Hello! Somebody definitely should build full feature router with DPDK/netmap/pf_ring :)
I have finished detailed performance tests for all of them and could achieve wire speed forwarding (with simple packet rewrite and checksum calculation) with all of they. I.e. I could process 10GE and 14.6 mpps (64byte packets) on very cheap i7 3820 with single intel X540 NIC (total cost about $ 800) with CPU 70% load. But full BGP routing is a challenge but could be implemented with existing approaches like DXR: http://info.iet.unipi.it/~luigi/papers/20120601-dxr.pdf Cheers!
