Abstract
A method is provided for controlling the misordering of packets in packet delivery in radio access networks (RANs) and other packet-switched networks. In one aspect, the method involves reading header information to determine the proper sequence of arriving packets, storing at least some packets that have arrived out of order, and forwarding the stored packets in a modified order that has no more than a specified degree of misordering.
Claims10
A method, comprising:
- receiving a plurality of lower-level packets having respective sequence numbers;
- reconstituting the lower-level packets as upper-level packets, wherein one or more lower-level packets are constituents of each said upper-level packet;
- and
- forwarding at least some of the upper-level packets for further processing, CHARACTERIZED BY:
- from some of the sequence numbers, determining that the constituents of at least one upper-level packet have arrived ahead of sequence by an amount DeltaSN corresponding to more than one sequential position;
- and
- delaying the forwarding of said at least one upper-level packet if DeltaSN exceeds a specified limit corresponding to more than one sequential position.
