Service-Oriented Multigranular Optical Network Architecture for Clouds

This paper presents a novel service-oriented network architecture to bridge the informational gap between user applications and optical networks providing technology-agnostic multigranular optical network services for clouds. A mediation layer (service plane) between user applications and network control is proposed to facilitate a mapping process between user application requests and the network services. At the network level, a multigranular optical network (MGON) is proposed and implemented to support dynamic wavelength and subwavelength granularities with different transport formats [optical burst switched (OBS), optical burst transport (OBT)], reservation protocols (one-way, two-way), and different quality-of-service (QoS) levels per service type. The service-oriented multigranular optical network has been designed, implemented, and demonstrated on an experimental testbed. The testbed consists of service and network resource provisioning, service abstraction, and network resource virtualization. The service-to-network interoperation is provided by means of a gateway that maps service requests to technology-specific parameters and a common signaling channel for both service and network resource provisioning

Optical network technologies for future digital cinema

Digital technology has transformed the information flow and support infrastructure for numerous application domains, such as cellular communications. Cinematography, traditionally, a film based medium, has embraced digital technology leading to innovative transformations in its work flow. Digital cinema supports transmission of high resolution content enabled by the latest advancements in optical communications and video compression. In this paper we provide a survey of the optical network technologies for supporting this bandwidth intensive traffic class. We also highlight the significance and benefits of the state of the art in optical technologies that support the digital cinema work flow

VIDEO STREAMING WITH GIGABIT PASSIVE OPTICAL NETWORK TECHNOLOGY

Perkembangan teknologi berpengaruh kepada kebutuhan user untuk mengakses data lebih cepat, perlahan sistem dengan menggunakan Fiber Optic mulai menggeser posisi kabel tembaga dalam transmisi data karena lebih cepat. Tren user saat ini adalah membutuhkan transmisi data yang lebih cepat dan lebih besar, seperti Video Streaming. Penelitian ini bertujuan untuk membuat system Video Streaming dengan infrastruktur GPON (Gigabit Passive Optical Network). Dalam penelitian dilakukan konfigurasi Video Streaming dengan GPON kemudian juga dilakukan dengan system Ethernet. Keduanya dibandingkan dengan parameter kecepatan dan frame rate untuk Video Streaming. Hasil yang dapat diperoleh dari penelitian dengan menggunakan system GPON adalah kestabilan untuk melakukan Streaming Video dibandingkan Ethernet

HeCSON: Heuristic for Configuration Selectionin Optical Network Planning

We present a transceiver configuration selection heuristic combining Enhanced Gaussian Noise (EGN) models, which shows a 40\% increase in throughput and 87\% decrease in execution time, compared to only approximate EGN and Full-Form EGN respectively
