From b44e9bc90b634b07d5f93a731a95028adc73bcbc Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Fri, 19 Feb 2016 09:06:23 -0500 Subject: Serialize and upload the data plane node graph Include node names and graph arcs. Prep work for uploading node runtime data, so the latter can be reported in a comprehensible manner.
