The invention discloses a method for having a connection table in a chip support policy routing, which pertains to the filed of network safety and comprises the steps of the application of programmable gate array chips based on field and the connection with a CPU central processing unit. The method also comprises the steps that: the chip receives messages; resolution is carried out to obtain the 5-tuple content of input messages; the 5-tuple is taken out according to the resolution result and a connection table is searched for; if the target is hit, information is taken out and a forwarding outlet is recorded; if the target is not hit, the CPU is submitted; a safety strategy table is searched for, and a corresponding strategy routing table is applied according to a safety strategy rule, the forwarding outlet is determined and the connection information is written into the connection table in the chip and then to the forwarding outlet. The messages are sent out from the given forwarding outlet. The method redu
