Yes, it does. If we want a full asymmetric routing we have to retouch this RFC: http://lab.dyne.org/Ntk_bandwidth_measurement The asymmetric routing was never taken into account, because we worked mainly on wifi and direct links. In the asymmetric routing you need to optimize the upload routes (we are assuming that the upload bw is <= dowload bw), f.e: 1. __ <___<___<__ / \ A B \_____>____>___/ 2. `A' can use the route `1' to send packets to `B', while `B' uses the route `2'. In the current implementation of the QSPN, it is the contrary: A knowns the best route from B to A, while B knowns the best route from A to B. In conclusion: it maybe be a new nice TODO to work on ^_- ~> - 2 - Ntk models the net as made of point-to-point ~> links while a traditional LAN, Ethernet or Token ~> Ring, is just a single multi-point link. ~> So a LAN is modeled as a full connected mesh of ~> logic point-to-point links. ~> Right? Yes, in a wired LAN every node is just connected to the all the others. It is not necessary to turn every computer of the LAN in a Netsukuku node: you can use one of them as a Netsukuku gateway and assign private IPs to the others (like it currently happens with the Internet). ~> The question is: does Ntk assigns addressies to ~> nodes or to node-link connections as IP? Each node has a unique IP address. The IP is choosen randomly from the range of available IPs of its group node. CIDR routing is used to create routes which directs the packets to entire gnodes.
