Online gamers using Telecom's entry-level Jetstream Starter connection 
are venting about a hardware upgrade that is threatening to end happy 
days of simultaneous web surfing or file downloading during game play.
As part of its move to a "next generation network" Telecom is replacing 
its mix of largely Nokia branded routers with equipment from Juniper 
Networks.
The new routers more effectively handle internet traffic by queueing 
packets of data that cannot be sent through in one go due to the limited 
size of the internet connection at the receiver's end.
etc etc etc

I guess it's a difficult decision, because on one hand, you want to 
buffer the packets that would normally be dropped so that the sending 
end doesn't have to timeout and retransmit and slow things down 
further... this is "a good thing" for TCP traffic, but on the other 
hand, you introduce delay to time sensitive traffic as it has to wait 
for anything in the buffer to empty before proceeding, which can be "a 
bad thing".
If the IP DSCP field is honoured, then realtime traffic could be made to 
jump the queue by having DSCP set to expidited forwarding.. but given 
how paranoid some networking equipment can be, I wouldn't be surprised 
if a packet's DSCP value gets silent cleared as it passes across the 
internet.
Any technical comments or throughts on this from the list ?
