The advancement of communication technology and growth of internet traffic have continuously driven the fast evolution of networks. Compared to the traditional optoelectronic switch, all-optical switch provides high throughput, rich routing functionalities, and excellent flexibility for rapid signal exchange in fiber optical network. Among various all-optical switches, thermal actuated ring swi...

In this paper we investigate the performance of an Optical Code Division Multiplexing/Wavelength Division Multiplexing (WDM/OCDM) Optical Packet Switch when impairment due to both Multiple Access Interference and Beat noise are taken into account. Analytical models are introduced to dimension the switch resources, in particular the number of optical codes carried on each wavelength. The Packet ...

We discuss how all-optical signal processing might play a role in future all-optical packet switched networks. We introduce a concept of optical packet switches that employ entirely all-optical signal processing technology. The optical packet switch is made out of three functional blocks: the optical header processing block, the optical memory block and the wavelength conversion block. The oper...

For rapid service creation, software-defined network (SDN) controller is promising when establishing access networks on the all-photonics (APN). To our knowledge, no study has investigated fast restoration from SDN controllers with NETCONF/RESTCONF for high-reliability requirements. This paper proposes an automatic failure application a optical switch NETCONF/RESTCONF. It includes periodic devi...

This paper presents a new idea for the management of lambda-connections in optical networks. The idea consists of making multi-service optical switches responsible for automatically detecting IP flows at the packet-level, creating lambda-connections for them, and moving them to the optical-level. In addition to that, they are also in charge of tearing down the connections when no longer needed....
