  To realize a global quantum Internet, there is a need for communication
between quantum subnetworks. To accomplish this task, there have been multiple
design proposals for a quantum backbone network and quantum subnetworks. In
this work, we elaborate on the design that uses entanglement and quantum
teleportation to build the quantum backbone between packetized quantum
networks. We design a network interface to interconnect packetized quantum
networks with entanglement-based quantum backbone networks and, moreover,
design a scheme to accomplish data transmission over this hybrid quantum
network model. We analyze the use of various implementations of the backbone
network, focusing our study on backbone networks that use satellite links to
continuously distribute entanglement resources. For feasibility, we analyze
various system parameters via simulation to benchmark the performance of the
overall network.
