Abstract: A link state update system and a control method thereof which efficiently calculates QoS guaranteed route are provided to sense a varied link state and update the link state update. A router unit(300) calculates a QoS guaranteed route satisfying the bandwidth according to a guarantee path setup request. The router sets up the QoS guaranteed route according to whether the route of being calculated exists in the database. A link management unit(500) changes the link status information of the QoS guaranteed route. The link manage changes link according to the QoS guaranteed route of being set up by using the changed link status information. In case the predetermined link information update threshold value is actually greater than one among the available bandwidth of the QoS guaranteed route and the available bandwidth, a database management system(700) renews database by using the changed link status information.

Abstract: A wireless mesh network structure and a method for transmitting data on a wireless mesh network are provided to improve the collision of data frame, the decrease of network throughput due to unnecessary back off, and the increase of delay by using PCF instead of using DCF. A wireless mesh network structure is comprised of MP(15), MAP(20), and MPP(10). PCF which is the contention-free channel access method is used as the multi-hop data method of delivery performed in the mesh bag bone from MPP to MAP. PCF(Point Coordination Function), a contention free channel access method, is used as a mesh network wireless backbone providing wireless communication service to a plurality of user terminals through wireless hop communication between MP(Mesh Point) and a multi hop data delivery method which is performed in a mesh backbone from MPP(Mesh Portal) to MPA(Mesh Access Point). DCF(Distributed Coordination Function), a competitive channel access method, is used for a data transmission between MAP as described above and a user terminal.

Abstract: A method for operating a sleep mode for efficient energy management of a mobile terminal is provided to reduce repetition of a sleep interval and a listening interval from a time after the mobile terminal is converted into a sleep mode in a sleep mode algorithm of IEEE 802.16e to a time when data to be received is generated. A method for operating a sleep mode for efficient energy management of a mobile terminal comprises the following steps. A sleep interval value is checked when terminating a sleep mode of the mobile terminal. The amount of data packet stored in a buffer of a base station is checked. The base station sets the minimum sleep interval to be used in the next sleep mode of the mobile terminal based on sleep interval information when a previous sleep mode is terminated.

Abstract: An upstream transmission band allocation method in a WDM(Wavelength Division Multiplexing)-based EPON(Ethernet Passive Optical Network) is provided to enable efficient band allocation by managing ONUs(Optical Network Units) by group, and to prevent unused channel sections from being generated. ONUs to be allocated to each of m wavelength channels are grouped(S1). So that the grouped ONUs use efficiently allocated wavelengths and time slots, dynamic band allocation algorithm is carried out to allocate each channel. The m wavelength channels are synchronized with one period. The one period is set based on a maximum permissible period. The m wavelength channels are synchronized with sub periods created by dividing the one period into m periods. The overall ONUs are grouped into m+1. The grouped ONUs start to transmit upstream frames at starting time of the synchronized period and sub periods.

Abstract: PURPOSE: An ER-LSP(Explicit Routed-Label Switched Path) management method for admitting the fault of an MPLS(Multi Protocol Label Switching) system and an apparatus therefor are provided to prevent that unnecessary control messages are generated by the resetting of all ER-LSPs by managing LDP(Label Distribution Protocol) session information and state information according to the ER-LSPs and resetting only a corresponding ER-LSP by stored information when an LDP session is connected after a system and link fault is removed. CONSTITUTION: An ER-LSP database(40) stores an ER-LSP ID, an ER-LSP state, link information, and a link state with respect to each ER-LSP. An ER-LSP setup/release management unit(20) manages the setup and release of the ER-LSP. A state informing block performs a line recovery and LDP session setup informing function and a link fault and LDP session release informing function. If the fault of the LDP session and link is sensed by the state informing block, an ER-LSP fault management unit(60) performs the fault management function of the ER-LSP, releases assigned resources, and releases internal switch connection setup. If the state of the ER-LSP is changed by the ER-LSP setup/release management unit(20) and the ER-LSP fault management unit(60), an ER-LSP state management unit(30) changes ER-LSP state information and LDP session information of the ER-LSP database(40). When the LDP session setup is sensed by the state informing block, an ER-LSP resetting task block(90) requests resetting with respect to the ER-LSP of the setup state and the ER-LSP of a down-state.

Abstract: PURPOSE: A method for providing extranet VPN(Virtual Private Network) service in an MPLS(Multi Protocol Label Switching) network is provided to offer intranet VPN service and extranet VPN service at the same time, without having an effect on an old service providing mechanism, by utilizing a route target and a VPN label variable used in existing MPLS VPN intranet service. CONSTITUTION: A VPN packet processing procedure at an MPLS terminal side is divided into egress forwarding, extra-gate forwarding, and relay forwarding. In order to effectively classify it, a VPN label is composed of a 2-bit label type classifier(401) and 18-bit label index information(402). The 2-bit label type classifier(401) indicates a forwarding method, and the 18-bit label index information(402) indicates an output IF or an index for a table for access filtering. If a VPN packet is received, an extranet gateway and egress LER checks the VPN label value carried with the received packet and recognizes which procedure to be executed.
