TLDR
This document provides mechanisms to support distributed wavelengths assignment with a choice of distributed wavelength assignment algorithms.Abstract:
This document provides extensions to Generalized Multiprotocol Label
Switching (GMPLS) signaling for control of Wavelength Switched Optical
Networks (WSONs). Such extensions are applicable in WSONs under a
number of conditions including: (a) when optional processing, such as
regeneration, must be configured to occur at specific nodes along a
path, (b) where equipment must be configured to accept an optical
signal with specific attributes, or (c) where equipment must be
configured to output an optical signal with specific attributes. This
document provides mechanisms to support distributed wavelength
assignment with a choice of distributed wavelength assignment
algorithms.read more

Handling race conditions among bidirectional LSP requests via WA-method-TLV in GMPLS WDM networks
Yue Fei,Yamini Jayabal,Zhen Lu,Miguel Razo,Marco Tacca,Andrea Fumagalli,Rongqing Hui,Gabriele Galimberti,Giovanni Martinelli +8 more
TL;DR: In this paper, the authors define three types of race conditions that may occur while attempting to reserve optical circuits in GMPLS WDM networks and investigate the effect on network blocking by race condition type and explain how to use an existing TLV in the IETF RSVP signaling to inform the destination node of a potential race condition occurrence.

Optical power control in translucent flexible optical networks with GMPLS control plane
TL;DR: A new routing algorithm and protocol extensions are proposed to take into account power and regeneration information in the GMPLS control plane of translucent networks, and thus, the power adaptation process is adapted to this kind of network.

PCE-based vs. distributed set up of bidirectional lightpaths in GMPLS-controlled optical networks
TL;DR: A PCE-based architecture for bidirectional lightpath set up in GMPLS-controlled optical networks is proposed and evaluated that strongly improves the performance of the distributed architecture with both standard and enhanced signaling schemes.
RSVP-TE Signaling Extensions in Support of Flexi-Grid Dense Wavelength Division Multiplexing (DWDM) Networks
TL;DR: This memo describes the extensions to the Resource Reservation Protocol - Traffic Engineering (RSVP-TE) signaling protocol to support Label Switched Paths (LSPs) in a GMPLS-controlled network that includes devices using the flexible optical grid.
