Two types of control architectures for control plane of optical burst switching networks have been defined in literature; first one is distributed with link-based reservation and second one centralized with end-toend reservation. In this paper we propose a new hybrid control architecture which combines the best features of both of these architectures such as scalability features of distributed ...

This paper has presented the performance of an optical code division multiple access (OCDMA) system for indoor, short and outdoor applications and the transmission efficiency to be evaluated in order to determine the impact of multi access interference for a given number of users in dense wavelength division multiplexing. Optical code division multiple access is an alternative multiplexing sche...

The Internet is evolving from best-effort service toward an integrated or differentiate service framework with Quality of Service (QoS) assurances that are required for new multimedia service applications. Given this increasing demand for high bandwidth Internet with QoS assurances in the coming years, IP/MPLS based control plane combined with wavelength-routed Dense Wavelength Division Multipl...

According to a historical rule of thumb, which is widely used in routers, the buffer size of each output link of a router should be set to the product of the bandwidth and the average round-trip time. However, it is very difficult to satisfy this buffer requirement for ultra-high-speed dense wavelength division multiplexing (DWDM) networks with the current technology. Recently, many researchers...

We report an industry leading optical dense wavelength division multiplexing (DWDM) field trial with line rates per channel $\ge 1.66$ Tb/s using 130 GBaud dual-polarization probabilistic constellation shaping 256-ary quadrature amplitude modulation (DP-PCS256QAM) in a high capacity data center interconnect (DCI) scenario....

Wide free spectral range (FSR) optical filters are very much essential for modern commercial Dense Wavelength Division Multiplexing(DWDM) technique.Performance of a serially coupled integrated optic triple ring resonator (TRR) which can be used as optical filter has been investigated in this article. Delay line signal processing and Mason’s rule have been used to analyze the TRR architecture. F...

Daniel Stevenson MCNC 3021 Cornwallis Road P.O. Box 12889 Research Triangle Park, North Carolina 27709 Abstract. We present a formal protocol description for a just-in-time (JIT) signaling scheme running over a core dense wavelength division multiplexing (DWDM) network that utilizes optical burst switches (OBSs). We apply an eight-tuple extended finite state machine (EFSM) model to formally spe...

Optical communication systems and networks will continue to play a significant role in the development and deployment of emerging network infrastructures. These networks are expected to support the diverse requirements of a broad range of existing and future applications. To accommodate this wide spectrum of applications, network infrastructures are evolving rapidly in terms of technology and a...

A new materials group to implement dense wavelength division multiplexing (DWDM) in Si photonics is proposed. A large thermo-optic (TO) coefficient of Si malfunctions multiplexer/demultiplexer (MUX/DEMUX) on a chip under thermal fluctuation, and thus DWDM implementation, has been one of the most challenging targets in Si photonics. The present study specifies an optical materials group for DWDM...
