摘要： A method of managing transmission of a fragmented datagram in a network comprising end devices and intermediate routing or switching devices, wherein fragmentation of the datagram takes place at an upstream intermediate device, the method comprising:
- receiving and temporarily storing a first datagram fragment at a downstream intermediate device, the fragment including data allowing classification of the fragments of the datagram; and
- receiving and temporarily storing subsequent fragments of the same datagram at the downstream device until either:
i) all datagram fragments are received, at which time all fragments are classified and transmitted on based on the classification data of the first fragment; or
ii) a predetermined time period has elapsed and at least one fragment is missing, at which time an action other than transmission on to a subsequent device is initiated.
