Hi Alex, To answer a previous question (which RFC does the definition come from), I think as you say the original one was from Neighbor discovery. The definition is also present in a number of others RFCs: RFC2460 IPv6 RFC4862 Autoconf RFC3315 DHCPv6 RFC4429 Optimistic DAD RFC4436 Detecting Network Attachment v4 RFC5121 IPv6 over Wimax ...
Best, Julien -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Alexandru Petrescu Sent: jeudi 23 avril 2009 21:24 To: 6lowpan Subject: [6lowpan] link definition of rfc4861 to cover wireless non-transitive links as well Previous discussion indicated that link definition of RFC 4861 "Neighbor Discovery for IPv6" is pertinent to 6LoWPAN. I agree with it and suggest the following 6LoWPAN definition: link - a communication facility or medium over which nodes can communicate at the link layer, i.e., the layer immediately below IP (each node can communicate to each other in this medium). Examples are Ethernets (simple or bridged), PPP links, X.25, Frame Relay, wireless links or ATM networks as well as Internet-layer (or higher-layer) "tunnels", such as tunnels over IPv4 or IPv6 itself. This is a slightly modified definition of the link defined in RFC4861, in order to cover also the wireless links. Wireless links may be non-transitive (node A communicates at link layer to both B and C yet B and C are not on the same link). Hidden terminal problem in wireless communications is described in [reference to individual draft in AUTOCONF] draft-baccelli-multi-hop-wireless-communication-02 What do people think about using this link definition in 6LoWPAN?
