The introduction of optical-circuit-switches (OCSs) has been considered as key to cost-effectively scale the AI interconnect infrastructure. However, current AI interconnect is realized by vendor-proprietary hardware and software solutions and we thus lack the interoperability and openness in this domain. This could lead to increase both capital and operational expenditure for GPU service providers. Recently, IOWN Global Forum started an activity on defining a reference implementation model for the AI interconnect infrastructure. Among several study items on that activity, this presentation introduces an open network controller framework for managing the AI interconnect with multi-vendor OCSs.
