TL;DR: The developed control system not only achieved autonomous distributed signaling and routing but also has a function that can adjust wavelength resources for optical packet and circuit switching autonomously in each link at each node.
Abstract: In this paper, we describe an autonomous distributed control system that we have been developing for an optical packet and circuit integrated network, and we experimentally evaluate its performance. Colored (i.e., multi-wavelength) optical packet-switched links transfer both control signals for circuit switching (e.g., signaling and routing) and best-effort packet data. We successfully transmitted high-definition uncompressed real-time video signals on two lightpaths established by our control system without degradation of video quality, simultaneously with other optical packet data transferred on the same optical fibers. Our developed control system not only achieved autonomous distributed signaling and routing but also has a function that can adjust wavelength resources for optical packet and circuit switching autonomously in each link at each node. Controllers achieved lightpath establishment within approximately 360 ms and dynamic resource adjustment within approximately 454 ms, in the best possible case in our experimental setup.

02 Mar 1976TL;DR: In this article, a character oriented transmission control procedure for communicating with its associated terminals is used in the packet switching network, where data terminals each having a single communication link connected with the packet switch network, whereby the data sending and receiving system is effectively effected and a flow control for the switching network can be achieved without using any special procedure in the control.
Abstract: A packet switching network in which the data transmitted from a data sending terminal is temporarily stored in a packet switching exchange connected to a data sender where the data is divided into a plurality of units each of which is called a packet and the data in turn is transferred with each packet unit to a packet switching exchange connected to a data receiver, through a number of transmit switching exchanges, and then those packets are reassembled into the original format of the data which finally is transmitted to a data receiving terminal, the above-mentioned packet switching network employing a data sending and receiving system in which a character oriented transmission control procedure for communicating with its associated terminals is used in the packet switching network, and the packet switching network involves data terminals each having a single communication link connected with the packet switching network, whereby the data sending and receiving system is effectively effected and a flow control for the switching network can be achieved without using any special procedure in the control.

TL;DR: An overview is given of a system designed to handle a heterogeneous and dynamically changing mix of applications that is based on fiber-optic transmission systems and high-performance packet switching and can handle applications ranging from low-speed data to voice to full-rate video.
Abstract: An overview is given of a system designed to handle a heterogeneous and dynamically changing mix of applications. It is based on fiber-optic transmission systems and high-performance packet switching and can handle applications ranging from low-speed data to voice to full-rate video. A novel feature is a flexible multipoint connection capability suitable for broadcast and conferencing applications. The architecture of a switching systems that can be used to support this network is described. >

TL;DR: Operation without packet alignment of an all-optical packet switch is proposed and predicted feasible through a detailed traffic analysis.
Abstract: Operation without packet alignment of an all-optical packet switch is proposed and predicted feasible through a detailed traffic analysis. Packet alignment units are eliminated resulting in a simple switch architecture while optimal traffic performance is maintained through the flexibility provided by WDM.

05 Jan 2005TL;DR: In this paper, a queue management method of an access network device includes receiving a packet, determining feasibility of a packet transmission within a delivery deadline allowed from a destination if the received packet is for real-time transmission, storing the packet in the transmission queue and transmitting the packet to the destination in sequential order of the storage when the packet transmission is feasible, and dropping the packet instead of storing the file in the queue when the file transmission is determined infeasible.
Abstract: A queue management method of an access network device includes receiving a packet, determining feasibility of a packet transmission within a delivery deadline allowed from a destination if the received packet is for real-time transmission, storing the packet in the transmission queue and transmitting the packet in sequential order of the storage when the packet transmission within the delivery deadline is feasible, and dropping the packet instead of storing the packet in the transmission queue when the packet transmission is determined infeasible. Accordingly, resources required for the packet transmission are saved.
