[AusNOG] 1+1 ports

[Shane Short]

I find it interesting Nextgen will offer this for 'Internet' services, but no mention of it being available for P-t-P: http://www.nextgennetworks.com.au/7629%20Nextgen%20Shadow%20DataSheet%20D11-2.pdf

It addresses Matthew's concern of using both ports simultaneously with the following clause:
"Low usage levels are allowed on the shadow link in support of routine keep-alive and reasonable link availability testing. Any traffic profile where the 98th percentile utilisation of both the upstream and downstream directions is at or below 100kb/s will not incur excess usage charges."

Dan: perhaps ask nicely to see if they'll do something like this for you?

I don’t need anymore bandwidth, just separate physical interfaces to run on.
