Wavelengths will become a new instrument for settlement and exchange, eventually leading to future markets in wavelengths. This may allow smaller ISPs and research and education networks to route around large ISPs that dominate the Internet by massive direct peerings with like-minded networks. Bill St. Arnaud saw ITN as a first step to a global matrix of OBGP wavelengths. In this, ITN could support international transit. Eventually layer-3 transit could be replaced by wavelength transit, using OBGP for wavelength management.
Discussions are underway with international carriers to acquire initial wavelengths.
