Identification fragment handling

摘要

A device stores forwarding information associated with fragments of a first data unit, stores information common to the fragments of the first data unit, receives fragments of a second data unit, and forwards the fragments of the second data unit based on the forwarding information of the first data unit and the information common to the first data unit.

1. A method implemented by a device, the method comprising:
receiving, by the device, a fragment of a data unit; determining, by the device, whether the fragment of the data unit is a first fragment in a sequence of one or more fragments of the data unit; determining, by the device, forwarding information of the data unit when the fragment of the data unit is the first fragment; comparing, by the device, the forwarding information of the data unit to stored forwarding information,
the stored forwarding information being determined from another fragment of another data unit; and forwarding, by the device, the fragment of the data unit,
the fragment being forwarded based on the stored forwarding information when the forwarding information of the data unit matches the stored forwarding information, andthe fragment being forwarded based on updated forwarding information and updated fragment information when the forwarding information of the data unit does not match the stored forwarding information,
the updated forwarding information being stored and replacing the stored forwarding information, andthe updated fragment information being stored and replacing stored fragment information of the other data unit.
