Hi everybody! I got the following question. When I use linux as a router (via ip forwarding) what kernel variables (maybe some queues?) represent the closest analogue of usual hardware router input and output buffers? May this be, say, backlog queue or something else? The things I need to get are the sizes and loads of that buffers during transmission. I know about variables such as sk->sk_rcvbuf and sk->sk_rmem_alloc but they are not used during ip forwarding as the socket (i.e. sock structure) is not even being created for that purpose. As far as I understood these variables in sock structure are mostly used for tcp-level packet processing and they represent the values written in files like /proc/sys/net/core/wmem_default etc. (please correct me if that's wrong), but nevertheless maybe I also can use these values for "routing" buffers (i.e. on ip level)? thanks in advance, Serge MIPT Moscow, Russia - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
