Abstract: An event transport system using an RMT(Reliable Multicasts Transport) is provided to supply functions requested from a high-available system with only RTM by which multicast transport is enabled. An event transport management module(120) transports an event message transported from an application program through an RTM module(130). When transmission errors exceed the threshold value of the RMT module, the event transport management module transports a transport failure message to a mail box of a receiver. When an event transport system(100) restarts, the event transport management module requests the transport of an event list to the event transport system of the other nodes.

Abstract: A system for controlling resource management and call admission on an access network, and a method therefor are provided to determine the availability of resources and manage the resources in the whole section of the access network in a call admission control process for the IP communication service of a user through the resource management of the access network and the hierarchical resource management of the access path of the user, thereby improving service control and service quality in an end-to-end section. A system for controlling resource management and call admission on an access network comprises a resource information construction unit(131), a location information extraction unit(132), a connection unit(133), a resource availability determination unit(134), and a bandwidth allocation unit(135). The resource information construction unit collects the resource information of all equipment configuring the access network and constructs the resource information of the access network hierarchically. The location information extraction unit receives a connection request to the access network from a user and extracts the location information of the access network from the resource information of the access network hierarchically. The connection unit connects the extracted location information to the link information of the access network hierarchically constructed. The resource availability determination unit determines whether resources corresponding to the location information hierarchically constructed are available when a subscriber having access to the access network requests a call admission control request for an IP(Internet Protocol) communication service. The bandwidth allocating unit allocates bandwidth required to the IP communication service to a part of the link information and a residual bandwidth by service class to which the user belongs if the resources are available.

Abstract: An apparatus and a method for managing a forwarding information table according to the upgrading of software in a router system are provided to implement seamless packet forwarding, maintain QoS(Quality of Service), and improve system reliability by enabling necessary routing information for packet forwarding to be continuously maintained in a forwarding engine processor when the software of a routing processor is upgraded. An apparatus for managing a forwarding information table according to the upgrading of software in a router system comprises an upgrade management unit, a flag status change unit, a forwarding information table update unit, and a synchronization processing unit. The upgrade management unit, installed in a routing processor(101), requests a forwarding engine processor(102) to change the flag status of the forwarding information table when a routing protocol block(105) and a routing control block(104) stop. The flag status change unit, installed in the forwarding engine processor(102), changes the flag status of each entry of the forwarding information table according to the flag status change request from the upgrade management unit. The forwarding information table update unit, installed in the forwarding engine processor(102), receives a new forwarding information table from the routing control block(104) as the routing protocol block(105) and the routing control block(104) are rebooted, compares the entries of the new forwarding information table with the entries of the old forwarding information table, changes flag status for matched entries, and adds new entries to the old forwarding information table. The synchronization processing unit, installed in the forwarding engine processor(102), checks the flag status of each entry of the updated forwarding information table, and deletes an entry, of which the flag status is 'old', from the forwarding information table.

Abstract: PURPOSE: A method for selecting an RP(Rendezvous Point) in multicasting communication is provided to select an RP by using an existing routing protocol. CONSTITUTION: When an MR(Multicast Router) receives a routing protocol message(S301), it checks whether the message is valid(S302). If the message is valid, the MR checks whether a domain identifier and a group address are valid(S303,S304). If the domain identifier and the group address are valid, the MR compares an RP select priority value included in the received message and its own RP select priority value(S305). If the RP select priority value of the MR is higher than the RP select priority value included in the message, the MR discriminates whether transmission valid time has elapsed(S307). If the transmission valid time has not elapsed, the MR transmits a message that the MR is an RP of a corresponding multicast group to a different MR(S309) and is standby(S310).

Abstract translation: 目的：提供一种在组播通信中选择RP（Rendezvous Point）的方法，通过使用现有的路由协议来选择RP。 构成：当MR（多播路由器）接收路由协议消息时（S301），它检查消息是否有效（S302）。 如果该消息有效，则MR检查域标识符和组地址是否有效（S303，S304）。 如果域标识符和组地址有效，则MR将包括在接收到的消息中的RP选择优先级值与其自己的RP选择优先级值进行比较（S305）。 如果MR的RP选择优先级值高于消息中包括的RP选择优先级值，则MR鉴别传输有效时间是否已经过去（S307）。 如果传输有效时间还没有过去，则MR将MR是相应多播组的RP的消息发送到不同的MR（S309）并且处于待机状态（S310）。
