If the importance of the traffic exchanged increases (eg increasing VoIP peering), maybe provisioning two links for peering is a good idea. The other thing that might be interesting to consider in some environments (eg peering through a switched infrastructure) is faster convergence. Pairing BFD with eBGP would enable much faster detection of the loss of connectivity. Now seems like a good time to raise it.

Would be expect this would be more complex than straight QoS and BW arrangements. Just a thought. On Wed, June 27, 2007 2:20 pm, Joe Abley wrote:

Basically Telecom saying they would establish 29 regional points of interconnection, where providers could interconnect with them.
The article mentions paying for a circuit into Telecom's network, with them reciprocating a circuit back (in the case of an ethernet interconnect, does this mean paying half each?).
I'm a little confused by some of the terminology being used and exactly what that will mean - hopefully when a few more specifics come out it will make a little more sense. In the case of reciprocating a circuit back, does that mean you end up with two circuits between parties? Or you end up with two unidirectional circuits? I suspect this in fact means each party is responsible for getting to the
peering
point, wherever that may end up being.
It seems to me that this kind of arrangement (sharing the cost of circuits) is very much the way that voice interconnects between carriers were arranged back when I had occasion to care about such things (via POIs, POLIs and SPOLIs).
I assumed that the terminology was the result of the regular voice interconnect guys writing the press release, and that it probably bore little resemblance to anything that might be used in practice.
(You'll know I'm right if you start to see peering ratios expressed in erlangs :-)
