Problems solved by technology

[0004] In the above-mentioned related technologies, the packet needs to pass through the switching network board to finally forward the packet to the service sub-card. The packet forwarding path is too long, which increases the probability of packet loss and error packet, and the forwarding efficiency is low.
Moreover, the bandwidth from the interface motherboard to the SFU will limit the number of packets that the distributed firewall device can process.

Embodiment Construction

[0067] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for thorough understanding of the application and to fully convey the scope of the application to those skilled in the art.

[0068] Such as figure 1 A structural diagram of a network device is shown. The network device includes an interface motherboard, at least one service sub-card, and at least one interface sub-card. Both the service sub-card and the interface sub-card are plugged into the interface motherboard. Wherein, the interface sub-card may be connected to the network, specifically, the interface sub-card may be connected to a CE (Customer Edge, user network e...

Abstract

The invention discloses a message forwarding method and device, the method is applied to network device, the device comprises an interface mother board, at least one service sub-card and at least oneinterface sub-card, and the service sub-card and the interface sub-card are inserted into the interface mother board; the interface sub-card receives the data message and transmits the data message tothe interface motherboard; and the interface motherboard matches the service identifier corresponding to the data message in a preset drainage rule, and forwards the data message to the service sub-card corresponding to the service identifier. According to the application, the message is sent to the service daughter card only through the interface mother board, and the message is forwarded without the switching network board, so that the forwarding path is shortened, the forwarding efficiency is improved, and the possibility of packet loss and packet error in the forwarding process is reduced. Even if packet loss and packet error occur, a problem port can be easily positioned and maintained. A switching network board is not required, the bandwidth from the interface motherboard to the switching network board is not occupied, and limitation of the bandwidth from the interface motherboard to the switching network board is avoided, so that the service flow which can be processed by the network equipment is larger.

Description

technical field [0001] The present application relates to network communication technology, in particular to a message forwarding method and device. Background technique [0002] Currently, the distributed firewall device usually adopts the mother-child card insertion method, that is, the switching network board is connected to the interface motherboard, and the service sub-card and the interface sub-card are plugged into the interface motherboard. Among them, the interface sub-card is used for receiving and sending the message, the switching fabric board is used for switching the message to other boards, and the service sub-card is used for processing the message. [0003] In the current related technology, after the interface sub-card receives the message, it sends the message to the switching network through the connection port between the interface sub-card and the interface motherboard, and the connection port between the interface motherboard and the switching network ...
