摘要:
A proximity control method for transmitting a content and a network node using the proximity control method is provided. A proximity control method for transmitting a content performs a different proximity control mechanism depending on each of a single proximity control (SPC) domain, a mixed proximity control (MPC) domain, and a network-based service domain, and each of nodes performs the different proximity control mechanism based on a physical distance from a neighboring node, the nodes being comprised in the SPC domain, the MPC domain, and the network-based service domain.

An audio/vide bridging (AVB) system using an extended AVB reservation protocol, and a resource reservation method are provided where an AVB system using an extended AVB reservation protocol includes an egress device for transmitting a Generic Attribute Registration Protocol (GARP) or Multiple Registration Protocol (MRP) message comprising an AVB stream identifier or an application stream identifier to a relay device, the relay device for registering the AVB stream identifier or the application stream identifier according to the GARP/MRP message, and transmitting the GARP/MRP message comprising the application stream identifier, to an ingress device, and the ingress device for allocating the AVB stream identifier corresponding to the application stream identifier via the GARP/MRP message comprising the application stream identifier, and transmitting a reservation signal to the relay device.
摘要:
A system and method for determining a propagation delay between nodes in a packet network are provided. The system and method include sending a ping packet from a source node to a destination node, determining an intermediate node delay of the ping packet at an intermediate node and recording the intermediate node delay in the ping packet and determining the propagation delay at the destination node by using the intermediate node delay.
摘要:
A system and method of providing a quality of service (QoS) is provided. The method of providing the QoS in the link layer includes receiving, by a stream providing device, minimum and maximum resource requirement information of a stream receiving device; transmitting, by the stream providing device, a reservation message including the minimum and maximum resource requirement information; allocating a resource, by at least one bridge, based on the reservation message transmitted from the stream providing device; and receiving, by the stream receiving device, a stream transmitted from the stream providing device via the resource.
摘要:
A system and method for transmitting/receiving a call on a home network. When a request for call transmission/reception is made, a CP selects a target electronic device to/from which to transmit/receive a call from among at least one electronic device, establishes a connection for call transmission/reception between a terminal and the selected target electronic device, and controls the call transmission/reception between the terminal and the selected target electronic device.
摘要:
An instant service method and apparatus for deficit-round-robin (DRR) data packet scheduling are provided. The method includes servicing a current flow according to packet scheduling; activating a new flow according to an input of a new data packet; servicing the new flow immediately when the current flow service is completed; and servicing a next flow when the new flow service is completed. The apparatus includes a packet memory; a flow information storage; an active list processor; a main controller; and an output part.
摘要:
Provided are a guaranteed services method and apparatus in bridged LAN. streams are transmitted through bridges to a plurality of listener stations in a distributed network, and each bridge performs filtering, stream group registration and authentication for the streams. Accordingly, quality of service (QoS) in a distributed network can be improved. Furthermore, streams to the plurality of listener stations can be guaranteed.

A system and method for determining a propagation delay between nodes in a packet network are provided. The system and method include sending a ping packet from a source node to a destination node, determining an intermediate node delay of the ping packet at an intermediate node and recording the intermediate node delay in the ping packet and determining the propagation delay at the destination node by using the intermediate node delay.
摘要:
A method and system for measuring a distance between nodes in a packet network are provided. The system and method include measuring and storing a departure time of a ping packet sent from a source node to a destination node, sending a response packet with respect to the ping packet from the destination node to the source node, cutting through the ping packet or response packet to a successive node or the destination node without an intermediate node delay, computing a round-trip time by measuring an arrival time of the response packet at the source node and measuring the distance between the nodes, based on the round-trip time and speed of the ping packet.
