Delay Tolerant Network (DTN) routing addresses challenges of providing end-to-end service where end-
to-end data forwarding paths may not exist. The performance of current DTN routing protocols is often
limited by routing metric ``staleness", i.e., routing information that becomes out-of-date or inaccurate
because of long propagation delays. Our previous work, ParaNets, proposed a new opportunistic network
