Abstract:
A method for determining whether a packet stream which has been assigned a set of N assigned slot positions in a slot scheduling frame having FL slots, where FL&gE;N conforms to a predetermined conformance algorithm characterized by a peak packet emission interval and a packet delay variation time, said method comprising the steps of:(a) selecting a set of N ideal slot positions for said packet stream wherein said ideal slot positions are spaced apart from each other by a time substantially equal to said peak packet emission interval and wherein each assigned slot position of said set of N assigned slot positions ordinally corresponds to a respective ideal slot position of said set of N ideal slot positions; (b) determining a value ME, corresponding to a maximum amount by which each said assigned slot position is earlier than its said respective ideal slot position; (c) determining a value ML, corresponding to a maximum amount by which each said assigned slot position is later than its said respective ideal slot position; and (d) determining, based on a quantity ME+ML and said packet delay variation time, whether said packet stream conforms to said predetermined conformance algorithm.
