Abstract: An apparatus for providing quality of service (QoS) of voice over IP (VoIP) traffic on IP routers and a forwarding method therefor are provided. The VoIP quality of QoS providing apparatus in an Internet protocol (IP) network containing data traffic and providing VoIP service includes: a softswitch which performs a VoIP call coordination function in the IP network and transmits VoIP call connection information in a multicast transmission method; and a router which provides QoS in forwarding a VoIP packet, by using the information received from the softswitch. With the VoIP QoS service providing apparatus, reliable multicast transmission method is enabled in providing VoIP connection information to each router, and when a softswitch additionally processes related functions, the load to the system is reduced.

Abstract: PURPOSE: A method for processing a call request with bifurcation by using an SIP(Session Initiation Protocol) and a call processor thereof are provided to reliably manage a call state and quickly respond to a call request by performing a forking operation once an OK response message is received from one bifurcated call without waiting for a message from the other bifurcated call. CONSTITUTION: A forking proxy core engine(111) manages call state as well as transaction state and especially manages call state information on forking. When an event is received and if it is a non-stored request message, the forking proxy core engine(111) creates a user agent server(113) and determines whether the message is to be forked. If the event is a previously stored request message, the forking proxy core engine(111) processes the message according to a state of the user agent server(113) or a user agent client. If the event is a response message to a call request, the forking proxy core engine(111) stores it in a forking storage unit(112) or processes it without storing it according to a state code of the response message to a bifurcated message. A session managing module(110) searches the forking storage forking storage unit(112) and reads information on whether to operate a user agent client to the end.

Abstract: PURPOSE: A network management method using availability is provided to compare an availability prediction value calculated through a reliability analysis before operating a network management system with an availability measurement value calculated during network operation and set a suitable maintenance time again. CONSTITUTION: A network manager calculates an MTBF(Mean Time Between Failures) according to each network management agent, and calculates a prediction availability value using the MTBF(S301). If fault is generated in a specific network management agent before a maintenance time set by the prediction availability value elapses(S303,S304), the network manager receives the notification of the fault generation and calculates an MTBF measurement value of the specific network management agent(S305). The network manager recovers the fault of the specific network management agent(S306). The network manager calculates an MTTR(Mean Time To Repair) measurement value until the recovery of the fault is completed(S307), and calculates a measurement availability value of the specific network management agent(S308). The network manager compares the prediction availability value with the measurement availability value, and sets a less value as a maintenance time again(S309,S310,S314).

Abstract: PURPOSE: A packet transfer method for duplexing protocols of a network layer and a transmission layer is provided to enable protocols to perform the same process simultaneously in an active board and a standby board. CONSTITUTION: Virtual interfaces(103,113) handle a task related to a path of packets. A packet having layer header information(201-203) comes into an active main processor board(101). When the packet passes a virtual interface layer(L2), its L2 layer header(MAC header(201)) is removed and thus the packet is changed to a packet(205) having only an L3 header. The packet(205) is copied so that the original one(205) is transferred to an upper protocol stack(102) and the copied packet(207) is transferred to a processor board(116) in a standby state through a duplex ether path(104). When the copied packet(207) is transferred, the L2 layer header(MAC header(201)) is attached to the copied packet(207). Accordingly, Ethernet physical device(105) of the active processor board(101) and the Ethernet physical device(112) of the standby processor board(116) have the same MAC address and IP address.
