Asons: an automatically switched optical networks simulator
Computer Communications, 2005Automatically switched optical networks (ASONs) are emerging as a primary technology choice for telecom operators' and service providers' optical backbone networks. Although the ITU-T has published a recommendation for ASONs, intensive research work is still going on towards specifying the ASON protocols, as well as mechanisms that could be implemented

Research of the survival mechanisms in ASON
SPIE Proceedings, 2006This paper focuses on the survival mechanisms against single link failure for optical QoS services in ASON (Automatically Switched Optical Network). The new protection and restoration methods and optical QoS services enabled by ASON also bring new requirements.

Resource discovery in ASON/GMPLS Transport Networks
IEEE Communications Magazine, 2007Automatic resource discovery plays a significant role in next-generation optical networks, where nodes can maintain a large number of input/output ports (fibers, wavelengths, time slots, etc.). This automation avoids long and tedious manual node configurations and minimizes resource misconfiguration probability, which can result in high cost savings ...

Analysis of Switching Control Channels in Ason
2006 First International Conference on Communications and Networking in China, 2006The introduction of control plane in ASON enables optical network intellective for the first time. As the channel to transfer message in control plane, the reliability of control channel significantly influences the performance of network. In traditional mechanism, control node should report fault to manager when control channel is down. In this paper,

Design of a routing controller in ASON
SPIE Proceedings, 2004In this paper, according to the ITU-T recommendation G.8080, we present a novel architecture of RC based on the extended GMPLS, which consists of interface component, OSPF-TE component, route computation component and routing information database. The RC is emulated in the ASON simulation software developed by us, where the OSPF is extended as the ...

Research and simulation of ASON survivability testbed
SPIE Proceedings, 2007Automatically Switched Optical Network (ASON) is exciting technology in next generation optical network. And the reliable control plane plays a crucial role in creating high-level services in the transport network based on the Generalized Multi-Protocol Label Switching (GMPLS) or Automatically Switched Optical Network.

A novel dynamic p -cycle algorithm in ASON
SPIE Proceedings, 2006p-cycle provides a new protection scheme which provides fast protection switching time as that in ring networks and high resource efficiency as that in mesh networks. Extensive research has shown that the concept of p-cycle can also be applied to Automatically Switched Optical Network (ASON), which is the direction of the next generation optical ...

Multi-domain routing techniques in ASON networks
33rd European Conference and Exhibition on Optical Communication - ECOC 2007, 2007A pan-European ASON network has been simulated under dynamic traffic to compare the different multi-domain routing procedures allowed by the ASON Recommendations. Compared features are: network performance (blocking probability) and scalability (amount of required routing-information).

Achieving End-to-End Diversity over ASON Architecture
2006 Asia-Pacific Conference on Communications, 2006A novel mechanism has been proposed in this paper to set up diverse connections across ASON networks. The two connections sharing no common links or transport network elements enable complete end-to-end diversity over ASON architecture that including UNIs diversity, ENNIs diversity and diversity inside vendor's transport network. The proposed mechanism
