Performance of a Source-Based Interdomain Provisioning Solution for Multidomain SDOTN

This paper designs and analyzes the performance and scalability of a source-based interdomain provisioning (SIP) solution for multidomain software-defined optical transport networking (SDOTN). The challenge of this paper is to design SIP to solve the processing complexity of distributed per-domain provisioning (DPP) while eliminating the traffic and processing concentration of hierarchical interdomain provisioning (HIP). By using mathematical models, the throughput and latency of the proposed solution were evaluated. The numerical results prove that the proposed SIP improves the scalability more than ten times compared with DPP and around twice that of HIP.
