But I think a clarification on Baldur's speed requirements is needed. He indicates that there are a bunch of locations: do each of the locations require 10G throughput, or was the throughput defined for all sites in aggregate? If the sites indivdiually have smaller throughput, the software based boxes might do, but if that is at each site, then software-only boxes may not handle the throughput.
We have considerably more than 10G of total traffic. We are currently transporting it all to one of two locations before doing the BNG function. We then have VRRP to enable failover to the other location. Transport is by MPLS and L2VPN. I set the goal post at 10G per server. To handle more traffic we will have multiple servers. Load balance does not need to be dynamic. We would just distribute the customers so each customer is always handled by the same server. 10G per server translates to approximately 5000 customers per server (2018 - this number is expected to drop as time goes). I am wondering if we could make an open source system (does not strictly have to be Linux) that could do the BNG function at 10G per server, with a server in the price range of 1k - 2k USD. For many sizes of ISP this would be far far cheaper than any of the solutions from Cisco, Juniper et al. Even if you had to get 10 servers to handle 100G you would likely still come out ahead of the big iron solution. And for a startup (like us) it is great to be able to start out with little investment and then let the solution grow with the business. Regards, Baldur
