Abstract: A network routing system and a network packet routing method thereof are provided. The network routing system includes a control server and a network switch. The control server creates a first routing configuration based on topology of the network routing system. The first routing configuration includes a first routing information match field and a first routing setup field. The control server transmits the first routing configuration to the network switch. The network switch receives a first network packet from a first network node, and determines that a piece of first routing information of the first network packet matches the first routing information match field. The network switch creates a second routing configuration according to the first routing setup field. The second routing configuration includes a second routing information match field and a second routing setup field.

Abstract: A packet transmission system is provided that includes packet switching modules each having a memory unit to store packet flow tables and a control module coupled to the packet switching modules. The control module includes a memory to store computer executable commands and a processor. The process executes the commands to perform the operations outlined below. A flow entry corresponding to a target packet switching module is generated. A residual memory amount of the memory unit of the target packet switching module is determined to be lower than a threshold value. A redirection packet switching module is selected from the other packet switching modules. A redirection flow entry is added to the packet flow tables in the target packet switching module and a processing flow entry is added to the packet flow tables in the redirection packet switching module according to the flow entry.
