Abstract
Systems and methods are disclosed that allow for improved management and control of packet forwarding in network systems. Network devices and tool optimizers and a related systems and methods are disclosed for improved packet forwarding between input ports and output ports. The input ports and output ports are configured to be connected to source devices and destination devices, for example, network sources and destination tools in a network monitoring environment. The network devices and tool optimizers disclosed can use superset packet forwarding, such that ingress filter engines are configured with ingress filter rules so as to forward a superset of packets to output ports associated with overlapping filters. Egress filter engines are configured with egress filter rules to then determine which of the superset packets are actually sent out the output ports.
