摘要： A network connection device allowing high-speed data conversion to ensure sufficiently high throughput is disclosed. The network connection device includes a plurality of conversion processors and a layer-4 switch. The layer-4 switch forwards an incoming IP packet to a selected one of the plurality of conversion processors depending on a result of analyzing the IP packet at layer 4. Therefore, the processing of data packet and the processing of control packet can be performed in parallel by the plurality of conversion processors, resulting in high-speed packet transfer.

摘要： A network switch includes a buffer to store network packets and packet descriptors (PDs) used to link the packets into queues for output ports. The buffer and PDs are shared among the multiple traffic pools. The switch receives a multicast packet for queues in a given pool. The switch determines if there is unused buffer space available for packets in the given pool based on a pool dynamic threshold, if there is unused buffer space available for packets in each queue based on a queue dynamic threshold for the queue, if there are unused PDs available to the given pool based on a pool dynamic threshold for PDs, and if there are unused PDs available for each queue based on a queue dynamic threshold for PDs for the queue. The network switch admits the packet only into the queues for which all of the determining operations pass.

摘要： A multimedia streaming service system is provided that includes a VOD server to sequentially transmit a header (moov) and media data (mdat) of MP4 contents in a TCP packet and a client to transmit a streaming service request signal in HTTP to the VOD server. The client may accumulate the media data (mdat) received from the VOD server in a decoder buffer for a predetermined time, and reproduce the data on a real time basis. A guaranteed rate of QoS may be enhanced as compared to an RTP/UDP-based streaming method. A service delay time may be reduced as compared with a TCP-based downloading method, thereby implementing contents on a real time basis.
