  • Publication number: 20230179509
    Abstract: In the flush of an FDB, as the number of user bases increases, more SWs are required to flush, and an influence on another user also increases due to flooding. The lapse of an aging time causes long-time communication interruption depending on network specifications and apparatus settings. In order to complete transmission of a user frame from the base after an accommodation change, it is necessary not only to do work of a communication carrier side but also to enter a user base. The present disclosure is a communication apparatus including a signal reception unit that receives a signal, a signal transmission unit that transmits a signal, and a frame generation unit that generates a control frame for updating a forwarding database (FDB) of a relay network on the basis of FDBs of apparatuses connected to the relay network. The signal transmission unit transmits the control frame generated by the frame generation unit to each of the apparatuses connected to the relay network.

  • Patent number: 11411859
    Abstract: A network device (PE), a network control method and program which can reduce a BUM traffic packet loss even when a time is taken for route recalculation according to a routing protocol due to a malfunction in a network infrastructure are provided. A network device according to the present invention requests each PE connected to the same ES as that of the network device to perform DF reelection on the basis of a redundant PE list from which the network device has been deleted when cease of a BGP session is detected. In addition, the PE requested to perform the DF reelection executes the DF reelection based on the redundant PE list from which the aforementioned PE has been deleted. In the present invention, BUM traffic can be immediately forwarded from a PE that has become a new DF even when a time is taken for route recalculation according to the routing protocol because another PE connected to the same ES is caused to serve as a DF when the BGP session is ceased.

  • Patent number: 11343181
    Abstract: An object of the present disclosure is to provide a provider network device, a network system, and a program that shorten a communication disconnection time during redundancy switching in a Single-Active redundant configuration. The provider network device according to the present disclosure notifies a CE that a VLAN, which has been communicating with traffic, is disabled due to setting of a block point or that new traffic communication is enabled due to releasing of the block point. This allows the CE to quickly delete a previously used transfer database and build up a new transfer database, and thus it is possible to shorten a communication disconnection time during redundancy switching.

  • Patent number: 11254049
    Abstract: A photocurable composition is supplied onto an auxiliary table provided to be capable of being adjacent to a fabrication table. One of the fabrication table and the auxiliary table is moved relative to the other one of the fabrication table and the auxiliary table in an up-and-down direction. The photocurable composition that has been supplied to the auxiliary table is drawn and spread by a recoater on a fabrication surface of the fabrication table or on a cured composition layer. The photocurable composition on the fabrication surface of the fabrication table is exposed by an exposure device, so that a cured composition layer is formed.
