Hi ,
      Do we use GMPLS signaling protocol for configuring Sonet Rings ( UPSR
/ BLSR ( 2 fiber/4 
      fiber ) ? 

      I was going  through certain white papers where there was a mention
that GMPLS is used as 
      a signaling protocol for provisioning mesh topologies only
.Traditional Sonet rings will be
      replaced by mesh topologies in future .
 
      But there is a section 12.( LSP protection and restoration) in GMPLS
Architecture which says
      that " Both mesh and ring like topologies are supported "

      How do we provision nodes in Sonet ring using GMPLS ?
      Or GMPLS has been designed to provision mesh topologies only. 

Regards ,
Manoj
