Dynamic control to graft and prune optical point-to-multipoint trees was successfully demonstrated in a WSON testbed by utilizing GMPLS signaling extensions. By using wavelength selective switch with variable optical power split function, a power managed P2MP tree could be constructed.
Multi-domain resilient translucent WSONs with distributed GMPLS control and centralized PCE/GMPLS control were experimentally demonstrated and quantitatively compared in terms of lightpath provisioning latency and service disruption time in case of an inter-domain link failure.
Survivability is a key issue in optical grids. In this paper, a resilient Optical Burst Switching (OBS) / Generalized Multi-Protocol Label Switching (GMPLS) network scenario, in which both the protection/restoration in the OBS layer and GMPLS layer and the resilient resource discovery and management scheme are experimentally demonstrated and theoretically analyzed. The results show that the proposed...
A testbed of OBS/GMPLS interworking network is established with the supporting of the BUPT-KDDI cooperation project. A dedicated GMPLS border controller with necessary GMPLS extensions and some OBS extensions are introduced in this network to achieve a dynamic, efficient and transparent inter-domain burst header packet (BHP) and data burst (DB) transmissions over the GMPLS-controlled optical circuit...
Various survivability schemes for the end-to-end transparent optical connectivity in OBS/GMPLS networks are experimentally demonstrated by using streaming media transmission. The results validate the applicability of such reliable connectivity to the high quality services.
Grid over OBS/GMPLS is successfully demonstrated and a self-organized resource discovery and management scheme is proposed for consumer Grid. High-speed TCPs for Grid are experimentally compared.
There are many factors which may effect network blocking probability in automatically switched optical network (ASON), such as call rate, average connection holding time, bandwidth etc. In this paper, the ASON network is simulated by Network Simulator 2 (NS2) and two uniform models which contain these factors are proposed to investigate ASON blocking probability. One model is focused on the call characteristic...
