摘要： The present invention provides a method building a handover system to improve the service quality in mobile networks. When a mobile node has received a plurality of care-of addresses, it will send a Prepare Multi-path (PM) message to a correspondent node. Once receiving the PM message, each router replaces the old input label in the PM message with a new input label, and then sends it to the next router. Each router adds a new item into the Split Path Table based on the received message. After sending the PM message, the mobile node sends a Request Multi-path (RM) message to a correspondent node. Each MPLS core router decides whether to stop the RM message or not when the RM message is received. If it is yes, the corresponding input label will be split and the generated data packet will be transmitted to two paths from this router. One is the path in the network where the mobile node has been located, another one is a new path in the visiting network.

摘要： A memory system for simultaneously extracting a desired block of data in response to an address specifying only the center bit of the block. The input address is modified through an arithmetic circuit wherein the address representing the center bit is added to and subtracted from to produce a plurality of addresses which are used to address a plurality of separate memory blocks. The outputs from the memory blocks are passed through a selection alignment matrix circuit which selects from the outputs of the memory blocks only those bits in the desired block of data and aligns those bits in a predetermined array. Bits other than those in the desired block of data are discarded.

摘要： In the bandwidth-allocating method of the present invention for PON (: Passive Optical Network), a bandwidth is allocated from an optical line terminal to each optical network unit. The optical line terminal stores a bandwidth contract table for indicating a correspondence relationship between communication flow IDs and service quality parameters, each communication flow ID identifying each communication flow between the optical line terminal and each optical network unit. The bandwidth-allocating method includes a step of transmitting a service-quality request message including the communication flow IDs and the service quality parameters from each optical network unit to the optical line terminal, and a step of the optical line terminal's updating the bandwidth contract table based on the service quality parameters, and performing the bandwidth allocation to a communication flow specified by the corresponding communication flow ID based on the bandwidth contract table.

摘要： There is a need to provide a multirate burst mode receiver for an OLT to be capable of receiving a high-speed burst signal without the need for a special capability of an ONU in a PON system including a mix of ONUs at different transmission bit rates. A multirate burst mode receiver according to the invention includes a signal input discrimination section and a bit rate discrimination section. The signal input discrimination section detects an average amplitude to discriminate signal input. The bit rate discrimination section detects an envelope curve for a high-frequency component to discriminate a signal bit rate. Based on a discrimination result from the signal input discrimination section and the bit rate discrimination section, the multirate burst mode receiver switches a setting for an optical signal reception section and a serial-parallel converter corresponding to the reception bit rate.

摘要： A passive optical network (PON) system includes at least one optical line terminal (OLT), a plurality of optical network units (ONUs) connected to each OLT, and an OLT management server used to manage the OLT. The OLT management server creates a VLAN access control table in response to a user's request to indicate a VID translation relation among different VLAN identifiers (VIDs) and sends a VID translation relation described in the VLAN access control table to the OLT, and the OLT creates a VLAN translation table indicating a correspondence relation between a source VID and a destination VID, which are waiting for translation, based on the received VID translation relation. If the OLT determines that a VID included in a received frame must be translated based on the VLAN translation table, the OLT references the VLAN translation table to translate the VID included in the received frame to a corresponding destination VID.
