Summary:
|
With the rapid development of Quantum Key Distribution Network (QKDN) technology, the QKDN increasingly expands the deployment scope, from some specific lines to a network. Meanwhile, more and more applications adopt the cryptographic services provided by the QKDN, such as the voice service based IMS, video conference and massive data transfer. The QKDN is becoming a kind of cryptographic infrastructure.
However the circumstances of the enterprise customers usually are complicated. On one hand, the enterprise customers may have multiple geographically distributed sites which connect with each other. On the other hand, the enterprise customers may have multiple applications using the QKDN services which have different QoS requirements, specifically when the enterprise customers are kind of security application service providers. In order to meet the diverse requirements of enterprise customers or security application service providers, providing the customers with customized QKDN resources and unified resource description in the form of QKDN slices is becoming a promising method. QKDN slice, driven from the service operational perspective, could be considered as a logical QKDN that provides specific QKDN capabilities and characteristics. From a service perspective, enterprise customers of QKDN slices are not affected by changes in other QKDN slices. The control, management and orchestration functions of QKDN defined in the Recommendation ITU-T Y.3800 series provide the basic capabilities such as routing control, session control, quality of service (QoS), FCAPS management and multi-layers orchestration. However, how to implement the QKDN slice requirements derived from the customers to the unified QKDN resource description and QKDN control, management and orchestration operation need to be further studied.
Therefore, it is proposed to start a new work item to study the quantum key distribution network slicing, specifically on the requirements, framework, and operational procedures.
