Optical circuit-switched networking has been proposed but it is reconfigurable in milliseconds. Although switches operating on nanosecond timescales have been demonstrated, centrally scheduling such switching architectures is considered to be of high complexity, incurring significant delay penalties on the total switching latency. In this paper we present a high-speed control plane design based on a central switch ...

The use of a processor for switch control gives greater flexibility, allows the implementation of sophisticated diagnostics, and, with high-speed interswitch signaling, reduces overall call set-up times. The proposed network is hybrid in that it can operate in a conventional circuit switched mode, or operate in a "packet" switched mode. ...

Abstract Because new microcellular systems have high‐speed transmission, they are expected to provide the infrastructure for voice and data communication. To implement packet radio communication on such systems, packet channel sharing protocol for DCA systems (PCSD) scheme is proposed for sharing dynamically assigned TDMA channels with circuit‐switched calls. In this protocol, packet channels are temporally established only when packets are generated. This is done by transmitting downlink signals, consecutively, ...

An architecture of an all-optical multistage interconnection network is proposed. The network supports a circuit-switching model of communication and can provide parallel optical paths among input and output ports. It uses an address-based routing algorithm for path setup which, due to its decentralized nature, makes this network suitable for designing high-speed switching systems. These switches are commonly used in telephony and multiprocessor systems. The proposed architecture uses bistable optical ...
