  • Patent number: 11025531
    Abstract: A hybrid access gateway receives packets that are sent by a network side device and are destined for a home gateway. When detecting that congestion occurs on a first transmission link and that no congestion occurs on a second transmission link, the hybrid access gateway obtains a first committed information rate (CIR) of the first transmission link and a second CIR of the second transmission link, classifies the packets into a first-type packet and a second-type packet, and transmits the first-type packet using the first transmission link and the second-type packet using the second transmission link. By properly allocating packets transmitted on the second transmission link, the hybrid access gateway can control one-way delays of the first transmission link and the second transmission link, thereby avoiding a packet loss caused by a sequencing buffer overflow.

  • Publication number: 20090161696
    Abstract: The disclosure discloses a method and system for complex flow classification of fragmented packets. The method includes determining whether a received fragment is an initial fragment, if the received fragment is an initial fragment, storing the initial fragment information and processing it, otherwise, looking for the matched initial fragment information, and performing the same action processing as the initial fragment. The application of the techniques provided in embodiments of the disclosure effectively solve the problem of complex flow classification of the fragmented packets based on the transport layer, thereby processing the initial fragment and its non-initial fragments with the same actions.
