Abstract
In a packet switched network, a method and system order packets arriving out-of-sequence from a lower service. An ordering service temporarily buffers packets (101-115) while delayed packets arrive and forwards in-sequence packets to an upper service. Delay introduced by buffering does not accumulate as a propagation toleration timer (304) is activated for a predetermined time period (120) while awaiting the arrival of delayed packets or until the delayed packet arrives. Out-of-sequence packets are grouped between a lower-bound and an upper-bound of sequence identifiers to avoid accumulated delay due to repetitive lost packets.
