From the draft paper: "It should be noted that the Snabb project [16] has similar design goals, ixy tries to be one order of magnitude simpler than Snabb. For example, Snabb targets 10,000 lines of code [15], we target 1,000 lines of code and Snabb builds on Lua with LuaJIT instead of C limiting accessibility." Snabb aims at practicality while Ixy aims at education, as I understand it, though I haven't read either one yet.
