I would like to share this pre-idea and to receive your opinions. I have one question here. Why should it be limited to UDP... (or whatever protocol)? Are we going to loose something, if we, say, create special node for 'netgraph tunneling' (so that it may ot may not be included into a running kernel) then connect this node to another one, which will be used for 'transport' layer. Such a node could possibly be used to encode/decode the inter-netgraph messages. Other nodes' names then should include the transport layer address. This way I think we won't get limited to one protcol... = Comments? > >- Encode control messsages in their ASCII forms for transit > across the network > >- Pick a well known UDP port to be used for netgraph messages > and data packets > >- Create a node type that could listen on this port (using ng_ksocket) > and do the required encoding/decoding. > >-Archie > >________________________________________________________________________= _ >Archie Cobbs * Packet Design * >http://www.packetdesign.= com ____________________________________________________________________ Get free email and a permanent address at http://www.netaddress.com/?N=3D= 1 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
