The PCI provides an indication of predicted bandwidth usage by traffic of the protocol of interest. The PCI is used together with a throughput limit to establish a threshold amount for traffic of the protocol of interest. The PCI may then be used, for instance, to determine when to spawn a new instance of a network traffic-processing component for that protocol to maintain processing throughput at an acceptable level. ## Claims ### Claim 1 A method comprising: determining a plurality of Protocol Complexity Indicator (PCI) values respectively corresponding to a plurality of network data communication protocols, with each PCI value of the plurality of PCI values reflecting relative network usage bandwidth for a given amount of network traffic under the respectively corresponding data communication protocol;
