摘要： Provided is a passive optical network system for operating a mixture of PONs with differing transmission speeds and is capable of reducing power consumption on the basis of the amount of signals being transmitted. The master station of the passive optical network system, which determines the amount and timing of signals sent thereto by each of a plurality of slave stations on the basis of the requests of the plurality of slave stations and receives signals from the plurality of slave stations via an optical fiber network, is equipped with a control unit that determines in each set cycle the amount, transmission timing, and transmission speed of the signals that each slave station is permitted to transmit to said master station on the basis of the amount of signals that each of the plurality of slave stations has requested to transmit, and that notifies such to each slave station. Additionally, each of the plurality of slave stations is equipped with a control unit that transmits signals to the master station at a first transmission speed or a second transmission speed that is faster than the first transmission speed, and is configured to transmit signals with either the first transmission speed or the second transmission speed on the basis of notifications from the master station.

摘要： In a packet transmission router used in a VRRP (Virtual Router Redundancy Protocol) network having a VR (Virtual Router) function, when virtual routers VR are realized by the VRRP, the routing control information that each VR manages is prevented from being mixed with that of other VR. When an active packet transmission router transmits a VRRP packet to a standby packet transmission router, an identifier indicating which virtual router belongs to the VRRP packet is added to the VRRP packet before the transmission of the VRRP packet.

摘要： In a broadband access network, calls can be kept active even when a telephone network fails. A voice gateway function captures callee telephone number information sent from a caller subscriber telephone to the telephone network and, when the telephone network fails, keeps the call active by retaining the connection between the caller and the callee. Furthermore, when the telephone network fails, the operation mode of the voice gateway and all ONTs is switched from an H.248 gateway mode to an SIP softswitch mode, allowing the voice gateway function to relay communication packets between ONTs and new call connections to be made in the broadband access network.

摘要： A server having a function of authenticating a user, a function of confirming a connection state of the user by periodically transmitting a re-authentication request packet or a connection confirmation packet to the user and receiving a response, and a function of setting policy routing of an access server is used. A terminal communicates with the server instead of a Web browser to perform authentication at the initial start-up stage, and activates a client for responding to the re-authentication request packet or connection confirmation packet to thereby retain the connection state. Alternatively, a server having a function of authenticating a user is installed at the position of the authentication Web server. The terminal communicates with the server instead of the Web browser to perform authentication at the initial start-up stage, and a client for periodically performing authentication is activated thereafter to thereby retain the connection state.

摘要： A user terminal sends a resource reservation request message in which time information indicative of time to perform a communication is designated to a switching node to which the self user terminal is linked. The switching node manages a reservation state of each of resources which can be used by the self switching node among resources of a network together with time information indicative of time when a communication using the resource is performed. When the resource reservation request message is received, an unreserved resource is obtained at a time indicated by the time information designated in the resource reservation request message, the obtained resource is reserved, and a resource reservation result notice message indicative of the reservation result is returned to the user terminal. A resource management server is also provided so as to reserve a network resource with a simple operation. The reservation can be performed in consideration of priority and cost of a communication. Reservation information can be always recognized by a client. When resource reservation is failed, an alternative plan is automatically calculated and presented.
