Colleagues, I have a proposition on changing the behavior of ARP retransmitting. Currently we after sending several ARP requests, sending ARP requests for given IP is suppressed for some interval (by default 20 seconds). Probably this feature was designed in early 90th, when sending one additional broadcast packet was an expensive thing. I suggest to keep sending ARP requests while there is a demand for this (we are trying to transmit packets to this particular IP), ratelimiting these requests to one per second. This will help in a quite common case, when some host on net is rebooting, and we are waiting for him to come up, and notice this only after 1 - 20 seconds since the time it is reachable. Any objections? -- Totus tuus, Glebius. GLEBIUS-RIPN GLEB-RIPE
