Chat-Driven Interface for Virtual Network Reallocation

This paper addresses the system design for virtual network services, particularly focusing on virtual machine (VM) services. The VM service requires users to define a substantial number of specifications, such as CPU resources and latency bounds, as a prerequisite. This process is challenging for nonprofessional users and inefficient even for professional users. Users need to clearly understand the specifications they need and report their requirements to the service manager, which demands a high level of knowledge and experience of a system engineer. To make the system more accessible to users, we propose a framework that enables interaction with the virtual network service through natural language (NL) inputs from the users. The framework employs NL models to interpret user requests in NL format into service specifications to determine the specificationdependent optimal virtual network allocation. We demonstrated the effectiveness of the proposed framework through numerical experiments, which show that the user requests in NL are accurately interpreted and incorporated into the virtual network allocation.
