A Novel Approach to Quality of Service Provisioning in Trusted Relay Quantum Key Distribution Networks
In recent years, noticeable progress has been made in the development of
quantum equipment, reflected through the number of successful demonstrations of
Quantum Key Distribution (QKD) technology. Although they showcase the great
achievements of QKD, many practical difficulties still need to be resolved.
Inspired by the significant similarity between mobile ad-hoc networks and QKD
technology, we propose a novel quality of service (QoS) model including new
metrics for determining the states of public and quantum channels as well as a
comprehensive metric of the QKD link. We also propose a novel routing protocol
to achieve high-level scalability and minimize consumption of cryptographic
keys. Given the limited mobility of nodes in QKD networks, our routing protocol
uses the geographical distance and calculated link states to determine the
optimal route. It also benefits from a caching mechanism and detection of
returning loops to provide effective forwarding while minimizing key
consumption and achieving the desired utilization of network links. Simulation
results are presented to demonstrate the validity and accuracy of the proposed
solutions.Comment: The article under the review in IEEE/ACM Transactions on Networking
