Which categories of protocols are included in the GMPLS technology?
Correct Answer: D
Explanation The GMPLS technology includes three categories of protocols: routing, signaling, and link management. Routing protocols are used to exchange information about the network topology, resources, and constraints among the nodes. Signaling protocols are used to establish, modify, and release Label Switched Paths (LSPs) across the network. Link management protocols are used to verify the connectivity and status of the links between adjacent nodes. References : Nokia GMPLS-controlled Optical Networks Course | Nokia, 3. GMPLS - Nokia
