Several years after being standardized, no interoperable implementations of BLSR/MSpring from different vendors can be found. The best way to ensure interoperability is to conduct trials involving multiple vendors to uncover problems in early specifications and promote multivendor interworking. In this regard, some significant optical control plane interoperability trials have occurred:

  • OIF UNI interoperability trial: In the summer of 2001, the OIF sponsored an UNI interoperability trial involving twenty-five different vendors. The vendors underwent interoperability testing in the ...
