PURPOSE: A node device for content streaming relay and a method thereof are provided to supply a content streaming service to a user terminal in a multicast or a unicast transmission mode according to a check result of content features and network states. CONSTITUTION: A server connection unit(100) selects a streaming server(12) by considering load distribution according to a streaming request signal of a user terminal(14). When content transmitted to the user terminal is overlapped, a content caching and unicast transmitting unit(120) transmits the overlapped content to the user terminal in a unicast mode. When the content is converted, a multicast converting unit(130) transmits the content to the user terminal in a multicast mode. [Reference numerals] (100) Server connection unit; (110) Address conversion and packet filtering unit; (12) Streaming server; (120) Content caching and unicast transmitting unit; (130) Multicast converting unit; (14) Terminal; (140) Control unit
