For the Destination Initialed Reservation in PCE-based Wavelength Switched Optical Networks using the distributed wavelength assignment scheme, the establishment of a lightpath might be blocked because of the contention for the same wavelength between two or more concurrent requests traversing the same links, although there might be enough wavelength resource available. In order to reduce the blocking...
For the Destination Initialed Reservation (DIR) in Wavelength Switched Optical Networks (WSONs) using the distributed wavelength assignment scheme, the establishment of a lightpath might be blocked because of the contention for the same lambda between two or more concurrent requests traversing the same links, although there might be enough available lambda resource. In order to reduce the blocking...
Proposed in this paper is a backup-reservation-based wavelength assignment (BRWA) scheme for wavelength switched optical networks (WSONs). The rationale behind the idea is to reserve a backup lambda in addition to the primary one for a lightpath if the number of the available lambdas can meet certain constraints. Therefore a threshold is defined to determine whether to reserve a backup lambda according...
Proposed in this paper is a PCE-Assistant Collision-Avoiding Wavelength Assignment Scheme (PACAWAS) for transparent Wavelength Switched Optical Networks (WSONs) to solve the resource contention problem in distributed wavelength assignment scenario. In this scheme, several extensions are made to the GMPLS (Generalized Multi Protocol Label Switching) signaling, and a wavelength selection assistant unit...
