IOS-XR on ASR 9k and Junos on MX. For our use case, there's no longer anything limiting as compared to those platforms. BGP policy is perhaps not as rich as you might be used to if your experience is with the sort of routers traditionally marketed to service providers, but I'm sure that will get better, and it's probably irrelevant if your policy is fairly static. You are correct that we do collect a lot of flow data, both via sflow and Netflow. We've been able to do everything we need with Arista's sflow implementation.

Ryan,
What routing platform were you coming from before? What features does Arista not have that you find limiting that the old platform did have?
How does Astira's Sflow only compare to having Cisco Netflow or Juniper JFlow for traffic monitoring which I assume Netflix does alot of?

I know Arista is typically a switch manufacturer, but with their recently announced Arista 7500R Series and soon to be announced but already shipping 7280R Series Arista is officially getting into the routing game. The fixed 1U 7280R Series looks quite impressive. The 7500R series is your traditional chassis and line card based solution.
Both of these products have the ability to hold the full internet routing table, and Arista is working on MPLS features. Both of these new

We (Netflix) have been deploying the previous gen (7500E) as edge routers for about two years in high traffic, low route count applications in our CDN, and have been working with Arista for almost as long to improve route scale so that we could turn off all our traditional routers.
The features that enable full routes on Jericho are running in our production network today and we also have the 7500R and 7280R working with full tables.
I can't speak to MPLS, but for our use case (all L3, very high-density 10/40/100G, BGP, IS-IS and light QoS), it's working well.
So, yes, I'd say those two products are quite viable and competitive options in the edge router space.
