A routing processing system in a packet transmission is capable of
restricting a delay in a routing process based on particular applications
being utilized. The packet transmission routing processing system performs
a routing process for an input packet and includes parsing and timer
processing for identifying an application corresponding to an intended
transmission of an input packet and monitoring a timer value provided for
the application. Routing and transferring processes determine a
transmission destination port on the basis of a destination address stored
in a routing table, and dispose of the packet or transfer packet to a
preliminary determined route depending on the identified application when
routing process exceeds the timer
