Patent ID: 8417826

Claim:
A method of data traffic control in a communication network, the method comprising: comparing a measured processor occupancy (PO) level of a network processing unit to a target PO level; and based on the comparison, controlling via at least one controlling operation at least one data traffic load source associated with the processing unit until the measured PO level falls to a level at or below a designated PO level, wherein: the at least one data traffic load source is a source of extant or potential data traffic through the processing unit or a network control factor relating thereto; at least one further load source is associated with the processing unit, each load source having a respective quality of service (QOS) level; the controlling operation is able to give different treatments to data flows having different QOS levels; the controlling operation is performed so as to reduce, by means other than dropping of calls, a selected processor load due to at least one admitted packet flow; and the selected processor load is selected based on its QOS level.
