    Description

      There's a recent discussion on wc-discuss:

      It's a frequently asked question, and should deserve a place in the manual.

          This is where I am right now.

          My idea was to explain LNET routing in more detail. Once I picked this task up, I felt that LNET itself needed more explanation. So currently, I am working on improving Chapter 2 and making a good deal of addition to chapter 9. Most of that is done. I will try to submit these changes, hopefully by next week.

          Now as far as, LNET/LND credits and flow control is concerned, we have seen the effects of tweaking LNET kernel module paramters, however, we unfortunately haven't been able to simulate or create a complex enough test bench to actually see the results of tweaking respective LND kernel module parameters . Hence, I do not have complete clarity to write on this subject.....yet.

          I have also noticed the recent addition of a new chapter on this topic. I will add what I can to this new chapter.

          If you would like to assign the ticket, please do so. I will try and contribute as much as I can.
