The present invention relates to a method for establishing and releasing a connection in the Internet for minimizing the reliability of a resource reservation protocol and a load on a network in order to guarantee an Internet quality of service. A method for connecting and releasing a path using a resource reservation protocol (RSVP) in the Internet including a sending node, an intermediate node and a destination node, the sending node sending a route request message to the destination node through the intermediate node. Transmitting, by the intermediate node receiving the route request message, a response message; After the resource reservation is made, when the transmitting node transmits a resource reservation confirmation message to the destination node through the intermediate node, the intermediate node and the destination node receiving the resource reservation confirmation message respond with a response message. Two steps; A third step of receiving a connection status of the other party by periodically transmitting a connection status confirmation message between the nodes after the path is established; And a fourth step of the intermediate node and the destination node responding through a response message when the transmitting node transmits a resource release message to the destination node through the intermediate node. |
