[AusNOG] Scaling beyond 1Gbps transit

[James Braunegg]

Dear James

We had this very debate back in 2010 we were using Cisco 7200 G2 at our pop sites and they would just die under pressure .... Even more so when you started to flow traffic.

We looked at the Cisco ASR, Brocade MLXe and Juniper MX routers all of which were stupidly large from a capacity point of view .... We ended up choosing the Brocade MLXe platform and it's been a choice which I'm very happy with..... Lots of ports, lots of capacity and huge amounts of performance.

That being said as mentioned you also have the Brocade CER RT which is a 1RU box like a MLXe but cut down in physical size single routing engine but still supports 4 x 10gbit interfaces and 1.5 million routes.

Kindest Regards

James Braunegg

Since a bunch of people chipped in with the ASR option, which are great and can be quite attractive with the lower end/priced bundles..... a few words of warning.

They're complicated boxes so make sure you're familiar with the ASR architecture including what components exist within each box. In particular what components have their own discrete memory; along with what those memory requirements will be within your particular network using your particular configuration.

e.g. If you take MPLS all the way to the edge and are encapsulating a full Internet routing table that will impact memory requirements within the ESP. There are workarounds but on 1K consider an ESP 10G at a minimum.

There are some ASR1K bundles you can get that include reasonably priced 10Gb ports.

If you don't get those ports via the bundle price, then yes, they blow the cost out of the water. I've seen some scenarios where it's almost worth buying a 1001 just to get bundled 10G adapters, that you then use somewhere else.
