The current generation 5G and ultra-high-speed networks have strict requirements of low latency performance from the transmission network. Proposed herein is a mechanism to ensure that a Generalized Multiprotocol Label Switching (GMPLS) Optical Transport Network (OTN)-based transport network considers latency as one of the criteria to establish and reroute OTN Optical Channel Data Unit (ODU) Label Switched Path (LSP) circuits. This will ensure that clients receive the ODU path with latency criteria that satisfy the clients’ specified acceptable limits.
