it may detect packets which are intended to trigger changes in the table at 1010 as described above the host cpu may determine new table entries at 1060 or the discriminator may trigger changes in the decision table at 1070 without reference to the host cpu an example of a network management packet which might trigger a routing table change in local area network routing is a rip routing information protocol packet used for advertising routes if the discriminator detects packets which are intended to trigger reprogramming of the hardware as at 1015 this may cause the host cpu to download a new configuration to one or more of the fpgas at 1030 and 1040 alternatively the host cpu may change the fpga operation by changing an input or a register at 1050 0146 fig1 shows how a remote network manager may instruct a reconfiguration either by a table maintenance instruction 1020 or by a reprogramming instruction 1025 in either case the instruction may be sent by sending a packet across the network or conceivably by a distinct management communication path not shown as described above the packet can be passed to the host cpu which can thereby be instructed to download.
