dc.description.abstractThe exposure of massive internet growth urge us for finding substitute methods for the fast communication in data center networks. The only panacea for the data centers is the deployment of Optical burst switching (OBS). It evolves as a near-future deployment choice to aid dynamic and bandwidth intense traffic difficulties in Data centers. Optical Burst Switching (OBS) promise an efficient support for bursty traffic with high resource utilization without buffer in the Wavelength-division multiplexing (WDM). In order to establish a session in the heterogeneous environment of data center networks (DCNs), OBS need full Wavelength of bandwidth Assigned. The wavelength of intermediate hops also should be free for the circuit establishment. Connection may not be established when the intermediate hops utilize its full wavelength of assigned bandwidth. This is what blocking in OBS. Overall blocking probability have to be minimized for the reliable communication. In this paper, an enhanced analytical model is proposed for the reduction of blocking probability with the use of Controller Dependent Dual Layer Architecture (CDLA). Enhanced Erlang B is used to assess the required optics between core switches and TOR switches of the datacenter Networks. Blocking probability differs based on the allocated wavelength and load employed in the network. The proposed model cover two iterations. The process starts with the offered loads and the second iteration dealt with allocated resources. We model our architecture using green cloud simulator using NS2 with varying workloads through different burst rates by deliberating various edge-to-core network over offering proportion for examining the accomplishment of representations beyond usage patterns. The effects exhibits that the suggested model shows prominent enhancement in route scheduling and comparable achievement in terms of minimized blocking probability relevant to conventional OBS techniques.en_US
