Hi Mark. The current implementation has the PREQ mechanism and implements on demand patch selection. The draft indeed specifies that the routing protocol has both on demand and proactive path selection and proactive can be implemented using the PREQ mechanism or the RANN mechanism. The current implementation does not have the RANN mechanism so perhaps implementing proactive path selection using PREQ would be a good way to start. -Andrey On Mon, Jan 26, 2009 at 5:48 AM, Mark Ryden <markryde@xxxxxxxxx> wrote: > Hello, > - Mesh routing in Linux implements the hwmp protocol. > - I had delved into the mesh code in the latest git wireless-testing tree. > - The part for on demand routing is implemented via the > mesh_path_start_discovery() and other methods and via > sending/receiving the MPATH_PREQ /MPATH_PREP/MPATH_PERR messages (see > mesh_hwmp.c) > > - My question is about proactive routing: First, AFAIK, proactive > routing is mandatory in hwmp (the name hybrid suggests it, proactive > routing and on demand > routing).
