摘要： Provided are a large-scale cluster monitoring system and a method for automatically building/restoring the same, which can automatically build a large-scale monitoring system and can automatically build a monitoring environment when a failure occurs in nodes. The large-scale cluster monitoring system includes a CM server, a BD server, GM nodes, NA nodes, and a DB agent. The CM server manages nodes in a large-scale cluster system. The DB server stores monitoring information that is state information of nodes in groups. The GM nodes respectively collect the monitoring information that is the state information of the nodes in the corresponding groups to store the collected monitoring information in the DB server. The NA nodes access the CM server to obtain GM node information and respectively collect the state information of the nodes in the corresponding groups to transfer the collected state information to the corresponding GM nodes. The DB agent monitors the monitoring information of the nodes in the groups, which is stored in the DB server, to detect a possible node failure.

摘要： Provided is an availability prediction method for a high availability. The method includes calculating a basic survival probability that the other node survives until a failure on one node of two nodes constituting a cluster is fixed, and determining an optimal number of nodes meeting a preset reference availability probability by calculating an availability probability for a predetermined range of the number of nodes on the basis of the basic survival probability. The method determines the number of nodes in the high availability cluster so as to match a reference availability probability, and is able to accomplish an optimal configuration of a cluster by calculating the availability probabilities for combinations between active node and passive nodes and between head nodes and switches.

摘要： A method and apparatus for providing a peer-to-peer (P2P) based streaming service are provided. The method provides a streaming service in a peer-to-peer (P2P) network comprising a plurality of peers. That is, a receiving peer requests a plurality of transmitting peers having contents for a streaming service among peers in the P2P network to transmit the contents. Then, the receiving peer receives identical portions of the same content from the plurality of transmitting peers at the same time. After receiving, the receiving peer provides a streaming service for the received content from a first transmitting peer among the plurality of transmitting peers to a user.
