    Design Documents

    Here are a few design notes that I had scribbled while laying out the initial design of zmpls.

    Disclaimer : Like any open source developer I suggest to read the source code for correct
                      info. You will find that lots had changed in the code since the initial design notes.
                      These notes can't be taken as absolute reference materials for the zMPLS source
                      code. May be I will be able to write proper functional and design doc for the
                      upcoming version zmpls-1.0 if I get time from my assignments for which I get
                      paid by my employer :-). However I don't promise it.

   rsvpd : rsvpd design notes can be found here (RSVPTED_Design.txt).  The code has gone
               through lots of changes since the first verisin -0.1a. I have tried to improve scalability
               issues with better timer management and path/resv state lookups in the latest verisions. 

   ldpd   : ldpd design notes can be found here (LDPD_Design.txt). As usual like rsvpd it has
              gone through changes.

   zmpls : zmpls design notes can be found here (ZMPLS_Design.txt).
