Problems solved by technology

However, when the interface board receives the message sent by the source device to the destination device, it will send the message to a service board for processing, and when the interface board receives the message returned by the destination device to the source device, it will send the message to the source device. The message is sent to another service board for processing, that is, there is no guarantee that the message will be assigned to the same service board for processing

Embodiment 1

[0039] Aiming at the problems existing in the prior art, an embodiment of the present invention provides a message transmission method, which is applied to a network device including multiple service boards, such as a distributed firewall including multiple service boards. Such as figure 1 As shown, it is a schematic diagram of a network of a distributed firewall. The distributed firewall is composed of a switching network, a main control board, an interface board (one or more) and multiple service boards. Among them, the main control board is used for processing configuration and routing, etc., and does not participate in forwarding processing. The interface board is used to receive the message, and send the message to each service board in a balanced manner based on the HASH (hash) algorithm. The service board is used to independently process services such as session establishment, packet forwarding, L2TP, and QoS (quality of service). Since there are multiple service boar...

Embodiment 3

[0084] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a service board as the first service board, such as Image 6 As shown, the first service board includes:

[0085] The receiving module 11 is configured to receive the first data message sent by the source device to the destination device;

[0086] The processing module 12 is configured to: if the first data packet carries a tunnel encapsulation header, there is no correspondence between the first address information and the identity of the first service board in the first service board, and there is no correspondence between the second address information and the first service board identifier. According to the corresponding relationship between the identifiers of other service boards, perform service processing on the first data packet;

[0087] A generating module 13, configured to generate and record the correspondence between the first address information a...

Abstract

The invention discloses a message transmission method and a service board. The method comprises: receiving a first data message by using a first service board; if the first data message carries a tunnel packaging head and the first service board is not provided with a corresponding relation between first address information and the identifier of the first service board and a corresponding relation between second address information and the identifiers of other service boards, performing service processing on the first data message, determining a second service board receiving second data message by using the first address information, and sending the corresponding relation between first address information and the identifier of the first service board to the second service board; sending the second data message to the first service board when the second service board receives the second data message; and receiving the second data message and performing service processing on the second data message by using the first service board. The method guarantees a fact that a message transmitted from a source device to a target device and a message returned from the target device to the source device are processed by the same service board of a distributed firewall.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a message transmission method and a service board. Background technique [0002] The distributed firewall processes services in parallel through multiple service boards, so as to improve the processing performance of the distributed firewall and meet the user's requirements for high concurrency, high construction, and high throughput. In order to give full play to the performance of a distributed firewall, a distributed firewall usually consists of a main control board, an interface board, and multiple service boards. Based on this, after receiving the message, the interface board will send the message to each service board in a balanced manner based on the HASH (hash) algorithm. After receiving the message, each service board will independently process services such as session establishment, message forwarding, and L2TP (Layer 2 Tunnel Protocol, Layer 2 Tunnel Protocol). ...
