Abstract:
통신방법및 장치가제공된다. 전송단말은하나이상의수신단말들에게패킷들을전송할수 있다. 수신단말은손실된패킷에대한추가적인요청을전송할지 여부를다른수신단말들의요청을감청한후 결정할수 있다. 전송단말은수신단말에대한추가적인요청에대해모두응답하지않고, 멀티캐스트를통해수신단말들에게전송된추가적인패킷들을고려하여응답여부를결정할수 있다.
Abstract:
인터레스트 패킷의 전송 시점을 결정하는 방법이 개시된다. 이전 인터레스트 패킷에 의해 마지막으로 요청된 컨텐츠 패킷이 컨텐츠 노드에 도착할 것으로 예측되는 예측 수신 시간을 산출하고, 산출된 예측 수신 시간에 기초하여 인터레스트 패킷의 전송 시점을 결정하는 인터레스트 패킷의 전송 시점을 결정하는 방법을 제공할 수 있다.
Abstract:
PURPOSE: A method for processing interest messages and data messages based on priorities in a content-centric network (CCN) is provided to offer different quality of service (QoS) based on type of contents by extracting a traffic type of each of the contents. CONSTITUTION: When priority queues (310) are located before a content store (330), a node included in a CCN extracts a traffic type of each of contents from each content name included in each of a plurality of interest messages. The node also determines priorities of the interest messages and processes the interest messages based on the determined priorities. The node determines whether each of the interest messages is a control message required to be processed in preference to a user message, based on the names of the interest messages. Additionally, the node extracts a traffic type to determine whether a corresponding interest message is a first control message, or a second control message. The node determines priorities of the interest messages based on the traffic type, and queues the interest messages in the priority queues based on the priorities. The interest messages queued in the priority queues are processed through the content store, a pending interest table (PIT) (350), and a forwarding information base (FIB) (370), based on the priorities of the interest messages. [Reference numerals] (310) Priority queues; (330) Content store; (350) Pending interest table (PIT); (370) Forwarding information base (FIB); (AA) Priority 1; (BB) Priority 2; (CC) Priority N; (DD,EE) Data message; (FF,GG) Interest message
Abstract:
PURPOSE: A control method of visiting a hub, home hub and mobile terminal in a virtual group for sharing content are provided to continuously share and transmit content while moving the content. CONSTITUTION: The request of the information about the network of a visitor virtual group which includes a visiting hum that manages a visiting virtual group from a terminal which moves to a visiting virtual group is received(210). Information about a network of a visiting virtual group to the terminal is transmitted by responding to the request(220). If the terminal is temporarily registered to the visiting virtual group by using the information about the network of the visiting virtual group, the information related to the visiting virtual group is received from the terminal(230). A hub list table is updated by using the information related to the visiting virtual group(240).
