Abstract
A novel apparatus and method of packet re-sequencing applicable to systems wherein packets are assigned sequence numbers and transmitted over multiple channels with the requirement they be re-ordered at the receiving side. The mechanism is particularly suitable for use in cable systems adapted to implement the DOCSIS 3.0 specification which permits the bonding of a plurality of downstream channels into a single virtual high data rate pipe. In operation, received packets are stored in a memory whereby a pointer to the memory storage location is written into a context table diagram in accordance with the sequence number extracted from the packet. Packets are released in sequence order regardless of the order in which they were received.
