).
>      
> International configuration comprises bandwidth to the USA  via UUNet (16M)  
> and
>  CWIX (20M), with presently an additional 4M to UUNet terminated in Sydney.
>      
> Fine tuning of the international network is currently occurring as Optus beco
> mes
> familiar with traffic flows and trends.
>      
> The following network improvements are scheduled to occur, to further improve
>  
> the capacity and performance of the network, and connectivity to Tier 1 USA 
> ISPs.
>      
> NETWORK IMPROVEMENTS
>      
> SHORT TERM (currently)
>      
> Fine tuning of load sharing between UUNet and CWIX routes.
>      
> Fine tuning of routing from RNOs.
>      
> Escalation of CWIX  USA connectivity to CWIX Managing Director (initial 
> response due Friday 26/9/97).
>      
>      
> INTERMEDIATE TERM (within 6 months)
>      
> Increase of UUNet bandwidth by 8M, scheduled for implementation in 
> October 1997.
>      
> Provision of additional 12M bandwidth from new supplier, currently 
> scheduled for 12/97, terminated in the USA.
>      
> Provision of Optus routers in USA, and local loop connectivity to Tier 1 
> providers. One router already on site and awaiting installation, testing and 
> commissioning.
>      
> Provision of satellite capacity for non-time critical applications. 
> Testing presently in progress and initial results and very good.
>      
> Introduction of contiguous bandwidth in order to develop DS3 (45Mbps) 
> international connections.
>      
>      
> LONG TERM (>6 months)
>      
> Establishment of regional connectivity directly to important areas of the 
> world.
>      
> Further development of DS3 (45Mbps) international connections.
>      
> OTHER INITIATIVES
>      
> Optus has redesigned and better integrated its internal processes to 
> ensure improved linking of AARNet forecasts with network deliverables. This h
> as 
> been achieved by reassignment of management responsibilities, and  improvemen
> ts 
> in work assignments.
>      
> In conjunction with the AVCC, Optus will publicize the above planned 
> network improvements to RNOs and Universities.
