Establishing end-to-end quantum connections requires quantified linkcharacteristics, and operations need to coordinate decision-making betweennodes across a network. We introduce the RuleSet-based communication protocolfor supporting quantum operations over distant nodes to minimize classicalpacket transmissions for guaranteeing synchronicity. RuleSets are distributedto nodes along a path at connection set up time, and hold lists of operationsthat need to be performed in real time. We simulate the RuleSet-based quantumlink bootstrapping protocol, which consists of recurrent purifications andlink-level tomography, to quantify the quantum link fidelity and itsthroughput. Our Markov-Chain Monte-Carlo simulation includes various errorsources, such as the memory error, gate error and channel error, modeled oncurrently available hardware. We found that when two quantum nodes, each with100 memory qubits capable of emitting photons ideally to the optical fiber, arephysically connected with a 10km MeetInTheMiddle link, the Recurrent Singleselection - Single error purification (RSs-Sp) protocol is capable of bringingup the fidelity from an average input $F_{r}=0.675$ to around $F_{r}=0.865$with a generation rate of 1106 Bell pairs per second, as determined bysimulated tomography. The system gets noisier with longer channels, in whichcase errors may develop faster than the purification gain. In such a situation,a stronger purification method, such as the double selection-basedpurification, shows an advantage for improving the fidelity. The knowledgeacquired from bootstrapping can later be distributed to nodes within the samenetwork, and used for other purposes such as route selection.
