[AusNOG] News: Telstra to clamp down on peer-to-peer

[Terry Sweetser (SkyMesh CTO)]

So y'all aware, NBN has traffic classes:  TC1 and TC4 are available 
now.  In dot1Q land they are cos 5 and cos 0 respectively.

Obviously, TC1 is aimed at voice, and you only get 150kbps of it on any 
given fibre or wireless service.

The rebuttal here is that NBN does not automatically assign traffic to 
TC1, in fact the end points at each end of the NBN need to mark the 
traffic correctly to use TC1.
(One of these end points is the ATA included in the fibre NTD used by 
NBN for voice.)

At the NNI/CVC level, it is up to the RSP to mark customer traffic 
entering the NBN as TC1, and at the NTD, the customer CPE must mark 
accordingly.

While transiting NBN, your TC1 packets are a lot safer from congestion 
management than TC4 packets.

At NBN ingress, CPE and RSP bridges should queue 'eligible TC1' packets 
correctly to ensure they don't drop due to lack of NNI/CVC bandwidth.
