Description

technical field

[0001] The invention relates to a network route control method and a network relay device. Specifically, the present invention relates to routing of data information packets using application layer data identification information contained in the data information packets in order to efficiently transmit multimedia data such as images and sounds and large-capacity data such as enterprise internal technical data. The data transmission method and its relay device, especially relate to the data transmission method using the address of the storage part in the network with the storage device as the constituent element, the data storage type transmission method and its relay device. Background technique

[0002] In the conventional network system, the routing technology of the network layer protocol based on the ISO reference model is used. The main protocols include: Routing Information Protocol (RIP) that determines the optimal route based on the number of router...
