An adaptive routing method and apparatus based on packet size are provided to set a route more properly and efficiently according to application or the packet size, thereby improving a transmission delay time or throughput to use a proper routing protocol according to the QOS(Quality Of Service) of each connection. A configuration of a node(200) having a routing protocol comprises a central processing unit(210), a routing processor(220), an application information extractor(230), a packet selection table(240), and a routing table(250). The central processing unit transmits received packets to the application information extractor if a routing request message is received. The application information extractor extracts application type information from a TCP/IP(Transmission Control Protocol/Internet Protocol) packet header, the received routing request message. The routing processor has the routing protocol, drivers the routing protocol to select a packet transmission route, searches the packet selection table to select packet size corresponding to received application information, and reflects the selected packet size to the routing protocol to set the packet transmission route. The routing table includes information about the packet transmission route.
