Abstract

Computing a protocol complexity indicator (PCI) for a communication protocol of interest in a networked computer system that processes network traffic of multiple protocols. 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.

First claim

What is claimed is:

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;
creating a PCI mapping data set mapping the plurality of data communication protocols to their respectively corresponding PCI values;
receiving a predicted network traffic volume data set including information indicative of an expected total amount of network traffic and expected volume of network traffic under each protocol of the plurality of data communication protocols;
determining an amount of network bandwidth needed to handle the total amount of expected network traffic at a given speed based, at least in part, upon the expected network traffic under each protocol of the plurality of data communication protocols and the respectively corresponding PCI values of the PCI mapping table; and
determining an allocation of data communication network resources based, at least in part, upon the amount of network bandwidth needed to handle the total amount of expected network traffic at a given speed;
wherein the determination of allocation of data communication network resources includes computing a resource allocator value for each data communication protocol of the plurality of data communication protocols according to the following formula:

4. A computer program product (CPP) comprising:
a non-transitory data storage medium; and
computer code stored on the medium, with the computer code including machine readable data and instructions for causing a processor(s) set to perform at least the following operations:
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,

determining an amount of network bandwidth needed to handle the total amount of expected network traffic at a given speed based, at least in part, upon the expected network traffic under each protocol of the plurality of data communication protocols and the respectively corresponding PCI values of the PCI mapping table,
wherein the computer code further includes machine readable data and instructions for causing the processor(s) set to perform the following operation:
determining an allocation of data communication network resources based, at least in part, upon the amount of network bandwidth needed to handle the total amount of expected network traffic at a given speed,

wherein the determination of allocation of data communication network resources includes computing a resource allocator value for each data communication protocol of the plurality of data communication protocols according to the following formula:
