I don't see TCAM listed either, but as large as HP is I assume they can afford and use TCAM in their larger routers. On Sat, Mar 12, 2016 at 1:30 PM, William Herrin <bill () herrin us> wrote:

The HSR 6602-XG will push 15 Mpps with routing table sizes of 4mil (ipv4) and 2mil (ipv6) there is no additional licensing for any feature you want to use. With respect to implementation I have alwaysfeltif you understand the protocol who gives a damn about the syntax... TheMSR4060 will handle 36 Mpps with table sizes of 1mil (ipv4) and 1mil (ipv6). Either solution will be cost effective.Hi Colton, My bet is that there's no TCAM. That or they're being cagey about their hardware architecture since I can't find a single document about the router that even mentions TCAM. Instead I'd bet they're doing software routing (radix tree) spread over "32 hardware threads" and as long as the bulk of your destinations are in small enough parts of the tree to fit cleanly in to the processor caches you'll get "up to 15 Mpps". http://h20195.www2.hp.com/v2/GetDocument.aspx?docname=c04111430&doctype=quickspecs&doclang=EN_US&searchquery=&cc=us&lc=en If I'm right (I'm making guesses after all) then you should compare HP's offering with software-based routers from other vendors rather than comparing against routers which have a hardware fast path.
