In an example, a method for packet classification may include cyclically splitting an initial rule set to generate multiple rule subsets, performing tree building for each rule subset to obtain multiple decision trees. The cyclic splitting may select a target rule set having a highest global average overlap rate, from a rule set group which includes the initial rule set before the cyclic splitting and will include the multiple rule subsets after the cyclic splitting; split the target rule set according to a split point to obtain two rule sets; add the two rule sets into the rule set group to replace the target rule set; and continue to select a new target rule set from the rule set group, until the number of rule sets in the rule set group reaches a preset number.

A data forwarding device includes server interfaces virtual network cards, a fusion switch and a network interface. A server interface obtains a data frame sent by a virtual network card driver running on a server corresponding to the server interface and obtains a first fusion descriptor, and sends the first fusion descriptor and the data frame to a virtual network card unit that corresponds to the virtual network card driver. The first fusion descriptor includes a type of the descriptor and a length of the data frame. The virtual network card processes the data frame according to the first fusion descriptor, and sends the data frame to the fusion switch. The fusion switch sends the data frame to a corresponding server via a virtual network card, or sends the data frame to an external network via a network interface.

Data forwarding to server via virtual network card or to external network via network interface, based on fusion descriptor

The present invention discloses a long-reach Ethernet system. The system includes a first Ethernet device and a second Ethernet device which communicate with each other, and a relay; wherein one of the first Ethernet device and the second Ethernet device is a conventional Ethernet device, and the other one of the first Ethernet device and the second Ethernet device is a conventional Ethernet device or a long-reach Ethernet device; the first Ethernet device and the second Ethernet device communicate with each other via the relay; and the relay is adapted to transform conventional Ethernet data into long-reach Ethernet data and transform long-reach Ethernet data into Ethernet data. The present invention can realize the communication of two Ethernet devices when at least one of the two Ethernet devices is a conventional Ethernet device and a working distance between them is longer than 100 meters.
