Abstract: An apparatus and a method for measuring the loss of frames in a multicast service environment are provided to measure the loss of frames accurately even without advance information about a change in a traffic route of the multicast service or a node from which traffic is outputted. An input frame-counting unit(200) counts data frames of a specific multicast service, which is included in a target net of which the loss of frames is to be measured. An output frame-counting unit(210) counts data frames of the specific multicast service, which is outputted from the target net. A loss-measuring unit(220) measures the frame loss by comparing the number of data frames counted by the input frame-counting unit with the number of data frames counted by the output frame-counting unit.

Abstract: A method and an apparatus for providing an Internet broadcasting service by using a fast buffering switch are provided to improve the delay of buffering generated as a video terminal stores initial streaming data in a buffer memory during a particular time when an Internet broadcast receiver switches a channel, thereby quickly switching the channel. An apparatus for providing an Internet broadcasting service by using a fast buffering switch comprises a channel message processing unit(324), a data storage unit(322), a broadcasting stream processing unit(321), and a broadcasting stream outputting unit(323). The channel message processing unit requests the transmission of streaming data for a broadcast channel through an access network(310) to which a user terminal requesting the reception of the broadcast channel is connected. A logical stream buffer is generated or deleted in the data storage unit. The broadcasting stream processing unit receives the streaming data for the requested broadcast channel from a broadcasting server(300), generates the stream buffer in the data storage unit, and stores the received streaming data. The broadcasting stream outputting unit copies the stored streaming data and transmits the stored streaming data to the user terminal in real time in order to perform multicast broadcasting.

Abstract: A flow terminating method using a change in packet length is provided to save network resources such as a communication channel and a buffer by predicting and determining an expected flow termination time according to a previously learned flow termination pattern in case a header field of the TCP(Transmission Control Protocol) or application, or a defined protocol signal cannot be used. A change in length of at least two packets that have been lately received among a packet flow is analyzed in a wired/wireless communication system that manages switching or a communication channel based on a packet flow. A flow termination time of the next packet is predicted and determined according to the analyzed change in the length of the at least two packets. The length information of the packets is classified based on the occurrence frequency of packets having the same size.

Abstract: A QoS providing method using an address system and an ARP(Address Resolution Protocol) are provided to simply reserve network resources required for QoS even without using a complicate protocol such as an RSVP(Resource ReserVation Protocol). When the current node receives a service request packet by using an address system and an ARP from a previous node, the current node checks QoS request information included in the request packet, and determines whether the requested QoS can be satisfied(S301,S303,S305). When the requested QoS cannot be satisfied, the current node includes the QoS request information in the service request packet and transmits it to the next node by using the address system and the ARP(S307). When a response packet with respect to the request packet is received from the next node, the current node determines whether the response packet satisfies the requested QoS(S309,S311). When the requested QoS is satisfied, the current node includes an address value of the current node satisfying the requested QoS in a response packet and transfers it to the previous node(S313).

Abstract: An apparatus and a method for controlling an input/output packet of a line card in a packet switching system are provided to prevent a waste of resources of a system due to traffic exceeding an output rate by supporting a rate limit function, and guarantee fair discard of the traffic exceeding the output rate. A packet classifying unit(110) classifies packets inputted according to a set input/output traffic limit rate. An ingress traffic limiting unit(120) controls an amount of input traffic of the classified packets, and when a packet having the same information is inputted according to information about traffic, exceeding an output bandwidth, which is provided from an output port of at least one line card within a packet switching system, the ingress traffic limiting unit(120) controls a processing amount of the corresponding packet. When a packet including identification information required for limiting an output rate is inputted from a line card of a destination, an egress traffic limiting unit(140) determines whether traffic of the inputted packet exceeds a pre-set bandwidth, and when the traffic exceeds the limited output bandwidth, the egress traffic limiting unit(140) provides the information on the traffic exceeding the output bandwidth to the ingress traffic limiting unit(120).
