IP 망에서의 액티브 노드 발견 및 액티브 패킷의 신뢰성 전송 기법

Abstract

All active nodes which have no physically direct connection with each other in IP network must be able to compose and manage network topology informations. Besides one active program can be performed by the active nodes when every active packet for this program is transmitted without any loss of packets. Also the active packets should be transmitted effectively to minimize the transmission delay and securely from threatens. In this thesis, the discovery scheme of active nodes is adapted for active nodes in IP networks to compose and manage the topology information. The scheme for the efficient, reliable and secure transmission of active packets is also proposed. The sequence number is assigned to every active packet. If a receiver detects the loss of active packet checking the sequence number, the receiver requests the retransmission of the lost packet to the previous active node. After receiving an active packet and adapting security and reliability schemes, intermediate active nodes not only copy and send the packet instantly but also apply some security mechanisms to it. And the active packet transmission engine is proposed to provide these transmission schemes. The simulation of the adapted active node discovery scheme and the proposed active packet transmission engine is performed. The simulation results show that the adapted active node discovery scheme is efficient and the proposed active engine has the low latency and the high performance.
