[AusNOG] 40G/100G

[Ankit Agrawal]

Agree with all of you.

For now, using few 10GEs in LAG is fine and that mitigates the expense for
a 40GE port which I agree is more popular in the server infrastructure and
not so common in the ISP space when you need high throughput. Most ISP
vendors prefer to go to 100GE as opposed to 40GE which makes sense. The
reason I put 40GE as an option in my requirement for port density and
scalability was around server network and connectivity to internal
infrastructure and not so much on the transit provider path.

The price for 100GE was significantly high before but has dropped now and
probably in few month's time, it will come down enough to justify
upgrading to 100GE.

General consensus I guess will be to continue doing 10GE LAG and later use
40GE for server infrastructure and 100GE for transit side and even
internal connectivity if you can.

Ankit.
