摘要： In an access network using optical switches, communications between an OLT and ONUs are established without a photoelectric conversion performed at an optical switching unit.The OLT controls the downlink optical switch SW(DOWN) to sequentially select each ONU in slots arranged in a discrete manner, and transmits a Discovery Gate message. Upon receipt of the Discovery Gate message, each ONU consecutively transmits Register Request messages. The uplink optical switch SW(UP) sequentially switch signals from ONU#1 through ONU#128 in the slots arranged in a discrete manner, and outputs the signals to the OLT, Some of the Register Requests transmitted from the respective ONUs pass through the SW(UP), and reach the OLT. Based on the received Register Requests, the OLT determines the timing of transmission for the ONUS, and notifies the ONUS of the timing of transmission through a Gate message.

摘要： An ATM switch includes a first stage, a second stage and a third stage each of which stages includes at least one basic switch, wherein the first stage, the second stage and the third stage are connected. The basic switch includes a part which refers to time information written in a header of an input cell and switches cells to an output port in an ascending order of the time information. In addition, the ATM switch includes a cell distribution part in the basic switch of the first stage. The cell distribution part determines a routes of a cell to be transferred such that loads of routes within the ATM switch are balanced. The ATM switch further includes an adding part which adds arriving time information to an arriving cell as the time information.

摘要： A network is realized having GMPLS and IP/MPLS mixed, in which an IP/MPLS node can be operated as is without replacing the IP/MPLS node with a node having a GMPLS function, even if the GMPLS and IP/MPLS are mixed.

摘要： A local switch serving a terminal constituting the destination of an IP packet is identified from the IP address of the packet, and time slot switching information is formed, this being information relating to a route through an STM network to this local switch. The packet can then be transferred through the STM network in accordance with this time slot switching information. As a result, a packet with an IP address can be transferred through an STM network.

摘要： A contention control circuit which temporarily stores cells arriving from a respective plurality of input lines to output cells to a single output line without collisions. The contention control circuit compares, at each input line in turn, the priority of the cell that has arrived from that input line, with the priority of the cell selected from among the cells that have arrived from preceding input lines as the cell having the highest priority, and again selects the cell with the higher priority.

摘要： An OVPN user register an L1 signal type information which is used in the user's device in an OVPN terminating device in advance together with an IP address and a VPNID which are allocated to the user's device. Registered contents are notified to other OVPN terminating devices which control the same VPNID as that of the user's device. Otherwise, when a calling connection request arrives from the user's device, the registered contents are notified other OVPN terminating devices which control the devices which receive the notification. By doing this, it is possible to handle a request by the user for changing the setting for the signal format which is employed in the user's device quickly. Also, it is possible to realize an OVPN which can perform a process for a calling connection request from the user efficiently and improve an operability for the user.
