    摘要： A packet communication apparatus includes a frame buffer of a linked list method and holds chain information and buffer size information, for structuring a linked list buffer for each user flow, in two areas consisting of an operation area and an update area. While usually in service, the buffer is structured by using the chain information in the operation area and the buffer size information in the same area such that the frame is read/written in the frame buffer. When the chain information in the update area and the buffer size information in the same area have been changed, a queue size is changed by reflecting the updated chain information and the updater buffer size information into the operation area, when both the read pointer and the write pointer respectively have gone around the buffer, or when there is no frame stored in the buffer.

    摘要： A packet communication system of this invention includes a user access device at a user point for providing a user with connectivity to a plurality of carriers, carrier communication networks linked to the user access device, and a carrier management network which controls and manages the user access device and communication devices. A communication device receives a control frame-inserting command from the carrier management network, and sends a control frame containing therein control frame transfer information that indicates which one of termination and send-back processing is performed at a destination device. In response to receipt of the control frame, a user access device that is the destination of this frame extracts therefrom the control frame transfer information. If this information indicates the termination then perform termination; if send-back, add thereto a header necessary for the send-back and then transfer it.

    摘要： Packet transfer device and method have both a processing procedure for uninterruptible-switching desiring packets and a processing procedure for low-delay desiring packets, and process each user packet according to a desired one of the processing procedures. The uninterruptible-switching desiring packets are set to be in phase by a delay unit and written into an uninterruptible-switching memory. The low-delay desiring packets are written into a low-delay memory without passing trough the delay unit, that is, without being delayed. A read-out controller reads out a packet from the uninterruptible-switching memory. When the read-out packet is an uninterruptible-switching desiring packet, the packet is directly output, and when the read-out packet is a low-delay desiring packet, the packet is discarded, and a low-delay desiring packet is read out from the low-delay memory and output.

    摘要： An identifier management apparatus capable of setting identifier conversion information of a new user without affecting identifier conversion processings of other users, and an identifier management method. The identifier management apparatus converts an identifier given to communication data. Its memory stores multiple hash functions, output values of the hash functions corresponding to the respective plurality of hash functions, multiple entry tables that manage the identifier conversion information indicating a correspondence between the input identifier being an input value of the hash function and an output identifier obtained by converting the input identifier, and a management table for managing a setting status of the identifier conversion information in each entry table. When registering the new identifier conversion information in any entry table, its processor selects an entry table that should register new identifier conversion information depending on setting statuses of the identifier conversion information in the entry tables.

    摘要： Provided is a network system including a start device and multiple end devices. A point-to-point (P-to-P) logical path is set to be used for unicast communication between the start device and each of the end devices. A first point-to-multipoint (P-to-M) logical path and a second P-to-M logical path are set to be used for multicast communication from the start device to the multiple end devices. The start device transmits data over the first P-to-M logical path. When one of the end devices detects a defect along the first P-to-M logical path, the end device that has detected the defect transmits a switch request over the P-to-P logical path set between this end device and the start device. The start device receives the switch request and transmits data over the second P-to-M logical path.
