Abstract
A system and method are provided for tracking connections in a network bundle including a plurality of network links. The method comprises: receiving packet fragments in a plurality of sampling rounds; for a current sampling round, recording which links have supplied a packet fragment; and, advancing a record of the received packet fragments in response a packet fragment on each link. Typically, the packet fragments are received with a corresponding first plurality of sequence numbers. Then, the lowest sequence number in the completed current sampling round is recorded. Some aspects of the method additionally comprise: for the current sampling round, establishing a flag register with a flag for each link; establishing a next lowest sequence number (Mn) register; and, establishing a current lowest sequence number (Mc) register. Then, a flag register flag is toggled in response to receiving a packet fragment on a corresponding link.
