[AusNOG] 1+1 ports

[Matthew Moyle-Croft]

It's probably more a commercial issue:

(a) Duplicating ports on the same switch on your provider's end doesn't really provide much protection
(b) It's hard to deliver this without giving you "free" bandwidth (ie.  how do you prevent you bursting on both ports simultaneously?)

I don't see mitigating a switch failure at your end is that useful unless you've actually built redundancy elsewhere.   If you think a switch failure at your end is more likely than anything else then I'd probably choose a different switch/vendor!

Hi,

I’m trying to find out if there are any carriers out there who provide 2 ports at each end for a point to point Ethernet circuit? (VPLS)

I’m trying to build some redundancy into a network, I’ve asked our carrier if they can provide 2 ports at each end  to mitigate a switch failure on our end and they’ve essentially said no, buy another service identical to what you’ve already got if you want to do that. I don’t need anymore bandwidth, just separate physical interfaces to run on.

Speaking to other people in the industry, it seems the norm for carriers to provide the service over 2 physical ports if requested (obviously for a price). I’m curious if other people have been able to get this configuration on PTP Ethernet circuits ?

Just chasing info at the moment, possibly I need to jump ship to get what I want, or maybe I’m just dreaming and it’s a technical reason why it cant be done.

Regards,

Daniel
