Rapid channel failure detection and recovery in wireless communication networks is needed in order to meet, among other things, carrier class Ethernet channel standards. Thus, resilient wireless packet communications is provided using a physical layer link aggregation protocol with a hardware-assisted rapid channel failure detection algorithm and load balancing, preferably in combination. This functionality may be implemented in a Gigabit Ethernet data access card with an engine configured accordingly. In networks with various topologies, these features may be provided in combination with their existing protocols.

A system and method for distributing packets in a network arc disclosed. The method comprises a step of receiving at least one data packet at a first node front a second node. The method also comprises a step of determining a current set of weights which are applied by the second node to distribute data packets across the first plurality of links. The received data packets are analysed to determine if the current set of weights are to be adjusted (step S102). When it is determined that the current set of weights is to be adjusted, an adjusted set of weights is generated by determining an adjustment factor (step S104). The adjustment factor is applied to the current weight for the selected link and at least one other current w eight in the current set of w eights.

Embodiments of the present invention provide a traffic flow splitting method and apparatus. In a process of accessing a 3GPP network by UE, an eNB in the 3GPP network sends a first multiflow aggregation instruction to the UE, to instruct the UE to establish a first multiflow aggregation channel between the UE and the eNB via a non-3GPP network. The UE establishes the first multiflow aggregation channel. The first multiflow aggregation channel is used for transmitting a part of data in a downlink traffic flow for the UE, where the part of data is offloaded to the non-3GPP network for transmission, and other data in the downlink traffic flow is offloaded to a 3GPP channel for transmission. In the method, different data packets in a same traffic flow can be simultaneously transmitted in the 3GPP network and the non-3GPP network.

Embodiments of the present invention provide an access network system, and a data packet processing method and apparatus. The system includes: a controller, configured to perform configuration a flow table for a switching module and a protocol function for at least one functional module; the switching module, configured to send a first data packet to a first functional module of the at least one functional module according to the flow table configured by the controller, where the first functional module is a functional module first indicated in the flow table to process the first data packet; and the at least one functional module, configured to process the first data packet according to the protocol function configured by the controller.

A packet processing method and a network device in a hybrid access network. The method comprises sending, by a first network device, a first data packet in a first sending window to a second network device by using a first tunnel. In response to receiving a first acknowledgement response sent by the second network device, increasing, by the first network device, a size of the first sending window based on a first proportion. In response to not receiving, within a first predetermined time, the first acknowledgement response, decreasing the size of the first sending window based on a second proportion; and in response to determining that the size of the first sending window is greater than or equal to a first threshold, sending a second data packet to a second receiving window of the second network device by using a second sending window.
