In wavelength-routed optical networks, the high-delay introduced by the optical switching fabric for resource reservation increases critically the lightpath setup delay. In order to minimize the setup delay, Generalized Multi-protocol Label Switching (GMPLS) introduced the concept of Suggested Label Object (SL), which allows to start reserving and configuring the hardware with a proposed wavelength from the source node to the destination node. This solution is not optimal in wavelength selective networks (WSN) (i.e., without wavelengths converters). The need of guaranteeing the wavelength continuity constraint for end-to-end optical connections, combined with the lack of global wavelength-based link information (the source node is not aware of which wavelengths are available on each link), makes that the likelihood of establishing a lightpath using the proposed suggested label may be minimum. In this article, we propose an enhancement to the current GMPLS RSVP-TE signaling protocol with offset time-based provisioning that minimizes the lightpath setup, improving the overall network performance in terms of blocking probability and setup delay. Experimental performance evaluation has been carried out in ADRENALINE testbed, a GMPLS-based intelligent all-optical transport network.

This work focuses on the problem of dynamic provisioning of bidirectional connections in all-optical WDM networks. In absence of wavelength converters, each data path forming a bidirectional lightpath needs to use the same wavelength on every link of the entire route (i.e., wavelength continuity constraint). Though existing GMPLS framework faces up the bidirectional lightpath establishment, it fails with high probability under the WCC restriction. Therefore, a distributed and dynamic routing and wavelength assignment (DRWA) algorithm is proposed to perform bidirectional path computation taking into account global wavelength network utilization. By doing so, the algorithm is capable to meet efficiently with the WCC each particular connection request. The performance of the proposed algorithm is experimentally evaluated and compared in the ADRENALINE testbed using a traditional bandwidth-based algorithm as a benchmark. The results are expressed in terms of connection blocking and setup delay for different traffic loads.

“…For this metro scenario, transmission techniques for core networks are not necessary, but a more cost-effective solution must be considered. In this paper, we propose a cost-effective elastic OFDM BVT using direct detection (DD) for rate and distance adaptive transmission in flexi-grid metro networks and experimentally validate it in the ADRENALINE testbed 1 . The rate/bandwidth can be varied by software with fine granularity, selecting the suitable modulation format and number of OFDM subcarriers.…”
