   This surprises me.   
      
   I can get many L3 switches from multiple vendors that support 10 Gbps.   
   I can get quite a few traditional routers from most of the same vendors   
   that support 10 Gbps.   
      
   I can get some L3 switches from multiple vendors that support 25 / 40 /   
   50 / 100 Gbps interfaces.   
      
   I can get some traditional routers with some of those interfaces.   
      
   Once you start crossing 10 Gbps interfaces, it becomes more difficult   
   for a Linux / *BSD box to pass packets fast enough.  But there are   
   people working on it and have achieved the 10 Gbps mark.  I expect that   
   they have gotten faster, particularly with DPDK.   
      
   Cisco Catalyst 4900M / Nexus 3000 line / NCS 5000 line all come to mind   
   at 10 Gbps, some of which can do faster.   
      
   Juniper QFX 5100 comes to mind.   
      
   We use some model of Juniper traditional router that has multiple 100   
   Gbps line cards in them.   
      
   I feel like there are more than "a few" choices.  Perhaps the limiting   
   factor that I'm not taking into account is "infrastructure routers".   
      
   Please elaborate on what you mean Robert.
